摘要:

文题释义:

生长板损伤:生长板又称骺板,是儿童未成熟长骨末端控制骨骼纵向生长的软骨区域,是生长期骨骼中最为脆弱的区域,创伤、感染、药物、放疗、肿瘤等多种因素均可导致其损伤。由于生长板软骨再生能力差,损伤生长板内的软骨组织通常会被不需要的骨组织取代,进而形成“骨桥”,导致长骨生长发育障碍、成角或旋转畸形等。
血小板衍生生长因子BB:是血小板衍生生长因子家族成员之一,作为其中活性最高、功能最强细胞因子具有促有丝分裂、分化、趋化和血管生成等作用,参与多种疾病的病理过程。


背景:在生长板损伤炎症初期,血小板衍生生长因子BB通过促进间充质祖细胞浸润、软骨形成、成骨反应以及调控骨重塑来促进生长板损伤的修复。
目的:总结血小板衍生生长因子BB在生长板损伤修复中的作用机制。
方法:检索PubMed、维普、万方数据和中国知网数据库,中文检索词为“生长板损伤,骨桥形成,血小板衍生因子BB,修复”,英文检索词为“growth plate injury,bone bridge,PDGF-BB,repair”,最终筛选66篇文章进行综述。 

结果与结论:生长板损伤经历早期炎症、血管重建、纤维骨化、结构重塑等病理进程,伴随着软骨细胞、血管内皮细胞、干细胞、成骨细胞、破骨细胞多种细胞交叉对话。血小板衍生生长因子BB作为损伤早期炎症反应的重要因子通过介导多种细胞炎症反应调控损伤修复过程,靶向血小板衍生生长因子BB介导的炎症刺激可能通过改善破骨细胞、成骨细胞、软骨细胞功能活性延缓生长板损伤骨桥形成进程,实现生长板损伤修复。血小板衍生生长因子BB对生长板损伤部位的血管生成和骨修复组织形成以及未损伤生长板的软骨内骨延长功能具有重要作用,抑制血小板衍生生长因子BB启动的血管形成与软骨内成骨之间的偶联效应将有可能实现生长板损伤修复。

Abstract: BACKGROUND: In the initial stage of growth plate injury inflammation, platelet-derived growth factor BB promotes the repair of growth plate injury by promoting mesenchymal progenitor cell infiltration, chondrogenesis, osteogenic response, and regulating bone remodeling.
OBJECTIVE: To elucidate the action mechanism of platelet-derived growth factor BB after growth plate injury.
METHODS: PubMed, VIP, WanFang, and CNKI databases were used as the literature sources. The search terms were “growth plate injury, bone bridge, platelet-derived growth factor BB, repair” in English and Chinese. Finally, 66 articles were screened for this review.
RESULTS AND CONCLUSION: Growth plate injury experienced early inflammation, vascular reconstruction, fibroossification, structural remodeling and other pathological processes, accompanied by the crosstalk of chondrocytes, vascular endothelial cells, stem cells, osteoblasts, osteoclasts and other cells. Platelet-derived growth factor BB, as an important factor in the early inflammatory response of injury, regulates the injury repair process by mediating a variety of cellular inflammatory responses. Targeting the inflammatory stimulation mediated by platelet-derived growth factor BB may delay the bone bridge formation process by improving the functional activities of osteoclasts, osteoblasts, and chondrocytes, so as to achieve the injury repair of growth plate. Platelet-derived growth factor BB plays an important role in angiogenesis and bone repair tissue formation at the injured site of growth plate and intrachondral bone lengthening function of uninjured growth plate. Inhibition of the coupling effect between angiogenesis initiated by platelet-derived growth factor BB and intrachondral bone formation may achieve the repair of growth plate injury.
