- Abstract: Objective To investigate the expression levels of microRNA-384(miR-384)and LIN28B in serum of patients with diabetic retinopathy(DR)and their diagnostic value.Methods A total of 100 patients with type 2 diabetes diagnosed in our hospital from January 2020 to November 2021 were selected as the research subjects.According to the occurrence of retinopathy,the patients were divided into the non-DR group(40 cases)and the DR group(60 cases).In addition,40 healthy person who underwent physical examination in our hospital during the same period were regarded as the control group.The relative expression levels of serum miR-384 and LIN28B were detected by qRT-PCR,and the relationship between the two indexes and the general clinical data of DR patients was analyzed.Pearson method was applied to analyze the correlation between the expression of miR-384 and LIN28B in serum of DR patients.Logistic regression was applied to analyze the influencing factors of DR.The diagnostic value of serum miR-384 and LIN28B levels for DR patients was analyzed by receiver operating characteristic(ROC)curve.Results The level of serum miR-384 in the DR group was obviously lower than that in the non-DR group and the control group(P<0.05),and the non-DR group was lower than the control group(P<0.05).The level of serum LIN28B in the DR group was obviously higher than that in the non-DR group and the control group(P<0.05),and the non-DR group was higher than the control group(P<0.05).The expression levels of miR-384 and LIN28B were related to the course of diabetes and blood glucose(P<0.05).Pearson's correlation analysis showed that the expression of miR-384 was negatively correlated with LIN28B in serum of DR patients(r=-0.296,P<0.05).Logistic regression analysis showed that miR-384 and LIN28B were the independent influencing factors for DR(P<0.05).The results of ROC curve analysis showed that the area under the curve(AUC)of miR-384,LIN28B and the combination of two in DR patients was 0.625,0.646,and 0.682,respectively,and the specificity was 67.50%,85.00%,and 97.50%,respectively.Conclusion The serum expression of miR-384 is low and LIN28B is high in DR patients.Both miR-384 and LIN28B are the influencing factors for the occurrence of DR and are expected to be potential serological markers for the diagnosis of DR.
