目的：研究缺氧诱导因子-1(hypoxia inducible factor-1，HIF-1)信号通路在高眼压状态下的表达情况。方法：利用前房注射磁性微球法建立大鼠高眼压动物模型，通过荧光金逆行标记观察视网膜神经节细胞(retinal ganglion cells，RGCs)的存活情况，提取视网膜组织行Western印迹检测HIF-1α、血管内皮生长因子-A(vascular endothelial growth factor A，VEGF-A)-和促红细胞生成素

(erythropoietin，EPO)的表达，并分析HIF-1α的变化趋势与眼压之间的关系。结果：高眼压1 d时平均眼压为(40.33±2.94) mmHg，第3天为(68.83±2.85) mmHg，第10天时下降至(43.67±3.67) mmHg，后趋于稳定，与对照眼相比差异均有统计学意义(P<0.01)。高眼压2周时中央、中间和周边视网膜的RGCs存活率分别为61.1%±1.1%，68.5%±8.5%和73.6±3.6%，至高眼压3周迅速下降，分别为33.2%±3.2%，43.4%±3.4%和51.4%±2.1%。高眼压3 d时，眼压值达最高，HIF-1α，VEGF-A和EPO的表达亦达高峰，与对照组相比差异均有统计学意义(P<0.01)；后随着眼压值下降，表达也随之逐渐减少。眼压升高3 d，7 d，2周分别与对照组的HIF-1α/GAPDH的蛋白灰度比和眼压值间的相关系数为0.977，0.886，0.763，差异具有统计学意义(P<0.01)。结论：HIF-1α的表达在一定条件下与眼压值呈正相关，该通路的早期激活可能在高眼压病程中扮演重要的角色。

Objective: To evaluate the expression of hypoxia inducible factor-1 (HIF-1) signaling pathway in the state of intraocular hypertension. Methods: We established an intraocular hypertension model of BN rats model of BN rats through the injection of magnetic microspheres into anterior chamber angle, and then evaluated this  model by measuring the survival rates of retinal ganglion cells (RGCs) through retrograde Fluorogold labelling. Western blot was used to detect the protein expression of HIF-1α, vascular endothelial growth factor A (VEGF-A) and erythropoietin (EPO) in the retinal tissue, and HIF-1α protein’s alterable trend as well as its relationship with intraocular pressure (IOP) was analyzed. Results: The IOP was (40.33±2.94) mmHg at the ffrst day affer elevation, (68.83±2.85) mmHg at the third day, and (43.67±2.94) mmHg at the tenth day, then kept stable later. TTe survival rates of RGCs among central, middle and peripheral retina decreased from 61.1%±1.6%, 68.5%±2.0%, 73.6%±1.5%, at the second week to 33.2%±1.8%, 43.4%±2.4%, 51.4%±2.1% at the third week, the differences were statistically signiffcant (P<0.01). The protein expression of HIF-1α, VEGF-A and EPO reached the peak at the third day when the IOP was at the highest level, then decreased with the drop of IOP. The correlation coefffcient between the protein gray value of HIF-1α/GAPDH and IOP among the 3rd day, 7th day, 2 weeks and the control was 0.977, 0.886, 0.763 respectively (P<0.01). Conclusion: The expression of HIF-1α had a positive relationship with IOP in certain condition, and the early activation of HIF-1 signaling pathway might play an important role in the process of glaucoma.
