Objective To evaluate the association between methylenetetrahydrofolate reductase gene (MTHFR) C677T polymorphism and diabetic kidney disease in Chinese population.Methods After searching the related literatures from PubMed,Medline,EMBASE databases and common Chinese journal literature databases,meta-analysis was performed to assess the association of MTHFR C677T polymorphism with diabetic kidney disease according to the principles of systematic review based on the recessive model and dominant model respectively.Fixed effect model (M-H) was used to pool odd ratio (OR) after heterogeneity test.The Begg and Egger analysis were conducted to evaluate the publication bias.Results 10 literatures including a total of 2018 cases were included in the metaanalysis.No significant heterogeneity was detected.Data were pooled by fixed effect model.The total OR was 2.41 (95％CI=1.85～3.13) and 2.33 (95％CI=1.82～2.98) in recessive and dominant models respectively.No obvious publication bias was observed by Begg and Egger analysis.Conclusions The T allele of C677T polymorphism in MTHFR gene is positively associated with diabetic kidney disease in Chinese population.

Objective To set up a new method,which is sensitive,low cost,rapid and suitable for clinical application for FTO gene rs9930506 variant genotyping basing on high resolution melting (HRM) platform,and to preliminarily put into practice in susceptibility analysis for metabolic syndrome (MS) in Beijing.Methods Unlabelled probe with C3-spacer block specific for rs9930506 variant has been designed according to the Refseq from GenBank.With LC-Green plus dye pre-mixed,we scanned the signal for the genotype analysis after PCR amplification and HRM reaction.Restriction fragment length polymorphism (RFLP) and PCR-sequencing methods were designed as 2 control genotyping methods for the evaluation of accuracy and convenience.Afterwards,the HRM-based method was put into practice in metabolic syndrome patients (n =500) and control groups (n =500) for rs9930506 genotyping,and primarily study the association between rs9930506 and MS.Results All the 3 methods could genotype rs9930506 appropriately,although the 2 control methods seemed to be a little time-inefficient.The call rate of HRM-method was 100％ and sampling accuracy reached 99.3％ according to sequencing results.In the MS group,AA,AG and GG genotypes were found in 290,185 and 25 cases,respectively.And in the control group,those were found in 344,138 and 18 cases.No genotype distribution difference was detected between control group and HapMap-CHB data (P =0.520 ).The genotype distributions were all in Hardy-Weinberg equilibrium in each group.AA genotype of rs9930506 seemed to reduce the risk for MS( OR =0.626,95％CI =0.483-0.812).Conclusions The AA genotype of rs9930506 variant in FTO might be a protective factor for MS in Beijing population.The susceptibility related genotyping in clinical samples could be more rapid,precise and inexpensive with the development of HRM in genotyping.

To study the toxicokinetics of bakuchiol, hepatic and renal toxicity in rats after single oral administration of Psoraleae Fructus and combined with Glycyrrhizae Radix et Rhizoma, in order to provide scientific evidences for clinical safe medication use. A total of 35 SD rats were randomly divided into seven groups: vehicle (distilled water) control group, Glycyrrhizae Radix et Rhizoma group, positive control (aristolochic acid A) group, Psoraleae Fructus (40 g x kg(-1)) group( both male and female rats), Psoraleae Fructus and Glycyrrhizae Radix et Rhizoma (40 +20) g x kg(-1) group (both male and female rats). HPLC-UV method was used to determine the concentration of bakuchiol in rat plasma at different time points after single oral administration. Plasma alanine transaminase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), plasma creatinine (Cr), N-acetyl-β-D-glucosaminidase (NAG) and kidney injury molecule 1 (Kim-1) were measured after administration for 24 h. The main toxicokinetics parameters of bakuchiol in rats exert significantly gender difference. When Psoraleae Fructus combination with Glycyrrhizae Radix et Rhizoma, the total area under the plasma concentration-time curve( AUC), C(max), and plasma clearance (CL) of bakuchiol were increased, respectively; CL, half-life (t½) were decreased, and T(max) were prolonged. The biochemical indicators (including ALT, AST, BUN, Cr and KIM-1 level) in different dose of Psoraleae Fructus groups, were found no statistically significant difference when compared with vehicle control group. The level of NAG in both Psoraleae Fructus and compatibility with Glycyrrhizae Radix et Rhizoma groups were significant increased (P < 0.05). There are obvious effects on toxicokinetics of bakuchiol in rats when Psoraleae Fructus combined with Glycyrrhizae Radix et Rhizoma. Renal toxicity induced by Psoraleae Fructus at high dose was observed after single oral administration and no liver damage in rats was found.

Objective To study the characteristics of event-related potentials P300 in patients with anxiety disorder(AD). Methods P300 tests were carried out in 30 patients with AD and 30 healthy adult controls. ResultsPatients with AD had significantly delayed P3 latency ([326?16] ms vs [339?19]ms, P

ObjectiveTo investigate the association between the common variant rs1512268 single nucleotide polymorphism(SNP) of NKX3.1 gene and the risk of prostate cancer,and to explore its interaction with related risk factors.MethodsTotally 122 patients with prostate cancer and 105 age matched male people (prostatic specific antigen ＜ 4 μg/L,without family history of prostate cancer) as control group were enrolled.Polymerase chain reaction - high resolution melting curve(PCR - HRM) combined with gene sequencing methods were used to determine the distribution of allele and genotype frequencies of the rs1512268 SNP.ResultsThe distributions of GG,AG,AA genotypes were 42 cases(33.4％),66 cases(54.1％),14 cases(11.5％) in patients with prostate cancer,and 45 cases(42.9％),51 cases(48.6％),9 cases(8.6％) in healthy control,respectively.There were no significant differences in the distribution of genotype(x2 =1.70,0.69,0.52) and allele frequency (x2 =1.575) between the two groups(P＞ 0.05).The different genotypes of rs1512268 of NKX3.1 gene were not associated with age,Gleason score,PSA levels and clinical stage of prostate cancer (P＞0.05). Conclusions rs1512268 SNP of NKX3.1 gene is not obviously associated with prostate cancer and may be not the genetic risk factor in Chinese.

Objective This study is designed to determine whether an association exists between single nucleotide polymorphism (SNP) variant rs2252673 of insulin receptor(INSR) gene and polycystic ovarian syndrome (PCOS) in Han Chinese in order to identify INSR as a genetic susceptibility factor for PCOS.Methods A total of 224 women with PCOS,192 controls and 672 participants consisting of 224 trios (mother,father and offspring with PCOS) were recruited from the Hospital for Reproductive Medicine Affiliated to Shandong University,from July 2007 to April 2013.Genomic DNA was extracted according to the manufacturer' s protocol.SNP rs2252673 of INSR gene was amplified by PCR and then sequenced on an automated sequencer.Moreover,clinical and metabolic features of the patients with PCOS were compared according to the genotypes.The subjects were divided into twot groups according to body mass index (BMI),and then the results were compared between two groups.And the transmitted disequilibrium test (TDT) was applied for data analysis.Results (1) There were three kinds of genotype of CC,CG and GG.Genotype frequencies of rs2252673 were 8.0％,38.8％,53.1％ and 14.6％,42.2％,43.2％ in the PCOS group and the control group,respectively.The allele frequencies of C and G were 27.5％,72.5％ and 35.7％,64.3％ in the PCOS group and the control group,respectively.There were statistical differences in genotype frequencies and allele frequencies between two groups (all P＜0.05).(2)No significant differences were observed in the different genotype according to clinical and metabolic characteristics of women with PCOS (P＞0.05).But when merging the genotype CG and GG,carriers of the CG and GG genotypes in women with PCOS were slightly associated with total cholesterol (TC) levels (t=2.072,P=0.048) and lower high-density lipoprotein (HDL) levels (t=2.274,P=0.026).Although statistical significance was not achieved,there was an increased tendency in fasting blood glucose (FBG) and fasting insulin (FINS) levels in CG and GG genotypes in PCOS cases.(3)Between the obesity and the non-obesity with PCOS,there was no statistical significance in the genotype and allele frequencies (x2=0.054,P=0.974; x2=0.022,P=0.883).(4)The results of families based analysis shown that genotype distribution of the SNP rs2252673 was in Hardy-Weinberg equilibrium (P＞0.05).After the TDT,the G allele in SNP rs2252673 was over transmitted in families (transmitted∶ non-transmitted=120∶ 88; x2=4.923,P=0.027).There was a transmitted disequilibrium in rs2252673,which implies the association of INSR and PCOS were independent of population stratification.Conclusions There were a association between the SNP variant rs2252673 of INSR gene and the susceptibility to PCOS in Han Chinese women,which was independently of body mass index.The carrier of G allele frequency of rs2252673 may have higher risk of PCOS.
