概括

退行性宫髓病 (DCM) 损害脊髓功能,通常是由于诊断延迟. 血脊髓屏障 (BSCB) 的破坏会使手术后的结果和恢复情况恶化.

科学领域:

神经学神经学
神经外科神经外科
病理生理学病理生理学

背景情况:

退行性宫髓病 (DCM) 是老年人脊髓功能障碍的主要原因.
延迟诊断和治疗可能会导致严重的,不可逆转的神经系统缺陷.
当前对DCM病理生理学的理解往往忽视了血脊髓屏障 (BSCB) 的作用.

研究的目的:

审查DCM的病理生理学,重点关注BSCB中断的关键作用.
突出BSCB妥协如何影响神经预后和手术减压后的恢复.
探索针对BSCB复制的潜在治疗策略.

主要方法:

对DCM病理生理学现有文献的审查.
对DCM患者中BSCB妥协的临床证据分析 (中枢神经流蛋白比率,MRI发现).
检查前临床动物模型,证明BSCB变化和神经血管单元病理.

主要成果:

BSCB中断是DCM的一个关键病理特征,由CSF/血清蛋白质升高和MRI对比度增强证明.
动物模型显示DCM中血管透性增加和神经血管单元损伤.
在DCM手术减压后,BSCB功能障碍与缺血-再输液损伤有关.

结论:

在退行性宫骨髓病症中,BSCB完整性对神经恢复至关重要.
针对BSCB复制剂提供了一个潜在的治疗途径,以改善DCM患者的治疗结果.
对BSCB修复疗法的进一步研究是有必要的,以减轻神经系统的后果.

关键词:

Spinal Cord: Gross Anatomy

Spinal Cord: Gross Anatomy

The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

The Spinal Cord

The Spinal Cord

The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
