摘要: 采用特异性引物多聚合酶链式反应方法,检测了123例冠心病患者和172例健康对照者的纤溶酶原激动抑制剂1(PAI-1)基因,并同时测定血液PAI-1质量浓度和活性,体质量指数、胆固醇和三酰甘油,探讨了PAI-1基因4G/5G多态性与冠心病的相关性.结果显示,冠心病组的缺失型纯合子4G/4G型(47.2%)明显多于对照组(22.1%,P<0.05),4G/4G组的PAI-1质量浓度〔(40.87±0.99)μg/L)〕和PAI活性〔(750±350)U/L〕均高于5G/5G组〔(38.14±1.0)μg/L,(650±270)U/L,P<0.05〕.提示PAI-1基因4G/5G多态性与PAI-1质量浓度及活性具有相关性,并与冠心病的发病过程有关.

Abstract: WT5BZ]To investigate the relationship between 4G/5G polymorphism of the plasminogen activator inhibitor-1(PAI-1)gene and coronary heart disease(CHD), genotype at this polymorphism was determined in 123 cases with CHD and 172 controls by polymerase chain reaction using the allele specific primers. Plasma PAI-1 antigen level, PAI activity, cholesterol and triglyceride were measured and body mass index was calculated from all the subjects. The group of CHD had a high number of homozygotes for the deleted allele(4G/4G)of the PAI-1 gene compared with the control(47.2% vs 22.1%, P< 0.05). Mean plasma PAI-1 antigen level and PAI activity varied significantly among the 3 genotypes, being higher in 4G/4G subjects than in 5G/5G subjects 〔(40.87±0.99)μg/L〕 vs 〔(38.14±1.0)μg/L〕, 〔(750±350)U/L〕 vs(650±270)U/L, P<0.05). The PAI-1 4G/5G polymorphism correlated with PAI-1 antigen level to some extent accounts for the development of CHD.
