摘要: 阐释天麻-附子祛风通络药对抗类风湿性关节炎(RA)的作用机制。采用CIA法复制RA大鼠模型,并辅以风寒湿刺激条件。以关节炎指数≥4筛选RA大鼠模型,分为正常组、模型组以及天麻-附子药对各剂量配比组。ELISA法检测各组大鼠血清RF、CRP、TXB2、PGE2和PGI2的变化。RT-qPCR法检测各组大鼠全血COX-1和COX-2 mRNA表达的变化。结果表明:给药21天之后,与模型组相比,各剂量配比组大鼠关节炎指数下降,体重增加,明显降低血清RF、CRP、PGE2、PGI2水平,并能下调各组大鼠全血COX-2 mRNA的表达。因此,天麻-附子药对通过下调COX-2 mRNA表达,降低炎症因子PGE2和PGI2的含量而具有抗炎抗风湿作用。

Abstract:

To explain the mechanism of GRHP against rheumatoid arthritis (RA).RA rats’ model was constructed by collagen-induced arthritis (CIA) method and wind-cold-dampness stimulant condition,and screened by arthralgia index (AI) more than four.RA rats were classified to four groups such as model and three dose-ratio groups of GRHP except for normal group.Blood serum cytokine level of each rat was determined by ELISA approach,for example,rheumatoid factor (RF),C-reactive protein (CRP),thromboxane B2 (TXB2),prostaglandin E2 (PGE2) and prostacycline (PGI2).Whole blood COX-1 and COX-2 mRNA expression of each rats was determined by Real time quantitative PCR approach.As was shown in results,AI and blood serum cytokine level such as RF,CRP,PGE2 and PGI2 were markedly decreased,whole blood COX-2 mRNA expression reduced,body weight increased in the rats of dose-ratio groups by comparing with model group twenty-one day after intragastric administration.Therefore,GRHP has anti-inflammatory and anti-rheumatoid arthritis effects by downregulating COX-2 mRNA expression and decreasing proinflammatory factor level such as PGE2,PGI2,et al.
