载脂蛋白E基因多态性与冠心病关系的meta分析

目的 研究载脂蛋白E基因多态性与冠心病发病的关系。方法 采用随机效应模型进行meta综合分析合并率差。结果 冠心病组与对照组合并率差为E3／3基因型频率为-8．5％,ε3等位基因频率为-4．2％;而E4／3基因型频率、ε4等位基因频率则分别为10．5％和5．8％;4组数据均有统计学意义。结论 E3／3基因型者不易患冠心病,E4／4基因型携带者冠心病发病的危险性显著增加。

Meta-analysis for relationship between apoE gene polymorphism and coronary heart disease

OBJECTIVE: To evaluate relationship between ApoE gene polymorphism and coronary heart disease (CHD). METHODS: Meta-analysis was applied with a random-effect model for the collected data. RESULTS: Difference in pooled frequencies, d, of apoE genotypes E3/2, E4/2, E3/3, E4/3 and E4/4 between case and control groups were 2.3%, -0.8%, -8.5%, 10.5% and 0.9%, respectively. Difference in pooled frequencies, d, of apoE alleles epsilon2, epsilon3 and epsilon4 were -1.5%, -4.2% and 5.8%, respectively, with a statistical significance between four groups. CONCLUSIONS: apoE gene polymorphism was involved in coronary heart disease. Persons with apoE E3/3 genotype or epsilon3 allele were not susceptible to CHD, but those with apoE E4/4 genotype or epsilon4 allele had higher risk suffering from CHD than others.
