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,其仍使用富血小板纤维蛋白离心机,通过调整转速及时间来获得不同的细胞分布和更多的生长因子,以及更佳的软硬组织愈合效果,目前国内外对其研究报道较少。
PRF:即富血小板纤维蛋白,是platelet-rich fibrin的简写。在2001年由法国科学家Choukroun等人发现,是继富血小板血浆后第二代血小板浓缩制品,被定义为一个自体的白细胞和富血小板纤维生物材料。


背景:前期实验验证了富血小板纤维蛋白具有成骨的效果,并且选定了人与兔改良型富血小板纤维蛋白膜结构最相似时的转速和离心时间。
目的:观察改良型富血小板纤维蛋白在诱导成骨中的组织学变化。
方法:随机将30只日本大耳兔分为2组各15只,在兔颅顶骨制造圆形全层骨缺损来构建动物模型,改良型富血小板纤维蛋白组填入改良型富血小板纤维蛋白膜,空白组不填任何材料,于建模后当天、2周、4周、8周、12周处死动物,大体观察造模区成骨情况,苏木精-伊红染色、masson三色染色、免疫组织化学观察造模区组织学变化。
结果与结论:①空白组骨缺损在实验结束时不能自行愈合;②建模后当天、4周、8周、12周2组标本的大体观察、组织学检查,均显示改良型富血小板纤维蛋白组的成骨速度、量及成熟度,皆明显优于空白组,差异具有统计学意义;③结果说明,制备的骨缺损实验期内不能自行愈合,符合临界性骨缺损的标准;改良型富血小板纤维蛋白能促进新骨形成,随着时间的延长,成骨数量更多,质量更佳;改良型富血小板纤维蛋白促使破骨细胞与成骨细胞协同作用,促进新骨生成。

Abstract:

BACKGROUND: Previous studies have proved platelet-rich fibrin (PRF) with osteoinduction ability, and the centrifugal speed and time to prepare rabbit advanced PRF (A-PRF) with the most similar structure to that of human PRF have been determined.
OBJECTIVE: To observe the histological changes during A-PRF-induced osteogenesis.
METHODS: Thirty Japanese white rabbits were randomly divided into A-PRF and blank control groups (n=15 per group). The full-thickness defect models were established on the rabbit parietal bone, followed by implanted with A-PRF or nothing, respectively. The model rabbits were killed immediately, at 2, 4, 8 and 12 weeks after modeling, to grossly observe the bone formation, and the histological changes in the defect region were observed through hematoxylin-eosin staining, Masson staining and immunohistochemistry.
RESULTS AND CONCLUSION: Unhealed defects were observed in the blank control group. Gross and histological observations showed that the speed, amount and maturity of bone formation in the A-PRF group were significantly better than those in the blank control group immediately, 4, 8 and 12 weeks after modeling (P < 0.05). Our findings suggest that the rabbit skull bone defect is successfully established. A-PRF can induce osteogenesis, and more mature newly born bones appear with time. Additionally, osteoclasts can act with osteoblasts synergically under the A-PRF induction to promote the bone formation.
