内皮细胞性一氧化氮合酶基因多态性与缺血性脑卒中的相关性研究

Correlative study between polymorphism in ecNOS gene and ischemic stroke

目的 探讨大连地区汉族人内皮细胞性一氧化氮合酶 (ecNOS)基因多态性与缺血性脑卒中的关系。方法 应用聚合酶链反应对 170例缺血性脑卒中群体及 90例非脑血管病群体ecNOS基因第 4号内含子多态性进行分析。结果 在缺血性脑卒中组中 ,高血压、糖尿病、吸烟、纤维蛋白原、颈内动脉狭窄与对照组比较 ,有显著性差异 (均P <0 .0 5 )。非条件性Logistic回归分析证实 ,ecNOS基因多态性不是缺血性脑卒中的独立危险因素。结论 ecNOS

Objective To detect the relationship between ecNOS gene polymorphism and ischemic stroke in Dalian,China.Methods The polymorphism of intron 4 of ecNOS gene was analyzed in normal group(90 cases) and ischemic stroke group(170 cases) by a combination of polymerase chain reaction(PCR).Results In ischemic stroke group,hypertension, diabete mellitus, smoking, fibrinogen and internal carotid artery narrow were significantly different from those of control group(all P <0.05). The stepwise multiple regression Logistic analysis in all patients showed that ecNOS gene polymorphism was not an independent risk for ischemic stroke.Conclusion There is no association between ecNOS4a/b gene polymorphism and ischemic stroke in Dalian, China.
