Objective: To understand the hydration status and related factors of rural boarding primary school students, so as to provide a scientific basis for drinking water health intervention for primary school students. Methods: In November 2023, a convenience sampling approach was employed to conduct a hydration status survey among 144 boarding students in grades 5 and 6 of a rural primary school in Guangxi. The Duplicate meal method and weighing method were utilized to measure the food derived water intake over three consecutive days. Urine osmolarity of students was measured on site for three days, and a simple physical examination was also carried out. A self administered questionnaire was used to investigate students drinking water literacy, daily water intake, and physical activity levels. Meanwhile, a drinking water literacy survey was conducted among 21 substitute teachers and 144 parents of the boarding students in grades 5 and 6. Logistic regression was used to identify factors associated with students hydration status. Results: The median daily total water intake of students was 2 043.55 mL, and 54.86% of the students did not reach the recommended Adequate Intake (AI). The median food derived water intake was 1 149.24 mL, accounting for 53.94% of the total water intake. Univariate analysis revealed that the daily drinking frequency, daily water intake, and food derived water intake of students were related factors of hydration status ( β =-1.60, -1.01, -0.00, all P <0.05). Multivariate Logistic regression analysis showed that primary school students with a daily drinking frequency of ≥7 times were more likely to maintain an adequate hydration status ( OR =0.28, 95% CI =0.09-0.93, P ＜0.05). Conclusions The water intake from food is the main source of water in the body for boarding primary school students in a certain rural school in Guangxi. Primary school students should increase their water intake frequency appropriately to maintain an adequate hydration status.

This study aimed to investigate the effect of atractylenolide I (Atr-I) on myocardial mitochondrial function in mice with dilated cardiomyopathy (DCM) by regulating the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) pathway. Sixty SPF-grade male cTnT R141W transgenic DCM mice were randomly divided into the DCM group, Atr-I low-dose group (60 mg/kg), Atr-I high-dose group (240 mg/kg), captopril group (0.01 g/kg), and Atr-I high-dose+cGAS/STING pathway activator 5,6-dimethylxanthenone-4-acetic acid (DMXAA) group, with 12 mice in each group. Additionally, 12 male C57BL/6J mice were used as the control group. All mice were administered via oral gavage once daily for 8 weeks. Cardiac function was assessed using the Vevo 770 ultrasound system; myocardial pathology was examined via HE staining; mitochondrial ultrastructure in cardiomyocytes was observed using transmission electron microscopy; the proportion of cardiomyocytes without reduced mitochondrial membrane potential was detected using JC-1 staining; reactive oxygen species (ROS) content in myocardial tissue was measured using 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) staining; adenosine triphosphate (ATP) content in myocardial tissue was determined using a commercial kit; and Western blot was performed to detect the protein expression levels of mitofusin-2 (MFN2), dynamin-related protein 1 (DRP1), cGAS, STING, interferon-β (IFN-β), CXC chemokine ligand 10 (CXCL10), and interleukin-6 (IL-6) in myocardial tissue. The aim was to observe the effect of Atr-I on myocardial mitochondrial function in DCM mice. The results showed that low- and high-dose Atr-I (60 mg/kg, 240 mg/kg) intervention improved cardiac function, alleviated cardiomyocyte hypertrophy and disordered muscle fiber arrangement, ameliorated mitochondrial ultrastructure in cardiomyocytes, reduced ROS content and the protein expression levels of DRP1, cGAS, STING, IFN-β, CXCL10, and IL-6 in myocardial tissue, and increased the proportion of cardiomyocytes without reduced mitochondrial membrane potential, as well as ATP content and MFN2 protein expression in myocardial tissue. However, DMXAA attenuated the beneficial effects of high-dose Atr-I on myocardial mitochondrial function in DCM mice. In conclusion, Atr-I may improve myocardial mitochondrial function in DCM mice by inhibiting the cGAS/STING pathway.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Objective: To investigate the current status of knowledge, attitudes and practices regarding drinking water among primary school students in rural areas of China, so as to provide scientific basis for implementing health interventions related to drinking water. Methods: From November to December 2023, a stratified cluster random sampling method was employed to select 6 354 fourth to sixth grade primary school students in Shanxi, Zhejiang, Jiangxi, Guangxi and Gansu for a questionnaire survey. A uniformly designed questionnaire (including basic information, drinking water-related knowledge, attitudes and practices indicators) was distributed and completed by the students themselves. The χ 2 test was used to analyze the differences in drinking water-related indicators among students of different gender and boarder, and Logistic regression was used to analyze the influencing factors of drinking water practices among students. Results: Among the indicators of drinking water knowledge, the awareness rate of appropriate daily water intake for respective student age groups was the lowest (27.90%). The awareness rate among nonresident students was significantly higher than that among boarding students (31.29%, 15.49%, χ 2=132.75, P <0.01). Regarding attitudes toward drinking water, 13.33% of the students believed that well water or tap water could be drunk directly, and 9.58% believed that going to the toilet at school was troublesome. Regarding practices, the self-reported water intake among students was 1 000 (600, 1 200) mL. The results of multifactorial Logistic regression showed that higher grades ( OR=1.60, 95%CI =1.34-1.92), nonresident students ( OR=1.32, 95%CI = 1.15 -1.52), northern region ( OR=1.43, 95%CI =1.27-1.61), knowledge of appropriate daily water intake ( OR=1.41, 95%CI =1.24-1.60), drinking temperature ( OR=1.43, 95%CI =1.28-1.60), scientific hydration methods ( OR=1.25, 95%CI =1.08- 1.44 ), and adopting scientific hydration methods regularly ( OR=1.75, 95%CI =1.50-2.04) were the independent influences on daily water intake attainment ( P <0.05). Conclusions Rural primary school students lack knowledge about healthy drinking water, have cognitive biases about safe drinking water and exhibit unhealthy drinking behavior. It is suggested that health education be carried out in combination with the characteristics of students to enhance their drinking water literacy.

Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM_2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Objective To investigate the feasibility of using the cell-free DNA(cfDNA)carrying tissue-specific mutations as biomarkers for assessing the severity of exercise-induced tissue injury.Methods Based on a public gene expression database,ten tissue-specific and highly-expressed genes were selected for each of ten different human tissues.A total of 34 young healthy volunteers were recruited,and their peripheral blood samples were collected after running 5 km per day for one week.Genomic DNA from leukocytes,plasma exosomal RNA,and plasma cfDNA were extracted and subjected to high-throughput sequencing respectively.Tissue-specific somatic mutations in plasma exosomal RNA were identified,and the relationship between cfDNA carrying these mutations and traditional protein biomarkers was analyzed.Results Tissue-specific cfDNA mutations related to five tissues(myocardium,skeletal muscle,intestine,stomach,and kidney)were detected in more than five volunteers.The correlation coefficients between total plasma cfDNA levels and the levels of tissue-specific protein biomarkers associated with these five tissues were less than 0.3(n=34,r=-0.51-0.28,P=0.0022-0.65).Notably,for each specific tissue,the levels of tissue-specific cfDNA mutations were positively correlated with the corresponding protein biomarker levels,and correlation coefficients were over 0.8(n=7-13,r=0.81-0.92,P=9.0×10-4-0.020).Conclusion Tissue-specific cfDNA mutations may serve as novel potential biomarkers for non-invasive evaluation of exercise-related tissue injury.
