目的:评价患有颅内动脉瘤(intracranial aneurysm,ICA)的眼底表现,以明确ICA和可辨别的视网膜改变的关系。方法:共分析了46位已经在神经外科诊断颅内动脉瘤患者的病历和眼部检查图像。所有的患者接受了包括荧光血管造影(fluorescein angiography,FAG)在内的眼科检查。此外,玻璃膜疣、黄斑变性、棉绒斑、硬性渗出、视网膜出血、动脉变细、动-静脉交叉征、臂-视网膜循环时间、动-静脉循环时间都进行了分析。ICA患者(组1)的检查结果和22例特发性视网膜前膜患者未患病眼(组2)的结果进行了比较。结果:两组患者的平均年龄分别为60.02岁(组1)和60.68岁(组2)(P=0.70)。高血压的患病率在两组中相似。两组中均未发现患视网膜大动脉瘤的患者。两组之间玻璃膜疣、黄斑变性、棉绒斑、硬性渗出、视网膜出血、动脉变细和动-静脉交叉征的情况无显著差异。平均臂-视网膜循环时间也未发现显著差异。结论:我们未发现有任何证据证明ICA患者FAG检查和眼底有特殊改变。

Tanycytes, specialized ependymal cells located in the hypothalamus, play a crucial role in the generation of new neurons that contribute to the neural circuits responsible for regulating the systemic energy balance. The precise coordination of the gene networks controlling neurogenesis in naive and mature tanycytes is essential for maintaining homeostasis in adulthood. However, our understanding of the molecular mechanisms and signaling pathways that govern the proliferation and differentiation of tanycytes into neurons remains limited. This article aims to review the recent advancements in research into the mechanisms and functions of tanycyte-derived neurogenesis. Studies employing lineage-tracing techniques have revealed that the neurogenesis specifically originating from tanycytes in the hypothalamus has a compensatory role in neuronal loss and helps maintain energy homeostasis during metabolic diseases. Intriguingly,metabolic disorders are considered early biomarkers of Alzheimer's disease. Furthermore,the neurogenic potential of tanycytes and the state of newborn neurons derived from tanycytes heavily depend on the maintenance of mild microenvironments, which may be disrupted in Alzheimer's disease due to the impaired blood–brain barrier ***, the specific alterations and regulatory mechanisms governing tanycyte-derived neurogenesis in Alzheimer's disease remain unclear. Accumulating evidence suggests that tanycyte-derived neurogenesis might be impaired in Alzheimer's disease, exacerbating neurodegeneration. Confirming this hypothesis, however, poses a challenge because of the lack of long-term tracing and nucleus-specific analyses of newborn neurons in the hypothalamus of patients with Alzheimer's disease. Further research into the molecular mechanisms underlying tanycyte-derived neurogenesis holds promise for identifying small molecules capable of restoring tanycyte proliferation in neurodegenerative diseases. This line of investigation could pro

The BLU (back light unit) is the core component of the LCD for notebook, mobile-phone, navigation, as well as large sized TV, PID (public information display), etc. In order to enhance optical efficiency of LCD, optical films with the uniform prism patterns have been used for BLU by stacking two films up orthogonally. In this case, light interference-phenomenon occurred such as Morie, wet-out, u-turning, etc. It caused several problems such as low brightness, spots and stripes in LCD. Recently, the high-luminance micro complex prism patterns are actively studied to avoid the light interference-phenomenon and enhance the optical efficiency. In this study, the roll master to manufacture complex micro prism pattern film was machined by using the high precision lathe. The machined patterns on the roll master were 50, 45, 40, 35, 30, 25, 20, 15, 10 and 5 μm in the pitch with 25.0, 22.5, 20.0, 17.5, 15.0, 12.5, 10.0, 7.5, 5.0 and 2.5 μm in the peak height, respectively. The roll was 2 000 mm in length and 320 mm in diameter. The electroplated roll by copper and the natural single crystal diamond tool was used for machining the patterns. The cutting force was measured and analyzed for each cutting condition by using the dynamometer. The chips and the surfaces after being machined were analyzed by SEM and microscope.

Oxide semiconductor SrTiO3 single crystals are exposed to a reducing atmosphere H2/N2 to induce the reduction of Ti4＋ to Ti3＋ and the release of oxygen from the lattice compensating the reduction of the Ti ions. In a reducing atmosphere H2/N2 the optical edge brings about a red shift. The infrared reflection spectra suggest that the （11） STO single crystal surface can be terminated by the domain of the SrO or TiO2 alternative layer during the reduction. The anisotropy and asymmetry of optical second-harmonic intensity explain a slight shrinkage. The dielectric constant reaches about 6000 and shows almost frequency dependence at all temperatures. With the increasing temperature, the dielectric constant increases rapidly. The high temperature region and low temperature region have activation energies of 0.89 and 1.04, respectively.
