Abstract:
This paper aims to investigate the regulatory mechanism of blood-activating and stasis-dissipating drugs on fecal metabolic characteristics of rhubarb-peach kernel in mice with adenomyosis (AM) using fecal metabolome method. Adenomyosis was modeled by pituitary transplantation, and after the end of modeling administration, fecal samples were collected from mice. Non-targeted metabolomics studies were performed using liquid chromatography-mass spectrometry (LC-MS) to compare the metabolic characteristics of the feces of mice in each group and to find intestinal differential metabolites and potential differential metabolic pathways. The results showed that compared with the normal group, 5-hydroxy-L-tryptophan, histidine, L-acetylcarnitine, 16-hydroxy hexadecanoic acid, thromboxane B2, etc. were significantly up-regulated, L-urobilin and prostaglandin D3 were down-regulated in the feces of the model group, and were reversed after treatment with the rhubarb-peach kernel. The results of metabolic pathway enrichment analysis showed that tryptophan metabolism and histidine metabolism were the main intervention pathways of the rhubarb-peach kernel on AM intestinal metabolism. This study found that the underlying mechanism of the rhubarb-peach kernel in the treatment of AM is related to the intervention of intestinal metabolism of tryptophan, histidine, bile acid, choline and arachidonic acid, and the regulation of pro-inflammatory microenvironment and fatty acid metabolic homeostasis. This study has been approved by the Experimental Animal Ethics Committee of China Three Gorges University (No. 20190801).
