| 目的探讨IL-28B基因rS8099917位点(T＞G)单核苷酸多态性(SNP)与乙型肝炎病毒(HBV)感染后病毒自然清除和疾病进展的关系。方法 采用TaqMan SNP基因分型的方法对健康人群(n=144)、感染HBV后自愈人群(n=143)、HBV持续感染人群（肝硬化患者100例，肝癌患者99例）进行IL-28B基因rs8099917位点的多态性检测。结果 基因型和等位基因频率在各组及总体均符合Hardy-Weinberg遗传平衡。486例研究对象的基因型分布：TT型占89.3%、GT占10.5%、GG占0.2%；等位基因频率：T为94.5%，G为5.5%。该位点基因型和等位基因频率在各组间及各组内不同性别间的差异均无统计学意义(P＞0.05)。以健康组为对照经性别和年龄因素调整后，TG/GG型在自愈组、肝硬化组和肝癌组的OR值(95%CI)分别为1.589(0.735 ～ 3.437)、1.351(0.550 ～ 3.316)和1.704(0.717～4.052)。各临床特征在不同性别人群中与基因型分布的相关性分析显示，肝癌组 中TG/GG型携带者r-GTⅡ阳性的风险显著高于TT型(x2=17.534，P=0.001)，OR值(95%CI)为14.821(3.227～ 68.064)，特别是在男性中该关联更为密切(x2=14.924，P=0.014)，OR值(95%CI)为45.000(2.772～730.571)。结论 IL-28B基因rs8099917位点与HBV感染后病毒自然清除可能不存在关联性，对慢性肝病进展的影响有待大样本深入分析。 |

| Objective To investigate the correlation between IL-28B rs8099917 polymorphism and the outcome of HBV infection.Methods Genotype ofrs8099917(T＞G) in IL-28B locus was determined by TaqMan SNP genotyping from 486 individuals which including 199 chronic HBV carriers (including 100 HBV-induced liver cirrhosis and 99 HBV-related HCC).143 people with selflimited infection and 144 healthy people served as controls.Multivariate analysis was used to assess the effect of IL-28B rs80999 17 SNP among all the studied groups.Results Distribution of genotype and allele of the rs8099917 locus were in accordance with Hardy-Weinberg equilibrium in different groups or with the total population.The frequencies of the rs8099917 TT,GT,GG genotypes were 89.3%,10.5% and 0.2%,and the frequency of allele T and G accounted for 94.5% and 5.5%,respectively.In respect of genotype or allele frequency,there was no significant differences found among the groups(P＞0.05).When comparing with the TT genotype,data from the multinomial logistic analysis showed that the ORs and (95%CI) of TG/GG genotypes were 1.589 (0.735-3.437),1.351 (0.550-3.316) and 1.704 (0.717-4.052),respectively.The genotype frequencies in different groups with different clinical features showed that TG/GG genotypes significantly increased the risk of r-GT Ⅱ(+) for individuals with HBV-related HCC (X2=17.534,P=0.001),with OR as 14.821 (3.227-68.064).It was particularly so for males(X2=14.924,P=0.014), with OR(95%CI) as 45.000(2.772-730.571).Conclusion IL-28B rs8099917 SNP had no correlation with the outcome of HBV infection. |
