广东籍汉族妇女N5,10-MTHFR基因和eNOS基因多态性与子痫前期和子痫相关性的研究

目的:探讨N5,10-亚甲基四氢叶酸还原酶(MTHFR)基因及内皮型一氧化氮合酶(eNOS)基因多态性与广东籍汉族妇女子痫前期和子痫发病的关系。方法:567例广东籍汉族妇女中54例诊断为子痫前期或子痫,513例为正常妊娠(对照组)。应用PCR-RFLP方法,检测567例早孕期妇女外周血MTHFR基因C677T突变和eNOS基因G894T突变,计算各基因型的相对风险率。结果:子痫前期和子痫组MTHFR C/C、C/T及T/T基因型频率分别为59.2%、20.4%及20.4%,其中T/T基因型频率显著高于对照组(5.5%)(P<0.001),并且T等位基因频率为30.6%,显著高于对照组(20.5%)(P<0.05),T/T基因型在子痫前期或子痫发病中的相对风险率为4.431。子痫前期和子痫组的eNOS基因频率与对照组无显著差异。结论:广东籍汉族妇女MTHFR基因C677T多态性可能与子痫前期或子痫发病的易感性相关,eNOS基因G894T多态性与子痫前期或子痫发病的易感性无关。

Study on the relationship between N5,10-methylenetetrahydrofolate reductase gene and endothelial nitric oxide synthase gene polymorphisms and preeclampsia and eclampsia in the Han nationality women of Guangdong

Objective:To investigate a potential association of the gene polymorphisms of N5,10-methylenetetrahydrofolate reductase(MTHFR)gene and endothelial nitric oxide synthase(eNOS)gene with preeclampsia and eclampsia in the Han nationality women of Guangdong,China.Methods:The MTHFR C677T polymorphisms and eNOS G894T polymorphisms were determined by PCR-RFLP in 54 pregnancy induced hypertensions patients and 513 normal early pregnancy women(control group).Odds ratios(OR) and 95% CI were obtained to evaluate the as...
