骨折的愈合问题是骨科医师长久以来关心的问题,骨折愈合是骨组织完全性再生的过程,各种细胞因子在不同的骨折愈合阶段发挥不同的作用;随着外科技术的不断成熟与完善,目前仍有约10%的骨折病人存在骨折不愈合或延迟愈合的情况。近年来,有相关研究表明,血小板衍生生长因子(PDGF)对于骨折不愈合或延迟愈合病人有着良好的促进骨折愈合作用。PDGF作为一种有效的有丝分裂原,对包括成骨系细胞在内的多种间充质细胞有刺激作用。对于PDGF的进一步研究,能够对临床骨折患者提供新的更优的选择。本文就PDGF促进骨折愈合机制以及研究进展作一综述。 Fracture healing is a process of complete regeneration of bone tissue. Various cytokines play different roles in different stages of fracture healing. With the continuous maturity and improvement of surgical technology, about 10% of fracture patients still have nonunion or delayed union. In recent years, related studies have shown that platelet-derived growth factor (PDGF) has a good effect on promoting fracture healing in patients with nonunion or delayed union.

ABSTRACT
Fracture healing is a process of complete regeneration of bone tissue. Various cytokines play different roles in different stages of fracture healing. With the continuous maturity and improvement of surgical technology, about 10% of fracture patients still have nonunion or delayed union. In recent years, related studies have shown that platelet-derived growth factor (PDGF) has a good effect on promoting fracture healing in patients with nonunion or delayed union. As an effective mitogen, PDGF can stimulate a variety of mesenchymal cells including osteoblasts. The further study of PDGF can provide a new and better choice for clinical fracture patients. This article reviews the mechanism and research progress of PDGF in promoting fracture healing.

1. 引言
随着现代交通工具的发展以及人口老龄化问题日趋严重,骨折的发生率也随之水涨船高。暴力创伤及老龄骨质疏松造成的骨丢失和结构损伤会导致骨骼脆弱,表现为骨量低、骨几何形状变化、微结构改变及材料性能缺陷 [

] 在一项流行病学研究中表明美国每年骨折的病例超过200万,占全年医疗保健费用近200亿美元。其中约有10%的患者后期出现骨折不愈合或者延迟愈合的情况,这不仅对患者及家属心理造成负担,二次手术带来的经济问题也不容小觑,更有甚者严重影响患者生存质量。
