摘    要:目的 评估实时动态血糖监测对血糖波动的影响.方法 2010年1月至2012年12月,选取住院胰岛素治疗的2型糖尿病患者122例,按随机数字表法分组为传统动态血糖监测(传统组,n=61)和实时动态血糖监测(实时组,n=61).进行72 h持续血糖监测,安装当天为设备调试日(d0),其后第1天(d1)和第2天(d2)为观察时限.传统组每日3次根据指尖末梢血糖调整血糖;实时组每日3次根据实时显示血糖曲线,调整降糖,并设定高低血糖报警界限.统计分析组内(d1和d2)和组间平均血糖波动幅度(MAGE)、平均血糖(MBG)、血糖标准差(SDBG)、日间血糖平均绝对差(MODD)、日内最大血糖波动幅度(LAGE)和低血糖情况.组间比较采用两独立样本均数比较t检验,计数资料采用x2检验.结果 (1)组内比较:实时组d1与d2的MAGE、MBG、SDBG、LAGE分别为(5.3±3.2)比(4.2±2.1)、(8.6±1.7)比(8.2±1.5)、(2.1±0.9)比(1.8±0.7)、(8.6±3.3)比(7.5±2.8)mmol/L(F=9.797、5.852、20.625、11.057,均P<0.05),低血糖持续时间为40(32.5 ~135) min比25(15 ~ 40) min(Z=2.456,P<0.05).传统组d1与d2的MAGE、MBG、LAGE差异均无统计学意义(F=0.229、0.246、0.635,均P>0.05);SDBG为(2.4±1.1)比(2.2±1.0) mmol/L(F=5.615,P<0.05).(2)组间比较:实时组和传统组d1、d2MAGE、LAGE差值之间的比较分别为0.7(-0.3 ~2.0)比0(-1.0~1.5)、0.9(-0.7~2.1)比0.1(-2.5 ~1.9)(Z值分别为2.002、2.023,均P<0.05);组间MODD比较1.8(1.3 ~2.6)比2.1(1.4~2.9) mmol/L(Z=1.572,P>0.05).结论 依据实时动态血糖监测,及时调整降糖策略,能减少血糖波动,使血糖更稳、更快达标.

Abstract:Objective To evaluate the effects of Real-Time Continuous Glucose Monitoring in blood glucose fluctuation.Methods One hundreds and twenty-two type 2 diabetes mellitus (T2DM) inpatients who were using insulin were randomly divided into continuous glucose monitoring system (CGMS) group (n =61) and real time CGMS (RT-CGMS) group (n =61).The first day was equipment testing day (d0).The second and third days were observation time (d1 and d2).The CGMS group control blood glucose by finger stick glucose,while the RT-CGMS group by real-time blood glucose curve.Setup the high and low glucose alarm of RT-CGMS.The mean amplitude of glycemic excursions (MAGE),mean blood glucose (MBG),standard deviation of blood glucose(SDBG),absolute means of daily differences(MODD),large amplitude of glycemic excursions(LAGE) and hypoglycemia were calculated within each group and between the two groups.Results (1) Intragroup comparison:RT-CGMS group:the MAGE,MBG,SDBG and LAGE of d1 andd2were (5.3±3.2) vs (4.2±2.1),(8.6±1.7) vs (8.2±1.5),(2.1 ±0.9) vs (1.8±0.7),(8.6 ± 3.3) vs (7.5 ± 2.8) mmol/L(F = 9.797,5.852,20.625,11.057,respectively,both P 〈 0.05),the duration of hypoglycemia was 40 (32.5-135) vs 25 (15-40) min (Z =2.456,P 〈 0.05).CGMS group:In addition to SDBG,there was no significance difference in MAGE,MBG and LAGE (F =0.229,0.246,0.635,both P 〉 0.05).(2) Intergroup comparison of the difference between d1 and d2:the MAGE and LAGE were0.7(-0.3-2.0)vs0(-1.0-1.5),0.9(-0.7-2.1) vs0.1(-2.5-1.9) mmo]/L (Z=2.002,2.023,respectively,both P〈0.05);MODD was 1.8(1.3-2.6)vs 2.1 (1.4-2.9) mmol/L(Z =1.572,P 〉 0.05).Conclusion Making the blood glucose readjustment plan by RT-CGMS could reduce blood glucose fluctuation in a short time.
