Abstract:
Objective To explore the effect of Zhengu Pills ( a kidney-tonifying and blood-activating Chinese medicine) and Guci Fengshi Pills ( a dampness-dispelling and blood-activating Chinese medicine) on bone remodeling of cell model in vitro. Methods MC3T3-E1 and RAW264.7 cells were differentiated into osteoblasts ( OB) and osteoclasts ( OC) after stimulated by different inductive agents respectively, and then OB and OC were co-cultured. Immunocytochemical staining was applied to identify the construction of co-cultured OB and OC system. The serum containing corresponding medicine was prepared after the rats were given intragastric administration of Diacerein, Zhengu Pills and Guci Fengshi Pills. And then the obtained serum was used for treatment of co-cultured cells separately. At the end of experiment, Western blotting and real-time polymerase chain reaction (PCR) tests were carried out. Results The osteoprotegerin (OPG) expression was increased and gene expression of glycoprotein 130 (gp130) was decreased in co-cultured cells after treatment with the serum containing Zhengu Pills and Guci Fengshi Pills ( P<0.05) . Conclusion Zhengu Pills and Guci Fengshi Pills have therapeutic effects on osteoarthritis ( OA) by inhibiting the bone resorption function of OC by the down-regulation of gp130 and by enhancing bone formation and increasing the bone density through recombinant murine’s RANK ligand (RANKL) -RANK-OPG system.
