Research progress on the molecular mechanism of electroacupuncture at "Zusanli" (ST36) for regulating gastrointestinal dysfunction.

Abstract

Gastrointestinal dysfunction is manifested as digestive symptoms. Clinically, Zusanli (ST36) is crucial in the acupoint prescriptions of acupuncture no matter which type of the disease is differentiated in traditional Chinese medicine, but the underlying mechanism remains to be explored. Aiming to summarize the current status of the researches in terms of ameliorating gastrointestinal mucosal damage and regulating gastrointestinal motility disorders, we systematically reviewed the basic researches on the intervention with electroacupuncture (EA) at "ST36" in treatment of the diseases related to gastrointestinal dysfunction in the past 5 years, after searching the articles from Chinese and English databases. The results suggest that EA at ST36 may regulate the local gastrointestinal inflammation, oxidative stress and immune microenvironment to relieve gastrointestinal mucosal damage and adjust gastrointestinal motility disorders by means of modulating the central and peripheral nerve signaling as well as the function of mast cells and Cajal interstitial cells.
