Abstract:
Objective To investigate the serum levels of miR-488 and miR-654 in patients with diabetes nephropathy(DN)and their relationship with the severity and prognosis of the disease.Methods 92 DN patients who received treatment at Ya'an People's Hospital from January 2022 to January 2024(DN group)and 60 healthy controls(healthy group)were selected.The correlation between serum miR-488 and miR-654 was analyzed with pearson.The chi-square test was used to analyze the relationship between serum miR-488 and miR-654 expression levels,clinical pathological features,and degree of renal injury.ROC was used to predict the prognosis of DN patients Results Compared with healthy individuals,the expression level of serum miR-488(1.71±0.40 vs 1.08±0.15)was increased in DN patients,while the expression level of miR-654(0.66±0.19 vs 0.94±0.22)was reduced,and the differences were statistically significant(t=11.666,8.340,all P<0.05).In DN patients with diabetes≥10 years,24h urinary protein≥3 g/L,serum creatinine(Scr)≥150 μmol/L,glomerular filtration rate<60 ml/min/1.73m2,and blood urea nitrogen(BUN)≥7.5 mmol/L,the proportions of high expression of serum miR-488 and low expression of miR-654 were higher than the proportions of low expression of serum miR-488 and high expression of miR-654,and the differences were statistically significant(χ2=5.283～25.234;4.356～8.587,all P<0.05).Pearson analyze the correlation between serum miR-488 and miR-654 in the DN group were negatively correlated(r=-0.405),serum miR-488 was positively correlated with 24h urinary protein,Scr and BUN(r=0.376,0.435,0.406)and negatively correlated with glomerular filtration rate(r=-0.382).Serum miR-654 was negatively correlated with 24-hour urine protein,Scr and BUN(r=-0.418,-0.367,-0.425)and positively correlated with glomerular filtration rate(r=0.374).The proportions of high expression of miR-488 and low expression of miR-654 in DN patients with glomerular grade IV,2 points of interstitial inflammation,and 3 points of interstitial fibrosis and tubular atrophy(IFTA)were higher than proportions of low expression of miR-488 and high expression of miR-654,and the differences was statistically significant(χ2=7.916～20.669,8.432～13.258,all P<0.05).Compared with the poor prognosis group,the serum miR-488 expression level in the good prognosis group was obviously reduced(1.57±0.29 vs 1.89±0.17),while the miR-654 expression level was obviously increased(0.78±0.21 vs 0.51±0.19),and the differences were statisticolly significant(t=6.202,6.369,all P<0.05).The sensitivity of serum miR-488,miR-654 and their combination for prog-nosis of DN patients were 87.50%,80.00%and 90.00%,respectively.The specificity were 84.62%,86.54%and 82.69%,respec-tively.The AUC(95%CI)were 0.838(0.748～0.927),0.824(0.731～0.916)and 0.906(0.846～0.966),respectively,the joint prediction of the two was better than their individual predictions(Z=2.225,2.033,P=0.026,0.042).Conclusion The lower the degree of renal injury in DN patients,the lower the serum miR-488,and the higher the serum miR-654,serum miR-488 and miR-654 can be used to predict the condition and prognosis of DN patients,and combined prediction is better than individual predic-tion.
