Objective. To assess the prognostic value of serum interleukin-6 (IL-6), nuclear factor-κB (NF-κB), and monocyte chemoattractant protein 1(MCP-1) assay in patients with diabetic nephropathy. Methods. From May 2019 to March 2020, 104 patients with diabetic nephropathy treated in our institution assessed for eligibility were recruited and assigned at a ratio of 1 : 1 to either the observation group ([urinary albumin excretion rate (UAER)] of 30 mg-300 mg/24 h) or the research group ([UAER] >300 mg/24 h). IL-6, MCP-1, renal function indices, and NF-κB levels were determined, and their correlation with DN was analyzed. Logistic regression was used to analyze the influencing factors of end-stage renal disease in patients with diabetic nephropathy. The receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC) was calculated to analyze the predictive value of combined detection of IL-6, MCP-1, and NF-κB in the prognosis of patients with diabetic nephropathy. Results. The eligible patients with UAER of 30 mg-300 mg/24 h were associated with significantly higher levels of IL-6, MCP-1, NF-κB, blood urea nitrogen (BUN), and serum creatinine (Scr) versus those with UAER >300 mg/24 h ( P < 0.05 ). During the follow-up, a total of 38 patients progressed to end-stage renal diseases. Eligible patients with end-stage renal diseases showed significantly higher serum IL-6, MCP-1, and NF-κB levels versus those without end-stage renal diseases ( P < 0.05 ). Serum IL-6, MCP-1, and NF-κB are independent risk factors for the occurrence of end-stage renal disease in patients with diabetic nephropathy. The AUCs of IL-6, MCP-1, and NF-κB for predicting the prognosis of patients with diabetic nephropathy were 0.562, 0.634, and 0.647, respectively, and the AUC of the three combined detection for predicting the prognosis of patients with diabetic nephropathy was 0.889. Conclusion. Serum IL-6, NF-κB, and MCP-1 levels are closely related to renal injury and poor prognosis in patients with diabetic nephropathy, and the combined assay is valuable for assessing patients’ condition and prognosis.

Background: As the most convenient and commonly used for clinical diagnosis, cancer biomarker has been widely used in the auxiliary diagnosis of tumors, the observation of curative effect, the judgment of prognosis, and the monitoring of the disease. Methods: Pan-cancer analysis was used to validate the value of Dehydrogenase/Reductase 2 (DHRS2) as a tumor prognostic marker in various tumors. The relationship of DHRS2 to TMB and MSI was used to explain the effect of DHRS2 on genomic instability. Online cbioportal was used to analyze DHRS2 mutations in tumors. Finally, 33 clinical tumor samples were collected in 2021 who were enrolled into the Affiliated Lianyungang Oriental Hospital of Xuzhou Medical University, to verify the expression and diagnostic prognostic value of DHRS2. Results: The expression of DHRS2 was up-regulated in a variety of tumors and had adverse effects on the overall survival, disease-free interval, and progression-free interval of tumor patients. DHRS2 was associated with tumor genome instability, confirming that DHRS2 was correlated with tumorigenesis. In addition, DHRS2 had different mutation sites in various tumors. DHRS2 was up-regulated and was a poor prognosis biomarker in clinical tumor samples. Conclusion: DHRS2 was aberrantly expressed in tumors and has diagnostic prognostic value.
