AIM:TodetecthemoglobinA1c(HbA1c)andparametersofbloodglucosefluctuationinChinesenewlydiag-nosed type 2 diabetes mellitus (T2DM) patients, and further to specify the factors that were related to mean blood glucose (MBG) in this population.METHODS:Newly diagnosed T2DM patients (n=90) from 4 hospitals in Guangdong province were enrolled, and subjected to 3 d continuous glucose monitoring (CGM) after testing for HbA1c and other laboratory tests.Blood glucose data collected during CGM were used to calculate MBG and parameters of blood glucose fluctuation.RESULTS: Correlation analysis revealed that MBG was significantly related to all parameters of blood glucose fluctuation, HbA1c, fast plasma glucose ( FPG) and 2 h postprandial glucose (P<0.01), but not to sex, age or blood lipid profile.Further analysis utilizing step-wise general linear model showed that HbA1c, absolute means of daily difference ( MODD) , difference between maximal and minimal glucose ( DMMG) and FPG had the strongest relation to MBG.CONCLUSION: Factors affecting MBG of the newly diagnosed T2DMpatients in our country include HbA1c, FPG, DMMG and MODD, and thus it may be prone to misleading results that only HbA1c is applied to estimate MBG in this population.

Objective In this study, we aimed to translate and revise the Summary of Diabetes Self-Care Activities( SDSCA) and the Confidence In Diabetes Self-care( CIDS) scales, to test the reliability and validity of the two scales in Chinese adult type 1 diabetes( T1D) patients. Methods In the first step, Chinese versions( C-SDSCA and C-CIDS) were developed conceptually equivalent to the English versions. And the investigation was conducted in 100 patients from Guangdong T1D Translational Medicine Study. 15 of them were randomly chosen to be retested 4 weeks later. Cronbach's α were used to assess reliability, and factor analysis to its validity. The relationship between scores of C-SDSCA and C-CIDS were analyzed using Spearman correlation analysis. Results The overall Cronbach's α of C-SDSCA was 0.72 and the retest reliability was 0.95( sub-scale:0.67-1.00) . 4 common factors were extracted by factor analysis, and the cumulative contribution was 87.39％. As for C-CIDS, the general Cronbach's α was 0.84 and the retest reliability was 0. 70 ( sub-scale: 0. 49-0. 86 ) . 6 common factors were extracted and the cumulative contribution was 75.41％. The score of the two scales was positively related(r=0.61, P<0.01). Conclusion The revised C-CIDS and C-SDSCA scales turn out to have good reliability and validity, and can be used as instruments to assess diabetes self-management efficacy and self-care activities of Chinese adult T1D patients.

Background: Both type 1 diabetes mellitus (T1DM) and metabolic syndrome (MetS) are associated with an elevated risk of morbidity and mortality yet with increasing heterogeneity. This study primarily aimed to evaluate the prevalence of MetS among adult patients with T1DM in China and investigate its associated risk factors, and relationship with microvascular complications. Methods: We included adult patients who had been enrolled in the Guangdong T1DM Translational Medicine Study conducted from June 2010 to June 2015. MetS was defined according to the updated National Cholesterol Education Program criterion. Logistic regression models were used to estimate the odds ratio (OR) for the association between MetS and the risk of diabetic kidney disease (DKD) and diabetic retinopathy (DR). Results: Among the 569 eligible patients enrolled, the prevalence of MetS was 15.1%. While female gender, longer diabetes duration, higher body mass index, and glycosylated hemoglobin A1c (HbA1c) were risk factors associated with MetS (OR, 2.86, 1.04, 1.14, and 1.23, respectively), received nutrition therapy education was a protective factor (OR, 0.46). After adjustment for gender, age, diabetes duration, HbA1c, socioeconomic and lifestyle variables, MetS status was associated with an increased risk of DKD and DR (OR, 2.14 and 3.72, respectively; both P<0.05). Conclusion Although the prevalence of MetS in adult patients with T1DM in China was relatively low, patients with MetS were more likely to have DKD and DR. A comprehensive management including lifestyle modification might reduce their risk of microvascular complications in adults with T1DM.

Background::Data on the glycemic profile of pregnant women with gestational diabetes mellitus (GDM) during the perinatal period are sparse. This study described the intrapartum and early postpartum glucose profiles among pregnant women with GDM, and analyzed factors potentially affecting glycemic parameters during the period.Methods::This was a prospective observational study conducted from March 2020 to November 2021. Pregnant women with GDM receiving lifestyle interventions alone during pregnancy and matched women with non-diabetic pregnancies (NDPs) were enrolled from among patients admitted to the obstetrics department for childbirth. Glucose monitoring was performed via a flash glucose monitoring (FGM) system on admission, and glucose readings during labor and early postpartum were analyzed. The clinical characteristics and FGM-based parameters of participants in the two groups were compared.Results::A total of 124 participants (mean age: 29.5 ± 3.5 years, 92 [74.2%] primipara) were included in the final analysis. A total of 17,571 glucose readings were retrieved. There were no significant differences in clinical characteristics between the GDM ( n = 60) and NDP ( n = 64) groups. The average glucose level was 92.2 mg/dL, and the level was higher in the GDM group (95.5 ± 12.1 mg/dL vs. 89.1 ± 13.4 mg/dL, P = 0.008) during the intrapartum and early postpartum periods. The data were split into the intrapartum period (from the start of labor to delivery of the placenta) and the early postpartum period (within 24 h after placental delivery) for analysis. During intrapartum, women with GDM exhibited glycemic profiles and fluctuations similar to those in the NDP group. However, women with GDM had higher postpartum glucose levels (97.7 ± 13.4 mg/dL vs. 90.8 ± 15.3 mg/dL, P = 0.009), a longer time spent >140 mg/dL (8.7 ± 9.3% vs. 5.9 ± 10.3%, P = 0.011), and greater glycemic fluctuations than those with NDP. Postpartum hyperglycemia in GDM might be associated with high parity and postprandial glucose abnormalities in GDM screening tests. Conclusion::Compared to those with normoglycemia, pregnant women with GDM receiving lifestyle interventions alone had similar intrapartum glucose profiles but higher early postpartum glucose levels and greater glucose variability, providing evidence for modification of the current perinatal glucose monitoring strategy for GDM.Trial Registration::ChiCTR.org.cn, ChiCTR2000030972

Objective:To explore the effect of comprehensive moxibustion with Huolong cupping in patients with lung-spleen qi deficiency type allergic rhinitis.Methods:This study was a randomized controlled trial. From October 2022 to April 2023, convenience sampling was used to select 66 patients with lung-spleen qi deficiency type allergic rhinitis who visited the Otolaryngology Head and Neck Clinic of Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine as the research subject. The patients were randomly divided into an experimental group ( n=33) and a control group ( n=33). Both groups received routine oral Chinese medicine treatment. On the basis of routine treatment, the experimental group performed comprehensive moxibustion with Huolong cupping on the meridians of the Du meridian and bladder meridian. This study compared the scores of Nasal Airway Resistance (NAR), Total Nasal Symptom Score (TNSS), Visual Analogue Scale (VAS), and Chinese version of Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) between two groups of patients before and after intervention. Results:Eventually 30 patients in each of the experimental group and control group completed the study. After intervention, the NAR score of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05). Repeated measures analysis of variance showed that with the increase of treatment time, the TNSS, VAS, and RQLQ scores of the experimental group were lower than those of the control group with statistical differences ( P<0.05), and the time effect, inter group effect, and interaction effect were statistically significant ( P<0.05) . Conclusions:Huolong cupping comprehensive moxibustion can reduce nasal resistance, meliorate nasal symptoms and accompanying nasal symptoms, and improve the quality of life of patients.

Objective:To explore the correlation between blood glucose level and parental education level in children with type 1 diabetes mellitus (T1DM) based on mobile health APP.Methods:The data of T1DM children enrolled in China′s T1DM registration management program and registered to use TangTangquan ? were collected, as well as the blood glucose monitoring information uploaded quarterly after registration. Children were divided into low education group (middle school or below) and high education group (junior college or above) according to their parents′ education level. Blood glucose levels were compared between the two groups at different time points. Spearman correlation analysis and multivariate logistic regression analysis were used to evaluate the correlation between blood glucose level and parents′ education level in children with T1DM. Results:A total of 2 263 eligible children with T1DM were included and 1 246 were female (55.1%). The median age was 7.9(4.4, 11.4)years and T1DM duration was 0.07(0.02, 0.46)years. Among them, 1 513 cases were in the low-education group while 750 cases were in the high-education group. Within three years after registration, the glucose levels of each interval in the low-education group were increasing gradually (all P<0.05 except post-breakfast glucose). The glucose levels of each interval in the high-education group in the third year were lower than those in the low-education group (all P<0.05 except nocturnal glucose). The result of multivariate logistic regression analysis showed that after the adjustment of factors including T1DM duration and treatment, parental educational levels were still the separate related factors of premeal glucose, bedtime glucose and nocturnal glucose (premeal glucose: OR=0.385, 95% CI: 0.164-0.874, P=0.025; bedtime glucose: OR=0.444, 95% CI: 0.204-0.949, P=0.038; nocturnal glucose: OR=0.226, 95% CI: 0.582-0.747, P=0.020). Conclusions:The blood glucose levels of children with T1DM were negatively associated with parental educational levels. It is suggested that parental educational levels should be taken into consideration in the management of T1DM for children.

Objective: To detect the viscoelasticity of carotid artery in healthy volunteers using ultrasonic shear wave dispersion (SWD) technique, and explore the feasibility and influencing factors for SWD parameters. Methods: Forty-five healthy volunteers were recruited and divided into elder group (≥50 years old) and younger group (<50 years old) according to the age. The carotid arteries were examined by SWD at systole, axial elastic modulus (SWE_R) and viscous index (SWD_R) were obtained. The pulse wave velocity (PWV), a carotid artery circumferential elastic parameter was obtained and considered as the reference indicator. The difference of SWE_R, SWD_R and PWV were compared between two groups; and the correlation between them were analyzed by Pearson analysis, respectively. Results: ①Compared with the younger group, the carotid PWV increased, while SWE_R and SWD_R decreased in the elder group(all P<0.05). ②In all subjects, SWE_R was negatively correlated with PWV (r=-0.256, P<0.05). In the elder group, SWE_R was negatively correlated with systolic blood pressure (r=-0.357, P<0.05), and SWD_R was negatively correlated with PWV (r=-0.393, P<0.05). In the younger group, SWD_R was positively correlated with systolic blood pressure (r=0.366, P<0.05). Conclusions Compared with the elder group, the carotid viscoelasticity was higher in young people, and it is correlated with PWV. SWD can evaluate carotid viscoelasticity, and contribute to better understanding of its tissue characteristics.

Objective: To evaluate the effect of mobile application (APP) based interactive peer support on glycemic control in patients with type 1 diabetes mellitus (T1DM). Methods: The data of the present study were from the largest mobile APP platform for patients with T1DM in China, Tangtangquan. Patients with T1DM who has registered in the APP for at least 1 year and had completed data entry were recruited. According to the monthly interaction index during the first year of APP registration (including four indicators: praise, comment, posting and collection), the eligible patients were divided into the high-interaction group and the low-interaction group. The changes from baseline of self-blood glucose monitoring frequency (SMBG), glycosylated hemoglobin (HbA1c), incidence of hyperglycemia and incidence of hypoglycemia were compared between the two groups after one year of using the APP. Results: A total of 238 patients with T1DM with an age of (27±8) years were included. Among them, 77.3% (184/238) were female. The baseline SMBG [the low-interaction group (1.71±1.14) times/day vs. the high-interaction group (1.82±1.15) times/day] and HbA1c [the low-interaction group (6.72±0.99)% vs. the high-interaction group (6.76±1.04)%] were comparable between the two groups. After one year use of the APP, the frequency of SMBG in the high-interaction group was significantly higher than that in the low-interaction group [ΔSMBG (0.59+2.06) times/d vs. (0.08+1.69) times/d, t=4.280, P=0.04), and the reduction of HbA1c was more obvious in the high-interaction group [ΔHbA1c (-0.40+1.10)% vs. (-0.06+1.13)%, t=5.651, P=0.018] than in the lower-interaction group. The incidence of hyperglycemia in the high-interaction group was significantly lower than that in the low-interaction group [13.19(6.22,23.19)% vs. 17.69(10.56,30.49)%, Z=2.850, P=0.005]. There was no significant difference in the incidence of hypoglycemia between the two groups [4.62(2.14, 8.03)% vs. 4.83(2.06, 8.87)%, Z=1.276, P=0.204]. The correlation analysis showed that interaction index was significantly associated with the reduction of HbA1c and incidence of hyperglycemia. Conclusion Participation in interactive peer education via mobile APP may be beneficent for glycemic control in patients with T1DM.
