Résumé
Objective: Based on the network pharmacology research method, combined with the theory of traditional Chinese medicine, to explore the mechanism of the interaction of Huobahuagen Tablets (HBHGT) for treating different diseases with same method between the lupus erythematosus (LE) and rheumatoid arthritis (RA). Methods: The components in HBHGT and their targets were collected by using TCMSP, Chinese Herb Dictionary, and other databases in combination with literature. Disease-related targets for lupus erythematosus and rheumatoid arthritis were collected using databases such as CTD, PubMed, and Drugbank in conjunction with literature. The herb-ingredient-target network and drug-target-disease interaction PPI network were constructed by Cytoscape software, and the gene function and signaling pathway of the constructed network were analyzed. ClueGO plugin in Cytoscape software was used for GO analysis and Pathway analysis. Results: The main components of torch flower roots were epicatechin, triptolide and triptonide, and 138 key targets were obtained. Through GO analysis and Pathway analysis, it was found that HBHGT for treating different diseases with same method between the lupus erythematosus and rheumatoid arthritis involved 17 common targets such as EGFR, CRK, and LCK, and its mechanism may be related to biological processes such as phosphoprotein binding, ERBB2 signaling pathway, peptidyl tyrosine autophosphorylation, and receptor tyrosine kinase signaling pathway, FGFR3 signaling pathway, Fcε receptor (FCERI) signaling pathway and other pathways. Receptor tyrosine kinase signaling pathway was the main pathway of HBHGT for treating different diseases with same method. Conclusion: This study confirmed from the two aspects of target and pathway that HBHGTs had great similarities in the treatment of RA and LE. Among them, EGFR, CBL, LCK, and other targets and EGFR-related signaling pathways were the key targets and pathways of HBHGT for "different diseases with the same treatment".
Résumé
OBJECTIVE:To establish the HPLC fingerprints for Huobahuagen tablets intermediate. METHODS:HPLC was per-formed on Inertsil ODS-4 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid (gradient elution) at the flow rate of 0.75 mL/min. The detection wavelength was set at 220 nm,and column temperature was 30 ℃. The sample size was 10 μL. Using wilforgine as reference,HPLC chromatograms of 10 batches of samples were determined. Common peak identification and similarity evaluation were performed by using Similarity Evaluation System for TCM Chromatographic Fingerprint (2004 A edi-tion). RESULTS:There were 25 common peaks in HPLC chromatograms of 10 batches of samples,and similarity degrees were higher than 0.9. After validated,HPLC chromatograms of 10 batches of samples were in good agreement with control fingerprints. CONCLUSIONS:The established fingerprint can provide reference for identification and quality evaluation of Huobahuagen tab-lets intermediate.
