According to professor DONG Ting-yao,s understanding,syndrome differentiation characteristic,principle of treatment and so on to the young child spleen gastric disease,the paper lifted the clinical application of rising jin and activating spleen,harmonizing ying and noruishing stomach,dispersing stagnated liver-qi and regulating spleen,strengthening earth to generate metal,clearing spleen and dissipating hygrosis,invigorating spleen and benefiting qi.Professor DONG Ting-yang cured various kinds of disease through regulating spleen and stomach.

Objective To predict the potential mechanism of Yifei Sanjie prescription in the treatment of lung adenocarcinoma based on network pharmacology,and to verify one of the key signal pathways,Janus protein tyrosine kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3),by cell experiments in vitro.Methods To screen the main active components and potential action targets of Yifei Sanjie prescription,with traditional Chinese medicine system pharmacological database(TCMSP).To search and retrieve the main targets of lung adenocarcinoma,with human genetic database(GeneCards)and online human Mendelian genetic database(OMIM).To obtain the intersection targets by screening and apply Wayne diagram,then analysis the topology and establish the traditional Chinese medicine-active compound-target network diagram by using of Cytoscape 3.7.2 software.To construct the protein-protein interaction(PPI)network,with the protein-protein interaction platform(STRING)and Cytoscape3.7.2 software.To analyze the functional enrichment of gene ontology(GO)and Kyoto encyclopedia of genes and genomes(KEGG),with the Metascape database.To carry out the molecular docking verification by using of Vina1.2.3 software.Using CCK-8 method to detect the effect of Yifei Sanjie prescription on cell activity.Using the cell scratch test to observe the effect on cell migration.And using Western blot method to test the expression of p-STAT3,STAT3,p-JAK2,JAK2 and VEGF-A.Results 94 active components,329 related drug targets and 1358 lung adenocarcinoma targets were obtained from Yifei Sanjie prescription,among which,150 of them intersected.PPI network visualization analysis shows that the potential key targets of Yifei Sanjie prescription in the treatment of lung adenocarcinoma are protein kinase B1(AKT1),β-actin(ACTB),tumor suppressor gene p53(TP53),serum albumin(ALB),caspase-3(CASP3)and vascular endothelial growth factor A(VEGFA).KEGG enrichment analysis screened 138 related signal pathways,indicating that JAK/STAT signaling pathway may play a key role in the treatment of lung adenocarcinoma with Yifei Sanjie prescription.Molecular docking results showed that quercetin,luteolin,and ursolic acid had good binding activities with JAK2 and STAT3.The cell experiment showed that compared with the blank group,Yifei Sanjie prescription could significantly inhibit the activity of A549 cells,inhibit the migration of A549 cells,and decrease the expression of p-JAK2/JAK2,p-STAT3/STAT3 and VEGF-A protein.In addition,Colivelin,an activator of JAK2/STAT3 pathway,could reverse the effect of Yifei Sanjie prescription on the expression of A549 related proteins.Conclusion Yifei Sanjie prescription has the characteristics of multi-component,multi target and multi pathway in the treatment of lung adenocarcinoma,and its mechanism may be related to the down-regulation of p-JAK2,p-STAT3 and VEGF-A protein expression,thereby inhibiting cell proliferation and migration.
