摘要: 目的 探讨G蛋白β3亚单位基因C825T多态性与氨氯地平降压疗效的关系。方法 采用多聚酶链式反应结合限制性内切酶片段长度多态分析方法,检测147例健康人和321例原发性高血压患者的G蛋白β3亚单位C825T多态性,其中48例高血压患者口服氨氯地平4周。结果 1)高血压组G蛋白β3亚单位C825T多态性中基因型频率(CC28.7%、CT52.0%、TT19.3%)、等位基因频率(C54.7%、T45.3%)与正常对照组基因型频率(CC27.2%、CT46.9%、TT25.9%)、等位基因频率(C50.7%、T49.3%)比较差异无统计学意义;2)CC基因型的收缩压降低值〔(4.93±2.26)kPa(37.00±16.97)mmHg〕明显高于CT+TT基因型〔(2.99±1.41)kPa(22.40±10.60)mmHg〕(P<0.05)。结论 G蛋白β3亚单位基因C825T多态性与氨氯地平的降压疗效相关,而与原发性高血压无关。

Abstract: Objective To investigate the relationship between Gprotein β3 subunit gene polymorphism and the efficacy of antihypertensive treatment with amlodipine.Methods Polymerase chain reaction combined with restriction enzyme digestion was used to detect the polymorphism of Gprotein β3 subunit gene in147 individuals as normotensive control and 321 hypertensive patients.48 hypertensive patients were treated with amlodipine for 4 weeks.Results 1) There were no significant differences of the GNB3 gene C825Tpolymorphism genotypes and alleles between hypertensive patients(CC28.7%, CT 52.0%, TT 19.3%(C54.7%, T 45.3%) and normotensive controls(CC27.2%, CT 46.9%, TT 25.9%, C50.7%, T 49.3%).Mean reduction in systolic blood pressure were significantly greater in CCgenotype((4.93±2.26)kPa(37.00±16.97)mmHg) than in CT+TTgenotype((2.99±1.41)kPa(22.40±10.60)mmHg)(P<0.05).Conclusion The C825Tpolymorphism of Gprotein β3 subunit is related to the efficacy of amlodipine but not to essential hypertension.
