Gelatin microsphere is firstly made by encapsulating bFGF into gelatin by special manufacture process, then this microsphere was combinated into PLGA conduit or PLGA film.when used, we need only pack the injury peripheral nerve, injury spinal cord, wounded pars encephalic with the PLGA conduit. The conduit or film can slowly release buff which would be absorbed by around tissues.bFGF was already proved to be nutritious to the regeneration and alive of neuron and protect injury neuron.bFGF can also promote morphogenesia and division of nerve cell which would raise the survival rate of neuron, guide the generation of axon etc.bFGF is one of the important factors of sustaining the normal survival of cholinergic nerve.

使用时，只需将此材料贴敷外周损伤神经伤患处，脊髓伤口，或在脑部开颅手术后填充于术后创面，可有效地在伤口局部缓慢地释放并由机体组织吸收bFGF等神经营养因子。bFGF等已被证明具有神经营养作用，可促进神经元的再生与存活，保护受损的神经元。bFGF等对神经细胞兼有促进形态发生与分裂作用，具有提高神经元的成活率、诱导轴突向外生长等功能，是维持前脑基底部胆碱能神经元正常生存的重要因素。
