Objective: To evaluate the effects of a home-school collaborative intervention on improving sugar sweetened beverages (SSBs) consumption behaviors among primary school students in grades 3 to 5 in Chengdu, so as to provide evidence for SSBs prevention and control strategies among primary school students. Methods: Using a stratified cluster random sampling method, a total of 2 006 students in grades 3 to 5 from 4 primary schools in Chengdu were enrolled from October to December 2024, including an intervention group ( n =769) and a control group ( n =1 237). The control group received routine psychological counseling, while the intervention group received a comprehensive home-school collaborative intervention integrating time perspective cultivation and family functioning improvement. A two level linear mixed effects model was used to analyze the net intervention effect, and the EBICglasso algorithm was used to construct variable association networks to identify core intervention targets. Results: After adjusting for confounders and clustering effects, the intervention significantly reduced the weekly frequency of SSBs consumption (decreased from baseline by 1.29 in the intervention group, 95% CI =-1.84 to -0.73; by 0.84 in the control group, 95% CI =-1.21 to -0.46; interaction P =0.01, Cohen s d=-0.16), improved SSBs consumption behavioral intention (decreased from baseline by 0.62 in the intervention group, 95% CI =-1.26 to -0.02; by 0.14 in the control group, 95% CI =-0.57 to 0.29; interaction P =0.02, Cohen s d =-0.15) and increased family functioning level (increased from baseline by 0.34 in the intervention group, 95% CI =-0.16 to 0.85; decreased by 0.08 in the control group, 95% CI =-0.42 to 0.25; interaction P =0.01, Cohen s d =0.17). A permutation test with 1 000 iterations showed no statistically significant difference in global network strength between the two groups ( P =0.19), whereas the differences in overall network structure and maximum edge weight were both statistically significant (all P <0.05), with present hedonistic time perspective, SSBs consumption attitude and behavioral intention identified as the core intervention targets. Conclusion The comprehensive home-school collaborative intervention effectively reduces SSB consumption frequency among primary school students and improves behavioral intention and family functioning.

Objective To investigate the longitudinal relationship between sleep duration(SD)and positive youth development(PYD)among primary and secondary school students in Chengdu city using a cross-lagged model,and to provide scientific evidence for enhancing sleep management practices for students.Methods A total of 4061 students of grades 3 through 9 from the Chengdu Child Positive Development Cohort were included in this three-wave longitudinal study.There was a one-year interval between one survey and the following round of survey,and the time points for the baseline,12-month follow-up,and 24-month follow-up surveys were designated T0,T1,and T2.The PYD of the participants was assessed using the Chinese version of the Positive Youth Development Scale.The demographic data and the average daily SD over the past month were collected.Spearman correlation analysis was performed to examine the associations between SD and PYD,and a cross-lagged model was used to investigate the longitudinal relationship between them.Results The average daily SD for the 3 rounds of surveys conducted at T0,T1,and T2 was 9.00(8.04,10.00)hours,10.44(9.67,11.11)hours,and 10.39(9.83,11.00)hours,respectively,while the PYD scores were 5.30(4.73,5.71),5.27(4.73,5.73),and 5.39(4.89,5.77),respectively.Statistical significance was found in the differences of SD and PYD scores across the 3 rounds(P＜0.05).Spearman correlation analysis revealed synchronous correlations between SD and PYD at all three time points(r=0.10 at T0,r=0.18 at T1,and r=0.21 at T2,P＜0.05)and significant lagged correlations(e.g.,r=0.10 for T1-PYD and T2-SD,and likewise,significant correlation was found for the 3 other cross-lagged paths).The cross-lagged model demonstrated that PYD at T0 and T1 positively predicted SD at T1 and T2,respectively(β0-1=0.116[95％CI,0.083-0.150],β1-2=0.097(95％CI,0.067-0.127),P＜0.05),and that SD at T0 and T1 also positively predicted PYD at T1 and T2(β0-1=0.028[95％CI,0-0.056],β1-2=0.042[95％CI,0.010-0.074],P＜0.05).According to these findings,a bidirectional predictive relationship between SD and PYD across different time points was observed in primary and secondary school students.Furthermore,PYD demonstrated better performance for predicting SD than SD did for PYD.Subgroup analysis by sex confirmed the robustness of the predictive power of PYD for SD.Conclusion This study reveals a positive bidirectional predictive relationship between SD and PYD among primary and secondary school students,suggesting that higher levels of PYD may contribute to adequate sleep.These findings provide critical scientific evidence for schools and families to strengthen sleep management and promote the holistic development and well-being of adolescents.

The precise and rapid monitoring of multiple organ dysfunction is crucial in drug discovery. Traditional methods, such as pathological analysis, are often time-consuming and inefficient. Here, we developed a multiplexed near-infrared window two (NIR-II) fluorescent bioimaging method that allows for real-time, rapid, and quantitative assessment of multiple organ dysfunctions. Given that existing probes did not fully meet requirements, we synthesized a range of NIR-II hemicyanine dyes (HDs) with varying absorption and emission wavelengths. By modifying these dyes, we achieved high spatial and temporal resolution imaging of the liver, kidneys, stomach, and intestines. This method was further applied to investigate disorders induced by cisplatin, a drug known to cause gastric emptying issues along with liver and kidney injuries. By monitoring the metabolic rate of the dyes in these organs, we accurately quantified multi-organ dysfunction, which was also confirmed by gold-standard pathological analysis. Additionally, we evaluated the effects of five aristolochic acids (AAs) on multiple organ dysfunction. For the first time, we identified that AA-I and AA-II could cause gastric emptying disorders, which was further validated through transcriptomics analysis. Our study introduces a novel approach for the simultaneous monitoring of multi-organ dysfunction, which may significantly enhance the evaluation of drug side effects.

Objective To evaluate the significant clinical value of an intelligent dispatching platform based on the 120 command system and provide the basis for improving emergency service efficiency. Methods Convenience sampling was used to choose 356 patients who received pre-hospital care in the Jiaxing Emergency Center from August 2023 to May 2024 as research objects. The 178 patients who made phone calls to the 120 center from August to December 2023 (namely before the establishment of intelligent dispatching platform) served as a control group,while another 178 cases who made phone calls to the 120 center from January to May 2024 (namely after the establishment of intelligent dispatching platform) served as an observation group. The optimal ambulance was chosen and sent to receive the patients by the dispatcher himself in the control group,while the intelligent dispatching platform designed by the research team and computer engineers was used in the observation group. The platform was made up of multimodal receipt of alarms,accurate location of phone call places,matching and dispatching of ambulance resources,and collaborative management functions within the region. At the same time,geographic information,hospital information,and emergency vehicle information were completed to achieve united dispatching and whole-process quality control all over the region. The emergency response time,2 minutes ambulance dispatching rate,coincidence rate of medical treatment principles,and success rate of cardiopulmonary resuscitation in cities and rural areas were compared between the control group (before the establishment of intelligent dispatching platform) and the observation group (after the establishment of intelligent dispatching platform). Results The emergency response time in the observation group after the establishment of intelligent dispatching platform was shorter than that in the control group in cities (minutes:8.64±0.99 vs. 10.57±1.00,P<0.05),while there was no statistical significance between the observation group and the control group in rural areas (minutes:11.66±1.49 vs. 11.94±1.70,P>0.05). The 2 minutes ambulance dispatching rate higher than those in the control group[99.44％ (177/178) vs. 98.31％ (175/178)],there was no statistical significance (P>0.05),the coincidence rate of medical treatment principles in the observation group were significantly higher than those in the control group[98.88％ (176/178) vs. 89.89％ (160/178),P<0.05],For the observation group,the success rate of cardiopulmonary resuscitation in the observation group was slightly higher than that in the control group[18.92％ (7/37) vs. 13.51％ (5/37)],but there was no statistical significance (P>0.05). Conclusion The construction of an intelligent dispatching platform with the function of united dispatching,collaborative management of resources,and whole-process quality control all over the region can improve emergency service efficiency and effectiveness,thus promoting the development of pre-hospital care course.
