Summary:Primary liver cancer is the third most common malignancy, and hepatocellular carcinoma is its main subtype, with a high recurrence rate and high mortality. Intestinal microflora and metabolic disorders are present in most HCC patients. Traditional Chinese medicine (TCM) plays an important role in the composition of intestinal microorganisms and the transformation of active metabolites. Many scholars are trying to develop related drugs to assist in the treatment of liver cancer. In the preliminary study of the research group, it was found that the Jiawei Xiaoyao San has a certain therapeutic effect on liver cancer, but the specific mechanism is still unclear. Therefore, this study constructed a liver cancer rat model with liver stagnation and spleen deficiency, to explore the regulatory effect of Jiawei Xiaoyao San on plasma metabolites and intestinal microflora and to find the potential mechanism of Jiawei Xiaoyao San in the treatment of liver cancer. Plasma samples and fecal samples were collected from liver cancer rats with liver depression and spleen deficiency for microbiome 16S rDNA sequencing and metabolic ESI-QTRAP-MS/MS analysis. Various bioinformatics methods were used to analyze the dataset individually and in combination. The analysis and identification of plasma metabolomics showed that the intervention effect of Jiawei Xiaoyao San on liver cancer rats with liver depression and spleen deficiency was related to 11 differential metabolites and signal pathways such as primary bile acid biosynthesis, phenylalanine metabolism, pantothenate and COA biosynthesis, metabolic pathways, cholesterol metabolism, and bile secretion. Combined with fecal microbiological analysis, it was found that Jiawei Xiaoyao San could significantly change the composition of intestinal flora in liver cancer rates, increase beneficial bacteria, and reduce the composition of harmful bacteria. This study provides some experimental basis for the traditional Chinese medicine theory and clinical application of Jiawei Xiaoyao San in the adjuvant treatment of liver cancer. The potential mechanism may be to regulate metabolism and intestinal flora to play the role of regulating liver depression, activating blood, and detoxifying, to achieve the purpose of adjuvant treatment of liver cancer.
