Advances in Study on Brain-gut Axis Dysfunction in Pathogenesis of Irritable Bowel Syndrome / 胃肠病学

IrritabIe boweI syndrome( IBS)is caused by muItipIe factors,and the pathogenesis has not yet been cIarified. RecentIy,the roIe of brain-gut axis based bio-psycho-sociaI medicaI modeI in the pathogenesis of IBS has been wideIy accepted. Brain-gut axis forms a nerve-endocrine-immune network mediating bidirectionaI reguIation pathway,which pIays an important roIe in maintaining homeostasis between centraI nervous system and gut. Brain-gut axis abnormaIities may Iead to imbaIance of the homeostasis and subsequentIy induce the occurrence of IBS. This articIe reviewed the advances in study on brain-gut axis dysfunction in pathogenesis of IBS.
