Objective:To investigate the exposure to tobacco advertisement/promotion and smoking scenes from television/movie/video among middle school students in Zhejiang Province in 2021, and the influence on the knowledge and behavior about smoking of the students.Methods:Total 7 692 students were selected from 60 middle schools with the proportional probability sampling (PPS) method in Zhejiang Province. The investigation was performed with self-administered questionnaire survey which consisted of tobacco use, exposure to tobacco advertisement/promotion, et. The collected data was weighted and analyzed using the complex survey module of SPSS 21.0 software.Results:The prevalence of exposure to tobacco advertisement/promotion and smoking scenes from television/movie/video among the middle school students were 24.8% and 63.8% respectively. In recent 30 d, among those who had been exposed to the tobacco retail point, the proportion of those exposed to tobacco advertisement/promotion was 46.1%, and among those who surfed the internet, the proportion of those exposed to tobacco advertisement/video was 23.4%. Among the whole students, the proportion of those exposed to free tobacco product was 2.4%. The junior middle school students, regular high school students, and vocational school students who had been exposed to tobacco advertisement/promotion were more likely to feel smoking more comfortable in social occasions (5.6%, 6.7%, 8.8%), to feel smoking attractive for the young (9.1%, 8.4%, 8.8%), and also had higher rate of attempted smoking (12.5%, 16.9%, 20.5%) than non-exposed ones (junior middle school students: 2.3%, 5.5%, 4.8%; regular high school students: 2.9%, 2.9%, 9.8%; vocational school students: 4.0%, 4.0%, 15.3%) (all P<0.05). Among the students who had seen television/movie/video within 30 days, the junior middle school students, regular high school students, and vocational school students who had been exposed to smoking-related scenes had higher rate of attempted smoking (8.1%, 14.7%, 20.0%) than non-exposed ones (5.4%, 8.0%, 10.6%) (all P<0.05). Conclusion:The prevalence of exposure to tobacco advertisement/promotion and smoking scenes from television/movie/video are relatively high among the middle school students in Zhejiang province, which make exposed students more likely to report positive attitude to tobacco use, and more likely to smoke, to attempt to smoke.

Intracerebral hemorrhage (ICH) is a hemorrhagic cerebrovascular disease with high incidence and mortality. Oxidative stress response plays an important role in the pathological and physiological processes of ICH, and is also a potential effective target for clinical treatment. In this paper, the pathogenesis of oxidative stress after ICH, mechanism of nerve and vascular injury in oxidative stress, and detection and treatment of oxidative stress are reviewed in order to provide references for basic research and clinical practice in ICH.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

In recent years， NOD-like receptor protein 3 （NLRP3） inflammasome in tumors has become a research hotspot， especially in melanoma， colorectal cancer， lung cancer， and breast cancer， and more and more evidence has shown that inflammation plays a role in the development， progression， angiogenesis， and invasion of cancer. Hepatocellular carcinoma （HCC） is the most common type of primary liver cancer， and there are still controversies over the role of NLRP3 inflammasome in the development and progression of HCC. Therefore， this article reviews the potential impact of NLRP3 inflammasome in the progression of HCC and its mechanism of action in anticancer therapy， and it is believed that NLRP3 inflammasome can be used as an effective therapeutic target for HCC patients.

Objective To analyze the effects of miR-181a-5p overexpression on metabolites in the small intestines of mice with subcutaneous oral cancer by detecting changes in metabolites and metabolic pathways.Methods Three groups were included in study:Control group,negative control and miR-181a-5p overexpression group.To establish a subcutaneous oral cancer model in mice,variously treated cell suspensions were subcutaneously injected into the upper right of the groin in female M-NSG severely immunodeficient mice.Changes in pathology and small intestinal tissues were assessed by HE staining.Changes in mouse body weight were also assessed.Tandem orbitrap mass spectrometry and ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry,were used to examine metabolites in the small intestines.By pre-analyzing the original data and quality rating sample data,XCMS was able to assess which metabolites were different among the groups.To identify unique metabolic pathways,KEGG enrichment analysis was used.Results A total of 170 distinct metabolites were found in the small intestinal tissues of Control and NC groups.Choline metabolism,alanine,aspartate,and glutamate metabolism,GABA synaptic metabolism,glycerophospholipid metabolism,cAMP signaling route,cancer center carbon metabolism,and niacin and niacin amine metabolic pathways were important signaling pathways for metabolite enrichment.In the NC group,16 distinct metabolites with VIP values larger than 2 were found in the small intestines compared with the OE group overexpressing miR-181a-5p.Glycerin phosphorylcholine,palmitic acid,3-hydroxybutyl carnitine,and β-hydroxybutyric acid were among the metabolites that significantly varied.The primary enhanced metabolic pathway was the choline pathway.Conclusions Mouse small intestines underwent slight changes from subcutaneous oral cancer with the greatest effect on metabolites critical for energy metabolism.The choline metabolic pathway was the pathway that selected absolutely metabolites in mouse small intestines with subcutaneous grafts of oral cancer.

Objective:To investigate the level of health literacy and its influencing factors among residents aged 15-69 years with different chronic disease in Zhejiang Province.Methods:In this cross-sectional study, a stratified multistage whole cluster random sampling method was used to select 19 200 permanent residents aged 15-69 years from 30 monitoring sites in Zhejiang Province from June to November 2022, and a household questionnaire survey was carried out with the National Health Literacy Monitoring Questionnaire for the Population. The content of the survey included socio-demographic characteristics, health-related factors and health literacy level. A total of 19 200 questionnaires were distributed and 19 051 were collected, of which 18 857 (98.98%) were valid. The χ2 test was used to compare the health literacy levels of residents with different chronic diseases, and logistic regression was used to analyze the influencing factors of the health literacy levels. Results:The health literacy level of residents aged 15-69 in Zhejiang Province in 2022 was 38.36%. Among them, the health literacy level of patients with multiple chronic diseases was much lower than those with single chronic disease and those without chronic disease (14.70% vs 25.37%, 42.21%) ( χ2=483.05, P<0.001). It was positively associated between having multiple chronic diseases and insufficient health literacy ( OR=1.26, 95% CI: 1.01-1.58); compared with those without chronic disease ( OR=1.00), patients with multiple chronic diseases were significantly more likely to have inadequate health literacy in basic knowledge and concepts ( OR=1.29, 95% CI: 1.03-1.63), health behaviors ( OR=1.24, 95% CI: 1.01-1.53), basic skills ( OR=1.37, 95% CI: 1.11-1.69), and health information literacy ( OR=1.27, 95% CI: 1.08-1.50). Conclusions:The number of chronic diseases is a key factor that affects the residents′ health literacy level, and people with multiple chronic diseases are often associated with a higher risk of inadequate health literacy.

Animal model of hydrocephalus is an important object to study the mechanism, pathological characteristics, and treatment of hydrocephalus. A stable and controllable animal model in accordance with clinical development of hydrocephalus can help to develope hydrocephalus related basic research and clinical translational application. According to the study purpose and genetic and physiological characteristics of experimental animals, a variety of animals have been used to establish different types of hydrocephalus animal models. The methods for congenital hydrocephalus models include gene edition and metabolic induction, while secondary hydrocephalus models can be induced by blocking the circulation of cerebrospinal fluid and interfering cerebrospinal fluid absorption. The hydrocephalus models constructed by different methods are also different in progression, neurofunctional changes, and histopathological characteristics. This paper reviews the construction methods and pathological characteristics of various hydrocephalus models in order to provide references for selection of animal models for hydrocephalus-related research.

Objective:To describe the prevalence of tobacco use among college students in Zhejiang Province and analyze the influencing factors of second-hand smoke exposure on campus.Methods:In 2021, college students were selected from 9 colleges through stratified multi-stage cluster sampling from Zhejiang Province and surveyed using questionnaire. A total of 6 530 questionnaires were distributed and 6 035 were returned, with 6 030 valid questionnaires (96.48%). A descriptive analysis of the demography characteristics, cigarettes and electronic cigarettes (e-cigarettes) use, and second-hand smoke exposure of the subjects was carried out, and chi-square test was used for statistical analysis and multivariate logistic regression analysis was used to analyze influencing factors of second-hand smoke exposure on campus.Results:The current smoking rate and current use rate of e-cigarettes among college students were 3.70% and 1.56%, respectively, and the dual use rate of cigarettes and e-cigarettes was 1.16%. The exposure rate of second-hand smoke among college students on campus was 25.06%, while the exposure rate of second-hand smoke in off campus places was 32.35%. The awareness rates of smoking related diseases among college students were as follows: lung cancer (92.02%), heart disease (73.15%), stroke (72.87%), and impotence (64.08%). The awareness rate of second-hand smoke related diseases were as follows: lung cancer in adults (91.11%), heart disease in adults (78.91%), and lung disease in children (89.35%). The multivariate logistic regression analysis showed that seven factors (including gender, school type, major, grade, smoking ban regulations, smoking scenes, and knowledge about the health hazards of second-hand smoke) had a statistically significant impact on college students′ exposure to second-hand smoke at school [ OR=2.63, 0.67, 0.69, (0.39, 0.60, 0.68), 0.51, 1.74, 0.72] (all P<0.01). Conclusions:The use of cigarettes and e-cigarettes among college students in Zhejiang Province is not optimistic, especially the use rate of e-cigarettes is higher than adult. The status of second-hand smoke exposure among college students remains serious, with male students, non-medical students, students of special programs, and senior college students having more severe second-hand smoke exposure on campus, and students with high awareness of second-hand smoke exposure, less exposure to smoking scenes from media, from college with comprehensive smoke-free regulations are less exposed to second-hand smoke on campus.

Objective: To investigate the prevalence of cigarette and electronic cigarette ( e-cigarette ) use among adults in Zhejiang Province, so as to provide insights into tobacco control. Methods : Thirty study sites were randomly sampled from Zhejiang Province in 2020 using a multi-stage stratified random sampling method, and permanent residents at ages of 15 to 69 years were selected as study subjects. A questionnaire was designed based on the questionnaire for the China Adult Tobacco Survey to collect subjects' demographic characteristics, cigarette and e-cigarette use, smoking cessation and exposure to secondhand smoke ( SHS ). The weighted prevalence of smoking, current smoking, current e-cigarette smoking, smoking cessation and exposure to SHS was estimated based on the Seventh National Population Census in 2020. Results : A total of 19 200 questionnaires were recovered, and 19 180 were valid, with an effective recovery rate of 99.90%. The respondents had a mean age of ( 50.30±12.90 ) years, with a male to female ratio of 1∶1.06 and an urban/rural population ratio of 1∶1.31. Among all the respondents, there were 6 033 smokers ( 31.45% ), 4 163 current smokers ( 21.70% ), 201 current e-cigarette users ( 1.05% ), 146 cigarette and e-cigarette dual users ( 0.76% ), 1 870 respondents quitting smoking ( 31.00% of smokers ) and 7 189 respondents with exposure to SHS ( 47.87% of non-smokers ). The weighted prevalence of smoking, current e-cigarette use, cigarette and e-cigarette dual uses, smoking cessation and exposure to SHS was 20.49%, 1.34%, 0.94%, 29.56% and 49.53% in Zhejiang Province, respectively, and the prevalence of current smoking, current e-cigarette use, cigarette and e-cigarette dual uses and exposure to SHS was 40.39%, 2.39%, 1.86% and 55.31% among males and 0.35%, 0.28%, <0.01% and 46.02% among females, respectively. The highest prevalence of current smoking was seen among respondents at ages of 55 to 64 years ( 24.24% ), while the highest prevalence of current e-cigarette use and cigarette and e-cigarette dual uses was seen in adults at ages of 25 to 34 years ( 2.18% and 1.58% ). Conclusions The prevalence of current e-cigarette use was higher among adults in Zhejiang Province in 2020 than the nationwide level in China. The prevalence of cigarette use was lower among adults in Zhejiang Province in 2020 than the nationwide level in China; however, improving the management of tobacco control in public places and the capacity building of smoking cessation services is still required to reduce the use of cigarettes and e-cigarettes.
