文题释义:
纤维蛋白凝胶:
是由纤维蛋白原与凝血酶反应后形成的立体网状结构、低抗原生物大分子材料,可塑性好,其在体内逐渐降解过程为药物缓慢均匀释放提供了良好条件,立体网状结构也允许新生毛细血管长入。以往的实验表明,纤维蛋白凝胶是骨形态发生蛋白2的良好载体,可以满足骨形态发生蛋白缓慢均匀释放的需要,避免其被血流很快冲走,并且骨形态发生蛋白与纤维蛋白凝胶复合后,骨诱导活性有所提高。
脊柱融合材料:主要包括自体骨、异体骨、人工骨材料,其中自体骨移植被公认为植骨融合的金标准。在脊柱融合内固定手术中,植骨融合是脊柱的长期稳定是根本方法,内固定无论如何发展,都只是一种短期内维持脊柱稳定的方法,所以植骨融合有非常重要的意义,而决定植骨融合效率的主要因素之一是脊柱融合材料。

 

摘要
背景:
骨形态发生蛋白2具有骨诱导作用,血管内皮生长因子对骨形成及修复起正性调节作用,那么二者用于骨融合的效果如何呢?
目的:观察重组人类血管内皮生长因子165和重组人类骨形态发生蛋白2复合纤维蛋白凝胶进行脊柱横突间融合的效果。
方法:将30只日本大耳白兔随机分3组,每组10只,实验组于L5-6横突间置入重组人类血管内皮生长因子165/重组人类骨形态发生蛋白2/纤维蛋白凝胶复合材料,对照组于L5-6横突间置入重组人类骨形态发生蛋白2/纤维蛋白凝胶复合材料,空白对照组于L5-6横突间置入纤维蛋白凝胶材料。置入后6周,进行影像学、生物力学与组织学检查。
结果与结论:实验组、对照组横突间成骨融合,且实验组成骨效果优于对照组,空白对照组无成骨。实验组成骨融合强度高于对照组(P < 0.01)。实验组成骨融合标本可见大量软骨细胞、骨细胞、成熟骨组织与胶原组织,对照组成骨融合标本可见大量软骨细胞、骨细胞及骨组织。结果表明,重组人类血管内皮生长因子165和重组人类骨形态发生蛋白2联合应用有助于促进成骨融合。

Abstract:

BACKGROUND: Bone morphogenetic protein 2 possesses osteoinduction, and vascular endothelial growth factor plays a positive regulatory role in osteogenesis and bone repair. So what will happen if both of them are used for spinal fusion?

 
OBJECTIVE: To investigate the effects of fibrin glue combined with vascular endothelial growth factor 165 and recombinant human bone morphogenetic protein 2 on intertransverse process fusion.
METHODS: Thirty Japanese white rabbits were randomized into three groups (n=10 per group): rabbits underwent intertransverse process fusion at the level of L5-6 with vascular endothelial growth factor 165/recombinant human bone morphogenetic protein 2/fibrin glue in experimental group, recombinant human bone morphogenetic protein 2/fibrin glue in control group, and fibrin glue in blank control group, respectively. At 6 weeks after implantation, observations of biomechanics, X-ray imaging and histology were performed.

RESULTS AND CONCLUSION: Osteogenic fusion between transverse processes could be found in experimental and control groups except for the blank control group, which was better in the experimental group. The strength of osteogenic fusion in the experimental group was significantly stronger than that in the control group (P < 0.01). Besides, abundant chondrocytes, osteocytes, mature bone tissues and collagens could be found in the osteogenic fusion specimen of the experimental group, and numerous chondrocytes, osteocytes and mature bone tissues observed in the osteogenic fusion specimen of the control group. In conclusion, fibrin glue combined with vascular endothelial growth factor 165 and recombinant human bone morphogenetic protein 2 can promote osteogenic fusion.
