摘要:

文题释义:

茶黄素-3,3’-双没食子酸酯:是一种红茶中多酚类衍生物,具有抗炎、抗氧化、抗衰老、抗癌等多种药理功能,已对多种炎症性疾病显示出治疗作用。
人工假体磨损颗粒:人工关节置换后由于假体与骨组织之间的长期磨损,出现大量微米级、纳米级的磨损颗粒并蓄积在假体周围,这种异物颗粒会引起假体与骨界面内细胞功能改变,诱导产生大量炎性细胞因子和趋化因子,导致假体周围微环境发生改变,破坏成骨细胞、破骨细胞、免疫细胞等局部细胞的平衡状态,最终假体与骨的整合失效,假体失去功能。

背景:茶黄素-3,3’-双没食子酸酯通过抑制破骨细胞形成在骨质疏松动物模型中显示出良好的治疗效果,但其对成骨细胞作用的研究还不多见。
目的:探讨茶黄素-3,3’-双没食子酸酯对人工假体周围骨溶解的作用。
方法:①体外实验:选取生长状态良好的MC3T3-E1细胞,分4组培养:对照组加入成骨诱导分化培养基,钛颗粒组加入钛颗粒+成骨诱导分化培养基,低剂量组加入钛颗粒+茶黄素-3,3’-双没食子酸酯(1 mg/L)+成骨诱导分化培养基,高剂量组加入钛颗粒+茶黄素-3,3’-双没食子酸酯(10 mg/L)+成骨诱导分化培养基。成骨诱导培养2周后,进行碱性磷酸酶染色;成骨诱导3周后,进行茜素红染色。②体内实验:将32只C57BL/6J小鼠按随机数字表法分4组,空白对照组不进行任何处理,模型组将无菌钛颗粒均匀置于颅骨表面建立骨溶解模型,低剂量组、高剂量组分别将1,10 mg/(kg·d)的茶黄素-3,3’-双没食子酸酯经腹腔注射至骨溶解模型小鼠体内。给药2周后,进行颅骨micro-CT扫描。

结果与结论:①体外实验:碱性磷酸酶与茜素红染色显示,钛颗粒可抑制MC3T3-E1细胞的碱性磷酸酶活性与矿化结节形成,茶黄素-3,3’-双没食子酸酯可抑制钛颗粒的作用,且具有剂量依赖性;②体内实验:micro-CT扫描显示,钛颗粒可引发颅骨周围骨溶解,高剂量茶黄素-3,3’-双没食子酸酯可抑制钛颗粒引起的骨溶解;③结果表明:茶黄素-3,3’-双没食子酸酯可促进成骨分化,抑制人工假体周围骨溶解。

Abstract: BACKGROUND: Theaflavin-3,3'-digallate has shown a good therapeutic effect in animal models of osteoporosis by inhibiting osteoclast formation, but there are few studies on osteogenesis.
OBJECTIVE: To investigate the effect of theaflavin-3,3'-digallate on periprosthetic osteolysis. 
METHODS: (1) In vitro test: The MC3T3-E1 cells with good growth status were selected and cultured in four groups. The control group was added with osteogenic differentiation medium; the titanium particle group was added with titanium particles + osteogenic differentiation medium; the low-dose group was added with titanium particles + theaflavin-3,3'-digallate (1 mg/L) + osteogenic differentiation medium; high-dose group was added with titanium particles + theaflavin-3,3'-digallate (10 mg/L) + osteogenic differentiation medium. After 2 weeks of osteogenic induction, alkaline phosphatase staining was performed; after 3 weeks of osteogenic induction, alizarin red staining was performed. (2) In vivo experiment: 32 C57BL/6J mice were randomly divided into 4 groups. The blank control group did not receive any treatment. In the model group, sterile titanium particles were evenly placed on the surface of the skull to establish an osteolysis model. The low-dose group and high-dose group were injected intraperitoneally with 1, 10 mg/(kg·d) theaflavin-3,3'-digallate into osteolysis model mice. The mouse skull was analyzed by micro-CT 2 weeks after operation.
RESULTS AND CONCLUSION: (1) In vitro experiments: alkaline phosphatase and alizarin red staining showed that titanium particles could inhibit alkaline phosphatase activity and mineralized nodule formation in MC3T3-E1 cells, and theaflavins-3,3'-bisgallate could inhibit the effect of titanium particles and was dose-dependent. (2) In vivo experiments: micro-CT scans showed that titanium particles could induce osteolysis around the skull, and high-dose theaflavin-3,3'-digallate could inhibit the osteolysis caused by titanium particles. (3) The results showed that theaflavin-3,3'-digallate could promote the osteogenic differentiation of MC3T3-E1 and inhibit periprosthetic osteolysis.

Key words: theaflavin-3,3'-digallate, titanium particle, osteogenic differentiation, periprosthetic osteolysis, prosthesis loosening
