文题释义:
葛根素:是从豆科植物野葛根中提取分离出的一种异黄酮类化合物,属植物雌激素的一种,包括葛根素、大豆甙元、大豆甙、甲氧基葛根素、染料木素、刺芒柄花素等,葛根素是葛根黄酮中含量最多的有效成分。研究发现其具有抗炎、抗氧化、抗骨质疏松、降糖、抗癌等多种功能活性。近年来不少学者证实其具有促进成骨细胞增殖和分化以及矿化的特性。
β-磷酸三钙:主要由钙、磷组成,其成分与骨基质的无机成分Ca10(PO4)2相似,具有良好的生物相容性。学者们已经证实了,β-磷酸三钙能被机体所吸收,无炎症或排斥反应,不产生局部或全身性毒性反应。研究显示β-磷酸三钙具有良好的骨传导性,与种子细胞或生物调节因子联合应用时,原位或异位成骨效果理想。
摘要
背景
:葛根素提取自豆科植物野葛的根部,根据其化学结构可归类为异黄酮类化合物,据报道异黄酮具有促进成骨细胞增殖分化功能。
目的:观察不同浓度葛根素对β-磷酸三钙成骨细胞复合物的影响,探讨葛根素对体内成骨作用的影响。
方法:①取新生兔颅盖骨进行成骨细胞培养,应用碱性磷酸酶试剂盒及茜素红染色方法观察不同浓度葛根素对体外培养成骨细胞碱性磷酸酶活性及矿化结节形成影响;②选促进成骨细胞活性最佳浓度葛根素组作为A组,无葛根素培养的细胞为B组,2组培养的成骨细胞复合于β-磷酸三钙,使用MTT法检测支架材料中成骨细胞活性;③将2组细胞支架复合物植入兔背阔肌中,通过组织学方法分析葛根素在体内对新骨生成的作用。
结果与结论:葛根素可提高成骨细胞碱性磷酸酶活性及矿化结节形成数量,1×10-6 mol/L葛根素能明显提高支架材料中成骨细胞活性,将1×10-6 mol/L葛根素干预的细胞制成的细胞支架复合物植入兔背阔肌后,新骨生成量明显增加。提示葛根素具有促进 β-磷酸三钙成骨细胞复合物体内新骨生成作用,可作为促进成骨治疗的选择药物。

Abstract:

BACKGROUND: Puerarin is the major bioactive ingredient isolated from the root of the Pueraria lobata (Willd.) Ohwi, which is a kind of isoflavones. Isoflavones has been shown to promote the proliferation and differentiation of osteoblasts.
OBJECTIVE: To observe the effect of puerarin at different concentrations on the osteogenic activity of β-tertiary calcium phosphate (β-TCP) complex, and to investigate the effect of puerarin on osteogenesis in vivo.
METHODS: Osteoblasts isolated from calvarial of newborn rabbits were cultured in vitro with different concentrations of puerarin. The alkaline phosphotase activity and mineral node formation were determined by alkaline phosphatase kit and alizarin red staining. The osteoblasts cultured with the optimal concentration of puerarin (group A) or without puerarin (group B) were seeded on β-TCP, respectively. Osteoblast activity was determined using MTT assay. Scaffold complexes in each group were implanted into the rabbit dorsal muscles. Osteogenesis was analyzed by histological analysis.
RESULTS AND CONCLUSION: The alkaline phosphatase activity and mineral nodules were significantly increased in osteoblasts cultured with puerarin, and 1×10-6 mol/L puerarin could significantly incresase increase the osteoblast activity in the scaffold. After the β-TCP composite scaffolds cultured with 1×10-6 mol/L puerarin were implanted into the rabbit dorsal muscles, the newly formed bone was significantly increased. In summary, puerarin enhances the osteogenic effect of β-TCP osteoblast complex in vivo, which can be used to promote osteogenesis.
