文题释义:
Smad:Smads家族蛋白在将转化生长因子β信号从细胞表面受体传导至细胞核的过程中起到关键性作用,且不同的Smad介导不同的转化生长因子β家族成员的信号转导。转化生长因子β作为配体形成的受体复合物,激活Smads进入核内,共同激活或抑制它们调节的靶基因的转录。
骨不连:是指骨愈合过程的中断,是骨折术后常见的并发症之一,称为骨折不愈合。骨不连是骨折端在某些条件影响下愈合功能停止的表现。目前对骨不连的定义仍存在分歧:一般认为骨折8个月后骨折两端未能达到骨性连接(骨性愈合),称为骨不连;也有学者提出,骨折6个月后未能达到骨性连接即应确定为骨不连;根据美国食品药物管理局(FDA)的严格标准,骨折至少9个月,且近3个月内无愈合之迹象,可确定为骨不连。骨折在正常愈合所需的时间(一般为4个月内),仍未达到骨性连接,称为骨迟连。
 
摘要
背景:骨的修复再生是治疗骨类疾病的难点,骨形态发生蛋白具有强大的调控骨量的功能,是调控骨稳态及骨再生的重要蛋白分子。
目的:对骨形态发生蛋白信号通路在骨再生修复中的研究进展进行综述。
方法:以“骨形态发生蛋白,Smad分子,组织工程,骨缺损,骨修复,骨类疾病,研究进展,bone morphogenetic protein,Smads,Tissue engineering,Bone defect,bone repair,bone disease,Progress in research”为关键词,检索CNKI、PubMed、Elsevier ScienceDirect、Web of Science 等数据库1990至2018 年发表的与骨形态发生蛋白信号通路及骨再生修复中相关的文献,将所有文章进行初筛后,对保留的文献进一步的归纳和总结分析。

结果与讨论:骨形态发生蛋白分子在长骨、软骨、关节以及肌腱的生长发育中均发挥着重要的作用,骨形态发生蛋白2、7已投入临床上应用,用来治疗骨折不愈合、延迟愈合骨不连以及脊柱融合手术等,但骨形态发生蛋白对于骨再生修复中的强大的调控功能仍然值得进行更深一步的研究。骨形态发生蛋白及其相关分子在促进骨再生中取得了巨大进展,实现对骨形态发生蛋白信号的精准调节可能成为治疗骨类疾病的潜在治疗靶点。

Abstract:

BACKGROUND: Bone repair and regeneration is a difficulty in the treatment of bone diseases. Bone morphogenetic proteins can regulate bone mass and are critical for regulating bone homeostasis and bone regeneration.

OBJECTIVE: To review the research progress of bone morphogenetic protein signal pathway in bone regeneration and repair.
METHODS: Databases of CNKI, PubMed, Elsevier Science Direct, and Web of Science were retrieved with the keywords of “bone morphogenetic protein, Smads, tissue engineering, bone defect, bone repair, bone disease, progress in research” in English and Chinese, respectively from 1990 to 2018. Related literature on bone morphogenetic protein signaling pathways in bone regeneration was searched. After initial screening, eligible articles were further summarized and analyzed.
RESULTS AND CONCLUSION: Bone morphogenetic protein molecules play an important role in the growth and development of long bone, cartilage, tendon and joints. Bone morphogenetic proteins 2 and 7 have been applied in the treatment of fracture nonunion, delayed union, and spine fusion, but bone morphogenetic protein regulation in the bone regeneration and repair still needs a further investigation. Roles of bone morphogenetic proteins and its related molecules in bone regeneration have made great progress. Precise regulation of bone morphogenetic protein signals may become a potential therapeutic target for bone diseases.
