RESUMO
Objective:To explore the mechanism of Yiqi Yangyin decoction in the treatment of thyroid cancer by means of network pharmacology and molecular docking technique.Meth-ods:the chemical constituents of 10 kinds of Yiqi Yangyin decoction were searched by HERB database,the active components were screened by PubChem and SwissADNE,and the action targets of active components were predicted by Swisstargetprediction.The disease targets after operation of thyroid cancer were obtained by searching the databases of GeneCards,OMIM,Dis-GeNET and DrugBank.The intersection target of drug and disease was obtained by Venny2.1.0 platform,the intersection target protein interaction network was constructed by String database,and the core target protein was screened by Cytoscape3.9.1,the drug-active ingredient-target network map was constructed by Cytoscape3.9.1,and the key active components were obtained;the enrichment analysis of GO and KEGG was carried out using Metascape database;and the molecular docking verification of key targets and key components was carried out.Results:157active components of Yiqi Yangyin decoction were obtained,and 507targets of active compo-nents were predicted,1817 targets of thyroid cancer-related diseases and 154targets of drug-disease intersection were obtained.The key target genes of SRC,HSP90AA1,PIK3R1,PIK3CA and AKT1 were obtained by PPI analysis.Quercetin,kaempferol and luteolin were the key active components.Molecular docking showed that the key targets and key active components had good affinity.KEGG enrichment analysis showed that cancer pathway,PI3K-Akt pathway and HIF-1 pathway were the key pathways of drug action.Conclusion:Yiqi Yangyin decoction can play a therapeutic role in anti-inflammation,anti-tumor and improving tissue microenvironment with multi-components,multi-targets and multi-pathways.
RESUMO
Objective:To explore the effect of self-made Yiqi Yangyin Decoction on immune function, serum tumor markers and toxic and side effects of chemotherapy in patients with advanced gastric cancer chemotherapy.Methods:A total of 88 patients with advanced gastric cancer who met the inclusion criteria in the hospital between December 2018 and December 2020 were divided into two groups according to the random number table method, with 44 in each group. The control group was treated with chemotherapy, and the observation group was given self-made Yiqi Yangyin Decoction on the basis of the control group. The two groups were treated for 4 consecutive cycles with 3 weeks as 1 cycle. The Traditional Chinese Medicine (TCM) symptoms were scored before and after treatment, and the levels of IgG, IgA and IgM were detected by immunoturbidimetry. The levels of carcinoembryonic antigen (CEA) and cancer antigen 125 (CA125) were detected by ELISA. The gastrointestinal reactions, thrombocytopenia, anemia, leukopenia and neurotoxicity were recorded and evaluated during treatment, and the clinical efficacy was assessed.Results:The total effective rate was 81.8% (36/44) in observation group and 61.4% (27/44) in control group (χ 2=4.53, P<0.05). After treatment, the scores of stomachache and gastric distension, poor appetite, shortness of breath, and drooping spirit in observation group were significantly lower than those in the control group ( t=17.28, 11.91, 5.02, 5.65, all Ps<0.001) while the levels of serum IgG [(9.39±0.46)g/L vs. (8.54±0.23) g/L, t=10.96], IgA [(1.35±0.42) g/L vs. (1.07±0.15) g/L, t=6.90] and IgM [(0.92±0.09) g/L vs. (0.78±0.10) g/L, t=4.17] were significantly higher than those in the control group ( P<0.01). The levels of serum CEA [(9.07±1.01) μg/L vs. (14.89±2.13) μg/L, t=16.38] and CA125 [(24.87± 4.68) kU/L vs. (30.75±5.33) kU/L, t=5.50] were significantly lower than those in the control group ( P<0.01). During treatment, the toxic and side effects of gastrointestinal reactions, thrombocytopenia, anemia, leukopenia and neurotoxicity were significantly lower in the observation group than those in the control group ( Z=18.52, 2.54, 3.12, 3.84, 2.34, P<0.05). Conclusion:Self-made Yiqi Yangyin Decoction can improve the TCM symptoms, enhance the immunity, reduce the levels of serum tumor markers, and relieve the toxic and side effects of chemotherapy of patients undergoing chemotherapy for advanced gastric cancer.
