富血小板血浆的作用机制及其骨科临床应用进展

富血小板血浆(PRP)是利用自身血液离心制作的富含血小板的高浓度血浆,含有多种高浓度生长因子,在应用凝血酶激活后能够大量释放,可以促进创伤组织愈合和骨缺损修复,并能抑制感染,临床应用研究证实PRP具有良好的生物相容性和多功能性,组织修复效果确切,故已被运用于多个医学领域.主要介绍富血小板血浆的作用机制和骨科领域应用情况,对富血小板血浆促进骨与软组织修复以及抗炎的机制进行探讨,提出目前富血小板血浆在临床应用方面存在的问题.

Advances in studies on the application of platelet-rich plasma in the field of orthopedicsand the underlying mechanisms

Platelet-rich plasma(PRP) is a highly-concentrated plasma enriched in platelets and various growth factors. These growth factors will be released abundantly by platelets when PRP is activated by thrombin, which plays a key role in accelerating wound healing, bone repair, and meanwhile, in controlling of inflammatory process. Biocompatibility and versatility of PRP have been confirmed in clinical studies as well as its excellent effects on tissue reparation. These have lead to the extensive use of PRP in many medical fields as a therapeutic alternative. Mechanism of PRP in bone and tissue repair the application of PRP in the field of orthopedics is reviewed in this article. In addition, attempt is made to discuss about some problems still existing in the clinical application of PRP.
