ABSTRACT
<p><b>OBJECTIVES</b>To study the effect of Wenhua Juanbi Recipe (, WJR) on expression of receptor activator of nuclear factor kappa B ligand (RANKL), osteoprotegerin (OPG), and tumor necrosis factor receptor superfamily member 14 (TNFRSF14, also known as LIGHT) in rats with collagen-induced arthritis (CIA).</p><p><b>METHODS</b>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 sacrifificed 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.</p><p><b>RESULTS</b>Compared with the normal group, toe swelling degree was signifificantly increased in the model group (P<0.01). After treatment, toe swelling degree decreased signifificantly 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 signifificantly increased and OPG signifificantly decreased in peripheral blood and synovium of the model group (P<0.01). Conversely, RANKL and LIGHT expression were signifificantly 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.</p><p><b>CONCLUSION</b>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.</p>
