摘要:

文题释义:

静电纺丝伤口修复载药体系:是基于静电纺丝技术制备的一类负载药物的纳米纤维膜。作为伤口敷料或屏障材料,这种纤维膜/药物复合体系具有良好的机械性能、透气性和生物相容性,能够有效隔绝外界刺激保护伤口。进一步地,载药体系可选择负载多样化的活性成分用以促进组织恢复,最终达到促进伤口愈合的效果。该类材料是一类灵活度高、个性化强、可靠有效的伤口组织工程材料。

促愈合活性成分:是能够发挥促进伤口组织修复、加速伤口愈合的多类活性物质的合称,包括但不限于具有修复功能的细胞,各种促进组织愈合的生长因子或酶,维生素抗生素等促进或保护伤口的小分子药物,具有抗菌或抗炎作用的金属成分以及其他复杂的天然动植物成分等。这类活性成分的了解和选择常是构建伤口组织工程材料的关键。

 

摘要

背景:静电纺丝纤维膜作为近年来出现的一类性质优良的材料,为促进伤口软组织的愈合提供了新的途径。受益于其纤维基底和活性组分的多样性,静电纺丝伤口修复载药体系构建策略十分灵活。

目的:综述现阶段静电纺丝纤维载药体系的研究进展,依照静电纺丝纤维膜载药体系组分进行机制和功能特点的总结。

方法:利用互联网在Web of SciencePubMedCNKI、万方数据库中进行检索,中、英文检索关键词为“静电纺丝,伤口敷料,纳米纤维,伤口愈合和药物递送;electrospinningwound dressingnanofiberswound healingdrug deliver”,最终纳入105篇文献进入综述。

结果与结论:静电纺丝伤口修复载药体系组成灵活且构建策略多样。通过静电纺丝、不同作用导向的纤维聚合物、干细胞成分及纳米金属颗粒等各具功能生物活性“药物”,能构建多种有效的复合材料体系。该体系可针对伤口愈合过程中的各个环节进行作用,最终达到促进伤口软组织愈合的目的。这种优秀的载药体系/载药思路开拓了整个伤口治疗研究方向的视野,相比传统的凝胶和辅料治疗用品,其多机制、多功能、多可能性的特性使其成为更加先进的伤口处理生物材料。

Abstract:

BACKGROUNDAs an excellent material in recent years, electrospinning membrane provides a new method to promote the healing of wound. Based on the diversity of its fibrous base and active components, it is flexible to build a drug delivery system for electrospinning wound repair.

OBJECTIVE: To summarize the mechanism and functional characteristics of the components belonging to electrospinning fiber membrane drug-loading system, and to guide the selection of construction strategies for wound healing materials.

METHODS: The literature search was performed in Web of Science, PubMed, CNKI, and WanFang databases. The key words were “electrospinning, wound dressing, nanofibers, wound healing, drug deliver”. Ninety articles were included in this review finally.

RESULTS AND CONCLUSION: The construction strategies of electrospinning wound repair drug-delivery system were diverse. Through electrospinning technology, different polymers could be used to carry stem cell components or other small functional bioactive “drugs”, thus constructing a variety of effective composite systems. These materials might be applied to all aspects of the wound healing process, and finally achieve the purpose of promoting wound soft tissue healing. The excellent drug-loading system/drug-loading strategies have expanded the vision of wound treatment. Compared with traditional hydrogel and accessory treatment products, the multi-mechanism, function and possibility characteristics of electrospinning wound repair drug-delivery system determined its advantages in wound treatment.

Key words: electrospinning, wound healing, nanofibers, drug delivery, growth factors, polymer, wound dressing, biomaterials
