               【摘要】 背景 估算肾小球滤过率(eGFR)是反映慢性肾脏病严重程度的量化指标之一。研究表明糖尿病前
           期血糖升高可增加慢性肾脏病风险,但对 eGFR 直接影响报道较少。目的 探讨社区人群中空腹血糖(FPG)受损患
           者血糖水平对 eGFR 的影响。方法 选择 2020 年 1—12 月于南昌大学第二附属医院体检中心体检的人群,收集一般
           资料与临床资料(包括既往史、性别、年龄、体质指数、血压、尿酸、血脂、FPG、尿常规、血肌酐),经相应纳入
           标准与排除标准筛选,最终纳入 28 601 例受试者。根据 FPG 水平将受试者分为 FPG 升高组(5.6 mmol/L ≤ FPG<7.0
           mmol/L)、FPG 正常组(3.9 mmol/L ≤ FPG<5.6 mmol/L),比较两组一般资料与临床资料。为明确 FPG 对 eGFR 影
           响,采用个案匹配控制对两组受试者进行多因素(性别、年龄、平均动脉压、尿酸、总胆固醇、体质指数)匹配,
           采用 Mann-Whitney U 秩和检验比较匹配后两组一般资料。采用 Spearman 秩相关检验分析 FPG 与 eGFR 在 FPG 升高
           组、FPG 正常组及匹配后 FPG 升高组、FPG 正常组间的相关性。结果 共获得 FPG 正常组患者 25 539 例、FPG 升高
           组患者 3 062 例。两组年龄、平均动脉压、尿酸、胆固醇、体质指数、eGFR 比较,差异有统计学意义(P<0.05);经
           多因素匹配后,两组年龄、平均动脉压、尿酸、胆固醇、体质指数比较,差异无统计学意义(P>0.05),FPG 升高组
           eGFR 较 FPG 正常组更高(P<0.05)。相关性分析显示,全人群中 FPG 对 eGFR 呈负相关(r s =-0.047,P<0.05),匹
           配人群中 FPG 对 eGFR 影响呈正相关(r s =0.065,P<0.05),且匹配人群 FPG 升高亚组中相关系数进一步增加(r s =0.127,
           P<0.05)。结论 FPG 受损会引起 eGFR 升高,这为糖尿病前期血糖升高出现的肾小球高滤过状态提供可能的临床推断。

               【Abstract】 Background Estimated glomerular filtration rate(eGFR)is a quantitative indicator assessing the
           severity of chronic kidney disease. Studies have shown that elevated glucose in prediabetic period increases the risk of chronic
           kidney disease,but its direct effect on eGFR has been less reported. Objective To investigate the effect of fasting blood glucose
           level on eGFR in a community-dwelling population with impaired fasting glucose(IFG). Methods Participants(n=28 601)
           were selected from a group of physical examinees from Physical Examination Center,the Second Affiliated Hospital of Nanchang
           University during January to December 2020 according to the inclusion criteria and exclusion criteria. Demographic and clinical
           data〔past medical history,sex,age,BMI,blood pressure,serum uric acid,lipids,and creatinine,fasting plasma glucose(FPG),
           routine urine parameters〕were collected and compared between subjects with elevated FPG(5.6 mmol/L ≤ FPG<7.0 mmol/L)
           and those with normal FPG(3.9 mmol/L ≤ FPG<5.6 mmol/L). The influence of FPG on eGFR was assessed by the Mann-
           Whitney U-test comparing multiple factors〔sex,age,mean arterial pressure(MAP),serum uric acid,total cholesterol,
           BMI〕 between subjects with elevated and normal FPG after matching. The correlation between FPG and eGFR was assessed in
           subjects with elevated and normal FPG before and after matching. Results There were 25 539 individuals with normal FPG,and
           3 062 with elevated FPG. There were significant difference in age,MAP,serum uric acid,total cholesterol,BMI and eGFR
           between the two groups(P<0.05). Individuals with elevated FPG had higher eGFR than those with normal eGFR(P<0.05)
