Acute myocardial infarction (AMI) is recognized to be a severe threat to people’s health conditions and life quality. The accumulation of hepatocyte growth factor (HGF) in ischemic myocardium has been observed in both processes of experimental ischemia and reperfusion (I/R) and permanent coronary artery occlusion. The aim of the study was to investigate the effect of HGF on myocardial cell apoptosis, ventricular remodeling and cardiac function after myocardial infarction (MI) in diabetic rats, and to explore whether the effect is mediated by HGF/c-Met signaling pathway. MI significantly increases LVWI and RVWI and myocardial apoptotic index, and up-regulates the expression of HGF and c-Met at mRNA and protein levels in MI control group. The LVWI and RVWI, and myocardial apoptosis were reduced by treatment with HGF, which also increased the myocardial cell viability and the expression of HGF and c-Met. In summary, HGF significantly attenuates myocardial apoptosis and improves cardiac function after AMI in diabetic rats by further enhancing the activation of HGF/c-Met pathway.

Abstract Background: Previous studies reported that hepatocyte growth factor (HGF) could promote angiogenesis and cardiac function after myocardial infarction (MI) in pigs. However, the results of these studies were controversial. To clarify the therapeutic efficacy of local HGF administration after MI, we performed a systematic review and meta-analysis of data from the pig models, which could provide evidence for the feasibility of clinical HGF application.Methods: PubMed, EMBASE, and China National Knowledge Infrastructure were searched for randomized studies that correspond to our subject. The search terms included (hepatocyte growth factor OR HGF) AND (heart failure OR HF OR myocardial infarction OR MI OR AMI OR coronary heart disease OR CHD). The primary endpoint indicators were identified as the left ventricular ejection fraction (LVEF) and capillaries density. Other parameters reflecting cardiac function and ventricular remodeling were analyzed as secondary indicators, including ventricular volume, infarct size, apoptotic index and others.Results: In total, 9 studies were finally included in the meta-analysis. On comparing the cardiac function indexes, the HGF group was found to be better than the control group in regard to LVEF, stroke volume, left ventricular end-systolic volume (LVESV) and left ventricular end-diastolic volume (LVEDV). However, no statistically significant differences were found in heart rate. Furthermore, HGF treatment promotes angiogenesis in ischemic areas, which is manifested by increased capillary density. In addition, the HGF group was found to be better than the control group when it comes to infarct size, arteriole densities, and other indicators of cardiac remodeling.Conclusions: HGF treatment can effectively promote cardiac function and cardiac repair including angiogenesis, and this strategy is a promising cardio-protective approach that merits further clinical studies.

Background. Transforming growth factor-beta (TGF-β) and hepatocyte growth factor (HGF) are inflammatory cytokines which function as key regulators of immunological homeostasis and inflammatory responses. They have been linked to inflammatory bowel diseases (IBD). In this study, we aim to assess the levels of TGF-β and HGF and other inflammatory markers in patients with IBD and correlate them with the disease activity. Study Design. A cross-sectional study involving 100 patients with ulcerative colitis (UC) and 100 patients with Crohn’s disease (CD) and 50 control subjects. TGF-β and HGF levels were measured and correlated with disease activity. Results and Conclusion. Serum levels of TGF-β and HGF were significantly higher in IBD patients compared with the control group. In the UC group, the levels of HGF and TGF-β were significantly higher than in the CD group. Levels of TGF-β and HGF correlate with the activity of IBD.

Myocardial Apoptosis

Aim. To determine the effect of a Chinese herbal compound named Wenxin Granule on ventricular remodeling and myocardial apoptosis in rats with myocardial infarction (MI).Methods. Male Sprague-Dawley (SD) rats were randomly divided into four groups: the control group, the model group, the metoprolol group, and the Wenxin Granule group (WXKL group) with sample size (n) of 7 rats in each group. An MI model was established in all rats by occlusion of the left anterior descending coronary artery (the control group was without occlusion). Wenxin Granule (1.35 g/kg/day), metoprolol (12 mg/kg/day), and distilled water (5 mL/kg/day for the control and model groups) were administered orally for 4 weeks. Ultrasonic echocardiography was used to examine cardiac structural and functional parameters. Myocardial histopathological changes were observed using haematoxylin and eosin (H&E) dyeing. Myocardial apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) staining. Serum angiotensin II (Ang II) concentration was measured using the enzyme-linked immunosorbent assay (ELISA).Results. It was found that Wenxin Granule could partially reverse ventricular remodeling, improve heart function, alleviate the histopathological damage, inhibit myocardial apoptosis, and reduce Ang II concentration in rats with MI.Conclusions. The results of the current study suggest that Wenxin Granule may be a potential alternative and complementary medicine for the treatment of MI.
