摘要：

Context: Traditional Chinese medicine plays an important role in the prevention and treatment of heart failure (HF). Linggui Zhugan decoction has been approved for clinical treatment of chronic HF. However, the mechanism is still unclear. Objective: The effect of Linggui Zhugan decoction on the Wnt/beta-catenin signaling pathway in rat myocardium was studied to investigate the mechanism by Linggui Zhugan decoction effects ventricular remodeling in rats with heart failure after myocardial infarction. Method: A rat model of HF after myocardial infarction was prepared by ligating the left anterior descending coronary artery. After 6 weeks of intervention with Linggui Zhugan decoction, the effect of Linggui Zhugan decoction on the cardiac function of chronic HF model rats was observed. Myocardial infarct size was measured by triphenyl tetrazolium chloride (TTC) staining. Enzyme linked immunosorbent assays (ELISAs) were used to measure NT-proBNP and sST-2 concentrations in rat serum. Hematoxylin and eosin (H&E) staining, and Masson's trichrome staining were used to observe the morphology of myocardial tissue; immunohistochemistry was used to detect the protein expression of type I collagen and type III collagen in myocardial tissue; and mRNA expression levels of Wnt3a, GSK-3 beta, beta-catenin, and c-Myc in the infarct marginal zone were detected using PCR. Protein expression of Wnt3a, p-GSK-3 beta, GSK-3 beta, and beta-catenin in the infarct marginal zone was detected using western blot. Results: Compared with the control, Linggui Zhugan decoction reduced the levels of serum ST-2 and NT-proBNP, improved cardiac function, and reduced the deposition of collagen fiber. In addition, Linggui Zhugan decoction inhibited the expression of Wnt3a, p-GSK-3 beta, and beta-catenin in cardiomyocytes. Conclusion: Linggui Zhugan decoction inhibits the expression of several key proteins in the Wnt/beta-catenin signaling pathway, delays cardiomyocyte hypertrophy and fibrosis, and improves cardiac function.
