不同超声乳化参数设置对白内障患者眼内影响的研究进展

Zhongshan Daxue xuebao. Yixue kexue ban
白内障是全球范围内致盲的重要原因之一。超声乳化术凭借创伤小、恢复快的优势，已成为治疗白内障的主流手术方式。然而，超声乳化术中参数的设置对眼内组织（尤其是角膜内皮和视网膜）的潜在损伤备受关注。本文系统分析了超声乳化术中3个核心参数（超声频率、灌注瓶高、超声能量）对眼内组织的影响机制及其相互作用。高频超声提高了乳化效率并缩短手术时间，但伴随更显著的热效应，尤其当术中结合高能量输出时，会明显加剧角膜内皮细胞的热损伤风险。高瓶高在维持前房稳定的同时，也增加了机械性剪切应力和湍流，对内皮细胞产生额外的物理损伤 ...

全尺寸高压开关柜电缆绝缘故障电致燃烧试验研究及机理分析

Gaoya dianqi
由于开关柜的封闭特性，长期以来研究人员对于开关柜内火灾发展的时空演变规律缺乏认知，对电缆放电能否引燃、如何燃烧有争议，针对性的防范措施缺乏依据。燃烧试验难度大，全尺寸试验难以开展。文中针对高压开关柜电缆单相接地短路引发火灾的过程开展研究。搭建全尺寸试验平台，研究掌握了电缆短路起火过程中开关柜内外以及电缆外皮的温度分布情况。开展了多物理场仿真研究，构建了开关柜起火模型，掌握了火灾蔓延规律。基于仿真和试验结果对电缆电致燃烧过程中电缆材料分解过程及材料分解对燃烧的影响进行了分析。通过上述研究 ...

内质网应激与急性肺损伤恶化关联性的研究进展

Zhongshan Daxue xuebao. Yixue kexue ban
急性肺损伤（ALI）是一种严重威胁全球人类生命健康的疾病，其主要病理特征为肺泡上皮细胞和肺毛细血管内皮细胞的损伤，导致弥漫性肺间质水肿和肺泡水肿，通常伴有急性低氧性呼吸功能不全。内质网应激（ERS）在ALI的发生和发展过程中扮演着关键角色。它通过多种途径加剧急性肺损伤：在细胞凋亡方面，关键蛋白如GRP78、CHOP和caspase-12参与调控，促进肺血管内皮细胞和肺泡上皮细胞的凋亡，从而加重肺组织损伤；在ROS代谢方面，诱导活性氧（ROS）的大量释放，NADPH氧化酶等参与ROS的产生过程 ...
