摘要:


文题释义:

近红外光响应水凝胶:由聚合物网络和近红外光响应官能团组成,通过光敏基团将近红外光信号转化为物理或化学信号,继而调控水凝胶的理化性质。由于其能够实现远程时空控制和动态调节材料行为,成为一类新兴的生物医用材料。
近红外光响应水凝胶的组织工程应用特性:近红外光响应水凝胶不仅可作为骨引导生物支架,而且具有光热效应并可实现生长因子药物递送等过程,从而实现诊断治疗一体化,拥有可视化成像、精准监测细胞分子水平变化、动态可调的组织再生修复等功能。


背景:近红外光响应水凝胶具有高度时空精准性、远程可调性及安全无创性等多种优异特性,为组织工程的发展提供了新的探索方向。

目的:总结近年来近红外光响应水凝胶在组织工程领域的应用进展。
方法:利用计算机检索中国知网及PubMed数据库相关文献,中文检索词为“近红外光响应水凝胶、组织工程、骨缺损、骨修复、骨再生、伤口愈合、伤口敷料、血管生成”,英文检索词为“near infrared responsive hydrogels,tissue engineering,bone defect,bone repair,bone regeneration,wound healing,wound dressing,angiogenesis”,检索时限为2006年5月至2022年10月,部分经典文献延长检索时间限制,分析所得文献的摘要及内容,通过纳入和排除标准得到相关文献,最终纳入97篇符合标准的文献进行综述。

结果与结论:①近红外光响应材料通过控制感染减轻炎症、促进血管生成、促进成骨细胞分化和新骨形成等过程参与组织修复。②近红外光响应材料可以通过构建具有光热效应的热敏水凝胶或者利用光化学反应制备近红外光响应水凝胶。③近红外光响应水凝胶作为伤口敷料在软组织愈合再生过程中,通过聚合物单体的聚合作用实现快速止血及组织黏附等作用,利用光热纳米材料局部光热效应促进抗菌抗炎、促进血管形成和上皮再生等功能。④近红外光响应水凝胶在骨重建修复过程中,通过促进间充质干细胞成骨分化、刺激热休克蛋白的表达、增加血管新生等发挥促进修复作用。⑤目前近红外光响应水凝胶与多种治疗策略的组合已呈现出显著协同治疗功能,也被逐步开发应用于其他组织重建和疾病治疗场景。

Abstract: BACKGROUND: Near infrared responsive hydrogels, have a variety of excellent properties such as high spatial and temporal precision, remote tunability, and safety and non-invasiveness, providing a new direction of exploration for the development of tissue engineering.
OBJECTIVE: To summarize the application progress of near infrared responsive hydrogels in the field of tissue engineering in recent years.
METHODS: The literature search was performed on PubMed and CNKI databases. The keywords were “near infrared responsive hydrogels, tissue engineering, bone defect, bone repair, bone regeneration, wound healing, wound dressing, angiogenesis” in Chinese and English. The search time limit was from May 2006 to October 2022 and extended for some classical literature. The abstracts and contents of the retrieved literature were analyzed, and the relevant literature was obtained according to inclusion and exclusion criteria. Finally, 97 articles were included for review.
RESULTS AND CONCLUSION: (1) Near infrared responsive materials are involved in tissue repair by controlling infection and reducing inflammation, promoting angiogenesis, osteoblast differentiation and new bone formation. (2) Near infrared responsive hydrogel can be prepared by constructing a thermosensitive hydrogel with a photothermal effect or by using a photochemical reaction. (3) Near infrared responsive hydrogels as wound dressings perform various functions such as rapid hemostasis, tissue adhesion through polymerization of polymer monomers, antibacterial and anti-inflammatory effects, and promotion of angiopoiesis and epithelial regeneration through the local photothermal effect of photothermal nanomaterials during soft tissue healing and regeneration. (4) Near infrared responsive hydrogels function during bone reconstruction and repair by promoting osteogenic differentiation of mesenchymal stem cells, stimulating the expression of heat shock proteins, and increasing angiogenesis. (5) Near infrared responsive hydrogels present a combination of multiple therapeutic strategies with significant synergistic therapeutic functions and are also being progressively developed for application in other tissue reconstruction and disease treatment scenarios. 

Key words: near infrared, hydrogel, tissue engineering, regenerative medicine, bone regeneration, bone repair, wound dressing, photothermal effect
