摘 要:目的应用Meta分析探讨中国汉族人群ApoE基因多态性与冠心病易感性的关联。方法对入选文献的基因型进行哈代一温伯格遗传平衡检验。根据异质性检验结果选用固定或随机效应模型。采用RevMan5.1和Stata11.0软件进行Meta分析。结果共纳入符合条件的文献25篇,纳入文献无明显发表偏倚。以基因型ε3/3为参照,ε2/2+ε2/3合并统计量OR(95%CI)为1.10(0.93,1.30),P=0.25,无统计学意义;ε3/4+ε4/4合并统计量OR(95%CI)为2.03(1.66,2.48),P=0.00,与冠心病相关;以等位基因ε3为参照,ε2 vsε3OR(95%CI)为1.10(0.95,1.27),P=0.21,无统计学意义;ε4 vsε3OR(95%CI)为1.95(1.71,2.23),P=0.00,与冠心病相关。结论载脂蛋白ε2/2+ε2/3及ε2与冠心病无显著关联,而ε4/4+ε4/3及ε4可能是冠心病的危险因素。Objective To evaluate the associations between gene polymorphisms in apolipoprotein E (ApoE) and coronary artery disease (CAD) in China Han population using the recta-analysis. Methods Hardy-Weinberg equilibrium (HWE) test was used to check genetic equilibrium among genotypes for the selected literature. A fixed or random effect model was used on the basis of heterogeneity. This recta-analysis was performed by Review Manager 5. 1 and Stata 11.0 Software. Results Twenty-five reports met the inclusion criteria for this meta-analysis. Compared with the ε3/3 genotype, the pooled 0R(95%CI) of ε2/2 +ε2/3 was 1. 10(0.93, 1.30), and P =0.25, with no statistical significant. The pooled 0R(95% CI) of ε3/4 + ε4/4 was 2.03( 1.66, 2.48), and P =0.00, which were associated with CAD. Compared with the ε3 allele, the ε2 had no statistical significant, with OR (95% CI) = 1.10(0.95, 1.27), P =0.21. However, the ε4 increased CAD risk, with 0R(95% C1)of 1.95(1.71, 2. 23) , and P=0.00. Conclusion The ε2/2 +ε2/3 and ε2 were not associated with CAD. However, ε3/4 + ε4/4 vsε3/3 and ε4 might be the risk factors for CAD.
