【摘要】 目的 评价2型糖尿病（type 2 diabetes mellitus，T2DM）患者动态血糖监测（continuous glucose monitoring，CGM）的准确性及其相关因素。 方法 2009年1月—2010年1月共纳入患者530例，其中口服降糖药治疗者和胰岛素强化治疗者各265例。应用动态血糖监测系统（美国Medtronic MiniMed公司）连续监测3 d，同时每天输入4次指尖血糖值（self-monitoring of blood glucose，SMBG）进行校正。用直线回归分析CGM值与SMBG的相关性，用Clarke误差表格分析一致性，用平均绝对差（mean absolute relative difference，MAD）评价准确性，并分析MAD的相关因素。 结果 ①共收集到6 350对CGM值[（9.66±3.54） mmol/L]与SMBG值[（9.64±3.38） mmol/L]，两者差异无统计学意义（Pgt;0.05）。Pearson相关性分析显示，两者呈正相关（r=0.959，Plt;0.001）。②Clarke误差表格分析显示:99.89%的点位于A区和B区，其中92.37%血糖值位于A区，7.72%位于B区，其余7对（0.11%）位于D区。③总体MAD值为7.2%（5.5%~9.5%），通过分析每天的MAD值见到，随着监测时间的延长，CGM结果的MAD值逐渐降低，而准确性逐渐升高。 ④胰岛素强化治疗组患者MAD值高于口服药治疗组患者（Plt;0.05），多元逐步回归分析显示，MAD值与糖化血清白蛋白水平呈独立负相关（β=-0.134， Plt;0.01），与胰岛素强化治疗呈独立正相关（β=0.117， Plt;0.05）。 结论 ①动态血糖与毛细血管血糖具有良好的相关性、一致性及准确性。 ②CGM结果的准确性除了受监测时间的影响外，还可能与患者的降糖治疗方案有关。【Abstract】 Objective To assess the accuracy of continuous glucose monitoring (CGM) for patients with type 2 diabetes mellitus (T2DM), and its correlated factors. Methods From January 2009 to January 2010, 530 patients with T2DM were enrolled in this study, including 265 subjects taking oral hypoglycemic agents and the other 265 subjects taking intensive insulin treatment. All the subjects underwent CGM (American Medtronic MiniMed) for three days. Meanwhile, capillary glucose values through self-monitoring of blood glucose (SMBG) were inputted four times a day for adjustment. The correlation of CGM value and capillary glucose value was analyzed by linear regression method. The consistency was analyzed by Clarke error grid. Mean absolute relative difference (MAD) was used to assess accuracy and correlated factors of MAD were also analyzed. Results ① A total of 6 350 pairs of CGM and SMBG values were collected [(9.66±3.54) mmol/L vs. 9.64±3.38) mmol/L,Pgt;0.05]. Pearson correlation analysis showed that CGM value was positively correlated with SMBG value (r=0.959,Plt;0.001). ② Clarke error grid demonstrated that 99.89% of paired SMBG-CGM values were located in zone A and zone B and the remaining seven pairs (0.11%) of glucose values were located in zone D. ③ The overall MAD value was 7.2% (5.5%-9.5%). According to the analysis of daily MAD value, MAD value decreased, while accuracy elevated gradually with monitoring time. ④ MAD value of intensive insulin treatment group was higher than that of the oral hypoglycemic agent treatment group (Plt;0.05). And stepwise multiple regression analysis indicated that MAD value had negative correlation with glycated albumin level (β=-0.134, Plt;0.01) and positive correlation with intensive insulin treatment (β= 0.117,Plt;0.05). Conclusions ① The results of CGM are accurate, and have good correlation and consistency with capillary glucose. ② Besides monitoring time, the accuracy of continuous glucose monitoring may be also associated with hypoglycemic treatment strategy.
ObjectiveTo observe expre with ssions of insulin receptor substrate 1(IRS-1) and ubiquitin-protein in skeletal muscle of non-obese rats with type 2 diabetes mellitus following gastric bypass operation (GBP), and to investigate possible mechanism of GBP in improving insulin resistance. MethodsMale GK rats were randomly divided into diabetic operation group (DO group), diabetic sham operation group (DSO group), and diabetic control group (DC group), 8 rats in each group; besides 8 male Wistar rats were served as normal control group (NC group). Fasting body weight (FBW), fasting plasma glucose (FPG), and fasting insulin (FINS) were measured respectively before operation and on week 1, 2, 4 and 8 after operation. Homeostasis model-insulin resistant (HOMA-IR) index was calculated respectively before operation and on week 8 after operation. The expressions of IRS-1 protein and ubiquitin-protein in skeletal muscle were detected by using Western blot method on week 8 after operation. Results① Compared with the preoperative levels, the FBWs on week 1, 2, and 4 after operation markedly decreased (P < 0.05), but it recovered to the preoperative level on week 8 after operation (P > 0.05) in the DO group; which in the DSO group decreased on week 1 after operation (P < 0.05) and then increased on week 4 after operation (P < 0.05); which in the DC group or the NC group increased continuously and had a significant difference on week 8 after operation (P < 0.05).② The FPGs in the DO, DSO and DC groups were significantly higher than those of the NC group before operation (P < 0.05), which in the DO group decreased from (9.10±0.98) mmoL/L before operation to (5.70±0.91) mmol/L on week 8 after operation (P < 0.05) and were significantly lower than those of the DSO group or the DC group on week 2, 4, and 8 after operation (P < 0.05); which in the DC group, DSO group and NC group had no obviously changes between before and after operations (P > 0.05). ③ The FINS had no significant differences among these four groups before operation (P > 0.05), which in the DO group obviously increased[(9.64±1.59) mU/L] on week 2 after operation (P < 0.05) and then obviously decreased[(6.58±1.05) mU/L] on week 8 after operation (P < 0.05) and significantly lower than those of the DSO group or the DC group on week 8 after operation (P < 0.05), while which had no significant difference between before and after operations in the DSO group, the DC group, or the NC group (P > 0.05). ④ The HOMA-IR index in the DO, DSO or DC group was significantly higher than that of the NC group before operation (P < 0.05), which in the DO group markedly decreased from 3.18±0.50 before operation to 1.96±0.63 on week 8 after operation (P < 0.05) and significantly lower than that of the DSO group or the DC group on week 8 after operation (P < 0.05), while which had no significant difference between before and after operations in the DSO group, the DC group, or the NC group (P > 0.05). ⑤ The expression of IRS-1 protein in the DO group was significantly higher than that in the DSO group (P < 0.05) or the DC group (P < 0.05) on week 8 after operation. While there was no significant difference between the DSO and the DC group after operation (P > 0.05). ⑥ Compared with the NC group, the expression of ubiquitin-protein was significantly increased in the DO group, the DSO group, or the DC group (P < 0.05). Compared with the DSO group or the DC group, the expression of ubiquitin-protein was significantly decreased in the DO group on week 8 after operation (P < 0.05), especially it was most obvious near the molecular weight of 180×103. While there was no significant difference between the DSO group and the DC group after operation (P > 0.05). ConclusionsExpression of IRS-1 protein in skeletal muscle insulin signaling pathway in type 2 diabetes mellitus rats following GBP is increased, it might be associated with decreasing ubiquitin-protein level in skeletal muscle, thus reduces the IRS-1 ubiquitin-degradation, increase insulin sensitivity, and improve insulin resistance of skeletal muscle.
ObjectiveTo systematically review the correlation between type 2 diabetes mellitus (T2DM) and the risk of kidney cancer. MethodsPubMed, EMbase, Web of Science, CBM, VIP and CNKI databases were electronically searched to collect cohort studies on the association between T2DM and kidney cancer from inception to August 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis then performed by using Stata 15.0 software. ResultsA total of 17 cohort studies involving 2 003 165 T2DM patients were included. The results of meta-analysis showed that patients with T2DM had a higher kidney cancer risk than controls (RR=1.51, 95%CI 1.39 to 1.64, P<0.001). Subgroup analysis showed that the incidence of kidney cancer in T2DM patients was higher in different gender, region, population, follow-up time, diabetes assessment method and other subgroups. ConclusionsCurrent evidence shows that T2DM is a risk factor for kidney cancer.

Methods A total of 107 patients with type 2 diabetes mellitus from June 2007 to July 2008 were randomly divided into two groups: 54 patients in group A were injected with insulin lispro 75/25 [0.5-0.7 U/(kg•d)], twice per day, 10 minutes before each breakfast and dinner, and another 53 patients in group B were injected with human insulin humulin 70/30 [0.7-1.0 U/(kg•d)], twice per day, 30 minutes before each breakfast and dinner. The daily insulin dosage, level of blood glucose, body mass and the incidence of low blood sugar in the two groups were observed. Results Two weeks after the treatment, the level of FBG decreased from (15.4±3.1) mmol/L to (6.5±1.4) mmol/L (Plt;0.05), and the level of PBG-2h decreased from (22.2±6.5) mmol/L to (9.23±2.51) mmol/L (Plt;0.05) in group A; the level of FBG decreased from (14.9±3.0) mmol/L to (6.7±1.7) mmol/L (Plt;0.05), and the level of PBG-2h decreased from (21.7±7.3) mmol/L to (11.10±2.73) mmol/L (Plt;0.05) in group B. Three months after the treatment, the level of HbA1c in group A decreased apparently, which differed much from that in group B (Plt;0.05). The daily dosage of insulin in group A was lower than that in group B (Plt;0.05); the differences in changes of body mass and the incidence of hypoglycemia between the two groups were not significant (Pgt;0.05).

The cognitive impairment of type 2 diabetes patients caused by long-term metabolic disorders has been the current focus of attention. In order to find the related electroencephalogram (EEG) characteristics to the mild cognitive impairment (MCI) of diabetes patients, this study analyses the EEG synchronization with the method of multi-channel synchronization analysis--S estimator based on phase synchronization. The results showed that the S estimator values in each frequency band of diabetes patients with MCI were almost lower than that of control group. Especially, the S estimator values decreased significantly in the delta and alpha band, which indicated the EEG synchronization decrease. The MoCA scores and S value had a significant positive correlation in alpha band.
ObjectiveTo observe the influence and interaction of duodenal jejunal bypass (DJB) and hepatic branch of vagus on glucose metabolism, and fasting serum glucagon like peptide-1 (GLP-1), peptide YY (PYY) in non-obese rat with type 2 diabetes mellitus (T2DM). MethodsForty non-obese Wistar rats (GK) with T2DM were randomly divided into four groups: sham operation group (SO group), sham operation plus hepatic branch of vagus resection (HBVR) group (SO+HBVR group), DJB group, and DJB+ HBVR group. The changes of preoperative and postoperative body weight, fasting blood glucose level, fasting serum insulin level, fasting serum GLP-1 and PYY contents among four groups were observed. ResultsIn the DJB group, the postoperative body weight and fasting blood glucose level were decreased significantly (P < 0.05) and the fasting insulin level, fasting serum GLP-1 and PYY contents were increased significantly (P < 0.05) as compared with the preoperative corresponding values in the same group, and it was found that the hepatic branch of vagus could more lastingly maintain postoperative lower body weight (P < 0.05), improve the level of insulin (P < 0.05), increase the fasting serum GLP-1 and PYY contents (P < 0.05) as compared with the DJB+HBVR group. ConclusionDJB could improve glucose metabolism effect of GK rats, the hepatic branch of vagus might play a role in it, too.
