【摘要】 目的　研究GNB3基因C82 5T多态性和硝苯地平控释片降压效果的相关性。方法　收集了 5 5 4个原发性高血压患者给予硝苯地平控释片治疗 ,通过问卷调查和随访取得其流行病学的临床资料 ,用PCR RFLP法测定其GNB3基因的基因型。用线性回归和Logistic回归分析了该基因型对疗效的影响。结果　 82 5T等位基因在我们研究的高血压群体中的频率为 4 8 4 %。稍高于Siffert等报道的正常血压的中国人的T等位子频率 (42 % )。T等位子的携带者在硝苯地平控释片治疗 15d后 ,其收缩压下降幅度较CC纯合子小3 3mmHg。经多元线性回归分析两组间差别有显著性 (P<0 0 5 )。取收缩压下降值的分布曲线的上下 2 0 %分别作为疗效好与差组 ,经多元Logistic回归分析表明T等位子的携带者比CC基因型人群取得较好的收缩压治疗效果的可能性要小 ,OR值为 0 33,P =0 0 2。结论　GNB3基因C82 5T多态性和硝苯地平控释片的降压疗效相关更多还原

【Abstract】 AIM To study the relationship between the response of hypertension patients to Adalat and the C825T polymorphism of the GNB3 gene. METHODS 554 hypertension subjects were treated with Adalat. Epidemiological and clinical data were collected. Genotypes of the GNB3 gene were measured by the PCR RFLP method. Linear and logistic regression were used to analyze the association between GNB3 genotypes and the response to Adalat. RESULTS The frequency of the 825T allele in our hypertensive group (48 4%) was slightly higher than that of the normal Chinese reported previously by Siffert W et al. (42%). The average SBP decrease after 15 days of Adalat treatment of subjects with the T allele was significantly less than that of the subjects with the CC genotype (β=-3 3, P= 0 03). Using logistic regression, the subjects with the T allele were less likely to reach good treatment result compared to those with the CC genotype (OR=0 33, P =0 02). CONCLUSION The GNB3 gene C825T polymorphism is related to the response to Adalat.更多还原
