Chaihulonggumulitang Shows Psycho-cardiology Therapeutic Effects on Acute Myocardial Infarction by Enhancing Bone Marrow Mesenchymal Stem Cells Mobilization

Ischemic myocardium initiates the mobilization and homing of bone marrow mesenchymal stem cells (BM-MSCs) to promote myocardial regeneration after acute myocardial infarction (AMI). Inflammation caused by necrotic cardiomyocytes induce major pathological changes (cardiac remodeling and myocardial apoptosis) as well as anxiety disorder. This process may be inhibited by the differentiation and paracrine effects of BM-MSCs. However, the spontaneous mobilization of BMSCs is insufficient to prevent this effect. Given the anti-inflammatory effects of BM-MSCs, ventricular remodeling and anxiety following AMI, methods focused on enhancing BMSCs mobilization are promising. BFG is a classical traditional Chinese prescription medicine and has been proved effective in treating AMI and reducing anxiety, but the potential mechanism of its function remains unknown. In the present study, we explored the effects of Chaihulonggumulitang (BFG) on AMI and anxiety in vivo and in vitro. We also tested its effects in promoting BMSCs mobilization and alleviating inflammation. Our data showed that the classical Chinese prescription BFG promoted BM-MSCs mobilization, inhibited inflammatory response, and improved heart damage and anxiety developed from AMI. Thus, we provided an underlying mechanism of BFG function in psycho-cardiology conditions such as AMI.
