摘　　要：目的探讨苗药金乌健骨胶囊对胶原诱导关节炎(collagen-induced arthritis,CIA)模型大鼠肠道、滑膜炎症及参与NF-κB信号通路基因IL-17受体信号分子ACT1(nuclear factor kappa B activator 1,ACT1)、泛素化TRAF6(TNF receptor associated factor 6,TRAF6)、转化生长因子β激活激酶1(transforming growth factor-β-activated kinase 1,TAK1)、核因子-κB上游激酶(IκB kinaseα,IKKα)、核因子κB/p65、核因子κB/p50表达的影响。方法将70只SPF级6~8周龄雌性Wistar大鼠随机分为7组,分别为空白对照组、模型组、金乌健骨胶囊低剂量组、金乌健骨胶囊中剂量组、金乌健骨胶囊高剂量组、甲氨蝶呤组及益生菌组,每组10只。适应性喂养后除空白对照组外,其余6组构建CIA模型,两次免疫造模成功后分别进行药物金乌健骨胶囊、甲氨蝶呤、益生菌灌胃治疗,治疗4周后静脉取血,处死大鼠,分离大鼠滑膜组织及肠道组织。利用HE染色法检测大鼠滑膜及大肠组织病理情况;ELISA法检测大鼠血清TGF-β1、IL-1α、IL-17α、IL-21、IL-23的含量;Western blot法检测大鼠肠道组织ACT1、TRAF6、TAK1、IKKα、P65、P50蛋白的表达水平;RT-qPCR法检测大鼠肠道ACT1、TRAF6、TAK1、IKKα、P65、P50基因的表达情况。结果滑膜病理结果显示,与模型组相比,金乌健骨胶囊中、高剂量组和甲氨蝶呤组炎性浸润、增生、血管新生组织有明显改善;肠道病理结果显示,与模型组相比,金乌健骨胶囊低、中、高剂量组及甲氨蝶呤组、益生菌组肠道组织细胞可见少量炎性细胞浸润,肠道组织细胞病变情况较模型组有不同程度的改善;ELISA结果显示,与模型组相比,各给药组血清含量显著降低(P<0.05或P<0.01);Western blot结果显示,各给药组大鼠肠道组织ACT1、TRAF6、TAK1、IKKα、P65、P50的蛋白表达显著降低(P<0.05或P<0.01);RT-qPCR结果显示,各给药组ACT1、TRAF6、TAK1、IKKα、P65、P50基因的表达显著降低(P<0.05或P<0.0Objective To investigate the effects of Jinwu Jiangu Capsule(JWJGC),the medicine from the Chinese Miao nationality,on intestinal and synovial inflammation in rat models with collagen-induced arthritis(CIA),and on the expressions of genes involved in NF-κB signaling pathway,including IL-17 receptor signaling molecule nuclear factor kappa B activator 1(ACT1),TNF receptor associated factor-6(TRAF6),transforming growth factor-β-activated kinase 1(TAK1),and the nuclear factors of IκB kinaseα(IKKα),κB/p65,andκB/p50.Methods Seventy female Wistar rats aged 6-8 weeks of SPF grade were randomly divided into seven groups:blank control group,model group,low-,medium-and high-dose JWJGC groups,methotrexate group,and probiotic group,with 10 rats in each group.After adaptive feeding,except for the blank control group,CIA models were established in the other six groups.After two successful immune modeling attempts,rats in JWJGC groups,methotrexate group,and probiotic group were treated with JWJGC,methotrexate,and probiotics by gavage,respectively.After four weeks of treatment,blood of rats was collected via vein.Then the rats were sacrificed and the synovial tissues and intestinal tissues were separated from the bodies.The histopathological condition of rat synovium and intestine was checked by HE staining,the content of serum TGF-β1,IL-1α,IL-17α,IL-21,and IL-23 in rats was tested by ELISA,the expression levels of ACT1,TRAF6,TAK1,IKKα,P65,and P50 proteins in rat intestinal tissues were determined by Western blot,and the expression levels of ACT1,TRAF6,TAK1,IKKα,P65,and P50 genes in rat intestinal tissues were checked by RT-qPCR.Results The synovial pathological results showed that the medium-and high-dose JWJGC groups and methotrexate group had a significant reduction in inflammatory infiltration and proliferation,and a significant improvement in angiogenesis compared with the model group;the intestinal pathological results showed that a small amount of inflammatory cell infiltration could be seen in intestinal tissue
