摘要:

文题释义:
聚偏氟乙烯:是一种半结晶型聚合物,具有良好的化学稳定性、生物相容性和优异的压电性能。
仿生骨膜:是一种仿照天然骨膜结构和功能设计的人工材料或组织工程支架,旨在促进骨缺损修复、骨再生及血管神经再生。

背景:在使用引导骨再生技术修复骨缺损的过程中,屏障膜既要阻止周围软组织进入骨缺损区又要使成骨细胞优先长入,故研究一种具有优良性能的屏障膜对该技术的实施有重要意义。
目的:制备掺锌镁聚偏氟乙烯仿生骨膜,分析该骨膜的性能。
方法:通过静电纺丝技术分别制备聚偏氟乙烯仿生骨膜(记为PVDF膜)、掺1%,2%,3%ZnCl2的聚偏氟乙烯仿生骨膜(分别记为1%ZnCl2-PVDF、2%ZnCl2-PVDF、3%ZnCl2-PVDF膜)、掺1%,2%,3%MgCl2的聚偏氟乙烯仿生骨膜(分别记为1%MgCl2-PVDF、2%MgCl2-PVDF、3%MgCl2-PVDF膜)以及掺1%,2%,3%(ZnCl2+MgCl2)的聚偏氟乙烯仿生骨膜[分别记为1%(ZnCl2+MgCl2)-PVDF、2%(ZnCl2+MgCl2)-PVDF、3%(ZnCl2+MgCl2)-PVDF膜]。表征聚偏氟乙烯仿生骨膜的微观形貌、β相含量、锌镁离子释放情况、最大拉伸负荷与水接触角。
结果与结论:①扫描电镜显示,10组骨膜纳米纤维相互交错穿插形成网状,其中,PVDF、1%ZnCl2-PVDF、1%MgCl2-PVDF、1%(ZnCl2+ MgCl2)-PVDF膜的质地均匀、纤维直径大小较为一致。骨膜浸泡于PBS中14 d,1%ZnCl2-PVDF、1%MgCl2-PVDF、1%(ZnCl2+MgCl2)-PVDF膜的锌镁离子释放较为稳定。结合微观形貌与锌镁离子释放情况,后续对PVDF、1%ZnCl2-PVDF、1%MgCl2-PVDF、1%(ZnCl2+MgCl2)-PVDF膜进行相关检测。②添加1%ZnCl2和(或)1%MgCl2对聚偏氟乙烯仿生骨膜的β相含量无明显影响。PVDF膜的最大拉伸负荷最小,1%ZnCl2-PVDF膜的最大拉伸负荷最大。添加1%ZnCl2和(或)1%MgCl2对聚偏氟乙烯仿生骨膜的水接触角无明显影响。③结果表明,掺入1%ZnCl2和(或)1%MgCl2的聚偏氟乙烯仿生骨膜具有良好的表面形貌与机械性能。

Abstract: BACKGROUND: In the process of repairing bone defects using guided bone regeneration technology, the barrier membrane needs to prevent surrounding soft tissue from entering the bone defect area while also allowing osteoblasts to preferentially grow into the area. Therefore, researching a barrier membrane with excellent performance is of great significance for the implementation of this technology.
OBJECTIVE: To prepare zinc-magnesium polyvinylidene fluoride biomimetic periosteum and analyze its performance. 
METHODS: Polyvinylidene fluoride biomimetic periosteum was prepared using electrospinning technology, including pure polyvinylidene fluoride membranes (denoted as PVDF membranes), polyvinylidene fluoride biomimetic periosteum doped with 1%, 2%, and 3% ZnCl2 (denoted as 1%ZnCl2-PVDF, 2%ZnCl2-PVDF, and 3%ZnCl2-PVDF membranes, respectively), polyvinylidene fluoride biomimetic periosteum doped with 1%, 2%, and 3% MgCl2 (denoted as 1%MgCl2-PVDF, 2%MgCl2-PVDF, and 3%MgCl2-PVDF membranes, respectively), and polyvinylidene fluoride biomimetic periosteum doped with 1%, 2%, and 3% (ZnCl2+MgCl2) [denoted as 1%(ZnCl2+MgCl2)-PVDF, 2%(ZnCl2+MgCl2)-PVDF, and 3%(ZnCl2+MgCl2)-PVDF membranes, respectively]. The microstructure, β-phase content, zinc and magnesium ion release, maximum tensile load, and water contact angle of the polyvinylidene fluoride biomimetic bone membranes were characterized.
RESULTS AND CONCLUSION: (1) Scanning electron microscopy showed that the nanofibers of the 10 groups of periosteum were interwoven to form a network. Among them, the PVDF, 1%ZnCl2-PVDF, 1%MgCl2-PVDF, and 1%(ZnCl2+MgCl2)-PVDF membranes had a uniform texture and relatively consistent fiber diameters. After the bone membranes were immersed in PBS for 14 days, the release of zinc and magnesium ions from the 1%ZnCl2-PVDF, 1%MgCl2-PVDF, and 1%(ZnCl2+MgCl2)-PVDF membranes was relatively stable. Combining microscopic morphology and zinc and magnesium ion release, subsequent tests were conducted on PVDF, 1%ZnCl2-PVDF, 1%MgCl2-PVDF, and 1%(ZnCl2+MgCl2)-PVDF membranes. (2) The addition of 1%ZnCl2 and/or 1%MgCl2 had no significant effect on the β-phase content of the polyvinylidene fluoride biomimetic bone membrane. The PVDF membrane had the lowest maximum tensile load, while the 1%ZnCl2-PVDF membrane had the highest maximum tensile load. The addition of 1%ZnCl2 and/or 1%MgCl2 had no significant effect on the water contact angle of the polyvinylidene fluoride biomimetic periosteum. (3) The results show that the polyvinylidene fluoride biomimetic periosteum doped with 1%ZnCl2 and/or 1%MgCl2 has good surface morphology and mechanical properties.
