    • 摘要: 目的 探讨7,8-二羟基黄酮(7,8-DHF)与施万细胞(SCs)对大鼠脱细胞同种异体神经支架(ANA)移植坐骨神经缺损后轴突再生和功能恢复的影响.方法 45只成年SD大鼠随机分为脱细胞神经支架(ANA)组、SCs组和7,8-DHF+SCs组.采用坐骨神经功能指数(SFI)和电生理方法检测运动功能的恢复,Western bolt检测再生神经内BDNF及其受体TrkB的蛋白表达,免疫荧光示踪PKH26标记的移植SCs,NF和S100免疫荧光法检测再生神经内轴突再生和髓鞘形成情况.结果 与SCs组比较,7,8-DHF+SCs组再生神经内BDNF和TrkB蛋白相对表达明显增高,PKH-26标记的SCs数量显著增高,NF和S100表达增强(P<0.05).与对照组比较,SCs组和7,8-DHF+SCs组神经传导速度增快、波幅增高、延迟期缩短、SFI指数增高,其中7,8-DHF+SCs组电生理和SFI指标优于SCs组(P<0.05).结论 7,8-DHF联合SCs对坐骨神经损伤后轴突再生、髓鞘形成和功能恢复的作用优于SCs组,其机制可能与7,8-DHF促进再生神经BDNF及其受体TrkB表达,进而促进移植的SCs存活有关.%Objective To study the effect of 7, 8-dihydroxyflavone (7, 8-DHF) and Schwann cells (SCs) transplantation on axon regeneration and function recovery after acellular nerve allograft (ANA) repair of the sciatic nerve gap in mice.Methods A total of 45 healthy SD rat were randomly divided into control group, SCs group and 7, 8-DHF + SCs group. SFI and electrophysiology were used to evaluate functional recovery. BDNF and TrkB protein were evaluated by western bolt, observe the fluorescence signal of SCs labeled with PKH-26 by using immunofluorescence, observe the axonal regeneration and myelination by using NF, S100 immunofluorescence. Results Compared with SCs group, the expression of BDNF, TrkB, NF, S100 and PKH-26 labeled SCs in 7, 8-DHF + SCs group were increased (P< 0. 05). Compared with control group, nerve conduction velocity and wave amplitude were significantly increased in SCs group and 7, 8-DHF + SCs group (P < 0. 05), however, incubation period were significantly decreased in two treatment group (P < 0. 05), the effect of 7, 8-DHF + SCs group was more powerful than SCs group (P< 0. 05), moreover, the SFI score of 7, 8-DHF + SCs group was higher than control group a nd SCs group. Conclusion The combined 7, 8-DHF and SCs transplantation treatment promoted axonal regeneration, myelination and function recovery significantly more than SCs treatments, which may be related to 7, 8-DHF upregulating BDNF and TrkB expression in the ANA, and promoting SCs survival.

    • 摘要: The repair, regeneration and functional recovery of peripheral nerve defects are the clinical problems needed to be solved urgently.Researches showed that the hollow conduits of bridging nerve defects only had the functions of support and isolation, but the composite conduits could simulate nerve regeneration microenvironment and possess biological activity, which could effectively guide the migration of Schwann cells and the regeneration of axons to achieve satisfactory effects of restoration and functional recovery.With the development of tissue engineering, regenerative medicine, biomaterial and the techniques of cells and molecular biology, the construction of biomimetic and functional nerve conduits to bridge long nerve defects has attracted more and more attention. This review will provide a brief overview of the construction strategy of nerve conduits repairing long nerve defects of peripheral nerves.%周围神经缺损修复、再生与功能恢复是临床亟待解决的问题,因桥接神经缺损的空腔导管仅具有支撑与隔离的作用,而复合导管能模拟神经再生微环境,具有生物活性,可有效地引导雪旺细胞的迁移和轴突的再生,达到较理想的修复效果和功能恢复.随着组织工程、再生医学和生物材料学以及细胞、分子生物学技术的发展,构建具有仿生性、功能性复合神经导管桥接修复神经长段缺损越来越受到关注.本文就神经导管用于周围神经长段缺损修复的构建策略做以概述.

    • 摘要: 背景:文献报道显示,胶原蛋白-明胶复合支架可促进周围神经缺损的早期恢复,但该结论尚未得到进一步证实。目的:观察胶原蛋白-明胶复合支架的细胞相容性及修复周围神经缺损的效果。方法:将胶原蛋白-明胶复合支架与SD大鼠骨髓间充质干细胞共培养5 d,观察两者复合形态。切除20只SD大鼠左侧30 mm的腓总神经,建立周围神经缺损模型。随机分组,实验组神经缺损处植入复合骨髓间充质干细胞的胶原蛋白-明胶复合支架,对照组植入自体神经,植入后16周,进行桥接体中段形态观察与电生理检测。结果与结论:①细胞与支架复合形态:骨髓间充质干细胞在支架上生长良好,与支架融合良好;②桥接体中段形态观察:两组有髓神经纤维密度比较差异无显著性意义(P>0.05),实验组有髓神经纤维直径、髓鞘厚度及神经组织百分比显著低于对照组(P0.05),实验组运动神经波幅、感觉神经潜伏期显著低于对照组(P0.05). The myelinated nerve fiber diameter, myelin sheaththickness and percentage of nerve tissues in the experimental group were significantly lower than those in the control group (P0.05). The amplitude of motor nerves and the latency of sensory nerves in the experimental group were significantly lower than those in the control group (P<0.05). To conclude, the col agen-gelatin scaffold holds a good cytocompatibity and is ideal for the repair of peripheral nerve defects.
