摘要:
目的：探讨房水中色素上皮衍生因子(pigment epithelium derived factor, PEDF)与视网膜电图振荡电位(oscillatory potentials, OPs)在各期糖尿病性视网膜病变中的相关性研究分析，为糖尿病视网膜病变(diabetic retinopathy, DR)的早期诊断及病程进展预测提供客观的检测依据。方法：房水来自2型糖尿病患者40例40眼。单纯2型糖尿病患者组19例19只眼，非增殖期糖尿病性视网膜病变(non-proliferative diabetic retinopathy, NPDR)组患者11例11只眼，增殖期糖尿病视网膜病变(proliferative diabetic retinopathy, PDR)组患者10例10只眼，单纯老年性白内障患者20例20只眼作为对照组。用酶联免疫吸附法检測房水中PEDF的水平，用德国 ROLAND CONSULT公司生产的罗兰视觉电生理检查仪检测全视网膜电图中OPs的总振幅值。结果：单纯2型糖尿病患者组、NPDR组及PDR组的房水中PEDF的浓度分别为(9.13 ± 4.43) ng/ml、(7.00 ± 2.04) ng/ml、(6.39 ± 1.66) ng/ml与对照组(13.87 ± 0.36) ng/ml相比，房水中PEDF浓度均明显降低(P
Objective: To investigate the relationship between pigment epithelium derived factor (PEDF) and oscillatory potentials (OPs) in various diabetic retinopathy and to provide an objective basis for the early diagnosis of diabetic retinopathy (diabetic retinopathy, DR) and the prediction of the progression of the disease. Methods: Aqueous humor samples were collected from 40 eyes of 40 type 2 diabetes patients, including 19 eyes without diabetic retinopathy and 21 eyes with diabetic (11 eyes with NPDR and 10 eyes with PDR), twenty aqueous samples from 20 cataract patients without other ocular or systemic diseases served as controls. The PEDF levels in aqueous humor were measured by enzyme-linked immunosorbent assay (ELISA). The total amplitude of OPs in the whole retina was detected by the Roland visual electrophysiological test instrument of the German CONSULT ROLAND company. Results: The PEDF and OPs level in eyes without diabetic retinopathy [(9.13 ± 4.43) ng/ml, 164.56 ± 37.41) μV, P
