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.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

Objective To investigate the mechanism of electroacupuncture to improve gastric motility in functional dyspep-sia(FD)model rats by regulating enteric nervous system through PI3K/Akt signaling pathway.Methods SPF grade SD rats were used and randomly divided into blank group,model group,and electroacupuncture group.The multifactorial stress inter-vention method was used in model group and electroacupuncture group to construct the FD rat model,and the modeling period was 14 days.After successful modeling,the electroacupuncture group was treated with electroacupuncture on the ST 36 and LR3 for 10 days.The body weight and food intake of the rats were measured three times at the beginning of the experiment(0 d),at the end of the modeling period(14 d),and at the end of the electroacupuncture intervention(24 d),respectively.At the end of the intervention,the intragastric residual rate,the morphological structure of gastric antrum,and the protein expression levels and locations of PI3K,Akt,and GFAP in the gastric antrum tissue were measured in each group of rats.Results ① Before modeling,the difference between the body weight of rats in each group was not statistically significant(all P＞0.05).After elec-troacupuncture intervention,the body weight ranking of rats in each group was blank group＞electroacupuncture group＞mod-el group,and the differences between groups were all statistically significant(all P＜0.01).② Before modeling,the difference between the body intake of rats in each group was not statistically significant(all P＞0.05).After electroacupuncture interven-tion,the ranking of food intake of rats in each group was blank group＞electroacupuncture group＞model group,and the differ-ences between groups were all statistically significant(all P＜0.01).③ The ranking of intragastric residual rate of rats in each group was blank group＜electroacupuncture group＜model group,and the differences between groups were all statistically sig-nificant(all P＜0.05).④ There was no organic lesions such as hemorrhage,edema,or ulcer in the gastric antrum tissue of rats in each group.⑤The ranking of protein expression levels of PI3K and Akt in gastric antrum tissue of rats in each group was blank group＞the electroacupuncture group＞the model group,and the differences between the groups were all statistically sig-nificant(all P＜0.05).PI3K and Akt proteins were all expressed in the muscular layer of gastric antrum tissue.⑥The ranking of enteric glial cell(EGC)counting in the gastric antrum tissue of rats in each group was blank group＞electroacupuncture group＞model group,and the differences between groups were all statistically significant(all P＜0.05).Conclusion The mech-anism that electroacupuncture can improve gastric motility in FD model rats may be related to activation of PI3K/Akt signaling pathway in the muscle layer of gastric antrum tissue,upregulation of EGC,and improvement of enteric nervous system function.

Objective To explore the mechanism of electroacupuncture in alleviating hyperlipidemia in a rat model by modulating mammalian target of rapamycin complex 1(mTORC1)-mediated lipophagy in hepatocytes.Methods A total of 30 SD rats were randomly divided into blank(n=6)and modeling groups(n=24)using the random number table method.A hyperlipidemic rat model was established by feeding rats a high-fat diet(feeding for 8 weeks).After successful modeling,the modeling group was randomly divided into the model,electroacupuncture,mTORC1 inhibitor,and electroacupuncture+mTORC1 agonist groups,with six rats in each group.Except for the blank group,all other rats were fed with high fat diet.Rats in the electroacupuncture and electroacupuncture+mTORC1 agonist groups received electroacupuncture intervention at bilateral"Fenglong"(ST40)acupoints(dilatational wave 2 Hz/100 Hz,current intensity 1 mA)for 30 min once daily.Rats in the mTORC1 inhibitor group received intraperitoneal injections of the mTORC1 inhibitor,rapamycin(2 mg/kg),once daily.Rats in the electroacupuncture+mTORC1 agonist group received intraperitoneal injections of the mTORC1 agonist MHY1485(10 mg/kg)once daily.The interventions were administered for five consecutive days per week for 4 weeks.Upon completion of the intervention,the following analyses were performed:serum contents of total cholesterol(TC),triglycerides(TAG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),free fatty acids(FFA),alanine aminotransferase(ALT),and aspartate aminotransferase(AST)were measured using a fully automated biochemical analyzer.Hepatic histopathological changes and lipid deposition were observed using hematoxylin-eosin and oil red O staining.The liver condition was observed and the liver index was calculated.Hepatic TC and TAG levels were measured using an enzyme-linked immunosorbent assay.The ultrastructure of the liver tissue was observed using transmission electron microscopy,and the mean fluorescence intensity of perilipin 2(PLIN2)and microtubule-associated protein 1 light chain 3(LC3)-Ⅱ in the liver tissue was detected using immunofluorescence.Protein expression of LC3-Ⅱ/LC3-Ⅰ,phosphorylated mammalian target of rapamycin(p-mTOR)/mTOR,and mTORC1 in liver tissue was detected using Western blotting.Results Compared to the blank group,the model group rats showed increased serum TC,TAG,LDL-C,ALT,AST,and FFA levels,along with decreased HDL-C levels(P<0.05).The liver index and hepatic TC and TAG levels were also elevated(P<0.05).Histological examination of liver tissue revealed substantial lipid accumulation,numerous lipid droplets within hepatocytes,abnormal mitochondrial morphology,and scarce autophagic vacuole.The mean fluorescence intensity of PLIN2 increased,whereas that of LC3-Ⅱ decreased(P<0.05).Additionally,the LC3-Ⅱ/LC3-Ⅰ ratio was reduced,whereas the p-mTOR/mTOR ratio and mTORC1 protein expression were increased(P<0.05).Compared to the model group,rats in the mTORC1 inhibitor and electroacupuncture groups exhibited decreased serum TC,TAG,LDL-C,ALT,AST,and FFA levels(P<0.05),along with a reduced liver index and hepatic TC and TAG levels(P<0.05).Histological examination showed markedly attenuated lipid accumulation and visible autophagic vacuole in the hepatocytes.The mean fluorescence intensity of PLIN2 decreased,whereas that of LC3-Ⅱ increased(P<0.05).Moreover,the LC3-Ⅱ/LC3-Ⅰ ratio increased,whereas the p-mTOR/mTOR ratio and mTORC1 protein expression decreased(P<0.05).In comparison with both the electroacupuncture and mTORC1 inhibitor groups,the electroacupuncture+mTORC1 agonist group demonstrated increased serum TAG,TC,LDL-C,ALT,AST,and FFA levels(P<0.05)as well as elevated liver index and hepatic TC and TAG levels(P<0.05).Liver tissues exhibited aggravated lipid deposition and absence of autophagic vacuole in liver cells.The mean fluorescence intensity of PLIN2 was enhanced,whereas that of LC3-Ⅱ was reduced(P<0.05).Furthermore,the LC3-Ⅱ/LC3-Ⅰ ratio decreased,and the p-mTOR/mTOR ratio and mTORC1 protein expression increased(P<0.05).Conclusion Electroacupuncture at"Fenglong"(ST40)may improve blood lipid levels in hyperlipidemic rats by inhibiting mTORC1 and promoting hepatocyte lipophagy.

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.
