摘要: 目的: 研究血管紧张素转化酶(angiotensinconverting enzyme, ACE)基因多态性与依那普利降压疗效的相关性。方法: 采用聚合酶链式反应-限制性片断长度多态性(polymerase chain reaction-restriction fragment length polymorphism, PCR-RFLP)对68 例原发性高血压患者进行ACE 基因型分析, 根据ACE 三种基因型DD 型、ID 型和Ⅱ型将受试者分为三组, 所有受试者每天服用依那普利20 mg进行2 周的降压治疗, 观察依那普利在三种不同ACE 基因型中的降压疗效及差异。结果: 在所有68 例原发性高血压患者中, 依那普利治疗前与治疗后每组SBP 和DBP 的降低均有统计学意义(P<0.05), 其中DD 型与Ⅱ型两组之间的SBP 和DBP 降压幅度(即治疗前与治疗后血压的差值)有统计学意义(P<0.05)。DD 型组依那普利的总有效率为91.30 %, ID 型组为85.71 %,Ⅱ型组是79.16 %。结论: 原发性高血压患者中ACE 基因多态性与依那普利降压疗效相关。

Abstract: AIM: To investigate the relationship between the therapeutic effect of enalapril on blood pressure reduction and ACE genetic polymorphisms. METHODS: The genotypes of ACE in 68 patients with essential hypertension were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP)assay.All subjects were randomly divided into three groups (group DD, group Ⅱ, and group ID)according to their different ACE genotypes.68 patients with essential hypertension were treated with 20 mg enalapril daily for 2 consecutive weeks.The changes of systolic and diastolic blood pressure in all subjects were observed before and after enalapril administration.RESULTS: The data showed that there were significantly statistical difference in the systolic blood pressure and diastolic blood pressure in three groups' patients with essential hypertension between before and after enalapril administration (P<0.05).Additionally, there was marked difference in the differential values of systolic blood pressure and diastolic blood pressure reduction between group DD and group Ⅱ(P<0.05).The total efficacy rate of enalapril treatment was 91.30 % in group DD, 85.71 % in group ID, and 79.16 % in groupⅡrespectively, which indicated enalapril had the best effect on blood pressure reduction in DD genotyped group.CONCLUSION: The therapeutic effect of enalapril on blood pressure reduction is associated with ACE genetic polymorphism and the essential hypertensive patients with DD genotypes had the best response to enalapril treatment compared with ID genotypes andⅡgenotypes.

Key words: essential hypertension, gene polymorphism, ACE, enalapril
