Abstract
Angiopoietin-2 levels were 5. 80 ( 3. 83-8. 00 ) , 4. 42 ( 2. 56-5. 55 ) , and 2. 75 ( l. 40-4. 64 )ng/ml in type 2 diabetic patients with proliferative retinopathy, patients with non-proliferative retinopathy, and patients without retinopathy, respectively. Statistical significances existed between any two groups (all P ＜0. 01 ). Angiopoietin-1 level in patients with non-proliferative retinopathy was higher than that in patients without retinopathy [10. 57 ( 8. 99-12. 05 ) vs 9. 21 (7. 71-11.2 ) ng/ml, P＜0. 05]. No difference in receptor Tie-2 was found among the 3 groups (P＞0. 05 ). The results suggested that serum angiopoietin-2 level might be associated with the severity of retinopathy in type 2 diabetic patients. Key words: Angiopoietin; Receptor Tie-2; Diabetes mellitus, type 2; Retinopathy
