The effect of the yang-warming and fluid retention-resolving method on AngⅡ, TNF-α and IL-6 expression in rats with chronic heart failure / 国际中医中药杂志

ABSTRACT

Objective To observe the effect of the yang-warming and fluid retention-resolving mothed on neuroendocrine and inflammatory factors in chronic heart failure (CHF) rats. Methods A total of 50 healthy adult male SD rats were randomly divided into blank group (10), CHF group (40). In CHF group, the rat model of chronic heart failure was replicated by intraperitoneal injection of adriamycin (ADR). After the completion of the model making, doppler echocardiography was used to determine the cardiac function of rats. There rats were randomly divided into the model group, the yang-warming and fluid retention-resolving group, the Xuefu-Zhuyu group and the captopril group. After continuous administration for 28 d and 2 h after the last dose, the HE staining was used to observe the pathological morphological changes of myocardium in each group. The levels of AngⅡ, TNF-α and IL-6 in serum were by ELISA. Results Compared with model group, the content of serum AngⅡ(294.33 ± 25.45 pg/ml, 265.86 ± 27.80 pg/ml, 301.87 ± 41.67 pg/ml vs. 615.44 ± 22.31 pg/ml), TNF-α(117.15 ± 11.33 pg/ml, 114.02 ± 11.57 pg/ml, 133.35 ± 34.80 pg/ml vs. 185.72 ± 36.53 pg/ml), IL-6 (23.97 ± 4.77 pg/ml, 27.61 ± 7.01 pg/ml, 28.38 ± 5.78 pg/ml vs. 58.45 ± 6.36 pg/ml) in the yang-warming and fluid retention-resolving group, Xuefu-Zhuyu group and captopril group significantly decreased (P<0.01 or P<0.05). Compared with Xuefu-Zhuyu group, the content of serumAngⅡ (301.87 ± 41.67 pg/ml vs. 265.86 ± 27.80 pg/ml) in the captopril group significantly increased (P<0.05). Conclusions The yang-warming and fluid retention-resolving mothed can reduce early CHF rats through reducing the serum TNF-α, Ang and ILⅡ -6 content, which could be one of the mechanism of action of the treatment of CHF.
