简介:糖尿病视网膜病变(diabeticretinopathy,DR)是糖尿病最严重和最常见的微血管并发症之一,也是一种世界范围内主要的致盲性眼病。其发病机制相当复杂,目前尚未完全明确。经典理论包括多元醇代谢异常、糖基化终产物的形成增加、蛋白激酶C的活化、氧化应激等。近年来,随着分子生物学的发展,分子基础研究已成为目前DR发病机制研究的焦点和热点。目前已知与DR有关的细胞因子有VEGF,IGF-1,bFGF,TNF等。多种细胞因子通过信号转导系统形成复杂的网络系统,引起新生血管生成,破坏血-视网膜屏障等多种改变,从而导致DR的发生发展。本文就细胞因子表达异常与DR的关系进行综述。

简介:目的探讨舒适护理在急性闭角型青光眼手术患者中的应用效果。方法将我科未开展舒适护理模式的2008年3月-2009年12月66例患者设为对照组,已开展舒适护理的2010年3月-2011年11月92例患者设为观察组。对照组给予常规护理和指导,观察组在常规护理的基础上,采用舒适护理方式并评价其效果。结果通过对青光眼患者的舒适护理干预,观察组焦虑状况低于对照组,病人舒适度高于对照组,两组差异有统计学意义(P〈0.05),观察组满意率明显优于对照组(P〈0.01)结论舒适护理可以增加患者的舒适程度,减轻负性情绪,对疾病的治疗、康复起积极作用。同时,有利于增进医患关系的和谐,提高护理满意率。

简介:糖尿病性视网膜病变(diabeticretinopathy,DR)是眼底病中的常见病,也是糖尿病的严重并发症之一。近年来随着对DR发病分子机制的不断研究,人们对DR的认识更进一步,认为聚腺苷二磷酸核糖聚合酶可能是DR发病机制中的关键启动因子,并通过多种相关分子的作用导致DR的发生。本文围绕聚腺苷二磷酸核糖聚合酶及其相关分子在DR中的表达做系统阐述。
