目的 探讨丹参注射液对缺氧培养大鼠神经干细胞的凋亡及Caspase-3活性的影响,以进一步明确丹参注射液神经保护作用的分子机制.方法 体外培养新生大鼠海马神经干细胞,将其分为正常对照组,缺氧培养组及丹参注射液处理组.Hoechst染色后荧光显微镜下观察并计算细胞凋亡率:比色法检测各组细胞Caspase-3的相对活性.结果 缺氧培养大鼠神经干细胞的细胞凋亡率(30.12%±2.09%)及Caspase-3活性(3.85±0.41)均较正常对照组(2.75%±0.28%,1.16±0.07)明显升高,差异有统计学意义(P<0.05);施加丹参注射液后,大鼠神经干细胞的细胞凋亡率(9.16%±1.34%)和Caspase-3活性(1.50±0.09)均较缺氧培养组明显下降,差异有统计学意义(P<0.05).结论丹参注射液可对抗缺氧损伤所致的神经干细胞凋亡,从而起到神经保护作用.

Objective To explore the effects of salvia miltiorrhizae (SM) injection on the apoptosis of cultured rat neuronal stem cells induced by hypoxia and the activity of Caspase-3, in order to provide the further evidence for the molecular mechanism of neuroprotection of SM injection. Methods The neuronal stem cells from neonatal rat hippocampus were cultured and divided randomly into normal control group, hypoxia group and SM treatment group. After Hoechst staining, the apoptotic morphological change and apoptosis percentage were observed under fluorescence microscope. The activities of Caspase-3 in the 3 groups were evaluated by the colorimetric assay. Results Compared with normal control group [(2.75±0.28)%, 1.16±0.07], the percentage of apoptosis and the activity of Caspase-3 were increased significantly in neuronal stem cells cultured in hypoxia [(30.12%±2.09)%,3.85±0.41, P<0.05). Application of SM injection reduced markedly the percentage of apoptosis and the activity of Caspase-3 of the neuronal stem cells cultured in hypoxia [(9.16±1.34)%, 1.50±0.09, P<0.05].Conclusion SM injection can depress the apoptosis of the rat neuronal stem cells induced by hypoxia,so as to exert the neuroprotection.
