视神经炎

This is the first reported case of PAN due to hepatitis C with early findings of choroidal and optic nerve infarction.

这是首例以脉络膜和视神经梗塞为早期表现的丙肝病毒致结节性多动脉炎的病例报道。

Interpretation NMO-IgG is a specific marker autoantibody of neuromyelitis optica and binds at or near the blood-brain barrier.

NMO-IgG抗体为视神经脊髓炎的特异性自身抗体标志物，在血脑屏障或血脑屏障附近结合。

Of 14 seropositie cases identified incidentally, 12 had neuromyelitis optica or a high-risk syndrome for the disease.

高危综合征患者约有一半可检出NMO-IgG抗体。14例血清抗体阳性者，其中12例为视神经脊髓炎或高危患者。

We tested masked serum samples from 102 North American patients with neuromyelitis optica or with syndromes that suggest high risk of the disorder, and 12 Japanese patients with optic-spinal multiple sclerosis.

共检测了102例北美视神经脊髓炎或疑似本病患者和12例日本患者的血清标本。

The comparatively low positive rate of CSF-restricted OCB in China may due to the comparatively high incidence of optic neuromyelitis.

MS患者CSF OCB阳性率较低与国内视神经脊髓炎所占比率较高有关；CSF OCB的出现受到MS活动性的影响；也和MS病程演变阶段性相关；激素等免疫抑制剂的作用可能参与其中。

The results were compared among 4 groups. Results:①OCB positive rate was 37% in MS patients, which was lower than other reports, 24% in central nervous system infectious diseases group,5% in central nervous system non-infectious diseases group and 0 in peripheral nervous system diseases group,respectively.②OCB positive rate in conventional MS was 56%, which was higher than that in neuromyelitis optica.

结果①多发性硬化组OCB阳性率为37%，中枢神经系统感染组为24%，中枢神经系统非感染性疾病组为5%，外周神经系统疾病组为0；多发性硬化组的OCB阳性率比其他各组高，但低于国外报道的阳性率；②多发性硬化患者中传统型多发性硬化组OCB阳性率为56%，高于视神经脊髓炎组的11%。

Objective To investigate the pathogenesis of the abnormal diffusion in the white matter tracts in patients with neuromyelitis optica using diffusion tensor imaging.

在视神经脊髓炎(neuromyelitis optica，NMO)患者，脑白质纤维束的扩散异常已有报道，但其分布模式及发生机制尚不清楚[1]。

Objective To investigate the presence of occult brain tissue damage in patients with relapsing neuromyelitis opticaand its possible mechanism by using diffusion tensor imaging.

目的利用扩散张量成像探讨复发性视神经脊髓炎患者是否存在隐匿性脑组织损伤及其发生机制。

Investigation showed aquaporin-4 played an important role in humoral-mediated immunologic mechanism of neuromyelitis optica.Meanwhile,NMO revealed an autoimmune channel disease,and the study on the immunopathogenesis of NMO was ushered into a new stage.

目前研究发现AQP4还参与视神经脊髓炎的体液免疫机制，揭示了NMO是一种自身免疫性通道病，这一发现使NMO的免疫和病理学研究进入了一个新的阶段。

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。
