Objective:To study the association of RAC1 gene polymorphisms with protein expression levels of Rac1-GTP. Methods:A total of 182 healthy Hans population in Hubei were recruited. The 4 tag-SNPs in RAC1 gene were genotyped by Real time TaqMan-MGB genotyping assay. And the Rac1-GTP protein levels in plasma samples from all participants were determined by enzyme linked immunosorbent assays ( ELISA ) . The distribution characteristics of Rac1-GTP expression levels were also analyzed. Furthermore,the expression levels of Rac1-GTP were compared among different genotypes of the 4 tag-SNPs in RAC1 gene. Results:The distribution of Rac1-GTP expression levels was positive skewed in healthy Chinese Hans population. The expression levels were significantly higher in females than in males (P<0. 05),and appeared in decreased trend with age,but without significant differences (P>0. 05). Different expression levels of Rac1-GTP were observed in different genotypes for rs702482 and rs10951982 (P<0. 05). However,no significant difference was found for rs702483 and rs6954996 (P>0. 05). Conclusion:RAC1 genetic polymorphisms can potentially affect the expression levels of Rac1-GTP protein in healthy Chinese Hans population.

Objective: To establish a risk assessment index system for epidemic infectious diseases in primary and secondary schools, for early warning and prevention of school infectious diseases accurately and timely. Methods: Through literature review, the indicators pool was established by consulting relevant experts and referring to practical experience. Then two rounds of expert consultation using the Delphi method were conducted(13 experts of round 1, and 20 experts of round 2). The concentration of expert opinions (the average, the percentage of full marks) and the coordination of expert opinions (the coefficient of variation, the coordination coefficient W ) were calculated and analyzed. The coordination coefficient W was obtained by nonparametric Kendall s W test of multiple samples. According to the experts feedback, necessary addition, reduction and modification of the indicators were carried out to determine the evaluation index system, and the analytic hierarchy process (AHP) was used to calculate the weight of each indicator. Results: The expert authority coefficients of the two rounds of consultation were 0.89 and 0.88, respectively, and the form recovery rate was 100%. The range of the variation coefficient of each three level indicator was 0.07-0.31 and 0.06-0.19, and the coordination coefficient W was 0.25 and 0.47, respectively, indicating that the consistency and credibility of expert opinions were good. Finally, the risk assessment index system of infectious diseases in primary and secondary schools was established, which was composed of 5 first level indexes, 23 second level indexes and 86 third level indexes. The AHP was used to calculate the intra level weight of the index. The variation coefficient of five first level indicators of school health management and security system, school health personnel facilities, health monitoring and cognition level, severity and coping measures were 0.09, 0.06, 0.08, 0.12 and 0.06 , respectively, and the weight coefficients were 20.42%, 21.19%, 19.87%, 17.45% and 21.08%, respectively. Conclusion The risk assessment index system of school infectious diseases is applicable to primary and secondary schools. The initiative, coordination and authority of experts in this system are all high. It is of practical guiding significance for the early warning of infectious diseases in primary and secondary schools.

Objective: To investigate incidence of traffic injury and its associated factors among secondary school students in Shanghai, so as to provide scientific basis for intervention. Methods: Using the method of multi stage stratified random cluster sampling, an on-the-spot anonymous questionnaire survey was conducted among 19 629 adolescents from 16 districts in Shanghai from May to June 2021. The multivariate Logistic regression was used to analyze possible associated factors. Results: The rate of road traffic injuries among secondary school students in Shanghai was 0.74%, the highest reporting rate among secondary vocational school students (1.35%), followed by junior high school students (0.72%), and the lowest reporting rate of road traffic injuries among senior high school students (0.55%), with statistically significant differences ( χ 2=13.39, P <0.01). The results of multivariate Logistic regression analysis showed that the junior high school ( OR =0.56, 95% CI =0.35-0.89) or senior high school ( OR = 0.40 , 95% CI =0.24-0.68) and residential school ( OR =0.39, 95% CI =0.18-0.88) were protective factors of road traffic injuries( P <0.05). Male ( OR =1.65, 95% CI =1.14-2.37), unaware of seat belt ( OR =6.38, 95% CI =2.81-14.50), had a cycling chase/fight ( OR =2.33, 95% CI =1.39-3.90), music or phone calls on a bicycle ( OR =2.54, 95% CI =1.72-3.75) were positively correlated with road traffic injury( P <0.05). Conclusions The road traffic injury among secondary school students in Shanghai is related to many factors, and traffic hazards are common among students in all school sections. Targeted measures should be taken to strengthen traffic safety knowledge education and intervention in healthy behaviors among adolescents, in order to reduce the incidence of road traffic injury.

Objective: To understand the relationships of social exclusion, personality trait and emotion regulation with willingness to seek help after being bullied, and to provide reference for rationalized intervention of campus bullying among middle school students. Methods: A tatal of 2 040 middle school students from a middle school in Jiangxi Province were selected as the research objects, and surveyed by general situation questionnaire, Olweus Bullying Questionnaire, Willingness to Seek Help Scale, social exclusion scale, personality scale and Emotion Regulation Scale. Among them, a further survey of 381 bullies was conducted and SPSS 26.0 was used for statistical processing of data. Results: About 55.88% (133/238) and 58.74% (84/143) reported willingness to seek help after being bullied among middle and high school students, respectively( χ 2=0.30, P >0.05). There were no significant differences in gender and residency( P >0.05). In junior middle school students, compared with the non help willingness group( 3.83± 0.78，3.35±1.03，3.33±1.03，29.81±7.77), the rejected scores of the help willingness group were lower(3.57±0.75), scores of affinity and openness in personality traits were higher(3.69±0.88，3.72±0.79), the cognitive reappraisal scores were higher( 32.42 ±8.25). Among senior middle school students, the rejected and expression suppression scores of the help willingness group were lower(3.51±0.67，26.96±7.47), while extroversion personality traits were higher(3.61±0.95). Multivariate unconditional Log binomial regression analysis showed that high score of expression suppression was associated with less willingness to seek help( OR=0.94, P =0.02). Conclusion Social exclusion, personality trait and emotional regulation may have certain influences on willingness to seek help after being bullied among junior and senior middle school students, effects varies by grade level.

Objective: To explore the association between dietary behaviors and sleep duration among middle school students in Shanghai, so as to provide reference for interventions targeting insufficient sleep. Methods: From May to June 2021, a stratified cluster random sampling method was employed to select a sample of 10-17yearold middle school students for monitoring their healthrisk behaviors. A total of 5 538 valid questionnaires were collected. The survey included items such as daily sleep duration, weekly consumption of sugary beverages, freshly squeezed fruit juice, fresh fruits, fresh vegetables, fried foods, milk and yogurt, breakfast habits, and frequency of eating outside. Statistical analysis was conducted using Chisquare test, Wilcoxon ranksum test, and multivariable Logistic regression model. Results: About 73.7% of middle school students reported insufficient sleep in Shanghai. There was a positive correlation between the average daily consumption of fresh fruits and breakfast consumption with sleep duration. In other words, a higher frequency of consuming fresh fruits (OR=1.29) and eating breakfast (OR=1.07) were associated with a higher likelihood of sufficient sleep. Conversely, there was a negative correlation between the frequency of consuming desserts (OR=0.78) and fried foods (OR=0.88) and sleep duration (P<0.05). Conclusions Increasing the consumption of fresh fruits and maintaining regular breakfast habits while reducing the intake of fried foods can contribute to achieving sufficient sleep among middle school students. When implementing interventions to improve sleep among middle school students, promoting healthy and balanced diets can be considered as one of the intervention strategies.

Objective: To elucidate the association between biorhythm disorders and health risk behaviors in adolescence, so as to provide reference for appropriate interventions. Methods: From March to April 2023, 2 381 adolescents in Shanghai were selected as research objects using convenience sampling and stratified random cluster sampling methods. The Self rating Questionnaire of Biological Rhythm Disorders for Adolescents (SQBRDA) and the self report health risk behaviors questionnaire were used to investigate the status of adolescent biorhythm disorders and nine kinds of health risk behaviors, while a multivariate Logistic regression model was employed to analyze the association between the two variables. Results: The average SQBRDA score was (68.25±0.42) The incidence and detection rates of health risk behaviors in the groups with no co occurrence, mild co occurrence, moderate co occurrence, and severe co occurrence were 234(9.83%), 1 176(49.39%), 830(34.86%) and 141(5.92%), respectively. The total SQBRDA score was positively correlated with the risk of co occurrence of health risk behaviors. The risk of mild co occurrence, moderate co occurrence, and severe co occurrence of health risk behaviors was 9.05 times (95% CI =4.25-19.15, P <0.01), 44.55 times (95% CI =20.75-96.05, P <0.01) and 110.05 times (95% CI =40.65-297.95, P <0.01) higher, respectively, among adolescents with higher scores of biorhythm disorders compared to adolescents with lower scores of biorhythm disorders. Conclusions Health risk behaviors among adolescents in Shanghai draw attention to a serious phenomenon whereby biorhythm disorders are positively correlated with the risk of co occurrence. Comprehensive interventions aimed at addressing adolescent health risk behaviors should focus on regulating biorhythm disorders.
