摘要: 目的:明确血管内皮生长因子(VEGF)和转化生长因子-β(TGF-β)在先天性胫骨假关节(CPT)患者病变处骨膜组织中的含量,探讨其在发病机制中的作用。方法:采用免疫组织化学方法(SPTM法)对19例CPT患者病变骨膜组织内VEGF 和TGF-β的 表达进行检测,以10例正常骨膜为阴性对照, 15例胫骨闭合骨折骨折断端周围骨膜做阳性对照。结果:VEGF和TGF-β主要在CPT患者骨膜组织内血管内皮细胞胞浆中表达,VEGF和TGF-β表达量在假关节病变部位骨膜中少于创伤后骨折断端的骨膜(P<0.01),而与正常骨膜比较差异无显著性(P>0.05)。结论:CPT的发生可能与其骨膜组织中VEGF和TGF-β含量显著降低有关。

Abstract: Objective To approach the expressions of vascular endothelial growth factor (VEGF) and transforming growth factor-beta (TGF-β) in periosteum in patients with congenital pseudarthrosis of tibia(CPT) and elucidate the pathogenesis possibility. Methods The expressions of VEGF and TGF-β in 19 specimens from patients with CPT were detected by using immunohistochemical method.Ten normal periosteum from the healing site after tibia fracture were taken as negative group; 15 fresh periosteum from the close tibia fractures were positive group. Results VEGF and TGF-β expressed in vascular endothelial cytoplasm of periosteum. The expression levels of VEGF and TGF-β of CPT were lower than those in positive group(P<0.01). There were no significant differences of VEGF and TGF-β expressions between normal periosteum and CPT (P>0.05). Conclusion The decreasing of expression levels of VEGF and TGF-β in periosteum may be involved in pathogenesis of CPT.
