  • Change of Serum TRAb Level in Patients with Graves’ Ophthalmopathy before and after Treated with 131I

    目的 探讨碘131(131I)治疗后Graves眼病(GO)预后与血清促甲状腺激素受体抗体(TRAb)水平变化之间的关系。 方法 选择2011年5月-12月初发Graves病患者238例,分为GO组124 例和非GO组114 例,分别检测131I治疗前及131I治疗后2、3、6个月甲状腺功能和TRAb,GO患者131I治疗前和治疗后6 个月进行临床活动度评分(CAS)。 结果 131I治疗前各组TRAb水平差异无统计学意义(P>0.05),TRAb水平与GO CAS评分之间无相关;131I治疗后6个月所有患者TRAb水平显著增加;非GO组有5例新发GO,新发GO组与其他患者的TRAb水平分别为(58.7 ± 77.9)、(61.9 ± 81.1)U/L,差异无统计学意义(P>0.05);GO组又分为GO无变化29例,GO加重17例,GO缓解78例,三组患者TRAb水平分别为(53.5 ± 77.6)、(66.2 ± 89.9)、(66.8 ± 42.2)U/L,差异无统计学意义(P>0.05)。 结论 131I治疗后患者TRAb水平显著增加,但TRAb水平的变化和GO预后无关,TRAb与GO的关系还需要进一步研究。

  • Combined Measurement of Serum Cystatin C, 99mTc-DTPA and Urine Microalbumin in Early Diagnosis of Type 2 Diabetic Nephropathy

    【摘要】 目的 以99mTc-DTPA肾动态显像法肾小球滤过率(glomerular filtration rate,GFR)测定为标准,将血清胱抑素C(cystatin C, CysC)检测与其比较,探讨CysC测定在2型糖尿病肾病(type 2 diabetic nephropathy,T2DN)诊断中的意义。 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)分为两组:正常蛋白尿组(31例)和微量蛋白尿组(45例),同时测定GFR、CysC、血清肌酐(serum creatinine, Scr)和糖化血红蛋白(hemoglobin A1c, HbA1c),并设正常自愿者38名作为对照组,进行统计学分析。 结果 对照组、T2DM正常蛋白尿组及T2DM微量蛋白尿组CysC水平分别为(1.1±0.6)、(1.6±0.7)、(1.0±0.3) mg/L,各组差异均有统计学意义(Plt;0.05);HbA1c水平分别为(5.4±0.6)%、(7.1±2.7)%、(7.9±3.1)%、两组T2DM患者与对照组比较,差异均有统计学意义(Plt;0.05);GFR水平分别为(80.9±23.0)、(74.2±26.1)、(79.3±19.7) mL/(min•1.73 m2),各组差异无统计学意义(Pgt;0.05);Scr水平分别为(87.7±23.8)、(93.7±38.4)、(81.5±11.4) μmol/L,组间差异无统计学意义(Pgt;0.05)。CysC、Scr和GFR之间呈负相关(r=-0.694,-0.692;Plt;0.001);CysC和Scr之间呈正相关(r=0.903,Plt;0.001)。 结论 CysC可作为早期T2DN的检测指标,具有较高的敏感性,但对于轻度到中度GFR降低的诊断准确性并不优于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.
