Effects of Huoxue Huayu and Yiqi Wenyang compound prescription of TCM on congestive heart failure in rats / 中国病理生理杂志

ABSTRACT

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.
