简介：目的：探讨术前注射曲安奈德（TA）联合25G微创玻璃体视网膜手术（vitreoretinalsurgery，VRS）治疗增生型糖尿病性视网膜病变（proliferativediabeticretinopathy，PDR）的效果。方法：选取我院眼科需行VRS治疗的PDR患者108例108眼随机分为两组，VRS＋TA组：VRS术前1wk行玻璃体腔注射TA的患者54例；VRS组：直接行VRS治疗患者54例，比较两组患者手术情况、术前、术后3mo裸眼视力、最佳矫正视力，术前、术后1wk，1、3mo眼压和并发症情况。结果：VRS＋TA组手术时间、电凝率、医源性裂孔率和术中出血率显著短于或低于VRS组，差异有统计学意义（P〈0.05），而两组患者眼内填充物比较无统计学差异（P〉0.05）；两组患者术后3mo裸眼视力和最佳矫正视力较术前均得到显著提高，差异有统计学意义（P〈0.05），两组间比较差异无统计学意义（P〉0.05）；VRS＋TA组术后1、3mo眼压较术前显著升高，差异有统计学意义（P〈0.05），两组间比较差异无统计学意义（P〉0.05）；VRS＋TA组前房渗出率显著低于VRS组，差异有统计学意义（P〈0.05），但两组并发症总发生率差异无统计学意义（P〉0.05）。结论：PDR患者行VRS治疗前1wk注射TA，可降低手术难度，缩短手术时间，并减少术中、术后并发症，利于患者术后视力改善。

简介：目的观察1,25（OH）2D3对高糖诱导牛视网膜血管内皮细胞（BRECs）中血管内皮生长因子（VEGF）的表达水平变化及对细胞凋亡水平的影响。方法将分离培养的BRECs分为三组,分别为正常糖组、高糖组和高糖处理组。正常对照组细胞培养液含5mmol/L葡萄糖,高糖组细胞培养液含30mmol/L葡萄糖,高糖处理组细胞培养液含30mmol/L葡萄糖和50nM,1,25（OH）2D3。培养48h后收集细胞蛋白。蛋白免疫印迹法检测细胞VEGF及细胞凋亡相关蛋白Bax和Bcl-2表达水平;PI/Hoechst双染色法检测细胞凋亡。结果相比于正常糖组,高糖组中VEFG水平和Bax/Bcl-2比值显著增加;而在高糖处理组中表达水平远远低于高糖组,差异均有统计学意义（P〈0.05）。高糖的细胞凋亡水平高于正常糖组,而经过1,25（OH）2D3处理后,其细胞凋亡水平则有所下降,差异均有统计学意义（P〈0.05）。结论1,25（OH）2D3可以抑制高糖诱导BRECs中VEGF表达增加及细胞凋亡。
