摘要 糖尿病血管并发症( diabetic vascular complica-tions,DVC)是糖尿病致残和高致死率的重要原因。临床研究表明严格控制糖尿病患者血糖和血压能够降低糖尿病血管并发症(DVC)发生的风险。由于各种原因,临床上很难做到血糖和血压的严格控制,目前临床上对DVC的防治仍不理想。70%的2型糖尿病患者死于心血管疾病,且糖尿病致终末期肾病与继发性失明的患者数目仍在不断增加。因此,进一步探索和寻找新的针对DVC的防治策略是极其必要的。色素上皮衍生因子(pigmentepithelium—derivedfactor,PEDF)最初是在视网膜色素上皮细胞中发现的,一种属于丝氨酸蛋白酶抑制剂超基因家族但无抑制蛋白水解酶活性的糖蛋白,可以诱导视网膜母细胞瘤细胞Y2—79向成熟的神经元分化。胎儿和年轻人的视网膜色素上皮有较高水平PEDF基因表达,而衰老的细胞PEDF表达下调。随着对PEDF的深入认识,发现PEDF在糖尿病视网膜病、糖尿病肾病、糖尿病心血管疾病均起着有益的作用,可能成为防治DVC的新策略。本文就PEDF在DVC中的潜在治疗作用及研究进展做一综述。
