文题释义:
富血小板纤维蛋白:是一种采集自体血液,一次离心既可,无需对血液做任何生化处理所形成的三维网状结构,富含多种生长因子,能促进骨和软组织的形成的一种自体生物材料。

骨诱导:是指来自植床周边宿主结缔组织中的可诱导成骨前体细胞,在诱导因子的作用下可被诱导定向产生骨原细胞,经成骨细胞形成新骨(骨形态发生蛋白的参与)。

 

背景:作者在前期的实验中已证实富血小板纤维蛋白具有成骨性,并在微观结构和生物力学等方面进行了初步研究,但是对组织学上的研究较少。
目的:对比观察富血小板纤维蛋白、Bio-Oss、自体骨3种不同骨替代材料植入后的组织学变化,分析富血小板纤维蛋白修复骨缺损的特点和优势。
方法:12只beagle犬,参照文献方法建立犬双侧股骨髁左右各3个实验性临界性骨缺损动物模型。在3个骨缺损区随机分别填入自体富血小板纤维蛋白组,自体骨+胶原膜(自体骨组),Bio-Oss+胶原膜组(Bio-Oss组) 。在植入后3,6,8和12个月分别处死3只实验犬,术区取材后进行组织学染色观察。另外1只实验动物按照上述方法制造临界性骨缺损模型后,不植入任何材料,标记为空白组。
结果与结论:植入后3,6,8和12个月时,3种骨移植材料的新骨生成速度、生成量差异均有显著性意义。3种材料均能诱导成骨,但是成骨能力各不相同:富血小板纤维蛋白组在3个月和6个月时成骨效果更优,且形成的新骨更接近生理状态;自体骨在植入后3个月和6个月更多以骨坏死为主,8个月后成骨效果可,12个月后基本接近生理状态;Bio-Oss组成骨效果与富血小板纤维蛋白组类似,在12个月时仍可见Bio-Oss残留颗粒;空白组在术后3个月时未见明显新骨形成,说明该实验动物临界性骨缺损模型建立成功。实验结果显示富血小板纤维蛋白具有较好的诱导新骨形成的能力,且新骨形成所需时间更短,质量佳。

Abstract:

BACKGROUND: In previous experiments, we have confirmed that platelet rich fibrin has the ability of osteoinduction, and have conducted a preliminary study on its microstructure and biomechanics. However, little is reported on its histology research.
OBJECTIVE: To compare the histological changes after implanting platelet-rich fibrin, Bio-Oss and autologous bone and to analyze the pros and cons of platelet-rich fibrin implantation for repair of bone defects.
METHODS: As previously reported, animal models of critical bone defects were established respectively on the bilateral femoral condyles of 12 beagle dogs. Then, platelet-rich fibrin, Bio-Oss+collagen membrane (Bio-Oss group) and autologous bone (autologous bone group)+collagen membrane were respectively implanted. At 3, 6, 8 and 12 months, one experimental dog from each group was killed, respectively, and histological observation was performed. Another beagle dog as blank control was enrolled to establish the animal model of critical bone defects, with no implantation.
RESULTS AND CONCLUSION: At 3, 6, 8 and 12 months after implantation, there were significant differences in the new bone formation speed and amount between the platelet-rich fibrin group, Bio-Oss group and autologous bone group. These three kinds of bone grafts all had osteoinductive ability to different extents. In the platelet-rich fibrin group, the osteogenic effects were better at 3 and 6 months, and the new bone was similar to natural one; in the autologuos bone group, bone necrosis was noticeable at 3 and 6 months, but the osteogenic effects became better at 8 months, and the new bone was similar to natural one at 12 months; in the Bio-oss group, the osteogenic effects were similar to those in the platelet-rich fibrin group, but the residual of Bio-oss was visible at 12 months; in the blank control group, no bone formed at 3 months, indicating the animal model of critical bone defects was made successfully. In brief, the platelet-rich fibrin has good osteoinductive ability, with shorter time and better quality.
