摘要:

文题释义:
继发性脊髓损伤:是在脊髓原发性损伤的基础上,经血管、氧自由基、兴奋性氨基酸、一氧化氮等因素机制造成的继发性损伤。由于继发性损伤常常发生较快、窗口期短,后果严重,从而导致临床上对于继发性脊髓损伤的修复性治疗效果不甚理想,改善继发性损伤是治疗脊髓损伤的重点。
神经生长因子:广泛分布于机体各组织器官中(包括脑),在靶组织中的浓度与交感神经和感觉神经在靶区分支的密度和mRNA含量有关。神经生长因子能促进中枢和外周神经元的生长、发育、分化、成熟,维持神经系统的正常功能,加快神经系统损伤后的修复。

背景:大量文献报道了富血小板血浆、水凝胶治疗脊髓损伤的作用及其机制,但较少文章归纳总结它们治疗脊髓损伤的策略。
目的:归纳总结脊髓损伤的病理进程,富血小板血浆和水凝胶单独及联合应用修复脊髓损伤的策略。
方法:应用计算机检索PubMed和中国知网数据库建库至2024年3月之前发表的文献,中文检索词为“脊髓损伤,富血小板血浆,水凝胶”,英文检索词为“spinal cord injury,spinal cord,Platelet-rich plasma,hydrogel,angiogenesis,neuralgia,combination therapy”,按照纳入和排除标准对文献进行筛选,最终纳入128篇文献进行综述分析。
结果与结论:①富血小板血浆的分类复杂多样,在脊髓损伤的修复性治疗应用中的效果也是各有不同,但都表现出一定的积极的效果,即具有一定的促进轴突再生、刺激血管生成、治疗神经性疼痛等作用;②富血小板血浆的作用主要得益于其所含的生长因子等成分;③水凝胶的种类也很多,在脊髓损伤的修复性治疗中主要起到填充、模拟细胞外基质、搭载药物与生物产品、作为支架搭载细胞等作用;④与单一的治疗方式相比,富血小板血浆和水凝胶联合治疗可更有效地促进神经再生和脊髓功能的恢复。

Abstract: BACKGROUND: A large number of articles have reported the effect and mechanism of platelet-rich plasma and hydrogel in the treatment of spinal cord injury, but few articles have summarized their treatment strategies for spinal cord injury. 

OBJECTIVE: To summarize the pathological process of spinal cord injury and the strategies of repairing spinal cord injury with platelet-rich plasma and hydrogel alone and in combination.

METHODS: PubMed and CNKI databases were searched for articles published from inception to March 2024 by computer. The Chinese search terms were “spinal cord injury, platelet-rich plasma, hydrogel.” The English search terms were “spinal cord injury, spinal cord, platelet-rich plasma, hydrogel, angiogenesis, neuralgia, combination therapy.” Articles were screened according to inclusion and exclusion criteria, and 128 articles were finally included for review and analysis.
RESULTS AND CONCLUSION: (1) The classification of platelet-rich plasma is complex and diverse, and the effects of platelet-rich plasma in the repair treatment of spinal cord injury are various, but they all show certain positive effects, that is, they can promote axon regeneration, stimulate angiogenesis, and treat neuropathic pain and so on. (2) The effect of platelet-rich plasma is mainly due to the growth factors contained in platelet-rich plasma. (3) There are many types of hydrogels, which mainly play the role of filling, simulating extracellular matrix, carrying drugs and biological products, and carrying cells as scaffolds in the repair treatment of spinal cord injury. (4) Compared with single therapy, combination therapy of platelet-rich plasma and hydrogel can promote nerve regeneration and spinal cord function recovery more effectively.

Key words: spinal cord injury, primary injury, secondary injury, platelet-rich plasma, hydrogel, vascular regeneration, axon regeneration, nerve pain, combination therapy
