非洛地平对高血压患者血浆生长素水平和血管内皮功能的影响

目的:研究非洛地平对原发性高血压患者血浆生长素水平和血管内皮功能的影响。方法:原发性高血压患者77例,随机分为治疗组(45例)与对照组(32例),治疗组在对照组限盐、低钠饮食、适当锻炼、减轻体重、口服利尿药治疗的基础上加服非洛地平5mg,1次.d-1,治疗8wk。观察血浆生长素水平(Ghrelin)、肱动脉血流依赖性舒张功能(FMD)、一氧化氮(NO)、内皮素-1(ET-1)治疗前后变化。结果:治疗组治疗前后比较,血浆Ghrelin水平、NO、FMD明显升高,差异有统计学意义(P<0.01或P<0.05);ET-1水平降低,差异有统计学意义(P<0.01)。对照组治疗前后比较,以上指标变化无统计学意义(P>0.05)。结论:非洛地平降压治疗同时可提高血浆生长素水平,改善高血压患者的血管内皮功能。

Effects of Felodipine on Plasma Ghrelin Level and Endothelial Function of Blood Vessels in Patients with Essential Hypertension

OBJECTIVE:To observe the effects of gelodipine on plasma ghrelin level and endothelial function of blood vessels in patients with essential hypertension.METHODS:A total of 77 patients with essential hypertension were randomly divided into trial group(n=45)and control group (n=32).Both groups were given low sodium diet,proper exercise, weight reduction and oral diuretics,while the trial group was assigned to receive felodipine 5mg q.d additionally.The course of treatment was 8wk.Before and after the treatment,plasma levels of ghrelin and nitrous oxide(NO),endothelin(ET-1),and brachial artery flow-mediated dilatation(FMD)function were observed.RESULTS:Plasma levels of ghrelin and NO,and FMD were significantly increased (P<0.01 or P<0.05)but ET-1 were significantly decreased(P<0.01)in felodipine group after treatment as compared with before treatment.However,in the control group,the above indexes showed no significances after treatment as compared with before treatment(P>0.05).CONCLUSION:Felodipine can increase plasma Ghrelin level meanwhile improving endothelial function of blood vessels in patients with essential hypertension.
