This study was aimed to explore the clinical efficiency of modified Xiao-Yao (XY) powder and acupuncture in the treatment of diarrhea -predominant irritable bowel syndrome (D -IBS). A total of 90 D-IBS patients were randomly divided into the treatment group and control group, with 45 patients in each group. Patients in the treatment group received acupuncture combined with modified XY powder. Patients in the control group received oral administration of montmorillonite powder, compound glutamine enteric -coated capsules, compound azintamide enteric coated tablet. Four weeks were one treatment course. After two treatment courses, the pretreatment and posttreatment symptom score, the score of Hamilton Depression Rating Scale (HAMD)/(HAMA), and the overall efficacy were compared. The results showed that compared with pretreatment, clinical symptoms were improved in varying degrees after treatment in both groups (P < 0.05 or P < 0.01). HAMD and HAMA were significantly decreased (P < 0.05). The treatment group had obvious advantages compared to the control group (P < 0.05). The overall efficacy of the treatment group was 91.11%, which was significantly higher than the control group of 68.89% (P < 0.05). It was concluded that modified XY powder and acupuncture can quickly relieve gastrointestinal symptoms, improve anxiety and depression. It is an effective treatment method for D-IBS.
