摘要:
文题释义:
海藻酸钠:是一种线性的共聚产物,其结构包括β-1,4-糖苷键连接的α-L-古洛糖醛酸(G单元)和β-D-甘露糖醛酸(M单元)。
背景:天然来源的多糖海藻酸钠具有含量高、成本低、生物相容性好、生物可降解性好等特点,在可注射型水凝胶的生产中得到了广泛应用,成为制备可注射水凝胶的理想原料之一。
目的:就海藻酸钠的性质、可注射海藻酸钠水凝胶的制备及其在组织工程中的应用进展进行综述。结果与结论:由于海藻酸钠来源广泛,分子链结构上存在着许多可改性基团,可用各种共价交联或非共价交联的方法合成多种性能优良的可注射型水凝胶;将其他具有生物功能的分子引入海藻酸钠水凝胶中,可以调节其功能、拓宽其应用范围。另外,由于生物相容性和生物可降解性等优良的物理化学特性,可注射型海藻酸钠水凝胶在生物医学方面有着广泛的发展潜力,海藻酸钠水凝胶在体外与各种药物、细胞、因子或其他生物作用分子均匀调配,在人体内可形成凝胶,在基因载体、细胞支架和创口修复中起着举足轻重的作用。

文题释义:
海藻酸钠:是一种线性的共聚产物,其结构包括β-1,4-糖苷键连接的α-L-古洛糖醛酸(G单元)和β-D-甘露糖醛酸(M单元)。该文介绍了海藻酸钠的结构和理化性质,并且作为天然高分子材料,海藻酸钠已是食品领域安全可食用材料,单纯海藻酸钠在医学领域应用已无法现代的医学发展,进而采用海藻酸钠作为药物、细胞或者填充的基质;重点阐述了可注射海藻酸钠水凝胶的制备方法,总结了可注射海藻酸钠水凝胶的制备的基本原理和不同的制备方法的优势和弊端,为可注射海藻酸钠水凝胶制备方法相关局限提供新思路;概述了可注射海藻酸钠水凝胶在组织工程主要的应用方面,可注射海藻酸钠水凝胶为创口修复提供了极大的便利,不仅能够迅速吻合创口,保护创口受到二次损伤,可携带相关修复治疗因子或干细胞,还可保护干细胞免受免疫清除的同时提供干细胞生长环境。
