摘要 目的探讨缺血性脑卒中患者同型半胱氨酸(Hcy)与PON-1 Q192R基因多态性的相关性。方法采用循环酶联免疫法检测血浆Hcy浓度以及使用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法检测140例缺血性脑卒中患者(病例组)和117名健康者(对照组)PON-1 Q192R基因多态性。结果病例组和对照组平均空腹血浆Hcy浓度分别为(14.02±4.94)μmol/L和(11.64±4.18)μmol/L,两组差异有统计学意义(t=4.09,P<0.001);将病例组和对照组作为一个研究整体发现:PON-1QQ型、QR型、RR型的平均空腹血浆Hcy浓度分别是(13.34±3.91)μmol/L、(13.14±4.98)μmol/L、(13.30±4.31)μmol/L,经方差分析,PON-1各基因型间血浆Hcy浓度差异无统计学意义(F=0.033,P=0.967)。结论血浆Hcy浓度升高与缺血性卒中有关,并且缺血性脑卒中患者Hcy与PON-1 Q192R基因多态性无关。 Objective To investigate the correlation between genetic variants in PON-1 Q192R and homocysteine (Hcy) in ischemic stroke patients.Methods Polymerase chain reaction-restrictionfragment length polymorphism (PCR-RFLP) was used to explore PON-1 Q192R gene polymorphism in the 140 patients with ischemic stroke (cases) and 117 healthy subjects (control group).Results Plasma Hcy level was higher in the patient group[(14.02±4.94)μmol/L] compared with that in the control group [(11.64±4.18)μmol/L](t=4.09,P〈0.001). Plasma Hcy concentration was not linked to PON-1 Q192R (F=0.033,P=0.967).Conclusion Plasma Hcy level was not associated with the genotypes of PON-1 Q192R.
