[摘要] 目的 通過測定血中3-磷酸甘油醛脫氫酶的活性,探討GAPD在糖尿病腎病早期診斷中的意義。 方法 測定190例健康者和80例2型糖尿病患者的血GAPD,尿微量白蛋白和β2-微球蛋白,對結果進行統計分析。 結果 疾病組中GAPD活性水平均高于正常對照組,差異有統計學意義(P<0.05)。疾病組中的微量白蛋白尿組、大量白蛋白尿組中的微量白蛋白和β2-微球蛋白高于正常對照組,差異有統計學意義(P<0.05)。但是正常白蛋白尿組中的微量白蛋白和β2-微球蛋白與對照組相比差異無統計學意(P>0.05)。 結論 GAPD在正常白蛋白尿期活性已經發生變化,比微量白蛋白和β2-微球蛋白活性變化更早,能夠提早預測糖尿病腎臟疾病的發生,有利于臨床做出診斷,改善患者的預后。

[Abstract] Objective To explore the significance of GAPD in diabetic nephropathy through determining the activity of blood GAPD. Methods To analyze the determined results of 190 healthy and 80 patients of type 2 diabetes patients, the activity of GAPD, microalbuminuria and β2-micro- globulin. Results Activity of GAPD in three disease group were higher than the normal group (P<0.05). mALB and β2-M in two disease group of the abnormal microalbuminuria group were higher than the control group (P<0.05), but compared with the control group mALB and β2-M in normal albuminuria group had no significant difference (P>0.05).GAPD in disease group had no difference (P>0.05). mALB and β2-M meaningful were differences between the three groups (P<0.05) . Conclusion Activity of GAPD has been changed in normal proteinuria and earlier than mALB and β2-M.It can be forecast early diabetic kidney disease, easy to make a diagnosis for clinic and improve the prognosis of patients.

糖尿病(diabetes mellitus,DM)可以使體內的多個臟器受累,糖尿病腎病(diabetic nephropathy,DN)就是糖尿病的最主要的慢性并發癥之一,也是糖尿病主要死因之一[1]。糖尿病腎病起病隱匿,在早期很少有臨床癥狀,一旦出現臨床癥狀,尿中將存在明顯而且持續的蛋白,就會慢慢演變為腎衰竭[2]。因此在糖尿病早期對其診斷并及時干預治療,可以減緩腎功能減退,改善預后,提高人們的生活質量。現階段對糖尿病腎病診斷的最可靠的方法依舊是腎臟活檢,但是腎臟活檢不但對操作者的技術要求高,而且對患者的創傷大,費用也高,臨床推廣比較困難[3]。常規的實驗室檢查像尿蛋白定量、肌酐、尿素氮等又很難發現腎臟的早期病變,因此當務之急是尋找一種創傷小、費用低、操作簡便的檢測方法,來檢測腎臟的早期損害。……
