               [摘   要] 目的:观察达格列净对早期糖尿病肾病(diabetic kidney disease,DKD)患者的疗效及对调节性 T 细胞(regulatory T
                cell,Treg)和炎症因子的影响。方法:入选 2019 年 8—12 月南京医科大学附属江宁医院门诊收治的 DKD 患者 47 例为研究对
                象。所有患者在原先降糖治疗的基础上均给予达格列净10 mg/d,口服4周,保持饮食以及运动方式不变。比较治疗前后静脉
                空腹血糖(fasting blood glucose,FBG)、糖化白蛋白(glycated albumin,GA)、尿白蛋白⁃肌酐比值(urinary albumin/creatinine ratio,
                UACR)、24 h尿蛋白定量、估算的肾小球滤过率(estimated glomerular filtration rate,eGFR)、外周血Treg、外周血白介素(interleukin,
                IL)⁃6、IL⁃1β、肿瘤坏死因子(tumor necrosis factor,TNF)⁃β和 IL⁃10 的水平,并记录药物不良反应。结果:达格列净治疗 4 周
                后 FBG[(8.96±0.83)mmol/L vs.(7.42 ± 0.67)mmol/L]、GA[(18.47 ± 3.32)% vs.(15.49 ± 2.62)%]、24 h 尿 蛋 白 定 量
               [1.14(0.29,2.08)g/24 h vs. 0.28(0.15,0.83)g/24 h]以及 UACR[80(45,150)mg/g vs. 40(30,80)mg/g]较治疗前均明显下降
               (P < 0.05),eGFR 较治疗前也有所下降[(105.30 ± 36.01)mL/(min·1.73 m)vs.(92.07 ± 35.26)mL/(min·1.73 m),P < 0.05],
                                                                                                      2
                                                                         2
                但在治疗 8 周后可恢复至治疗前水平[(104.88 ± 36.86)mL/(min·1.73 m)vs.(105.30 ± 36.01)mL/(min·1.73 m),P > 0.05]。治疗
                                                                     2
                                                                                                  2
                4周后Treg 的表达量较治疗前明显上调[(3.19 ± 0.74)% vs.(5.64 ± 0.93)%,P < 0.05],促炎因子 IL⁃1β[(7.83 ± 1.39)ng/L vs.
               (4.57 ± 0.71)ng/L]、TNF⁃β[(372.85 ± 6.79)ng/L vs.(227.62 ± 7.29)ng/L]、IL⁃6[(3.99 ± 0.47)ng/L vs.(2.59 ± 1.01)ng/L]的
                表达量较治疗前明显下调(P < 0.05),抑炎因子 IL⁃10 的表达量较治疗前上调[(0.03 ± 0.01)ng/mL vs.(0.05 ± 0.01)ng/mL,
                P < 0.05]。治疗期间,无患者出现低血糖、酮症等不良反应,有5例患者出现无症状性尿路感染。结论:达格列净可能通过上
                调Treg的表达来抑制炎症反应,对DKD具有肾脏保护作用。

               [Abstract] Objective:This study aims to observe the efficacy of dapagliflozin on patients with early diabetic kidney disease(DKD)

                and the influence on expression of regulatory T cells(Tregs)and inflammatory factors. Methods:Forty⁃seven patients who developed
                DKD between August 2019 and December 2019 in the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled. On
                the basis of the original hypoglycemic therapy,all patients were prescribed dapagliflozin 10 mg,qd,orally,for 4 weeks and kept diet
                and exercise mode unchanged. Fasting plasma glucose(FBG),glycated albumin(GA),urinary albumin creatinine ratio(UACR),24⁃hour
                urinary protein and estimated glomerular filtration rate(eGFR)were compared between baseline and 4⁃week after prescription. The
                level of Tregs in peripheral blood detected by flow cytometry,the levels of interleukin(IL)⁃6,IL⁃1β,tumor necrosis factor(TNF)⁃β and
                IL⁃10 measured by ELISA were also compared. Adverse drug reactions were recorded. Results:After 4 weeks of dapagliflozin treatment,
