To evaluate the association between hypertensive cerebrovascular stroke and renin-angiotensin system gene polymorphism from Chinese cohort.
The polymorphisms of angiotensinogen(AGT) and angiotensin-converting enzyme(ACE) from 257 cases of simple essential hypertension(EH) and 218 cases of hypertensive stroke(131 hemorrhagic cases and 87 ischemic cases were detected by PCR-RFLP.
The frequencies of DD genotype and D allele of ACE gene in ischemic stroke were significantly higher than those in hemorrhagic stroke and EH, and the odds ratios(OR) of DD/II genotype were 3.25(2.20-4.79) and 2.87(2.03-4.06), while the OR of D/I allele were 1.83(1.38-2.43) and 1.69(1.27-2.24) respectively. Otherwise, there was no difference in frequency distribution of Met235Thr mutation polymorphism and DD+TT/non DD non TT combined among the three groups.
The I/D polymorphism of ACE gene may be one of the risk factors and susceptible genetic markers for ischemic stroke with essential hypertension in Chinese.
评估中国队列中高血压性脑血管卒中与肾素-血管紧张素系统基因多态性之间的关联。
采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)检测257例单纯原发性高血压(EH)患者和218例高血压性卒中患者(131例出血性病例和87例缺血性病例)的血管紧张素原(AGT)和血管紧张素转换酶(ACE)基因多态性。
缺血性卒中患者ACE基因的DD基因型和D等位基因频率显著高于出血性卒中和EH患者,DD/II基因型的比值比(OR)分别为3.25(2.20-4.79)和2.87(2.03-4.06),而D/I等位基因的OR分别为1.83(1.38-2.43)和1.69(1.27-2.24)。此外,三组间Met235Thr突变多态性及DD+TT/非DD非TT组合的频率分布无差异。
ACE基因的I/D多态性可能是中国原发性高血压患者发生缺血性卒中的危险因素和易感遗传标记之一。
