Abstract:
OBJECTIVE To explore the mechanism of Kuaisong yin in the prevention and treatment of constipation. METHODS Slow transit constipation （STC） model was established with Compound difenoxylate tablet in mice and rats. Two batches of mice were divided into blank group， model group， positive control group （Maren soft capsule， 0.64 g/kg）， Kuaisong yin low-dose， medium-dose and high-dose groups （3.2， 6.4， 12.8 g/kg）， with 10 mice in each group. The effect of Kuaisong yin on constipation in mice was evaluated by intestinal propulsion experiment and defecation experiment. Rats were divided into blank group， model group， positive control group （Maren soft capsule，0.36 g/kg）， Kuaisong yin low-dose and high-dose groups （2.4， 4.8 g/kg）， with 7 or 8 rats in each group. They were given relevant medicine once a day for 1 week. The metabonomics of serum and urine of rats were analyzed by UPLC-Q-TOF-MS/MS technology. RESULTS Compared with model group， the ink propulsion rate and 5 h defecation volume of mice in Kuaisong yin high-dose group were significantly increased （P＜0.05）； the first defecation time of mice in Kuaisong yin medium-dose and high-dose groups was significantly shortened， and the quality of defecation was significantly reduced within 5 h （P＜0.05 or P＜0.01）. Serum metabonomics screened 16 compounds （such as proline， propionylcarnitine， hemolytic phosphatidylcholine， etc.） and 6 metabolic pathways （such as sphingomyelin metabolism， arginine and proline metabolism， sphingolipid biosynthesis-lactose and neolactone series）. Urine metabonomics screened 20 different metabolites （such as prostaglandin A2， L-valine， phosphatidylcholine， sphingomyelin， etc.） and 8 metabolic pathways （such as valine， leucine and isoleucine biosynthesis， sphingomyelin metabolism， pyruvate metabolism， etc.）. CONCLUSIONS Kuaisong yin can play a role in improving constipation by regulating different metabolites such as hemolytic phosphatidylcholine， phosphatidylcholine， prostaglandin A2， L-valine， proline， and regulating metabolic pathways such as multiple amino acid metabolism， sphingomyelin metabolism， etc.
