摘要 背景:脊髓损伤是由创伤性或非创伤性事件引起的一种神经系统疾病,常导致损伤节段以下严重功能障碍。近年来,神经干细胞移植被认为在调控脊髓损伤后的炎症反应、抑制胶质瘢痕的过度增生以及促进神经再生方面具有显著的治疗潜力。目的:综述并讨论针刺及神经干细胞移植疗法在抑制脊髓损伤诱导的继发性损伤中的潜在作用机制,深入探讨其治疗脊髓损伤的科学依据。方法:以“脊髓损伤,针刺,神经干细胞,SDF-1α/CXCR4轴”为中文检索词,以“Spinal cord injury,acupuncture,neural stem cells,SDF-1α/CXCR4 axis”为英文检索词,分别检索PubMed、Elsevier、万方及中国知网数据库,最终纳入96篇文献,汇总分析了针刺联合神经干细胞治疗脊髓损伤的相关研究成果,总结了这一联合疗法在治疗脊髓损伤后继发性损伤中的相关机制。结果与结论:①基质细胞衍生因子1α(stromal-derived factor 1α,SDF-1α)/CXC趋化因子受体4(chemokine receptor 4,CXCR4)轴在神经干细胞移植治疗脊髓损伤中扮演着至关重要的角色,该信号传导机制不仅影响神经干细胞的迁移、增殖和分化,更是决定干细胞归巢至损伤部位效率的关键因素。因此,针对该轴线的调控,对于提升脊髓损伤的治疗效果具有重要意义。②针刺作为一种传统中医疗法,在脊髓损伤的继发性损伤调控中展现出独特的优势,它能够通过调节炎症反应、抑制细胞凋亡、改善微循环、减少神经胶质瘢痕形成以及对抗氧化应激等多种途径,有效减轻脊髓损伤后的继发性损伤。③针刺还能够影响SDF-1α/CXCR4轴的表达与功能,从而增强神经干细胞的归巢和存活能力,促进神经再生和功能恢复。④结合针刺与干细胞移植的疗法,是一种创新且较好的脊髓损伤治疗策略,适用于修复神经环路,它结合了传统中医的智慧与现代生物技术的优势,为脊髓损伤患者提供了新的治疗选择。然而,目前这种联合疗法仍处于研究和探索阶段,其长期疗效和安全性尚需进一步验证。⑤综合而言,针刺及神经干细胞移植治疗脊髓损伤具有巨大的临床应用潜力,但仍需深入研究和优化治疗方案。未来,期待通过更多的临床试验和机制研究,进一步揭示这一疗法的疗效机制和最佳适应证,为脊髓损伤患者带来更好的康复希望和更高效的治疗效果。 BACKGROUND:Spinal cord injury is a neurological disorder caused by traumatic or non-traumatic events,often leading to severe functional impairment below the injured segment.In recent years,neural stem cell transplantation has been considered to have significant therapeutic potential in regulating the inflammatory response after spinal cord injury,inhibiting excessive proliferation of glial scars,and promoting nerve regeneration.OBJECTIVE:To review and discuss the potential mechanism of action of acupuncture and neural stem cell transplantation therapy in inhibiting spinal cord injury-induced secondary injury,and to delve into the scientific basis for its treatment of spinal cord injury.METHODS:PubMed,Elsevier,WanFang,and CNKI databases were searched using“spinal cord injury,acupuncture,neural stem cells,SDF-1α/CXCR4 axis”as Chinese and English search terms.Totally 96 articles were finally included.The research findings of acupuncture combined with neural stem cells in the treatment of spinal cord injury were summarized and analyzed,and the mechanism of this combination therapy in the treatment of secondary injury after spinal cord injury was summarized.RESULTS AND CONCLUSION:(1)The stromal-derived factor 1α(SDF-1α)/chemokine receptor 4(CXCR4)axis plays a crucial role in neural stem cell transplantation for spinal cord injury.This signaling mechanism not only affects neural stem cell migration,proliferation,and differentiation,but is also a key factor in determining the efficiency of stem cell homing to the injury site.Therefore,the regulation of targeting this axis is of great significance in enhancing the therapeutic effect of spinal cord injury.(2)Acupuncture,as a traditional Chinese medicine therapy,shows unique advantages in the regulation of secondary injury in spinal cord injury.It can effectively reduce secondary injury after spinal cord injury by regulating inflammatory response,inhibiting apoptosis,improving microcirculation,reducing glial scar formation,and counteracting oxidative stress.(3)Acupuncture was also able to influence the expression and function of the SDF-1α/CXCR4 axis,thereby enhancing the homing and survival ability of neural stem cells and promoting nerve regeneration and functional recovery.(4)The therapy combining acupuncture and stem cell transplantation is an innovative treatment strategy for spinal cord injury and suitable for repairing neural circuits.It combines the wisdom of traditional Chinese medicine with the advantages of modern biotechnology,providing a new treatment option for spinal cord injury patients.However,this combination therapy is still in the research and exploration stage,and its long-term efficacy and safety need to be further verified.(5)Taken together,acupuncture and neural stem cell transplantation for the treatment of spinal cord injury has great potential for clinical application,but in-depth research and optimization of treatment options are still needed.In the future,we look forward to further revealing the efficacy mechanism and optimal indications of this therapy through more clinical trials and mechanism studies,so as to bring better hope of recovery and more efficient therapeutic effects to spinal cord injury patients.
