Objective To investigate the effect of calcitonin gene-related peptide ( CGRP ) in inducing os-teogenic differentiation of rat precartilaginous stem cells in vitro and the underlying mechanisms. Methods Rat pre-cartilaginous stem cells ( PSCs) were cultured in complete osteogenesis medium containing DMEM/F-12 medium and different concentrations (0, 10-8,10-9,10-10mol/L) of CGRP, the morphology changes of PSCs were observed. The proliferation of PSCs was examined at different time points by CCK-8. All the PSCs were then randomly assigned to an experimental group and a control group. The PSCs in the experimental group were cultured in complete osteogenesis medium with 10-10 mol/L CGRP , while the control group cultured merely in complete osteogenesis medium was re-ceived no special intervention. Both groups were stained by Alizarin Red and the expression of alkaline phosphatase (ALP) was detected. The osteogenic genes (RUNX2,OPN and BGP) were measured by use of RT-PCR. The activa-tion of Wnt/β-catenin signaling pathway was tested by using Western blotting to evaluate the effect of CGRP . Results Compared to the control group ( the concentration of CGRP was 0 mol/L) , the concentration of ALP was significantly higher in the experimental group, calcium deposition was significantly more obvious, and the expression of the osteogenic genes such as RUNX2,OPN and BGP as well as theβ-catenin protein expression were up-regulated significantly. However, CGRP had no effect on cell proliferation. Conclusion CGRP activated Wnt/β-catenin sig-nal pathway and induced osteogenic differentiation of precartilaginous stem cells.

Objective To study the therapeutic effects and related mechanism of Tongmai Yizhi granules on vascular dementia in rats. Methods Bilateral carotid artery ligation was used to establish rat model of vascular dementia (VD). The rats were randomly divided into 6 groups: sham operated,the model control,piracetam (0. 375 g·kg-1 ·d-1 ) as positive con-trol,low dose (2. 5 g·kg-1 ·d-1 ),middle dose(5. 0 g·kg-1 ·d-1 ),and high dose (10. 0 g·kg-1 ·d-1 ) of Tongmai Yizhi granules. Each group was intragastrically administered with 10 mL·kg-1 of corresponding medications for 31 days after the VD model was established. The sham group was given with 0. 9% NaCl solution. Y-electric maze was used to test the learning and memory function of rats at the second and fourth weeks. On the day 32,hippocampal tissues were collected for pathological analy-sis by microscope. The activities of SOD and content of MDA in serum and tissue homogenate were tested. Results Compared with model control group,each dose of Tongmai Yizhi granules obviously shortened the incubation period of VD rats in electric maze test,and accuracy of learning and memory was improved (P<0. 05 or P<0. 01). The activity of SOD was decreased,and the content of MDA was increased after treatment with Tongmai Yizhi granules (P < 0. 01). Hippocampal neuronal cells were disar-ranged,and the number of cone cells was decreased significantly in the model control group. In contrast,the necrosis and degener-ation of hippocampal neurons were alleviated in all Tongmai Yizhi treatment groups. Conclusion Tongmai Yizhi granule can apparently improve learning and memory function of VD rats. It can also improve the activity of SOD and reduce the content of MDA in serum and hippocampus,effectively remove free radicals,and alleviate the injury of hippocampal pyramidal cells.
