Effects of PNPLA3, TM6SF2 gene polymorphisms and its interactions with smoking and alcohol drinking on hepatitis B virus-associated hepatocellular carcinoma / 中华流行病学杂志

Objective To explore the SNP effects ofpatatin-like phospholipase domain which containing 3 (PNPLA3),transmembrane 6 superfamily member 2 (TM6SF2) gene,environmental effects of smoking,alcohol drinking and interaction between gene-gene,gene-environment and drinking-smoking on hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC).Methods We collected anticoagulant peripheral blood from patients of HBV-HCC,chronic hepatitis B (CHB),liver cirrhosis (LC) and from healthy controls to detect the single nucleotide polymorphism (SNP) of patatin-like phospholipase domain containing 3 (PNPLA3) gene loci rs738409 and transmembrane 6 superfamily member 2 (TM6SF2) gene loci rs58542926,using the flight mass spectrometry method.The optimal assignment value of gene polymorphisms was defined by using the online SNP stats.Hardy-Weinberg (H-W) balance was tested for SNP.Effects of the genetic and environmental factors to HBV-HCC were analyzed by using the multiple classification logistic regression method.The gene-gene,gene-smoking and alcohol drinking interaction effects were investigated by Fork-Life analysis and binary logistic regression methods.Results The frequency distribution of CHB group rs738409 loci seemed not in conformity with the H-W balance (x2=11.980,P＜0.005).Two loci frequency distributions in the other groups were all in accordandce with the H-W balance.After adjusting for influences on age and sex and comparing to the healthy group,the rs58542926 mutation appeared as OR=1.659,95％CI:1.026-2.684,P=0.039,in the HBV-HCC group.When comparing to CHB group,the HBV-HCC group presented that drinking as OR=1.680,95％CI:1.121-2.519,P=0.012.When comparing to the LC group,the ORs of drinking and smoking were 1.539 (1.071-2.213) and 1.453 (1.005-2.099) respectively,in the HBV-HCC group.When comparing to the CHB + LC group,interactions between the HBV-HCC group were found rs738409 and rs58542926 on additive model OR=1.548 (U=1.885,P=0.029) and OR=1.658 (P=0.024) on logistic regression model while drinking was rs738409 on interaction additive model with OR=1.811(U=1.965,P=0.024).As for drinking and mutation of rs738409,the multiplication model of logistic regression showed no statistically significant differences.Interaction between smoking and drinking appeared as OR=1.756 (P＜0.001) in the logistics regression multiplication model.Conclusions Factors as mutation of TM6SF2,smoking and drinking all appeared as risk factors for HBV-HCC.Mutations of both PNPLA3 and TM6SF2,together with smoking and drinking all served as risk factors for HBV-HCC.However,the mutation of single PNPLA3 appeared as a protective factor on HBV-HCC.

Objective To understand the association between two single-nucleotide polymorphism (HLA-DQ rs28567185 and rs9275572) and different outcomes of hepatitis B virus (HBV) infection.Methods A total of 825 HBV infection related cases were enrolled,and peripheral blood samples were collected from them for DNA extraction.The single-nucleotide polymorphism in HLA-DQ region were genotyped by using matrix-assisted laser desorption/ionization time of flight mass spectrometry.Logistic regression analysis was conducted to evaluate the association between HLA-DQ gene polymorphism and different outcomes of hepatitis B virus infection.Results Our study indicated that cases with HLA-DQ rs2856718G (524 cases) and rs9275572A (369 cases) had reduced susceptibility to HBV infection (OR=0.702,95％CI:0.558-0.856,P=0.001;OR=0.548,95％C1:0.365-0.847,P=0.005) and higher HBV natural clearance (OR=0.589,95％ CI:0.478-0.892,P=8.81 × 10-3;OR=0.673,95％CI:0.457-0.860,P=0.014).Moreover,rs9275572A was also associated with the lower risk of the development of hepatocellular carcinoma (OR=0.759,95％CI:0.538-0.914,P=0.041).Conclusion Our study suggested that HLA-DQ loci might be associated with the different outcomes of HBV infection in Chinese in Han ethnic group in northern China,rs2856718G and rs9275572A might be protective factors for HBV infection,HBV natural clearance and HBV-related disease progress.

The relationship between the health management and the level of consumption, concept of investment / 中华健康管理学杂志

Objective To understand the relationship between the requirement and the consumption of the health management, and provide the theoretical basis for the developing of China health management. Methods It took the survey to understand the relationship among 152 medical staffs from the six counties surrounding with Shi Jiazhuang downtown. Results 85.5%of medical staffs always and almost accept health advisory and provide health guidance. There are not the direct relationship between the requirement and the consumption(x2 = 9.39,P＞0.05 ). Health advice and guidance are not translated into the concepts of investment on the health management and disease prevention (x2 = 1.69, P＞0.05 ). The medical staffs don't realize it is important to invest on the health. Conclusions Related industries should strengthen the training on the health management, publicize this profession, promote the development of health management services and improve the national health quality.[ Key words] Health promotion ; Needs assessment; Economics

Screening of Stage-Specific Expression Genes of Spirometra erinacei-europaei Plerocercoid by mRNA Differential Display Technique / 中国寄生虫学与寄生虫病杂志

Objective To screen stage\|specific expression genes of plerocercoid of Spirometra erinacei\|europaei. Methods RNA was extracted by the acid guanidinium thiocyanate\|phenol\|chloroform from plerocercoid and adult worm of Spirometra erinacei\|europaei. Contaminated DNA in the RNA was digested by RNase\|free DNase. cDNA was synthesized by using T\-\{12\}MA, T\-\{12\}MC, T\-\{12\}MG and T\-\{12\}MT primers, and PCR was then done using the same T\-\{12\}MN and one random primers. The PCR products were fractionated on 8% denatured polyacrylamide gel, differential bands of plerocercoid found in the gel were cut out, amplified by PCR and sequenced after the gel was dried out and autoradiographed. Northern hybridization was conducted to identify the stage\|specific expression genes. Results Eleven differential bands were selected from the gel and classified into 3 kinds of gene fragments by hybridization after they were amplified by PCR. The fragments 1 and 2 were confirmed to express specifically in plerocercoid by Northern hybridization, but the fragment 3 was expressed in both plerocercoid and adult worm. When the 3 gene fragments were homologically analyzed in GenBank, the sequence which was homologous with the fragments 1 and 2 was not found, but the fragment 3 had high homology with many kinds of 28S rRNA. Conclusion The gene expression of plerocercoid was different from that of adult worm probably because they live in different hosts. Two kinds of different gene fragments in plerocercoid were identified by mRNA differential display technique.
