Abstract:
AIM: To discuss the expression and diagnostic value of serum trefoil factor 1(TFF1)and annexin A2(ANXA2)in diabetic retinopathy(DR).METHODS:A total of 50 DR patients(100 eyes; research group)and 50 type 2 diabetes mellitus(T2DM)patients(100 eyes; control group)without retinopathy who visited our hospital between January 2022 and December 2024 were recruited. Enzyme linked immunosorbent assay was performed to test serum TFF1 and ANXA2. Pearson method was performed to analyze the correlation between serum TFF1 and ANXA2 in DR. Logistics method was used to discuss the influencing factors of retinopathy in T2DM patients. ROC was performed to analyze the diagnostic value of serum TFF1 and ANXA2 in DR.RESULTS: The research group had clearly longer T2DM course, higher glycated hemoglobin, total cholesterol(TC), and serum ANXA2 than the control group(all P<0.001); the research group had significantly lower serum TFF1 than the control group(P<0.001); Serum TFF1 and ANXA2 in DR patients were negatively correlated(r=-0.345, P=0.014). The expression of serum TFF1 and ANXA2 was influencing factor for the occurrence of retinopathy in T2DM patients(all P<0.05). The AUC of serum TFF1 in diagnosing DR was 0.831(95%CI=0.746-0.916), and the AUC of serum ANXA2 in diagnosing DR was 0.832(95%CI=0.755-0.908). The combination of the two had an AUC of 0.932(95%CI=0.884-0.980)for diagnosing DR. The combination of serum TFF1 and ANXA2 had a higher diagnostic value for DR than individual diagnosis(Zcombination-TFF1=2.883, P=0.004; Zcombination-ANXA2=2.947, P=0.003).CONCLUSION: Serum TFF1 is reduced and serum ANXA2 is increased in DR patients. These changes are associated with the increase in risk of retinopathy in T2DM. The combination of serum TFF1 and ANXA2 has certain diagnostic value for DR.
