摘要
目的为分析脑卒中伴发高血压及原发性高血压患者血管紧张素转换酶基因插入/缺失(ACEI/D)多态性。方法用PCR方法对117例缺血性脑卒中(其中80例伴发高血压)及100例年龄、性别相匹配的原发性高血压患者、40例正常人ACE基因I/D多态性进行检测。结果脑缺血伴发高血压组DD基因型频率(0.44)及D等位基因型频率(0.55)显著高于高血压组(0.22和0.43)及正常人组(0.15和0.37),脑缺血组DD基因型频率(0.39)和D等位基因型频率(0.54)显著高于高血压组及正常人组。原发性高血压组与正常人组相比无显著差别。结论我国汉族人脑卒中患者ACE基因及基因型频率增加,与是否合并高血压无关,D等位基因可能是缺血性脑卒中的易感基因。
Aim\ To analyse insertion/deletion polymorphism of angiotensinconverting enzyme gene in ischemic stroke with hypertension and hypertensives.\ Methods\ A 278 bp I/D polymorphism in intron 16 of the ACE gene was examined by polymorphism chain reaction in a study of 117 ischemic stroke patients(80 cases accompanied with hypertension) and 100 hypertensives and 40 control subjects(age,sex matched each other).\ [WT5 HZ]Results\ The polymorphism of the ACE gene was categorized into three genotypes:two deletion alleles(genotype DD),heterozygous alleles(genotype ID),and two insertion alleles(genotype II).\ The frequencies of DD genotype and D alleles in ischemic stroke patients(including hypertensive patients) were significantly higher than that in hypertensives and control subjects.\ There were no difference between hypertensives and control subjects.\ Conclusion\ The results suggest that the DD genotype is associated with ischemic storke,not with hypertension.\ D alleles may be a susceptible gene to stroke in Chinese.
