目的通过观察糖基化终末产物(advanced glycation end products,AGE)对体外培养牛眼小梁细胞凋亡的影响,研究AGE与原发性开角型青光眼(primary open angle glaucoma,POAG)之间的关系,进一步探讨其发病机制。方法体外培养牛眼小梁细胞,通过形态学观察和神经元特异性烯醇化酶染色对培养的细胞进行鉴定。将第3代小梁细胞接种于6孔培养板,在培养基中加入不同浓度(0μg·mL-1、50μg·mL-1、100μg·mL-1、200μg·mL-1)的AGE-BSA培养96 h。终浓度(200μg·mL-1)的AGE-BSA培养液处理细胞不同时间(48 h、72 h、96h)。应用流式细胞仪检测小梁细胞凋亡率;活性氧荧光探针2’,7’-二氯荧光黄双乙酸盐检测细胞内活性氧(ROS)水平。结果 50μg·mL-1、100μg·mL-1、200μg·mL-1AGE-BSA作用96h后细胞凋亡率分别为(5.60±0.25)%、(9.57±0.08)%、(17.68±0.21)%,与对照组(0μg·mL-1AGE-BSA)细胞凋亡率(4.45±0.12)%相比均明显增高,且差异均...

Objective To investigate the effects of advanced glycation end products( AGE)on apoptosis of bovine trabecular meshwork cells( TM cells) cultured in vitro,and further explore the relationship between AGE and primary open angle glaucoma( POAG),probe its pathogenesis. Methods The bovine TM cells were cultured in vitro and identified by morphological evaluation and neuronspecific enolase staining. The third generation of cells were inoculated to 6-well plate,and different concentrations( 0 μg·mL- 1,50 μg·mL- 1...

原发性开角型青光眼(primary open angle glau-coma,POAG)是一种常见致盲性眼病,大型流行病学
研究显示糖尿病为POAG最常见的病因,与POAG发病率呈正相关[1]。糖尿病患者中POAG的发病率为
4%~11%[2],比一般人群(2%)高。糖尿病与POAG间的关系密切,但糖尿病患者并发POAG的发病
