摘要
目的 探讨住院糖尿病患者馒头餐耐量试验（SBMTT）期间持续葡萄糖监测（CGM）值和静脉血浆葡萄糖（VPG）值的相关性和差异性。方法 选取自2022年2月至2024年3月于山东省立医院内分泌科住院糖尿病患者116人为研究对象，分别于空腹及餐后30、60、120、180min采集VPG、CGM数据。结果 CGM与VPG整体相关系数为0.968（P<0.001），呈极强相关性，空腹状态下两者差距最小，差距与血糖浓度成正比，120min血糖达最高值。结论 CGM能准确反映住院糖尿病患者VPG变化趋势，但监测值普遍低于VPG，高血糖状态下差异更显著。

Abstract
Objective To explore the correlation and difference between continuous glucose monitoring (CGM) values and venous plasma glucose (VPG) values in hospitalized patients with diabetes during the steamed bread meal tolerance test (SBMTT). Methods A total of 116 hospitalized patients with diabetes who were admitted to the Department of Endocrinology, Shandong Provincial Hospital from February 2022 to March 2024 were selected as the research subjects. VPG and CGM data were collected respectively in the fasting state and at 30, 60, 120, and 180 minutes after meals. Results The overall correlation coefficient between CGM and VPG was 0.968(P<0.001), indicating an extremely strong correlation. The difference between the two was the smallest in the fasting state, and the difference was proportional to the blood glucose concentration. The blood glucose reached the highest value at 120 minutes after meals. Conclusion CGM can accurately reflect the changing trend of VPG in hospitalized patients with diabetes, but the monitored values are generally lower than VPG, and the difference is more significant in the state of hyperglycemia.
