ABSTRACT
The study aims to investigate the effects and potential mechanism of raw and processed Aconitum pendulum Busch on rheumatoid arthritis(RA) and analyze their toxicity attenuating and efficacy retaining effects. The bovine type â
¡ collagen-induced arthritis(CIA) rat model was established. The weight, cardiac index, immune organ index, and arthritis index of the rats were recorded and calculated after administration. ELISA was used to measure the expressions of creatine kinase(CK), cardiac troponin T(cTnT), and multiple factors. The pathological morphological changes in heart tissue and ankle joint tissue were observed by hematoxylin-eosin staining. Connexin 43(Cx43) expression in the hearts of CIA rats was detected via immunohistochemical method. The levels of endogenous metabolites in the serum of CIA rats were detected by UPLC-Q-TOF-MS. Potential biomarkers were screened, and related metabolic pathways were analyzed. The results showed that raw A. pendulum could induce local myocardial fiber degeneration and necrosis, increase the cardiac index, decrease the average positive area of Cx43 expression significantly, and increase the expressions of CK and cTnT in cardiac tissue of rats. Meanwhile, raw A. pendulum could decrease the immune organ index, interleukin-6(IL-6), and other inflammatory cytokine contents in the serum and improve the damaged synovium and joint surface of CIA rats, with toxicity and efficacy coexisting. The Zanba stir-fired A. pendulum could reduce the index of arthritis, immune organ index, and content of IL-6 and inflammatory cytokines in serum and improve damaged synovium and joint surface of CIA rats with no obvious cardiac toxicity, showing significant toxicity attenuating and efficacy retaining effects. A total of 19 potential biomarkers of raw A. pendulum and Zanba stir-fired A. pendulum against RA were screened by serum metabolomics, including glycerophospholipid metabolism, glycine, serine, and threonine metabolism, arginine and proline metabolism, and steroid hormone synthesis. In conclusion, Xizang medicine A. pendulum is preventive and curative for RA. Raw A. pendulum has certain cardiotoxicity, and Zanba stir-fired A. pendulum has significant toxicity attenuating and efficacy retaining effects. The anti-RA mechanism may be related to the regulation of glycerophospholipid and amino acid metabolism.
