| 目的 了解社区人群乙型肝炎（乙肝）表面抗原（HBsAg）自然清除者的分子流行病学特征及影响因素。方法 2010-2015年以武威市乙肝防治示范区人群为研究对象，进行健康体检及随访。采用巢式病例对照研究方法，选取随访期间的99例HBsAg自然清除者为病例组，316例未发生HBsAg自然清除者作为对照组。采取问卷调查、血清学和单核苷酸多态性检测等方法获取资料。结果 99例病例组中，男性45例（45.45%），女性54例（54.55%）；316例对照组中男性156例（49.37%），女性160例（50.63%）；病例组中Notch3基因rs1043994位点CC、CT和TT基因型分别占63.64%、32.95%和3.41%，对照组中分别占77.21%、21.84%和0.95%，两组间基因型分布差异有统计学意义（P=0.014）。Notch4基因rs367398位点AA、AG和GG基因型在病例组分别占11.36%、50.00%及38.64%，在对照组中分别占5.38%、43.99%和50.63%，两组间基因型分布差异有统计学意义（P=0.043）。多因素logistic回归模型分析显示，与HBsAg自然清除相关的因素包括年龄≥60岁（OR=3.14，95%CI：1.33~7.41，P=0.009）、Notch3基因rs1043994位点CT基因型（OR=1.82，95%CI：1.06~3.13，P=0.031）及TT基因型（OR=5.58，95%CI：1.05~29.59，P=0.044）、Notch4基因rs367398位点AA基因型（OR=2.89，95%CI：1.17~7.13，P=0.021）。结论 在社区人群HBsAg携带者中，年龄≥60岁、Notch3基因rs1043994位点CT、TT基因型及Notch4基因rs367398位点AA基因型有利于HBsAg自然清除。 |

| Objective To understand the molecular epidemiological characteristics and influencing factors of natural scavengers of hepatitis B surface antigen (HBsAg) in the community population. Methods From 2010 to 2015, people from the Wuwei Hepatitis B Prevention and Treatment Demonstration Zone were used as the research object to conduct health examinations and follow-up visits. Using the nested case-control study method, 99 HBsAg natural clearancers during the follow-up period were selected as the case group, and 316 HBsAg natural clearancers who did not have HBsAg natural clearance were selected as the control group. Data were collected using questionnaires, serology, and single-nucleotide polymorphism detection. Results Among the 99 HBsAg natural clearance cases, 45 cases were male (45.45%) and 54 cases were female (54.55%); among the 316 control cases, 156 cases were male (49.37%) and 160 cases were female (50.63%); the genotypes of Notch3 gene rs1043994 loci CC, CT and TT genotypes accounted for 63.64%, 32.95% and 3.41%, respectively, and the frequency in the control group was 77.21%, 21.84% and 0.95%, respectively. The difference in genotype distribution between the two groups was statistically significant (P=0.014). The distribution frequencies of the Notch4 gene rs367398 AA, AG, and GG genotypes in the case group were 11.36%, 50.00% and 38.64%, respectively. In the control group, the frequencies were 5.38%, 43.99% and 50.63%, respectively. The genotype distribution difference between the two groups was statistically significant (P=0.043). Analysis of multivariate logistic regression model showed that factors related to the natural clearance of HBsAg include age ≥60 years old (OR=3.14, 95%CI: 1.33-7.41, P=0.009), Notch3 gene rs1043994 locus CT genotype (OR=1.82, 95%CI: 1.06-3.13, P=0.031), and TT genotype (OR=5.58, 95%CI: 1.05-29.59, P=0.044), Notch4 gene rs367398 locus AA genotype (OR=2.89, 95%CI: 1.17-7.13, P=0.021). Conclusion In a community-based population of HBsAg carriers, individuals aged ≥60 years, those with the Notch3 gene rs1043994 locus (CT, TT) and the Notch4 gene rs367398 locus (AA) were more likely to experience natural clearance of HBsAg. |
