Preprints with The Lancet is part of SSRN´s First Look, a place where journals and other research experts identify content of interest prior to publication. These preprint papers are not peer-reviewed and are posted here as part of a 12-month trial. Authors have either opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet, or submitted directly via SSRN. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. These papers should not be used for clinical decision making or reporting of research to a lay audience without indicating that this is preliminary research that has not been peer-reviewed.

Abstract

Background: Adult mammalian heart repair after myocardial damage is highly inefficient due to the post-mitotic nature of cardiomyocytes. Interestingly, in Traditional Chinese Medicine (TCM), there are reported effective treatments of myocardial infarction and heart failure in adult humans by oral intake of a TCM concoction named Gu Ben Pei Yuan San (GBPYS) .  

Methods: We fed the mice with GBPYS after myocardial damages through everyday self-feeding. We then examined the effect of everyday oral intake of GBPYS on improving cardiac function and myocardial repair in adult mice after apical resection or myocardial infarction.  

Findings: We found that long-term oral intake of GBPYS significantly improved cardiac function after myocardial damages in adult mice. Brdu, Phospho-histone 3, and AuroraB staining indicated increased cell proliferation at the border zone of MI after TCM feeding. GBPYS feeding reduced organ inflammation and is nontoxic to mice after long-term oral intake. Further, serum derived from TCM fed MI rats promoted division of both neonatal rat cardiomyocytes and human iPSC-derived cardiomyocytes in vitro.

Interpretation: Oral intake of GBPYS improved heart repair after myocardial damages in adult mice. Our results suggest that there are substances present in GBPYS that help improve adult mammalian heart repair after MI.
