Abstract | OBJECTIVE: To establish a new disease-syndrome-symptom integrated diarrhea-predominant irritable bowel syndrome (IBS-D) rat model of Gan stagnation and Pi deficiency syndrome (GSPDS). METHODS: (1) The model establishment method: We combined mother-infant separation, chronic restraint, and senna gavage to establish a new IBS-D model of GSPDS. Totally 48 experimental rats were divided into the normal group (Group A), the mother-infant separation group (Group B), the chronic restraint group (Group C), and the senna gavage group (Group D), the mother-infant separation + senna gavage group (Group E), and the mother-infant separation + chronic restraint + senna gavage group (Group F), 8 in each group. (2) The model evaluation method: We used pain threshold indicating colorectal distension to represent for the visceral sensitivity, thus evaluating the establishment of "disease" model; open field test and serum D-xylose levels to evaluate the establishment of GSPDS model; defecation numbers of grain and loose stool rate to evaluate the establishment of diarrhea symptom. RESULTS: (1) Compared with Group A, the body weight gained less in Group F, showing statistical difference (P < 0.05). (2) The pain threshold significantly decreased in Group F, showing statistical difference when compared with Group A (P < 0.05). (3) Compared with Group A, the total cross number, the standing number, and the decoration number in Group F significantly decreased (P < 0.05). (4) Compared with Group A, the serum D-xylose level of Group F significantly decreased (P < 0.05). (5) Compared with Group A, the defecation numbers of grain and the loose stool rate significantly increased, showing statistical difference (P < 0.05). CONCLUSIONS: A new disease-syndrome-symptom integrated IBS-D animal model of GSPDS successfully established might be a better animal model used for studying IBS by Chinese medicine. However, further studies are needed.
