文题释义:
补肾活血方:
课题组前期研究发现,新疆地区维、汉妇女绝经后骨质疏松症中医证型分布规律以肾虚血瘀型为最多见,根据“肾藏精,血瘀论”拟定补肾活血方,用于治疗骨质疏松症取得良好疗效,但其作用机制尚不清楚。该方由鹿角胶、补骨脂、淫羊藿、丹参、黄芪、熟地黄、白芍等中药组成,作者采用水提的方法获得补肾活血方,其提纯的药物所含生药量为1.43 g/mL。
细胞毒性:是由细胞或化学物质引起的单纯细胞杀伤事件,不依赖于凋亡或坏死的细胞死亡机制。细胞毒性检测主要是根据细胞膜通透性发生改变来进行,常用以下2种方法:MTT法及CCK-8法。CCK-8法对细胞毒性小,可以多次测定选取最佳测定时间,与MTT方法相比线性范围更广。

 

摘要
背景:
目前补肾活血方干预骨髓间充质干细胞增殖分化的实验中,其最佳影响质量浓度是多少,尚不明确。
目的:探讨补肾活血方提取物诱导骨髓间充质干细胞增殖分化的最佳质量浓度和最佳时间。
方法:采用贴壁筛选培养法分离纯化SD大鼠骨髓间充质干细胞,取第3代细胞用于实验。将补肾活血方提取物按质量浓度梯度(0,10,20,40,100,120,150,200,300,400,500,600 mg/L)干预第3代骨髓间充质干细胞,诱导时间分别为1,3,5,7 d。荧光倒置显微镜观察补肾活血方提取物干预后骨髓间充质干细胞的生长情况。用CCK-8法检测不同质量浓度补肾活血方提取物对骨髓间充质干细胞的毒性,筛选最佳药物质量浓度和作用时间。
结果与结论:与0 mg/L组比较,第5,7天时,100,120,150 mg/L补肾活血方提取物可促进骨髓间充质干细胞增殖(P < 0.05);在第7天时,150 mg/L补肾活血方提取物促增殖作用最强(P < 0.01);药物质量浓度在150-200 mg/L时,增殖率下降明显;随着实验时间的延长,大于200 mg/L时,骨髓间充质干细胞增殖不明显。

Abstract:

BACKGROUND: It is unclear what is the optimal concentration of Bushen Huoxue Recipe to promote the proliferation and differentiation of bone marrow mesenchymal stem cells.
OBJECTIVE: To investigate the optimal concentration and induction time of Bushen Huoxue Recipe extract to induce the proliferation and differentiation of bone marrow mesenchymal stem cells.
METHODS: Bone marrow mesenchymal stem cells of Sprague-Dawley rats were isolated and purified by adherent screening culture. Then, the bone marrow mesenchymal stem cells of 3rd generation were cultured with the extracts of Bushen Huoxue Recipe at different concentration (0, 10, 20, 40, 100, 120, 150, 200, 300, 400, 500 and 600 mg/L). The induction time was 1, 3, 5 and 7 days, respectively. The growth of bone marrow mesenchymal stem cells induced by Bushen Huoxue Recipe extracts was observed by fluorescent inverted microscope. The toxicity of different concentration solutions to bone marrow mesenchymal stem cells was detected by cell counting kit-8 for screening the optimal drug concentration and induction time.
RESULTS AND CONCLUSION: Compared with the 0 mg/L group, 100, 120 and 150 mg/L extracts from Bushen Huoxue Recipe significantly promoted the proliferation of bone marrow mesenchymal stem cells at the 5th and 7th days (P < 0.05). The 150 mg/L Bushen Huoxue Recipe extract showed the strongest proliferative effect (P < 0.01), while the proliferation rate decreased significantly, when the mass concentration of Bushen Huoxue Recipe extract was 150-200 mg/L. With the extension of the induction time, the proliferation of bone marrow mesenchymal stem cells showed no obvious changes after intervention with Bushen Huoxue Recipe at a concentration of more than 200 mg/L.
