The findings demonstrated that tTG is present in PVR epiretinal membranes and cultured human RPE cells. Its amount is stimulated to increase by the PVR vitreous humor. tTG takes part in the process of PVR. It may play an important role in the formation of PVR membranes.

PVR视网膜前膜和培养的人RPE细胞tTG表达阳性，在PVR患者的玻璃体液作用下，RPE细胞的tTG表达水平升高，表明tTG参与了PVR的发病过程，在PVR视网膜前膜的形成过程中可能有重要作用。

BALTIMORE, MD -- December 15, 2006 -- A drug commonly used to slow the loss of central ision has shown promise in stemming a common precursor of blindness in diabetics, which inoles the same central light-sensitie area of retina, Johns Hopkins Wilmer Eye Institute scientists report.

马里兰州，巴尔地摩，2006年12月15日讯据约翰霍普金斯Wilmer眼科研究所的科学家报道，一种目前被广泛用来延缓中心视觉丧失的药物有希望用来防治导致糖尿病患者致盲的视网膜早期病变，该病变也发生在视网膜中心的光敏区。

Creating chorioretinal venous anastomosis potentially offers a means of permanently bypassing the site of obstruction to venous outflow, to recovery the retinal blood circulation and to reduce the retinal ischemia.

为此本研究的目的是在视网膜静脉阻塞模型眼中，用不同的方法建立视网膜静脉和脉络膜的吻合，比较其疗效和安全性，并作初步的临床治疗探索。

The objectives of this study were to elucidate the normal stage of connectional development in human visual pathway so that the effects of the abnormal connection in human might be understood.

包括视网膜输出至外侧膝状体的M细胞和P细胞；视交叉的发育；膝距束终末内生长至初级视皮质；视网膜投射至顶盖前核和上丘通路的发育过程，提供胚胎中枢视觉通路连续动态形态学超微结构内容，动态观察发育性结构与人类视觉功能之间的关系。

The expression of ILK in the preretinal membranes in PDR indicate that ILK involves in the pathological process of neovascularization in PDR. Intravitreal injection of Avastin can decrease the numbers of endothelial cells in the proliferative fibrovascular membranes, and it also can down-regulate the expression of VEGF and HIF-1αprotein, but it can not affect the expression of ILK protein.

结论1。人PDR增殖膜中的新生血管有ILK表达，提示ILK参与了视网膜新生血管的形成过程；玻璃体内注射Avastin治疗PDR，能够减少视网膜新生血管内皮细胞数量，下调HIF-1α、VEGF在增殖膜的表达，但不能下调ILK的表达。

BACKGROUND: Retinitis pigmentosa is a group of commonest genetic blindness-inducing eyeground diseases, which have relative great heterogenicity in both heredity and phenotype. Pierce et al discovered a new retinal photoreceptor cell specific gene-RP1 in 1999, and also found in their following research that the mutation of this gene can induce autosomal dominant RP .

背景：视网膜色素变性(retinitis pigmentosa，RP)是一组最常见的遗传性致盲眼底病，在遗传和表型上均具有较大的异质性。1999年Pierce等发现了一个新的视网膜感光细胞特异基因--RP1，之后的研究发现该基因的突变可导致常染色体显性遗传RP(autosomal dominant RP，adRP)。

In recent years,some progresses have been achieved on the prevention of apoptosis of retinal cells. In the field of ophthalmologic clinical and basic reserch,it is important to explore the use of anti-apopototic approaches as novel preventive and therap...

近年来在防止视网膜细胞凋亡方面已经取得了一些可喜的进展，但如何从抗凋亡的角度来探索预防和治疗视网膜退行性变性疾病的新途径，仍是今后眼科应用基础研究的重点。

Objective To study the wave form of the photopic negative response in electroretiongram, and the relationship between PhNR and retina nerve fibre layer thickness, visual field mean defect, and cup/disc ratio. Investigate the function of PhNR in diagnosis of traumatic ocular nerve atrophy and evaluation of ocular nerve ganglion cells.

目的 研究外伤性视神经萎缩的视网膜电图各成分及其明视负向反应的变化特点，并进行PhNR与视网膜神经纤维层厚度、视野平均缺损值，以及杯盘比的相关性研究，探索在外伤性视神经萎缩中PhNR的变化规律。

Objective To study the effects of subretinal fluid on the proliferation of retinal pigment epithelium cells and on the activation and translocation of protein kinase C; to investigate the relationship between the proliferation and the changes of PKC in the RPE cells; and to study the effect of PKC inhibitor.

目的 探讨视网膜下液能否引起体外培养的视网膜色素上皮细胞增殖及在其增殖过程中是否出现蛋白激酶C的激活和转位，进一步明确RPE细胞增殖与RPE细胞中PKC信号系统变化的关系及PKC抑制剂的作用。

It required spiking of postsynaptic tectal cells as well as activation of NMDA receptors, and effectively occluded long-term potentiation of retinotectal synapses induced by direct electrical stimulation of retinal ganglion cells.

这需要突触后顶盖细胞的脉冲和NMDA受体活化，并有效闭塞连接视网膜和中脑顶盖神经纤维的突触长期的增强，这是由视网膜活动中心细胞的直接电激诱发的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
