Influence of Tiaogan Yunpi Decoction on the Regional Encephalic Activation of MR Signal Variation among Diarrhea Type Irritable Bowel Syndrome Patients / 中国中医药信息杂志

Objective To investigate the Tiaogan Yunpi Decoction on the region of interest regional encephalic activation MR signal intensity variation among diarrhea type irritable bowel syndrome(IBS) patients.Method Adopting self-paired collated method,functional fMRI was used to observe the regional interest MR signal variation of anterior cingulate cortex(ACC),island cortex(IC),prefrontal cortex(PFC),hypothalamus(THAL) before and after the treatment,as well as after the controlled treatment using placebo among 18 diarrhea dominant IBS patients when they were rectum stimulated.Results After the treatment,when the injected gas reached 90 mL,the change of MR signal variation of IC was signifycantly decreased compared with that before the treatment(P
