-
摘要:
目的 探血清视黄醇结合蛋白(serum retinol binding protein,RBP)、超氧化物歧化酶(superoxide dismutase,SOD)、微小核糖核酸-206(microRNA-206,miR-206)与糖尿病肾病(diabetic nephropathy,DN)患者微炎性状态、肾功能恶化进展的相关性。 方法 选取河北省第三荣军优抚医院2022年1月至2024年4月收治的248例DN患者为肾病组,同时选取248例单纯2型糖尿病(type 2 diabetes mellitus,T2DM)患者为非肾病组。 结果 肾病组RBP、hs-CRP、TNF-α、IL-6高于非肾病组(P < 0.05),SOD、miR-206水平低于非肾病组(P < 0.05)。糖尿病病程长、高收缩压、高HbA1c、高hs-CRP、高TNF-α、高IL-6、高RBP、低miR-206、低SOD是DN发生的危险因素(P < 0.05)。进展组患者RBP水平高于非进展组(P < 0.05),miR-206、SOD水平低于非进展组(P < 0.05)。RBP、SOD、miR-206联合对肾功能恶化进展预测效能较好。 结论 RBP升高及miR-206、SOD降低与糖尿病肾病患者微炎性状态、肾功能恶化进展显著相关,且三项指标联测有助于评估患者肾功能恶化进展状况。 Abstract:Objective To explore the correlations of serum retinol binding protein (RBP), superoxide dismutase (SOD) and microRNA-206 (miR-206) with the microinflammatory state and the progression of renal function deterioration in patients with diabetic nephropathy (DN). Methods A total of 248 patients with DN admitted to the Third Rongjun Hospital of Hebei Province from January 2022 to April 2024 were selected as the nephropathy group, and 248 patients with type 2 diabetes mellitus (T2DM) alone were selected as the non-nephropathy group. Results The levels of RBP, hs-CRP, TNF-α and IL-6 in the nephropathy group were higher than those in the non-nephropathy group (P < 0.05), while the levels of SOD and miR-206 were lower than those in the non-nephropathy group(P < 0.05). Longer duration of diabetes, elevated systolic blood pressure, high HbA1c, high hs-CRP, high TNF-α, high IL-6, high RBP, low miR-206 and low SOD were risk factors for the occurrence of DN (P < 0.05). The RBP level in the progression group was higher than that in the non-progression group (P < 0.05), while the levels of miR-206 and SOD were lower than those in the non-progression group (P < 0.05). The combined detection of RBP, SOD, and miR-206 showed good predictive efficacy for the progression of renal function deterioration. Conclusion Elevated RBP and decreased miR-206 and SOD are significantly associated with the microinflammatory state and the progression of renal function deterioration in patients with DN, and the combined detection of these three indicators is helpful for evaluating the progression of renal function deterioration in these patients. -
