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.
RÉSUMÉ
Sanrentang， originally contained in the Regulations on Febrile Diseases written by WU Ju-tong in the Qing dynasty， was composed of eight traditional Chinese herbs to treat damp-warm diseases. It is a treatment method of gradually clearing away damp heat of tri-jiao， with characteristics of separating dispersion and mobilizing discharge. "Separating dispersion" means dispersion in separated ways， with different ways to eliminate dampness to export the dampness， heat， evil and turbid out of the body. "Mobilizing discharge" means discharge to stretch and unblock the Qi， to get rid of dampness and evil. It can be seen， Sanrentang， as a desiccating formula， taking "separating dispersion and mobilizing discharge" as the cubic basis， has a significant effect on both internal and external dampness associated with pathogenic heat syndrome， and its clinical application is quite extensive. After consulting the data of the past 10 years， the authors gave a brief overview on the syndrome theory， clinical application and pharmacological effects of Sanrentang， and elaborated the therapeutic effect and pharmacological effect of Sanrentang in the clinical application of upper， middle and lower Tri-jiao respectively， providing theoretical reference for effective development and utilization of Sanrentang. Coronavirus disease-2019（COVID-19） swept the world in early 2020 and it is a great challenge for the medical community to seek for effective prevention and treatment methods. For COVID-19， although the cause of the disease belongs to the Qi of "pestilence"， many doctors have different opinions on the pathogenic characteristics. However， they all agree with the clinical characteristics of "dampness". COVID-19， which has the attribute of "dampness evil"， is so sticky that it can't be cured at once. In addition to the main symptoms such as fever and cough， it is also characterized by the middle-jiao dampness symptoms such as poor appetite， fullness of abdomen， loose stool and diarrhea. It is worthy to further explore the application prospect of Sanrentang in COVID-19 prevention and treatment.

<p><b>OBJECTIVE</b>To explore the effect of Shenqi Fuzheng Injection (SFI) on gene expression profile of liver tissue with metastatic carcinoma in mice.</p><p><b>METHODS</b>Twenty liver metastatic carcinoma model mice were established by splenectomy after their spleens were injected with 0.2 mL colon cancer C26 cell strain oncocyte liquid, then they were randomly divided into the model group and the SFI group. Starting from the 5th day after modeling, mice in the model group and the SFI group were given via intraperitoneal injection once every other day with physiological saline and SFI respectively. All the mice were sacrificed at the 15th day and the gene profile of metastatic liver carcinoma tissue in the two groups were screened by whole genome chip technique.</p><p><b>RESULTS</b>(1) The model establishing successful rate reached 100%; (2) Gene expression showed that as compared with the model group, in the SFI group, 123 genes were up-regulated, with 52 of them registered to Ensemble, while only one gene was down-regulated and registered to Ensemble was none.</p><p><b>CONCLUSION</b>SFI plays its role of anti-tumor mainly by upregulating several relative genes to promote apoptosis of tumor cells and stabilizing chromosomes.</p>
