摘要：

目的：探讨血管内皮生长因子（VEGF）、血管细胞间黏附分子（ICAM-1）与增殖型糖尿病视网膜病变的相关性及联合诊断价值。方法：回顾性研究2017年4月至2020年4月于本院确诊糖尿病视网膜病变153例。72例为增殖型糖尿病视网膜病变患者，将其纳入观察组；81例为非增殖型糖尿病视网膜病变患者，纳入对照组。采用流式细胞仪对血管内皮细胞（CEC）进行分型测定，采用酶联免疫吸附法测定VEGF、ICAM-1，并比较组间的差异性与相关性，应用ROC曲线测定其联合诊断效能。结果：观察组CEC含量显著高于对照组（P<0.05）；观察组循环祖细胞（CPC）含量显著低于对照组（P<0.05）；观察组VEGF、ICAM-1水平显著高于对照组（P<0.05）。相关性分析可知VEGF与ICAM-1呈显著的正相关关系（r=0.732，P=0.011），VEGF与CEC呈显著的正相关关系（r=0.684，P=0.023），VEGF与CPC呈显著的负相关关系（r=-0.622，P=0.041）。VEGF的曲线下面积（AUC）为0.844，特异度为85.32%，灵敏度为82.16%；ICAM-1的AUC为0.821，特异度为83.74%，灵敏度为80.21%；联合诊断的AUC为0.914，特异度为88.92%，灵敏度为92.25%。结论：VEGF、ICAM-1与增殖型糖尿病视网膜病变呈显著的同向变化关系，即VEGF、ICAM-1随着病变进展而升高，并且有较好的联合诊断效能。

Objective: To investigate the correlation between vascular endothelial growth factor(VEGF), vascular intercellular adhesion molecule-1(ICAM-1) and proliferative diabetic retinopathy and their combined diagnostic value.Methods: 153 cases of diabetic retinopathy diagnosed in our hospital from April 2017 to April 2020 were retrospectively studied. 72 patients with proliferative diabetic retinopathy were included in the observation group; 81 patients with non proliferative diabetic retinopathy were included in the control group. Flow cytometry was used to determine the type of vascular endothelial cells, and enzyme-linked immunosorbent assay was used to detect VEGF and ICAM-1. The difference and correlation between the two groups were compared, and ROC curve was used to determine the combined diagnostic efficiency.Results: The content of circulating endothelial cells(CEC) in the observation group was significantly higher than that in the control group(P<0.05); the content of circulating progenitor cells(CPC) in the observation group was significantly lower than that in the control group(P<0.05); the levels of VEGF and ICAM-1 in the observation group were significantly higher than those in the control group(P<0.05). There was a significantly positive correlation between VEGF and ICAM-1(r=0.732, P=0.011), there was a significantly positive correlation between VEGF and CEC(r=0.684, P=0.023, there was a significantly negative correlation between VEGF and CPC(r=-0.622, P=0.041). The area under the curve(AUC) of VEGF was 0.844, specificity was 85.32%, sensitivity was 82.16%; AUC of ICAM-1 was 0.821, specificity was 83.74%, sensitivity was 80.21%; AUC of joint diagnosis was 0.914, specificity was 88.92%, sensitivity was 92.25%.Conclusion: VEGF and ICAM-1 have a significant co-directional change relantionship with proliferative diabetic retinopathy, that is, VEGF and ICAM-1 increase with the disease, and have good joint diagnostic efficacy.
