Objective:
To analyze current status of physical exercise of primary and middle school students in Henan province, and to explore its relationship with physical fitness.
Methods:
Data on physical exercise and related indicators among 9-18 years old students was retrieved from Henan Provincial Student Physical Fitness and Health Survey in 2019. Physical fitness index (PFI), body mass index (BMI) was calculated. ANOVA was used to compare differences of physical exercise between men and women, urban and rural areas. Correlations between physical exercise with PFI and BMI were evaluated.
Results:
The majority of students had two PE classes per week (41.9%), daily active recess (44.5%), one sports meeting in each school year (46.8%), and half to one hour of physical exercise per day (50.1%). Boys were more likely to exercise than girls, while rural students were more likely to excecise than urban students. The proportion of parents who support sports activities in their spare time was the highest (75.8%), and the proportion of parents who both like sports was the highest (47.3%). PFI was positively correlated with exercise scores and negatively correlated with non exercise scores. BMI was negatively correlated with exercise scores and positively correlated with non exercise scores ( r =0.12, -0.13, -0.20, 0.14, P <0.01).
Conclusion
Physical exercise of primary and middle school students in Henan is satisfactory.Exercise scores are positively correlated with physical fitness, but negatively correlated with BMI.

Objective To assess the effectiveness of a novel mobile health patient management system involving doctors, nurses, and patients ( TRIO mode) on glycemic control and self-monitoring of blood glucose (SMBG) compliance among the type 2 diabetes mellitus ( T2DM) patients using basal insulin standardization treatment in China. Methods From April 2014 to April 2015, 416 hospitals in 110 cities of 30 provinces, municipalities, and autonomous regions across China were selected to participate in the program. A Online-to-Offline ( O2O) integrated mobile health patients management system with mobile terminals for the doctors, nurses, and patients was applied in the program for patient education, follow-up, and data collection. For all the newly recruited patients, the baseline information was collected and a first-day patient education program were provided by a designated nurse. In the 12-week follow-up period, data of basal insulin doses and fasting plasma glucose ( FPG) values were collected from the patients by text messages or tracking phone call by the nurse. The patients also received timely standardized patients health education and glycemic control guidance by participating in thepatient education forum anddoctors' hotline in order to help them achieve the glycemic control goals. Results A total of 102 524 patients using basal insulin treatment were eligible and enrolled in the program. 64 420 patients completed the 12 weeks follow-up and provided at least one FPG value at all five follow-ups. In total, 62. 6% (40 334 / 64 420) of the patients reached the FPG control target(FPG≤7. 0 mmol/ L) at the end of follow-up period. The weekly average FPG for patients with complete SMBG data decreased from 10. 58 mmol/ L to 6. 91 mmol/ L while the FPG control rates increased from 13. 4% to 69. 2% . The weekly average FPG for the patients provided incomplete SMBG data decreased from 10. 54 mmol/ L to 7. 13 mmol/ L while the FPG control rates increased from 13. 6% to 62. 2% . The FPG control rates for the patients provided complete SMBG were 1. 74 times higher than those patients provided incomplete SMBG. Based on a GEE model, the average decline of the FPG and the increase of the FPG control rates were significantly better for patients who provided complete SMBG as compared to the patients with incomplete SMBG data. The results of the multivariate logistic regression analysis showed that factors such as receiving the first-day education, participating in the follow-up patient education forum, and the doctors' hotline were significantly associated with the improvement of the SMBG compliance, the treatment adherence, and the FPG control rates. The SMBG compliance and the treatment adherence for patients who completed first-day education were 1. 68 times and 1. 22 times higher, respectively. For the patients who participated in follow-up education activities, their SMBG compliance and treatment adherence were 3. 17 times and 3. 36 times higher, respectively. Conclusion The innovativeTRIOmobile health patient management mode was feasible and effective for better managing the type 2 diabetes patients initiated on basal insulin treatment in China. Active participation in the first-day education program and the follow-up patient education activities can effectively improve the SMBG compliance and the treatment adherence, and therefore play an important role in helping patient achieving FPG control in a faster manner.

Objective:To establish the normal reference range of atrial septal excursion index (ASEI) and foramen ovale membrane angle in normal fetuses aged 16-40 weeks, and to analyze the correlation between ASEI and foramen ovale membrane angle in normal fetuses.Methods:A total of 378 normal singletons with gestational ages of 16-40 weeks undergoing by fetal echocardiography were selected in the Department of Diagnostic Ultrasound & Echocardiography, Sir Run Run Shaw Hospital, Zhejiang University College of Medicine, from January to June 2021, and 349 fetuses successfully finished all measurements. After all fetuses completed the systematic fetal echocardiography, fetal foramen ovale diameter and foramen ovale membrane angle were measured on the four chamber view. The maximum distance of foramen ovale valve from the base of atrial septum to the free wall of left atrium and the transverse diameter of left atrium were measured, and ASEI was calculated. The differences of ASEI, foramen ovale membrane angle and foramen ovale diameter of the groups with different gestational weeks were compared. The correlations among ASEI, foramen ovale membrane angle and foramen ovale diameter were analyzed by Pearson correlation analysis.Results:All 349 fetuses were divided into 6 groups according to their gestational weeks, including 17 cases at 16-20 weeks, 46 cases at 21-24 weeks, 114 cases at 25-28 weeks, 105 cases at 29-32 weeks, 31 cases at 33-36 weeks and 36 cases at 37-40 weeks. The ± s of ASEI was 0.492 7±0.059 7, 95% CI was 0.486 4-0.499 0, 95% normal reference value range was 0.375 7-0.609 8. Significant differences were found in ASEI among different groups( P<0.05). The ± s of foramen ovale membrane angle was (44.03±5.48)°, 95% CI was 43.46-44.61°, 95% normal reference value range was 33.29-54.78°. Significant differences were found in the foramen ovale membrane angle among different groups( P<0.05). The ± s of foramen ovale diameter was (4.32±1.30)mm, 95% CI was 4.18-4.45 mm, the differences among different groups were significant( P<0.05) and foramen ovale diameter was found increased with the increase of gestational weeks. There was a significant positive correlation between ASEI and foramen ovale membrane angle ( r=0.558, P<0.05). There was no correlation between foramen ovale diameter and ASEI and foramen ovale membrane angle ( r=-0.166, -0.084; all P>0.05). Conclusions:The normal reference ranges of ASEI and foramen ovale valve angle of normal fetuses aged 16-40 weeks was successfully established. These parameters may be useful for evaluating diastolic cardiac function by assessing foramen ovale.

BACKGROUNDSelf-monitoring of blood glucose (SMBG) by individuals with type 2 diabetes (T2D) is crucial for long-term health, yet numerous cultural, economic and health factors can reduce SMBG. Most studies on SMBG adherence have come out of the US and Europe, and their relevance to Asia is unclear. The aims of the present study were to assess the current state of SMBG in China and analyze demographic and diabetes-related characteristics that may influence it.
METHODSIn this multi-center, cross-sectional study, 5 953 individuals with T2D from 50 medical centers in 29 provinces across China filled out a standardized questionnaire that requested information on demographic characteristics, education level, occupation, income, lifestyle risk factors, duration of diabetes, chronic complications, and frequency of SMBG. Respondents were also asked whether their glycosylated hemoglobin (HbA1c) had been checked in the past 6 months. The most recent values for fasting plasma glucose, 2-hour postprandial blood glucose and HbA1c were recovered from medical records.
RESULTSOnly 1 130 respondents (18.98%) performed SMBG with the recommended frequency, while 4 823 (81.02%) did not. In fact, nearly 2 105 (35.36%) reported never performing SMBG. In the subset of 3 661 individuals on insulin therapy, only 266 (7.27%) performed SMBG at least once a day, while 1 210 (33.05%) never performed it. In contrast, 895 of 2 292 individuals (39.05%) on diet/exercise therapy or oral hypoglycemic therapy never performed it. Multivariate Logistic regression identified several factors associated with SMBG adherence: female gender, higher education level, higher income, longer T2D duration and education about SMBG.
CONCLUSIONSSMBG adherence in our Chinese population with T2D was less frequent than that in developed countries. Several factors influence SMBG adherence: gender, education level, income, T2D duration, therapy regimen and exposure to education about SMBG.

BACKGROUNDInsulin injection therapy is one of the most effective treatments for type 2 diabetes mellitus (T2DM). Many people with T2DM in western countries resist starting insulin therapy; whether the same is true in China is unknown. This survey-based study assessed acceptance and rejection of insulin therapy among individuals with T2DM in China and self-reported reasons for these therapy choices. It also examined what methods may be useful for increasing the rate of insulin acceptance.
METHODSA multi-center, cross-sectional survey was conducted between April and July 2010 to a convenience sample of inpatients and outpatients at 50 medical centers across 29 administrative divisions in China. Data were collected on sociodemographic and T2DM characteristics, therapy regime, and attitudes toward insulin therapy.
RESULTSA total of 6 043 patients were surveyed, and 5 961 complete questionnaires (98.6%) were used in the analysis. Just over half the respondents (3 460, 58.0%) reported negative attitudes to insulin therapy, including 2 508 of the 4 469 patients (56.1%) whose physicians had recommended it to them. Of the patients counseled to use insulin, 800 (17.9%) were unwilling to start therapy and cited the following reasons: inconvenience (64.3%); concerns over addiction (24.6%); pain (14.3%); side effects (14.1%); and high cost (13.6%). Logistic regression suggested that respondents would be more willing to undertake insulin therapy if they had received diabetes education, had positive attitudes to the treatment, had higher glycosylated hemoglobin level, or had suffered diabetes for a longer period or with more complications.
CONCLUSIONSPatients with T2DM in China are often resistant to insulin therapy if they have been diagnosed with the disease for a relatively short time or if the disease has been relatively mild. Educating patients on the benefits of insulin therapy, not only at the initial diagnosis with T2DM but also when insulin therapy becomes necessary, will likely increase their willingness to undertake it.

Objective:To investigate the association of left and right ventricular diameters in normal early pregnancy and early middle pregnancy to the biological growth parameters of fetus, and to establish the reference and Z-score model for left and right ventricles.Methods:Two hundred and forty-six fetuses in normal early pregnancy (11-13 + 6 weeks) and early middle pregnancy (14-17 + 6 weeks) from February 2019 to May 2019 in Sir Run Run Shaw Hospital were examined by routine ultrasound. Non-cardiac fetal biometric parameters included crown-rump length (CRL), biparietal diameter (BPD) and femoral length (FL) and gestation age (GA) based on menstrual age were assessed. The left and right ventricular widths (LVW, RVW) and ventricular lengths (LVL, RVL) were measured at the end of diastolic period by obtaining the standard four chamber view of fetal echocardiography. The end-diastolic areas (LVA, RVA) as the products of the ventricular widths and lengths, the global spherical indexes (GSI) of left and right ventricles (LVSI, RVSI), the ratios of left and right ventricular widths (LVW/RVW), the length ratios (LVL/RVL) and the area ratios (LVA/RVA) of both ventricles were calculated.GA, BPD and FL were used as independent variables. The predicted cardiac parameters and its derivative parameters were used as dependent variables. The corresponding reference range was established. The correlation between each standard deviation (SD) and independent variables was analyzed, and the corresponding Z-scores of left and right ventricular diameters were calculated by using the formula. Results:①LVW, RVW, LVL, RVL were found positively correlated with the increase of GA, BPD and FL, and the correlation between GA and LVW, RVW was the highest ( r=0.928, 0.930; all P<0.000 1). ②There was a positive correlation between LVA, RVA and GA ( r=0.868, 0.872; all P<0.000 1). LVSI, RVSI were found negatively correlated with GA ( r=-0.844, -0.861; all P<0.000 1), and LVSI>RVSI. LVW/RVW<1 and almost close to 1, the ratios decreased with the increase of GA( r=0.147, P<0.000 1). LVL/RVL>1, the ratios increased with the increase of GA( r=0.313, P<0.000 1). LVA/RVA>1, but there was no correlation with GA. ③The SD values of LVW, RVW, LVL, RVL positively correlated with independent variables. Taking GA and LVW as an example, the linear regression equation of LVW was Y=-5.338+ 0.549GA ( r=0.928, P<0.000 1), and the linear regression equation of LVW-SD was Y=-0.322+ 0.037GA( r=0.131, P<0.000 1). The Z-scores of LVW, RVW, LVL, RVL, LVA, RVA did not change with the changes of GA, BPD, and FL. Conclusions:The normal reference range and Z-scores of left and right ventricular lengths and widths can be simply and reliably established using statistical analysis, and these parameters might have potentials for more accurately and more early evaluating the normal development of fetal heart.
