RESUMO

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.

RESUMO

BACKGROUND:Compared with bone marrow transplantation, peripheral blood stem cel transplantation has its own advantages, including rich resources of stem cel s from the peripheral blood, convenient and easy col ection, without anesthesia, smal trauma, easily accepted, high safety, and easy to restore the patient’s hematopoietic system. OBJECTIVE:To observe the function and safety of autologous peripheral blood mononuclear cel s in the treatment of patients with decompensated cirrhosis. METHODS:Four patients with decompensated liver cirrhosis were selected from November 2010 to July 2011 in the First Affiliated Hospital of Dalian Medical University, aged 31-67 (averagely 44 years). Among them, three cases had hepatitis B, and another one had autoimmune liver disease. Peripheral blood stem cel s were col ected after being mobilized by granulocyte colony stimulating factor. Then, autologous peripheral blood stem cel s were transplanted via a hepatic artery catheter. RESULTS AND CONCLUSION:There were no adverse reactions such as fever, bleeding and nausea after peripheral blood stem cel col ection and hepatic artery transplantation. Symptoms such as fatigue, poor appetite and abdominal distension gradual y improved at 1, 3 and 6 months after transplantation. Liver function and liver fibrosis indexes were improved to some extent after transplantation.
