文题释义:
魔芋葡甘聚糖:是一种从魔芋块茎中提取出的水溶性非离子型线性高分子多糖,具有良好的亲水性、胶凝性、成膜性、增稠性及生物活性,被作为一种重要的可溶性膳食纤维、工业生产原料或者添加剂,广泛应用于食品、医药、化工、纺织、造纸、石油等诸多领域。
魔芋葡甘聚糖/纳米羟基磷灰石/胶原组织工程纤维环支架的优势:魔芋葡甘聚糖力学性能好,但降解速率偏慢;胶原力学性能差,但降解速率偏快;通过改变二者的配比,可以调节支架材料的降解速率。纳米羟基磷灰石在支架材料中能起到增强相的作用。


 

背景:研究符合天然椎间盘生物学结构与功能的组织工程移植物,对退变椎间盘进行生物学功能重建,已逐步成为治疗椎间盘退变性疾病较理想的解决方案。
目的:设计构建一种新型的组织工程纤维环支架材料。
方法:以魔芋葡甘聚糖、纳米羟基磷灰石和胶原为原料,依次应用湿法纺丝、化学交联、冷冻干燥等技术构建一种全新的组织工程化纤维环支架,采用X射线衍射分析和傅里叶变换红外光谱仪对其进行定性成分分析,同时对其理化性能、生物力学性能及细胞相容性进行分析。
结果与结论:魔芋葡甘聚糖/纳米羟基磷灰石/胶原组织工程椎间盘纤维环支架呈三维立体多孔结构,孔径(425.8±47.3)μm,孔隙率为(73.4±5.6)%,吸水率为(718.6±24.3)%,具有与天然纤维环相似的抗压强度,具有良好的生物相容性,无细胞毒性。结果表明魔芋葡甘聚糖/纳米羟基磷灰石/胶原组织工程椎间盘纤维环支架具有适宜的三维多孔结构、生物相容性、孔隙率、吸水率和生物力学强度。

Abstract:

BACKGROUND: Tissue-engineered transplantation technique has become an ideal therapeutic regimen for degenerative disc diseases through reconstituting the biological functions of the degenerated intervertebral discs.

OBJECTIVE: To construct a novel tissue-engineered annular fibrosus scaffold.
METHODS: Konjac glucomannan, nano-hydroxyapatite and collagen were used to fabricate a new tissue-engineered annular fibrosus scaffold by wet spinning, chemical crosslinking, and freeze drying methods. Afterwards, X-ray diffraction and Fourier transform infrared spectrometer were used to analyze the scaffold qualitative components, physico-chemical property, biomechanical performance and cytocompatibility. 
RESULTS AND CONCLUSION: The bionic scaffold had a three-dimensional porous structure, with the average pore size of (425.8±47.3) μm, the average porosity of (73.4±5.6)%, and the water absorption of (718.6±24.3)%. In addition, the compressive strength of the scaffold was similar with that of the natural annular fibrosus. More importantly, the scaffold had good biocompatibility without cytotoxicity. These results show that the tissue-engineered annular fibrosus scaffold constructed by konjac glucomannan, nano-hydroxyapatite and collagen has proper three-dimensional porous structure, biocompatibility, porosity, water absorption and biomechanical strength.
