ABSTRACT
AIM: To observe the clinical efficacy of Fuzheng Xiaoliu Granules in the treatment of stage II primary liver cancer and to explore its mechanism of action from the perspective of metabolomics. METHODS: Sixty patients with stage II primary liver cancer who achieved complete remission (CR) after comprehensive interventional therapy were randomly divided into treatment group and placebo group, with 30 patients in each group. They were treated for one year and observed for one year. The one-year recurrence rate, traditional chinese medicine (TCM) syndrome score, alpha-fetoprotein and child-pugh grade were compared between the two groups. The serum metabolites of the two groups before and after treatment were screened by ultra-high liquid chromatography-mass spectrometry technology, and the metabolic pathways and related biological pathways were analyzed. RESULTS: The one-year recurrence rate of the treatment group was significantly lower than that of the placebo group, and the overall improvement rate of TCM syndrome score was significantly better than that of the placebo group (P0.05). Metabolomics results showed that there were 39 and 33 different metabolites in the treatment group before and after treatment and in the two groups after treatment, respectively. After enrichment analysis and topological analysis of the different metabolites, it was found that Fuzheng Xiaoliu Granules could affect amino acid metabolism, fatty acid metabolism and purine metabolism and other metabolic pathways. Before and after treatment in the treatment group and after treatment in the two groups, there were the same differential metabolites and metabolic pathways in the two comparison results. The same differential metabolites with FOLD CHANGE>1 include Stearic acid, Hypoxanthine, Kynurenic acid, Arachidonic acid, and N-Arachidonoyl Dopamine. The same metabolic pathways with Impact>0.1 include Arachidonic acid metabolism and Histidine metabolism. CONCLUSION: Fuzheng xiaoliu granules can effectively reduce the recurrence rate of stage II liver cancer patients after comprehensive intervention and improve the TCM syndrome. It may inhibit the activation of PI3K/Akt and ERK signaling pathways by regulating the content of metabolites involved in metabolic pathways such as amino acids and fatty acids, thereby delaying tumor recurrence.
ABSTRACT
There is still a lack of effective strategies for the prevention and treatment of liver cancer, and a deep understanding of its pathogenesis may help to develop new treatment methods. Due to the abnormal changes of lipid metabolism in the development and progression of liver cancer, such process is closely associated with the "phlegm-turbidity" theory in traditional Chinese medicine (TCM). Starting from the changes of lipid metabolism in hepatocellular carcinoma microenvironment, this article discusses the association of the abnormal changes of lipid metabolism in tumor cells and immune cells with the "phlegm-turbidity" theory and the clinical efficacy of phlegm-eliminating therapies in clinical practice. Since the "phlegm-turbidity" theory in TCM plays an important role in the pathogenesis and pathological changes of liver cancer, the analysis of its theoretical connotation helps to clarify pathological mechanism, thereby providing a theoretical basis for the role of TCM in the prevention and treatment of liver cancer.
