摘要: 目的探讨肿瘤坏死因子α(TNFα)1031T>C基因多态性与幽门螺杆菌易感性的关系。方法计算机检索CNKI、维普数据库、万方数据库、Pubmed数据库、Cochrane 图书馆及Embase数据库,查找TNFα1031T>C基因多态性与幽门螺杆菌易感性相关的病例对照研究。采用STAT 12.0进行数据分析。应用OR及其95%CI表示其关联强度。结果共纳入10项病例对照研究,2 328例患者。Meta分析结果显示,与健康人群相比,累加遗传模型(TT vs  CC,OR=0.61, 95%CI=0.44~0.85,P=0.003)与显性遗传模型(TT+CT vs CC,OR=0.61,95%CI=0.44~0.84,P=0.002)可能会降低Hp感染的风险,差异具有统计学意义(P<0.05)。而等位基因模型(T vs C,OR=0.92,95%CI=0.82~1.02,P=0.106)和隐性遗传模型(TT vs CC+CT,OR=0.96, 95%CI=0.84~1.09,P=0.504)两组间差异无明显统计学意义(P>0.05)。结论TNFα1031T>C基因累加遗传模型中TT基因频率和显性遗传模型中TT+CT基因频率的增加是Hp感染的保护因素。该结论还需更多大样本多中心的研究论证。

Abstract: ObjectiveTo investigate the association between TNFα 1031 T>C polymorphisms and helicobacter pylori(H.pylori) infection. MethodsPublished literatures within CNKI, VIP Database, Wanfang Database, PubMed, Embase, and the Cochrane Library were searched. Data were analyzed with the Stata12.0 software package using pooled odds ratios (ORs) with 95% confidence intervals (CI).ResultsA total of ten studies involving 2 328 patients were included in this study. The results of metaanalysis showed that TNFα 1031 T>C polymorphisms was associated with decreasing H.plylori infection(TT vs CC,OR=0.61,95%CI=0.440.85,P=0.003; TT+CT vs CC,OR=0.61,95%CI=0.440.84,P=0.002). However, there was no significant difference between allele model(T vs C, OR=0.92,95%CI=0.821.02,P=0.106) and recessive model(TT vs  CC+CT,OR=0.96,95%CI=0.841.09,P=0.504).ConclusionTNFα 1031 T>C polymorphisms may be associated with a decreasing risk of H. pylori infection. Further studies with different ethnicities and larger sample size are required to validate the results.
