摘　　要：目的观察软坚消瘿汤对实验性自身免疫性甲状腺炎(EAT)大鼠自身抗体、白细胞介素-1(IL-1)、肿瘤坏死因子-α(TNF-α)和凋亡蛋白Fas、Fasl的影响,从细胞因子和凋亡蛋白关系角度探讨其作用机制。方法SPF级SD雌性大鼠60只分为正常组、模型组,模型组运用甲状腺球蛋白与弗氏佐剂混合免疫注射法,联合饮用高碘水模拟大鼠EAT。造模完成后的大鼠分为中药组、雷公藤组、模型组。酶联免疫法检测甲状腺抗体、IL-1及TNF-α水平,免疫组化染色法检测大鼠甲状腺细胞Fas、Fasl变化。结果软坚消瘿汤能显著降低EAT大鼠血清自身抗体、IL-1及TNF-α水平,降低甲状腺细胞Fas、Fasl表达。结论软坚消瘿汤通过降低EAT血清中自身抗体及细胞因子水平,致使凋亡相关蛋白Fas、Fasl表达下降,从而起到减轻甲状腺细胞凋亡作用。Objective To evaluate the therapeutic effect of Xiaoying Ruanjian Decoction on experimental autoimmune thyroiditis （EAT） from the levels of autoantibodies, interleukin-1, tumor necrosis factor-α and apoptosis-regulated proteins Fas/Fasl of EAT rats, and investigate the mechanism from the relation between cytokines and apoptosis-regulated proteins. Methods Sixty SD female rats of SPF level were divided into normal group and model group. An animal model of EAT in rats was developed by injecting thyroglobulin mixed with Freund’s adjuvant immunization and drinking periodate water. The rats modeled were divided into Chinese medicine group, western medicine group and model group. The levels of autoantibodies, interleukin-1, tumor necrosis factor-α were detected with enzyme-linked immunosorbent assay. The level change of Fas/Fasl in the thyroid of rat was observed with immunohistochemical staining. Results Ruanjian Xiaoying Decoction significantly reduced the levels of autoantibody, interleukin-1, tumor necrosis factor-α and lowered the expression of Fas and Fasl in thyroid cells. Conclusion Ruanjian Xiaoying Decoction alleviates the levels of apoptosis-regulated proteins Fas/Fasl by decreasing the relative expression of antibodies and cytokines in serum levels, which plays a role in reducing apoptosis of thyroid cells.
