Abstract The framework of pediatric inactivity triad (PIT) consists of three core factors:exercise deficit disorder, pediatric dynapenia, and physical illiteracy. It emphasizes that physical activity (PA) insufficiency is not a singular phenomenon but rather a vicious cycle resulting from the interaction of multiple factors. Based on the PIT framework, the paper explores its core components and their interrelationships, as well as analyzes the framework s application value and practical implications for improving PA levels among Chinese children and adolescents,to provide a systematic theoretical perspective for analyzing the complex causes of PA insufficiency in children and adolescents, and to offer a scientific basis for developing intervention strategies.

Liraglutide (Lira), a glucagon-like peptide-1 (GLP-1) receptor agonist approved for diabetes and obesity, has shown significant potential in treating metabolic dysfunction-associated steatotic liver disease (MASLD). However, its systematic molecular regulation and mechanisms remain underexplored. In this study, a mouse model of MASLD was developed using a high-fat diet (HFD), followed by Lira administration. Proteomics and glycoproteomics were analyzed using label-free liquid chromatography-tandem mass spectrometry (LC-MS/MS), while potential molecular target analysis was conducted via quantitative real-time polymerase chain reaction (qPCR) and Western blotting. Our results revealed that Lira treatment significantly reduced liver weight and serum markers, including alanine aminotransferase (ALT) and others, with glycosylation changes playing a more significant role than overall protein expression. The glycoproteome identified 255 independent glycosylation sites, emphasizing the impact of Lira on amino acid, carbohydrate metabolism, and ferroptosis. Simultaneously, proteomic analysis highlighted its effects on lipid metabolism and fibrosis pathways. 21 signature molecules, including 7 proteins and 14 N-glycosylation sites (N-glycosites), were identified as potential targets. A Lira hydrogel formulation (Lira@fibrin (Fib) Gel) was developed to extend drug dosing intervals, offering enhanced therapeutic efficacy in managing chronic metabolic diseases. Our study demonstrated the importance of glycosylation regulation in the therapeutic effects of Lira on MASLD, identifying potential molecular targets and advancing its clinical application for MASLD treatment.

Objective To investigate the expression and prognostic value of uncoupling protein 2(UCP2)and ubiquitin associated protein 2-like(UBAP2L)in non-small cell lung cancer(NSCLC).Methods A total of 94 patients with NSCLC who received surgical treatment in a hospital from March 2019 to March 2021 were selected as the study objects.The expressions of UCP2 protein,UBAP2L protein,UCP2 mRNA and UBAP2L mRNA in cancer tissues and adjacent tissues of NSCLC patients were detected by real-time fluorescence quan-titative polymerase chain reaction and immunohistochemistry.The correlation between UCP2 mRNA and UBAP2L mRNA in NSCLC was analyzed by Pearson correlation.Kaplan-Meier curve was used to analyze the differences in survival rates of NSCLC patients with different UCP2 mRNA and UBAP2L mRNA expres-sions,and multivariate Cox regression was used to analyze the prognostic factors of NSCLC patients.Results The positive rate of UCP2 protein and UBAP2L protein in cancer tissues of NSCLC patients was higher than that in adjacent tissues,and the difference was statistically significant(P＜0.05).The expressions of UCP2 mRNA and UBAP2L mRNA in cancer tissues of NSCLC patients were significantly higher than those in adjacent tissues,and the differences were statistically significant(P＜0.05).There was a positive cor-relation between UCP2 mRNA and UBAP2L mRNA expression in NSCLC patients(r=0.721,P＜0.001).The expression of UCP2 mRNA and UBAP2L mRNA in cancer tissues of NSCLC patients was related to TNM stage and lymph node metastasis.There was significant difference in 3-year survival rate between UCP2 mRNA high expression group and UCP2 mRNA low expression group(P＜0.05).There was significant difference in 3-year survival rate between UBAP2L mRNA high expression group and UBAP2L mRNA low expression group(P＜0.05).TNM stage Ⅲ A,lymph node metastasis,UCP2 mRNA high expression and UBAP2L mRNA high expression were risk factors for prognosis of NSCLC patients(P＜0.05).Conclusion UCP2 protein,UBAP2L protein,UCP2 mRNA and UBAP2L mRNA are up-regulated in NSCLC patients,and UCP2 mRNA and UBAP2L mRNA are helpful to evaluate the survival prognosis of NSCLC patients.

Objective: To examine the developmental trajectory of fine motor ability in schoolage children with attention deficit hyperactivity disorder (ADHD) for two years, so as to provide scientific evidence to promote motor development in ADHD children. Methods: From April to June 2019, 31 children aged 6-8 years old were selected from a public elementary school. They were diagnosed with ADHD by two psychiatric professionals according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Additionally, 31 typical developmental children, matched for age, sex and IQ with the ADHD group, were recruited as the control group. Fine motor ability was assessed with tasks of hand manual dexterity in Movement Assessment Battery for Children-2 (MACB-2), and a followup assessment was conducted from April to June 2021. The development changes of fine motor ability between two groups of children were compared by using t test and repeated measures analysis of variance. Results: Between baseline and followup periods after two years, the total score of hand fine motor in the ADHD group did not show significant improvement (7.4±3.0, 8.0±3.4; t=-1.05, P>0.05), while there was a small effect size improvement in typically developing control group (9.5±2.1, 10.5±2.4; t=-2.12, effect size=0.38, P<0.05). Followup after two years, coin/peg throwing scores with dominant hand improved between ADHD group and control group (7.0±3.3, 9.5±3.2; 8.4±2.8, 11.6±1.6) (t=-3.74, -6.33, P<0.01; effect size=0.67, 1.14), with a smaller improvement in the ADHD group. The score for threading beads/threads decreased in between ADHD group and control group (7.9±2.4, 5.8±3.1; 9.2±1.1, 8.2±1.9) (t=3.89, 2.78, P<0.01; effect size=0.70, 0.50), with a greater decrease in the ADHD group. Conclusions The development speed of fine motor ability in children with ADHD aged 6-8 is slow and continues to lag behind normal developmental children. Fine motor development in children with ADHD should be closely monitored, and targeted interventions should be implemented when necessary.

ObjectiveTo provide a basis for human enteroviruses prevention and control by monitoring the enterovirus （EV） and its main virus types. MethodsSamples of hand-foot-and-mouth disease， herpetic angina and fever clinic patients in Dapeng New District of Shenzhen from 2016 to 2022 were tested for EV with real-time polymerase chain reaction （PCR）. To identify the isolates of EV， VP1 genes of EV were amplified with nested reverse transcription PCR， and then sequenced.A geneticphylogenetic tree was constructed based on the VP1 gene. ResultsAmong the 1 124 suspected hand-foot-and-mouth disease cases， 740 （65.84%） tested EV positive. Coxsackievirus A6 （CVA6） and Coxsackievirus A16 （CVA16） were the main two serotypes with regular cycle trends. Of the 137 suspected herpetic angina cases， 88 （64.23%） were EV positive， with Coxsackievirus A4 （CVA4） and CVA16 as the dominant serotypes. Among 428 respiratory infection specimens， 71 （16.59%） were EV positive. Coxsackievirus A4 （CVA4） was the predominant serotype which caused herpetic angina and respiratory infection. The epidemic EV isolates CVA6 from Shenzhen had a close genetic relationship with isolates in China’s mainland. ConclusionThe main serotypes EV CVA6 and CVA16 which caused hand-foot-and-mouth disease exhibit cyclical trends . The risk of EV transmitted from abroad is low， but their genetic variation and virulence change should be monitored continuously. In addition， the monitoring of dominant isolates CVA4 which cause herpetic angina and respiratory infection should be strengthened.

Objective:To evaluate and screen the regimens of tigecycline intraventricular injection in extensively drug resistant Acinetobacter baumannii (XDRAB) intracranial infection based on Monte Carlo simulation and pharmacokinetic/pharmacodynamic (PK/PD) model.Methods:Nine patients with XDRAB intracranial infection confirmed as having susceptibility to tigecycline or polymyxin antimicrobials from January 1, 2018 to December 31, 2023 were screened from electronic medical record system in Second Affiliated Hospital of Shandong First Medical University. WHONET software was used to extract pathogen susceptibility data isolated from cerebrospinal fluid samples. Minimum inhibitory concentration (MIC) of tigecycline against XDRAB was analyzed by drug susceptibility test; different regimens for intraventricular tigecycline injection were designed based on MIC: 2 mg/12 h, 3 mg/12 h, 4 mg/12 h, 5 mg/12 h, 6 mg/12 h, and 10 mg/12 h, with drug concentration of 0.5 mg/mL or 1.0 mg/mL once a day. Target value of PK/PD index was set as ?C max/MIC≥8; Monte Carlo was used to simulate the compliance of PK/PD index of tigecycline with different MIC against XDRAB for different dosed regimens (probability of target attainment [PTA] and cumulative fraction of response [CFR]); the best regiment was selected (screening basis: PTA≥90% or CFR≥90%). Results:(1) A total of 27 strains of pathogenic bacteria from 9 patients were extracted from drug susceptibility test, in which MIC of tigecycline against XDRAB was 55.56% for 2 mg/L, 25.93% for 4 mg/L, and 18.52% for 8 mg/L. (2) When the drug concentration was 0.5 mg/mL or 1.0 mg/mL, respectively, all 6 regimens had PTA>90% at 2 mg/L MIC; 5 regimens, except for 2 mg/12 h, had PTA>90% at 4 mg/L MIC; regimens of 5 mg/12 h, 6 mg/12 h, and 10 mg/12 h could achieve PTA>90% at 8 mg/L MIC. (3) When the drug concentration was 0.5 mg/mL, regimens of 4 mg/12 h, 5 mg/12 h, 6 mg/12 h, and 10 mg/12 h could achieve CFR>90%; when the drug concentration was 1 mg/mL, regimens of 4 mg/12 h, 5 mg/12 h, 6 mg/12 h, and 10 mg/12 h could achieve CFR>92%.Conclusion:In intraventricular tigecycline injection for XDRAB intracranial infection, 2 mg/12 h regimen is available in 2 mg/L MIC, 3 mg/12 h regimen is available in 4 mg/L MIC, and 5 mg/12 h regimen is available in 8 mg/L MIC, with either 0.5 mg/mL or 1 mg/mL concentration.

Objective:To observe the effects of warming needle therapy combined with the modified Hua Tan Tong Luo Tang(decoction for dissipating phlegm and unblocking collaterals)on post-stroke cognitive impairment due to obstruction of wind-phlegm. Methods:A total of 78 patients who met the inclusion criteria were randomly assigned to an observation group and a control group,with 39 patients in each group.Both groups received conventional treatment.The control group was additionally treated with the modified Hua Tan Tong Luo Tang,while the observation group received warming needle therapy in addition to the treatment given to the control group.Scores on the mini-mental state examination(MMSE),Montreal cognitive assessment(MoCA),and activities of daily living(ADL)were assessed before and after treatment.Adverse reactions and clinical efficacy were analyzed and compared between the two groups after treatment. Results:The total effective rate was 82.1%in the observation group and 61.5%in the control group,showing statistical significance between the two groups(P<0.05).After treatment,the MMSE,MoCA,and ADL scores of both groups were significantly higher than those before treatment within each group(P<0.05).Notably,the scores in the observation group were higher than those in the control group(P<0.05).No adverse reactions occurred in either group during the treatment period. Conclusion:Based on the conventional treatment,compared to modified Hua Tan Tong Luo Tang alone,warming needle therapy combined with the modified Hua Tan Tong Luo Tang showed superior clinical efficacy in treating post-stroke cognitive impairment due to obstruction of wind-phlegm,and this combined therapy also showed high safety.

The tumor microenvironment,particularly the hypoxic property and glutathione(GSH)overexpression,substantially inhibits the efficacy of cancer therapy.In this article,we present the design of a magnetic nanoplatform(MNPT)comprised of a photosensitizer(Ce6)and an iron oxide(Fe3O4)/manganese oxide(MnO2)composite nanozyme.Reactive oxygen species(ROS),such as singlet oxygen(1O2)radicals produced by light irradiation and hydroxyl radicals(·OH)produced by catalysis,are therapeutic species.These therapeutic substances stimulate cell apoptosis by increasing oxidative stress.This apoptosis then triggers the immunological response,which combines photodynamic therapy and T-cell-mediated immunotherapy to treat cancer.Furthermore,MNPT can be utilized as a contrast agent in magnetic resonance and fluorescence dual-modality imaging to give real-time tracking and feedback on treatment.

Objective The occurrence of chickenpox in rapidly developing areas poses substantial seasonal risk to children.However,certain factors influencing local chickenpox outbreaks have not been studied.Here,we examined the relationship between spatial clustering,heterogeneity of chickenpox outbreaks,and socioeconomic factors in Southern China. Methods We assessed chickenpox outbreak data from Southern China between 2006 and 2021,comprising both relatively fast-growing parts and slower sub-regions,and provides a representative sample of many developing regions.We analyzed the spatial clustering attributes associated with chickenpox outbreaks using Moran's I and local indicators of spatial association and quantified their socioeconomic determinants using Geodetector q statistics. Results There were significant spatial heterogeneity in the risk of chickenpox outbreaks,with strong correlations between chickenpox risk and various factors,particularly demographics and living environment.Furthermore,interactive effects among specific are factors,such as population density and per capita residential building area,percentage of households with toilets,percentage of rental housing,exhibited q statistics of 0.28,0.25,and 0.24,respectively. Conclusion This study provides valuable insights into the spatial dynamics of chickenpox outbreaks in rapidly developing regions,revealing the socioeconomic factors affecting disease transmission.These implications extend the formulation of effective public health strategies and interventions to prevent and control chickenpox outbreaks in similar global contexts.
