摘 要:BACKGROUND Slow transit constipation(STC)is a common intestinal disease with increasing incidence.STC results from various factors,such as the enteric nervous system and metabolic changes.As a classical formula of traditional Chinese medicine,Ji-Chuan decoction(JCD)has been extensively and effectively used in STC treatment,yet its pharmacological mechanism remains unclear.AIM To explore the integrated regulatory pattern of JCD against STC through hyphenated techniques from metabolism,network pharmacology and molecular methods.METHODS STC model mice were generated by intragastric administration of compound diphenoxylate(10 mg/kg/d)for 14 d.The STC mice in the low dose of JCD(3.04 g/kg),middle dose of JCD(6.08 g/kg)and high dose of JCD(12.16 g/kg)groups were orally administered JCD solution once a day for 2 wk.The acetylcholine(ACH)level was examined by enzyme-linked immunosorbent assay.The pathological features of colon tissue were observed by hematoxylin and eosin staining.The differentially expressed metabolites and metabolic pathways were tested by nontargeted metabolomics.The main targets and core ingredients of JCD were identified by network pharmacology,and the expression of AKT was confirmed by immunohistochemistry.Finally,the pathways involved in JCD treatment were predicted using a combination of differentially expressed metabolites and targets,and intestinal glial cell apoptosis was demonstrated by immunofluorescence.RESULTS JCD significantly promoted intestinal motility,increased the levels of the excitatory neurotransmitter ACH and reduced intestinal inflammation in STC mice.Untargeted metabolomics results showed that JCD significantly restored metabolic dysfunction and significantly affected taurine and hypotaurine metabolism.Network pharmacology and molecular experiments showed that JCD regulates AKT protein expression,and the core component is quercetin.Combined analysis demonstrated that apoptosis may be an important mechanism by which JCD relieves constipation.Further experiments showed that JCD r
