摘要:

背景:接骨七厘片是促进骨折愈合、临床疗效较好的复方中药,但其作用机制尚不十分清楚。

目的:观察接骨七厘片药物溶液对成骨细胞增殖和钙盐沉积能力的影响。
方法:以体外培养的MC3T3-E1成骨细胞为研究对象。①常规培养24 h更换无血清DMEM培养液,饥饿培养24 h同步化细胞周期,弃去培养液,实验组每孔加入100 μL含接骨七里片药物溶液的DMEM完全培养基,对照组加入DMEM完全培养基,于培养24 h和48 h使用MTS一步法检测细胞增殖活力。②以1×105密度接种MC3T3-E1细胞于96孔板,培养4 h更换成骨诱导培养液,诱导21 d进行茜素红染色观察MC3T3-E1细胞的钙盐沉积能力,对照组细胞不进行成骨诱导。
结果与结论:在培养24 h和48 h,接骨七厘片药物实验组细胞增殖程度均较对照组上调(P < 0.05);成骨诱导21 d后,茜素红染色发现接骨七厘片药物实验组钙盐结节生成明显多于对照组(P < 0.01)。以上结果表明接骨七厘片药物溶液能够明显促进成骨细胞增殖和钙盐沉积能力。

Abstract:

BACKGROUND: Jiegu Qili Tablet is a compound Chinese medicine which can promote fracture healing, but its mechanism is still unclear.

OBJECTIVE: To observe the effects of Jiegu Qili Tablet on the proliferation and mineralization of MC-3T3 cells.
METHODS: MC-3T3 cells cultured in vitro were selected. (1) After 24 hours of routine culture, cells were cultured in serum-free DMEM for another 24 hours to synchronize cell cycles. Then, the culture solution was removed, and cells were cultured in DMEM complete medium with (experimental group) or without (control group) Jiegu Qili Tablet solution. At 24 and 48 hours of culture, MTS assay was used to detect the proliferative ability of cells. (2) In the experimental group, MC3T3-E1 cells at a density of 1×105 were inoculated into 96-well plates, and after 4 hours of culture, cells were cultured in an osteogenic induction medium. After 21 days of osteogenic induction, the mineralization of MC3T3-E1 cells was examined using alizarin red S staining. Cells in the control groups were treated without osteogenic induction.
RESULTS AND CONCLUSION: Compared with the control group, the cell proliferation rate was up-regulated in the experimental group at 24 and 48 hours after culture (P < 0.05), and the number of calcium nodules was also larger in the experimental group at 21 days after osteogenic induction (P < 0.01). These findings indicate that Jiegu Qili Tablet solution can up-regulate the proliferation and mineralization of MC-3T3 cells.
