脑-肠轴失调在肠易激综合征发病中作用的研究进展

摘要

肠易激综合征（ IBS）的发生是多因素共同作用的结果，其发病机制尚未明确。近年来，以脑-肠轴为基础的生物-心理-社会医学模式参与IBS发病的观念被广泛接受。由神经-内分泌-免疫网络介导的脑-肠双向调节通路，在维持中枢神经系统与肠道局部稳态中发挥重要调节作用，其中任一环节异常，都可能导致稳态平衡破坏而诱发IBS。本文就脑-肠轴失调在IBS发生、发展中作用的研究进展作一综述。%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.
