Abstract

OBJECTIVE

To investigate serum APPL1 level in patients with newly diagnosed type 2 diabetes mellitus (T2DM) and analyze its correlation with body mass index (BMI), waist-to-hip ratio (WHR), blood pressure, fasting plasma glucose, fasting blood insulin, HbA1c, and insulin resistance (HOMA-IR).

METHOD

Serum APPL1 levels were determined using ELISA in 22 normal control subjects and 63 patients with newly diagnosed T2DM, and HOMA-IR of the subjects was calculated using the HOMA model.

RESULTS

The diabetic patients had significantly elevated levels of serum APPL1 compared with the control subjects (85.71∓27.39 vs 64.52∓16.28 pg/ml, P<0.01), with also significantly increased BMI, WHR, SBP, FINS, LgHOMA-IR (P<0.01) and LDL-C (P<0.05) but lowered HDL-C (P<0.01). Fasting serum APPL1 levels were positively correlated with FPG, FINS, and HOMA-IR (r=0.215, 0.297, 0.334, P=0.014, 0.006, 0.002, respectively). In multiple linear regression analysis with APPL1 as the dependent variable, HOMA-IR (β=0.329, P=0.002) was included in the equation.

CONCLUSION

Patients with newly diagnosed T2DM have elevated serum APPL1 levels, suggesting the involvement of APPL1 in the development of T2DM.

摘要

目的

探讨新诊断2型糖尿病（T2DM）患者血清APPL1水平，并分析其与体重指数（BMI）、腰臀比（WHR）、血压、空腹血糖、空腹血胰岛素、糖化血红蛋白（HbA1c）及胰岛素抵抗（HOMA-IR）的相关性。

方法

采用酶联免疫吸附测定法（ELISA）检测22例正常对照者及63例新诊断T2DM患者的血清APPL1水平，并使用HOMA模型计算受试者的HOMA-IR。

结果

与对照组相比，糖尿病患者血清APPL1水平显著升高（85.71±27.39对64.52±16.28 pg/ml，P<0.01），BMI、WHR、收缩压（SBP）、空腹血胰岛素（FINS）、LogHOMA-IR（P<0.01）及低密度脂蛋白胆固醇（LDL-C，P<0.05）也显著升高，而高密度脂蛋白胆固醇（HDL-C，P<0.01）降低。空腹血清APPL1水平与空腹血糖（FPG）、FINS及HOMA-IR呈正相关（r分别为0.215、0.297、0.334，P分别为0.014、0.006、0.002）。以APPL1为因变量的多元线性回归分析中，HOMA-IR（β=0.329，P=0.002）纳入方程。
