文题释义:
改良型富血小板纤维蛋白
:是一种在富血小板纤维蛋白基础上进行改进的自体来源血液材料,条索较为粗大,白细胞及单能干细胞数目较富血小板纤维蛋白增加,特别是嗜中性粒细胞增多,可释放更多凝血因子及中性粒细胞趋化因子等,更有利于预防感染;在改良型富血小板纤维蛋白降解过程中,血小板被激活,其α脱颗粒可释放多种生长因子,如骨形成蛋白、血小板衍生因子AB、转化生长因子β、胰岛素增长因子、白细胞介素4等,促进软组织愈合和骨缺损的修复。
骨整合:是指正常的改建骨与种植体表面形成稳定的直接接触,种植体承受的负载通过直接接触周围骨组织的途径均匀分散到骨组织中。


背景:前期兔临界性骨缺损修复实验显示,β-磷酸三钙与改良型富血小板纤维蛋白复合材料可诱导新生骨形成,促进骨组织的修复,效果优于单独使用β-磷酸三钙或改良型富血小板纤维蛋白。
目的:进一步探索β-磷酸三钙与改良型富血小板纤维蛋白复合材料引导的新生骨与种植体骨整合性能。
方法:取18只日本大耳兔(成都达硕生物科技有限公司提供),建立双侧股骨髁部骨缺损模型(直径6 mm、深度10 mm),随机分3组:β-磷酸三钙组将β-磷酸三钙材料填入骨缺损处,改良型富血小板纤维蛋白组将改良型富血小板纤维蛋白填入骨缺损处,复合组将质量比为1∶1的β-磷酸三钙与改良型富血小板纤维蛋白混匀,填入骨缺损处;材料植入后3个月,植入DIO种植体,种植体植入后第4,12周获取带种植体的新生骨标本,进行Micro-CT及种植体推出实验,检测骨结合界面质量与推出最大荷载值。
结果与结论:①Micro-CT检测显示,随着时间的延长,各组新生骨量逐渐增加,并且复合组植入后第4,12周的新生骨量多于β-磷酸三钙组、改良型富血小板纤维蛋白组(P < 0.05);②种植体推出实验显示,随着时间的延长,各组最大推出力增加,并且复合组植入后第4,12周的最大推出力高于β-磷酸三钙组、改良型富血小板纤维蛋白组(P < 0.05);③结果表明相对于单独应用,β-磷酸三钙与改良型富血小板纤维蛋白复合材料可优化新骨与种植体的结合。

Abstract:

BACKGROUND: Preliminary studies have shown that β-tricalcium phosphate loaded with advanced platelet-rich fibrin can induce bone formation and promote bone repair, which is better than β-tricalcium phosphate or advanced platelet-rich fibrin alone. 

OBJECTIVE: To further explore the osseointegration properties of newly formed bone induced by β-tricalcium phosphate loaded with advanced platelet-rich fibrin.
METHODS: Eighteen Japanese rabbits provided by Chengdu Dashuo Biotechnology Co., Ltd. in China were used for establishing the bilateral femoral condyle defect models (6 mm in diameter and 10 mm in depth). There were three groups implanted with advanced platelet-rich fibrin, β-tricalcium phosphate or β-tricalcium phosphate loaded with advanced platelet-rich fibrin (mass ratio 1:1) composite, respectively. At 3 months after implantation, the DIO implant was implanted. The newly bone samples with the implants were then obtained to perform micro-CT and push-out test of implants at 4 and 12 weeks. The osteogenic properties and maximum load of the implant-bone interface were detected.

RESULTS AND CONCLUSION: Micro-CT findings revealed that the amount of newly formed bone in each group was increased with time, which was significantly higher in the combined group than the other two groups at 4 and 12 weeks after implantation (P < 0.05). Results from the push-out test of implants showed that as time went on, the maximum push strength of each group was increased, which was significantly higher in the combined group than in the other two groups at 4 and 12 weeks after implantation (P < 0.05). In summary, the combined strength of the implant-bone interface of β-tricalcium phosphate loaded with advanced platelet-rich fibrin is superior to that of advanced platelet-rich fibrin or β-tricalcium phosphate.
