摘　　要：背景:目前临床上传统的给药途径(口服或静脉注射)面临难以透过血脑屏障问题,对于开放性重度创伤性脑损伤的临床治疗结果往往低于预期。水凝胶是一类极为亲水的三维网络结构凝胶,在水中迅速溶胀并在此溶胀状态可以保持。目前有部分实验应用可注射性功能水凝胶注射植入损伤部位以达到修复受损脑组织的目的,但这一治疗策略尚未应用于临床。目的:分析功能性水凝胶在创伤性脑损伤后组织修复中的作用,讨论水凝胶通过不同作用方式促进创伤性脑损伤后的神经组织再生,以期为创伤性脑损伤的临床治疗和基础研究提出新的思路。方法:以“hydrogels,functional hydrogel,composite hydrogels,traumatic brain injury,tissue repair,neural regeneration”“功能性水凝胶,创伤性脑损伤,组织修复,神经再生”为关键词在PubMed、Web of Science、中国知网和万方数据库检索2000年8月至2024年3月的相关文献。制定纳入和排除标准,通过阅读文献标题、摘要及全文内容进行筛选,最终纳入60篇相关文献进行综述。结果与结论:①基于分子设计的水凝胶可以模拟神经微结构,促进再生修复,模拟神经血管单元促进血管再生。②基于联合药物治疗原则的水凝胶可以递送内源性神经调控因子,包裹药物促进神经再生。③基于搭载干细胞恢复策略的水凝胶可以作为分子支架递送细胞治疗。④未来研究学者们还需进一步探索神经组织修复相关的功能性水凝胶,为创伤性脑损伤患者的治疗功能重建提供有效策略。BACKGROUND:At present,traditional drug delivery routes(oral or intravenous injection)in clinical practice face the problem of difficulty in penetrating the blood-brain barrier,and the clinical treatment of open severe traumatic brain injury is often lower than expected.Hydrogels are a class of extremely hydrophilic three-dimensional network structure gels,which swell rapidly in water and can be maintained in the swelling state.Hydrogels swell rapidly in water and can remain in this swollen state.At present,some experimental studies have applied injectable functional hydrogel injection into the injured site to achieve the purpose of repairing damaged brain tissue,but this treatment strategy has not been applied in clinic.OBJECTIVE:To analyze the role of functional hydrogels in tissue repair after traumatic brain injury,discuss the promotion of nerve tissue regeneration after traumatic brain injury through different action modes,so as to propose new ideas for clinical treatment and basic research of traumatic brain injury.METHODS:English key words“hydrogels,functional hydrogel,composite hydrogels,traumatic brain injury,tissue repair,neural regeneration”and Chinese key words“functional hydrogels,traumatic brain injury,tissue repair,nerve regeneration”were used to search the relevant articles published from August 2000 to March 2024 in PubMed,Web of Science,CNKI,and WanFang databases.The inclusion and exclusion criteria were formulated,and 60 relevant articles were finally included after being screened by reading the title,abstract,and full text of articles.RESULTS AND CONCLUSION:(1)The hydrogel based on molecular design can simulate the neural microstructure,promote regeneration and repair,and simulate the neurovascular unit to promote vascular regeneration.(2)Hydrogels based on the principle of combined drug therapy can deliver endogenous neuroregulatory factors,coating drugs to promote nerve regeneration.(3)Hydrogels based on stem cell recovery strategies can be used as molecular scaffolds to deliver cell
