Methods： CIA rats were generated by subcutaneous injection of bovine collagen type-Ⅱ at the tail base. Sixty CIA rats were randomly assigned（10 animals/group） to： model, methotrexate（MTX）-treated（0.78 mg/kg body weight）, and WJR-treated（22.9 g/kg） groups. Healthy normal rats（n=10） were used as the normal control. Treatments or saline were administered once daily by oral gavage. Rats were sacrificed at day 28 post-treatment and knee synovium and peripheral blood serum were collected. Toe swelling degree and expression of RANKL, OPG, and LIGHT were determined by Western blot and immunohistochemistry. Results： Compared with the normal group, toe swelling degree was significantly increased in the model group（P〈0.01）. After treatment, toe swelling degree decreased significantly in the WJR and MTX groups compared with the model group（P〈0.01）. Compared with the normal group, expression of RANKL and LIGHT were significantly increased and OPG significantly decreased in peripheral blood and synovium of the model group（P〈0.01）. Conversely, RANKL and LIGHT expression were significantly reduced and OPG increased in the WJR and MTX groups compared with the model group（P〈0.01）. No statistically significant difference existed between WJR and MTX groups. Conclusion： WJR likely acts by reducing RANKL expression and increasing OPG expression, thus inhibiting RANKL/RANK interaction and reducing LIGHT expression, thereby inhibiting osteoclast formation/activation to block bone erosion.展开更多
