Objective: To investigate the relationship between erythrocyte magnesium, protein tyrosine phosphatase (PTP) and blood glucose in diabetic patients. Methods: Fasting blood glucose (FPS) insulin concentration (FINS) was measured in 30 diabetic patients (DM) and 20 normal controls (NT) by glucose oxidase and radioimmunoassay. Plasma magnesium oxide The results showed that the age, weight and body mass index (BMI) of DM group were not significantly different from those of NT group (57.33 ± 7.21 vs 58.35 ± (61.00 ± 8.29) vs (61.95 ± 6.96); BMI (kg · m -2) :( 23.50 ± 2.50 ) Vs (2340 ± 2.70); systolic blood pressure (kPa) :( 16,41 ± 0.95 vs (6.76 ± 0.98); diastolic blood pressure (kPa) :( 9.96 ± 0.66) VS (10.28 ± 0.73). The activities of FGP and PTP in DM group were significantly higher than those in NT group (FG (Mmol·L -1) :( 10.03 ± 2.01) vs (5.16 ± 0.70), P <0.001; PTP activity (U) :( 8.40 ± 1. 99) vs (6.17 ± 2.84), P <005). The level of magnesium in erythrocytes in DM group was significantly lower than that in NT group (5.48 ± 0.66) vs Mg (umol · g -1)
