ObjectiveTo investigate the mechanism of action of Xiaoyao powder combined with Sijunzi decoction, Artemisia capillaris Thunb. decoction, Longdan Xiegan decoction combined with Xiayuxue decoction, Wupi decoction combined with Sijunzi decoction, and Yiguan decoction in the treatment of hepatocellular carcinoma (HCC) based on network pharmacology and molecular docking. MethodsDatabases including TCMSP, TCMID, BATMAN-TCM, and TCM-MESH were used to screen out effective components and predict their targets, and databases including TTD, Drugbank, Disgenet, Liverome, OncoDB.HCC, and GEO were used to investigate HCC-related targets. The drug and disease targets were mapped to obtain the intersecting targets, and the visualization software Cytoscape 3.7.1 was used to construct the core component-intersecting target network and the protein-protein interaction (PPI) network. The core components and key genes were screened out and a survival analysis was performed in the GEPIA database. The active components and key genes screened out were imported into the DockThor online website for molecular docking. In addition, David database was used to perform gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the intersecting targets. ResultsThe analysis showed that 110, 19, 154, 121, and 51 active components, respectively, were obtained for the above five classic prescriptions, and the numbers of drug targets were 7426, 1435, 9544, 6619, and 2427, respectively. Finally 4001 HCC disease targets were screened out. There were 260, 169, 276, 242, and 192 intersecting targets, respectively, between the five prescriptions and the HCC disease targets, and the survival analysis on the GEPIA online website obtained the common hub genes of PIK3CA, SRC, MAPK1, MAPK3 (all P＜0.05) and AKT1 (P＞0.05). Quercetin was the common active component of the five prescriptions, and isobavachin and Kanzonol W were the common active components of Xiaoyao powder combined with Sijunzi decoction, Longdan Xiegan decoction combined with Xiayuxue decoction, and Wupi decoction combined with Sijunzi decoction; the results of molecular docking showed that the above three components had a strong ability of binding to PIK3CA and SRC. GO enrichment analysis showed that these targets were involved in various biological processes including drug response, protein phosphorylation, inflammatory response, and angiogenesis, and KEGG enrichment analysis showed that the common pathways involved were cancer pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, Ras signaling pathway, HIF-1 signaling pathway, hepatitis B pathway, and hepatitis C pathway. ConclusionQuercetin, isoflavone, and Kanzonol W have the potential mechanism of action involving multiple targets and pathways in the treatment of HCC.

Autophagy has become a research hotspot in the prevention and treatment of tumor in recent years. With the help of the bidirectional regulatory effect of autophagy, it can not only provide energy and a stable internal environment for normal and tumor cells by clearing misfolded proteins and damaged organelles in cells, but also induce autophagic death of tumor cells. Traditional Chinese medicine has advantages over Western medicine in better mediating autophagy to inhibit tumor development and progression, with the features of low toxicity, multiple targets, and multiple pathways. With an increasing number of studies on autophagy in traditional Chinese medicine, this article reviews the research advances in the effect of traditional Chinese medicine in autophagy in liver cancer in the past 10 years and explores and analyzes existing problems, hoping to provide a reference and new ideas for subsequent research on liver cancer.

"State-target-cause-result"is a new clinical theory combining macroscopic and microscopic syndrome differentiation based on the holistic view of traditional Chinese medicine combined with Western medical research.The"inflammation-cancer transformation"of chronic pancreatitis is a complex pathological process that is associated with the interaction between the pancreas and various pathological factors and multiple objects,involving the imbalance of multiple homeostasis.The microscopic process of"inflammation-cancer transformation"in chronic pancreatitis is the"target,"whereas various factors that could induce its occurrence under chronic inflammatory conditions are the"state."The"inflammation-cancer transformation"of chronic pancreatitis is summarized as yin and yang imbalance,qi movement disorder,endogenous dampness,heat,blood stasis,and turbid phlegm stagnation,unresolved congestion resulting in deficiency caused by stagnation,intermingled deficiency and excess,and internal cancer toxin generation.This paper elucidates the pathogenesis and intervention strategies of the"inflammation-cancer transformation"of chronic pancreatitis from a macro perspective of"state,"focusing on reducing the impact of"state"imbalance on the"target"to establish a balanced pancreas-immune-microbiota state.The aim is to broaden the theory for exploring the mechanism and drug development related to chronic pancreatitis"inflammation-cancer transformation"in both traditional Chinese and Western medicine.
