摘　　要：Objective： To observe the effect of moxibustion on the expressions of tumor necrosis factor-α（TNF-α） and nuclear transcription factor kappa B（NF-κB） proteins in ankle joints of rats with rheumatoid arthritis（RA）, and to explore the anti-inflammatory mechanism of moxibustion in the treatment of RA. 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.目的:通过观察艾灸对类风湿关节炎(RA)大鼠踝关节组织肿瘤坏死因子-α(TNF-α)和核转录因子kappa B(NF-κB)蛋白表达的影响,探讨艾灸治疗类风湿关节炎的抗炎机制。方法:以佐剂性关节炎(AA)作为类风湿关节炎大鼠模型,复制RA大鼠模型。将大鼠随机分为正常组、模型组、艾灸组和盐水组。正常组和模型组不做治疗;艾灸组造模后予以艾灸足三里、肾俞治疗;盐水组予左后足趾底部注入生理盐水0.15 m L,不做其他处理。应用苏木精-伊红(HE)染色,光镜下观察大鼠踝关节组织病理学变化;采用免疫组化法观察大鼠踝关节组织TNF-α和NF-κB蛋白表达。结果:与正常组比较,模型组大鼠踝关节组织结构破坏,关节表面有缺损,TNF-α和NF-κB平均光密度(MOD)明显增高(均P<0.05);艾灸组大鼠经艾灸治疗后,踝关节组织修复,关节表面光滑未见缺损,TNF-α和NF-κB的MOD较模型组降低(均P<0.05);盐水组大鼠踝关节组织正常无损害,TNF-α和NF-κB与模型组比较有显著性差异(P<0.05)。结论:艾灸能够下调RA大鼠踝关节组织NF-κB和TNF-α蛋白表达,以发挥抗炎作用,促进组织修复。
