摘要:


文题释义:

骨溶解:全关节置换术是临床上用来治疗骨关节炎、类风湿性关节炎等骨科相关疾病的常用临床手段,而在假体长期的使用过程中会摩擦产生微粒,可与关节假体周围细胞相互作用,引起成骨活动减弱和破骨活动增强,从而导致骨溶解,骨溶解也被称为关节置换的“隐形杀手”。
六味地黄丸:始载于宋代钱乙《小儿药证直诀》,是滋阴补肾的经典名方,且有文献报道其具有抗炎、调节骨参数、骨密度的药效特征,并被证实具有治疗骨质疏松的作用。


背景:目前已有大量研究发现六味地黄丸可用来治疗骨质疏松,而鲜有关于六味地黄丸对磨损微粒诱导的成骨细胞分化与矿化方面的相关研究。

目的:探讨不同浓度六味地黄丸含药血清对钛颗粒诱导的小鼠MC3T3-E1成骨细胞体外骨溶解模型的积极作用。
方法:大鼠口服六味地黄丸后提取含药血清,筛选六味地黄丸含药血清和钛颗粒对MC3T3-E1细胞活力影响的最佳浓度。将MC3T3-E1细胞为3组:空白组给予成骨分化培养;模型组给予钛颗粒(5 μg/mL)+成骨分化培养;加含药血清组给予钛颗粒(5 μg/mL)+六味地黄丸含药血清(分为10%,15%,20%剂量)共培养+成骨诱导。通过CCK-8法检测成骨细胞活力,碱性磷酸酶染色检测细胞碱性磷酸酶活性,通过硝酸银(Von Kossa)和茜素红染色检测细胞矿化情况,qRT-PCR检测成骨分化相关基因Runx-2、Osterix、Ocn、Axin、ALP和Opn的表达,Western blot检测Wnt/β-catenin信号通路β-catenin、p-GSK-3β、GSK-3β、Runx2和Osterix蛋白表达。

结果与结论:①六味地黄丸含药血清培养可以逆转钛颗粒诱导的MC3T3E-1细胞碱性磷酸酶活性的降低,增加MC3T3E-1细胞茜素红染色及钙化结节,增加MC3T3E-1细胞成骨相关基因的表达,同时提高Wnt/β-catenin信号通路相关蛋白的表达。②结果说明,六味地黄丸含药血清体外可以逆转钛颗粒对成骨细胞分化矿化的抑制作用,上调成骨相关基因的表达,其机制与调控Wnt/β-catenin信号通路相关,提示六味地黄丸有望成为防治人工关节无菌性松动的有效药物。

Abstract: BACKGROUND: At present, a large number of studies have found that Liuwei Dihuang Pill can be used to treat osteoporosis, but there are few related studies on the differentiation and mineralization of osteoblasts induced by wear particles using Liuwei Dihuang Pill.
OBJECTIVE: To investigate the positive effect of different concentrations of Liuwei Dihuang Pill-containing serum on titanium particle-induced mouse MC3T3-E1 osteoblast in vitro osteolysis model.  
METHODS: Drug-containing serum was extracted after oral administration of Liuwei Dihuang Pill. The best concentration of Liuwei Dihuang Pill-containing serum and titanium particles on the viability of MC3T3-E1 cells was screened. MC3T3-E1 cells were divided into three groups. The blank group was given osteoblastic differentiation culture. The model group was given titanium particles (5 μg/mL) ossification culture. The drug-containing serum group was given titanium particles (5 μg/mL) + Liuwei Dihuang Pill-containing serum (10%, 15% and 20% doses). Osteoblast viability was detected by CCK-8 assay. Cell alkaline phosphatase activity was detected by alkaline phosphatase staining. Cell mineralization was detected by silver nitrate (Von Kossa) and alizarin red staining. Expression levels of bone differentiation-related genes Runx-2, Osterix, Ocn, Axin, Alp, and Opn were detected by qRT-PCR. Wnt/β-catenin signaling pathways β-catenin, p-GSK-3β, GSK-3β, Runx2 and Osterix protein expression levels were detected by western blot assay.  
RESULTS AND CONCLUSION: (1) Liuwei Dihuang Pill-containing serum culture reversed the decrease in alkaline phosphatase activity of MC3T3E-1 cells induced by titanium particles, increased the alizarin red staining and calcification of MC3T3E-1 cells, increased the expression of osteogenesis-related genes in MC3T3E-1 cells, and increased the expression of proteins related to the Wnt/β-catenin signaling pathway. (2) These findings indicate that Liuwei Dihuang Pill-containing serum can reverse the inhibitory effect of titanium particles on the differentiation and mineralization of osteoblasts, upregulate the expression of osteogenesis-related genes, and its mechanism is related to the regulation of Wnt/β-catenin signaling pathway, suggesting that Liuwei Dihuang Pill is expected to become an effective drug for preventing aseptic loosening of artificial joints.
