Methods：The Pro12Ala polymorphism in PPARγ2 was determined by polymerase chain reactionrestriction fragment length polymorphism (PCRRELP) in 177 subjects with primary hypertension of the Han people in Chengdu of China, including 65 subjects with fasting blood glucose (FBG)lt;5.6 mmol/L and 112 subjects with FBG≥5.6 mmol/L; the clinical characteristics including height, weight, OGTT(0h and 2h) of the subjects were detected and the realationship between the Pro12Ala polymorphism and the clinical characteristics were analysed. Results: The allele frequencies in the group with FBGlt;5.6 mmol/L and FBG≥5.6 mmol/L were 0.333, 0.602 for Pro and 0.034, 0.031 for Ala. The genotype frequencies were 0.299, 0.571 for PP and 0.068, 0.062 for PA, and there was no AA. In the group with BMIlt;25, the Pro12Ala polymorphism was associated with FBG （P=0.029). the Ala allele had a negative relationship to the FPG and insulin resistance index (IRI) (Plt;0.05).Conclusion: The data showed that the Pro12Ala polymorphism was associated with FBG., and The allele Ala probably had benefits to glycometabolic disturbance in patients with primary hypertension by declining insulin resistance.
ObjectiveTo explore the relationship between blood glucose variability index and persistent organ failure (POF) in acute pancreatitis (AP). MethodsWe prospectively included those patients who were diagnosed with AP with hyperglycemia and were hospitalized in the West China Center of Excellence for Pancreatitis of West China Hospital of Sichuan University from July 2019 to November 2021. The patients were given blood glucose monitoring at least 4 times a day for at least 3 consecutive days. The predictive value of blood glucose variability index for POF in patients with AP was analyzed. ResultsA total of 559 patients with AP were included, including 95 cases of POF. Comparing with those without POF, patients with AP complicated by POF had higher levels of admission glucose (11.0 mmol/L vs. 9.6 mmol/L), minimum blood glucose (6.8 mmol/L vs. 5.8 mmol/L), mean blood glucose (9.6 mmol/L vs. 8.7 mmol/L), and lower level of coefficient of variation of blood glucose (16.6 % vs. 19.0 %), P<0.05. Logistic regression analyses after adjustment for confounding factors showed that the risk of POF increased with the increase of admission glucose [OR=1.11, 95%CI (1.04, 1.19), P=0.002], minimum blood glucose [OR=1.28, 95%CI (1.10, 1.48), P=0.001] and mean blood glucose [OR=1.18, 95%CI (1.04, 1.33), P=0.010]; with the higher level of coefficient of variation of blood glucose [OR=0.95, 95%CI (0.92, 0.99), P=0.021], the risk of POF decreased. The results of area under the curve (AUC) of the receiver operator curves showed that AG [AUC=0.787, 95%CI (0.735, 0.840)] had the highest accuracy in predicting POF, with sensitivities of 60.0% and specificities of 84.7%. ConclusionHigh admission glucose, minimum blood glucose, mean blood glucose, and low coefficient of variation of blood glucose were risk factors for the development of POF in patients with hyperglycemic AP on admission.
Objective To investigate the correlation between stress hyperglycemia ratio (SHR) and acute ischemic stroke (AIS) 1-year prognosis, to provide more clinical basis to improve the prognosis of AIS patients and to target and control the influencing factors. MethodsThe patients with AIS diagnosed for the first time and received treatment at the Shijiazhuang Fifth Hospital between May 2019 and January 2022 were retrospectively and continuously included. According to the Modified Rankin Scale score 1-year after the onset of the disease, the patients were divided into a good prognosis group and a poor prognosis group. Also the patients were divided into 2 groups based on the median of SHR. The correlation between SHR and stress blood glucose was analyzed, and the factors affecting the prognosis of AIS patients were identified. The predictive value of SHR and stress blood glucose on the prognosis of AIS patients was compared using receiver operating characteristic. Results A total of 206 patients were included. Among them, there were 125 cases (60.7%) in the good prognosis group and 81 cases (39.3%) in the poor prognosis group. The median SHR (lower quartile, upper quartile) is 1.20 (1.08, 1.33). There were statistically significant differences between the two groups in the scores of the National Institutes of Health Stroke Scale, diabetes history, hypertension history, low-density lipoprotein cholesterol, stress blood glucose, age, SHR and SHR classification (P<0.05). There was no statistically significant difference in the other indicators compared between the two groups (P＞0.05). Stress blood glucose was positively correlated with SHR (7.95±1.78 vs. 1.21±0.19; r=0.294, P<0.001). Multivariate logistic analysis showed that stress blood glucose and SHR were independent factors influencing the 1-year prognosis of AIS patients (P<0.05), and the interaction between SHR and diabetes was not significant (P>0.05) After adjusting for confounding factors, the area under the receiver operating characteristic curve of SHR for the prognosis of AIS patients was higher than that of stress blood glucose [0.682 (0.614, 0.745) vs .0.585 (0.515, 0.653); Z=2.042, P=0.041]. Conclusions SHR and stress blood glucose are independent risk factors for 1-year prognosis in AIS patients. However, SHR has a better predictive value for 1-year prognosis in AIS patients than stress blood glucose. Whether the patient has diabetes or not, the impact of SHR on the prognosis of AIS patients is consistent.
ObjectiveTo explore the prognostic value of fasting blood glucose concentration in patients with newly diagnosed lung cancer.MethodsThe clinical data of 956 patients with lung cancer who were first diagnosed at West China Hospital of Sichuan University between January 2008 and December 2011 were retrospectively analyzed. The patients were followed up for more than 5 years. Using the fasting blood glucose concentration of 6.1 mmol/L as the cut-off value, the patients were divided into the hyperglycemia group and the control group. Kaplan-Meier method was used for survival analysis, and log-rank test was used to analyze the survival of different groups. Univariate and multivariate Cox proportional hazard models were used to evaluate the prognostic variables.ResultsThere were 166 patients in the hyperglycemia group with a 5-year overall survival rate of 23.5%, and 790 patients in the control group with a 5-year survival rate of 30.8%, and the difference between the two groups was statistically significant (P=0.008). Univariate Cox proportional hazard analysis found that blood glucose concentration, gender, age, smoking history, staging, and whether surgery were factors that affected the 5-year survival rate of patients (P<0.05); multivariate Cox proportional hazard analysis showed that blood glucose concentration [hazard ratio (HR)=1.235, 95% confidence interval (CI) (1.013, 1.504), P=0.036], age [HR=1.305, 95%CI (1.110, 1.534), P=0.001], smoking history [HR=1.210, 95%CI (1.033, 1.418), P=0.018], staging [HR=1.546, 95%CI (1.172, 2.040), P=0.002], and whether surgical treatment [HR=0.330, 95%CI (0.257, 0.424), P<0.001] were independent factors which influenced 5-year survival rate. Blood glucose concentration, age, smoking history, and staging were independent risk factors.ConclusionFasting blood glucose concentration is able to be a prognostic factor for patients with newly diagnosed lung cancer.

This article discusses the basic principles of minimally invasive and non-invasive blood glucose testing assays, including urine glucose assays, tear assays, methods of extravasation of tissue fluid, and optical detection methods, etc., focuses on the advantages of minimally invasive and non-invasive blood glucose testing methods and the latest relevant results, and summarizes the current problems of various testing methods and prospects for future development trends.
Objective To investigate the application effect of ndividualized dietary care based on a multidisciplinary collaboration model on glycemic control, neurological recovery, dietary self-management, and satisfaction in stroke patients with abnormal blood glucose. Methods Patients with stroke and abnormal blood glucose admitted to the Department of Neurology, Shangjin Hospital, West China Hospital, Sichuan University between March and October 2024 were enrolled. Using SPSS 26.0 software, a random allocation sequence was generated to divide participants into an observation group and a control group. The control group received comprehensive nursing interventions, while the observation group received additional multidisciplinary collaboration model based individualized dietary care. Both groups were intervened until discharge. Glycemic indicators [glycated albumin (GA), fasting blood glucose (FBG), 2-hour postprandial blood glucose (2hPG)], neurological recovery, dietary adherence, and patient satisfaction were compared pre-intervention and post-intervention (at discharge). Results A total of 112 patients were included, with 56 patients in each group. At the post-intervention stage, GA, FBG and 2hPG in the observation group were lower than those in the control group (P<0.05), and the scores of the Dietary Compliance Scale for Type 2 Diabetes were higher than those in the control group (P<0.05). Except for admission (3.27±0.86 vs. 3.25±0.90, P＞0.05), the modified Rankin Scale scores of the observation group were lower than those of the control group at discharge (3.14±0.86 vs. 3.17±0.86), 30-days follow-up (2.93±0.76 vs. 3.02±0.84), and 90-days follow-up (1.05±0.80 vs.1.43±1.01) (P<0.05). The comparison results within the group showed that, there were significant differences in GA, FBG, 2hPG, modified Rankin Scale scores and Dietary Compliance Scale for Type 2 Diabetes between admission and discharge (P<0.05). The satisfaction rate of the observation group was higher than that of the control group (97.78% vs. 86.76%; χ2=3.877, P=0.049). Conclusion Multidisciplinary collaboration model based individualized dietary care improves short-term glycemic control, promotes long-term neurological recovery, enhances dietary adherence, and increases patient satisfaction in stroke patients with abnormal blood glucose, demonstrating clinical value for widespread application.
On December 11, 2023, the American Diabetes Association (ADA) promulgated the Standards of Care in Diabetes (2024). For a long time, the ADA promulgated the Standards of Care in Diabetes had been regarded as the international guide in the field of diabetes, which has a great reference value for the diagnosis and treatment of diabetes in various countries. The new standard continues to emphasize the transformation of the diagnosis and treatment model from the glucose reduction to the patients, highlighting the importance of reasonable control of glucose, weight management, and improvement of cardiac and renal prognosis as the comprehensive management of diabetes patients, meanwhile continues to affirm the advantages of new hypoglycemic drugs such as glucagon like peptide-1 receptor agonist and metabolic surgery in the comprehensive management of type 2 diabetes mellitus.
The use of non-invasive blood glucose detection techniques can help diabetic patients to alleviate the pain of intrusive detection, reduce the cost of detection, and achieve real-time monitoring and effective control of blood glucose. Given the existing limitations of the minimally invasive or invasive blood glucose detection methods, such as low detection accuracy, high cost and complex operation, and the laser source's wavelength and cost, this paper, based on the non-invasive blood glucose detector developed by the research group, designs a non-invasive blood glucose detection method. It is founded on dual-wavelength near-infrared light diffuse reflection by using the 1 550 nm near-infrared light as measuring light to collect blood glucose information and the 1 310 nm near-infrared light as reference light to remove the effects of water molecules in the blood. Fourteen volunteers were recruited for in vivo experiments using the instrument to verify the effectiveness of the method. The results indicated that 90.27% of the measured values of non-invasive blood glucose were distributed in the region A of Clarke error grid and 9.73% in the region B of Clarke error grid, all meeting clinical requirements. It is also confirmed that the proposed non-invasive blood glucose detection method realizes relatively ideal measurement accuracy and stability.
ObjectiveTo understand the relation between blood glucose regulating hormones and gastric cancer, so as to provide some new ideas for diagnosis and treatment of gastric cancer. MethodBy reviewing and screening relevant domestic and foreign literatures, the latest researches on the relation between blood glucose regulating hormones and gastric cancer were summarized. ResultsThe insulin, glucagon, adrenaline, growth hormone, and the other blood glucose regulating hormones all played the roles in promoting the occurrence and development of gastric cancer. However, glucocorticoids and somatostatin were protective hormones that maintained gastric homeostasis and inhibited the proliferation of gastric cancer cells. ConclusionBlood glucose regulating hormones play some roles in diagnosis and treatment of gastric cancer, but specific mechanisms such as interaction between blood glucose regulating hormones, role of glucose metabolism in biological behavior of gastric cancer, and effect of blood glucose regulating hormones on oncogene initiation are unclear, so prospective clinical control studies still need to be studied.
Objective To investigate the current situation of self-monitoring of blood glucose (SMBG) in patients with type 2 diabetes mellitus (T2DM) in Sichuan province, and to analyze the influencing factors of SMBG, so as to provide evidence for improving the level of SMBG. Methods By the convenience sampling method, 410 patients with T2DM for more than 1 year were selected from 17 hospitals and community health service centers in 7 cities across Sichuan province, and their SMBG was investigated with a questionnaire. Results Among 410 eligible patients, the average frequency of SMBG was 7.3 times per month. There were 268 patients (65.4%) performed SMBG less than 4 times per month, 94 (22.9%) performed 4-15 times per month, 29 (7.1%) performed 6-29 times per month, and 19 (4.6%) performed over 30 times per month. Just 234 patients (57.1%) monitored the HbA1c in the past 6 months. FPG, 2-hour PPG and HbA1c were negatively correlated with the frequency of SMBG. The influencing factors of SMBG were insulin treatment and education. Conlusion The SMBG status in D2TM patients is relatively poor in Sichuan province, and the compliance of SMBG is expected to be improved by enhancing diabetic education.
