文题释义:
富血小板血浆:是自体全血经离心后得到的血小板浓缩物。富血小板血浆中含有大量生长因子及蛋白质。1993年Hood等首先提出富血小板血浆概念,并发现富血小板血浆含有丰富的血小板,其数目比全血中数目高3倍以上。血小板中含有大量的生长因子,如血小板衍生生长因子,转化生长因子β,类胰岛素生长因子,表皮生长因子,血管内皮生长因子等。目前,在口腔科及骨科领域,富血小板血浆研究很热门。
富血小板血浆的制备:为新鲜血液经低速离心制备而成。将采集的全血在室温下于4-6 h内以27.5-  37.5 r/min低速离心15-20 min(或1 220 r/min离心5 min),使红细胞、白细胞基本下沉,由于血小板密度轻,大部分保留在上层血浆中,分离出上层血浆,即为富血小板血浆,可获得全血中70%以上血小板。
摘要
背景:
富血小板血浆富含多种生长因子,可以促进某些组织的再生。
目的:提取兔自体富血小板血浆,将其注射在牵拉间隙内,通过影像学及组织学评价富血小板血浆对兔牵拉成骨矿化过程的作用。
方法:32只成年日本大耳白兔,分为4组,每组8只。取兔后肢行胫骨上1/3线锯截骨,制作肢体延长动物模型,分别在建模后5,15,25 d局部注射富血小板血浆500 μL 1次,对照组只进行肢体延长,不注射富血小板血浆,术侧肢体完成1 cm胫骨延长。在建模后第35天,处死实验动物,对牵拉新生骨痂进行取材和苏木精-伊红染色,并拍摄兔胫骨正位X射线片。
结果与结论:①按照Lane-SandhuX线评价标准评分:建模后15 d注射组、建模后25 d注射组评分明显优于对照组和建模后5 d注射组;②按照Lane-Sandhuz组织学评价标准评分:建模后15 d注射组、建模后25 d注射组组织学评分明显优于对照组和建模后5 d注射组(P < 0.05),而建模后25 d注射组的组织学平均评分最高;③结果说明,在兔肢体延长的过程中,提取自体富血小板血浆能够促进骨的矿化成熟,并且在稳定期的中段局部注射,作用最强。

Abstract:

BACKGROUND: The platelet-rich plasma contains various growth factors that could enhance the regeneration of certain tissues.
OBJECTIVE: To observe the effect of platelet-rich plasma on the mineralization process during distraction osteogenesis in rabbits.
METHODS: Thirty-two adult Japanese white rabbits were randomly divided into four groups (n=8 per group). The upper 1/3 tibial osteotomy at the posterior limb was performed in all rabbits, and the 1 cm limb lengthening models were prepared, followed by the local injection of 500 μL platelet-rich plasma at 5, 15 and 25 days. The controls received no treatment. At 37 days after modeling, the rabbits were killed and newly formed callus was removed to undergo hematoxylin-eosin staining, and the frontal X-ray film of tibia was obtained.
RESULTS AND CONCLUSION: Lane-Sandhu radiographic scoring showed that the scores in the injection groups at 15 and 25 days after modeling were obviously better than those in the control group and the injection at 5 days after modeling. Lane-Sandhu histological scoring revealed that the scores in the injected groups at 15 and 25 days after modeling were significantly higher than those in the control group and group at 5 days after modeling (P < 0.05), which highest at 25 days. These results suggest that local injection of platelet-rich plasma can promote bone mineralization during distraction osteogenesis effectively, especially in the middle period of distraction osteogenesis.
