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：青光眼以进行性视网膜神经节细胞（RGCs）的丢失及其轴突变性为特征，其临床表现为典型的视神经萎缩和视野缺损。因此，延缓或阻止RGCs凋亡的神经保护性措施应作为主要治疗手段。本文通过补充神经营养因子，调控线粒体功能，抑制细胞凋亡通路和毒性作用等几个层面，对基因治疗在RGCs抗凋亡和促进存活作用的最新研究进展进行综述。

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。
