简介：当你在工作的时候一定要注意学会自我保护,防止在工作中受伤。这不仅仅是说让自己不在一时收到伤害,更是要注意不要让这种身体的损伤伴随你以后的生活。工作中造成的身体劳损会使你在以后得工作中能力下降,这就意味着你不能再在用同等的收入来维持你的家庭支出。因此你应当尽量在工作环境中保护自己避免受到工伤,时刻注意保护自己,时刻提醒自己安全第一。每个人都有责任保护自己和他人的安全,万万不可在安全方面耍滑头,

简介：目的探讨自我管理项目在门诊青光眼患者中的应用及效果。方法将112例门诊青光眼患者随机分为56例对照组、56例干预组。对照组给予门诊常规药物治疗和常规健康教育指导;干预组在门诊常规药物治疗基础上,进行自我管理项目干预,比较两组病人的自我管理行为、自我效能水平和生活质量。结果干预后12周,干预组自我管理行为、自我效能水平和生活质量显著优于对照组（P〈0.05）。结论自我管理项目干预能提高青光眼患者自我管理行为、自我效能水平和生活质量。

简介：目的提升我科住院患者眼药应用知识及行为的知晓率,提高我科住院患者满意度。方法成立QCC小组,运用品管圈活动的管理方法对我科住院患者眼药应用知识及行为的掌握率低进行原因分析、现状调查、设立目标、制定对策并组织实施。结果通过对开展QCC活动前后的调查结果进行分析,住院患者的眼药应用知识及行为掌握率由原来的40%提升到80%,目标达成率为140%。结论通过品管圈活动的开展,利用先进的管理方法,护士有针对性地对患者进行形式多样的健康宣教,使眼科住院患者能正确掌握眼药应用知识及行为,安全地使用眼药,保证患者身体健康。提高了我科住院患者的满意度,延伸护理服务内容,塑造了优质护理服务的良好形象,激活了护士的学习和工作积极性,并提高了分析问题、解决问题能力及团队合作精神。

简介：目的探讨电话回访、微信等方式对闭角型青光眼患者出院后进行延伸护理服务,以提高患者遵医行为和改善护患关系的影响。方法将160例闭角型青光眼患者随机分为对照组和观察组各80例,对观察组患者于出院后第一周开始电话回访,以后分别于两周、一月、三月、六月、一年回访。对照组采用常规方法。一年后对2组患者遵医行为和再入院人数及满意度进行评价。结果观察组患者在随访期间遵医行为人数及满意度调查,明显好于对照组,再入院人数明显少于对照组（P〈0.01）。结论延伸护理服务有利于患者掌握闭角型青光眼相关的健康教育知识,增强患者遵医行为,调动患者的主观能动性,对延缓病情进展、预防并发症、减少再入院次数、减轻经济负担、提高生活质量起到了促进作用。

简介：对于原发性开角型青光眼（POAG），治疗的基本原则是通过药物、手术或激光等方式降低眼压，但是患者的日常生活习惯对治疗后眼压的控制、病情的缓解有着不可忽视的影响。日常生活中影响眼压和POAG病情发展的相关因素主要有饮酒、吸烟、运动、肥胖和饮用咖啡、茶等。本文主要就流行病学调查方面研究结果，进行了分析总结，提出在日常生活方面的注意事项，给眼科医生提供相关信息，给患者提供生活指导。

简介：目的：研究在高糖诱导人晶状体上皮细胞向间充质转化的过程中JAK-STAT通路的作用及AG490对此过程的影响。方法：低糖（5.5mmol/L）DMEM培养液体外培养人晶状体上皮细胞系SRA01/04。高糖（30.5mmol/L）处理细胞,按照是否加入AG490及其浓度的不同分为实验组和对照组。CCK-8试剂盒检测晶状体上皮细胞的活性,选择实验组AG490浓度为10μmol/L和50μmol/L,处理时间分别为6,12,24和48h；细胞划痕实验检测细胞迁移能力的变化；RT-PCR方法半定量检测TGF-β1,FN和α-SMA的mRNA表达量变化。结果：在不同的处理时间（6,12,24,48h）,高糖组（HG组）与低糖组相比,细胞的迁移能力增加（P〈0.05）,TGF-β1,FN和α-SMA表达量增高（P〈0.05）；AG490组与HG组相比,细胞的迁移能力降低（P〈0.05）,TGF-β1,FN和α-SMA的mRNA表达量下降。结论：JAK-STAT通路通过影响TGF-β1和细胞外基质转录表达参与了高糖诱导的人晶状体上皮细胞向间充质转化的过程。JAK抑制剂AG490对此过程有抑制作用,且随着AG490浓度的增加其抑制作用增强。
