Abstract: Objective To analyze the changes of leptin and adiponectin levels in serum of patients with diabetic retinopathy and investigate their chnical significance in diabetic retinopathy (DR).Methods One hundred and twenty-one patients with type 2 diabetes mellitus as the case group who hospitalized from Nov.2012 to Nov.2013.Among the patients,41 cases of non-DR,40 cases of nonproliferative-DR,40 cases of proliferativeDR.Forty healthy were served as the control group.The levels of leptin and adiponectin in serum were detected by Enzyme-Linked Immuno Sorbent Assay (ELISA).Results The overall levels of leptin in case group was (15.25 ± 4.70) μg/L,significantly higher than the control group ((6.15 ± 1.70) μg/L; t =-11.696,P ＜0.01)).The level of adiponectin in case group was (7.39 ± 1.92) mg/L,lower than the control group ((11.10 ± 1.46) mg/L; t =11.216,P ＜ 0.01).Moreover,the levels of leptin increased successively from (10.91 ±1.21) μg/L in NDR,(15.22 ±3.75) μg/ L in NPDR and (20.50 ±3.70) μg/L in PDR.While,the adiponectin levels decreased from (9.61 ± 1.35) mg/L in NDR,(7.11 ± 1.18) mg/L in NPDR and (5.34 ± 1.36) mg/L in PDR respectively.And the differences between the groups were significant(F =149,542,291,550;P ＜0.05).The levels of leptin and adiponectin in serum showed a negative correlation (r =-0.662,P ＜0.01).Condusion Levels of leptin and adiponectin in serum associate with DR,and both of them might be the important indexes for the prediction and curative effect evaluation of DR.
