目的 探討碘131（131I）治療后Graves眼病（GO）預后與血清促甲狀腺激素受體抗體（TRAb）水平變化之間的關系。 方法 選擇2011年5月－12月初發(fā)Graves病患者238例，分為GO組124 例和非GO組114 例，分別檢測131I治療前及131I治療后2、3、6個月甲狀腺功能和TRAb，GO患者131I治療前和治療后6 個月進行臨床活動度評分（CAS）。 結果 131I治療前各組TRAb水平差異無統(tǒng)計學意義（P＞0.05），TRAb水平與GO CAS評分之間無相關；131I治療后6個月所有患者TRAb水平顯著增加；非GO組有5例新發(fā)GO，新發(fā)GO組與其他患者的TRAb水平分別為（58.7 ± 77.9）、（61.9 ± 81.1）U/L，差異無統(tǒng)計學意義（P＞0.05）；GO組又分為GO無變化29例，GO加重17例，GO緩解78例，三組患者TRAb水平分別為（53.5 ± 77.6）、（66.2 ± 89.9）、（66.8 ± 42.2）U/L，差異無統(tǒng)計學意義（P＞0.05）。 結論 131I治療后患者TRAb水平顯著增加，但TRAb水平的變化和GO預后無關，TRAb與GO的關系還需要進一步研究。

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.
