J Exp Orthop:牵张成骨后使用富含血小板的血浆不会减少骨骼肌纤维化

2018-08-07 MedSci MedSci原创

牵张成骨术后经常发生由胶原沉积导致骨骼肌纤维化。虽然有研究报告富含血小板血浆(PRP)可影响损伤后的组织愈合,但目前的研究结果仍存在争议。本研究的重点是确定PRP是否能减少由牵张成骨引起的骨骼肌纤维化。在8周龄野生型小鼠上进行胫骨截骨术,并且在截骨术后1周开始,胫骨以0.42mm/天的速度牵张2周。在完成牵引后(截骨术后3周),立即将PRP或磷酸盐缓冲盐水(作为假)注入腓肠肌(GC)肌肉。采集并分

牵张成骨术后经常发生由胶原沉积导致骨骼肌纤维化。虽然有研究报告富含血小板血浆(PRP)可影响损伤后的组织愈合,但目前的研究结果仍存在争议。本研究的重点是确定PRP是否能减少由牵张成骨引起的骨骼肌纤维化。

在8周龄野生型小鼠上进行胫骨截骨术,并且在截骨术后1周开始,胫骨以0.42mm/天的速度牵张2周。在完成牵引后(截骨术后3周),立即将PRP或磷酸盐缓冲盐水(作为假)注入腓肠肌(GC)肌肉。采集并分析GC肌肉。

结果显示,牵张成骨术后PRP组和对照组胶原组织的数量和面积均增加,但两组在所有时间点的变化均无明显差异(p = 0.89,0.45,0.33和0.52,分别为4,6,8和10周)。

综上所述,该研究结果表明,由于牵张成骨,PRP没有明显减少骨骼肌纤维化。
