Objective To observe the clinical effect , blood glucose time , clearance time of ketone body , correction time of acidosis and influence on average daily dosage of insulin of supplementing Qi and nourishing Yin combined with insulin treatment of patients with diabetic ketoacidosis (DKA).Methods 67 cases of DKA were divided into 2 groups.Control group (n=32) was giv-en micro injection of pump continuous infusion of insulin and aggressive fluid resuscitation for potassium supplement , water and elec-trolyte maintaining and acid -base balance;the observation group ( n=35 ) was given oral Chinese medicine for supplementing Qi and nourishing Yin on the basis of control group .The clinical effect after treatment , blood glucose time , clearance time of ketone body, correction time of acidosis , average daily dosage of insulin and the average number of hypoglycemia per capita were compared and analyzed .Results Blood sugar could be controlled faster in observation group .Clearance time of urine ketone and correction time of acidosis were significantly shortened .The dosage of insulin and number of hypoglycemia per capita were greatly reduced .There were significant differences compared with the control group (p<0.01);in terms of clinical effect, 19 cases of observation group were markedly effective , 14 cases effective , and 2 cases ineffective with the efficiency rate of 94.29%; 13 cases of control group were markedly effective , 10 cases effective , and 9 cases ineffective with the efficiency rate of 71.88%.There were differences between the two groups (p<0.05).Conclusion Supplementing Qi and nourishing Yin can significantly improve the curative effect in the treat -ment of DKA .

Objective: To analyze the duration and influencing factors of moderate and vigorous physical activity(MVPA) on weekends for primary school students in grades 4 to 6 in Beijing, and to provide a reference for formulating health education and promotion measures. Methods: Multi stage stratified cluster sampling method was used to randomly select 2 515 students from grades 4-6 in 14 primary schools in Beijing, and a self administered questionnaire was used to record MVPA on weekend, social demographic characteristics, other related health behaviors and knowledge. Multivariate Logistic regression analysis was used to explore the influencing factors of MVPA on weekends. Results: The prevalence of insufficient MVPA on weekends in Beijing was 63.54 %, and the prevalence was higher among girls (69.92%) than boys (57.81%) ( χ 2=39.65, P <0.01). Multiple Logistic regression analysis revealed that girls ( OR =1.74), living in rural areas ( OR =1.41), participants attending general schools ( OR = 1.34 ), from divorced family ( OR =1.46), and short sleep duration ( OR =1.50) were more likely to fail to meet the MVPA recommendations( P <0.05). Conclusion It is quite common that no sufficient weekend MVPA among senior primary school students, among them, the outer suburbs and schools with relatively weak teaching resources are the key places that need attention, and girls are the key groups that need attention.

Objective: To explore the prevalence and associated factors of non learning-based screen time of 4-6 grade school students in Beijing, and to provide a basic data for further research on hazard control measures such as myopia, overweight and obesity among children and adolescents in Beijing. Methods: Multistage stratified random cluster sampling method was adopted. A total of 2 515 primary school students were randomly selected in from schools in Beijing, self-developed questionnaire was used to investigate on the time for each electronic products usage for non-learning purpose, the total of electronic products usage every day and other information. Results: The rates of screen time >15 minutes each time and ≥1 h daily were 48.43%, 22.90%, respectively. Multiple Logistic regression analysis showed that ordinary school, 6 th grade, male, single-parent family and other types of family, and lack of moderate-to-vigorous physical activity at weekend were associated with the students’ non learning-based screen time (OR=1.66, 2.28, 1.27, 1.44, 1.87, 2.20, P<0.05). Conclusion The situation of excessive screen time of primary school students was improved in Beijing, but still be prevelent, male students of grade 4 should be given more attention, and more importance should be attached to the offect of family in children.
