Objective To study the changes of platelet function in patients with hypertensive disorder complicating pregnancy (HDCP). Methods Forty non-pregnant women, 40 normal late pregnant women and 50 women with HDCP were in cluded in this study. Platelet count were determined by cell-DYN, the platelet alphagranule membrane protein (GMP-140) by radio-immunoassay and thrombosis bla smixgenz (TXB_2) and ?tissue platelet protein (?-tg) by ELISA. Platelet aggregation rate (Pagt) and pletelet adhesion rate (PADT) were also measured. Results The platelet count in non-pregnant, late pregnant and HDCP group were (206?48)?109/L, (204?52)?109/L and (172?51)?109/L, respectively, and that in the HDCP group was significantly lower than the other two. The levels of GMP-140, TXB_2, ?-TG, PAdT and PAgT were (7.9?2.8) ?g/L, (73.6?40.8) ng/L, (16.3?9.5) ?g/L, (18?9)% and (28?10)% in the non-pregnant group, (12.2?3.8) ?g/L, (80.0?39.6) ?g/L, (18.5?9.8) ?g/L, (20?8)% and (29?10)% in the late pregnant group and (25.1?3.8) ?g/L, (107.6?32.8) ng/L, (23.9?9.2) ?g/L, (30?10)% and (40?12)% in the HDCP group. All the above values in the HDCP group were significantly higher than those in the other two groups (P

Objective To study DNA damage induced by chlorinated drinking water by-product MX.Methods Hu-man hepatocellular carcinoma cell line HepG2cells was selected as target cells to test the DNA damage induced by MX using single cell gel electrophoresis assay.In this study,the cells were treated with MX at final concentrations of10,30,100and300?mol/L.DMSO and hydrogen peroxide were administered as solvent control and positive control respectively.Results MX induced DNA single strand breaks at the concentrations of30,100and300?mol/L.The length of DNA migration induced by MX increased significantly in comparison with the solvent control(DMSO)in a dose-response manner.Conclusions Chlorinated by-product MX in drinking water could induce obvious DNA damage to human hepatocellular carcinoma cell line HepG2cells.

Tumor cell plasticity, including epithelial to mesenchymal transition (EMT) and its reverse program, mesenchymal to epithe-lial transition (MET), regulates circulating tumor cells and carcinoma metastasis. Twist is overexpressed in rhabdomyosarcoma, breast cancer, gastric cancer, and other tumors. Twist, as a transcriptional factor, cross-talks with multiple signaling pathways, forming a com-plex network to participate in the regulation of EMT/MET in circulating tumor cells, which in turn promotes metastasis of tumor cells. Therefore, monitoring the level of Twist and epithelial–mesenchymal phenotypic molecules is important as it may be beneficial for in-creasing the detection ratio of circulating tumor cells as tumor biomarkers and for evaluating the effects of anticancer drugs.

AIM: To study the protective effects of intravenous (iv) CGRP on myocardial injury in rat.

Two hours later, serum CK, LDH, MDA and SOD levels were measured, MDA and SOD in myocardial tissue were tested, and myocardial tissue structures were observed. RESULTS:(1) Serum MDA and tissue MDA levels increased significantly and serum SOD and tissue SOD decreased significantly in injury group, in the CGRP treated group, the above changes were reversed (P

Background:Irritable bowel syndrome( IBS ) is one of the most common functional gastrointestinal disorders. Analyzing the regional differences of symptomatic profiles may provide guidance for the diagnosis and treatment of IBS. Aims:To preliminarily investigate the symptomatic characteristics of IBS patients in Fujian province,China for the reference of diagnosis and treatment of the disease. Methods:A total of 703 IBS out-patients based on the RomeⅢcriteria and presented to the gastroenterological clinic of 15 tertiary hospitals in Fujian Province,China from Jun. 2011 to Apr. 2012 were enrolled in a face-to-face survey. The questionnaire mainly included demographic data,course of the disease, and clinical symptoms. Results:In 703 IBS patients,the ratio of male to female was 1:1. 3,and the peak of age was 35-45 years(32. 4%). More than half of the patients were diarrhea-predominant IBS(IBS-D,58. 2%),while constipation-predominant IBS( IBS-C)accounted for 22. 6% of the patients. Abdominal pain/discomfort,abdominal distention and abnormal defecation,including diarrhea,constipation,feeling of incomplete defecation and mucous stool were the most important lower GI symptoms. In the four subtypes of IBS,the symptoms of mixed IBS( IBS-M)were most serious( P<0. 05). Compared with IBS-C,abdominal pain was more severe in IBS-D and IBS-M(P<0. 05),however,abdominal distention was more severe in IBS-C than in IBS-D(P<0. 05). About one third of the patients(32. 9%)were overlapped with upper GI symptoms,and the most common upper GI symptoms were postprandial fullness and eructation. Sixty-eight (9. 7%)patients were overlapped with functional dyspepsia. Conclusions:In Fujian Province,China,more than half of the IBS patients were IBS-D. The symptomatic profiles are different between different subtypes of IBS. Some of the IBS patients may be overlapped with upper GI symptoms or functional dyspepsia.

This study was aimed to evaluate effect of Qinghua Granules (QHG) on glycometabolism, pancreatic islet function and oxidative stress in type-2 diabetics with heat syndrome. A total of 60 cases of type-2 diabetics with heat syndrome (according to the Syndrome Element Syndrome Differentiation) were enrolled in the clinic of the Department of Endocrinology and Metabolism, Shuguang Hospital Affiliated to Shanghai University of Tradi-tional Chinese Medicine. The average age of enrolled cases was (57.9 ± 6.9) years. Enrolled cases were randomly divided into the treatment group and the control group. The original hypoglycemic plan was continued to use. In the treatment group, QHG was administrated. And in the control group, placebo was given. The administration dosage in both groups was one package per day. The treatment course was 12 weeks. The fasting and postpran-dial (120 min after standard meal) blood samples before and after medication were collected. The main evalua-tion indexes were fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and hemoglobin A1c (HbA1c). The secondary evaluation indexes were homeostasis model assessment (HOMA2-%B, HOMA2-%S, HOMA2%-IR), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), maleic dialdehyde (MDA), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL). The anal-ysis of variance was used in the comparison of efficacy between two groups . The results showed that HbA1c in the treatment group was obviously reduced, and HOMA2-%B was obviously increased. There was no significant changes in the control group ( P = 0 . 044 , P = 0 . 016 ) . In the treatment group , SOD increased obviously , MDA reduced obviously. There was no significant change in the control group. There was difference b etween two groups (P = 0.011, P = 0.049). There was no change on blood lipids or other evaluation indexes. It was conclud-ed that QHG is effective in the improvement of glycometabolism, islet β-cell functions and oxidative stress in type-2 diabetics with heat syndrome .

Objective:To investigate the recognition and injury prevention strategies of hepatic artery variations during hepatic portal lymphadenectomy. Methods:A retrospective analysis was performed, and 12 patients of hepatic arterial variation among 62 pa-tients with hepatic portal lymphadenectomy were the subjects. The study was conducted in the First Affiliated Hospital of Bengbu Medi-cal College between January 2013 and July 2014. The intraoperative treatment and postoperative complications were recorded. Results:Among 12 cases of hepatic artery variation, we found the following cases:3 cases (25.0%) of Michels' Type III, 2 cases (16.7%) of Mi-chels' Type VI, 1 case (8.3%) of Michels' Type IX, 1 case (8.3%) of Hiatt's Type 6, 2 cases (16.7%) of spatial location variation between right hepatic artery and hepatic duct, 2 cases (16.7%) of left and right hepatic artery originating from a common hepatic artery, and 1 case (8.3%) of right hepatic artery originating from the gastroduodenal artery. No injury of hepatic artery occurred. Two cases had post-operative complications, including 1 case of pancreatic leakage and 1 case of incision infection;postoperative hemorrhage, bile leakage, hepatic abscess did not occur in these two cases. Patients recovered well in general. Conclusion:Hepatic arterial injury can be signifi-cantly reduced by the following:increased familiarity with the various types of hepatic artery variations;complete imaging examina-tions for inspection and evaluation before surgery;and careful and meticulous operations in surgery.
