Abstract:
ObjectiveBased on ultra performance liquid chromatography-mass spectrometry（UPLC-MS） and non-targeted metabolomics technology to discuss the central regulatory effect of Chaishao Liujuntang on chronic atrophic gastritis（CAG） rats with liver-depression and spleen-deficiency， and to look for the correlation between cerebral cortex， hypothalamus and metabolic status of gastric tissues. MethodA CAG rat model with liver-depression and spleen-deficiency was established by chemical induction， hunger and satiety disorders， chronic restraint and tail clamping stimulation， lasting for 16 weeks. Twenty-eight Wistar rats were randomly divided into a blank group of 8 rats and a model group of 20 rats. After the completion of modeling， 4 rats in the model group were taken to observe the pathological changes of gastric mucosa. The remaining model rats were randomly divided into a model group of 8 rats and a Chaishao Liujuntang group of 8 rats. Chaishao Liujuntang group rats were given 5.1 g·kg-1 by gavage， and the remaining rats were given equal volume sterilized water by gavage for 4 weeks. Macroscopic characteristics， behavioral indicators and histopathological changes of the gastric mucosa of rats in each group were observed and compared. UPLC-MS non-targeted metabolomics was used to explore the metabolic regulation effect of Chaishao Liujuntang on the cerebral cortex， hypothalamus and stomach tissues of CAG rats with liver-depression and spleen-deficiency. Pearson correlation coefficient method was used to analyze the correlation between different tissue metabolites. ResultCompared with the model group， the macroscopic characteristics of rats in Chaishao Liujuntang group were improved， such as hair color， mental state and stool properties， and the number of times of crossing and standing in the open field experiment was significantly increased， and the static time of forced swimming was significantly reduced（P<0.01）， and the gastric mucosa atrophy was reduced. The metabolic data from the cerebral cortex of rats in each group identified a total of 3 common potential biomarkers， but not enriched in pathways， 26 common potential biomarkers were identified in the hypothalamus， and the key metabolic pathways involved were mainly enriched in purine metabolism， glycerol phospholipid metabolism， D-glutamine and D-glutamic acid metabolism. Seventeen common potential biomarkers were identified in the stomach， and the key metabolic pathways involved were mainly enriched in thiamine metabolism， valine， leucine and isoleucine biosynthesis， and taurine and taurine metabolism. Correlation analysis of metabolites in different tissues revealed that multiple amino acids and their derivatives mediated metabolic connections between the cerebral cortex， hypothalamus and stomach of rats. ConclusionThe metabolic disorders in the cerebral cortex， hypothalamus and stomach of CAG rats with liver-depression and spleen-deficiency have their own characteristics， mainly manifested by changes in the content of glycerol phospholipids， fatty acids and bile acid metabolites. Moreover， Chaishao Liujuntang may play a central regulatory role in CAG rats with liver-depression and spleen-deficiency by correcting the metabolic disorders of amino acids.
