Objective: To explore the relationship between sleep characteristics, physical activity patterns, with depressive and anxiety symptoms in college students, so as to provide reference for student mental health promotion. Methods: From September to November 2023, a convenience sampling method was used to select 7 954 college students aged 18-22 years from 9 universities in Shanghai, Hubei, and Jiangxi. Assessments were conducted using the International Physical Activity Questionnaire Short-Form (IPAQ-SF), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Scale-7 (GAD-7), and Pittsburgh Sleep Quality Index (PSQI) to evaluate physical activity, depressive and anxiety symptoms, and sleep quality, respectively. Logistic regression analysis was employed to explore the impact of sleep characteristics and physical activity patterns on depressive and anxiety symptoms and their comorbidity among college students. Results: The detection rates for depressive symptoms, anxiety symptoms, and comorbid depression and anxiety symptoms were 25.67%, 35.39%, and 23.15%, respectively. Factors such as gender, grade, household registration, parental education level, annual family income, family structure, and dietary habits were all associated with the detection rates of depressive and anxiety symptoms and their comorbidity (χ2=4.41-118.39, P<0.05). Physical activity patterns, sleep duration, sleep quality, and sleepwake characteristics were also associated with the occurrence of depressive and anxiety symptoms and their comorbidity (χ2=9.66-627.70, P<0.05). Logistic regression analysis showed that college students who stayed up late and slept less than 7 had the highest risk of depressive and anxiety symptoms and their comorbidity (OR=1.93, 1.85, 1.88, P<0.05). Compared to regular physical activity patterns, insufficient physical activity patterns were associated with an increased risk of depressive and anxiety symptoms (all OR=1.18, P<0.05). Further stratified analysis results showed that the risk of depression, anxiety and their comorbidity increased in college students who stayed up late and slept less than 7 h, went to bed before midnight and slept less than 7 h, or went to bed before midnight and slept more than 7 h but did not have sufficient physical activity (P<0.05). Conclusions Sleep characteristics and physical activity patterns significantly affect depressive and anxiety symptoms in college students. Universities should strengthen sleep management and implement flexible physical activity interventions to help students establish healthy lifestyles.

ObjectiveTo analyze the epidemiological characteristics of pathogens in foodborne disease cases in Haining City， Zhejiang Province， and to provide a basis for the prevention and investigation of foodborne diseases and outbreak events. MethodsInformation on foodborne disease patients from 2014 to 2023 was collected， and stool or anal swab samples were tested for relevant pathogens. The χ² test was used to compare the differences in pathogen detection rates among different groups， and multivariate logistic regression analysis was used to analyze the risk factors for pathogen detection. ResultsA total of 5 814 samples were tested， with a positive detection rate of 15.36%. The detection rates were 4.95% for norovirus， 4.49% for Escherichia coli， 3.59% for Salmonella， 2.22% for Vibrio parahaemolyticus， and 0.11% for Shigella. The positive detection rates showed seasonal characteristics， with a minor peak in March-April dominated by norovirus and a major peak in July-September dominated by bacteria. The three groups with the highest detection rates were workers， white-collar workers and other groups. Multivariate logistic regression analysis showed that age， season， and antibiotic use before consultation were significant influencing factors for pathogen detection （P<0.05）. Total pathogen detection risk was lower in the group that took antibiotics before visiting the clinic compared to those who did not （OR=0.29， 95%CI： 0.15‒0.49）. The detection risk for norovirus was lower in the preschool age group （OR=0.19， 95%CI： 0.04‒1.00）， in summer and autumn （OR range 0.23‒0.41）， and in the group taking antibiotics （OR=0.42， 95%CI： 0.15‒0.92）， but higher in the adolescent group （OR=1.40， 95%CI： 1.05‒1.88）. The detection risk for enteropathogenic Escherichia coli was higher in summer （OR=1.82， 95%CI： 1.30‒2.60）. The detection risk for Salmonella increased in the elderly group and in summer （OR range 1.44‒2.21）， but decreased in the adolescent group， in winter， and in the group taking antibiotics （OR range 0.22‒0.65）. The detection risk for Vibrio parahaemolyticus increased in summer and autumn （OR range 1.80‒1.90）， but decreased in the primary and secondary school student group and in winter （OR range 0.10‒0.32）. ConclusionThe prevalence of foodborne disease pathogens in Haining City is relatively high. Age， season， and antibiotic use before consultation are independent influencing factors for pathogen detection. These findings suggest that specific hypotheses regarding pathogenic factors can be proposed based on the time of occurrence and the age distribution of cases during field investigations of foodborne outbreaks.

OBJECTIVE To explore the phenotypic changes and possible mechanisms of lncRNA OIP5-AS1 on the proliferation, migration, apoptosis, invasion and cycle of ovarian epithelial cells IOSE80. METHODS The clinical data of patients were collected from TCGA database and GEO database. After R package analysis, the differential expression of OIP5-AS1 was visualized in the volcanic map. The correlation between survival rate and OIP5-AS1 was analyzed by Kaplan-Meier. The IOSE80 cell model of OIP5-AS1 over expression and silencing was constructed with lentivirus vector. The expression of OIP5-AS1 was verified by RT-qPCR. Cell proliferation was detected by CCK-8. Invasion was detected by Transwell. Cell migration was detected by scratch test. Cell cycle and apoptosis were detected by flow cytometry. Western blotting was used to detect the expression of E-cadherin and N-cadherin, as well as the expression of cyclin-dependent kinase(CDK) and cyclin-G-related kinase(GAK). RESULTS RT-qPCR results showed that IOSE80 cell lines over expressing and silencing OIP5-AS1 were successfully constructed. CCK-8 results showed that overexpressing OIP5-AS1 promoted the proliferation of IOSE80 cells. Scratch test results showed that overexpressing OIP5-AS1 promoted the migration of IOSE80 cells. Transwell results showed that overexpressing OIP5-AS1 would increase the invasiveness of IOSE80 cells. Flow cytometry results showed that overexpression of OIP5-AS1 weakened the apoptosis of IOSE80 cells and promoted the progress of cell cycle. Western blotting results showed that overexpression of OIP5-AS1 downregulated the expression of E-cadherin and upregulated the expression of N-cadherin, while overexpression of OIP5-AS1 increased the expression of CDK and GAK proteins. CONCLUSION LncRNA OIP5-AS1 further interferes with the regulation of IOSE80 cell cycle by up regulating the expression of CDK and GAK, and then indirectly regulates the malignant phenotype of ovarian epithelial cells.

OBJECTIVE To explore the effects and potential mechanism of evodiamine on inflammatory response and apoptosis of epithelial cells in asthma model rats. METHODS SD rats were separated into control group， model group， evodiamine low-dose group （10 mg/kg）， evodiamine high-dose group （20 mg/kg）， dexamethasone group （positive control， 0.5 mg/kg）， epidermal growth factor （EGF） group [mitogen-activated protein kinase （MAPK） activator， 10 μg]， evodiamine high-dose+EGF group （20 mg/kg evodiamine+10 μg EGF）， with 10 rats in each group. Except for the control group， the other groups were sensitized by 3-point injection of 10% ovalbumin（OVA）-aluminium hydroxide mixture and stimulated by inhalation of 2%OVA nebulized liquid to establish an asthma model. The count of inflammatory cells （macrophages and lymphocytes） in bronchoalveolar lavage fluid （BALF） was detected in each group； pathological changes of lung tissue in rats were observed； the apoptosis of airway epithelial cells， the levels of serum inflammatory factors [tumor necrosis factor-α， interleukin-6 （IL-6） and IL-4]， the expressions of pathway-related proteins p38 MAPK， phosphorylated p38 MAPK （p-p38 MAPK）， signal transduction and transcription activating factor 1 （STAT1）] and apoptosis-related proteins [B cell lymphoma-2 （Bcl-2） and Bcl-2 associated X protein （Bax）] were all detected in lung tissue. RESULTS Compared with the control group， bronchial mucosal edema， thickening of alveolar septa and extensive infiltration of inflammatory cells were observed in the lung tissue of rats in the model group； the number of inflammatory cells， apoptosis rate of airway epithelial cells， the levels of inflammatory factors， p-38 MAPK/p-38 MAPK， and the protein expressions of Bax and STAT1 were increased significantly； the expressions of Bcl-2 protein and Bcl-2/Bax were reduced significantly （P＜0.05）. Compared with the model group， the pathological changes in lung tissues were alleviated to varying degrees in evodiamine low-dose and high-dose groups， and dexamethasone groups， and the above indicators were significantly reversed. However， the change trends of corresponding indicators in the EGF group were opposite to the above （P＜0.05）. EGF could significantly attenuate the effect of high-dose evodiamine on inflammatory response in asthmatic rats （P＜0.05）. CONCLUSIONS Evodiamine can relieve inflammatory reactions and inhibit the apoptosis of airway epithelial cells in asthmatic rats， the mechanism of which may be associated with inhibiting p38 MAPK/STAT1 signaling pathway.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Arsenic, a naturally occurring metal-like chemical element, is one of the 10 chemicals of major public concerns listed by the World Health Organization as harmful to the environment and human health. It can enter the human body through breathing, intaking food, drinking water, skin exposure, and other ways, and long-term exposure to arsenic can cause cancer of multiple organs and impaired function of multiple systems. Epigenetic mechanisms play an important role in arsenic-induced health effects, and research suggested that the carcinogenicity of arsenic may be associated with epigenetic changes. Previous studies focused on the effects of arsenic on DNA methylation modification. In recent years, research showed that 5-hydroxymethylcytosine (5-hmC), an intermediate of active demethylation of DNA, can act as a sensitive epigenetic mark and play a crucial role as a "bridge" between arsenic exposure and health effects. Based on the latest research progress on the role of DNA hydroxymethylation in the health effects associated with arsenic exposure, this article briefly described the relationship between the health effects of arsenic exposure and DNA hydroxymethylation, summarized the possible mechanisms of DNA hydroxymethylation in the health effects associated with arsenic exposure, and provided a scientific basis for preventing and treating the health effects associated with arsenic exposure.
