AIM: To study the effects of Huoxue Huayu and Yiqi Wenyang compound prescription (composition; ginseng, radix astragali, plantaginis semen, lignum sappan, chuanxiong, salvia miltiorrhiza, radix aconiti lateralis preparata, bitter orange, cassia twig) of TCM on the congestive heart failure in rats. METHODS:The rats were given doxorubicin hydrochloride by intraperitoneal injection to establish the model of congestive heart failure and were randomly divided into control group, congestive heart failure model group, Xinbao treatment group ( XB treatment) and Huoxue Huayu and Yiqi Wenyang compound prescription treatment group (QXYTM treatment). Normal saline, liquid medicine Xinbao and liquid medicine Huoxue Huayu and Yiqi Wenyang compound prescription were administered respectively to four groups by gavage. Radioimmunoassay, semi - quantitative RT - PCR and flow cytometry methods were used to determine the expressions of plasma atrial natriuretic peptide ( ANP) , renal medulla aquaporin - 2 ( AQP2 ) and heat shock protein70 (HSP70) in congestive heart failure rats before and after treatment. RESULTS: In congestive heart failure rats treated with Huoxue Huayu and Yiqi Wenyang compound prescription, the cardiac output and left ventricle systolic pressure increased significantly, the left ventricular end diastolic pressure decreased, and the maximum ascending and declining rate of left ventricular pressure ameliorated, thus the hemodynamics was effectively improved. Meanwhile, the level of plasma cardionatrin decreased, the abnormal expression of renal medulla AQP2 was markedly restored, and the transcription and expression of HSP70 gene were also increased. CONCLUSION: Huoxue Huayu and Yiqi Wenyang compound prescription promotes the recovery of the pathogenetic conditions of congestive heart failure in rare. The mechanism may be in association with a decrease in plasma ANP level, correction of renal medulla AQP2 abnormal expression and enhancement of HSP70 expression.%目的:研究补气温阳、活血化瘀中药复方(组成:人参、黄芪、车前子、苏木、川芎、丹参、制附子、枳壳、桂枝)对大鼠充血性心力衰竭的影响机制.方法:以大鼠腹腔注射盐酸阿霉素(ADR)制造充血性心衰动物模型,分为对照组、ADR心力衰竭模型组、心宝治疗组、活血温阳益气复方治疗组,并分别以生理盐水、心宝药液、活血温阳益气复方药液灌胃干预治疗,使用放免法、半定量逆转录-聚合酶链反应法(RT-PCR)及流式细胞技术测定心衰大鼠治疗前后血浆心钠素(ANP)、肾髓质精氨酸血管加压素依赖性水通道蛋白-2(AQP2)及热休克蛋白70(HSP70)的表达水平差异.结果:活血温阳益气复方可显著提高心衰大鼠的心输出量、左室收缩内压,降低左心室舒张末压,改善左室内压最大变化速率,从而有效地改善了心衰大鼠的血流动力学;同时,该方能够显著降低心衰大鼠血浆ANP的水平和纠正心衰大鼠肾髓质AQP2蛋白的异常表达,并可提高白细胞中HSP70的转录和翻译水平.结论:该活血温阳益气复方能有效减轻大鼠充血性心力衰竭的程度,其机制可能与其减少血浆ANP水平、矫正肾脏AQP2异常表达和增强 HSP70表达有关.
