Abstract:
ObjectiveTo investigate the correlation between glucose excursions and oxidative stress in the elderly type 2 diabetic patients. MethodsFifty five elderly type 2 diabetic patients (32 males and 23 females) were recruited. All the patients were submitted to continuous glucose monitoring system (CGMS) for three days. According to the result of CGMS monitoring ,the patients were divided into two groups: high glucose excursion group (30 cases) and low glucose excursion group (25 cases). In high glucose excursion group, the therapy was adjusted for 4 weeks based on the CGMS monitoring. After the treatments, the specimens of blood were collected again to detect the related indexes. Results(1) There were no differences in age, blood pressure, fasting blood glucose and glycosylated hemoglobin between the two groups (all P>0.05). The stardard deviation of blood glucose was higher, and the maximun and average amplitude of glycemic excursion were significantly lower in high glucose excursion group than in low glucose excursion group (t= 5. 4620,5. 9416,3. 8281, all P<0.05) ;(2) Compared with low glucose excursion group, plasma concentration of 8-iso-PGF2a was obviously higher in high glucose excursion group[(57.56 ± 3.86)ng/L vs.(34. 21±3. 82) ng/L, t= 18. 221, P=0. 0000)] . (3) Stepwise regression analysis showed that the standard deviation of blood glucose was involved in regression model (β= 1. 959, P= 0. 013).ConclusionsIn elderly patients with type 2 diabetes mellitus, glucose excursion is related with oxidation stress, which suggests that the glucose excursion may be the risk factor for oxidation stress.
