中文摘要:

目的: 探讨内皮型一氧化氮合酶 (eNOS)基因第7外显子G894T变异(Glu2 98Asp)与高血压病的关系。方法: 以人群中筛检出的、未经药物治疗的116例高血压病患者及136名血压正常者为研究对象, 运用聚合酶链反应限制性片段长度多态性(PCR RFLP)检测G894T变异。结果: G894T变异与高血压病显著相关, 894T等位基因频率高血压病组显著高于血压正常组(16.0 %∶8.8%, P=0.019), OR =1.96,95 %CI:1.14～3.37。在病例组、对照组及两组合计中, G894T变异基因型的收缩压及舒张压水平皆显著升高(P<0.05 )。用多元协方差分析调整年龄、性别、吸烟、饮酒、体重指数、甘油三酯、总胆固醇、高密度脂蛋白胆固醇后, 在病例与对照合计中, G894T变异基因型对收缩压及舒张压水平仍具有正显著影响(P<0.01)。结论: eNOS基因第7外显子G894T变异可能是该研究人群中高血压病发病的重要危险因素之一。

英文摘要:

Objective： To analyze the association between G894T (Glu298Asp) mutation at exon 7 in the endothelial nitricox idesynt hase gene and essential hyper tension. Methods： One hundred and six teen essential hypertensives without taking hypertensive medication and 136 normotensives screened from health workers in a steel factory were selected as subjects in this study. Polymerase chain reaction (PCR) and Ban restriction enzyme digestion were performed to detect the G894T mutation. Results： G894T mutation was significantly associated with essential hyper tension. The Tallele frequency in essential hypertensive group was sig nificantly higher than that in normotensive group ( 16.0% versus 8.8%, P = 0.019, OR =1.96,95% CI : 1. 143.37. The levels of systolic blood pressure and diastolic blood pressure in the G894T mutant genotypes were all significantly elevated in hypertensive, normotensive, and the total subjects (P<0.05). After adjusting factors as age, sex , smoking, alcohol drinking, body mass index, triglyceride, serum total cholesterol, serum high density lipoprotein cholesterol by analysis of multiple covariance, significant positive effect of the G894T mutant genotypes on blood pr essure in the total subjects ( P<0.01) was noticed. Conclusion： This study suggested that the G894 Tmutation in the endothelial nitric oxide synthase gene might serve as a major risk factor of essential hypertension in this study population.
