Аннотация
BACKGROUND: The Ermiao San Series of Formulas (ESSF) refers to Ermiao San (TS), Sanmiao Wan (TW), and Simiao Wan (FW), which are widely used traditional Chinese medicine (TCM) formulas for treating rheumatoid arthritis (RA). However, the therapeutic advantages and underlying mechanisms of ESSF treatment are unclear, especially regarding the improper selection of these three formulas when treating RA.
PURPOSE: To explore the efficacy and mechanisms of ESSF treatment for RA.
METHODS: Complete Freund's adjuvant was used to induce RA in rats. Chinmedomics strategy, which included metabolomics, serum pharmacochemistry of TCM, molecular docking, western blotting and qPCR, was applied to reveal the therapeutic advantages, pathways, and targets of ESSF.
RESULTS: In the early stages of treatment, TS quickly reduced joint swelling and the arthritis score index and regulated pathways such as arachidonic acid metabolism and purine metabolism. TW increases the regulation of tryptophan metabolism and pyrimidine metabolism pathways, promoting the recovery of the thymus and spleen. FW increases the regulation of linoleic acid metabolism and has the greatest effect on immune organ and bone recovery. In addition, 54, 67, and 86 bioactive compounds were detected in the serum from TS, TW, and FW, respectively. Berberine, phellodendrine, atractylolide III, limonin, 25R-inokosterone, coixol, and stigmasterol were found to act on the key enzymes COX-2, mPGES-1, ALOX5, and XDH in arachidonic acid metabolism and purine metabolism pathways. Western blot and qPCR results showed that ESSF can reduce the activity of these targets, thereby inhibiting the expression of the inflammatory factors IL-1β, IL-6, IL-17, and TNF-α; the tissue injury factors MMP-3 and CRP; and the rheumatoid factors CCP Ab and RF, thereby achieving anti-RA efficacy.
CONCLUSION: ESSF has a good therapeutic effect on RA. TS focus on rapid swelling reduction in the early stages of RA, TW focus on the recovery of immune organ function, and FW can be used for bone recovery in the later stage of RA treatment. The key mechanism of treating RA is that ESSF reduces the activity of COX-2, mPGES-1, ALOX5, and XDH. These findings provide valuable guidance for targeted therapy for RA and for the clinical application of ESSF.
