Abstract:
Objective:To investigate the anti-inflammatory effects of Duhuo Jisheng Decoction on type Ⅱ collagen emulsion induced arthritis (CIA) model rats from the perspective of M1/M2 macrophage balance mediated development of rheumatoid arthritis.Methods:SD rats were divided into a normal group of 8 and a model group of 32. The CIA model was established using collagen antibody induction method for modeling. The successfully modeled rats were randomly divided into model group, methotrexate group, and Duhuo Jisheng Decoction medium- and high-dosage groups using a random number table method, with 8 rats in each group. Duhuo Jisheng Decoction medium- and high-dosage groups were orally administered with Duhuo Jisheng Decoction at dosages of 13.5 and 27.0 g/kg, once a day; methotrexate group received oral administration of 2.0 mg/kg methotrexate twice a week; normal group and model group were given equal volumes of physiological saline by gavage once a day for 28 consecutive days. The general condition of each group of rats was observed, the degree of swelling in the right knee joint was measured, and the arthritis index was scored; HE was used to observe pathological changes in synovial tissue; immunofluorescence was used to detect the expressions of markers CD86 and CD206 in synovial macrophages; Real time PCR was used to detect the mRNA levels of IL-6, TNF-α, IL-10, and TGF-β in synovial tissue.Results:Duhuo Jisheng Decoction could significantly improve the mental state of the rats and reduced the swelling of the knee joints and the arthritis index ( P<0.01). Compared with the model group, the cartilage structure in the knees of rats in the Duhuo Jisheng Decoction group was more intact and clearer. The expression level of the M1 macrophage marker CD86 significantly decreased, and the expression level of the M2 macrophage marker CD206 significantly increased; the mRNA expressions of IL-6 and TNF-α in the knee joint synovial tissue were significantly reduced ( P<0.05), while IL-10 and TGF-β levels significantly increased ( P<0.05). Conclusion:Duhuo Jisheng Decoction may promote macrophage polarization towards M2 type, thereby achieving M1/M2 macrophage balance, alleviating inflammatory response in rheumatoid arthritis rats, and exerting therapeutic effects on rheumatoid arthritis.
