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.

Foot-and-mouth disease (FMD) is one of the major animal infectious diseases in the world. All cloven-hoofed animals are susceptible to FMD. Vaccination is still the first choice for the prevention and control of FMD. mRNA vaccines can be rapidly designed, synthesized, and produced on a large scale in vitro, and they can induce effective protective immune responses, demonstrating the advantages of rapid development, easy preparation, and low biosafety risks. The design of untranslated regions is a key to enhancing the expression and efficacy of mRNA vaccines. In order to generate an efficient FMD mRNA vaccine, we designed three FMD P12A3C expression vectors with different untranslated regions and synthesized corresponding mRNAs. By comparing expression efficiency of these vectors and their mRNAs at different time points and in different cell lines, we found that the mRNA P12A3C-UTR3 had the best expression and universality. This study laid a foundation for the development of mRNA vaccines against FMD and provided a theoretical basis for the optimal sequence design of efficient mRNA.

BackgroundRehabilitation for schizophrenia typically relies on pharmacological interventions， yet their efficacy in improving social function and quality of life remains limited. In recent years， non-pharmacological approaches have shown promise in enhancing rehabilitation outcomes. However， research on the effectiveness of psychomotor therapy specifically for young and middle-aged schizophrenic inpatients is limited. ObjectiveTo explore the effects of psychomotor therapy on the rehabilitation of young and middle-aged schizophrenic inpatients， and to provide a reference for treatment strategies. MethodsA total of 104 young and middle-aged schizophrenic inpatients who met the International Classification of Diseases，tenth edition （ICD-10） diagnostic criteria and hospitalized in the Fourth People's Hospital of Wuhu from June 2021 to June 2022 were selected. Patients were randomly divided into two groups of 52 each using random number table method. Both groups received treatment with risperidone tablets （2~4 mg/d） ， along with routine nursing care. Additionally， the research group received an extra 45~55 minutes of psychomotor therapy 2~3 times per week for 12 weeks. The control group received the same psychomotor therapy after the study. Positive and Negative Symptom Scale （PANSS）， Scales of Social-skills for Psychiatric Inpatient （SSPI） and Insight and Treatment Attitude Questionnaire （ITAQ） were used to assess the patients before the intervention and at 4^th， 8^th and 12^th week after the intervention. ResultsThe main effects of intervention at different time points for PANSS positive symptoms， negative symptoms and general psychopathology subscale scores， PANSS total score， SSPI score and ITAQ score were all statistically significant （F=33.989， 204.245， 82.817， 279.596， 26.144， 7.463， P<0.01）. Furthermore， statistically significant between-group differences were observed in PANSS negative symptoms and general psychopathology subscale scores， PANSS total score， SSPI score and ITAQ score （F=30.053， 5.306， 33.417， 33.013， 18.608， P<0.05 or 0.01）. Moreover， the interaction effect of time and group were statistically significant for PANSS positive symptoms， negative symptoms and general psychopathology subscale score， PANSS total score and SSPI score （F=3.472， 9.798， 3.843， 14.390， 20.661， P<0.05 or 0.01）. After 12 weeks of intervention， the research group exhibited statistically significantly lower PANSS total score and subscale scores compared with baseline （P<0.01）， while their SSPI total score was significantly higher than that of control group（P<0.01）. Additionally， compared with the control group， the research group had statistically significantly lower PANSS total score and subscale scores ， while their SSPI score was statistically significantly higher than those of control group（P<0.01）. ConclusionPsychomotor therapy may contribute to the improvement of the psychiatric symptoms and social function in young and middle-aged inpatients with schizophrenia， enhancing their rehabilitation outcomes. ［Funded by Health Commission Scientific Research Project of Wuhu （number， WHWJ2021y073）］

Oxidative stress injury and mitochondrial dysfunction are major obstacles to neurological functional recovery after ischemic stroke. The development of new approaches to simultaneously diminish oxidative stress and resist mitochondrial dysfunction is urgently needed. Inspired by the overproduced reactive oxygen species (ROS) at ischemic neuron mitochondria, multifunctional nanoparticles with ROS-responsiveness and mitochondrial-targeted (SPNPs) were engineered, achieving specific targeting delivery and controllable drug release at ischemic penumbra. Due to the nose-to-brain pathway, SPNPs which were encapsulated in a thermo-sensitive gel by intranasal administration were directly delivered to the ischemic penumbra bypassing the blood‒brain barrier (BBB) and enhancing delivery efficiency. The potential of SPNPs for ischemic stroke treatment was systematically evaluated in vitro and in rat models of middle cerebral artery occlusion (MCAO). Results demonstrated the mitochondrial-targeted and protective effects of SPNPs on H₂O₂-induced oxidative damage in SH-SY5Y cells. In vivo distribution analyzed by fluorescence imaging proved the rapid and enhanced active targeting of SPNPs to the ischemic area in MCAO rats. SPNPs by intranasal administration exhibited superior therapeutic efficacy by alleviating oxidative stress, diminishing inflammation, repairing mitochondrial function, and decreasing apoptosis. This strategy provided a multifunctional delivery system for the effective treatment of ischemic injury, which also implies a potential application prospect for other central nervous diseases.

Objective:To explore differences in clinical characteristics and hemoglobin levels between different age groups in patients with metabolic-associated fatty liver disease (MAFLD) at high and low altitude areas, so as to provide a basis for further research on the effect of chronic hypoxia on MAFLD.Methods:Liver function indexes, non-invasive fibrosis indexes, metabolic indexes, and routine blood test of 1 458 (Xining area of Qinghai province) and 1 633 cases (Huzhou area, Zhejiang province) with MAFLD who underwent physical examination were retrospectively analyzed. The total population of the two places were compared and analyzed with the hemoglobin reference limit of 180 g/L. The population of Xining was divided into high and low hemoglobin groups for comparative analysis. The population of the two places was divided into five groups according to age stratification (≤30 years old, 31-40 years old, 41-50 years old, 51-60 years old, ≥61 years old). After multivariate adjustment, the characteristics of high and low hemoglobin groups and MAFLD were compared between the two groups. Statistical analysis was performed with t-test or χ2 test. Results:The detected indexes values observed were higher in Xining than Huzhou area population [fibrosis indexes (FIB4, 1.08±0.02 vs. 1.19±0.02), erythrocyte (5.14±0.13 vs. 5.30±0.13), hemoglobin (156.82±0.37 vs. 164.19± 0.39), alanine aminotransferase (ALT, 33.70±0.66 vs. 43.68±0.70), aspartate aminotransferase (AST, 24.34±0.28 vs. 29.23±0.30), γ-glutamyltransferase (42.40±1.02 vs. 51.82±1.53), alkaline phosphatase (77.92±0.56 vs. 84.63±0.85), triglyceride (TG, 2.07±0.04 vs. 2.74±0.05), uric acid (UA, 383.42±2.15 vs. 406.44±2.36)]. The detected indexes values observed were higher in Huzhou than Xining area population [platelet count (220.54±1.32 vs. 181.62±1.40), total cholesterol (TC, 5.10±0.02 vs. 5.04±0.03), fasting blood glucose (FBG, 5.67±0.04 vs. 5.29±0.04)]. The differences were statistically significant ( P<0.01). Xining population UA and body mass index were increased in high hemoglobin group than low hemoglobin group, and the other parameters difference were not statistically significant. After the population in Xining was grouped by age, high and low FIB4, ALT, and AST and UA levels were detected in the age group of 31-40 and 51-60 years old, >61 years old, 31-40 years old, and the difference between hemoglobin groups were statistically significant ( P<0.01). Conclusion:Patients with MAFLD are more likely to develop fibrosis, liver function impairment, metabolic disorders and so on under high-altitude hypoxic environment. Additionally, there is certain correlation with disease severity and age changes, suggesting that chronic hypoxia can accelerate MAFLD progression.

【Objective】 To reveal possible mechanisms of miRNA in diabetic hepatopathy through bioinformatics method. 【Methods】 Subset data of miRNA and their matched mRNAs in the liver of STZ-induced diabetic mice and the normal liver tissues of congenial mice by detecting on microarrays were collected from GEO database； information from the database and bioinformatics analysis were applied to mine a batch of miRNAs in diabetic hepatopathy and targeted mRNAs regulated. Then qRT-PCR was used to verify the expressions of miRNAs in diabetic liver from 20 STZ-treated Kunming mice and 10 normal homologous mice. 【Results】 Via detection and analysis， miRNAs differentially expressed （including 96 up-regulated and 77 down-regulated） were significantly obtained. Groups of miRNAs and their effectors （mRNAs） that may be related to the pathological process of diabetic liver disease in mice were screened by GO and KEGG enrichment analyses， combined with relevant protein annotations in the databases and references. The expressions of miR-200a-3p， miR-200b-3p and miR-222-3p in the mice’s liver tissue detected by qRT-PCR were significantly down-regulated. In addition， the expressions of related effector genes CERS6， MYBL1， SCD2， SLCO1A4 and PLK2 were up-regulated， while the expressions of ACSS2， BCL6 and SLC10A2 were down-regulated. 【Conclusion】 The variation trend of those candidate miRNAs in mouse diabetic liver compared with that in control livers was consistent with that of the previous studies and prediction， which revealed their potential molecular regulation in this disease process.
