- 急性创伤性脊髓损伤 (SCI) 缺乏经批准的除神经康复之外的干预疗法.
- 对于SCI临床试验来说,最佳的患者分层仍然是一个挑战,因为没有经过验证的生物标志物.
- 神经元功能的电生理学标志物提供了一种潜在的方法,可以比传统的临床措施改进丰富策略.
研究的目的:
- 评估电生理学标记,以提高急性创伤性脊髓损伤 (SCI) 临床试验中的患者分层.
- 根据临床与电生理学标准对比分层的有效性,以预测NG101治疗后的恢复.
- 评估电生理学标记物对统计功率和SCI试验中所需样本大小的影响.
主要方法:
- 在SCI (NISCI) 阶段-2b试验中Nogo抑制的数据的回顾性分析 (NCT03935321).
- 根据临床神经学检查与电生理学记录 (体感唤起潜能 - SSEPs) 进行的急性宫SCI参与者的分层 (n=116).
- 在NG101和安慰剂组之间对上肢运动得分和自我护理独立性的治疗效果大小的比较.
主要成果:
- 临床分层发现,接受NG101治疗的运动不完全参与者与安慰剂 (p=0.007) 相比,功能恢复更大.
- 电生理学分层显示,使用NG101治疗的保存SSEP的参与者与安慰剂治疗的参与者 (p<0.001) 的功能恢复显著增加 (p<0.001).
- 与临床分层 (科恩d=0.46) 相比,对于电生理分层 (科恩d=0.94),效应大小较大,所需的样本大小较小 (Nreq=32对Nreq=120).
结论:
- 与临床测量相比,电生理学标记在急性SCI试验中提供了优越的生物标记驱动的丰富性.
- 利用保存的电生理功能可以提高统计能力,并减少塑性诱导干预试验中的样本大小要求.

Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
