Protective effect of Golden Bifid treatment on slow transit constipation rat

The goal of this study is to compare the differently expressed genes in colon tissue of Control and loperamide (LOP) induced slow transit constipation (STC) rat model with or without Golden Bifid (Jin Shuang Qi, JSQ) or positive control group (Prukapril Succinate Tablet, PST) treatment. The loperamide induced STC rat model were randomly divided into 3 groups: LOP, LOP + JSQ and LOP + PST groups (n=6 for each group). Control rats (n=6) were set as control. The STC rat model was induced by administering loperamide intraperitoneally at a dose of 3 mg/kg body weight twice daily for 21 days in all groups except the Control group. On the 8th day, the LOP + JSQ group was intragastrically with 0.540 g/kg/d 1 h after each loperamide administration for 14 days. The LOP + PST group was given prucalopride succinate tablets at a dose of 0.18 mg/kg/d by oral gavage 1 h after each loperamide administration for 14 days. Then the colon tissues were used to identify differentially expressed genes among different groups. Overall design: RNA sequencing was performed with colonic rats in 4 groups: Control, LOP, LOP + JSQ and LOP + PST treated (n=6 for each group) to identify the differently expressed genes and related pathway.
