Methods: Adjuvant arthritis(AA) rat models were induced and used as rat models of RA. Rats were randomly divided into a normal group, a model group, a moxibustion group and a saline group. Rats in the normal and model groups were not treated; rats in the moxibustion group accepted treatment by moxibustion at Zusanli(ST 36) and Shenshu(BL 23) after modeling; rats in the saline group were injected with 0.15 mL saline to the bottom of the left hind paw and had no other treatments. Hematoxylin-eosin(HE) staining was used to observe the histopathological changes of rats' ankle joints under light microscope. Immunohistochemistry was used to observe the expressions of TNF-α and NF-κB in ankle joints of rats. Results: Compared with the normal group, the rats' ankle joints in the model group showed disorganization, joint surface defect, and significantly increased mean optical density(MOD) of TNF-α and NF-κB(all P〈0.05). After moxibustion treatment, rats in the moxibustion group showed repaired ankle tissues, smooth joint surface without defects, decreased MOD of TNF-α and NF-κB than those in the model group(all P〈0.05). Rats in the saline group had no damage to ankle joints, while TNF-α and NF-κB were significantly different from those in the model group(P〈0.05). Conclusion: Moxibustion could down-regulate the expressions of NF-κB and TNF-α protein in ankle joints of RA rats, and produce an anti-inflammatory effect to promote tissue repair.展开更多
