ABSTRACT
<p><b>OBJECTIVE</b>To observe effects of serum Bushen Huoxue prescription(Chinese characters) on classic Wnt/β-catenin signaling pathways of osteoblasts, and explore mechanism of Bushen Huoxue prescription (Chinese characters) for preventing osteoporosis.</p><p><b>METHODS</b>Twenty health female rats were randomly divided into two groups, including Bushen Huoxue (Chinese characters) group and saline group,10 in each group. Bushen Huoxue (Chinese characters) group and Saline group were gavaged Bushen Huoxue and saline every day for 1 week. Bushenhuoxue containing serum and saline containing serum were got according to methods of serum preparation of drug-containing. The osteoblasts was cultured with neonatal rat skull according to Enzyme Consumer Law, and was identified by Wright-Giemsa staining (R-J) and alkaline phosphatase staining (ALP). The third generation of osteoblasts was divided into three groups, including saline group, normal group,Bushen Huoxue (Chinese characters) group. Each group were added to 15% appropriate medium. ALP activity of osteoblasts and osteoblasts proliferation rate were tested, mineralized nodules were observed, the expression of β-catenin, Runx2, Osx mRNA of osteoblasts were tested by RT-PCR.</p><p><b>RESULTS</b>There was blue granules in cytoplasm, cell nucleus was flint with 1 to 3 nucleoli showed by R-J staining, morphology of osteoblasts were cultured. ALP staining showed cytoplasm with purple granules, the results showed that the cultured cell was osteoblasts. The content of ALP in Bushen Huoxue (Chinese characters)group was (6.272±0.131) ,appreciation rate was (0.81? 0.172), and could significantly improve differentiation and proliferation activity of osteoblasts compared with Saline group (P< 0.01). There were four different size orange nodules, the Maximun nodule was 1.0 x 1.0 cm in Bushen Huoxue (Chinese characters) group after Alizarin red staining, the results showed Bushen Huoxue (Chinese characters)group could obviously improve mineralization of osteoblasts. The expression of mRNA of β-catenin, Runx2 and Osx in Bushen Huoxue (Chinese characters)group were (1.782±0.944), (1.935±0.994) and (1.610±0.811) by RT-PCR,it was significantly increased compared with saline group (P<0.01), but there was no difference between Bushen Huoxue (Chinese characters)group and normal group (P>0.05).</p><p><b>CONCLUSION</b>Bushen Huoxue (Chinese characters)group could obviously promote differentiation, proliferation and mineralization of osteoblasts through activation of Wnt, β-catenin signaling pathway. It suggested that the mechanism of action of Bushen Huoxue (O'f f Il.t)particle clould prevent osteoporosis through the activation of Wnt, β-catenin signaling pathway.</p>
