摘要 目的观察汉族人群中,乙醛脱氢酶2(ALDH2)基因Glu487Lys多态性与罹患冠心病危险性之间的关联。方法收集经冠脉造影检查明确诊断且冠脉狭窄≥50%的490名冠心病患者(冠心病组)及明确排除的433名非冠心病患者(对照组),共923例纳入本项研究。ALDH2的Glu487Lys基因多态性由TaqManPCR技术测得,比较ALDH2各基因型在冠心病组与对照组的分布,并根据冠心病危险因素,对该研究进行了亚组分析。结果在所有研究对象中,ALDH2各基因型在冠心病组和对照组分布差异无统计学意义(P=0.22)。但亚组分析显示,在无饮酒史,无吸烟史,无高血压史,BMI<25(kg/m2)4个亚组中,ALDH2各基因型的分布在冠心病组和对照组中差异有统计学意义(P<0.05)。结论 ALDH2基因多态性与中国人群罹患冠心病无显著关系,在单纯无饮酒史,无吸烟史,无高血压史或BMI正常的中国汉族人群中,ALDH2基因AA型与其罹患冠心病可能存在关联。 Objective To discover the relationship between ALDH2 Glu487Lys gene polymorphism and coronary artery disease in Han population.Methods 490 patients with coronary artery disease(CHD group) which were identified by coronary angioplasty(coronary narrow ≥50%) and 433 patients without CAD were recruited from Zhongshan Hospital(control group).Taqman 5 nuclease polymerase chain reaction assay was performed to screen the ALDH2 Glu487Lys gene polymorphism.The difference of the distribution of ALDH2 gene was compared...
