摘  要:目的:了解载脂蛋白E(ApoE)基因多态性与脑梗塞之间的关联。方法:应用聚合酶链反应-限制性片段长度多态性分析,对120例脑梗塞及120例正常对照的ApoE基因多态性进行分析。结果:脑梗塞组与对照组相比,ε3/3基因型频率(0·6917vs0·8333,P=0·015)及ε3等位基因频率显著降低(0·7708vs0·8958,P=0·000);ε4等位基因频率显著增高(0·1500vs0·0667,P=0·005)。结论:ApoEε3/3基因型及ε3等位基因可能是脑梗塞的保护因素,ε4等位基因可能是脑梗塞的危险因素。Objective: To detect the relationship between Apo E gene polymorphism and cerebral infarction. Methods: The polymorphism was analyzed in cerebral infarction (CI) group (120 cases) and in normal control group (120 cases) by polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) technique. Results: in contrast to the control group, the frequencies of the Apo E gene typeε3/3 (0.6917 vs 0.8333, P = 0.015) and the alleleε3 (0.7708 vs 0.8958, P = 0.000) were significantly low in the CI group; and the frequencies of the allele ε4 (0.1500 vs 0.0667 P = 0.005) was significantly high, Conclusions: The Apo E gene type ε3/3 and the allele ε3 are probably the protective factors and the allele ε4 is probably the risk factor of cerebral infarction.
