Objective To study the expression pattern of RYK in the pathway of developmental corticospinal tract projection and provide hints for further study on RYK's function involved in this processes.

目的 观察RYK在皮质脊髓束发育投射通路中的表达情况，为进一步研究RYK在其中的功能提供重要线索。

Objective: To explore the effect of manganese-enhanced magnetic resonance imaging and the fluorescent-tracer DiI on tracing rat corticospinal tract.

目的：验证Mn(上标 2+)增强磁共振技术与DiI荧光示踪技术对于大鼠皮质脊髓束的追踪效果，并对两种方法进行比较评价。

High signal intensity in the lateral part, which corresponded to the lateral corticospinal tract of the cervical spinal cord was seen on T2 weighted images in 7 patients (cases 1, 2, 4, 6 and 11-13)(Fig.3 b).

在所有21例ALS患者中有7例患者（病例1、2、4、6、11~13）在T2像上于颈髓的皮质脊髓侧束区可见高信号病灶。

Combining spatial facilitation with a TES protocol improved monitoring of corticospinal motor pathways during spinal surgery in children.

经颅电刺激联合空间易化可改进儿童脊柱手术中对皮质脊髓运动通路的监测。

Of the other 16 patients with ALS whose upper motor neurone signs were not so manifest (cases 6-21), high signal was seen in the corticospinal tract on T2-weighted images was seen in 11 (cases 6-12, 16-18 and 21); five (cases 6, 7, 11, 12 and 16) of these also showed high signal on the PD-weighted images.

另外16例ALS患者（病例6~21）上运动神经元症状体征不明显，在T2像上有11例可见皮质脊髓束高信号病灶（病例6~12、16~18、21）；在PdWI像上有5例也可见高信号病灶（病例6、7、11、12、16）。

Further study is required to establish whether the high signal intensity in the intracranial corticospinal tract on T1 weighted images correlates with the severity of the upper motor neurone

但，仍需要进一步研究以明确T1像上颅内皮质脊髓束的高信号改变是否与上运动神经元病灶的严重性相关。

The findings suggest that examining the corticospinal tract of the brain and spinal cord with conventional T1-, PD- and T2-weighted images, and also serially, may be useful in the diagnosis of ALS.

我们的研究显示：对ALS患者的脑部、脊髓的皮质脊髓束走行区行常规T1、T2、PdWI像扫描，并在疾病进展过程中行动态连续性观察，有助于ALS的诊断。

Combining spatial facilitation with a TES protocol improed monitoring of corticospinal motor pathways during spinal surgery in children.

经颅电刺激联合空间易化可改进儿童脊柱手术中对皮质脊髓运动通路的监测。

High signal on T1 weighted images in the intracranial corticospinal tract may be specific for ALS and may correlate with the severity of the upper motor neurone lesions.

T1像上颅内皮质脊髓束的高信号改变对ALS而言可能具有特异性，并可能与上运动神经元症状体征的严重程度存在关联性。

DTI technique can clearly display the compression,breaks and destruction of condition of corticospinal tracts;there is close relationship between locations and sizes of specific impairment and rehabilitation level and mechanism of nerve function.

DTI技术可以清晰显示皮质脊髓束等神经纤维受压、中断和破坏的情况，病损具体部位、大小与临床症状和神经功能的恢复程度和恢复机制密切相关，可以用以了解患者的病损信息、指导康复治疗、推测预后等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
