Objective To investigate the characteristics of fundus photography and fundus fluorescein angiography of IRVAN (idiopathic retinal vasculitis, aneurysms, and neuroretinitis) syndrome and Eales disease.

目的 观察特发性视网膜血管炎、动脉瘤、视神经视网膜综合征和Eales病荧光素眼底荧光血管造影特征的异同。

Sensory impairment and urinary dysfunction also had developed, and paraparesis persisted after the hypokalemia was corrected during hospitalization. An optokinetic nystagmus test showed bilateral sick waves and at the same time a cerebrospinal fluid analysis was normal. A blood examination disclosed borderline anti-nuclear antibodies and an elevated serum IgG level. Her cervical spinal cord showed mild swelling and contrast-enhancement when examined by magnetic resonance imaging. Neither a brain stem nor an optic nerve's lesion was found. Based on the above, acute transverse myelitis was diagnosed. All the symptoms present in the patient relieved gradually after 5-days of pulsed intravenous methylprednisolone therapy.

一50岁女性，因为眩晕、前额头痛、视力模糊、恶心、呕吐及两侧下肢无力而求诊，於低血钾矫正后，两侧下肢无力依然持续，并发生胸部以下感觉缺损及排尿困难等现象，视运动性眼振检查显示两侧波形障碍，脑脊液检查正常，血液学检查显示抗核酸抗体及血清IgG指数偏高，显影剂增强磁振造影显示颈段脊髓肿大且略为显影，并无脑干或视神经的病灶，诊断为急性横断性脊髓炎，给予静脉注射类固醇后症状逐渐缓解。

巨细胞病毒性视网膜炎是获得性免疫缺陷综合征患者晚期眼部机会性感染，常发生于CD4+ T淋巴细胞计数低于50个/mm3 的患者，可引起进行性全层视网膜坏死、视神经萎缩，最终导致视力丧失。

These NFL and fundoscopic findings suggest that some of the injury seen in NMO may be vascularly mediated.

与多发性硬化患者相比，视神经脊髓炎患者的神经纤维层轴索损伤程度更严重和广泛。

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。
