<title>Ischemic Postconditioning Protects Neuronal Death Caused by Cerebral Ischemia and Reperfusion via Attenuating Protein Aggregation</title> 
<description><![CDATA[ <p><b>Objective:</b> To investigate the effect of ischemic postconditioning on protein aggregation caused by transient ischemia and reperfusion and to clarify its underlying mechanism.</p><p><b>Methods:</b> Two-vessel-occluded transient global ischemia rat model was used. The rats in ischemic postconditioning group were subjected to three cycles of 30-s/30-s reperfusion/clamping after 15min of ischemia. Neuronal death in the CA1 region was observed by hematoxylin-eosin staining, and number of live neurons was assessed by cell counting under a light microscope. Succinyl-LLVY-AMC was used as substrate to assay proteasome activity in vitro. Protein carbonyl content was spectrophotometrically measured to analyze protein oxidization. Immunochemistry and laser scanning confocal microscopy were used to observe the distribution of ubiquitin in the CA1 neurons. Western blotting was used to analyze the quantitative alterations of protein aggregates, proteasome, hsp70 and hsp40 in cellular fractions under different ischemic conditions.</p><p><b>Results:</b> Histological examination showed that the percentage of live neurons in the CA1 region was elevated from 5.21%&#177;1.21% to 55.32%&#177;5.34% after administration of ischemic postconditioning (<i>P</i>=0.0087). Western blotting analysis showed that the protein aggregates in the ischemia group was 32.12&#177;4.87, 41.86&#177;4.71 and 34.51&#177;5.18 times higher than that in the sham group at reperfusion 12h, 24h and 48h, respectively. However, protein aggregates were alleviated significantly by ischemic postconditioning to 2.84&#177;0.97, 13.72&#177;2.13 and 14.37&#177;2.42 times at each indicated time point (<i>P</i>=0.000032, 0.0000051 and 0.0000082). Laser scanning confocal images showed ubiquitin labeled protein aggregates could not be discerned in the ischemic postconditioning group. Further study showed that ischemic postconditioning suppressed the production of carbonyl derivatives, elevated proteasome activity that was damaged by ischemia and reperfusion, increased the expression of chaperone hsp70, and maintained the quantity of chaperone hsp40.</p><p><b>Conclusion:</b> Ischemic postconditioning could rescue significantly neuronal death in the CA1 region caused by transient ischemia and reperfusion, which is closely associated with suppressing the formation of protein aggregation.</p> ]]></description>

<title>Hollow-Bone-Graft Dynamic Hip Screw Can Fix and Promote Bone Union after Femoral Neck Fracture: an Experimental Research</title> 
<description><![CDATA[ <p><b>Background:</b> Delayed bone union, nonunion or osteonecrosis often occur after femoral neck fractures in young adults. Secondary bone healing requires strong internal fixation, intramedullary pressure reduction and early functional exercise.</p><p><b>Objective:</b> To compare bone healing of femoral neck fractures treated with hollow-bone-graft dynamic hip screws (Hb-DHS) and standard dynamic hip screws (DHS) in an animal model.</p><p><b>Design</b>: Testing of specifically designed fixation devices in a pig animal model.</p><p><b>Interventions/Methods:</b> We designed Hb-DHS and DHS devices appropriate to the femoral neck and head of experimental animals and used them in eight pigs (4-month-old, male or female, 30-40 kg/each). Under anesthesia, we induced medium neck type, Garden III type femoral neck fractures in each pig with fracture gaps of 0.5 mm and then fixed each left femur with Hb-DHS and each right femur with DHS. We assessed the animals radiographically and by postmortem visual appraisal of evidence of bone healing 8 and 16 weeks postoperatively.</p><p><b>Results: </b>There were significant differences in radiographic and general findings between the Hb-DHS and DHS groups at weeks 8 and 16 postoperatively. We found statistically significant differences between the Hb-DHS and DHS groups in bone healing scores, trabecular bone volume percentage and bone mineral density as assessed on plain radiographs and computed tomography images (<i>P</i> &#60; 0.05). There were also significant differences between the Hb-DHS and DHS groups in postmortem visually assessed indicators of bone healing at both 8 and 16 weeks postoperatively.</p><p><b>Conclusions: </b>The Hb-DHS device promotes femoral neck bone union, stimulates trabecular bone formation, increases BMD and has advantages over DHS for internal fixation of femoral neck fractures. This animal experiment will contribute to developing optimal treatment for femoral neck fractures in young adults.</p> ]]></description>

<title>The Diagnostic Value of D-dimer, Procalcitonin and CRP in Acute Appendicitis</title> 
<description><![CDATA[ <p><b>BACKGROUND:</b> The early diagnosis of acute abdomen is of great importance. To date, several inflammatory markers have been used for the diagnosis of acute abdominal conditions, including acute appendicitis. The aim of this study was to evaluate the diagnostic utility of D-dimer, Procalcitonin (PCT) and C-reactive protein (CRP) measurements in the acute appendicitis.</p><p><b>METHODS:</b> This prospective study was conducted between March 1<sup>st</sup>, 2010 and July 1<sup>st</sup>, 2011. In this period, seventy-eight patients were operated with the diagnosis of acute appendicitis, and D-dimer, PCT and CRP levels of the patients were measured. The patients were grouped as phlegmonous appendicitis (Group 1), gangrenous appendicitis (Group 2), perforated appendicitis (Group 3) and negative appendectomy (Group 4) according to the surgical findings and histopathological results.</p><p><b>RESULTS:</b> Of 78 patients, 54 (69.2 %) were male and 24 (30.8 %) were female, and the mean age was 25.4 &#177; 11.1 years (range, 18 to 69 years). 66 (84.6 %) patients had increased leukocyte count (white blood cell count). The PCT values were higher than the upper normal limit in 20 (25.6%) patients, followed by D-dimer in 22 (28.2 %) patients and CRP in 54 (69.2 %) patients. The diagnostic value of leukocyte count and CRP in acute appendicitis was higher than that of the other markers, whereas leukocyte count showed very low specificity. CRP values were higher in perforated appendicitis when compared with the phlegmonous appendicitis (p&#60;0.05). However, PCT and D-dimer showed lower diagnostic values (26% and 31%, respectively).</p><p><b>CONCLUSION:</b> An increase in CRP levels alone is not sufficient to make the diagnosis of acute appendicitis. However, CRP levels may differentiate between phlegmonous appendicitis and perforated appendicitis. Due to their low sensitivity and diagnostic value, PCT and D-dimer are not better markers than CRP for the diagnosis of acute appendicitis.</p> ]]></description>

<title>Quantification of BCR-ABL mRNA in Plasma/Serum of Patients with Chronic Myelogenous Leukemia</title> 
<description><![CDATA[ <p>Quantification of tumor-associated mRNA extracted from blood cells/tissues containing tumor cells is used for evaluation of treatment efficacy or residual tumor cell burden in tumors including leukemia. However, this method using tumor cell-containing blood/tissue is difficult to evaluate the whole tumor cell burden in the body. In order to establish an efficient method to evaluate the whole tumor cell burden in the body, we tried to quantify tumor-associated mRNA existing in plasma/serum instead of leukemia cell-containing blood cells in patients with chronic myelogenous leukemia (CML) and compared the levels of BCR-ABL mRNA between plasma/serum and peripheral blood cells. mRNA of BCR-ABL, WT1 or GAPDH (control molecule) was detected by real-time RT-PCR using RNA extracted from plasma/serum of almost all the patients with CML. Copy numbers of BCR-ABL mRNA were significantly correlated between plasma/serum and peripheral blood cells. However, levels of BCR-ABL mRNA extracted from serum were low compared with those extracted with peripheral blood cells. The present findings suggest that although real-time RT-PCR of mRNA existing in plasma/serum could be used for evaluating the whole tumor cell burden in the body, it's required to establish an efficient method to quantify plasma/serum mRNA by nature without degrading during the procedure.</p> ]]></description>

<title>Three-dimensional Ultrasound Appearance of Pelvic Floor in Nulliparous Women and Pelvic Organ Prolapse Women</title> 
<description><![CDATA[ <p>The present study investigated the morphology and structure of pelvic floor in 50 nulliparous and 50 pelvic organ prolapse (POP) women using translabial three-dimensional (3D) ultrasound. The levator hiatus in POP women was significantly different from that in nullipara women. In POP women, the size of pelvic floor increased, with a circular shape, and the axis of levator hiatus departed from the normal position in 36 (72%) cases. The puborectalis was avulsed in 18 (36%) cases and the pelvic organs arranged abnormally in 23 (46%) cases. In summary, 3D ultrasound is an effective tool to detect the pelvic floor in POP women who presented with abnormalities in the morphology and structure of pelvic floor.</p> ]]></description>

<title>Molecular Mechanism of SAHA on Regulation of Autophagic Cell Death in Tamoxifen-Resistant MCF-7 Breast Cancer Cells</title> 
<description><![CDATA[ <p><b>Objective: </b>Tamoxifen is currently used for the treatment of estrogen receptor-positive breast cancer patients, but acquired resistance to tamoxifen is a critical problem in breast cancer therapy. Suberoylanilide hydroxamic acid (SAHA) is a prototype of the newly developed HDAC inhibitor. The aim of this study is to investigate the anticancer effects of SAHA in tamoxifen-resistant MCF-7 (TAMR/MCF-7) cells.</p><p><b>Methods</b>: Cytotoxicity, apoptosis and autophagic cell death induced by SAHA were studied. A TAMR/MCF-7 cells xenograft model was established to investigate the inhibitory effect of SAHA on tumor growth in vivo.</p><p><b>Results</b>: SAHA inhibited the proliferation of TAMR/MCF-7 cells in a dose-dependent manner. SAHA significantly reduced the expression of HDAC1, 2, 3, 4 and 7 and increased acetylated histone H3 and H4. Although SAHA induced G2/M phase arrest of cell cycle, apoptotic cell death was very low, which is correlated with the slight change in the activation of caspases and PARP cleavage. Interestingly, expression of the autophagic cell death markers, LC3-II and beclin-1, was significantly increased in TAMR/MCF-7 cells treated with SAHA. Autophagic cell death induced by SAHA was confirmed by acridine orange staining and transmission electron microscopy (TEM) in TAMR/MCF-7 cells. In mice bearing the TAMR/MCF-7 cell xenografts, SAHA significantly reduced the tumor growth and weight, without apparent side effects.</p><p><b>Conclusion</b>: These results suggest that SAHA can induce caspase-independent autophagic cell death rather than apoptotic cell death in TAMR/MCF-7 cells. SAHA-mediated autophagic cell death is a promising new strategy to treatment of tamoxifen-resistant human breast cancer.</p> ]]></description>

<title>Platelet Rich Fibrin (P.R.F.) in Reconstructive Surgery of Atrophied Maxillary Bones: Clinical and Histological Evaluations</title> 
<description><![CDATA[ <p><b>Introduction.</b> Maxillary bone losses often require additional regenerative procedures: as a supplement to the procedures of tissue regeneration, a platelet concentrate called PRF (<i>Platelet Rich Fibrin</i>) was tested for the first time in France by Dr. Choukroun.</p><p>Aim of the present study is to investigate, clinically and histologically, the potential use of PRF, associated with deproteinized bovine bone (Bio-Oss), as <i>grafting materials</i> in pre-implantology sinus grafting of severe maxillary atrophy, in comparison with a control group, in which only deproteinized bovine bone (Bio-Oss) was used as reconstructive material.</p><p><b>Materials and Methods.</b> 60 patients were recruited using the <i>cluster-sampling </i>method; inclusion criteria were maxillary atrophy with residual ridge &#60; 5mm. The major atrophies in selected patients involved <i>sinus-lift</i>, with a <i>second-look</i> reopening for the implant insertion phase. The used <i>grafting materials </i>were: a) Bio-Oss and b) amorphous and membranous PRF together with Bio-Oss. We performed all operations by means of piezosurgery in order to reduce trauma and to optimize the design of the operculum on the cortical bone. The reopening of the surgical area was scheduled at 3 different times.</p><p><b>Results.</b> 72 sinus lifts were performed with subsequent implants insertions.</p><p>We want to underline how the histological results proved that the samples collected after 106 days (Early protocol) with the adding of PRF were constituted by lamellar bone tissue with an interposed stroma that appeared relaxed and richly vascularized.</p><p><b>Conclusions.</b> The use of PRF and <i>piezosurgery</i> reduced the healing time, compared to the 150 days described in literature, favoring optimal bone regeneration. At 106 days, it is already possible to achieve good primary stability of endosseous implants, though lacking of functional loading.</p> ]]></description>

<title>Bone Morphogenetic Protein-9 Induces Osteogenic Differentiation of Rat Dental Follicle Stem Cells in P38 and ERK1/2 MAPK Dependent Manner</title> 
<description><![CDATA[ <p>Dental follicle stem cells are a group of cells possessing osteogenic, adipogenetic and neurogenic differentiations, but the specific mechanism underlying the multilineage differentiation remains still unclear. Great attention has been paid to bone morphogenetic protein-9 (BMP-9) due to its potent osteogenic activity. In the present study, rat dental follicle stem cells were isolated and purified, and cells of passage 3 underwent adenovirus mediated BMP-9 gene transfection to prepare dental follicle stem cells with stable BMP-9 expression. Detection of alkaline phosphatase (ALP) and calcium deposition showed dental follicle stem cells transfected with BMP-9 gene could significantly promote the osteogenesis. In addition, SB203580 and PD98059 were employed to block the p38 mitogen-activated protein kinase (p38MAPK) and extracellular signal-regulated kinase (ERK1/2), respectively. Detection of ALP and calcium deposition revealed the BMP-9 induced osteogenic differentiation of dental follicle stem cells depended on MAPK signaling pathway.</p> ]]></description>

<title>Effect of Low-Level Laser Therapy on Incorporation of Block Allografts</title> 
<description><![CDATA[ <p><b>Objective </b>To assess the effect of low-level laser therapy (LLLT) on the incorporation of deep-frozen block allografts in a rabbit model.</p><p><b>Background Data</b> Studies have shown that LLLT has beneficial effects on tissue repair and new bone formation.</p><p><b>Methods </b>Bone tissue was harvested from two rabbits, processed by deep-freezing and grafted into the calvaria of 12 animals, which were then randomly allocated into two groups: experimental (L) and control (C). Rabbits in group L were irradiated with an aluminum gallium arsenide diode laser (AlGaAs; wavelength 830 nm, 4 J/cm<sup>2</sup>), applied to four sites on the calvaria, for a total dose of 16 J/cm<sup>2</sup> per session. The total treatment dose after eight sessions was 128 J/cm<sup>2</sup>. Animals were euthanized at 35 (n = 6) or 70 days (n = 6) postoperatively.</p><p><b>Results</b> Deep-freeze-processed block allografts followed by LLLT showed incorporation at the graft-host interface, moderate bone remodeling, partial filling of osteocyte lacunae, less inflammatory infiltrate in the early postoperative period, and higher collagen deposition than the control group.</p><p><b>Conclusion</b> Optical microscopy and scanning electron microscopy showed that allograft bone processed by deep-freezing plus LLLT is suitable as an alternative for the treatment of bone defects. Use of the deep-freezing method for processing of bone grafts preserves the structural and osteoconductive characteristics of bone tissue.</p> ]]></description>

<title>Curative Resection of Hepatocellualr Carcinoma Using Modified Glissonean Pedicle Transection versus the Pringle Maneuver: A Case Control Study</title> 
<description><![CDATA[ <p><b>Objective: </b>The Glissonean pedicle transection method of liver resection has been found to shorten operative time and minimize intraoperative bleeding during liver segmentectomy. We have compared the feasibility, effectiveness, and safety of the Glissonean pedicle transection method with the Pringle maneuver in patients undergoing selective curative resection of large hepatocellualr carcinoma (HCC).</p><p><b>Methods: </b>Eligible patients with large (&#62; 5 cm) nodular HCC (n = 50) were assigned to undergo curative hepatectomy using the Glissonean pedicle transection method (n = 25) or the Pringle maneuver (n = 25). Partial interruption of the infrahepatic inferior vena cava was incorporated to further reduce bleeding from liver transection. The primary outcome measure was postoperative changes in liver function from baseline. Secondary outcomes included operating time, volume of intraoperative blood loss/transfusion, and time to resolution of ascites.</p><p><b>Results: </b>The two groups were comparable in age, sex, site and size of the liver tumor, segment or lobe intended to be resected, and liver function reserve, and the results were not significant statistically. All patients underwent successful major hepatectomies using the assigned method, with the extent of major hepatectomy comparable in the two groups (<i>P</i> = 0.832). The Glissonean approach was associated with shorter hepatic inflow interruption (30.0 &#177; 12.0 min <i>vs.</i> 45.0 &#177; 13.0 min, <i>P</i> &#60; 0.001), lower volume of blood loss (145.0 &#177; 20.0 mL <i>vs.</i> 298.0 &#177; 109.0 mL, <i>P</i> &#60; 0.001), reduced requirement for transfusion (0.0 &#177; 0.0 mL <i>vs.</i> 200.0 &#177; 109.0 mL, <i>P</i> &#60; 0.0001), and more rapid resolution of ascites (9.5 &#177; 1.2 d <i>vs.</i> 15.3 &#177; 2.4 d, <i>P</i> &#60; 0.001). Postoperative liver function measures were comparable in the two groups, and the results were not significant statistically.</p><p><b>Conclusion: </b>The Glissonean pedicle transection method is a feasible, effective, and safe technique for hepatic inflow control during the curative resection of large nodular HCCs.</p> ]]></description>

<title>Inhibitory Effects of Anthocyanins on Secretion of Helicobacter pylori CagA and VacA Toxins</title> 
<description><![CDATA[ <p>Anthocyanins have been studied as potential antimicrobial agents against <i>Helicobacter pylori</i>. We investigated whether the biosynthesis and secretion of cytotoxin-associated protein A (CagA) and vacuolating cytotoxin A (VacA) could be suppressed by anthocyanin treatment <i>in vitro</i>. <i>H. pylori</i> reference strain 60190 (CagA<sup>+</sup>/VacA<sup>+</sup>) was used in this study to investigate the inhibitory effects of anthocyanins; cyanidin 3-O-glucoside (C3G), peonidin 3-O-glucoside (Peo3G), pelargonidin 3-O-glucoside (Pel3G), and malvidin 3-O-glucoside (M3G) on expression and secretion of <i>H. pylori</i> toxins. Anthocyanins were added to bacterial cultures and Western blotting was used to determine secretion of CagA and VacA. Among them, we found that C3G inhibited secretion of CagA and VacA resulting in intracellular accumulation of CagA and VacA. C3G had no effect on <i>cag</i>A and <i>vac</i>A expression but suppressed <i>sec</i>A transcription. As SecA is involved in translocation of bacterial proteins, the down-regulation of <i>secA</i> expression by C3G offers a mechanistic explanation for the inhibition of toxin secretion. To our knowledge, this is the first report suggesting that C3G inhibits secretion of the <i>H. pylori</i> toxins CagA and VacA via suppression of <i>sec</i>A transcription.</p> ]]></description>

<title>VEGF -634C/G Genotype is Predictive of Long-term Survival after Treatment with a Definitive 5-Fluorouracil/cisplatin-based Chemoradiotherapy in Japanese Patients with Esophageal Squamous Cell Carcinoma</title> 
<description><![CDATA[ <p><b>Background:</b> Reports have been accumulating that genetic properties are predictive of clinical response after and/or toxicity during cancer chemotherapy, but little information is available concerning effects on long-term survival. In this study, 49 Japanese patients with esophageal squamous cell carcinoma (ESCC) were followed up for 5 years after treatment with a definitive 5-fluorouracil (5-FU)/cisplatin (CDDP)-based chemoradiotherapy (CRT), and the effects of genotypes of vascular endothelial growth factor (VEGF) were retrospectively revaluated in terms of prediction of long-term survival.</p><p><b>Methods:</b> A course consisted of the continuous infusion of 5-FU at 400 mg/m<sup>2</sup>/day for days 1-5 and 8-12, the infusion of CDDP at 40 mg/m<sup>2</sup>/day on days 1 and 8, and radiation at 2 Gy/day on days 1 to 5, 8 to 12, and 15 to 19, with a second course repeated after a 2-week interval. The VEGF genotypes -1498T/C, -1154G/A, -634C/G, -7C/T, 936C/T, and 1612G/A were evaluated.</p><p><b>Results:</b> The complete response (CR) rate was 46.9% (23/49). The 5-year survival rate was 42.9 % (21/49). There were 7 patients with a CR, but survival of less than 5 years. They died from myocardial infarction (N=1), sudden cardiac death after suffering from heart failure (N=1), acute myeloid leukemia that developed from myelodysplastic syndromes (N=1), factors not specified (N=2), oropharynx cancer (N=1), and tongue cancer (N=1). VEGF -634C/G had no effect on clinical response, but long-term survival depended on the genotype (p=0.033, Fisher's; p=0.038, Cochran-Armitage; p=0.079, Log-rank). The genotype frequency of 7 patients with a CR, but survival of less than 5 years was different from that for the other 42 patients (p=0.032, Fisher's). None of the other 5 genotypes evaluated affected either clinical response or survival.</p><p><b>Conclusions:</b> VEGF -634C/G is possibly predictive of long-term survival after treatment with a definitive 5-FU/CDDP-based CRT. Further clinical studies with a larger number of cases are needed to clarify the effects of this genotype.</p> ]]></description>

<title>Immune Regulation of Osteoclast Function in Postmenopausal Osteoporosis: A Critical Interdisciplinary Perspective</title> 
<description><![CDATA[ <p>Extensive studies on cross talk between immune and skeletal systems in autoimmune diseases give rise to a new discipline of 'osteoimmunolgy', which explores the molecular regulation of osteoclasts by immune system. Postmenopausal osteoporosis is recognized as a cytokine driven disease, but the mechanism that how estrogen deficiency interplaying with cytokines to stimulate bone loss remains to be elucidated. Although the effect of individual cytokines on osteoclast formation is well characterized, the major challenge is to fit a multitude of redundant pathways and cytokines into a systemic model of postmenopausal osteoporosis. This review presents current findings and hypothesis to explain estrogen deficiency-stimulated bone loss in a critical interdisciplinary perspective. To better understand the interaction between osteoclasts and immune system in postmenopausal osteoporosis, many of the lessons have been explored in animal models.</p> ]]></description>

<title>Development of a Clinically Relevant Animal Model for the Talar Osteonecrosis in Sheep</title> 
<description><![CDATA[ <p>There are a lot of reports and reviews about osteonecrosis of the talus (ONT), yet reports about the animal model of ONT to evaluate proper therapeutic approaches are rarely heard. In our study, a novel animal model was established. Pure ethanol was injected into the cancellous bone of sheep's talus. Macroscopic observation, X-ray, CT and histology were performed at two, four, 12 and 24 weeks postoperatively. It was revealed that the trabeculae of talar head began to change their structure after two weeks postoperatively compared to the normal talus. The ONT was obvious at the end of the fourth week, and their outstanding feature was the damage of trabeculae bone and formation of cavities. CT scans and pathological changes of the subjects all showed characteristics of the early stage of osteonecrosis, also the sections of the specimens confirmed necrosis of tali. By 12 weeks, the phenomenon of necrosis still existed but fibrous tissue proliferated prominently and bone reconstruction appeared in certain area. Most specimens (3/4) got late stage necrosis which presented as synarthrosis in X-ray and mass proliferation of fibrous tissue in histology at the end of 24 weeks. The novel animal model of ONT was successful, and it is inclined to deteriorate without any intervention. The study provides us a new way to evaluate various treatments on ONT in laboratory, which may eventually pave way to clinical applications.</p> ]]></description>

<title>How the Duration Period of Erythropoietin Treatment Influences the Oxidative Status of Hemodialysis Patients</title> 
<description><![CDATA[ <p><b>Background:</b> End-stage renal disease is a state of enhanced oxidative stress (OS) and hemodialysis (HD) and renal anemia further augment this disbalance. Anemia correction with erythropoietin (EPO) may improve oxidative status. However, there is no evidence of time dependent effects of EPO therapy on redox status of HD patients.</p><p><b>Objective: </b>The aim of this study was to evaluate whether the duration of EPO treatment may affect OS parameters in uremic patients.</p><p><b>Patients and methods: </b>104 HD patients and 29 healthy volunteers were included. Patients were divided into 3 groups according to the duration of EPO treatment. Forth group consisted of HD patients without EPO treatment. Plasma and erythrocyte malondialdehyde (MDA, MDA<sub>rbc</sub>), reactive carbonyl groups (RCG), plasma sulfhydryl (-SH) groups and total antioxidative capacity (TAC) levels were evaluated.</p><p><b>Results: </b>HD patients both with and without EPO treatment, showed a significant increase in all oxidative parameters without significance between EPO treated and -untreated group. The decrease in MDA and MDA<sub>rbc</sub> levels coincided with the duration of EPO treatment. A negative correlation was observed between the duration of EPO treatment and serum MDA (r=&#727;0.309, p=0.003). Increasing periods of EPO treatment were associated with decrease in RCG, without significance between EPO groups. Increase in TAC accompanied increasing durations of EPO treatment, with EPO treatment for more than 24 months causing the most striking changes (p&#60;0.05). There were no significant differences in &#727;SH levels between EPO subgroups.</p><p><b>Conclusion:</b> Our results suggest that long term administration of EPO attenuated the lipid peroxidation process and restored the levels of antioxidants.</p> ]]></description>

<title>Low-Magnitude High-Frequency Vibration Inhibits RANKL-Induced Osteoclast Differentiation of RAW264.7 Cells</title> 
<description><![CDATA[ <p>Osteoclasts are the key participants in regulation of bone mass. Low-magnitude high-frequency vibration (LMHFV) has been found to be anabolic to bone <i>in vivo</i>. This study aimed to investigate the effect of LMHFV on osteoclast differentiation <i>in vitro</i>. Murine monocyte cell line RAW264.7 cells in the presence of receptor activator of nuclear factor-kappaB ligand (RANKL) were treated with or without LMHFV at 45 Hz (0.3 g) for 15 min day<sup>&#8722;1</sup>. Tartrate resistant acid phosphatase (TRAP)-positive multinucleated cells (MNCs) and actin ring formation were evaluated. Expression of the osteoclast-specific genes, such as cathepsin K, matrix metallopeptidase-9 (MMP-9) and TRAP, were analyzed using real time-PCR. c-Fos, an osteoclast-specific transcription factor, was determined using Western blot. We found that LMHFV significantly decreased the number of RANKL-induced TRAP-positive MNCs (<i>P</i>&#60;0.01), and inhibited the actin ring formation. The mRNA expression of the cathepsin K, MMP-9 and TRAP were down-regulated by LMHFV intervention (all <i>P</i>&#60;0.001). Furthermore, LMHFV also inhibited the expression of c-Fos protein in the RANKL-treated RAW264.7 cells (<i>P</i>&#60;0.05). Our results suggest that LMHFV can inhibit the RANKL-induced osteoclast differentiation of RAW264.7 cells, which give some new insight into the anabolic effects of LMHFV on bone.</p> ]]></description>

<title>Synergistic Effects of Honey and Propolis toward Drug Multi-Resistant Staphylococcus Aureus, Escherichia Coli and Candida Albicans Isolates in Single and Polymicrobial Cultures</title> 
<description><![CDATA[ <p><b>Background</b>: Propolis and honey are natural bee products with wide range of biological and medicinal properties. The study investigated antimicrobial activity of ethyl alcohol extraction of propolis collected from Saudi Arabia (EEPS) and from Egypt (EEPE), and their synergistic effect when used with honey. Single and polymicrobial cultures of antibiotic resistant human pathogens were tested.</p><p><b>Material and methods</b>; <i>Staphylococcus aureus </i>(<i>S. aureus</i>),), <i>Escherichia coli </i>(<i>E. coli</i>) and <i>Candida albicans (C.albicans) </i>were cultured in 10-100% (v/v) honey diluted in broth, or 0.08-1.0% (weight/volume) EEPS and EEPE diluted in broth. Four types of polymicrobial cultures were prepared by culturing the isolates with each other in broth (control) and broth containing various concentrations of honey or propolis. Microbial growth was assessed on solid plate media after 24 h incubation.</p><p><b>Results; </b>EEPS and EEPE inhibited antibiotic resistant <i>E.coli, </i>and <i>S.aureus,</i> and <i>C.albicans</i> in single and polymicrobial cultures<i>. S.aureus</i> became more susceptible when it was cultured with <i>E.coli</i> or <i>C.albicans</i> or when all cultured together. <i>C.albicans</i> became more susceptible when it was cultured with <i>S.aureus</i> or with <i>E.coli</i> and <i>S. aureus</i> together. The presence of ethyl alcohol or honey potentiated antimicrobial effect of propolis toward entire microbes tested in single or polymicrobial cultures. EEPS had lower MIC toward <i>E.coli</i> and <i>C.albicans</i> than EEPE. When propolis was mixed with honey, EEPS showed lower MIC than EEPE. In addition, honey showed lower MIC toward entire microbes when mixed with EEPS than when it was mixed with EEPE.</p><p><b>Conclusion</b>; 1) propolis prevents the growth of the microorganisms in single and mixed microbial cultures, and has synergistic effect when used with honey or ethyl alcohol, 2) the antimicrobial property of propolis varies with geographical origin, and 3) this study will pave the way to isolate active ingredients from honey and propolis to be further tested individually or in combination against human resistant infections.</p> ]]></description>

<title>Effects of Smokeless Tobacco &#8220;Maras Powder&#8221; Use on Nitric Oxide and Cardiovascular Risk Parameters</title> 
<description><![CDATA[ <p><b>Background:</b> Smokeless tobacco use is common in various parts of the world. In Turkey a type of smokeless tobacco called &#8220;Maras powder&#8221; is widely used in southeastern region. Smoking is known to have an adverse effect on nitric oxide and cardiovascular risk factors. The aim of this study was to evaluate whether there is difference between the effects of Maras powder and cigarette smoking on the cardiovascular risk factors and nitric oxide levels.</p><p><b>Methods:</b> In the study, participants were 48 Maras powder users, 50 cigarette smokers and 45 nontobacco user subjects. Blood samples were collected and hematological parameters and lipid parameters were measured. Plasma Nitric oxide level was also detected by using the Griess method.</p><p><b>Results:</b> Plasma total cholesterol, LDL-cholesterol, triglyceride levels were significantly higher in Maras powder and cigarette smokers group than in the nontobacco user group (p&#60;0.001). Plasma HDL-cholesterol levels were significantly lower in Maras powder and cigarette smokers group than in the nontobacco user group (p&#60;0.001). Plasma Nitric oxide levels were found significantly lower in Maras powder and cigarette smokers group compared to the nontobacco user group (4.9&#177;0.9 &#181;mol/l, 4.8&#177;1 &#181;mol/l, 9.4&#177;3.4 &#181;mol/l, respectively, p&#60;0.001) whereas there was no significant difference between the Maras powder and cigarette smokers group. In multivariate logistic regression model, cigarette smoking (Odds ratio=17.832, p&#60;0.001), Maras powder usage (Odds ratio=12.311, p=0.002) and mean platelet volume (Odds ratio=1.425, p=0.030) remained independently associated with lower Nitric oxide levels.</p><p><b>Conclusion:</b> We conclude that Maras powder has similar adverse effects on nitric oxide level and cardiovascular risk parameters and thereby it appears to be harmful as cigarette smoking.</p> ]]></description>

<title>Plasma Brain-derived Neurotrophic Factor in Hemodialysis Patients</title> 
<description><![CDATA[ <p><b>Objective:</b> Brain-derived neurotrophic factor (BDNF) is a neurotrophin which modulates neuronal survival and proliferation. Recently, plasma BDNF is associated with inflammatory conditions. The present study was to investigate the changes of the plasma BDNF level in hemodialysis patients and to evaluate the relationship between the plasma BDNF and uremic inflammation.</p><p><b>Method:</b> We measured the plasma BDNF, serum IL-2, IL-4, IFN-&#947; and TNF-&#945; in hemodialysis patients and control subjects. In addition, we investigated the associations of the plasma BDNF with clinical or biochemical parameters.</p><p><b>Results:</b> The plasma BDNF level was significantly higher in hemodialysis patients than in the control subjects (median, 312.3 vs. 630.3 pg/ml, <i>p</i> &#60; 0.05). In subgroup analysis, hemodialysis patients with diabetes showed higher values of the plasma BDNF than the patients without diabetes. However, there were no significant differences in age and gender subgroups of the hemodialysis patients. The logBDNF was positively correlated with hs-CRP and IFN-&#947;, and negatively correlated with serum albumin. In multivariate regression analysis, the logBDNF was independently associated with the presence of diabetes (&#946;-coefficient = 0.399, p = 0.041) and IFN-&#947; (&#946;-coefficient = 0.538, p = 0.003).</p><p><b>Conclusion:</b> The plasma BDNF may increase in hemodialysis patients, and more prominently in the patients with diabetes. Furthermore, the plasma BDNF might reflect inflammatory condition in hemodialysis patients.</p> ]]></description>

<title>Non-Stimulation Needle with External Indwelling Cannula for Brachial Plexus Block and Pain Management in 62 Patients Undergoing Upper-Limb Surgery</title> 
<description><![CDATA[ <p><b>Objective:</b> To investigate the feasibility of a non-stimulation needle with an external indwelling cannula for upper-limb surgery and acute postoperative pain management. <b>Methods: </b>62 patients undergoing either scheduled or emergency upper-limb surgery received brachial plexus block of modified interscalene or axillary brachial and then postoperative patient-controlled analgesia (PCA) with local analgesics using a specially designed non-stimulation needle with an external indwelling cannula. The outcome measurements included anesthetic effect, acute or chronic complications, postoperative analgesic effect and patient's satisfaction. <b>Results:</b> The success rate of anesthesia was 96.8%. The single attempt placement with the external indwelling cannula was achieved in 85.2% of patients with axillary brachial plexus block and 78.8% with modified interscalene brachial plexus block. The incidence of severe intoxication was 3.7% with axillary brachial plexus block and 3.0% with modified interscalene brachial plexus block. No hematoma at the injection site, Horner's syndrome, hoarseness or dyspnea was observed. Postoperative analgesic effect was achieved in 100% and activities were slightly lowered in 91.7%. The incidence of nausea and vomit was 8.3%; patient's satisfaction was 9.1 on a 10-point scale system. Infection, nerve injury and respiratory depression were absent during the catheter indwelling. The indwelling time of external indwelling cannula was 30.5 h on average. There was no nerve injury related complication after withdrawing the external indwelling catheter. <b>Conclusions: </b>Brachial plexus block using a non-stimulation needle with an external indwelling cannula has favorable intra-operative anesthetic benefit and provides an excellent postoperative analgesic outcome. The low incidence of complications and favorable patient's satisfaction suggest that non-stimulation needle with an external indwelling cannula is a useful and safe anesthetic tool in brachial nerve block and acute postoperative pain management.</p> ]]></description>

<title>Multiple-, But Not Single-, Dose of Parecoxib Reduces Shoulder Pain after Gynecologic Laparoscopy</title> 
<description><![CDATA[ <p>Background: The aim of this study was to investigate effect of single- and multiple-dose of parecoxib on shoulder pain after gynecologic laparoscopy.</p><p>Methods: 126 patients requiring elective gynecologic laparoscopy were randomly allocated to three groups. Group M (multiple-dose): receiving parecoxib 40mg at 30min before the end of surgery, at 8 and 20hr after surgery, respectively; Group S (single-dose): receiving parecoxib 40mg at 30min before the end of surgery and normal saline at the corresponding time points; Group C (control): receiving normal saline at the same three time points. The shoulder pain was evaluated, both at rest and with motion, at postoperative 6, 24 and 48hr. The impact of shoulder pain on patients' recovery (activity, mood, walking and sleep) was also evaluated. Meanwhile, rescue analgesics and complications were recorded.</p><p>Results: The overall incidence of shoulder pain in group M (37.5%) was lower than that in group C (61.9%) (difference=-24.4%; 95% CI: 3.4&#126;45.4%; P=0.023). Whereas, single-dose regimen (61.0%) showed no significant reduction (difference with control=-0.9%; 95% CI: -21.9&#126;20.0%; P=0.931). Moreover, multiple-dose regimen reduced the maximal intensity of shoulder pain and the impact for activity and mood in comparison to the control. Multiple-dose of parecoxib decreased the consumption of rescue analgesics. The complications were similar among all groups and no severe complications were observed.</p><p>Conclusions: Multiple-, but not single-, dose of parecoxib may attenuate the incidence and intensity of shoulder pain and thereby improve patients' quality of recovery following gynecologic laparoscopy.</p> ]]></description>

<title>THRB Genetic Polymorphisms Can Predict Severe Myelotoxicity after Definitive Chemoradiotherapy in Patients with Esophageal Squamous Cell Carcinoma</title> 
<description><![CDATA[ <p><b>Objective: </b>Chemotherapy-related toxicities are difficult to predict before treatment. In this study, we investigated whether <i>thyroid hormone receptor beta </i>(<i>THRB</i>) genetic polymorphisms can serve as a potential biomarker in patients with esophageal squamous cell carcinoma (ESCC).</p><p><b>Methods: </b>Forty-nine Japanese patients with ESCC who received a definitive chemoradiotherapy (CRT) with 5-fluorouracil and cisplatin in conjunction with concurrent irradiation were retrospectively analyzed. Severe acute toxicities, including leukopenia, stomatitis, and cheilitis, were evaluated according to 6 single nucleotide polymorphisms (SNPs) in the gene; the intronic SNPs of rs7635707 G/T, rs6787255 A/C, rs9812034 G/T, and rs9310738 C/T and the SNPs in the 3&#8242;-untranslated region (3&#8242;-UTR) of rs844107 C/T and rs1349265 G/A.</p><p><b>Results</b>: Distribution of the 4 intronic SNPs, but not the 2 SNPs in the 3&#8242;-UTR, showed a significant difference between patients with and without severe acute leukopenia. Stomatitis and cheilitis were not associated with any of the 6 analyzed SNPs. Frequency of haplotype of the 4 intronic SNPs reached approximately 97% with the 2 major haplotypes G-A-G-C (73.4%) and T-C-T-T (23.5%).</p><p><b>Conclusions: </b><i>THRB</i> intronic SNPs can provide useful information on CRT-related severe myelotoxicity in patients with ESCC. Future studies will be needed to confirm these findings.</p> ]]></description>

<title>A Two-Step Control of Secondary Splenic Pedicles Using Ligasure during Laparoscopic Splenectomy</title> 
<description><![CDATA[ <p><b>Objective: </b>We modified the LigaSure vessel sealing into a two-step technique without using Endo-GIA stapler for the secondary splenic pedicle control in laparoscopic splenectomy (LS). This study evaluated the efficacy and safety outcomes of this technique.</p><p><b>Methods: </b>Patients (n = 105) scheduled for elective LS were consecutively and prospectively enrolled, including 24 males and 81 females, with a mean age of 43.6 (range 11-75) years. Following the mobilization of the spleen, the splenic inflow was interrupted by applying a Hem-o-lock clip. LigaSure was used to seal and transect the secondary splenic pedicles adjacent to the pancreatic tail and subsequently in proximity to the spleen.</p><p><b>Results: </b>Of 105 patients, 103 patients (98.1%) underwent successful LS, whereas two patients (1.9%) required the conversion to laparotomy. The mean operative time was 100 min, whilst the mean volume of blood loss was 500 mL. No clinically significant morbidities or mortality occurred following LS. An average of 8,000 RMB (range: 6900 to 9000; 1 USD = 6.5 RMB) was saved by using this two-step technique.</p><p><b>Conclusion:</b> Secondary splenic pedicles can be successfully controlled in LS by using a two-step technique with the LigaSure vessel sealing system in an economically favorable way.</p> ]]></description>

<description><![CDATA[ <p><b>Background: </b>The purpose of this research is to discover whether measurement of cervical length and cervical volume at term is helpful in predicting the onset of labor in VBAC candidates.</p><p><b>Methods: </b>Transvaginal sonographic evaluations of the cervixes of pregnant women who desired to undergo VBAC were performed between 36 - 40 weeks gestation. Clinical information such as labor onset time, gestational age at delivery and delivery mode was gathered from medical records.</p><p><b>Results: </b>A total of 514 pregnant women participated in this study. Cervical length was significantly longer in the group that delivered 7 days or more after measurement than in the group that delivered within 7 days of measurement (43&#177;0.77 cm vs. 2.99&#177;0.72 cm, <i>p</i>&#60; 0.001). Cervical volume was significantly larger in the group that delivered at and after 7 days than in the group that delivered within 7 days (29.21&#177;11.62 cm<sup>3</sup> vs. 34.07&#177;13.41 cm<sup>3</sup>, <i>p</i>=0.014). The cervical length ROC curve was significantly more predictive than the cervical volume ROC curve (AUC: 0.711 vs 0.594, <i>p</i>= 0.001). There were no significant differences between the combined cervical length/volume ROC curve and the cervical length ROC curve alone (<i>p</i>= 0.565). The AUC of the cervical length ROC curve to predict postterm pregnancy was 0.729.</p><p><b>Conclusion: </b>Measuring cervical length is helpful in predicting the onset of spontaneous labor within 7 days and posterm delivery in VBAC candidates.</p> ]]></description>

<title>Age- and Gender Dependent Association between Components of Metabolic Syndrome and Subclinical Arterial Stiffness in a Chinese Population</title> 
<description><![CDATA[ <p><b>Background: </b>The aim of this study was to estimate the relationship between arterial stiffness and components of metabolic syndrome (MetS) in different age- and gender groups.</p><p><b>Methods: </b>A total of 12,900 Chinese adults aged 20-79 years were recruited and stratified on the basis of gender and age. All participants underwent the measurement of waist circumference, blood pressure (BP), brachial-ankle pulse wave velocity (baPWV; an indicator of arterial stiffness), and blood chemistry. Multiple linear regression analysis was performed to evaluate the relationship between baPWV and above variables, to determine the relative influence of each component of MetS on baPWV.</p><p><b>Results: </b>The prevalence of metabolic disorders except for low high-density lipoprotein cholesterol (HDL-C) was much higher in men than in women. All participants with MetS or any component of MetS except for low HDL-C had higher baPWV. BP was positively correlated with baPWV in all groups, while HDL-C was not correlated with baPWV in any groups. In addition, fasting glucose was related to baPWV in middle-aged adults and the elderly. Waist circumference had a positive association with baPWV in middle-aged adults and young men, triglyceride levels showed a significant correlation with baPWV in middle-aged women and young men. Of the MetS components, elevated BP was the strongest predictor of baPWV.</p><p><b>Conclusion: </b>The prevalence of metabolic disorders and the association between baPWV and metabolic variables are dependent on age and gender. Different components of MetS exert distinct impacts on the baPWV in different age- and gender groups, with BP being the strongest predictor. It is suggested that age and gender should be taken into accounted in the management of MetS aiming to reduce subsequent complications.</p> ]]></description>

<title>Clinical Effect of Acute Complete Acromioclavicular Joint Dislocation Treated with Micro-Movable and Anatomical Acromioclavicular Plate</title> 
<description><![CDATA[ <p><b>Objectives:</b> We evaluated the long-term clinical results of acute complete acromioclavicular dislocations treated with micro-movable and anatomical acromioclavicular plate.</p><p><b>Methods:</b> Open reduction and internal fixation was performed using the MAAP in 16 patients (10 males, 6 females; mean age 36 years; range16 to 63 years) with acute complete acromioclavicular joint dislocation. Radiographic evaluations were routinely conducted every 3 weeks until 3 months postoperatively. The MAAP were removed under local anesthesia after 3 months postoperatively. We evaluated the functional results by using the constant scoring system and radiological results in the last follow-up time. The mean follow up was 26 months (range 16 to 38 months).</p><p><b>Results:</b> The mean Constant score was 94 (range, 78 to 100). The results were excellent in 12 patients (75.0%), good in 3 patients (18.8%) and satisfactory in 1patient (6.2%). Three patients with scores of 80 to 90 had mild pain during activity, but have not affected the shoulder range of motion. One patient has both some pain and limited range of motion of shoulder joint. All patients but one have returned to their preoperative work without any limitations. Compared to the contralateral side, radiography showed anatomical reposition in the vertical plane in 14 cases, slight loss of reduction in 2 older patients.</p><p><b>Conclusion</b>: We recommend the MAAP fixation for surgical treatment of acute complete acromioclavicular joint dislocation as it could provide satisfactory shoulder functions and clinical results, with lower complication rate. However, it is necessary to continue to observe the clinical effects of this fixation technique.</p> ]]></description>

<title>The SCARB1 rs5888 SNP and Serum Lipid Levels in the Guangxi Mulao and Han Populations</title> 
<description><![CDATA[ <p><b>Backgroud</b>: The associations of scavenger receptor class B type 1 (SCARB1) rs5888 single nucleotide polymorphism (SNP) and serum lipid levels are inconsistant among diverse ethnic populations. The present study was undertaken to detect the association of rs5888 SNP and serum lipid levels in the Guangxi Mulao and Han populations.</p><p><b>Methods</b>: Genotypes of the SCARB1 rs5888 SNP in 801 subjects of Mulao and 807 subjects of Han Chinese were determined by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing.</p><p><b>Results</b>: Serum apolipoprotein (Apo) B levels and the T allelic frequency were higher in Mulao than in Han. Serum high-density lipoprotein cholesterol (HDL-C) levels in Mulao were different among the genotypes, the subjects with TT genotype had lower HDL-C levels than the subjects with CC or CT genotype in female (<i>P </i>&#60; 0.05). For the Han population, serum triglyceride (TG), HDL-C, ApoAI, ApoB levels and the ratio of ApoAI to ApoB in males were different among the genotypes, the T allele carriers had lower serum HDL-C, ApoAI levels and ApoAI/ApoB ratio and higher serum ApoB levels than the T allele noncarriers (<i>P</i> &#60; 0.05 for all), the subjects with TT genotype had higher serum TG levels than the subjects with CC or CT genotype. Serum HDL-C levels in Mulao females and serum HDL-C, ApoAI, ApoB levels and the ApoAI/ApoB ratio in Han males were correlated with genotypes by the multiple linear regression analysis. Serum lipid parameters were also influenced by genotype-environmental interactions in Han but not in Mulao populations.</p><p><b>Conclusions</b>: These results suggest that the rs5888 SNP is associated with serum HDL-C levels in Mulao females, and TG, HDL-C, ApoAI, ApoB levels and the ApoAI/ApoB ratio in Han males. The differences in serum ApoB levels between the two ethnic groups might partially attribute to different SCARB1 genotype-environmental interactions.</p> ]]></description>

<title>Gross Total Resection of Glioma with the Intraoperative Fluorescence-guidance of Fluorescein Sodium</title> 
<description><![CDATA[ <p><b><i>Objective</i>.</b> High dose fluorescein sodium has been utilized for fluorescence-guided tumor resection with conflicting reports on the efficacy of this procedure. The aim of this study was to reevaluate the utility and clinical limitations of using fluorescein sodium for the treatment and resection of glioma brain tumors.</p><p><b><i>Methods.</i></b> Patients diagnosed with glioma were divided into two groups with a total of 22 patients enrolled in the study: 1) the study group (n=10), patients that received intravenous injection of fluorescein sodium and 2) the control group (n=12), patients that did not receive injections during surgical resection. Quality of life was evaluated according to Karnofsky Performance Scale (KPS) score and neurological status. Fluorescein sodium was intravenously injected at a dose of 15-20mg/kg of body weight. Glioma resection was evaluated preoperative and postoperatively with enhanced Magnetic Resonance Imaging (MRI).</p><p><b><i>Results.</i></b> Significant differences in the gross total resection (GTR) rates were observed between the two patient groups (Fisher's Exact Test <i>p=0.047</i>). Progressive free survival was significantly longer in the study group (Student's T-Test <i>p</i>=0.033) as well as in the GTR group (Student's T-Test <i>p</i>=0.0001) compared to the control and non-GTR groups, respectively. Three patients in the study group and four patients in the control group had transient neurological deterioration. One patient in the control group had permanent hemiplegia.</p><p><b><i>Conclusion.</i></b> The intraoperative utility of using fluorescein sodium can significantly increase the GTR rate without obvious deterioration. In addition, we find that it is better to apply the fluorescein sodium in the cases with BBB (blood-brain barrier) disruption, which had been enhanced in preoperative MRI.</p> ]]></description>

<title>Monitoring Reasons for Encounter via an Electronic Patient Record System: the Case of a Rural Practice Initiative</title> 
<description><![CDATA[ <p>The objective of this brief communication was to tabulate common reasons for encounter in a Greek rural general practice, as result of a recently adopted electronic patient record (EPR) application. Twenty encounter reasons accounted for 3,797 visits (61% of all patient encounters), whereas 565 other reasons accounted for the remaining 2,429 visits (39%). Number one reason for encounter was health maintenance or disease prevention seeking services, including screening examinations for malignancies, immunization and provision of medical opinion reports. Hypertension, lipid disorder and ischemic heart disease without angina were among the most common reasons for seeking care. A strengths/weaknesses/opportunities/threats (SWOT) analysis on the key role of an EPR system in collecting data from rural and remote primary health care settings is also presented.</p> ]]></description>

<title>Correlation between the Digital Cervicography and Pathological Diagnosis Performed at Private Clinics in Korea</title> 
<description><![CDATA[ <p>Objective: To evaluate the correlation tendency between abnormal findings of digital cervicography and cervical pathology at private clinics in Korea.</p><p>Methods: Abnormal finding of digital cervicography performed at private clinics in Korea between January 1, 2010 and May 31, 2012 were analysed retrospectively. The patient's age, abnormal findings of digital cervicography, cervical cytology, human papillomaviru (HPV) test and cervical pathology were investigated and the rate of agreement between abnormal finding of digital cervicography and cervical pathology results was calculated. Abnormal findings of digital cervicography were divided into 4 categories: atypical, compatible with CIN1, compatible with CIN2/3 and compatible with cancer.</p><p>Results: The study group was composed of 1547 women with a mean (range) age of 37.4 (14-91 years). The agreement rate between abnormal findings of digital cervicography and cervical pathology was 52.0% in &#8220;compatible with CIN1&#8221;, 78.9% in &#8220;compatible with CIN2/3&#8221;, and 90.2% in &#8220;compatible with cancer&#8221;.</p><p>Conclusions: Abnormal findings of digital cervicography were highly concordant with cervical intraepithelial neoplasia (CIN) and cancer examined at outpatient clinics in Korea. Therefore, abnormal interpretations of digital cervicography can be used as an excellent auxiliary technique with cervical cytology for CIN and cancer.</p> ]]></description>

<title>Aberrant TRPV1 Expression in Heat Hyperalgesia Associated with Trigeminal Neuropathic Pain</title> 
<description><![CDATA[ <p>Trigeminal neuropathic pain is a facial pain syndrome associated with trigeminal nerve injury. However, the mechanism of trigeminal neuropathic pain is poorly understood. This study aimed to determine the role of transient receptor potential vanilloid 1 (TRPV1) in heat hyperalgesia in a trigeminal neuropathic pain model. We evaluated nociceptive responses to mechanical and heat stimuli using a partial infraorbital nerve ligation (pIONL) model. Withdrawal responses to mechanical and heat stimuli to vibrissal pads (VP) were assessed using von Frey filaments and a thermal stimulator equipped with a heat probe, respectively. Changes in withdrawal responses were measured after subcutaneous injection of the TRP channel antagonist capsazepine. In addition, the expression of TRPV1 in the trigeminal ganglia was examined. Mechanical allodynia and heat hyperalgesia were observed in VP by pIONL. Capsazepine suppressed heat hyperalgesia but not mechanical allodynia. The number of TRPV1-positive neurons in the trigeminal ganglia was significantly increased in the large-diameter-cell group. These results suggest that TRPV1 plays an important role in the heat hyperalgesia observed in the pIONL model.</p> ]]></description>

<title>The Role of Invasive and Non-Invasive Procedures in Diagnosing Fever of Unknown Origin</title> 
<description><![CDATA[ <p><b>Background:</b> The etiology of fever of unknown origin has changed because of the recent advances in and widespread use of invasive and non-invasive diagnostic tools. However, undiagnosed patients still constitute a significant number.</p><p><b>Objective:</b> To determine the etiological distribution and role of non-invasive and invasive diagnostic tools in the diagnosis of fever of unknown origin.</p><p><b>Materials &#38; Methods:</b> One hundred patients who were hospitalized between June 2001 and 2009 with a fever of unknown origin were included in this study. Clinical and laboratory data were collected from the patients' medical records retrospectively.</p><p><b>Results: </b>Fifty three percent of the patients were male, with a mean age of 45 years. The etiology of fever was determined to be infectious diseases in 26, collagen vascular diseases in 38, neoplastic diseases in 14, miscellaneous in 2 and undiagnosed in 20 patients. When the etiologic distribution was analyzed over time, it was noted that the rate of infectious diseases decreased, whereas the rate of rheumatological and undiagnosed diseases relatively increased because of the advances in imaging and microbiological studies. Seventy patients had a definitive diagnosis, whereas 10 patients had a possible diagnosis. The diagnoses were established based on clinical features and non-invasive tests for 61% of the patients and diagnostic benefit was obtained for 49% of the patients undergoing invasive tests. Biopsy procedures contributed a rate of 42% to diagnoses in patients who received biopsies.</p><p><b>Conclusion:</b> Clinical features (such as detailed medical history-taking and physical examination) may contribute to diagnoses, particularly in cases of collagen vascular diseases. Imaging studies exhibit certain pathologies that guide invasive studies. Biopsy procedures contribute greatly to diagnoses, particularly for malignancies and infectious diseases that are not diagnosed by non-invasive procedures.</p> ]]></description>

<title>What Do We Need beyond Hemoglobin A1c to Get the Complete Picture of Glycemia in People with Diabetes?</title> 
<description><![CDATA[ <p>Hemoglobin A1c (HbA1c) is currently the most commonly used marker for the determination of the glycemic status in people with diabetes and it is frequently used to guide therapy and especially medical treatment of people with diabetes. The measurement of HbA1c has reached a high level of analytical quality and, therefore, this biomarker is currently also suggested to be used for the diagnosis of diabetes. Nevertheless, it is crucial for people with diabetes and their treating physicians to be aware of possible interferences during its measurement as well as physiological or pathological factors that contribute to the HbA1c concentration without being related to glycemia, which are discussed in this review. We performed a comprehensive review of the literature based on PubMed searches on HbA1c in the treatment and diagnosis of diabetes including its most relevant limitations, glycemic variability and self-monitoring of blood glucose (SMBG). Although the high analytical quality of the HbA1c test is widely acknowledged, the clinical relevance of this marker regarding risk reduction of cardiovascular morbidity and mortality is still under debate. In this respect, we argue that glycemic variability as a further risk factor should deserve more attention in the treatment of diabetes.</p> ]]></description>

<title>Intracranial Pressure Response to Non-Penetrating Ballistic Impact: An Experimental Study Using a Pig Physical Head Model and Live Pigs</title> 
<description><![CDATA[ <p>This study was conducted to characterize the intracranial pressure response to non-penetrating ballistic impact using a &#34;scalp-skull-brain&#34; pig physical head model and live pigs. Forty-eight ballistic tests targeting the physical head model and anesthetized pigs protected by aramid plates were conducted with standard 9 mm bullets at low (279-297 m/s), moderate (350-372 m/s), and high (409-436 m/s) velocities. Intracranial pressure responses were recorded with pressure sensors embedded in similar brain locations in the physical head model and the anesthetized pigs. Three parameters of intracranial pressure were determined from the measured data: intracranial maximum pressure (P<sub>max</sub>), intracranial maximum pressure impulse (PI<sub>max</sub>), and the duration of the first positive phase (PPD). The intracranial pressure waves exhibited blast-like characteristics for both the physical model and l live pigs. Of all three parameters, P<sub>max</sub> is most sensitive to impact velocity, with means of 126 kPa (219 kPa), 178 kPa (474 kPa), and 241 kPa (751 kPa) for the physical model (live pigs) for low, moderate, and high impact velocities, respectively. The mean PPD becomes increasingly short as the impact velocity increases, whereas PI<sub>max</sub> shows the opposite trend. Although the pressure parameters of the physical model were much lower than those of the live pigs, good correlations between the physical model and the live pigs for the three pressure parameters, especially P<sub>max</sub>, were found using linear regression. This investigation suggests that P<sub>max</sub> is a preferred parameter for predicting the severity of the brain injury resulting from behind armor blunt trauma (BABT).</p> ]]></description>

<title>Effect of Different Irrigating Solutions and Endodontic Sealers on Bond Strength of the Dentin - Post Interface with and without Defects</title> 
<description><![CDATA[ <p><b>Aims.</b> To investigate how the interfacial shear strength of the dentin - post interface with and without defects changes for different combinations irrigant/sealer.</p><p><b>Methods.</b> In forty human decoronated and instrumented teeth, fibreglass posts were inserted. The obtained root segments were randomly assigned to four different groups according to the irrigant adopted and the cement used to seal the root canal. The root segments were processed for metyl-methacrylate embedding. Serial sections were obtained and submitted to histomorphometric analyses in order to observe any defect of adhesion at the dentin - post interface and to measure the defects' dimension. The serial sections were also submitted to micro-push-out test. The measured shear strength values were subjected to statistical analysis by one-way ANOVA. The values of bond strength determined for the defective samples were correlated with the dimension of the defects. Finite element models were built to interpret and corroborate the experimental findings.</p><p><b>Results.</b> ANOVA showed that the generic combination irrigant/sealer does not affect the interfacial shear strength values. The bond strength of the samples without defects was averagely twice as large as that of the defective samples. The defects occupying more than 12 % of the total transverse section area of the endodontic cement layer led to a reduction of the bond strength of about 70 %. The predictions of the finite element models were in agreement with the experimental results.</p><p><b>Conclusion.</b> Defects occupying less than 2 % of the total transverse section area of the cement layer were shown to be acceptable as they have rather negligible effects on the shear strength values. Technologies/protocols should be developed to minimize the number and the size of the defects.</p> ]]></description>

<title>Decisive Indicator for Gastrointestinal Workup in Anemic Patients with Nondialysis Chronic Kidney Disease</title> 
<description><![CDATA[ <p><b>Background:</b> Anemia and iron deficiency are universal problems in patients with chronic kidney disease (CKD). However, decisive indicator to guide the further gastrointestinal (GI) workup has not been determined.</p><p><b>Methods:</b> We included 104 anemic patients with nondialysis-dependent CKD stages 3-5 (38 patients at stage 3, 26 patients at stage 4, and 40 patients at stage 5). Hemoglobin, serum ferritin, transferrin saturation (TSAT), mean corpuscular volume (MCV), and corrected reticulocyte count data were assessed to evaluate diagnostic utility for bleeding-related GI lesions, which were identified by esophagogastroduodenoscopy and colonoscopy.</p><p><b>Results:</b> Bleeding-related GI lesions were found in 55 (52.9%) patients, and patients with stage 5 CKD had a higher prevalence of gastric lesions than patients with CKD stage 3 or 4 (all p &#60; 0.05). The areas under the receiver operating characteristic curves used to predict bleeding-related lesions were 0.69 for TSAT (p = 0.002) and 0.61 for serum ferritin (p = 0.085). The sensitivity and specificity of a cutoff value for TSAT &#60; 20% were 0.59 and 0.74, respectively. Hemoglobin, MCV, and corrected reticulocyte levels had no significant diagnostic utility. On multivariable logistic regression, the chance of GI lesions increased by 6% for each 1% reduction in TSAT and increased 4.1-fold for patients with CKD stage 5 (all p &#60; 0.05).</p><p><b>Conclusions:</b> TSAT is a useful indicator for determining the GI workup in anemic patients with nondialysis-dependent CKD stages 3-5. Stage 5 CKD is independently associated with bleeding-related lesions and TSAT should be used cautiously in these patients.</p> ]]></description>

<title>Haematoporphyrin Based Photodynamic Therapy Combined with Hyperthermia Provided Effective Therapeutic Vaccine Effect against Colon Cancer Growth in Mice</title> 
<description><![CDATA[ <p>Photodynamic therapy (PDT) has become an attractive option used in tumor treatment via its direct tumoricidal activities or its immune-boosting activities. On the other hand, heat shock protein 70 has been found to be largely associated with the establishment of anti-tumor activities offered by hyperthermia treated tumor cells. In the present study, we found that injection of tumor-bearing mice with colon cancer cell line CT-26 treated with haematoporphyrin based photodynamic therapy (hematoporphyrin monomethyl ether based PDT, HMME-PDT) together with hyperthermia demonstrated the most effective therapeutic effects against tumor growth, followed by cells treated by hyperthermia alone. CT-26 cells treated only with HMME-PDT failed to provide any therapeutic effects, although significant cell death was induced by HMME-PDT. Compared to hyperthermia treatment, HMME-PDT induced more efficient surface localization of HSP70 on CT-26 cells which correlated with efficient activation of cytolytic CD8 T cells and with effective anti-tumor responses. Thus, our study demonstrated that the surface expression of HSP70 may play a more important role than the total expression or release of this molecule in the activation of immune responses. And our study offered a novel modified PDT approach to the treatment of tumor cells intrinsically low on HSP70 expression.</p> ]]></description>

<title>Pre-operative Serum Alkaline Phosphatase as a Predictor for Hypocalcemia Post-Parathyroid Adenectomy</title> 
<description><![CDATA[ <p><b><i>Background</i></b><i>.</i> Post-operative hypocalcemia (POH) may complicate parathyroidectomy for primary hyperparathyroidism. This study investigates the relationship between POH and pre-operative risk factors to identify a simple method to predict POH risk.</p><p><b><i>Methods.</i></b> Retrospective data on risk factors for 29 patients was collected for age, pre-operative serum calcium, alkaline phosphatase (ALP), parathyroid hormone (PTH), adenoma size, gender, and bisphosphonate pre-treatment. These were screened to exclude those with small effect sizes, and analyzed using Univariate General Linear Modeling (GLM) with trough serum calcium (TSC) as the dependent variable. The regression function of the significant variables against TSC was plotted with 95% CI fit lines. The cut-off regression value was read from the lower fit line for the threshold TSC of 2.0 mmol/L.</p><p><b><i>Results.</i></b> After screening, log-transformed age (r=0.600), ALP (r=-0.415), and PTH (r=-0.433) were entered into GLM analysis, which showed that only ALP was significant (p=0.016 Eta-squared=0.220). The GLM model had a partial Eta-squared of 0.559 with 98% observed power. The plot of TSC against log-ALP gave an ALP cut-off of 340 U/L.</p><p><b><i>Conclusions.</i></b> The study shows that there is a strong relationship between ALP and TSC, and that patients with a pre-operative ALP less than 340 U/L are unlikely to have symptomatic POH (100% sensitivity, 95% specificity). While vitamin D was not analyzed in this study, the ALP cut-off is conservative and should still screen out cases with severe vitamin D deficiency. We therefore recommend that pre-operative ALP be utilized to complement clinical protocols for POH management in parathyroid adenomectomy patients.</p> ]]></description>

<title>CD44+/CD105+ Human Amniotic Fluid Mesenchymal Stem Cells Survive and Proliferate in the Ovary Long-Term in a Mouse Model of Chemotherapy-Induced Premature Ovarian Failure</title> 
<description><![CDATA[ <p>Objectives: Stem cell transplantation has been reported to rescue ovarian function in a preclinical mouse model of chemotherapy-induced premature ovarian failure (POF); however, maintaining the survival and self-renewal of transplanted seed cells in ovarian tissues over the long-term remains a troublesome issue. In this study we aimed to determine whether the CD44+/CD105+ human amniotic fluid cell (HuAFCs) subpopulation represent potential seed cells for stem cell transplantation treatments in POF. Materials and methods: The CD44+/CD105+ subpopulation were isolated from HuAFCs, cultured in vitro, and injected into a cyclophosphamide-induced mouse model of POF. Results: Under continuous subculture <i>in vitro, </i>CD44+/CD105+ cells proliferated rapidly and expressed high levels of the proliferative markers Ki67 and survivin, as well as high levels of a number of mesenchymal stem cell biomarkers. Moreover, when red fluorescence protein (RFP)-transduced CD44+/CD105+ HuAFCs were transplanted into the ovaries of POF mice, the cells could be detected by fluorescence microscopy up to three weeks after injection. Furthermore, the BrdUrd incorporation assay and immunofluorescent staining demonstrated that CD44+/CD105+ HuAFCs underwent normal cycles of cell proliferation and self-renewal in the ovarian tissues of POF mice over the long-term. Conclusions: The mesenchymal stem cell properties and long-term <i>in vivo</i> survival of CD44+/CD105+ HuAFCs make them ideal seed cells for stem cell transplantation to treat POF.</p> ]]></description>

<title>Fluoroscopic Caudal Epidural Injections in Managing Post Lumbar Surgery Syndrome: Two-Year Results of a Randomized, Double-Blind, Active-Con&#173;trol Trial</title> 
<description><![CDATA[ <p><b><i>Study Design: </i></b>A randomized, active control, double-blind trial. <i>Objective</i>: To evaluate the effectiveness of fluoroscopically directed caudal epidural injections with or without steroids in managing chronic low back and lower extremity pain secondary to post lumbar surgery syndrome. <i>Summary of Background Data</i>: There is a paucity of evidence concerning caudal epidural injections for managing chronic persistent low back pain with or without lower extremity pain caused by post lumbar surgery syndrome.</p><p><b><i>Methods: </i></b>This active control randomized study included 140 patients with 70 patients in each group. Group I received 0.5% lidocaine, 10 mL; Group II received 9 mL of 0.5% lidocaine mixed with 1 mL of 6 mg of nonparticulate betamethasone. The multiple outcome measures included the numeric rating scale, the Oswestry Disability Index 2.0, employment status, and opioid intake with assessments at 3, 6, 12, 18, and 24 months posttreatment. Primary outcome was defined as at least 50% improvement in pain and Oswestry Disability Index scores. Patients with a positive response to the first 2 procedures with at least 3 weeks of relief were considered to be successful. All others were considered as failures.</p><p><b><i>Results: </i></b>Overall in Group I, 53% and 47% of the patients and in Group II, 59% and 58% of the patients, showed significant improvement with reduction in pain scores and disability index at 12 months and 24 months. In contrast, in the successful groups, significant pain relief and improvement in function were observed in 70% and 62% of Group I at one and 2 years; in 75% and 69% of Group II at one and 2 years. The results in the successful group showed that at the end of the first year patients experienced approximately 38 weeks of relief and at the end of 2 years Group I had 62 weeks and Group II had 68 weeks of relief. Overall total relief for 2 years was 48 weeks in Group I and 54 weeks in Group II. The average procedures in the successful groups were at 4 in one year and 6 at the end of 2 years.</p><p><b><i>Conclusion: </i></b>Caudal epidural injections of local anesthetic with or without steroid might be effective in patients with chronic persistent low back and/or lower extremity pain in patients with post lumbar surgery syndrome.</p> ]]></description>

<title>Impaired Secretion of Total Glucagon-like Peptide-1 in People with Impaired Fasting Glucose Combined Impaired Glucose Tolerance</title> 
<description><![CDATA[ <p>Objective: We assessed the serum glucagon-like peptide-1 (GLP-1) levels for Chinese adults with pre-diabetes (PD) and newly-diagnosed diabetes mellitus (NDDM) during oral glucose tolerance test (OGTT). The relationships between total GLP-1 level and islet &#946; cell function, insulin resistance (IR) and insulin sensitivity (IS) were also investigated.</p><p>Methods: A 75g glucose OGTT was given to 531 subjects. Based on the results, they were divided into groups of normal glucose tolerance (NGT), isolated impaired fasting glucose (IFG), isolated impaired glucose tolerance (IGT), IFG combined IGT (IFG+IGT) and NDDM. Total GLP-1 levels were measured at 0- and 2-hour during OGTT. Homeostasis model assessment of &#946; cell function (HOMA-&#946;), HOMA of insulin resistance (HOMA-IR), Gutt and Matsuda indexes were calculated. The relationships between GLP-1 level and &#946; cell function, IR and IS were analyzed.</p><p>Results: The levels of total fasting GLP-1 (FGLP-1), 2h GLP-1 (2hGLP-1) and 2hGLP-1 increments (&#8710;GLP-1) following OGTT reduced significantly in IFG+IGT and NDDM groups (P&#60;0.005). HOMA-&#946; , HOMA-IR, Gutt and Matsuda indexes demonstrated various patterns among NGT, isolated IFG, isolated IGT, IFG+IGT and NDDM groups (P&#60;0.05). Spearman rank correlation analysis and multivariable linear regression model suggested that some levels of correlation between GLP-1 levels, &#8710;GLP-1 and &#946; cell function, IR (P&#60;0.05).</p><p>Conclusions: The total GLP-1 levels and its response to glucose load decreased significantly in IFG+IGT group, compared to isolated IFG or IGT group. They were even similar to that of NDDM group. Moreover, there were observable correlations between impaired GLP-1 secretion and &#946; cell function, IR and IS.</p> ]]></description>

<title>Preoperative Management of Surgical Patients by &#8220;Shortened Fasting Time&#8221;: A Study on the Amount of Total Body Water by Multi-Frequency Impedance Method</title> 
<description><![CDATA[ <p><b>Aim:</b> Preoperative fasting is an established procedure to be practiced for patients before surgery, but optimal preoperative fasting time still remains controversial. The aim of this study was to investigate the effect of &#8220;shortened preoperative fasting time&#8221; on the change in the amount of total body water (TBW) in elective surgical patients. TBW was measured by multi-frequency impedance method.</p><p><b>Methods:</b> The patients, who were scheduled to undergo surgery for stomach cancer, were divided into two groups of 15 patients each. Before surgery, patients in the control group were managed with conventional preoperative fasting time, while patients in the &#8220;enhanced recovery after surgery (ERAS)&#8221; group were managed with &#8220;shortened preoperative fasting time&#8221; and &#8220;reduced laxative medication.&#8221; TBW was measured on the day before surgery and the day of surgery before entering the operating room. Defecation times and anesthesia-related vomiting and aspiration were monitored.</p><p><b>Results:</b> TBW values on the day of surgery showed changes in both groups as compared with those on the day before surgery, but the rate of change was smaller in the ERAS group than in the control group (2.4&#177;6.8% [12 patients] vs. &#8722;10.6&#177;4.6% [14 patients], p&#60;0.001). Defecation times were less in the ERAS group. Vomiting and aspiration were not observed in either group.</p><p><b>Conclusion:</b> The results suggest that preoperative management with &#8220;shorted preoperative fasting time&#8221; and &#8220;reduced administration of laxatives&#8221; is effective in the maintenance of TBW in elective surgical patients.</p> ]]></description>

<title>Cytotoxicity of 15-Deoxy-&#916;12,14-prostaglandin J2 through PPAR&#947;-independent Pathway and the Involvement of the JNK and Akt Pathway in Renal Cell Carcinoma</title> 
<description><![CDATA[ <p><b>Introduction:</b> Agonists of peroxisome proliferator-activated receptor gamma (PPAR&#947;) have been examined as chemopreventive and chemotherapeutic agents. The aim was to investigate the cytotoxicity and action mechanisms of 15-deoxy-&#916;<sup>12,14</sup>-prostaglandin J<sub>2</sub> (15d-PGJ<sub>2</sub>), one of endogenous ligands for PPAR&#947;, in terms of PPAR&#947;-dependency and the mitogen-activated protein kinase (MAPK) and Akt pathway in three human renal cell carcinoma (RCC)-derived cell lines.</p><p><b>Methods:</b> 786-O, Caki-2 and ACHN cells were used as human RCC-derived cell lines. Cell viability and caspase-3 activity was detected by fluorescent reagents, and chromatin-condensation was observed with a brightfield fluorescent microscope after staining cells with Hoechst33342. The expression levels of proteins were detected by Western blot analysis.</p><p><b>Results: </b>15d-PGJ<sub>2</sub> showed cytotoxicity in dose-dependent manner. 15d-PGJ<sub>2</sub> induced chromatin-condensation and elevated caspase-3 activity, and the cell viability was restored by co-treatment with a pan-caspase inhibitor, Z-VAD-FMK, indicating the involvement of caspase-dependent apoptosis. The cytotoxicity was not impaired by a PPAR&#947; inhibitor, GW9662, suggesting that 15d-PGJ<sub>2</sub> exerted the cytotoxicity in a PPAR&#947;-independent manner. Some antioxidants rescued cells from cell death induced by 15d-PGJ<sub>2</sub>, but some did not, suggesting that reactive oxygen species (ROS) did not contribute to the apoptosis. 15d-PGJ<sub>2</sub> also increased the expression levels of phospho-c-Jun N terminal kinase (JNK) in Caki-2 cells, and decreased those of phospho-Akt in 786-O cells, indicating that the JNK MAPK and the Akt pathways participated in the anticancer effects of 15d-PGJ<sub>2</sub> in some cell lines.</p><p><b>Conclusion:</b> 15d-PGJ<sub>2</sub> exerted cytotoxic effects accompanying caspase-dependent apoptosis, and this effect was elicited in a PPAR&#947;-independent manner in three cell lines. In addition, the JNK MAPK and Akt pathway was involved in the cytotoxicity of 15d-PGJ<sub>2</sub> to some extent in some cell line. Therefore, our study showed the 15d-PGJ<sub>2</sub> to potentially be an interesting approach for RCC treatment.</p> ]]></description>

<title>Role of Mitochondrial Translocation of Telomerase in Hepatocellular Carcinoma Cells with Multidrug Resistance</title> 
<description><![CDATA[ <p>Multidrug resistance (MDR) is a major obstacle of cancer chemotherapy. This study aimed to investigate the role of mitochondrial translocation of telomerase (hTERT) in MDR of human hepatocellular carcinoma (HCC) cells. In this study, three HCC cell lines (SK-Hep1/CDDP1 cells, SK-Hep1/CDDP2 cells and SK-Hep1/CDDP3 cells) with differential resistance index (RI) to cisplatin (CDDP) were induced by pulse treatment of SK-Hep1 (human hepatocellular cell line) with CDDP in vitro. The RI of SK-Hep1/CDDP1 cells, SK-Hep1/CDDP2 cells and SK-Hep1/CDDP3 cells was 5.14, 8.66, and 14.25, respectively, and all the cell lines showed cross-resistance to Doxorubicin (DOX) and 5-Fuorouracil (5-FU). The apoptosis rates in drug-resistant cells were significantly reduced. Cell cycle analysis revealed the ratio of drug-resistant cells in G2/M and S phases increased, while that in G1 phase decreased. Immunofluorescence staining and Western blot assay demonstrated, with the gradual elevation in RI, increasing hTERT translocated from the nuclei to the mitochondria, while real-time PCR indicated the shortening of telomere length in drug-resistant cells under the chemotherapeutic stress and the reduction of damaged mtDNA with the increase in RI. Furthermore, JC-1 staining also indicated the reduction of mitochondrial membrane potential in drug-resistant cells. The mitochondrial translocation of hTERT increases in multidrug-resistant cells and exerts protective effect on mitochondrial function. Drug-resistant tumor cells escape from apoptosis through hTERT-mediated mitochondrial protection. Mitochondrial translocation of hTERT may serve as an underlying mechanism of MDR.</p> ]]></description>

<title>Gender Difference in Prevalence of Signs and Symptoms of Temporomandibular Joint Disorders: A Retrospective Study on 243 Consecutive Patients</title> 
<description><![CDATA[ <p><b>Background</b>: This study evaluated the prevalence of the signs and symptoms of temporomandibular joint disorder (TMD) among patients with TMD symptoms. <b>Methods</b>: Between September 2011 and December 2011, 243 consecutive patients (171 females, 72 males, mean age 41 years) who were referred to the Department of Prosthodontics, Faculty of Dentistry, Karadeniz Technical University, Trabzon were examined physically and completed a questionnaire regarding age, gender, social status, general health, antidepressant drug usage, dental status, limited mouth opening, temporomandibular joint (TMJ) sounds, and parafunctions (bruxism, clenching). The data were analyzed using the chi-square test and binary logistic regression model (alpha = 0.05). <b>Results</b>: With a frequency of 92%, pain in the temporal muscle was the most common symptom, followed by pain during mouth opening (89%) in both genders. TMJ pain at rest, pain in the masseter muscle, clicking, grinding, and anti-depressant use were significantly more frequent in females than males. Age (<i>p</i>=0.006; odds ratio 0.954; 95% CI 0.922-0.987) and missing teeth (<i>p</i>=0.003; odds ratio 3.753; 95% CI 1.589-8.863) had significant effects on the prevalence of TMD. <b>Conclusion</b>: Females had TMD signs and symptoms more frequently than males in the study population. The most common problem in both genders was pain.</p> ]]></description>

<title>A Review of the Human Clinical Studies Involving Citrus aurantium (Bitter Orange) Extract and its Primary Protoalkaloid p-Synephrine</title> 
<description><![CDATA[ <p>This review summarizes the published as well as unpublished human studies involving <i>Citrus aurantium</i> (bitter orange) extract and its primary protoalkaloid <i>p</i>-synephrine, providing information and an assessment of the safety and efficacy of these widely used products. The results of over 20 studies involving a total of approximately 360 subjects that consumed <i>p</i>-synephrine alone or in combination with other ingredients are reviewed and critiqued. Over 50 % of the subjects involved in these studies were overweight/obese, and approximately two-thirds of these overweight/obese subjects consumed caffeine (132-528 mg/day) in conjunction with <i>p</i>-synephrine (10-53 mg/day). Bitter orange/<i>p</i>-synephrine containing products were consumed for up to 12 weeks. Approximately 44 % of the subjects consumed a bitter orange/<i>p</i>-synephrine only product, while the remainder consumed a complex product that contained multiple ingredients in addition to<i> p</i>-synephrine. In general, bitter orange extract alone <i>(p</i>-synephrine) or in combination with other herbal ingredients did not produce significant adverse events as an increase in heart rate or blood pressure, or alter electrocardiographic data, serum chemistry, blood cell counts or urinalysis. <i>p-</i>Synephrine alone as well as in combination products were shown to increase resting metabolic rate and energy expenditure, and modest increases in weight loss were observed with bitter orange extract/<i>p</i>-synephrine-containing products when given for six to 12 weeks. Longer term studies are needed to further assess the efficacy of these products and affirm their safety under these conditions.</p> ]]></description>

<title>The Integration and Functional Evaluation of Rabbit Pacing Cells Transplanted into the Left Ventricular Free Wall</title> 
<description><![CDATA[ <p>To evaluate the feasibility of cell transplantation to treat bradyarrhythmia, we analyzed the <i>in vivo</i> integration and pacing function after transplantation of mHCN4-modified rabbit bone marrow mesenchymal stem cells (MSCs) into the rabbit left ventricle free wall epicardium. In our investigation, we injected MSCs transduced with or without mHCN4 into the rabbit left ventricle free wall epicardium. Chemical ablation of the sinoatrial node was performed and bilateral vagus nerves were sequentially stimulated to observe premature left ventricular contraction or left ventricular rhythm. We found that the mHCN4-transduced MSC group had a significantly higher ventricular rate and a shorter QRS duration than that of the control and EGFP group. Furthermore, the mHCN4-transduced MSCs, but not the control cells, gradually adapted long-spindle morphology and became indistinguishable from adjacent ventricle myocytes. The modified MSCs showed pacing function approximately 1 week after transplantation and persisted at least 4 weeks after transplantation. In conclusion, a bradyarrhythmia model can be successfully established by chemical ablation of the sinoatrial node and sequential bilateral vagus nerve stimulation. The mHCN4-modified rabbit MSCs displayed evident dynamic morphology changes after being transplanted into rabbit left ventricle free wall epicardium. Our studies may provide a promising strategy of using modified stem cell transplantation to treat bradyarrhythmia.</p> ]]></description>

<title>Mannose Binding Lectin and Macrophage Migration Inhibitory Factor Gene Polymorphisms in Turkish Children with Cardiomyopathy: No Association with MBL2 Codon 54 A/B Genotype, but an Association between MIF -173 CC Genotype</title> 
<description><![CDATA[ <p>Myocardial inflammation is one of the commonest mechanisms in cardiomyopathy (CMP). Mannose binding lectin (MBL) is a key molecule in innate immunity, while macrophage migration inhibitory factor (MIF) is a constitutive element of the host defenses. We investigated the possible association between polymorphisms of MBL2 and MIF genes and CMP in Turkish children. Twenty-children with CMP and 30 healthy controls were analyzed for codon 54 A/B polymorphism in MBL, and -173 G/C polymorphism in MIF genes by using PCR-RFLP methods. No significant difference was found between genotypes and alleles of MBL2 gene codon 54 A/B polymorphism in patients and controls (p&#62;0.05). However, serum uric acid levels was found higher in dilated CMP patients with AA genotype. Frequency of MIF -173 CC genotype was significantly higher in patients (p&#60;0.05), and sodium levels were higher in patients with MIF -173 CC genotype. This study is the first to investigate the MBL and MIF gene polymorphisms in Turkish children with CMP. We conclude that CC genotype of MIF (-173) polymorphism may be a risk factor for CMP patients. However, further studies with larger samples are needed to address the exact role of this polymorphism in CMP.</p> ]]></description>

<title>Interaction between Polymorphisms of DNA Repair Genes Significantly Modulated Bladder Cancer Risk</title> 
<description><![CDATA[ <p>DNA repair is a primary defense mechanism against damage caused by exogenous and endogenous sources. We examined the associations between bladder cancer and 7 polymorphisms from 5 genes involved in the maintenance of genetic stability (MMR: MLH1-93G&#62;A; BER: XRCC1--77T&#62;C and Arg399Gln; NER:XPC Lys939Gln and PAT +/-; DSBR:ATM G5557A and XRCC7 G6721T) in 302 incident bladder cancer cases and 311 hospital controls. Genotyping was done using a polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) technique. The homozygous variant of XRCC7 G6721T (Odds Ratio [OR]: 2.36; 95% Confidence Interval [CI]: 1.13-4.92) was associated with increased bladder cancer risk. In an analysis of combined genotypes, the combination of XRCC1Arg399Gln (Gln allele) with XRCC1-77 T/T led to an increase in risk (OR: 1.61; 95% CI: 1.10-2.36). Moreover, when the XPCLys939Gln (Gln allele) (nucleotide excision repair [NER]) was present together with XRCC7 (T allele) (double strand break repair [DSBR]), the bladder cancer risk dramatically increased (OR: 4.42; 95% CI: 1.23-15.87). Our results suggest that there are multigenic variations in the DNA repair pathway involved in bladder cancer susceptibility, despite the existence of ethnic group differences.</p> ]]></description>

<title>Prevention of Propofol Injection Pain in Children: A Comparison of Pretreatment with Tramadol and Propofol-Lidocaine Mixture</title> 
<description><![CDATA[ <p><b>Background: </b>The pain on propofol injection is considered to be a common and difficult to eliminate problem in children. In this study, we aimed to compare the efficacy of pretreatment with tramadol 1 mg.kg<sup>-1</sup>and propofol-lidocaine 20 mg mixture for prevention of propofol induced pain in children.</p><p><b>Methods: </b>One hundred and twenty ASA I-II patients undergoing orthopedic and otolaryngological surgery were included in this study and were divided into three groups with random table numbers. Group C (n=39) received normal saline placebo and Group T (n=40) received 1 mg.kg<sup>-1</sup> tramadol 60 sec before propofol (180 mg 1% propofol with 2 ml normal saline) whereas Group L (n=40) received normal saline placebo before propofol-lidocaine mixture (180 mg 1% propofol with 2 ml %1 lidocaine). One patient in Group C was dropped out from the study because of difficulty in inserting an iv cannula. Thus, one hundred and nineteen patients were analyzed for the study. After given the calculated dose of propofol, a blinded observer assessed the pain with a four-point behavioral scale.</p><p><b>Results: </b>There were no significant differences in patient characteristics and intraoperative variables (p&#62;0.05) except intraoperative fentanyl consumption and analgesic requirement one hr after surgery among the groups (p&#60;0.05). Both tramadol 1 mg.kg<sup>-1</sup> and lidocaine 20 mg mixture significantly reduced propofol pain when compared with control group. Moderate and severe pain were found higher in control group (p&#60;0.05). The incidence of overall pain was 79.4% in the control group, 35% in tramadol group, 25% in lidocaine group respectively (p&#60;0.001).</p><p><b>Conclusions:</b> Pretreatment with tramadol 60 sec before propofol injection and propofol-lidocaine mixture were significantly reduced propofol injection pain when compared to placebo in children.</p> ]]></description>

<title>Validation of the Prediction Model for Success of Vaginal Birth after Cesarean Delivery in Japanese Women</title> 
<description><![CDATA[ <p><i>Aim:</i> To validate a previously developed prediction model for vaginal birth after cesarean (VBAC) using a Japanese cohort.</p><p><i>Methods:</i> We performed a cohort study of all term pregnant women with a vertex position, singleton gestation, and one prior low transverse cesarean delivery attempting a trial of labor between April 1985 and March 2010. Variables necessary for the prediction of successful VBAC were maternal age, pre-pregnancy body mass index, ethnicity, prior vaginal delivery, prior VBAC, and indication for prior cesarean delivery. They were extracted from medical records and put into the formula that calculates an individual woman's predicted VBAC success rate. The predicted rates were then partitioned into deciles and compared with the actual VBAC rates. The predictive ability of the model was assessed with a receiver operating characteristic and the area under the curve (AUC) was determined.</p><p><i>Results:</i> Seven hundred and twenty-five women who met the inclusion criteria had complete data available, of which 664 (91.6%) had VBAC. The predicted probability of VBAC, as calculated by the regression equation, was significantly higher in those who had a successful trial of labor (median 80.1%, interquartile range 71.5-88.7) than those who did not (median 69.4%, interquartile range 59.9-78.9, <i>P</i>&#60;0.001). The predictive model had AUC of 0.80, which was comparative to the originally described one. When the predicted rates were each deciles of over 70%, the actual success rates were more than 90%.</p><p><i>Conclusion:</i> The previously published prediction model for VBAC developed in the USA is also available to Japanese women.</p> ]]></description>

<title>Clinical Application of Pharmacogenetic-Based Warfarin-Dosing Algorithm in Patients of Han Nationality after Rheumatic Valve Replacement: A Randomized and Controlled Trial</title> 
<description><![CDATA[ <p><b>Background </b>The polymorphisms of VKORC1 and CYP2C9 play increasingly important roles in the inter-individual variability in warfarin dose. This study aimed to evaluate the feasibility of clinical application of pharmacogenetic-based warfarin-dosing algorithm in patients of Han nationality with rheumatic heart disease after valve replacement in a randomized and controlled trial. <b>Methods</b> One hundred and one consecutive patients of Han nationality with rheumatic heart disease undergoing valve surgery were enrolled and randomly assigned to an experimental group (n=50, based on CYP2C9 and VKORC1 genotypes, pharmacogenetic-based &#8220;predicted warfarin dose&#8221; for 3 days and then was adjusted to INR until stable warfarin maintenance dose) or a control group (n=51, 2.5mg/d for 3 days and then was adjusted to INR until stable warfarin maintenance dose). All included patients were followed for 50 days after initiation of warfarin therapy. The primary end-point was the time to reach a stable warfarin maintenance dose. <b>Results </b>During the follow-up, 84.0% patients in the experimental group and 58.8% patients in the control group received warfarin maintenance dose. Compared with control group, patients in the experimental group had shorter mean time elapse from initiation of warfarin therapy until warfarin maintenance dose (27.5&#177;1.8 d versus 34.7&#177;1.8 d, p&#60;0.001). Cox regression revealed that group (HR for experimental versus control group: 1.568, 95%CI 1.103-3.284) and age were two significant variables related to the time elapse from initiation of warfarin therapy until warfarin maintenance dose. The predicted warfarin maintenance dose was prominently correlated with the actual warfarin maintenance dose (r=0.684, p&#60;0.001). <b>Conclusion</b>: Based on CYP2C9 and VKORC1 genotypes, the pharmacogenetic-based warfarin-dosing algorithm may shorten the time elapse from initiation of warfarin therapy until warfarin maintenance dose. It is feasible for the clinical application of the pharmacogenetic-based warfarin-dosing algorithm in patients of Han nationality with rheumatic heart disease after valve replacement.</p> ]]></description>

<title>Zn2+-SCMC Versus HA for Preventing Intraperitoneal Adhesions: A Rat Model Study</title> 
<description><![CDATA[ <p><b>Background:</b> Intraperitoneal adhesion is a serious surgical postoperative complication. Using a rat model, we compared the effectiveness of intraperitoneally administered zinc-modified sodium carboxymethyl cellulose (Zn<sup>2+</sup>-SCMC) and hyaluronic acid (HA) in preventing postoperative intraperitoneal adhesions.</p><p><b>Materials and Methods:</b> Peritoneal adhesions were induced in 120 Wistar rats by scraping the cecal mucosa. The rats were randomized into a no treatment group (n = 40) or into a treatment group in which 3 ml of HA (n = 40) or Zn<sup>2+</sup>-SCMC (n = 40) was administered intraperitoneally before the abdominal wall was closed. Following sacrifice two weeks later, the intraperitoneal adhesions were scored and tissues were examined histologically using HE staining.</p><p><b>Results</b>: Eight animals died, five in the untreated group (mortality rate, 12.5%), two in the HA group (mortality rate, 5.0%) and one in the Zn<sup>2+</sup>-SCMC group (mortality rate, 2.5%). Relative to the untreated group, the incidence of intraperitoneal adhesions was 77.5% in the HA and 48.7% in the Zn<sup>2+</sup>-SCMC group, with the incidence significantly lower in the Zn<sup>2+</sup>-SCMC group (P &#60; 0.001). Both agents prevented intraperitoneal adhesions by promoting the repair of the abdominal serosa.</p><p><b>Conclusions:</b> Administration of Zn<sup>2+</sup>-SCMC was more effective in preventing intraperitoneal adhesions than HA.</p> ]]></description>

<title>Rap System of Stress Stimulation Can Promote Bone Union after Lower Tibial Bone Fracture: A Clinical Research</title> 
<description><![CDATA[ <p><b>Background </b>Lower tibial bone fracture may easily cause bone delayed union or nonunion because of lacking of dynamic mechanical load.</p><p><b>Objective </b>Research Group would design a new instrument as Rap System of Stress Stimulation (RSSS) to provide dynamic mechanical load which would promote lower tibial bone union postoperatively.</p><p><b>Methods </b>This clinical research was conducted from January 2008 to December 2010, 92 patients(male 61/female 31, age 16-70years, mean 36.3years) who suffered lower tibial bone closed fracture were given intramedullary nail fixation and randomly averagely separated into experimental group and control group(according to the successively order when patients went for the admission procedure). Then researchers analysed the clinical healing time, full weight bearing time, VAS (Visual Analogue Scales) score and callus growth score of Lane-Sandhu in 3,6,12 months postoperatively. The delayed union and nonunion rates were compared at 6 and 12 months separately.</p><p><b>Results </b>All the 92 patients had been followed up (mean 14 months). Clinical bone healing time in experimental group was 88.78&#177;8.80 days but control group was 107.91&#177;9.03days. Full weight bearing time in experimental group was 94.07&#177;9.81 days but control group was 113.24&#177;13.37 days respectively (P&#60;0.05). The delayed union rate in 6 months was 4.3% in experimental group but 10.9% in control group(P&#60;0.05). The nonunion rate in 12 months was 6.5% in experimental group but 19.6% in control group(P&#60;0.05). In 3, 6, 12 months postoperatively, VAS score and Lane-Sandhu score in experimental group had more significantly difference than them in control group.</p><p><b>Conclusions </b>RSSS can intermittently provide dynamic mechanical load and stimulate callus formation, promote lower tibial bone union, reduce bone delayed union or nonunion rate. It is an adjuvant therapy for promoting bone union after lower tibial bone fracture.</p> ]]></description>

<title>Symptomatic Venous Thromboembolism Is a Disease Related to Infection and Immune Dysfunction</title> 
<description><![CDATA[ <p>The characteristics of human genomics and cellular immune function between clinically symptomatic venous thromboembolism (VTE) and controls were systematically compared to explore the immunologic pathogenesis of VTE. Microarray assay showed the mRNA expressions of genes related to non-specific cellarer immune and cytokines were significantly down-regulated. Abnormal expressions of CD3+, CD4+, CD8+, NK marker CD16+56+, CD19 and aberrant CD4+/CD8+ ratio were detected in 54 among 56 patients. In PE patients, microarray assay revealed the imbalance in the expressions of genes related to the immune system. The expressions of genes related to non-specific immune cells and cytokines were markedly up-regulated and those associated with cellular immune were dramatically down-regulated. In VTE patients, cytological examination indicated the functions of NK cells were significantly compromised, and the antigen recognition and killing function of T cells markedly decreased. The consistence between genomic and cytological examination suggests the symptomatic VTE is closely associated with the infection and immune dysfunction.</p> ]]></description>

<title>Notch Signaling Pathway and Human Placenta</title> 
<description><![CDATA[ <p>Notch signaling was evolutionarily conserved and critical for cell-fate determination, differentiation and many other biological processes. Growing evidences suggested that Notch signaling pathway played an important role in the mammalian placental development. All of the mammalian Notch family proteins had been identified in human placenta except Delta-like 3, which appeared to affect the axial skeletal system. However the molecular mechanisms that regulated the Notch signaling pathway remained largely unknown in human placenta. Therefore, additional research was needed to investigate expression pattern of Notch family members and the mechanisms for activation of Notch signaling pathway in human placenta, which might help elucidate the roles of Notch signaling pathway in human placentation. This review would focus on the roles of Notch receptors and ligands in the human placental trophoblasts function and placental angiogenesis. It might hopefully provide perspectives for future research about human placentation of pregnancy complicated by preeclampsia and other placenta associated diseases.</p> ]]></description>

<title>Aspirin- and Clopidogrel-associated Bleeding Complications: Data Mining of the Public Version of the FDA Adverse Event Reporting System, AERS</title> 
<description><![CDATA[ <p><b>Objective:</b> Adverse event reports (AERs) submitted to the US Food and Drug Administration (FDA) were reviewed to assess the bleeding complications induced by the administration of antiplatelets and to attempt to determine the rank-order of the association.</p><p><b>Methods:</b> After a deletion of duplicated submissions and the revision of arbitrary drug names, AERs involving warfarin, aspirin, cilostazol, clopidogrel, ethyl icosapentate, limaprost alfadex, sarpogrelate, and ticlopidine were analyzed. Authorized pharmacovigilance tools were used for the quantitative detection of signals, i.e., drug-associated adverse events, including the proportional reporting ratio, the reporting odds ratio, the information component given by a Bayesian confidence propagation neural network, and the empirical Bayes geometric mean.</p><p><b>Results:</b> Based on 22,017,956 co-occurrences, i.e., drug-adverse event pairs, found in 1,644,220 AERs from 2004 to 2009, 736 adverse events were listed as warfarin-associated adverse events, and 147 of the 736 were bleeding complications, including haemorrhage and haematoma. Both aspirin and clopidogrel were associated with haemorrhage, but the association was more noteworthy for clopidogrel. As for bleeding complications related to the gastrointestinal system, e.g., melaena and haematochezia, the statistical metrics suggested a stronger association for aspirin than clopidogrel. The total number of co-occurrences was not large enough to compare the association with bleeding complications for the other 5 antiplatelets.</p><p><b>Conclusions:</b> The data strongly suggest the necessity of well-organized clinical studies with respect to antiplatelet-associated bleeding complications.</p> ]]></description>

<title>Sofnolime with Different Water Content Causes Different Effects in Two Sevoflurane Inhalational Induction Techniques with Respect to the Output of Compound-A</title> 
<description><![CDATA[ <p><b>Objective: </b>During sevoflurane anesthesia with Sofnolime for CO2 absorption, the factors affecting the production of compound A (a chemical is nepherotoxic) are still not clear. This study is designed to investigate the effects of different fresh gas flow during induction, the vital capacity induction (VCI) vs. the tidal volume breath induction (TBI) on the compound-A production with a fresh Sofnolime or a dehydrated Sofnolime using a simulated lung model.</p><p><b>Method: </b>The experiments were randomly divided into four groups: group one, VCIf, vital capacity fresh gas inflow with fresh Sofnolime; group two, TBIf, tidal volume breath fresh gas inflow with fresh Sofnolime; group three, VCId, vital capacity fresh gas inflow with dehydrated Sofnolime, and group four, TBId, tidal volume breath fresh gas inflow with dehydrated Sofnolime. The inspired sevoflurane was maintained at 8%, the concentrations of compound-A were assayed using Gas-spectrum technique, and Sofnolime temperatures were monitored at 1-min intervals throughout the experiment.</p><p><b>Results: </b>The mean and maximum concentrations of compound A were significantly higher in the vital capacity group than the tidal volume breath group (P&#60;0.01). At the beginning of anesthesia maintenance, the compound-A concentration in group VCIf was 36.28&#177;6.13 ppm, which was significantly higher than the 27.32&#177;4.21 ppm observed in group TBIf (P&#60;0.01). However, these values decreased to approximately 2 ppm in the dehydrated Sofnolime groups. Sofnolime temperatures increased rapidly in the dehydrated Sofnolime groups but slowly in the fresh Sofnolime groups.</p><p><b>Conclusion: </b>With fresh Sofnolime, vital capacity induction increased compound-A production in the circuit system compared with tidal volume breath induction. However, with dehydrated Sofnolime, the effects of the two inhalation induction techniques on compound-A output were not significantly different.</p> ]]></description>

<title>Management of Chronic Pain of Cervical Disc Herniation and Radiculitis with Fluoroscopic Cervical Interlaminar Epidural Injections</title> 
<description><![CDATA[ <p><b>Study Design: </b>A randomized, double-blind, active controlled trial.</p><p><b>Objective: </b>To evaluate the effectiveness of cervical interlaminar epidural injections of local anesthetic with or without steroids in the management of chronic neck pain and upper extremity pain in patients with disc herniation and radiculitis.</p><p><b>Summary of Background Data: </b>Epidural injections in managing chronic neck and upper extremity pain are commonly employed interventions. However, their long-term effectiveness, indications, and medical necessity, of their use and their role in various pathologies responsible for persistent neck and upper extremity pain continue to be debated, even though, neck and upper extremity pain secondary to disc herniation and radiculitis, is described as the common indication. There is also paucity of high quality literature.</p><p><b>Methods: </b>One-hundred twenty patients were randomly assigned to one of 2 groups: Group I patients received cervical interlaminar epidural injections of local anesthetic (lidocaine 0.5%, 5 mL); Group II patients received 0.5% lidocaine, 4 mL, mixed with 1 mL of nonparticulate betamethasone.</p><p>Primary outcome measure was &#8805; 50 improvement in pain and function. Outcome assessments included Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), opioid intake, employment, and changes in weight.</p><p><b>Results: </b>Significant pain relief and functional status improvement (&#8805; 50%) was demonstrated in 72% of patients who received local anesthetic only and 68% who received local anesthetic and steroids. In the successful group of participants, significant improvement was illustrated in 77% in local anesthetic group and 82% in local anesthetic with steroid group.</p><p><b>Conclusions: </b>Cervical interlaminar epidural injections with or without steroids may provide significant improvement in pain and function for patients with cervical disc herniation and radiculitis.</p> ]]></description>

<title>MicroRNA 21 Inhibits Left Ventricular Remodeling in the Early Phase of Rat Model with Ischemia-reperfusion Injury by Suppressing Cell Apoptosis</title> 
<description><![CDATA[ <p><b>Objective:</b> To determine the role of microRNA 21(miR-21) on left ventricular remodeling of rat heart with ischemia-reperfusion (I/R) injury and to investigate the underlying mechanism of miR-21 mediated myocardium protection.</p><p><b>Methods: </b>Rats were randomly divided into three groups: an I/R model group with Ad-GFP (Ad-GFP group), an I/R model group with Ad-miR-21 (Ad-miR-21 group) and a sham-surgery group. Changes in hemodynamic parameters were recorded at 1 week after I/R. Histological diagnosis was achieved by hematoxylin and eosin (H&#38;E). Left ventricular (LV) dimensions, myocardial infarct size, LV/BW, collagen type &#8544;, type &#8546; and PCNA positive cells were measured. Primary cultures of neonatal rat cardiac ventricular myocytes were performed and cell ischemic injury was induced by hypoxia in a serum- and glucose-free medium, and reoxygenation (H/R).MiR-21 inhibitor and pre-miR-21 were respectively added to the culture medium for the miR-21 knockdown and for the miR-21 up-regulation. qRT-PCR was used to determine the miR-21 levels in cultured cells. Flow cytometry was performed to examine the cell apoptosis.</p><p><b>Results</b>: In the Ad-miR-21 group, LV dimensions, myocardial infarct size, LV/BW, collagen type &#8544;, type &#8546; and PCNA positive cells all significantly decreased compared with the Ad-GFP group. At 1 week after I/R, the Ad-miR-21 significantly improved LVSP, LV +d<i>p</i>/d<i>t</i><sub>max</sub>, LV &#8722; d<i>p</i>/d<i>t</i><sub>min</sub>, and decreased heart rate (HR) and LVEDP compared with the Ad-GFP group. Compared with the Ad-GFP, the cell apoptotic rate significantly decreased in the Ad-miR-21 group. The miR-21 inhibitor exacerbated cardiac myocyte apoptosis and the pre-miR-21 decreased hypoxia/reoxygenation- induced cardiac myocyte apoptosis.</p><p><b>Conclusions</b>: Ad-miR-21 improves LV remodeling and decreases the apoptosis of myocardial cells, suggesting the possible mechanism by which Ad-miR-21 functions in protecting against I/R injury.</p> ]]></description>

<title>Frequency of Pulmonary Hypertension in Patients with COPD due to Biomass Smoke and Tobacco Smoke</title> 
<description><![CDATA[ <p><b>Objectives</b>; Pulmonary hypertension (PH) is a common and well established complication of chronic obstructive pulmonary disease (COPD). Its presence is associated with decreased survival. This study was designed to investigate the PH frequency and its relations in hospitalized tobacco and biomass related COPD patients. <b>Methods and Results</b>; The study was a retrospective review of inpatients with COPD defined as a history of tobacco or biomass smoking, Pulmonary function tests (PFT) within stable status, an echocardiogram within stable status. PH was defined as systolic pulmonary artery pressure (sPAP) &#62;35 mmHg. Of the 694 individuals, 600 had suitable aspects for inclusion of study. All Females were biomass exposer and males were tobacco smoker. The Prevalence of PH was found more frequent in females than males. It was more prominent in moderate level COPD cases (56,2% and 37,5%, P&#60;0,002). Both groups had airflow limitation, hypercapnia and hypoxemia, but no differences were found in terms of PaCO<sub>2</sub> and PaO2. However, FEV1 % was lower in males than females (p&#60;0,005). On the other hand, FVC % was lower in the females compared with the males (p &#60; 0.02). When analyzing the influence of PFT and demographic parameters on PH in separate COPD level groups, the results a bit varied among the groups. <b>Conclusion</b>; Our study demonstrated that PH frequency is higher in female COPD cases due to biomass smoke than in male COPD cases due to tobacco smoke. The influence of FVC % on the risk of a person having PH increased with increasing COPD level.</p> ]]></description>

<title>Effects of Antiretroviral Therapy on Autonomic Function in Early HIV Infection: A Preliminary Report</title> 
<description><![CDATA[ <p>Background: A prospective study was conducted in human immunodeficiency virus (HIV)-infected patients as they undergo alterations in their antiretroviral therapy (ART) to determine the effect of ART on autonomic function.</p><p>Methods: HIV-infected subjects who were either 1) na&#239;ve to ART and initiating ART, or 2) receiving ART and in HIV virologic failure for at least 4 months and were about to switch ART were enrolled in this study. Autonomic function assessment (cardiovagal, adrenergic, and sudomotor tests) was performed prior to and 4 months after initiating the new ART. Changes in clinical autonomic symptoms and virologic assessment were assessed.</p><p>Results: Twelve subjects completed the study: 92% male; median age (Q1, Q3) was 41.0 (28.0, 48.2) years; and 50% White/Non-Hispanic. Seventy-five percent were ART na&#239;ve while 25% were failing their ART regimen. The median CD4 count was 336.5 (245.3, 372.3) cells/mm<sup>3</sup>. All subjects achieved an undetectable HIV viral load by the 4-month follow-up visit. The majority of na&#239;ve subjects were started on an ART regimen of tenofovir / emtricitabine / efavirenz. There were no significant differences in autonomic function assessment, as measured by cardiovagal, adrenergic, and sudomotor tests, with regards to ART initiation.</p><p>Conclusion: This is the first study to examine the effects of initiating ART on autonomic function in early HIV infection. This study found no appreciable differences of ART on the autonomic nervous system when ART is initiated early in the course of HIV disease. ART may not contribute to short-term changes in autonomic function.</p> ]]></description>

<title>Post-reperfusion Syndrome during Renal Transplantation: A Retrospective Study</title> 
<description><![CDATA[ <p>Post-reperfusion syndrome (PRS) is a serious, widely reported complication following the reperfusion of an ischemic tissue or organ. We sought to determine the prevalence, risk factors and short-term outcomes of PRS related renal transplantation. We conducted a retrospective, case-control study of patients undergoing renal transplantation between July 2006 and March 2008. Identification of PRS was based on a drop in mean arterial pressure by at least 15% within 5 minutes of donor kidney reperfusion. Of the 150 consecutive renal transplantations reviewed, 6 patients (4%) met criteria for post-reperfusion syndrome. Univariate analysis showed that an age over 60, diabetes mellitus, Asian race, and extended criteria donors increased the odds of developing PRS by 4.8 times (95% CI [1.2, 20]; <i>P</i>=.0338), 4.5 times (95% CI [1.11, 18.8]; <i>P</i>=.0378), 35.5 times (95% CI [3.94, 319.8]; P=0.0078) and 9.6 times (95% CI [1.19, 76.28] <i>P</i>=0.0115) respectively. Short term follow-up revealed increased graft failure rate within 6 months (6% vs. 16% <i>P</i>=0.0125) and almost twice the number of hospital days post-transplant in PRS cohorts (5.43 &#177; 2.29 vs. 10.8 &#177; 7.29 <i>P</i>=&#60;0.0001). Despite limited reporting, PRS appears to be a relatively common complication of renal transplantation and is associated with increase morbidity.</p> ]]></description>

<title>A Large Amniocele with Protruded Umbilical Cord Diagnosed by 3D Ultrasound</title> 
<description><![CDATA[ <p>An amniocele is a herniation of the amniotic sac through a uterine defect. Uterine rupture during pregnancy may develop as a result of a pre-existing injury, uterine anomaly, or unscarred uterus. A 30-year-old patient, with a history of 2 vaginal deliveries, presented an amniocele complicated by left fundal perforation and was evaluated with 3-dimensional ultrasound at 23 weeks. Because of worsening lower abdominal pain and vaginal bleeding, she underwent exploratory laparotomy. Herein, we report a uterine rupture with amniocele.</p> ]]></description>

<title>Analysis on the Pathogenesis of Symptomatic Pulmonary Embolism with Human Genomics</title> 
<description><![CDATA[ <p><b>BACKGROUND</b>: In the present study, the whole human genome oligo microarray was employed to investigate the gene expression profile in symptomatic pulmonary embolism (PE).</p><p><b>METHODS</b>: Twenty patients with PE and 20 age and gender matched patients without PE as controls were enrolled into the present study in the same period. The diagnosis of PE was based on the clinical manifestations and findings on imaging examinations. Acute arterial and/or venous thrombosis was excluded in controls. The whole human genome oligo microarray was employed for detection. Statistical analysis was performed with t test following analysis of very small samples of repeated measurements and Gene Ontology (GO) analysis.</p><p><b>RESULTS</b>: Genomic data showed no damage to vascular endothelial cells in PE patients. Genomic data only found increased mRNA expression of a small amount of coagulation factors in PE patients. In the PE group, anticoagulant proteins, Fibrinolytic system and proteins related to platelet functions only played partial roles in the pathogenesis of PE. In addition, the mRNA expressions of a fraction of adhesion molecules were markedly up-regulated. Gene Ontology analysis showed the genes with down-regulated expressions mainly explain the compromised T cell immunity. Symptomatic VTE patients have compromised T cell immunity.</p><p><b>CONCLUSION: </b>The damage to vascular endothelial cells is not necessary in the pathogenesis of VTE, and only a fraction of factors involved in the shared coagulation cascade are activated. Genomic results may provide a new clue for clinical diagnosis, treatment and prevention of VTE.</p> ]]></description>

<title>18&#945;-Glycyrrhetinic Acid Down-Regulates Expression of Type I and III Collagen via TGF-&#914;1/Smad Signaling Pathway in Human and Rat Hepatic Stellate Cells</title> 
<description><![CDATA[ <p><b>Objective:</b> To investigate the effects of 18&#945;-glycyrrhetinic acid (18&#945;-GA) on the expression of type I and III collagen in human and rat hepatic stellate cells (HSC) and to explore the role of TGF-&#946;1/Smad signaling pathway involved.</p><p><b>Methods:</b> Following 18&#945;-GA treatment, the cell viability and cell growth were detected to determine the optimal concentration of 18&#945;-GA. The expressions of TGF-&#946;1/Smad signaling-related genes including type I and III collagen in human and rat HSCs before and after 18&#945;-GA treatment were measured by real time PCR. The expression of related proteins was verified by western blot assay. The phosphorylation level of Smad2 and Smad3 was detected by immunocytochemistry. The DNA binding activities of SP-1, AP-1 and NF-&#954;B were measured by both EMSA and ArrayStar transcription factor activity assay.</p><p><b>Results: </b>18&#945;-GA could decrease the mRNA and protein expression of Smad3, type I and III collagen, increase the Smad7 expression in human and rat HSCs (P&#60;0.05), and reduce phosphorylation level of Smad3 at 24 h and 48 h after treatment. The DNA binding activities of transcription factors were suppressed by 18&#945;-GA in human and rat HSCs at 24 h, and the activities reduced in a time dependent manner with the lowest activities at 48 h, especially for SP-1.</p><p><b>Conclusion:</b> 18&#945;-GA could inhibit the mRNA and protein expression of type I and III collagen in human and rat HSCs, which may be attributed to down-regulation of Smad3, up-regulation of Smad7, and inhibition of DNA binding activities of SP-1, AP-1 and NF-&#954;B.</p> ]]></description>

<title>Analysis of the Mineral Composition of the Human Calcified Cartilage Zone</title> 
<description><![CDATA[ <p>As the connecting tissue between the hyaline articular cartilage and the subchondral bone, calcified cartilage zone (CCZ) plays a great role in the force transmission and materials diffusion. However, the questions that remain to be resolved are its mineral composition and organization. In this study, 40 healthy human knee specimens were harvested; first the CCZ was dissected and observed by Safranin O/fast green staining, then CCZ chemical characteristics were measured by using amino acid assay and X-ray diffraction. The percentage of dry weight of type II collagen as an organic compound of CCZ was 20.16% &#177; 0.96%, lower than that of the hyaline cartilage layer (61.39% &#177; 0.38%); the percentage of dry weight of hydroxyapatite as an inorganic compound was 65.09% &#177; 2.31%, less than that of subchondral bone (85.78% &#177; 3.42%). Our study provides the accurate data for the reconstruction of the CCZ in vitro and the elucidation of CCZ structure and function.</p> ]]></description>

<title>BioShuttle Mobility in Living Cells Studied with High-Resolution FCS &#38; CLSM Methodologies</title> 
<description><![CDATA[ <p>With the increase in molecular diagnostics and patient-specific therapeutic approaches, the delivery and targeting of imaging molecules and pharmacologically active agents gain increasing importance. The ideal delivery system does not exist yet. The realization of two features is indispensable: first, a locally high concentration of target-specific diagnostic and therapeutic molecules; second, the broad development of effective and safe carrier systems. Here we characterize the transport properties of the peptide-based BioShuttle transporter using FFM and CLSM methods. The modular design of BioShuttle-based formulations results in a multi-faceted field of applications, also as a theranostic tool.</p> ]]></description>

<title>Expression of Glioma-associated Oncogene Homolog 1 is Associated with Invasion and Postoperative Liver Metastasis in Colon Cancer</title> 
<description><![CDATA[ <p><b>Objective: </b>To investigate the expression of glioma-associated oncogene homolog 1(Gli-1) in colon cancer and its association with clinicopathological parameters and postoperative liver metastasis.</p><p><b>Methods: </b>Expression of Gli-1 was detected by immunohistochemistry in paraffin-embedded specimens of 96 cases of colon cancer. Relationship between Gli-1 expression and clinicopathological parameters, postoperative liver metastasis were analyzed.</p><p><b>Results:</b> Gli-1 protein expression was significantly increased in colon cancer tissues compared to normal colon tissues (P = 0.037). Gli-1 expression in colon tissues was increased in patients with lymph node metastases (P = 0.022) and higher T stages (P = 0.030). Postoperative live metastasis-free survival period was significantly longer in low Gli-1 expression group than that of high Gli-1 expression group (48.22&#177;10.03 months vs 20.46&#177;6.32 months, P=0.001). Multivariate analysis showed that Gli-1 expression level is an independent prognostic factor for postoperative live metastasis-free survival.</p><p><b>Conclusion:</b> Colon cancer is associated with an upregulation of Gli-1 protein expression in colon tissues. In patients with colon cancer, Gli-1 expression level is closely related to lymph node metastases, T stages and postoperative live metastasis-free survival periods, indicative of a possible role of Gli-1 expression in colon cancer progression.</p> ]]></description>

<title>A Comparison of Ketamine and Paracetamol for Preventing Remifentanil Induced Hyperalgesia in Patients Undergoing Total Abdominal Hysterectomy</title> 
<description><![CDATA[ <p><b>Background</b>: The aim of this prospective, randomized, placebo-controlled study was to compare the effects of ketamine and paracetamol on preventing remifentanil induced hyperalgesia.</p><p><b>Methods:</b> Ninety patients undergoing total abdominal hysterectomy were randomly assigned to one of three groups to receive (I) either saline infusion; (II) 0.5 mg/kg ketamine iv bolus or (III) 1000 mg iv paracetamol infusion before induction of anesthesia. Until the skin closure, anesthesia was maintained with 0.4 &#181;g/kg/min remifentanil infusion in all groups, additionally Group II received 5 &#181;g/kg/min ketamine infusion. Pressure pain thresholds were measured the day before surgery during the preoperative visit for baseline measurements and repeated postoperatively at 24 and 48 hours (hrs). Pressure pain thresholds were established by digital algometer on three different peri- incisional regions for calculating mean pressure pain threshold values. The visual analogue scale (VAS), sedation scores, total morphine consumption and side effects were assessed postoperatively.</p><p><b>Results:</b> Demographic characteristics, duration of surgery and anesthesia were similar in the three groups. Pain thresholds at the incision region were significantly lower at 24 and 48 hrs postoperatively in Group I than the other Groups (p&#60; 0.05). In Group &#1030;, pain thresholds were lower compared with preoperative baseline values. Thresholds in Group &#1030;&#1030; and Group &#1030;&#1030;&#1030; were higher compared with preoperative baseline values (p&#60; 0.05) The VAS scores at all evaluation times were significantly higher in Group &#1030; when compared to Group &#1030;&#1030; and at 2, 4, 6 ,12 hrs were higher in Group I than Group &#1030;&#1030;&#1030; (p&#60; 0.05). The morphine consumption was higher in Group &#1030;&#1030;&#1030; at 24 and 48 hrs postoperatively (p&#60; 0.05).</p><p><b>Conclusion:</b> It was shown that ketamine and paracetamol were both effective in preventing remifentanil induced hyperalgesia.</p> ]]></description>

<title>Omeprazole- and Esomeprazole-associated Hypomagnesaemia: Data Mining of the Public Version of the FDA Adverse Event Reporting System</title> 
<description><![CDATA[ <p><b>Objective:</b> Case reports showing that proton-pump inhibitors (PPIs), omeprazole and esomeprazole, can cause hypomagnesaemia have been accumulating since 2006. In this study, the reports submitted to the Adverse Event Reporting System (AERS) of the US Food and Drug Administration (FDA) were evaluated to assess omeprazole and esomeprazole in terms of susceptibility to hypomagnesaemia.</p><p><b>Methods:</b> After a revision of arbitrary drug names and the deletion of duplicated submissions, the reports involving omeprazole and esomeprazole were analyzed. Standardized official pharmacovigilance tools were used for the quantitative detection of a signal, i.e., an association between a drug and an adverse drug event, including the proportional reporting ratio, the reporting odds ratio, the information component given by a Bayesian confidence propagation neural network, and the empirical Bayes geometric mean.</p><p><b>Results:</b> A total of 22,017,956 co-occurrences were found in 1,644,220 reports from 2004 to 2009, where a co-occurrence was a pair of a drug and an adverse drug event. In total, 818 and 743 adverse drug events were listed as omeprazole- and esomeprazole-associated, with hypomagnesaemia ranking 85<sup>th</sup> and 135<sup>th</sup>, respectively. Although both PPIs were associated with hypomagnesaemia, the statistical metrics suggested that the association was more noteworthy for omeprazole.</p><p><b>Conclusion:</b> The data obtained in this study do not provide sufficient evidence to recommend systematic monitoring of magnesium levels in plasma, but chronic exposure to a PPI can lead to severe hypomagnesaemia.</p> ]]></description>

<title>Facial Soft Tissue Changes after Maxillary Impaction and Mandibular Advancement in High Angle Class II Cases</title> 
<description><![CDATA[ <p>The aim of this study was to determine the vertical and anteroposterior alterations in the soft, the dental and the skeletal tissues associated with the facial profile after Le Fort I maxillary impaction in conjunction with sagittal split osteotomy for mandibular advancement performed in patients with a high angle Class II skeletal deformity.</p><p>The study population consists of 21 patients (11 females and 10 males, mean age 24.5&#177;1.6 years) who underwent Le Fort I maxillary impaction in conjunction with sagittal split osteotomy for mandibular advancement. Lateral cephalograms were obtained prior to the surgery and 1.3&#177;0.2 years postoperatively. Wilcoxon test was performed to compare the pre- and postsurgical cephalometric measurements. Pearson correlation test was carried out to determine the relative changes in skeletal, dental and the facial soft tissues.</p><p>The insignificant decrease in the nasolabial angle was correlated with the significant decrease in the vertical position of the nose due to the nasal protraction noticed after bimaxillary surgery. The retraction of both the upper lip and the upper incisors was correlated with the insignificant decrease in the columella-lobular angle. The insignificant decrease in both the vertical height of the mandibular B point and the lower incisors was correlated with the insignificant decrease in vertical height of the soft tissue pogonion, attributable to the resulting superior movement of the soft tissues of the chin and the counter clockwise rotation of the mandible after maxillary impaction and bilateral sagittal split osteotomy, respectively.</p><p>Le Fort I maxillary impaction in conjunction with mandibular sagittal split osteotomy for mandibular advancement significantly affected the vertical and anteroposterior positions of the maxilla and the mandible, respectively. When performed in combination, these surgical techniques may efficiently alter the position of upper incisor and the nasal position in both vertical and anteroposterior directions. Bimaxillary orthognathic surgery seems to be an efficient method for obtaining satisfactory results in the appearance of the soft, the dental and the skeletal tissues associated with the facial profile in patients with high angle Class II skeletal deformity.</p> ]]></description>

<title>Remifentanil Prevents Tourniquet-Induced Arterial Pressure Increase in Elderly Orthopedic Patients under Sevoflurane/N2O General Anesthesia</title> 
<description><![CDATA[ <p>Aims: Prolonged tourniquet inflation produces a hyperdynamic cardiovascular response. We investigated the effect of continuous remifentanil infusion on systemic arterial pressure, heart rate, and cardiac output changes during prolonged tourniquet use in elderly patients under sevoflurane/N<sub>2</sub>O general anesthesia.</p><p>Methods: Thirty female patients scheduled for knee replacement arthroplasty were infused with either remifentanil at a target organ concentration of 2.0 ng/mL (remifentanil group, n = 15) or saline (control group, n = 15) after induction of anesthesia. Anesthesia was maintained with sevoflurane and N<sub>2</sub>O. Heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), cardiac index (CI), total systemic vascular resistance index (TSVRI), BIS, end-tidal sevoflurane concentration (EtSEVO), and end-tidal carbon dioxide concentration (EtCO<sub>2</sub>) were measured during the study period.</p><p>Results: There were significant differences in mean HR, SAP, DAP, and EtSEVO over time between the groups (P = 0.047, P &#60; 0.001, P = 0.017, and P &#60; 0.001, respectively). There was a statistically significant time trend effect (P &#60; 0.001) in HR, SAP, DAP, and CI between the groups, with a statistically significant time-group interaction between the two groups (P = 0.02, 0.007, 0.001, 0.01, respectively).</p><p>Conclusion: The present study demonstrated that infusion with remifentanil prevented an increase in hemodynamic pressure during tourniquet inflation in elderly patients under sevoflurane/N<sub>2</sub>O general anesthesia.</p> ]]></description>

<title>Risk Factors for Ventilator Dependency Following Coronary Artery Bypass Grafting</title> 
<description><![CDATA[ <p><b>Background: </b>Ventilator dependency following coronary artery bypass grafting (CABG) is often associated with significant morbidity and mortality. However, few reports have focused on the independent risk factors for ventilator dependency following CABG. This study aimed to evaluate the independent risk factors for ventilator dependency following coronary artery bypass grafting (CABG). <b>Methods:</b> The relevant pre-, intra- and post-operative data of patients without a history of chronic obstructive pulmonary disease undergoing isolated CABG from January 2003 to December 2008 in our center were retrospectively analyzed. Elapsed time between CABG and extubation of more than 48 hours was defined as postoperative ventilator dependency (PVD). <b>Results:</b> The incidence of PVD was 13.8% (81/588). The in-hospital mortality in the PVD group was significantly higher than that in the non-PVD group (8.6% versus 2.4%, p=0.0092). Besides the length of ICU and hospital stay, PVD correlated with negative respiratory outcomes. The independent risk factors for PVD were preoperative congestive heart failure (OR=2.456, 95%CI 1.426-6.879), preoperative hypoalbuminemia (OR=1.353, 95%CI 1.125-3.232), preoperative arterial oxygen partial pressure (PO<sub>2</sub>) (OR=0.462, 95%CI 0.235-0.783) and postoperative anaemia (OR=1.541, 95%CI 1.231-3.783). <b>Conclusions: </b>Preoperative congestive heart failure, preoperative hypoalbuminemia, low preoperative PO<sub>2</sub> and postoperative anaemia were identified as four independent risk factors for ventilator dependency following CABG.</p> ]]></description>

<title>Surgical Treatment for Unstable Distal Clavicle Fracture with Micromovable and Anatomical Acromioclavicular Plate</title> 
<description><![CDATA[ <p>Between 2006 and 2009, 18 patients of distal clavicle fracture were treated with micro-movable and anatomical acromioclavicular plate (MAAP) in our department. According to the Neer's classification, all cases were unstable with type IIA (12 cases) and type IIB (6 cases). Functional outcome was evaluated using the Karlsson's criteria. The mean follow-up was 18 months (range, 12-36months). No postoperative plate screws complication was observed. Osseous union could be achieved at a mean time of 12 weeks after operation in 18 patients (range, 8 -16 weeks). According to Karlsson's criteria, radiographic appearances and postoperative shoulder functional recovery revealed a good and excellent rate in these cases. We conclude that surgical treatment using MAAP seems to be a good option for unstable type II fractures of the distal clavicle. This technique allows for reliable fixation with early functional exercises and functional recovery.</p> ]]></description>

<title>Cardioprotective Effect of Sodium Ferulate in Diabetic Rats</title> 
<description><![CDATA[ <p>Reactive oxygen species (ROS) play important roles in the occurrence and development in diabetic cardiomyopathy (DC). Ferulic acid is one of the ubiquitous compounds in diet. Sodium ferulate (SF) is its sodium salt. SF has potent free radical scavenging activity and can effectively scavenge ROS. The study investigated the effect of SF on cardioprotection in diabetic rats. The diabetic rats induced by streptozotocin (STZ) were treated with SF (110mg/kg) by gavage per day for 12 weeks. Results showed that the levels of nitric oxide (NO) and superoxide dismutase (SOD) activity in plasma and myocardium in SF-treated group were significantly higher than those in diabetic control group. The levels of malondialdehyde (MDA) in plasma and myocardium in SF-treated group were significantly lower than those in diabetic control group. Expression of connective tissue growth factor (CTGF) in myocardium in SF-treated group was apparently lower than that in diabetic control group. Compared with normal control group, electron micrographs of myocardium in diabetic control group showed apparently abnormality, while that was significantly ameliorated in SF-treated group. The study demonstrated that SF has a cardioprotective effect via increasing SOD activity and NO levels in plasma and myocardium, inhibiting oxidative stress in plasma and myocardium, and inhibiting the expression of CTGF in myocardium in diabetes rats.</p> ]]></description>

<title>Clinical Factors Affecting the Direct Cost of Patients Hospitalized with Acute Exacerbation of Chronic Obstructive Pulmonary Disease</title> 
<description><![CDATA[ <p><b>Background</b>: Chronic obstructive pulmonary disease (COPD) is a disease of increasing significance in terms of economic and social burden due to its increasing prevalence and high costs. Direct costs of COPD are mostly associated with hospitalization expenditures. In this study, our objective was to investigate the costs of hospitalization and factors affecting these costs in patients hospitalized due to acute exacerbation of COPD (AECOPD).</p><p><b>Methods:</b> A total of 284 patients hospitalized AECOPD were included in the study. Data were examined retrospectively using the electronic hospital charts.</p><p><b>Results:</b> Mean duration of hospitalization was 11.38 &#177; 6.94 days among study patients. Rates of admission to the intensive care unit, initiation of non-invasive mechanical ventilation (NIMV) and invasive mechanical ventilation (MIV) were 37.3% (n=106), 44.4% (n=126) and 18.3% (n=52) respectively. The rate of mortality was 14.8% (n=42). Mean cost of a single patient hospitalized for an AECOPD was calculated as $1765 &#177; 2139. Mean cost of admission was $889 &#177; 533 in standard ward, and $2508 &#177; 2857 in intensive care unit (ICU). The duration of hospitalization, a FEV1% predicted value below 30%, having smoked 40 package-years or more, the number of co-morbidities, NIMV, IMV, ICU, exitus and the number of hospitalizations in the past year were among the factors that increased costs significantly. Hospital acquired pneumonia, chronic renal failure and anemia also increased the costs of COPD significantly.</p><p><b>Conclusion:</b> The costs of treatment increase with the severity of COPD or with progression to a higher stage. Efforts and expenditures aimed at preventing COPD exacerbations might decrease the costs in COPD.</p> ]]></description>

<title>Synergic Effect of Compression Therapy and Controlled Active Exercises Using a Facilitating Device in the Treatment of Arm Lymphedema</title> 
<description><![CDATA[ <p><b>Trial design</b>: A randomized controlled trial was performed to evaluate the effect of the combination of compression therapy with active exercising using a facilitating apparatus on arm lymphedema. <b>Method:</b> Twenty women with a mean age of 63.3 years were evaluated; all had lymphedema resulting from breast cancer treatment. The inclusion criterion was a difference of 200 mL in size between arms. The apparatus used, called 'pulley system', is a vertical iron wheel fixed on a support at a distance of 10 cm from the patient's body. Participants were submitted to two series of active exercises using this facilitating device, one series using a compression sleeve and the other without. Each series consisted of four 12-minute sessions of exercises separated by 3-minute rest intervals. Volumetry was performed before and after each series of exercises. The paired t-test was utilized for statistical analysis (p-value &#60; 0.05). <b>Results</b>: A significant mean reduction (p-value &#60; 0.007) and non-significant mean increase (p-value &#60; 0.2) in volumes were observed during exercising with and without compression, respectively. <b>Conclusion</b>: Controlled active exercising utilizing a facilitating apparatus while wearing a compression sleeve reduces the size of lymphedematous arms.</p> ]]></description>

<title>Cerebral Falx Mature Teratoma with Rare Imaging in an Adult</title> 
<description><![CDATA[ <p>Intracranial mature teratoma is a rare lesion in adults. Despite several intracranial mature teratomas had been reported not to be located at the midline region, no one was found to be within cerebral falx. Herein, we reported a 37-year-old female patient with an intracranial mature teratoma confined within frontal cerebral falx. Her main complaint was intermitted headache, which could not be relieved recently by taking painkiller. Excepting for mild papilledema, we did not find positive neurological signs on physical examination. CT scanning showed it was a round homogenously hypodense lesion with hyperdense signal at its rim. MRI revealed the lesion was 3.5cm&#215;3.6cm&#215;4.5cm in volume, with uniformed hypointensity on T1WI, hyperintensity on T2WI and enhancement in the capsule. It was totally removed via inter-hemispheric approach, and we found the lesion was confined within the frontal cerebral falx. Postoperatively, it was proved histologically to be a mature teratoma. At three years of fellow up, neither neurological deficits nor recurrent sings on MRI was found. To our best knowledge, this is the first case of intracranial mature teratoma within cerebral falx.</p> ]]></description>

<title>Keratocystic Odontogenic Tumors: Predictive Factors of Recurrence by Ki-67 and AgNOR Labelling</title> 
<description><![CDATA[ <p>Purpose: The purpose of the present study was to investigate the possible role of Ki-67 and argyrophilic nucleolar organizing regions (AgNOR) between the recurrent and nonrecurrent keratocystic odontogenic tumors (KCOTs). Another aim was to compare the correlation between these two markers.</p><p>Materials and Methods: 22 KCOTs were evaluated retrospectively. The actual proliferative activity of the KCOT was measured by Ki-67 labelling index and argyrophilic nucleolar organizing regions AgNOR count per nucleus. Results: Recurrence occurred in 3 patients (13.6%) during the follow-up period (mean follow-up, 37.8 months) The Ki-67 and AgNOR counts were significantly higher in the recurrent lesions comparing to the non-recurrent lesions. (p=0,045; p=0,049) The correlation between Ki-67 and AgNOR counts was found to be positive (r=0,853 p=0,0001).</p><p>Conclusion: Within the limit of the present study, it is thought that Ki-67 and AgNOR might be helpful as a prognostic marker for the recurrences of KCOTs. These markers reinforced the meaning of the new classification of the lesion as an odontogenic tumor. Enucleation with curettage or decompression following enucleation with curettage is a simple and appropriate surgical model for the treatment of KCOT despite the relative high recurrence rate. On the other hand, the conservative treatment can be chosen only if there is no coronoid invasion, no interruptive cortical lysis and no tissular invasion.</p> ]]></description>

<description><![CDATA[ <p><b>Objective:</b> In this study hypothesing the translocation of oral bacteria from oropharynx into the middle ear cavity may be involved in the pathogenesis of otitis media with effusion (OME), we aimed to investigate the presence and similarity of <i>Fusobacterium nucleatum</i> and <i>Treponema denticola</i> in saliva, nasopharyngeal secretion and the middle ear effusion samples from the children with OME.</p><p><b>Methods:</b> Totally 20 children with OME undergoing myringotomy and ventilation tube placement were attended. Stimulated saliva samples were collected after otorhinolaryngological and oral examinations were done. The middle ear effusion and nasopharyngeal secretions were collected during the operations. The presence of <i>F. nucleatum</i> and <i>T. denticola</i> were detected using 16SrRNA-based PCR. The clonal similarities of the bacteria were detected in the samples which the same bacteria had been detected in each samples of the same child. After DNA sequencing, clonal similarity was determined by 16SrRNA gene clone library analysis. The sequences from each clone were compared with similar sequences of reference organisms by FASTA search.</p><p><b>Results:</b><i> T. denticola</i> was detected only in four (20%) saliva and in one (5%) nasopharyngeal sample. <i>F. nucleatum</i> was detected in 11 (55%) saliva, eight (40%) nasopharyngeal and six (30%) middle ear effusion samples. Sequences from <i>F.nucleatum</i> clones derived from three different anatomic sites within patients were similar in 33% of OME patients, indicating their genetic relatedness.</p><p><b>Conclusions:</b> Bacteria involved in this process most likely originate from the oropharynx since they show a close genetic relatedness with their oropharyngeal counterparts.</p> ]]></description>

<title>Donepezil Combined with Natural Hirudin Improves the Clinical Symptoms of Patients with Mild-to-Moderate Alzheimer's Disease: A 20-Week Open-Label Pilot Study</title> 
<description><![CDATA[ <p><b><i>Aim:</i> </b>To evaluate the efficacy and safety of donepezil plus natural hirudin in patients with mild-to-moderate Alzheimer's Disease. <b><i>Methods:</i></b> In the 20-week, randomized, open-label and controlled study, 84 patients received either donepezil (5 mg/day for the first 4 weeks and 10 mg/day thereafter) or donepezil plus natural hirudin (3 g/day) treatment. Efficacy was reflected by the change of the total scores of Alzheimer's Disease Assessment Scale cognitive subscale (ADAS-Cog), Activities of Daily Life (ADL) and Neuropsychiatric Inventory (NPI). <b><i>Results:</i></b> The patients with the donepezil plus natural hirudin treatment showed more significant improvement in the daily activities and the decline of the cognition than those with donepezil treatment. Significant difference was present in the groups since the 8th week. No group difference was found in the NPI change. However, within the hirudin treatment group, more powerful efficacy including NPI assessment was found in the patients with vascular risk factors (VRF) as comparing to with those without VRF. The combination of donepezil and natural hirudin was well tolerated. The dropout rate was greater in the donepezil and natural hirudin (50%) treatment group than in the donepezil (39%) treatment group. Similar result was found in the incidence of adverse events (23.8% vs 19.0%), but there was no statistical difference between the two groups. Adverse events were the most common reason for the dropout. Although hemorrhage and hypersensitiveness were more common in donepezil plus Maixuekang treatment (11.9% and 7.1%) group than in donepezil treatment (2.4% and 2.4%) group, no significant difference was present between the two groups. Economic problem was another important reason for the patients' withdrawal. <b><i>Conclusions:</i></b> Compared with the donepezil treatment in the patients with mild-to-moderate AD, our results suggest that donepezil combined with natural hirudin may improve the treatment effects in the ADL, BPSD and cognition of the patients. Furthermore, this joint treatment is safe.</p> ]]></description>

<title>Laparoscopic Management of Perforated Meckel's Diverticulum in Adults</title> 
<description><![CDATA[ <p><b>Objective:</b> To determine the role of laparoscopy in diagnosis and surgical treatment of perforated Meckel's diverticulum (MD) in adults.</p><p><b>Methods:</b> Between July 2003 and July 2011, fifteen patients were seen with perforated MD. Eleven were male and four were female. The median age was 38 years (range, 21-68). All patients presented with a sudden onset of pain. Among them 9 had a past medical history of bloody stools and /or chronic recurrent abdominal pain. 2 were preoperatively diagnosed with perforated MD confirmly and 4 suspiciously, 9 with perforated acute appendicitis. All 15 patients underwent exploratory laparoscopy.</p><p><b>Results:</b> 4 patients with broad-base(&#8807; 2 cm) and 2 patients with narrow-base(&#60;2 cm) whose perforative site was near the base underwent laparoscopically assisted extracorporal bowel segment resection, the other 9 patients with narrow-base(&#60;2 cm) underwent laparoscopically intraabdominal wedge resection of the MD. No intraoperative or postoperative complications occurred. The median hospital stay was 4 days (range, 2-7days). The histopathologic studies showed heterotopic gastric mucosa (HGM) in 10 cases (66.7%). All patients recovered uneventfully.</p><p><b>Conclusion:</b> To patients with sudden abdomen pain mimic acute appendicitis accompanied by a past medical history of bloody stools and/or chronic recurrent abdominal pain, proferated MD should be kept in mind as a differential diagnosis. Laparoscopy is a safe and effective surgical modality for diagnosis of proferated MD and has a therapeutic role that results in an excellent cosmetic result.</p> ]]></description>

<title>COX-2 Expression and Tumor Angiogenesis in Thyroid Carcinoma Patients among Northeast Chinese Population-Result of a Single-Center Study</title> 
<description><![CDATA[ <p><b>Objective: </b>Cyclooxygenase-2 (COX-2), one of the rate-limiting enzymes in the metabolism of arachidonic acid which is reported to be involved in the pathogenesis of many human tumors. As well, Vascular endothelial growth factor (VEGF) is well known to be involved in the infiltration and metastasis of many kinds of cancers. The aim of this study was to further elucidate the clinicopathologic significance of the immunohistochemical expressions of COX-2 and VEGF in thyroid carcinoma.</p><p><b>Methods:</b> Eighty-five patients with thyroid neoplasms were enrolled in our study from December 2003 to January 2010 from the authors' institution retrospectively. Their tumors were examined in the Department of Pathology, the First Bethune Hospital of Jilin University. Immunohistochemistry was performed on paraffin-embedded tissues sections using monoclonal anti-human COX-2 and VEGF antibodies. The tissues were classified into four types: papillary, follicular, medullary and undifferentiated. The patients ranged in age from 23 to 71 years. Breast cancer slides acted as control slides. The immunohistochemical stains were quantified by staining intensity and by the proportion of positively stained cells which were stained brown or yellow.</p><p><b>Results:</b> The results were analysed by &#967;<sup>2</sup> test. COX-2 and VEGF expressions were stronger in thyroid carcinoma than in thyroid adenomas and normal tissues (<i>P</i>&#60;0.01). COX-2 and VEGF expressions in thyroid carcinoma correlated with the tumor type and TNM stage.</p><p><b>Conclusion:</b> Our results suggest that expression of COX-2 and VEGF may promote angiogenesis of thyroid carcinoma, its infiltration, and metastasis.</p> ]]></description>

<title>Hem-o-lok Clip Found in Common Bile Duct after Laparoscopic Cholecystectomy and Common Bile Duct Exploration: A Clinical Analysis Of 8 Cases</title> 
<description><![CDATA[ <p>Currently laparoscopic cholecystectomy (LC) and common bile duct exploration (LCBDE) has become the standard surgical procedure for cholecystolithiasis and choledocholithiasis. During the operation cystic duct and vessels are usually controlled by Hem-o-lok clips. However, recently we found clips dropping into CBD in 8 patients during fiberoptic choledochoscope 2-3 months after operation. Therefore, there is risk that clip can migrate during postoperative period, which probably lead to hemorrhage and bile leakage after LC if this occurs within postoperative few days, or even cause recurrent stone in CBD. So, using of Hem-o-lok clips may be not a safe method to control vessels and cystic duct during LC. To our knowledge, this condition has not previously been reported. In our view, other more effective and safe method ligating cystic duct and gallbladder vessels, such as effective and convenient thread knotting method, should be investigated.</p> ]]></description>

<title>Effects of STAT3 Gene Silencing and Rapamycin on Apoptosis in Hepatocarcinoma Cells</title> 
<description><![CDATA[ <p>The PI3K/Akt/mTOR and JAK/STAT3 signaling pathways are important for regulating apoptosis, and are frequently activated in cancers. In this study, we targeted STAT3 and mTOR in human hepatocellular carcinoma Bel-7402 cells and examined the subsequent alterations in cellular apoptosis. The expression of STAT3 was silenced with small interfering RNA (siRNA)-expressing plasmid. The activity of mTOR was inhibited using rapamycin. Following treatment, Annexin V/propidium iodide staining followed by flow cytometry and Hoechst33258 immunofluorescence staining was used to examine cellular apoptosis. JC-1 staining was used to monitor depolarization of mitochondrial membrane (&#916;&#936;m). Furthermore, the expression of activated caspase 3 protein was analyzed by Western blotting. Compared to non-treated or control siRNA-transfected cells, significantly higher levels of apoptosis were detected in siSTAT3-transfected or rapamycin-treated cells (<i>P</i> &#60; 0.05), which was further enhanced in cells targeted for both molecules (<i>P</i> &#60; 0.05). The pro-apoptotic effects were accompanied with concomitant depolarization of mitochondrial membrane and up-regulation of activated caspase 3. Combined treatments using rapamycin and STAT3 gene silencing significantly increases apoptosis in Bel-7402 cells, displaying more dramatic effect than any single treatment. This study provides evidence for targeting multiple molecules in cancer therapy.</p> ]]></description>

<title>Strangulated Intestinal Obstruction Secondary to a Typical Obturator Hernia: A Case Report with Literature Review</title> 
<description><![CDATA[ <p>Obturator hernia is a rare pelvic hernia with incidence of 1%. It's a significant cause of intestinal obstruction in emaciated elderly women. Delayed diagnosis and surgical intervention contributed to its relatively high morbidity and mortality. We present a typical case of obturator hernia with positive Howship-Romberg sign and Hannington-Kiff sign. The diagnosis was confirmed by spiral CT preoperatively. During the emergency laparotomy, the incarcerated intestine was reduced and removed. Obturator foramen was repaired by simple suture. The patient recovered uneventfully and no recurrence occurred during the follow-up. The obturator hernia should be included in the differential diagnosis if clinically suspected. Early diagnosis and prompt surgical treatment are essential to reduce the morbidity and mortality associated with obturator hernia.</p> ]]></description>

<title>Congenital Bronchial Atresia: Diagnosis and Treatment</title> 
<description><![CDATA[ <p>This study aimed to retrospectively summarize the clinical signs, diagnosis, and treatment of congenital bronchial atresia (CBA) in 12 patients. Chest radiographs and computed tomographic (CT) images of 12 patients with CBA treated in the Chinese People's Liberation Army General Hospital were reviewed. Analysis of chest radiographs revealed ten patients had hilar mass-like shadows and two had pneumonia-like shadows; most patients (n = 8) showed hyperlucency of the peripheral lung fields. CT revealed a mucocele in all the patients (n = 12); the mucoceles were round in four patients and club-like in eight. In 80% of the cases (n = 10), associated anomalies, including occlusions of the bronchus central to the mucocele, emphysematous changes of the peripheral lung fields, bronchogenic cyst, and anomalous branching of the bronchial tree and vascular structure were observed. CBA was detected in the right lobe in eight patients and the left lobe in the remaining four. No surgical intervention was performed in 5 CBA patients and the remaining 7 patients underwent surgery, including lobectomy in 5 patients and local resection in 2 patients. Among these 7 patients, 3 had a preoperative diagnosis of malignant disease, and the remaining 4 had severe clinical symptoms that could not be effectively treated by medicines. All patients were followed up, and none experienced obvious discomfort. CBA is a relatively rare and benign malformation disease. Chest CT is the procedure of choice for diagnosis. The presence of a bronchocele and surrounding emphysematous changes are typical radiologic findings in CBA. Surgery should be reserved only for patients with serious complications secondary to the atretic bronchus.</p> ]]></description>

<title>Isolated Biliary Cryptococcosis Manifesting as Obstructive Jaundice in an Immunocompetent Adult</title> 
<description><![CDATA[ <p>Cryptococcosis is a symptomatic fungal infection caused by <i>Cryptococcus</i>, which frequently occurs in patients who are immunologically compromised or chronically ill. Localized involvement of the hepatobiliary system in an immunocompetent adult is extremely rare. We report a unique case of isolated biliary cryptococcosis manifesting as obstructive jaundice and mimicking hilar cholangiocarcinoma in an immunocompetent woman. By integrating surgical and antifungal drug therapy, the disease was effectively controlled. Despite an increasing incidence of biliary malignancies, hepatobiliary surgeons and gastroenterologists must maintain a high index of suspicion for other rare possibilities of non-specific biliary inflammation.</p> ]]></description>

<title>Cancer and Radiation Therapy: Current Advances and Future Directions</title> 
<description><![CDATA[ <p>In recent years remarkable progress has been made towards the understanding of proposed hallmarks of cancer development and treatment. However with its increasing incidence, the clinical management of cancer continues to be a challenge for the 21<sup>st</sup> century. Treatment modalities comprise of radiation therapy, surgery, chemotherapy, immunotherapy and hormonal therapy. Radiation therapy remains an important component of cancer treatment with approximately 50% of all cancer patients receiving radiation therapy during their course of illness; it contributes towards 40% of curative treatment for cancer. The main goal of radiation therapy is to deprive cancer cells of their multiplication (cell division) potential. Celebrating a century of advances since Marie Curie won her second Nobel Prize for her research into radium, 2011 has been designated the Year of Radiation therapy in the UK. Over the last 100 years, ongoing advances in the techniques of radiation treatment and progress made in understanding the biology of cancer cell responses to radiation will endeavor to increase the survival and reduce treatment side effects for cancer patients. In this review, principles, application and advances in radiation therapy with their biological end points are discussed.</p> ]]></description>

<title>Effect of Bone Morphogenetic Protein-2 on Proliferation and Apoptosis of Gastric Cancer Cells</title> 
<description><![CDATA[ <p><b>Objective: </b>To investigate the effects of bone morphogenetic protein-2 (BMP-2) on the proliferation, differentiation and apoptosis of normal human gastric mucosal cells and gastric cancer cells.</p><p><b>Methods:</b> Poorly differentiated gastric cancer BGC823 cells, moderately differentiated gastric cancer cells and normal human gastric mucosal epithelial GES-1 cells were independently treated with recombinant human BMP-2 or its inhibitor Noggin. MTT assay was performed to detect the proliferation, flow cytometry done to measure the cell cycle and apoptosis and immunohistochemistry carried out to determine the expression of cyclin-dependent kinase 4 (CDK4).</p><p><b>Results: </b>BMP-2 exerted inhibitory effect on the growth of all types of cells and the inhibition become more evident with the increase of BMP-2 dose. After treatment with 200 ng/ml BMP-2, cancer cells arrested in G1 phase and those in S phase reduced. Gastric cancer cells had higher CDK4 expression than GES-1 cells. BMP-2 decreased CDK-4 expression in cancer cells but had no influence in GES-1 cells. Noggin conferred promotive effect on the growth of 3 types of cells. In 2 types of cancer cells, treatment with 2000 ng/ml Noggin significantly increased the proportion of cells in S phase but reduced that in G1 phase. However, Noggin did not affect the cell cycle of GES-1 cells. The CDK4 expression was markedly increased in 2 types of cancer cells but that of GES-1 remained unchanged after treatment with 2000 ng/ml Noggin.</p><p><b>Conclusions: </b>BMP-2 may inhibit the proliferation of both normal and malignant gastric epithelial cells, down-regulate CDK4 expression in gastric cancer cells and arrest gastric cancer cells in G1-phase in cell cycle. Through antagonizing BMP-2, Noggin, may accelerate the proliferation of gastric cancer cells. Thus, the abnormality of BMP signaling pathway may play an important role in the pathogenesis of gastric cancer.</p> ]]></description>

<title>Effects of a Sliding Plate on Morphology of the Epiphyseal Plate in Goat Distal Femur</title> 
<description><![CDATA[ <p>The aim of this study was to observe the effects of a sliding plate on the morphology of the epiphyseal plate in goat distal femur. Eighteen premature female goats were divided randomly into sliding plate, regular plate and control groups. Radiographic analysis and histological staining were performed to evaluate the development of epiphyseal plate at 4 and 8 weeks after surgery. In the sliding plate group, the plate extended accordingly as the epiphyseal plate grows, and the epiphyseal morphology was kept essential normal. However, the phenomenon of the epiphyseal growth retardation and premature closure were very common in the regular plate group. In addition, the sliding plate group exhibited more normal histologic features and Safranin O staining compared to the regular plate group. Our results suggest that the sliding plate can provide reliable internal fixation of epiphyseal fracture without inhibiting epiphyseal growth.</p> ]]></description>

<title>Abdominal Multiple Splenosis Mimicking Liver and Colon Tumors: A Case Report and Review of the Literature</title> 
<description><![CDATA[ <p>Splenosis is not an uncommon disease. However, it is often misdiagnosed as malignant tumors, and then the patients underwent unnecessary operations. Unfortunately, it is very difficult to diagnose it prior to operation. We report a rare case of a 49-year-old female patient with liver and colon splenosis, misdiagnosed as liver and colon tumors, and summarize experience how to diagnose it preoperatively according to literatures. We come to conclusion that in patients who ever underwent splenectomy especially owning to trauma, and were found mass in abdomen, clinicians must consider the existence of splenosis, and take some measures, such as scintigraphy with (99m) Tc labelled heat-denatured erythrocyte rather than biopsy, to diagnose it correctly to prevent unnecessary operations.</p> ]]></description>

<title>Cancer Survivors in the United States: A Review of the Literature and a Call to Action</title> 
<description><![CDATA[ <p><b>Background: </b>The number of cancer survivors in the U.S. has increased from 3 million in 1971, when the National Cancer Act was enacted, to over 12 million today. Over 70% of children affected by cancer survive more than 10 years, and most are cured. Most cancer survivors are adults, with two-thirds of them 65 years of age or older and two-thirds alive at five years. The most common cancer diagnoses among survivors include breast, prostate and colorectal cancers. This review was conducted to better appreciate the challenges associated with cancer survivors and the opportunities healthcare providers have in making a difference for these patients.</p><p><b>Methods: </b>Comprehensive review of literature based on PubMed searches on topics related to cancer survivorship, and associated physical, cognitive, socio-economic, sexual/behavioral and legal issues.</p><p><b>Results: </b>At least 50% of cancer survivors suffer from late treatment-related side effects, often including physical, psychosocial, cognitive and sexual abnormalities, as well as concerns regarding recurrence and/or the development of new malignancies. Many are chronic in nature and some are severe and even life-threatening. Survivors also face issues involving lack of appropriate health maintenance counseling, increased unemployment rate and workplace discrimination.</p><p><b>Conclusions: </b>Advances in the diagnosis and treatment of cancer will lead to more survivors and better quality of life. However, tools to recognize potentially serious long-lasting side effects of cancer therapy earlier in order to treat and/or prevent them must be developed. It is incumbent upon our health care delivery systems to make meeting these patients' needs a priority.</p> ]]></description>

<description><![CDATA[ <p><i>In vitro</i>, nitric oxide (NO) has been shown to have antimicrobial activity against a wide range of viruses, including influenza A virus. Therefore, we hypothesized that inhaled nitric oxide (iNO) would increase survival <i>in vivo</i> by reducing the viral load in C57Bl/6 mice infected with a lethal dose of influenza A/WSN/33 (H1N1; WSN/33) virus. NO was delivered to influenza-infected mice either continuously or intermittently at 80 or 160 ppm, respectively, using both prophylactic and post-infection treatment strategies. Murine survival and weight loss were assessed, and lung viral load was quantified via plaque assay. Here, we report that iNO administered prophylactically or post-influenza infection failed to improve survival of infected mice. No difference in lung viral load was observed between experimental groups. Although NO has antiviral activity against influenza A virus <i>in vitro</i>, iNO therapy provided no apparent benefit when used for treatment of influenza A virus infection <i>in vivo</i>.</p> ]]></description>

<title>Rapid Detection of rpoB Mutations in Rifampin Resistant M. tuberculosis from Sputum Samples by Denaturing Gradient Gel Electrophoresis</title> 
<description><![CDATA[ <p><b>Objective</b>: To establish a rapid detection method for identifying <i>rpoB</i> mutations associated with rifampin (RIF) resistance in sputum specimens.</p><p><b>Methods</b>: We detected <i>rpoB</i> mutations directly in 90 sputum specimens collected from suspected tuberculosis patients using PCR-based denaturing gradient gel electrophoresis (DGGE) and compared these results with those obtained by <i>rpoB</i> sequencing and conventional drug susceptibility testing.</p><p><b>Results</b>: The positive detection rate of <i>Mycobacterium tuberculosis</i> (<i>M. tuberculosis</i>) was 52.2% by Acid-Fast Bacilli staining and 72.2% by conventional <i>mycobacterial</i> culture. In contrast, the positive rate was significantly higher (93.3%) by PCR-based detection of the <i>rpoB</i> gene in the same specimens. Furthermore, 75% of the tested specimens presented abnormal patterns compared with the wild-type pattern (standard H37Rv strain) analysed by DGGE. A total of 12 different patterns, representing 12 different <i>rpoB</i> mutations, were observed in the 63 abnormal patterns. The match rate of <i>rpoB</i> mutations detected by DGGE reached 96.9% when compared to DNA sequencing.</p><p><b>Conclusion</b>: Our findings indicate that PCR-based DGGE is a rapid and reliable bio-technique for direct detection of <i>rpoB</i> mutations associated with RIF resistance in the sputum of suspected tuberculosis patients.</p> ]]></description>

<title>What Questions do People Ask on a Human Papillomavirus Website? A Comparative Analysis of Public and Private Questions</title> 
<description><![CDATA[ <p>Objective: In 2004, we launched the question and answer (Q&#38;A) section on a human papillomavirus (HPV) website (<ext-link ext-link-type="uri" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.hpvkorea.org">www.hpvkorea.org</ext-link>) that provides ample and regularly updated information about HPV. The purpose of this study is to collect data pertaining to questions posed on this website about HPV and its related diseases and analyze the type of questions and frequency before and after introduction of HPV vaccine in Korea. Using these results, we intend to determine the clinical and practical implications for doctors treating HPV and for HPV website providers.</p><p>Method: Data were collected from March 2004 to July 2011. This study analyzed all the questions that were asked on the website during this period. The questions were categorized into 2 groups, according to whether they were asked publicly or privately. The 10 categories for classification were determined on the basis of the contents of the questions by 4 researchers with medical degrees (Ph.D.) related to HPV research. The frequency of the questions was separately determined for the public and private question formats. Also, we compared the type of questions and frequency before and after introduction of HPV vaccine in Korea and evaluated the changes in the 2 groups over the 2 periods studied.</p><p>Results: Of the 3,062 subjects who visited the HPV website, 2,330 subjects asked public questions and 732 asked private questions. The most frequent question was &#8220;I have been infected with HPV, and I want to know about the treatment options for HPV infection and cervical dysplasia&#8221; (n = 1156, 37.8%), and the second most common question was &#8220;What are the transmission routes of HPV?&#8221; (n = 684, 22.3%). The third most common question was &#8220;How long does it take for HPV infection to spontaneously remit?&#8221; (n = 481, 15.7%).</p><p>Of the 2,330 public questions, the most common question types pertained to the treatment of HPV and cervical dysplasia, HPV transmission, HPV remission, and risk of cervical cancer (in that order). Of the 732 private questions, the most frequent question types pertained to the HPV transmission, treatment of HPV and cervical dysplasia, genital warts, and HPV &#38; pregnancy (in that order). The type and frequency of public and private questions showed statistical differences between the 2 groups (p &#60; 0.001).</p><p>Conclusion: Our results show that when people consult an internet site about HPV, they actually want to seek about &#8220;treatment of HPV and cervical dysplasia&#8221;, &#8220;HPV transmission&#8221;, &#8220;HPV remission&#8221;, &#8220;genital warts&#8221;, and &#8220;risk of cervical cancer&#8221; (in this order). Also, our results showed that &#8220;genital warts&#8221; and &#8220;HPV &#38; pregnancy&#8221; may have been considered embarrassing topics. Thus, these findings can be used to make informed recommendations for future clinical or internet-based communications with patients and the general public.</p> ]]></description>

<title>Oral and Maxillofacial Considerations in Gardner's Syndrome</title> 
<description><![CDATA[ <p>Gardner's Syndrome is a variant of familial adenomatosis polyposis (FAP) with a triad consisting of polyps of the colon, multiple osteomas and surface tumors of soft and hard tissue. The intestinal polyps have a %100 risk of undergoing malignant transformation, therefore early identification of this disease is very important. There are several symptoms of Gardner's syndrome in the oral and maxillofacial surgery, which can be discovered during routine dental examination. We report a case of a 25-year old male patient with Gardner's syndrome who has not any intestinal polyps but osteomas in the mandible and jaw deformalities.</p> ]]></description>

<title>Effects of Two Fluoride Varnishes and One Fluoride/Chlorhexidine Varnish on Streptococcus mutans and Streptococcus sobrinus Biofilm Formation in Vitro</title> 
<description><![CDATA[ <p><b>Aims</b>: The aim of this study was to evaluate and to compare the effect of two fluoride varnishes and one fluoride/chlorhexidine varnish on <i>Streptococcus mutans</i> and <i>Streptococcus sobrinus</i> biofilm formation, in vitro.</p><p><b>Study design</b>: Standard acrylic discs were prepared and divided into groups based on the varnish applied to the disc surface: Fluor Protector, Bifluoride 12, and Fluor Protector + Cervitec (1:1). Untreated discs served as controls. In the study groups, biofilms of <i>S. mutans</i> and <i>S. sobrinus </i>were formed over 24 h, 48 h, and 5 days. The fluoride concentrations in the monospecies biofilms and viable counts of<i> S. mutans</i> and <i>S. sobrinus </i>were investigated.</p><p><b>Results</b>: In all study groups, a statistically significant increase in the viable number of <i>S. mutans</i> and <i>S. sobrinus</i> cells was observed between 24 h and 5 days. In both monospecies biofilms, the greatest antibacterial efficacy was detected in the Fluor Protector and Fluor Protector + Cervitec groups at 24 h. For all groups, the amount of fluoride released was highest during the first 24 h, followed by a significant decrease over the next 4 days. A negative correlation was detected between fluoride concentration and antibacterial effect in those groups with biofilms containing both species. Despite the release of high levels of fluoride, the greatest number of viable <i>S. mutans</i> and <i>S. sobrinus </i>cells was detected in the Bifluoride 12 group.</p><p><b>Statistics</b>: The data were analyzed using GraphPad Prism software (ver. 3).</p><p><b>Conclusions</b>: The Fluor Protector + Cervitec varnish exerted prolonged antibacterial effects on <i>S. mutans</i> and <i>S. sobrinus </i>biofilms compared to the other varnishes tested.</p> ]]></description>

<title>Potential Impact of the Financial Crisis on Outpatient Hospital Visits due to Otorhinolaryngologic Disorders in Crete, Greece</title> 
<description><![CDATA[ <p>The public health effect of financial crises has been emphasized in previous studies. In addition, a series of otorhinolaryngologic disorders and manifestations has been related to psychological factors in the literature. Such conditions include temporomandibular joint disorders, laryngopharyngeal reflux, chronic tinnitus, and vertigo. Focusing on the outpatient database records of a large hospital in Crete, Greece, the objective of this retrospective study was to explore possible occurrence variations within the prementioned otorhinolaryngologic morbidity which may be potentially attributed to increased levels of socioeconomic stress. Results revealed that although the total number of visits between two periods - before and after the beginning of the financial crisis in Greece - was comparable, a significant increase in the diagnosis of two disorders, namely vertigo and tinnitus was found. In addition, a trend toward increased rate of diagnosis for reflux and temporomandibular joint disorders was noted. Potential implications of these findings are discussed. In conclusion, health care providers in this as well as in other countries facing similar socio-economic conditions should be aware of potential changes in the epidemiologic figures regarding specific medical conditions.</p> ]]></description>

<title>Relationship between Antithyroid Antibody and Pregnancy Outcome following in Vitro Fertilization and Embryo Transfer</title> 
<description><![CDATA[ <p><b>Objective:</b> To investigate the impact of antithyroid antibody on pregnancy outcome following the in vitro fertilization and embryo transfer (IVF-ET).</p><p><b>Methods:</b> A total of 90 patients (156 cycles) positive for antithyroid antibody (ATA+ group) and 676 infertile women (1062 cycles) negative for antithyroid antibody (ATA- group) undergoing IVF/ICSI from August 2009 to August 2010 were retrospectively analyzed.</p><p><b>Results:</b> There was no significant difference in the days of ovarian stimulation, total gonadotropin dose, serum E2 level of HCG day and number of oocytes retrieved between the two groups. The fertilization rate, implantation rate and pregnancy rate following IVF-ET were significantly lower in women with antithyroid antibody than in control group (64.3% vs 74.6%, 17.8% vs 27.1% and 33.3% vs 46.7%, respectively), but the abortion rate was significantly higher in patients with antithyroid antibody (26.9% vs 11.8%).</p><p><b>Conclusion: </b>Patients with antithyroid antibody showed significantly lower fertilization rate, implantation rate and pregnancy rate and higher risk for abortion following IVF-ET when compared with those without antithyroid antibody. Thus, the presence of antithyroid antibody is detrimental for the pregnancy outcome following IVF-ET.</p> ]]></description>

<title>Relationship of Visual Cortex Function and Visual Acuity in Anisometropic Amblyopic Children</title> 
<description><![CDATA[ <p><b>Purpose: </b>To detect the functional deficit of the visual cortex in anisometropic amblyopia children using functional magnetic resonance imaging (fMRI) technique, and investigate the relationship between visual acuity and visual cortex function.</p><p><b>Methods</b>: Blood oxygenation level-dependent fMRI (BOLD-fMRI) was performed in ten monocular anisometropic amblyopia children and ten normal controls. fMRI images were acquired in two runs with visual stimulation delivered separately through the sound and amblyopic eyes. Measurements were performed in cortical activation of striate and extrastriate areas at the occipital lobe. The relationship between cortex function and visual acuity was analyzed by Pearson partial analysis.</p><p><b>Results: </b>The activation areas of both the striate and extrastriate cortices in the amblyopic eyes were significantly lower than that of the sound fellow eyes. No relationship was found between the striate and extrastriate cortex activation. No relationship was found between the visual cortical activation of striate, extrastriate areas and visual acuity of anisometropic amblyopes.</p><p><b>Conclusions</b>: BOLD-fMRI revealed the independent striate and extrastriate cortical deficits in anisometropic amblyopes. In addition, the visual acuity lesion and the striate and extrastriate cortical deficits were not parallel, and results of fMRI examination have much potential value in the evaluation of amblyopia.</p> ]]></description>

<title>P-wave Dispersion for Predicting Paroxysmal Atrial Fibrillation in Acute Ischemic Stroke</title> 
<description><![CDATA[ <p><b>Background:</b> Detection of paroxysmal atrial fibrillation (PAF) in acute ischemic stroke patients poses diagnostic challenge. The aim of this study was to predict the presence of PAF by means of 12-lead ECG in patients with acute ischemic stroke. Our hypothesis was that P-wave dispersion (P<sub>d</sub>) might be a useful marker in predicting PAF in patients with acute ischemic stroke.</p><p><b>Methods:</b> 12-lead resting ECGs, 24-hour Holter recordings and echocardiograms of 400 patients were analyzed retrospectively. PAF was detected in 40 patients on 24-hour Holter monitoring. Forty out of 360 age and gender matched patients without PAF were randomly chosen and assigned as the control group. Demographics, P-wave characteristics and echocardiographic findings of the patients with and without PAF were compared.</p><p><b>Results:</b> Maximum P-wave duration (p=0.002), P<sub>d</sub> (p&#60;0.001) and left atrium diameter (p=0.04) were significantly higher in patients with PAF when compared to patients without PAF. However, in binary logistic regression analysis P<sub>d</sub> was the only independent predictor of PAF. The cut-off value of P<sub>d</sub> for the detection of PAF was 57.5 milliseconds (msc). Area under the curve was 0.80 (p&#60;0.001). On a single 12-lead ECG, a value higher than 57.5 msc predicted the presence of PAF with a sensitivity of 80% and a specificity of 73%.</p><p><b>Conclusion:</b> P<sub>d</sub> on a single 12-lead ECG obtained within 24 hours of an acute ischemic stroke might help to predict PAF and reduce the risk of recurrent strokes.</p> ]]></description>

<title>High-risk Human Papillomavirus Infection in Low Risk Women: Incidence, Patient Characteristics, and Clinical Meaning for Cervical Cancer</title> 
<description><![CDATA[ <p><b>Objective</b>: To investigate the incidence of high-risk human papillomavirus (HPV) infection and its clinical meaning.</p><p><b>Methods</b>: Total 28,339 women attending our hospital for routine gynecologic care underwent Papanicolaou test (PAP test) and high-risk HPV tests. Biopsies were taken from some women and their results were compared.</p><p><b>Results</b>: The prevalence of high-risk HPV infection is 24.15%. And the women aged 20-29 years had the highest prevalence (32.3%) compared to 30-70 years (P&#60;0.05). Of the 28,339 women, 1369 (4.83%) had positive PAP test (ASCUS, LSIL, HSIL). Of the 1369 PAP-positive patients, only 16 (1.17%) were negative for HPV test. Of the 1353 patients positive on both tests, 510 (37.7%) had lesions higher than CINII on histology. Of the 1,611 patients who underwent biopsies, 350 underwent the loop electrical excision procedure, with 339 (96%) being positive for HPV test, including 16 with CINI, 48 with CINII/III, 74 with CIS, and 16 with cervical cancer. HPV test had a positive predictive value of 40.7% and a negative predictive value of 100% for higher than CINII.</p><p><b>Conclusion:</b> Although HPV test has a burden of cost, considering its high negative predictive value, HPV test should be considered for more useful screening test.</p> ]]></description>

<title>Electrocardiographic Findings in Patients with Polycythemia Vera</title> 
<description><![CDATA[ <p><i>Background: </i>The 12-lead surface electrocardiogram (ECG) is a useful tool to predict both atrial and ventricular arrhythmias via P-wave and QT measurements and its derivatives. Polycythemia vera (PV) is a chronic myeloproliferative disorder associated with cardiovascular events. The aim of this study was to assess ECG findings of patients with PV.</p><p><i>Method and materials: </i>Sixty patients with PV (34 male, mean age 58&#177;11 years) and 60 age and gender-matched healthy volunteers were enrolled into the study. From the 12-lead surface ECG, P-wave and both conventional QT measurements and transmyocardial repolarization parameters (T<sub>peak</sub>-T<sub>end</sub> interval (T<sub>p</sub>-T<sub>e</sub>) and derivatives) were evaluated digitally by two experienced cardiologists. In addition, a novel parameter, Pi was calculated digitally as the standard deviation of the P-wave duration across the 12 ECG leads.</p><p><i>Results: </i>QT duration and corrected QT interval were significantly longer in the PV group compared to healthy controls (p&#60;0.01 and p&#60;0.01, respectively). The T<sub>p</sub>-T<sub>e</sub> was longer and the T<sub>p</sub>-T<sub>e</sub>/QT ratio was significantly higher in the PV group compared to the controls. P-wave analyses showed that all P-wave parameters including Pmax, Pmin, P dispersion, and Pi were significantly prolonged in PV patients compared to the controls. The increase of both T<sub>p</sub>-T<sub>e </sub>and P max in the PV group was independent of age, BMI, diabetes and hypertension, gender, systolic blood pressure, hemoglobin, hematocrit, left atrial dimension, left ventricular end-diastolic diameter and early deceleration time in a univariate analysis of co-variance model (F=11.097, p=0.001 and F=31.537, p=0.0001, respectively).</p><p><i>Conclusion: </i>The present study demonstrated that PV may be associated with electrocardiographic abnormalities of both atrium and ventricle.</p> ]]></description>

<title>Effects of Female Sex Hormones on Clusterin Expression and Paclitaxel Resistance in Endometrial Cancer Cell Lines</title> 
<description><![CDATA[ <p>Objective: We have analyzed the association between clusterin expression in endometrial cancer cells and their resistance to paclitaxel. We also analyzed whether the effects of female sex hormones on clusterin expression by these cell lines affect their resistance to paclitaxel. Methods: The expression of estrogen receptors &#945; and &#946;, progesterone receptors AB and B, and clusterin mRNA and protein was assayed in the ECC-1 and KLE endometrial cancer cell lines by RT-PCR and Western blotting, respectively. The IC<sub>50</sub> of paclitaxel was measured in each cell line by XTT assay. Using clusterin siRNA, we analyzed the association between clusterin expression and paclitaxel IC<sub>50</sub> in each cell line. We also examined the effects of hormone treatment on cellular resistance to paclitaxel. Results: Paclitaxel IC<sub>50</sub> was significantly higher in KLE cells, which expressed higher levels of clusterin, than in ECC-1 cells, which expressed lower levels of clusterin. Conversely, incubation with clusterin siRNA significantly decreased the viability of KLE cells (P&#60;0.001), but did not alter the viability of ECC-1 cells. Incubation with estrogen tended to increase the level of clusterin expression in these endometrial cancer cell lines, although the level of clusterin expression did not correlate with that of estrogen receptors. Incubation with progesterone did not alter the levels of expression of clusterin and clusterin receptor. Incubation with estrogen and paclitaxel significantly increased the viability of ECC-1 (P&#60;0.001) but not KLE cells. Conclusion: Estrogen increases the paclitaxel resistance of endometrial cancer cell lines, by increasing clusterin expression.</p> ]]></description>

<title>Tender Papule Rising on the Digit: Pacinian Neuroma Should Be Considered in Differential Diagnosis</title> 
<description><![CDATA[ <p>Pacinian corpuscles are sensory nerve-end organs located in the deep dermis and subcutaneous tissue of the palms or soles. Pacinian neuroma is an extremely rare feature, defined as hyperplasia or hypertrophy of Pacinian corpuscles. About half of Pacinian neuromas present with point tenderness. There have been a limited number of cases reported around the world.</p><p>We observed a 45-year-old woman with an 8-month history of a tender whitish papule on her left thumb tip. Histopathologically, an enlarged hypertrophic Pacinian corpuscle in subcutaneous tissue, surrounded by numerous nerve fibers, was found. Herein, we report a case of Pacinian neuroma presenting as a tender papule on a fingertip that was clearly related to repetitive trauma at that site. This case shows that a meticulous history and histological examination can lead to an exact diagnosis and proper treatment.</p> ]]></description>

<title>Early Biventricular Molecular Responses to an Acute Myocardial Infarction</title> 
<description><![CDATA[ <p><b>Background: </b>Acute myocardial infarction (AMI) remains as one of the most common lethal diseases in the world and therefore it is necessary to understand its effect on molecular basis. Genome-wide microarray analysis provides us to predict potential biomarkers and signaling pathways for this purpose.</p><p><b>Objectives: </b>The aim of this study is to understand the molecular basis of the immediate right ventricular cellular response to left ventricular AMI.</p><p><b>Material and Methods:</b> A rat model of left anterior descending coronary artery ligation was used to assess the effect of left ventricular AMI on both the right ventricle as a remote zone and the left ventricle as an ischemic/infarct zone. Microarray technology was applied to detect the gene expression. Gene Ontology and KEGG pathways analysis were done to identify effected pathways and related genes.</p><p><b>Results: </b>We found that immune response, cell chemotaxis, inflammation, cytoskeleton organization are significantly deregulated in ischemic zone as early response within 30 min. Unexpectedly, there were several affected signaling pathways such as cell chemotaxis, regulation of endothelial cell proliferation, and regulation of caveolea regulation of anti-apoptosis, regulation of cytoskeleton organization and cell adhesion on the remote zone in the right ventricle.</p><p><b>Conclusion: </b>This data demonstrates that there is an immediate molecular response in both ventricles after an AMI. Although the ischemia did not histologically involve the right ventricle; there is a clear molecular response to the infarct in the left ventricle. This provides us new insights to understand molecular mechanisms behind AMI and to find more effective drug targets.</p> ]]></description>

<title>Clinicopathological Characteristics and Prognosis of Non-Small Cell Lung Cancer Patients Associated with a Family History of Lung Cancer</title> 
<description><![CDATA[ <p><b>Introduction: </b>Clinicopathological characteristics and prognosis of non-small cell lung cancer (NSCLC) patients with a family history of lung cancer (FHLC) have not been well established.</p><p><b>Methods</b>: Clinical records of patients with NSCLC treated at our institute from 1982 to 2010 were reviewed with special reference to family history of lung cancer and clinicopathological factors including patient's outcome. Univariate analyses of the factors between the groups of FHLC and non-FHLC were performed using unpaired two-tailed t tests or the chi-square test. The Cox proportional hazards model was used to evaluate the hazard ratio of death.</p><p><b>Results: </b>Of the 1013 NSCLC patients, 124 (12.2%) had a FHLC of whom 119 (96%) were the first-degree relatives. The frequency of early stages of lung cancer was high in both groups of FHLC and non-FHLC patients. Patients with FHLC had a significantly higher frequency of early pathological stages and a prepomderance of adenocarcinoma, and a hazard ratio of death of 0.870 (95% confidence interval: 0.599-1.263, p value: 0.465) compared with the non-FHLC patients.</p><p><b>Conclusions</b>: NSCLC patients with FHLC could be characterized by early pathological stages and preponderance of adenocarcinoma, however they were not at a decreased hazard ratio of death. These findings emphasize the importance of early detection of lung cancer and employment of less invasive therapeutic interventions.</p> ]]></description>

<title>Delayed Intracerebral Hemorrhage Secondary to Ventriculoperitoneal Shunt: Two Case Reports and a Literature Review</title> 
<description><![CDATA[ <p>Ventriculoperitoneal (VP) shunt has become a popular operation to achieve cerebrospinal fluid (CSF) diversion, but is associated with many complications. Postoperative delayed intracerebral hemorrhage is a kind of rare but severe event, which has not thus far been reported in retrospective case analyses. Here we present two cases of delayed intracerebral hemorrhage, along the path of the ventricular catheter, which occurred on postoperative days 3 and 5. We also provide a literature review regarding this rare complication.</p> ]]></description>

<title>A Randomized Clinical Trial Comparing the Effect of Rapidly Infused Crystalloids on Acid-Base Status in Dehydrated Patients in the Emergency Department</title> 
<description><![CDATA[ <p>Study objective: To compare the effect of normal saline (NS), lactated Ringer's, and Plasmalyte on the acid-base status of dehydrated patients in the emergency department (ED).</p><p>Method: We conducted a prospective, double-blind, randomized trial of consecutive adult patients who presented to the emergency department with moderate-severe dehydration. Patients were randomly allocated to blindly receive normal saline (NS), lactated Ringer's or Plasmalyte at 20 ml/kg/h for 2 hours. Outcome measures of the study were pH and changes in electrolytes, including serum potassium, sodium, chloride and bicarbonate levels at 0, 60, and 120 minutes in venous blood gas samples.</p><p>Results: Ninety patients participated in the study and were randomized to NS (30 patients), lactated Ringer's (30 patients) and Plasmalyte (30 patients) groups. Mean age was 48&#177;20 years and 50% (n=45) of the patients were female. All pH values were in the physiological range (7.35-7.45) throughout the study period. In the NS group there was a significant tendency to lower pH values, with pH values of 7.40, 7.37, and 7.36 at 0, 1, and 2 hours respectively. Average bicarbonate levels fell in the NS group (23.1, 22.2, and 21.5 mM/L) and increased in the Plasmalyte group (23.4, 23.9, and 24.4 mM/L) at 0, 1, and 2 hours, respectively. There were no significant changes in potassium, sodium, or chloride levels.</p><p>Conclusions: NS, lactated Ringer's, and Plasmalyte have no significant effect on acid-base status and all can be used safely to treat dehydrated patients in the emergency department. However, NS can effect acidosis which might be significant in patients who have underlying metabolic disturbances; thus, its use should be weighed before fluid administration in the ED.</p> ]]></description>

<title>The GHS-R Blocker D-[Lys3] GHRP-6 Serves as CCR5 Chemokine Receptor Antagonist</title> 
<description><![CDATA[ <p>[D-Lys3]-Growth Hormone Releasing Peptide-6 (DLS) is widely utilized <i>in vivo</i> and <i>in vitro</i> as a selective ghrelin receptor (GHS-R) antagonist. This antagonist is one of the most common antagonists utilized in vivo to block GHS-R function and activity. Here, we found that DLS also has the ability to modestly block chemokine function and ligand binding to the chemokine receptor CCR5. The DLS effects on RANTES binding and Erk signaling as well as calcium mobilization appears to be much stronger than its effects on MIP-1&#945; and MIP-1&#946;. CCR5 have been shown to act as major co-receptor for HIV-1 entry into the CD4 positive host cells. To this end, we also found that DLS blocks M-tropic HIV-1 propagation in activated human PBMCs. These data demonstrate that DLS may not be a highly selective GHS-R1a inhibitor and may also effects on other G-protein coupled receptor (GPCR) family members. Moreover, DLS may have some potential clinical applications in blocking HIV infectivity and CCR5-mediated migration and function in various inflammatory disease states.</p> ]]></description>

<title>Oral Infection by Staphylococcus Aureus in Patients Affected by White Sponge Nevus: A Description of Two Cases Occurred in the Same Family</title> 
<description><![CDATA[ <p><i>Introduction.</i> White Sponge Nevus (WSN) is a rare pathology with a pathogenesis on genetic basis, a benign course and a localization affecting the mucosal keratin.</p><p>WSN is usually a symptomless pathology: when pain is present, some authors reported reduction of symptoms by taking penicillin or oral tetracycline rinses, suggesting that a bacterial overinfection could be at the base of possible painful symptoms.</p><p><i>Case Report.</i> We describe 2 patients affected by WSN, father and son: they presented two different oral diseases associated with an infection by <i>Staphylococcus aureus.</i> So, we have performed a careful oral hygiene to reduce infection in the oral cavity. In the following days we prescribed 2 rinses a day with a mouthwash containing chlorhexidine digluconate at two different percentages.</p><p><i>Discussion.</i> Early diagnosis of this lesion is important, because it allows us to exclude other more serious diseases. In the most part of cases, WSN requires no treatment because of its benign and asymptomatic behaviour: up to now, no protocol of treatment for this condition was standardized. Even if WSN is a painless condition, sometime a correlated painful symptomatology was reported.</p><p><i>Conclusions.</i> In our experience, we have achieved excellent results even with chlorhexidine digluconate rinses, considering that our treated cases were both infected by <i>Staphylococcus aureus</i>.</p><p>We hypothesize that the corrugated plaques and the altered texture of the mucosa create the right conditions for the colonization and the development of microbial species such as saprophytic bacteria or fungal species.</p> ]]></description>

<title>The Simplified Edinburgh Postnatal Depression Scale (EPDS) for Antenatal Depression: Is It a Valid Measure for Pre-Screening?</title> 
<description><![CDATA[ <p>The identification of antenatal depression is critical but poorly conducted. The aim of this study was to construct a simplified depression survey scale and to verify its efficacy as a pre-screening for antenatal depression. A total of 494 pregnant women in the third trimester of gestation who had received antenatal care at Seoul St. Mary's Hospital from July 2009 to June 2010 were included. The Edinburgh Postnatal Depression Scale (EPDS) questionnaire was completed by them. The subjects were randomly divided into two groups: 250 of training set and 244 of validation set. We designed a simplified questionnaire comprising two items of EPDS using the training set. We then validated its efficacy with the training set and reaffirmed the results with the validation set. The sum of item 5 (scare or panic) and item 8 (sadness or misery) explained 75.5% of the total score of the EPDS (AUC = 0.947). Using a score of 3 as a cut-off value of the simplified scale, sensitivity was 92.4% and specificity was 86.3%. The positive and negative predictive values were 56.2% and 98.4%, retrospectively. This study suggests that the simplified EPDS can be an efficient instrument to rule out depression during pregnancy.</p> ]]></description>

<title>Adverse Event Profiles of 5-Fluorouracil and Capecitabine: Data Mining of the Public Version of the FDA Adverse Event Reporting System, AERS, and Reproducibility of Clinical Observations</title> 
<description><![CDATA[ <p><b>Objective:</b> The safety profiles of oral fluoropyrimidines were compared with 5-fluorouracil (5-FU) using adverse event reports (AERs) submitted to the Adverse Event Reporting System, AERS, of the US Food and Drug Administration (FDA).</p><p><b>Methods:</b> After a revision of arbitrary drug names and the deletion of duplicated submissions, AERs involving 5-FU and oral fluoropyrimidines were analyzed. Standardized official pharmacovigilance tools were used for the quantitative detection of signals, i.e., drug-associated adverse events, including the proportional reporting ratio, the reporting odds ratio, the information component given by a Bayesian confidence propagation neural network, and the empirical Bayes geometric mean.</p><p><b>Results:</b> Based on 22,017,956 co-occurrences, i.e., drug-adverse event pairs, found in 1,644,220 AERs from 2004 to 2009, it was suggested that leukopenia, neutropenia, and thrombocytopenia were more frequently accompanied by the use of 5-FU than capecitabine, whereas diarrhea, nausea, vomiting, and hand-foot syndrome were more frequently associated with capecitabine. The total number of co-occurrences was not large enough to compare tegafur, tegafur-uracil (UFT), tegafur-gimeracil-oteracil potassium (S-1), or doxifluridine to 5-FU.</p><p><b>Conclusion:</b> The results obtained herein were consistent with clinical observations, suggesting the usefulness of the FDA's AERS database and data mining methods used, but the number of co-occurrences is an important factor in signal detection.</p> ]]></description>

<title>Efficacy of Lamivudine or Entecavir on Acute Exacerbation of Chronic Hepatitis B</title> 
<description><![CDATA[ <p><b>Background/Aims: </b>Spontaneous acute exacerbation of chronic hepatitis B virus (HBV) infection occasionally occurs in its natural history, sometimes leading rapidly to fatal hepatic failure. We compared the effects of lamivudine (LAM) with those of entecavir (ETV) treatments in acute exacerbation of chronic hepatitis B with 500 IU/L or higher alanine aminotransferase (ALT) levels.</p><p><b>Methods: </b>Thirty-four patients with acute exacerbation were consecutively treated with LAM /ETV. Their clinical improvements were compared.</p><p><b>Results: </b>Among LAM-treated and ETV-treated patients, none showed a reduction of &#60;1 log IU/mL in HBV DNA after 1 or 3 months of treatment. Initial virological response, defined as a reduction of 4 log IU/mL in HBV DNA at 6 months, with LAM and ETV, respectively, was 83.3% and 100%. One LAM patient developed hepatic encephalopathy, but all patients in both groups survived. Twelve months after treatment, 41.6% of 24 LAM group patients switched to another drug or added adefovir to their treatment due to the emergence of LAM-resistant mutants. On the other hand, patients receiving ETV did not need to change drugs.</p><p><b>Conclusions: </b>ETV appears to be as effective as LAM in the treatment of patients with acute exacerbation of chronic hepatitis B. Clinicians should carefully start to treat these patients as soon as possible.</p> ]]></description>

<title>Cystic Lesions of the Jaws - A Clinicopathological Study of 322 Cases and Review of the Literature</title> 
<description><![CDATA[ <p>Three hundred and twenty-two patients (192 male and 130 female) with cystic lesions of the jaw were successfully diagnosed and treated. One hundred and fifty-five (48%) were radicular cysts, 80 (25%) were dentigerous cysts, 23 (7%) were odontogenic keratocyst (=keratocystic odontogenic tumor), 19 (6%) were eruption cysts, 16 (5%) were traumatic bone cysts, and 29 (9%) were non-odontogenic cysts.</p><p>There were 95 in the pediatric age group (1 month to 16 years) and 227 in the adult age group (17 years and older). Male to female ratio was 1 in the pediatric age group and 1.7 in the adult age group. The treatment modalities were: marsupialization, enucleation, enucleation with bone grafting, or resection. The distribution and characteristics of jaw cysts in children are different from those in adults. In children there is a relatively high rate of developmental cysts, whereas in adults the inflammatory cysts are more common. Following enucleation of a cystic jaw lesion, the entire surgical specimen and not only a biopsy specimen, should be examined histopathologically to prevent any possibility of an intramural squamous cell carcinoma that may be overlooked. The differences in prevalence of each type of jaw cyst during a lifetime may point toward a multifactorial polygenic pattern rather than a monogenic pattern.</p> ]]></description>

<title>Comparison of Laparoscopic and Laparotomic Surgery for the Treatment of Peritoneal Inclusion Cyst</title> 
<description><![CDATA[ <p><b>Objectives:</b> Peritoneal inclusion cyst (PIC) is defined as a fluid-filled mesothelial-lined cysts of the pelvis and it is most frequently encountered in women of reproductive age. The treatment options are observation, hormonal management, imaging-guided aspiration, image-guided sclerotherapy and surgical excision. The objective of this study is to compare between the laparoscopic and laparotomic surgery for the treatment of PIC.</p><p><b>Methods</b>: Thirty-five patients with laparoscopy and forty-eight patients with laparotomy were included in the study. We compared the perioperative and postoperative data, the complications and the recurrence between the two groups.</p><p><b>Results</b>: There was a significantly reduced mean length of the hospital stay, estimated blood loss and complication rate in the laparoscopic group as compared to that of the laparotomic group (<i>P</i>=0.037, <i>P</i>=0.047 and <i>P</i>=0.037 respectively). There was also no statistical difference of recurrence rate between thelaparoscopic and laparotomic groups on the Cox proportional hazards model (p=0.209).</p><p><b>Conclusion</b>: Our study showed that laparoscopy was superior to the laparotomy for the mean estimated blood loss, the mean length of the hospital stay and the complication rate except for the recurrence rate.</p> ]]></description>

<title>Traumatic Hemorrhage within a Cerebellar Dermoid Cyst</title> 
<description><![CDATA[ <p>Intracranial dermoid cysts with hemorrhage are fairly rare. Herein, we reported a 28-year-old female patient with a cerebellar dermoid cyst, which was found accidently on neuro-imaging after head trauma. MR scanning revealed that the lesion was located within the cerebellar vermis and was measured 3.5cm&#215;3.9cm&#215;3.0cm, with hyper-intensity on T1WI and hypo-intensity on T2WI. However, on CT imaging, it showed hyper-dense signals. It was removed completely via midline sub-occipital approach under surgical microscope. Histological examination proved it was a dermoid cyst with internal hemorrhage. In combination with literature review, we discussed the factors that might be responsible for the hemorrhage within dermoid cysts.</p> ]]></description>

<title>Improved Synthesis Strategy for Peptide Nucleic Acids (PNA) appropriate for Cell-specific Fluorescence Imaging</title> 
<description><![CDATA[ <p>Progress in genomics and proteomics attended to the door for better understanding the recent rapid expanding complex research field of metabolomics. This trend in biomedical research increasingly focuses to the development of patient-specific therapeutic approaches with higher efficiency and sustainability. Simultaneously undesired adverse reactions are avoided. In parallel, the development of molecules for molecular imaging is required not only for the imaging of morphological structures but also for the imaging of metabolic processes like the aberrant expression of the cysteine protease cathepsin B (<i>CtsB</i>) gene and the activity of the resulting product associated with metastasis and invasiveness of malign tumors. Finally the objective is to merge imaging and therapy at the same level. The design of molecules which fulfil these responsibilities is pivotal and requires proper chemical methodologies. In this context our modified solid phase peptide chemistry using temperature shifts during synthesis is considered as an appropriate technology. We generated highly variable conjugates which consist of molecules useful as diagnostically and therapeutically active molecules. As an example the modular PNA products with the complementary sequence to the CtsB mRNA and additionally with a cathepsin B cleavage site had been prepared as functional modules for distinction of cell lines with different <i>CtsB</i> gene expression. After ligation to the modular peptide-based BioShuttle carrier, which was utilized to facilitate the delivery of the functional modules into the cells' cytoplasm, the modules were scrutinized.</p> ]]></description>
