Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Numerous c-mesenchymal-epithelial transition (c-MET) inhibitors have been reported as potential anticancer agents. However, most fail to enter clinical trials owing to poor efficacy or drug resistance. To date, the scaffold-based chemical space of small-molecule c-MET inhibitors has not been analyzed. In this study, we constructed the largest c-MET dataset, which included 2,278 molecules with different structures, by inhibiting the half maximal inhibitory concentration (IC₅₀) of kinase activity. No significant differences in drug-like properties were observed between active molecules (1,228) and inactive molecules (1,050), including chemical space coverage, physicochemical properties, and absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles. The higher chemical diversity of the active molecules was downscaled using t-distributed stochastic neighbor embedding (t-SNE) high-dimensional data. Further clustering and chemical space networks (CSNs) analyses revealed commonly used scaffolds for c-MET inhibitors, such as M5, M7, and M8. Activity cliffs and structural alerts were used to reveal "dead ends" and "safe bets" for c-MET, as well as dominant structural fragments consisting of pyridazinones, triazoles, and pyrazines. Finally, the decision tree model precisely indicated the key structural features required to constitute active c-MET inhibitor molecules, including at least three aromatic heterocycles, five aromatic nitrogen atoms, and eight nitrogen-oxygen atoms. Overall, our analyses revealed potential structure-activity relationship (SAR) patterns for c-MET inhibitors, which can inform the screening of new compounds and guide future optimization efforts.

Objective To explore and analyze the characteristics and transmission routes of carbapenem-resistant Klebsiella pneumoniae(CRKP)strains in intensive care unit(ICU).Methods From January to October 2023,17 clinical infection isolates(clinical infection group),5 active screening isolates(active screening group),and 7 envi-ronmental isolates(environmental group)of CRKP in the liver surgery ICU of a hospital were selected and analyzed by whole-genome sequencing.The differences in resistance genes,virulence genes,and sequence typing(ST)were compared,and transmission routes were analyzed based on the phylogenetic tree.Results 29 strains of CRKP car-ried 4-18 resistance genes and 52-98 virulence genes,respectively.There were no statistically significant diffe-rences in genotype distribution of resistance genes,the number of virulence genes,and gene types among three groups of CRKP(all P＞0.05).ST showed that 29 CRKP strains mainly consisted of two categories:ST11 and ST15.Based on the phylogenetic tree constructed from the core genome,there were 7 highly homologous groups of CRKP,among which 4 groups had clear epidemiological associations.Conclusion CRKP in ICU carries more re-sistance and virulence genes,and some strains are highly homologous in ST and phylogenetic tree,which may lead to cross transmission.In the future,prevention and control measures should be strengthened to reduce the trans-mission of CRKP.

Objective:To investigate the characteristics of visual and auditory sustained attention and sex differences in pupils of different grades.Method:Totally 231 students from grades 1 to 6 participated in this stud-y.The development and sex differences of sustained attention were measured by average reaction times,coefficients of variation for reaction times,omission error rates and commission error rates in visual and auditory two-choice re-action time(CRT)tasks.Result:The students in grade 5 had significantly slower visual average reaction times and coefficients of variation for reaction times(P＜0.001 or P＜0.05)than those in grade 3.The students in grade 5 had significantly lower auditory average reaction times,coefficients of variation for reaction times,omission error rates and commission error rates(P＜0.001 or P＜0.01)than those in grade 1.There was no significant sex differ-ences in visual or auditory average reaction times,coefficients of variation for reaction times or omission error rates(Ps＞0.05).Conclusion:There would be age differences in characteristics of both visual and auditory sustained at-tention in pupils,and may be no sex difference in visual or auditory sustained attention.

Objective To investigate the cerebellar hemisphere homotopic functional connectivity in patients with concomitant exotropia(CE)based on voxel-mirrored homotopic connectivity(VMHC),aiming to provide a reference basis for the neuropathogenesis of CE.Methods A total of 36 CE patients who visited the Ophthalmology Department of Jian-gxi Provincial People's Hospital from October 2021 to October 2022 were included as the study group(CE group),while healthy volunteers who were recruited from society and matched in age and gender with the CE group were included as the control group(HC group).Subjects in both groups underwent 3.0T functional magnetic resonance imaging scans,and the magnetic resonance data were processed using DPABI_V4.0 software and SPM8 to compare the differences in VMHC values of various brain regions of subjects in the two groups.Results Compared with the HC group,the VMHC values in the cerebellar regions 6,8 and 9 on both sides and vermis cerebelli region 2 of subjects in the CE group were significantly re-duced(all P＜0.05).The difference pattern of VMHC values in cerebellar regions showed that compared with the HC group,the VMHC values in cerebellar regions 6,8,9 and vermis cerebelli region 2 of subjects in the CE group were signifi-cantly different,especially the VMHC value in cerebellar region 9.Conclusion Functional changes in the cerebellar hemisphere,especially in cerebellar hemisphere region 9,play an important role in the pathogenesis of CE,which may be closely related to eye position voxel control and fusion.

Objective:To construct an interactive health care participation program for patients undergoing lower limb bone transport based on the interactive patient participation safety theory framework and the Patient Health Engagement model.Methods:From August to November 2022, through literature review and interviews with patients undergoing lower limb bone transport, a preliminary draft of the interactive health care participation program was developed based on the interactive patient participation safety theory framework and the Patient Health Engagement model. The Delphi method was used to conduct two rounds of consultations with 25 experts to screen and revise the program items.Results:The expert positive coefficients for the two rounds of expert consultations were 92.00% (23/25) and 100.00% (23/23). The authority coefficient was 0.913, and the Kendall's W coefficients for consistency were 0.127 and 0.140 ( P<0.01). The final program included three primary items, 22 secondary items, and 65 tertiary items. Conclusions:The interactive health care participation program for patients undergoing lower limb bone transport constructed in this study is both scientific and practical, can provide a theoretical basis and practical guidance for patient engagement in health care.
