Abstract:

BACKGROUND: Tougu Xiaotong capsule is the clinical prescription for the treatment of osteoarthritis in Fujian University of Traditional Chinese Medicine, and the previous studies mainly focus on effect to cartilage.
OBJECTIVE: To observe the effect of Tougu Xiaotong capsule on the proliferation and differentiation of osteoblasts as well as the expressions of bone remodeling correlated factors. 
METHODS: Rat osteoblast-like cell line ROS17/2.8 cells were incubated with Tougu Xiaotong capsule. The ROS17/2.8 cells were divided into blank control group and Tougu Xiaotong capsule groups with different concentrations. The cell proliferation was determined by methylthiazolyldiphenyl-tetrazolium bromide assay. Osteoblast differentiation biomarkers alkaline phosphatase activity, osteocalcin and bone mineralized nodules were measured with colorimetry, enzyme-linked immunosorbent assay and alizarin red staining, respectively. The real-time PCR and enzyme-linked immunosorbent assay were used to detect the expressions of bone remodeling factors osteoprotegerin/receptor activator of nuclear factor κB ligand.
RESULTS AND CONCLUSION: Compared with the control group, the Tougu Xiaotong capsule with the concentration of 0.25-2 g/L could significantly promote the ROS17/2.8 cell proliferation (P < 0.05), up-regulate the alkaline phosphatase activity, osteocalcin expression level and mineralized nodules area, and increase the percentage of bone remodeling factors osteoprotegerin/receptor activator of nuclear factor κB ligand (P < 0.05). The mechanism of Tougu Xiaotong capsule protecting osteoarthritis may partly result from the regulation of proliferation and differentiation of osteoblasts and bone remodeling.
