痛泻要方对D-IBS结肠黏膜5-HT及CGA相关离子通道转运机制的研究

摘要

腹泻型肠易激综合征( diarrhea-predominant irritable bowel syndrome,D-IBS)是临床常见的功能性肠道疾病,给患者的生活和工作带来诸多不便。痛泻要方作为中医古代著名方剂,能够明显减轻D-IBS患者的腹痛、腹泻症状,提高其生活和工作质量,但其治疗的确切机制尚不明确,本文从5-羟色胺及嗜铬素A( chromogranin A,CGA)相关离子通道转运机制的角度出发,探讨痛泻要方对D-IBS结肠黏膜离子通道的影响,以期为后续的临床与基础研究提供可靠的依据。%Diarrhea-predominant irritable bowel syndrome( D-IBS) is a clinically common functional intestinal disease and it brings inconvenience to patientsˊ live and work. TongXie-YaoFang(TXYF) formula, as a famous ancient prescription of Traditional Chinese Medicine, can significantly reduce the abdominal pain and diarrhea of D-IBS patients, thereby to improve the quality of their live and work. However, the exact mechanism is unclear. This article explores the influence of TXYF formula on ion channels of colon mucous membrane in D-IBS from the perspective of 5-HT and chromogranin A( CGA) related ion channel transport mechanism in order to provide reliable basis for subsequent clinical and basic research.
