摘要:

创伤性脊髓损伤主要表现为感觉、运动、自主神经功能障碍,严重影响日常生活能力。这些不良结果与脊髓损伤机制复杂、中枢神经元的再生能力有限以及创伤性损伤形成的抑制环境密切相关。微循环障碍是脊髓继发性损伤的重要病理生理机制。多种治疗药物已被证明可以改善创伤环境、减轻继发损伤或促进再生/修复。其中,脊髓微循环已成为治疗脊髓损伤的重要靶点,以微循环为靶点的药物干预可改善脊髓损伤的微环境、促进脊髓损伤的恢复。这些药物靶向脊髓微循环的结构和功能,对维持脊髓神经元、轴突和胶质细胞的正常功能至关重要。综述就脊髓微循环在脊髓损伤中的病理生理作用,包括脊髓微循环的结构和脊髓损伤引起的脊髓微循环的组织病理学改变进行了讨论,并对SCI后针对脊髓微循环的药物治疗进展进行了总结。

Abstract: Traumatic spinal cord injury is a devastating disorder characterized by sensory, motor, and autonomic dysfunction that severely compromises an individual’s ability to perform activities of daily living. These adverse outcomes are closely related to the complex mechanism of spinal cord injury, the limited regenerative capacity of central neurons, and the inhibitory environment formed by traumatic injury. Disruption to the microcirculation is an important pathophysiological mechanism of spinal cord injury. A number of therapeutic agents have been shown to improve the injury environment, mitigate secondary damage, and/or promote regeneration and repair. Among them, the spinal cord microcirculation has become an important target for the treatment of spinal cord injury. Drug interventions targeting the microcirculation can improve the microenvironment and promote recovery following spinal cord injury. These drugs target the structure and function of the spinal cord microcirculation and are essential for maintaining the normal function of spinal neurons, axons, and glial cells. This review discusses the pathophysiological role of spinal cord microcirculation in spinal cord injury, including its structure and histopathological changes. Further, it summarizes the progress of drug therapies targeting the spinal cord microcirculation after spinal cord injury.
