				        	Objective To investigate the diagnostic value of serum MK (Midkine)and total bilirubin (TB)in diabetic retinopathy (DR). Methods A total of 148 patients with type 2 diabetes were divided into three groups:diabetes without retinopathy (NDR group,n = 50),diabetic with non proliferative retinopathy (NPDR group,n = 52 )and diabetic with proliferative retinopathy (PDR group,n = 46 ) according to whether retinal lesions were detected. The diagnostic value of serum MK and TB were investigated. Results Age,gender,body mass index (BMI),FPG,HbA1 c,TG,TC,LDL-C,HDL-C, SBP,DBP were not statistically different among the three groups (P >0.05).Duration,UAlb/Cr,SOD, MDA,AOPP,MK,TB and DB were statistically different among the three groups (P<0.05). Duration, ALB/CR,MDA,AOPP,and MK were higher,SOD,TB,DB were lower in PDR and NPDR group than in NDR group (P<0.05). Duration,UAlb/Cr,MDA,AOPP,and MK were higher,and SOD,TB,DB were lower in PDR group than in NPDR group (P <0.05).Logistic regression analysis showed that duration, ALB/CR,MDA,AOPP,and MK were risk factors (OR =1.36,1.71,1.27,1.65,2.35,P <0.05 )and SOD,TB,DB were protective factors for DR (OR =0.46,0.31,0.46,P <0.05). Diagnosis sensitivity, specificity,positive predictive value,negative predictive value and accuracy of TB combined with MK were higher than TB,MK alone(AUC=0.918,0.735,0.762,P <0.05). Conclusion DR may be associated with increased MK and decreased TB.Diagnostic efficacy of MK combined with TB is better than MK,TB alone.
