METHODS: We utilized moxibustion treatment in RA rat models using the Zusanli(ST36) and Shenshu(BL23) acupoints. Hematoxylin and eosin(HE) staining was used to observe the pathological changes of the synovial tissue under a section light microscope, and pathological scoring was performed according to the grading standard of the degree of synovial tissue disease. Enzyme-linked immunosorbent assay(ELISA) was applied to verify the efficacy of moxibustion in reducing inflammation. Quantitative real-time polymerase chain reaction(q RTPCR) was used to detect the expression of the TIM-3/TLR4-My D88-NF-κB signaling pathway-related molecules, and Western blot was used to detect the contents of synovial NF-κB. RESULTS: We established the Freund's complete adjuvant(FCA)-induced RA model in rats. The expression level of M1 polarization signaling pathway TLR4-My D88-NF-κB and the inflammatory factors interleukin-12(IL-12), tumor necrosis factor alpha(TNF-α), and tumor necrosis factor beta(TNF-β) were significantly increased in the RA model. After moxibustion treatment, the expression level of TLR4-My D88-NF-κB was significantly decreased, and the inflammatory factors IL-12, TNF-α, and TNF-β were decreased, but the expression level was significantly increased in the RA model. When TIM-3 expression was inhibited, the expression level of TLR4-My D88-NF-κB, and the inflammatory factors IL-12, TNF-α, and TNF-β were not suppressed, even after moxibustion treatment. CONCLUSIONS: Moxibustion regulates the key target TIM-3 by acting on the Zusanli(ST36) and Shenshu(BL23) points, thereby inhibiting the M1 polarization of macrophages;that is, it inhibits the TLR4-My D88-NF-κB signaling pathway, and finally achieves alleviation of pathological changes and anti-inflammatory effects.展开更多
