ObjectiveTo explore gut microbiome influences on anastomotic healing following gastrointestinal surgery and its mechanism.MethodThe relevant literatures about gut microbiome and its impact on healing of gastrointestinal anastomosis and their mechanisms were reviewed.ResultsSeveral symbiotic intestinal microbiota such as the Enterococcus faecalis, Pseudomonas aeruginosa, Serratia marcescens, etc. could transform into the pathogenic bacteria with high toxic phenotype in an inflammatory environment in the body, and dissolve the extracellular matrix by degrading collagen or activating matrix metalloproteinase 9, resulting in the anastomotic leak.ConclusionIn general, exploring of effect of intestinal microbiome on healing process of anastomotic stoma is just beginning, conditions and mechanisms for transformation of bacteria from symbiotic to pathogenic still need to be explored.
End-stage renal disease is a late complication of chronic kidney disease (CKD) and one of the leading causes of high mortality worldwide. Over the years, the impacts of gut microbiota and their associated uremic toxins on kidney diseases through the intricate “gut-kidney axis” have been extensively studied. However, translation of microbiome-related omics results into specific mechanisms is still a significant challenge. In this paper, we review the interaction between gut microbiome and blood purification, as well as the current microbiota-based therapies in CKD. Additionally, the current sequencing technologies and progresses in the gut microbiome research are also discussed.
