Objective To observe the therapeutic effects of Liuwei Shunji Capsule on survival state, visceral hypersensitivity, the content of 5-HT of model rats with liver depression and spleen deficiency-type irritable bowel syndrome (IBS), and explore its mechanism.Methods SD rats were randomly divided into normal group, model group, pinaverium bromide group and Liuwei Shunji Capsule of high, medium and low dose groups. Senna with restraint stress was used in duplicating liver depression and spleen deficiency-type IBS model. From the second day after the model was established, each drug treatment group was administered with corresponding drugs once a day for two weeks. The effects of Liuwei Shunji Capsule on survival state, visceral hypersensitivity, the content of 5-HT in serum and hypothalamus were observed.Results Compared with model group, Liuwei Shunji Capsule could raise weight growth rate of model rats with liver depression and spleen deficiency-type IBS (P<0.05), improve their diarrhea, fatigue demeanor, fur quality, irritability and other symptoms, significantly decrease their visceral hypersensitivity, the content of 5-HT in serum and hypothalamus (P<0.01).Conclusion Liuwei Shunji Capsule can effectively improve survival state and intestinal disorders of rats with liver depression and spleen deficiency-type IBS, and the mechanism of treatment could be realized through regulating 5-HT level.
