OBJECTIVE To provide an experimental basis for quality control， clinical application and development of hepatoprotective drugs derived from Thesium chinense Turcz.METHODS Network pharmacology was adopted to predict and screen potential hepatoprotective constituents and their action targets of T. chinense Turcz. A liver-injured model of transgenic zebrafish Tg （ fabp10a ： dsRed ） with fluorescent-labeled liver was induced by 4 mmol/L isoniazid. The relative liver fluorescence area and relative fluorescence intensity of zebrafish larvae， as well as the levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， glutathione （GSH） and interleukin-6 （IL-6） were taken as indexes to evaluate the hepatoprotective activity of potential active constituents. High-performance liquid chromatography was used to determine the contents of hepatoprotective active constituents in 17 batches of T. chinense Turcz. medicinal materials from different producing areas.RESULTS Four potential hepatoprotective constituents including kaempferol-3- O -glucorhamnoside （KOG）， kaempferol-3，7-di- O -glucoside （KDG）， buddleoside （BUD） and apigenin-5- O -neohesperidoside （AON） were screened out via network pharmacology， and their core targets involved mitogen-activated protein kinase 1， nuclear factor-κB subunit 1， etc. Pharmacodynamic verification results showed that 25 μmol/L KOG， BUD， AON and 50 μmol/L KDG could significantly increase the relative liver fluorescence area and relative fluorescence intensity of liver-injured model larvae （ P ＜0.05）， reduce the levels of AST， ALT and IL-6 （ P ＜0.05）， and elevate the GSH level （ P ＜0.05）. Content determination results indicated that KOG could be detected in all 17 batches of T. chinense Turcz. medicinal materials， with contents ranging from 0.097 0 to 8.082 0 mg/g；KDG， AON and BUD were not detected in partial batches of samples， and their contents in detectable batches were 0.019 3-0.123 2 mg/g， 0.018 4-0.109 1 mg/g and 0.385 1-1.189 3 mg/g， respectively.CONCLUSIONS KOG， KDG， AON and BUD in T.chinense Turcz. may be its potential hepatoprotective active constituents. Among them， KOG can be detected in T.chinense Turcz. medicinal materials from different producing areas with relatively high content， which can be used as the main marker constituent for evaluating the hepatoprotective effect of T.chinense Turcz.

Objective:To identify differentially expressed genes (DEGs) associated with the progression of synovitis in RA by using bioinformatics analysis and explore the effects of DMARDs such as methotrexate, tocilizumab and rituximab on the DEGs in RA synovium.Methods:RA expression profile microarray data GSE7307、GSE12021、GSE55457、GSE55235、GSE77298、GSE89408 were acquired from the public gene chip database (GEO), including 113 synovial tissue samples from RA and 70 healthy controls (HC). At the same time, synovial expression microarrays GSE45867, GSE24742 and GSE97165 after DMARDs treatment were obtained. These data included 8 samples treated with methotrexate, 12 treated with tocilizumab, 12 treated with rituximab and 19 treated with combined tDMARDs. R software was used to screen DEGs and Venn plots using gene ontology function enrichment and Kyoto encyclopedia of genes and genomes pathway enrichment analysis. Hub genes were selected by STRING online analysis tool and Cytoscape software.Results:Compared with HC, 797 DEGs were up-regulated and 434 DEGs were down-regulated in the synovial tissue of RA. These DEGs were mainly enriched in T cell activation, immune response-activating cell surface receptor signaling pathway. Using Cytoscape and cytoHubba to obtain 5 sets of DEGs based on the STRING database model, the degree algorithm screened out 10 hub genes: LCK, SYK, PTPRC, HLA-DRA, LYN, NCAPG, TOP2A, JUN, CXCR4, CCNB1. Methotrexate treatment significantly up-regulated 20 DEGs and down-regulated 30 DEGs. Rituximab treatment up-regulated 100 DEGs and down-regulated 55 DEGs. Tocilizumab treatment up-regulated 91 DEGs and down-regulated 317 DEGs. These altered DEGs were enriched in regulating cell adhesion, leukocyte-cell adhesion, leukocyte transfer, and insulin-like growth factor receptor signaling pathways. It was worth noting that after treatment, a total of 306 high-expressing DEGs were down-regulated, and 36 low-expressing DEGs were up-regulated.Conclusion:LCK, insulin-like growth factor receptor signaling pathway, etc. are the responsible molecular mechanisms and key pivot genes for the occurrence and development of RA, and the treatment of DMARDs, which are closely related to the response of RA to the treatment of DMARDs.
