【摘要】 目的 以99mTc-DTPA腎動態顯像法腎小球濾過率（glomerular filtration rate，GFR）測定為標準，將血清胱抑素C（cystatin C， CysC）檢測與其比較，探討CysC測定在2型糖尿病腎病（type 2 diabetic nephropathy，T2DN）診斷中的意義。 方法 2010年6月—2011年1月76例2型糖尿病（type 2 diabetes mellitus，T2DM）患者按24 h尿微量白蛋白（microalbuminuria，m-Alb）分為兩組:正常蛋白尿組（31例）和微量蛋白尿組（45例），同時測定GFR、CysC、血清肌酐（serum creatinine， Scr）和糖化血紅蛋白（hemoglobin A1c， HbA1c），并設正常自愿者38名作為對照組，進行統計學分析。 結果 對照組、T2DM正常蛋白尿組及T2DM微量蛋白尿組CysC水平分別為（1.1±0.6）、（1.6±0.7）、（1.0±0.3） mg/L，各組差異均有統計學意義（Plt;0.05）；HbA1c水平分別為（5.4±0.6）%、（7.1±2.7）%、（7.9±3.1）%、兩組T2DM患者與對照組比較，差異均有統計學意義（Plt;0.05）；GFR水平分別為（80.9±23.0）、（74.2±26.1）、（79.3±19.7） mL/（min?1.73 m2），各組差異無統計學意義（Pgt;0.05）；Scr水平分別為（87.7±23.8）、（93.7±38.4）、（81.5±11.4） μmol/L，組間差異無統計學意義（Pgt;0.05）。CysC、Scr和GFR之間呈負相關（r=-0.694，-0.692；Plt;0.001）；CysC和Scr之間呈正相關（r=0.903，Plt;0.001）。 結論 CysC可作為早期T2DN的檢測指標，具有較高的敏感性，但對于輕度到中度GFR降低的診斷準確性并不優于Scr。【Abstract】 Objective To demonstrate the clinical value of serum cystatin-C (CysC) in the assessment of renal function in type-2 diabetic nephropathy (T2DN) by comparing it with the glomerular filtration rate (GFR) measured by 99mTc-DTPA method. Methods From June 2010 to January 2011, 76 patients with type 2 diabetes mellitus (T2DM) were classified into two groups according to their 24 h microalbuminuria (m-Alb) level: the normal albuminuric group (n=31) and the microalbuminuric group (n=45). GFR, Serum creatinine (Scr), CysC, and hemoglobin A1c (HbA1c) were measured. Thirty-eight healthy subjects were recruited as the control group, and statistical analysis was carried out. Results The CysC levels in the control group, the normal albuminuric group and the microalbuminuria group were respectively (1.1±0.6), (1.6±0.7) and (1.0±0.3) mg/L, with a significant difference among the three groups (Plt;0.05). HbA1c level in the three groups were respectively (7.1±2.7)%, (7.9±3.1)% and (5.4±0.6)%, with a significant difference between the two diabetic groups and the control group (Plt;0.05). Scr levels in the three groups were respectively (87.7±23.8), (93.7±38.4), (81.5±11.4) μmol/L; GFR levels in the three groups were respectively (80.9±23.0), (74.2±26.1), (79.3±19.7) mL/(min?1.73 m2); among the three groups the differences of both Scr and GFR were not significant. Both CysC and Scr were negatively correlated with GFR (r=-0.694,-0.692;Plt;0.001), and CysC was positively correlated with Scr (r=0.903, Plt;0.001). Conclusion Increased CysC may be an early indicator of incipient diabetic nephropathy, but the diagnostic accuracy of CysC is not superior to that of Scr in distinguishing between mildly and moderately reduced GFR.
【摘要】 目的 評價尿蛋白與尿肌酐比值檢測在子癇患者中的診斷意義。 方法 回顧分析 35例子癇患者的臨床資料。患者年齡20~34歲,平均年齡(2681±639)歲;孕周22~34周,平均孕周(2902±419)周。平均血壓(15620±1235 )mm Hg(1 mm Hg=0133 kPa)。均檢測24 h尿蛋白及點時尿檢測尿蛋白與尿肌酐比值,采用線形回歸分析尿蛋白與尿肌酐比值與24 h尿蛋白結果相關性。結果 35例患者24 h尿蛋白水平(351±116) g/24 h,〖JP〗直線回歸分析顯示尿蛋白與尿肌酐比值與24 h尿蛋白水平呈正相關(R=0897,Plt;001)。結論 尿蛋白與尿肌酐比值可能是一個重要的用于子癇患者尿蛋白篩查的指標。【Abstract】 Objective To investigate the diagnostic significance of urinary spot protein:creatinine ratio in Eclampsia.Method Thirtfive pregnant patients suffering from eclampsia with average age of (2681±639) years old were enrolled in this study.All patients were examined both urinary protein over 24 hours and urinary spot protein:creatinine ratio. The correlation between urinary protein over 24 hours to urinary spot protein:creatinine ratio with linear regression were analyzed. Result The rinary protein of 35 patients over 24 hours were (351±116) g/24 h,meanwhile the urinary spot protein:creatinine ratio were (0345±017) g/mmol. With linear regression, urinary spot protein:creatinine ratio had a positive correlation with the data of urinary protein over 24 hours (R=0897,Plt;001). Conclusion The spot protein:creatinine ratio is a reasonable test for detecting proteinuria in eclampsia pregnancy.
摘要:目的:了解血肌酐清除率受損是否與冠心病患病率存在聯系。方法:納入2006年7月至2008年2月期間經冠狀動脈造影證實的冠心病患者及年齡、性別匹配的對照組,按血肌酐清除率值將患者分為正常［≥90 mg/（mL·173 m2)］,輕度受損［≥60 mg/（mL·1.73 m2）,lt;90 mg/（mL·1.73 m2)］和明顯受損［lt;60 mg/（mL·1.73 m2)］。比較冠心病組與對照組各組人群的比例有無差異。結果:研究期間共納入冠心病組和對照組患者各116例。在冠心病組中,血肌酐清除率正常患者82例、輕度受損29例、重度受損5例,對照組中,正常患者98例、輕度受損13例、重度受損5例,〖JP3〗兩組比較分布有統計學差異(χ2值7.517,P=0.023)。與對照組比較,冠心病組的血清肌酐值無明顯差異（Pgt;005)，〖JP〗冠心病組（103.29±51.08） μmol/L,對照組（102.67±41.21）μmol/L。結論:血肌酐清除率降低是冠心病的危險因素。Abstract: Objective: To disclose the relation of the estimated glomerular filtration rate (eGFR) and coronary artery disease. Methods：We analyzed eGFR in the patients with coronary artery disease confirmed by coronary angiography and the control, and compared the proportion of patients with reduced renal function in the different groups. Results: A total 116 cases were included in each group. Among these patients, normal renal function, mildly and severe reduced renal function was documented in 82, 29 and 5 in coronary artery disease group, and in 98, 13 and 5 in the control group, respectively. In comparison to the control, more patients with reduced eGFR were found in coronary artery disease group (χ2 value 7.517,P=0.023), although no significant difference was observed between both groups（Pgt;0.05). Conclusion: Reduced eGFR, even if mildly, could be regarded as the risk factor of coronary artery disease.
