Alzheimer's disease is an age-related neurodegenerative disorder with a complex and incompletely understood pathogenesis. Despite extensive research, a cure for Alzheimer's disease has not yet been found. Oxidative stress mediates excessive oxidative responses, and its involvement in Alzheimer's disease pathogenesis as a primary or secondary pathological event is widely accepted. As a member of the selenium-containing antioxidant enzyme family, glutathione peroxidase 4 reduces esterified phospholipid hydroperoxides to maintain cellular redox homeostasis. With the discovery of ferroptosis, the central role of glutathione peroxidase 4 in anti-lipid peroxidation in several diseases, including Alzheimer's disease, has received widespread attention. Increasing evidence suggests that glutathione peroxidase 4 expression is inhibited in the Alzheimer's disease brain, resulting in oxidative stress, inflammation, ferroptosis, and apoptosis, which are closely associated with pathological damage in Alzheimer's disease. Several therapeutic approaches, such as small molecule drugs, natural plant products, and non-pharmacological treatments, ameliorate pathological damage and cognitive function in Alzheimer's disease by promoting glutathione peroxidase 4 expression and enhancing glutathione peroxidase 4 activity. Therefore, glutathione peroxidase 4 upregulation may be a promising strategy for the treatment of Alzheimer's disease. This review provides an overview of the gene structure, biological functions, and regulatory mechanisms of glutathione peroxidase 4, a discussion on the important role of glutathione peroxidase 4 in pathological events closely related to Alzheimer's disease, and a summary of the advances in small-molecule drugs, natural plant products, and non-pharmacological therapies targeting glutathione peroxidase 4 for the treatment of Alzheimer's disease. Most prior studies on this subject used animal models, and relevant clinical studies are lacking. Future clinica

直观描述超/特高压输电线路的绕击风险分布,展现线路结构、地形地貌、雷电活动等复杂因素的交互关系具有重要的价值,相关研究亟待深化。该文开展了绕击风险评估多源数据融合可视化方法研究。基于输电通道点云数据、EGM模型参数、绕击闪络率等多源数据特征分析,借鉴“以数生智”认知过程,提出了一种数据融合3维可视化框架及关键技术。该方法采用“档距-导线-断面-计算点-暴露弧”层级数据结构,按层级关联整合不同维度表达需求的数据,基于输电通道激光雷达点云空间开展以暴露弧为载体的绕击风险机理可视化,实现绕击闪络率、屏蔽机理、雷电流幅值等多源信息的综合立体展示,通过支持对限定条件的响应,实现了绕击故障分析应用。某500 kV线路档距案例应用结果表明:融合可视化能够发挥3维视图多尺度、多视角的优势,通过暴露弧与点云数据的信息互补,从机理层面揭示避雷线、地面对导线的屏蔽作用,提升数据展示的全面性、直观性。
