description | BACKGROUND: Gastric ulcer is a common chronic disease in human digestive system, which is difficult to cure, easy to relapse, and endangers human health seriously. Compared with western medicine, traditional Chinese medicine has a unique advantage in improving the general situation, stablizing medical condition, and with little side effects. Glycyrrhiza known as “king of all the medicine”, has a range of pharmacological activities and is commonly used in a variety of proprietary Chinese medicines and formulations. OBJECTIVE: On the basis of explicit antiulcer effect of Glycyrrhiza triterpenes, the molecular mechanisms of its therapeutic effect on acetic acid induced gastric ulcer in rats were explored. MATERIALS AND METHODS: Acetic acid induced gastric ulcer model in rats was established to evaluate the curing effect of G. triterpenes and all of the rats were randomised into six groups: Control group, model group, omeprazole group (0.8 mg/mL), triterpenes high dose group (378.0 mg/mL), triterpenes middle dose group (126.0 mg/mL), and triterpenes low dose group (42.0 mg/mL). All rats in groups were orally administered the active group solution 1.5 mL once daily (model and control groups with saline) for 7 days. HPLC-TOF-MS analysis method was performed to obtain the plasma metabolites spectrums of control group, model group, triterpenes high, middle and low dose groups. RESULTS: A total of 11 differential endogenous metabolites related to the therapeutic effect of G. triterpenes were identified, including tryptophan, phingosine-1-phosphate, pantothenic acid, and so on, among which tryptophan and phingosine-1-phosphate are related with the calcium signaling pathway and arachidonic acid (AA) metabolism. At the same time, in order to verify the above results, quantitative real time polymerase chain reaction were performed to evaluate the expression of H(+)-K(+)-ATPase alpha mRNA and phospholipase a 2 mRNA in relational signaling pathways. Combined with statistical analysis of plasma metabolic spectrum and gene expression in tissue, it is suggested that G. triterpenes has antiulcer effect on gastric ulcer in rats. CONCLUSION: G. triterpenes has a certain regulating effect on the metabolism of tryptophan, AA, sphingosine, and other endogenous metabolites, and we speculated that the antiulcer potential of G. triterpenes can be primarily attributed to its inhibiting gastric acid secretion, reducing the release of inflammatory mediators, and protecting gastric mucosa effects to prevent the further development of gastric ulcer. SUMMARY: G. triterpenes can obviously relieve the symptoms of gastric ulcer, especially the low dose group. G. triterpenes can effectively regulate the amount of small molecule metablism in gastric ulcer rats in vivo, including tryptophan, phingosine-1-phosphate, etc. G. triterpenes resisting gastric ulcer is probably by regulating arachidonic acid metabolism, sphingosine metabolism, etc. Down-regulation of H+-K+-ATPase alpha subunit mRNA and up-regulation of PLA(2) mRNA in gastric tissue of dose group validated the possible mechanisms of G. triterpenes for the treatment of gastric ulcer.
