Abstract:
Objective By investigating the effects of AT1 and ERK2 signaling pathway in CHF,to study the effect of Guanxin-Shutong capsule on AT1,ERK2 expression in rats with chronic heart failure (CHF).Methods The CHF rat models were setup by coronary artery ligation,exhausting swimming and reducing feeding.Divided CHF rat methods into a model group,a lisinopril group,Qi-benefiting with Chinese medicine group,blood activating with Chinese medicine group,Qi benefiting and blood activating with Chinese medicine group(QBBA group) and Guanxin-Shutong capsule group.Rats without left coronary artery ligation were set for sham operated group.Real-time quantitative PCR technique and immunohistochemical method were adopted to detect AT1,ERK2 changes of CHF rats.Results AT1,ERK2 expression increased obviously in the model group compared with the sham operated group,and differences were statistically significant (P＜0.01).After treatment,AT1,ERK2 expression reduced significantly in QBBA group and Guanxin-Shutong capsule group than the lisinopril group.(P＞0.05).And therapeutic effect of Guanxin-Shutong capsule group was much better than other Chinese medicine treated group (P＜0.01).Conclusion Guanxin-Shutong capsule would achieve the goal of treating chronic heart failure By inhibiting the expression of AT1 and ERK2 in organizations,and inhibiting or reversing ventricular remodeling process.
