广西地区人群IL-6及IL-10单核苷酸多态性与HBV相关肝癌关联研究

目的 探讨广西地区人群IL-6和IL-10基因单核苷酸多态性(SNP)与HBV相关肝癌的关系.方法 采用以医院为基础的病例对照研究方法,以381例肝癌患者为病例组,340例HBsAg携带者及359例健康体检者为对照组.应用荧光定量PCR对IL-6基因-572位点,IL-10基因-819和-592位点进行基因分型.采用非条件logistic回归模型分析比较携带不同基因型人群罹患肝癌的风险.结果 IL-6基因-572位点G/C等位基因在病例组、HBsAg携带组及健康对照组中分布差异有统计学意义(P＜0.05),与CC基因型相比,携带GG基因型个体慢性HBV感染危险性增加(OR=2.171,95%CI:1.068-4.415).IL-10基因-819位点T/C等位基因在三组的分布差异有统计学意义(P＜0.05),与CC基因型相比,携带TT基因型健康个体罹患肝癌的危险性增加(OR=2.791,95%CI:1.326～5.874).携带TT基因型的HBsAg携带者罹患肝癌的风险也增加(OR=3.522,95%CI:1.707～7.266).IL-10基因-592位点A/C等位基因在三组中的分布差异无统计学意义(P＞0.05),与CC基因型相比,携带AA基因型健康个体罹患肝癌的危险性降低(OR=0.389,95%CI:0.173-0.875),携带AA基因型的HBsAg携带者肝癌的罹患风险也降低(OR=0.336,95%CI:0.154-0.734).结论 IL-6基因-572位点SNP与广西地区人群慢性HBV感染有关,IL-10基因-819位点TT基因型个体罹患肝癌的风险增加,IL-592位点从基因型个体罹患肝癌的风险降低.

Abstract：

Objective To investigate the association between single nucleotide polymorphisms (SNPs)in cytokine IL-6, IL- 10 genes and HBV-related hepatocellular carcinoma(HCC). Methods A hospital-based case-control study was conducted in 381 cases with HBV-related HCC, 340 HBsAg carriers and 359 non-tumor controls. Genotypes of-572 site of IL-6 gene and-819, -592 sites of IL-10 gene were determined by real-time polymorphism chain reaction. Unconditional logistic regression was used to estimate the odds ratios(ORs)and 95 confidence intervals(C/s). Results For the G/C alleles of -572 loci on IL-6 gene, there were significant differences between the three groups(P＜0.05). Compared with CC genotype, GG genotype increased the risk of HBV infection (OR=2.171,95% Ch 1.068-4.415), but did not seem to be associated with HCC. For the alleles of-819 and -592 site of IL-10 gene, there were significant differences between the three groups(P＜0.05). Compared with CC genotype, TT genotype increased the risks of both HCC(OR=2.791,95%CI:1.326-5.874), and HCC in HBsAg carriers(0R=3.522,95%CI: 1.707-7.266). When compared with CC genotype on -592 site, the AA genotype reduced the risk of both HCC(OR=0.389, 95% CI:0.173-0.875), and HCC in HBsAg carriers(OR=0.336, 95% CI: 0.154-0.734). Conclusion The SNPs in -572 site of IL-6 gone might be associated with the risk of HBV infection. The SNPs in -819 site of IL-10 gene increased the risk of HCC, but -592 site of IL-10 gene decreased the risk of HCC.
