Abstract： 目的 测定新诊断2型糖尿病患者血清磷酸酪氨酸衔接蛋白(APPL)1水平,分析血清APPL1水平与体质量指数(BMI)、体脂分布(WHR)、收缩压(SBP)、舒张压(DBP)、空腹血糖(FPG)、空腹血清胰岛素(FINS)、糖化血红蛋白(HbAlc)、胰岛素抵抗指数(HOMA-IR)等的关系,初步探讨新诊断2型糖尿病患者血APPL1水平的变化.方法 应用酶联免疫吸附法(ELISA)对临床上新诊断的2型糖尿病患者63例(病例组)和健康对照者22例(对照组),进行空腹血清APPL1水平测定.稳态模型(HOMA-MODEL)计算胰岛素抵抗指数(HOMA-IR).结果 (1)病例组血清APPL1水平(85.71±27.39) pg/ml显著高于对照组(64.52±16.28) pg/ml,差异有统计学意义(P＜0.01)；(2)2型糖尿病(T2DM)组BMI、WHR、SBP、FINS、LgHOMA-IR均高于对照组(P＜0.01),低密度脂蛋白胆固醇(LDL-C)高于对照组(P＜0.05)；而T2DM组高密度脂蛋白胆固醇(HDL-C)显著低于对照组(P＜0.01)；(3)APPL1与空腹血糖(FPG)、空腹血胰岛素(FINS)、胰岛素抵抗指数(LgHOMA-IR)呈显著正相关关系(r=0.215、0.297、0.334,P=0.014、0.006、0.002)；(4)以APPL1为应变量进行多元线性回归分析,结果胰岛素抵抗指数(B=0.329,P=0.002)进入方程.结论 新诊断2型糖尿病患者血清APPL1水平增高,APPL1可能与2型糖尿病的发生发展密切相关.
