Results In 36 patients,CT was useful for the diagnosis of fracture,subarachnoid hemorrhage and multiple brain contusions,but missed 2 patients with brain contusion,5 patients with axis cylinders injury and 1 patient with subdural hematoma.MRI was more sensitive compared to CT with a miss of 3 patients with fractures,1 patient with axis cylinder injury and 4 patients with subarachnoid hemorrhage.

结果 36例中，CT对骨折、蛛网膜下腔出血及多发脑挫裂伤显示较好，但漏检2例脑挫裂伤、5例轴索损伤和1例硬膜下血肿；MRI病灶检出率较CT高，但MRI有3例骨折、1例轴索损伤和4例蛛网膜下腔出血不能检出。

Howeer, few studies hae looked at changes of neurons within the caused by disturbance of axonal flow, the axon reaction, chromatolysis, and cell death as a result of mechanical compression of the entral

但是， 很少有研究关注腹侧神经根机械性压迫所致的神经元改变，如轴流，轴索反应，染色质溶解，细胞死亡等。

Pathological examination showed the obvious edema in myelin sheath,axons and perineurium in 2 w group,and disintegrated myelin sheath,degenerated axons and hyperplastic fibrous connective tissues in the other model groups.

病理学观察：卡压2周组神经束内髓鞘、轴索和神经束膜纤维出现明显水肿，余卡压组可见髓鞘崩解、轴索变性，纤维结缔组织增生逐渐明显。

Results there were unconsciousness, respiratory rhythm disturbance and hyporeflexia of pupil light reflex immediately after injury, and reactiveness decrease and activity retardation still existed even after resuming consciousness. at anatomical scene, subarachnoid hemorrhage or cerebroventricular haemorrhage were widespread. at an early stage, there were swelling, collapse, and axonal retraction ball formation at cortico-medulla junction, callosum, brainstem, and cerebellar white matter under microscope. but at the later stage, gitter cell proliferation and nest-like aggregation were major pathophysiological changes at focal brain tissue.

结果 伤后大鼠均即刻出现原发昏迷，其中2只于损伤后20 min内死亡，余持续时间1-30 min不等；伤后大鼠呼吸节律紊乱，瞳孔对光反射减弱或消失，醒后均有程度不等的反应性下降，肢体活动迟缓；肉眼可见广泛蛛网膜下腔出血或脑室出血；光镜下可见皮髓交界区、胼胝体区、脑干、小脑白质等部位的神经轴索有不同程度的肿胀、断裂、轴索球形成，后期有小胶质细胞增生，局部呈巢样聚集。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

In one case of which phrenic nerve was transferred to the musculocutaneous nerve (the nerve graft 8 cm), the biceps showed some nerves regeneration shown in the EMG 15 months postoperatively.

方法采用特制保护液浸泡、液氮冷冻及断面修整、粘合与固定等轴索修复技术，对12例周围神经(13根神经)损伤的患者进行轴索水平的修复，术后平均随访9.7个月。

Many developing axons become myelinated by glial cells; this increase the speed of axonal conduction.

许多生长中的轴索变成有髓鞘的神经胶细胞，他能增加轴索传递的速度。

Non-DAI group also showed decreased NAA/Cr at splenium and increased Cho/Cr at genu of corpus callosum compared with control group (P 0.01), but the change degree was less than DAI group.

与对照组相比，非弥漫性轴索损伤组出现胼胝体膝部胆碱复合物/肌酸和磷酸肌酸升高和压部N-乙酰天冬氨酸/肌酸和磷酸肌酸降低(P 0.01)，但变化程度比弥漫性轴索损伤组低。
