METHODS this association study was designed as a retrospective study, including 657 patients with chronic HBV infection(CHB) and 299 healthy controls. All subjects were ethnic Han Chinese. Chronic HBV-infected patients recruited between 2012 and 2015 at the First Hospital of Jilin University(Changchun) were further classified into HBV-related HCC patients(n = 287) and non-HCC patients(n = 370). Frequency matching by age and sex was performed for each group. Human genomic DNAwas extracted from whole blood. Gene polymorphisms were identified using a mass spectroscopic method.RESULTS there were no significant differences between the genotype and allele frequencies of the rs7291971, rs5757465 and rs5757463 A3 G gene polymorphisms, and risk of CHB and HBV-related HCC. the AG genotype and G allele for rs8177832 were significantly related to a decreased risk of CHB(OR = 0.67, 95%CI: 0.47-0.96; OR = 0.69, 95%CI: 0.50-0.95, respectively) and HCC(OR = 0.53, 95%CI: 0.34-0.84; OR = 0.58, 95%CI: 0.39-0.87, respectively). A significant relationship was found between rs2011861 computed tomography, tt genotypes and increased risk of HCC(OR = 1.69, 95%CI: 1.02-2.80; OR = 1.82, 95%CI: 1.08-3.06, respectively). Haplotype analyses showed three protective and four risk haplotypes for HCC. Also, one protective haplotype was found against CHB.CONCLUSION this study indicates that the A3 G rs8177832 polymorphism is associated with a decreased risk of CHB infection and HCC, while the rs2011861 polymorphism is associated with an increased risk of HCC.展开更多
