研究目的:

以寒冷地区T1DM为研究对象,在居家使用环境下,探索混合闭环胰岛素输注系统和传统胰岛素泵联合CGM治疗相比的安全性及有效性。研究中在寒冷环境暴露下收集血糖和治疗信息,探索寒冷环境下患者的血糖波动变化,探索闭环系统应用于寒冷地区T1DM患者治疗的未来优化方向。  

Objectives of Study:

This study aims to evaluate the safety and efficacy of hybrid closed-loop (HCL) insulin delivery systems compared to conventional insulin pump therapy integrated with continuous glucose monitoring (CGM) for patients with type 1 diabetes mellitus (T1DM) in real-world home settings in cold regions. By collecting glycemic and therapeutic data during cold exposure periods, the investigation will analyze the unique patterns of glucose variability under these environmental conditions. Finally, the findings will identify future optimization strategies for applying closed-loop technology in managing T1DM in cold climates.

随机方法(请说明由何人用什么方法产生随机序列):

将所有入组受试者进行统一编号,为1~20号。可查阅随机数字表,从表中的开始处或末尾处,或表的中间任何一点选择一个随机数字,用一把直尺以选择的这个随机数字为支点,向上或向下划一条直线或斜线,按顺序取线上的20个随机数字(数字不够可翻页或另取),一组命名为混合闭环胰岛素输注系统组,另一组命名传统胰岛素泵联合CGM治疗组,那么随机数为奇数的分到混合闭环胰岛素输注系统组,偶数的分到传统胰岛素泵联合CGM治疗组。

Randomization Procedure (please state who generates the random number sequence and by what method):

All the enrolled subjects were uniformly numbered from 1 to 20. You can refer to the random number table. Select a random number from the beginning or end of the table, or any point in the middle of the table. Use a ruler to draw a straight or diagonal line upward or downward with this selected random number as the fulcrum. Take 20 random numbers on the line in sequence (if the number is insufficient, you can turn the page or take another number). One group is named the mixed closed-loop insulin infusion system group. Another group was named the traditional insulin pump combined with CGM treatment group. Then, those with odd random numbers were assigned to the mixed closed-loop insulin infusion system group, and those with even numbers were assigned to the traditional insulin pump combined with CGM treatment group.
