Objective:To evaluate the association between rs2294008 C>T polymorphism of prostate stem cell antigen (PSCA) gene and the risk of gastric cancer in East Asian by using Metaanalysis.Methods:A computer-based online search was performed in PubMed,Web of Science,Cochrane Library,Google Scholar,China National Knowledge Infrastructure,Chinese BioMedical Literature database,VlP database and Wanfang database.The case-control studies about the association between PSCA rs2294008C>T polymorphism and gastric cancer in East Asian before June 6,2016 were collected.The literatures were screened according to the inclusion and exclusion criteria,and the data were extracted after the quality analysis.The Meta-analysis was performed by STATA 14.1 software,and the odds ratio (OR) and 95% confidence interval (CI) were calculated.Furthermore,the subgroup analysis and Metaregression analysis were used to evaluate the confounding factors,and the sensitivity analysis and publication bias test were performed.Results:A total of 13 case-control studies contained 13 667 patients and 11 868 health controls were included.Meta-analysis showed that the carriers with PSCA rs2294008 CT and TT genotypes had significantly higher risk of gastric cancer as compared with other genotype (OR =1.68,95% CI:1.43-1.96).The polymorphism distribution of PSCA rs2294008 was significantly different among Chinese,Japanese and Korean populations (P =0.001).Subgroup analyses showed that the risk of gastric cancer on the carriers with PSCA rs2294008CT and TT was significantly increased in Chinese (OR =1.36,95% CI:1.23-1.49,P =0.004),Japanese (OR =2.61,95% CI:2.22-3.07,P =0.001) and Korean populations (OR =2.04,95% CI:1.28-3.27,P =0.012) compared with rs2294008 CC.The sub-group analyses also showed that there was no significant difference in the risk of gastric cancer between the controls from hospitals (OR =1.74,95% CI:1.23-2.44) and ones from communities (OR =1.64,95% CI:1.40-1.93).The Meta-regression found the differences in countries and control sources were not the major contribution to the heterogeneity in this analysis (P =0.163,P =0.381).The Begg's funnel plots showed no publication bias (corrected P =0.053),and the sensitivity analysis confirmed the data were steady (OR =1.54,95% CI:1.45-1.64).Conclusion:The polymorphism of PSCA rs2294008 C>T is closely associated with the risk of gastric cancer in East Asia.
Objective To explore the role of Par6 in the development of glioma by analysis of the expression of Par6 in glioma tissue. Methods 70 cases of human glioma tissue with different clinical period and differentiation histological type and 20 cases of normal brain tissue were selected.The protein of Par6 was detected by immunohistochemistry. Results Compared with normal brain tissue,the expression of Par6 protein in glioma tissue decreased significantly (P<0. 05).The expression level of Par6 was lower at stageⅢ~Ⅳthan that atⅠ~Ⅱ(Ⅰ~ⅡvsⅢ~Ⅳ;P=0.008) . Conclusion The expression of Par6 in glioma tissue decreased,and Par6 was involved in the development and progression of glioma,which was markedly correlated with clinical stage.
OBJECTIVE To evaluate the effects of atorvastatin on adipocyte fatty acid binding protein(AFABP)secretion and expression induced by oxidized low density lipoprotein(OxLDL)in adipocytes.METHODS Subcutaneous adipose tissues were collected from normal rabbits for adipocytes culture.The adipocytes were exposed to OxLDL and atorvastatin at different concentrations.AFABP concentrations in adipocytes culture supernatant were measured by ELISA.The levels of AFABP and PPARγ mRNA in adipocytes were measured by semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR)studies.RFSULTS The OxLDL in low concentrations stimulated adipocytes release of AFABP;furthermore,OxLDL increased AFABP and PPARγ,mRNA expressions of adipocytes in a dose-dependent manner.The treatment of adipocytes with atorvastatin ihhibited AFABP mRNA expression induced by OxLDL and reduced release of AFABP in adipocytes with a dosedependent manner.CONCLUSION These findings indicated that atorvastatin may inhibit AFABP expression and secretion induced by OxLDL in adipocytes which might be of significance for the prevention and treatment of atherosclerosis.

Objective: To establish diabetic model in New Zealand rabbits and study the relationship between nitric oxide(NO) pathway and diabetic nephropathy.Methods:Two groups of New Zealand White rabbits received regular rabbit chow (the normal control) or high fat high sucrose diet for 4 months. The levels of plasma insulin and glucose were investigated. The level of renal NO and the activity of renal NO synthase (NOS) were measured besides morphological observation. Results:Glomerular lesions in test group involved mesangial cell proliferation trend of K-W node and fibrin cap and accumulation of mesangial matrix and thickness of glomerular membrane basement.There were still wall thickness and cavity stricture in renal resistant vasculature.Renal NO level and NOS activity were higher in test group than in control group(P0.001). There was an elevation of the kidney/body weight in the early stage of the diabetes(P0.05)as well as a great amount of proteinuria(P0.05).The creatinine clearancerate(CCr) increased apparently(P0.001). Conclusion:New Zealand White rabbits could be used to establish the model of diabetes; Nitric oxide might be the main inductive mediator of the glomerular hyperfiltration in early diabetes.
