Abstract:
Objective:To investigate the expression level of miR-24-3p in peripheral blood of patients with type 2 diabetic nephropathy (DN) and its clinical significance.Methods:A cross-sectional study was conducted among 100 patients with simple type 2 diabetes mellitus (T2DM group) and 103 patients with DN (DN group). The relative expression level of miR-24-3p in the peripheral blood of patients in both groups was measured. Differences in miR-24-3p expression level among patients with DN were analyzed. The efficacy of miR-24-3p expression level in predicting the occurrence of DN was assessed.Results:The relative expression level of miR-24-3p in the peripheral blood of patients with DN was significantly higher than that of patients with T2DM [(1.43 ± 0.43) vs. (1.07 ± 0.33), t = -6.82, P < 0.05]. Significant differences in miR-24-3p level were observed among DN patients with varying levels of fasting blood glucose, glycated hemoglobin A1c, estimated glomerular filtration rate, and serum creatinine and magnesium levels ( t = -2.92, -2.90, -3.84, -3.41, -4.17, all P < 0.05). There was a statistically significant difference in miR-24-3p level among DN patients with different degrees of renal interstitial inflammation and renal interstitial fibrosis and tubular atrophy scores ( F = 48.73, 27.07, both P < 0.05). Correlation analysis revealed that the relative expression level of miR-24-3p in the peripheral blood of patients with DN was positively correlated with fasting blood glucose, glycated hemoglobin A1c, serum creatinine, renal interstitial inflammation score, and renal interstitial fibrosis and tubular atrophy score ( r = 0.48, 0.57, 0.63, 0.71, 0.69, all P < 0.05). It was negatively correlated with estimated glomerular filtration rate and blood magnesium level ( r = -0.72, -0.78, both P < 0.05). The relative expression level of miR-24-3p in the peripheral blood can be used to predict the occurrence of DN [area under the curve = 0.864, 95% CI: (0.813, 0.916)], and the sensitivity and specificity of this prediction were 85.0% and 79.6%, respectively. Conclusions:The expression of miR-24-3p is high in the peripheral blood of patients with DN, and its level is associated with blood glucose metabolism, blood magnesium level, renal inflammatory injury, renal interstitial fibrosis, and glomerular atrophy. Upregulation of miR-24-3p may increase the risk of renal disease and exacerbate kidney damage in patients with T2DM.
