Objective: To determine the death models of neural cells in the spinal cord after compression injury.
目的：观察实验性脊髓损伤后神经细胞死亡方式。
BACKGROUND: Prognosis is determined by degrees of outside force and time of spinal cord compression after spinal cord injury.
背景：脊髓损伤后决定预后的两个主要因素为损伤当时外力的大小和脊髓受压的时间。
The compression index could reflect the nature of spinal cord injury better than size of disc protrusion.
脊髓受压指数比间盘突出大小更能反映脊髓受损的实质。
Spinal cord injury models were established by compression method in rats of model control group and stem cell transplantation group.
模型对照组、干细胞移植组大鼠采用重物压迫法建立脊髓损伤模型。
Results There were obvious specific manifestations on bone structure destruction, compression of spinal cord, hemorrhage and ligament injury during CT and MRI detection.
结果CT与MRI在检查颈段脊柱损伤时，骨结构破坏、脊髓受压、出血和韧带损伤，均能明确显示其特异性表现。
Objective To observed the recovery process of spinal cord motor function after the injury by compression with a water balloon from ventral aspect.
目的观察脊髓腹侧压迫致伤后脊髓功能变化的规律。
Conclusion Continued compression aggravates pathologic injury through affecting the recovery of local spinal cord blood flow.
结论脊髓损伤后持续性压迫使损伤脊髓血流量恢复减慢，病理损害加重。
Conclusion Continued compression aggravates pathologic injury through affecting the recovery of local spinal cord blood flow.
结论脊髓损伤后持续性压迫使损伤脊髓血流量恢复减慢，病理损害加重。
