Technical Problem
尽管利用生长因子(如VEGF)和采用显微外科技术的血管束包裹植入和带血管蒂筋膜包裹植入在血管重建方面取得了积极进展,但生长因子在体内衰减快,且其在体内游走可能引起副作用;而显微外科技术会给病人带来二次创伤,且供区有限,因而应用受限
Benefits of technology

Abstract
The application discloses a slow-release energy metabolism factor and bone fiber membrane and a preparation method thereof, and relates to the technical field of fiber membranes; the preparation method comprises the following steps: (1) dispersing an energy metabolism regulating factor in an organic solvent, then adding a high-molecular polymer, shaking and uniformly mixing, obtaining a spinning liquid, electrospinning, drying, and obtaining a fiber membrane base; (2) placing the fiber membrane base obtained in the step (1) in a polyphenol compound solution, standing, taking out and washing, and obtaining a fiber membrane grafted with the polyphenol compound; (3) placing the fiber membrane grafted with the polyphenol compound obtained in the step (2) in a fibronectin aqueous solution, standing, taking out and washing, and obtaining the slow-release energy metabolism factor and bone fiber membrane. The core-shell structure is prepared through the electrospinning process, the core layer slowly releases the energy metabolism factor, the shell layer modifies the surface of the fiber membrane base in combination with the polyphenol compound grafted protein, and thus the vascularized bone tissue regeneration is realized.
