摘要
Observation of stilbene dropping pill and yiqi drug-containing serum influence mechanism of vascular smooth muscle proliferation， cell cycle and Cyclin D1 and CDK4Choose male SD rats were randomly divided into 2 groups， lavage qishen yiqi pill and the gastric saline group，extract the drug-containing serum and normal serum；To set the two groups of serum respectively different concentrations，concentration in different time by CCK8 detection effects on vascular smooth muscle cell proliferation， select best concentration and action time.Flow cytometry instrument and high-throughput screening detect serum medicated effect on vascular smooth muscle cell cycle；Western blot detect the drug-containing serum of cell cycle protein Cyclin D1 and CDK4 expression.Result is 5%， 10% medicated serum inhibits cell proliferation significantly higher than the normal serum concentrations of same within 24 h， 48 h.G1 phase cells 5% medicated serum group was obviously higher than that of 5% in normal group (P<005)， serum and cell proliferation index significantly less than 5% normal serum group (P<005)，At the same time， Cyclin D1 and CDK4 expression significantly less than 5% normal serum group (P<005).Conclusion serum of qishen yiqi pill can inhibit vascular smooth muscle cell proliferation， may be through inhibiting cell cycle protein Cyclin D1 and CDK4 expression， block the cell cycle G1 process is closely related to the role.
