ObjectiveTo assess the level of health literacy and its influencing factors among middle school students aged 12‒18 years in Jing’an District, Shanghai, so as to provide a solid scientific foundation for further developing more targeted intervention measures. MethodsA stratified cluster random sampling method was used to randomly select 4 middle schools in Jing’an District, Shanghai from November to December 2023, and conducted a health literacy questionnaire survey on non-graduating middle and high school students, respectively. The2023 Survey on the Status of Health Literacy among Middle School Students in Jing’an District, Shanghai was adopted, which consisted of two parts: health literacy and basic information. Health literacy was divided into three dimensions: health knowledge and concept literacy, healthy lifestyle and behavior literacy, and health skill literacy. Three dimensions could be categorized into six types of health literacy issue: scientific health literacy, infectious disease prevention and control literacy, chronic disease prevention and control literacy, safety and first aid literacy, basic health literacy, and health information literacy. ResultsA total of 1 161 middle school students were enrolled into this study, including 571 males and 570 females. The overall health literacy level of middle school students was 33.51%, with 34.81% among middle school students and 31.69% among high school students, respectively. Results of logistic regression analysis showed that health knowledge acquisition and awareness, as well as application frequency of health knowledge, were the influencing factors for the overall health literacy level among middle school students (P<0.05). The degree of family attention to health maintenance, health knowledge acquisition and awareness, and application frequency of health knowledge were the main influencing factors for the three dimensions and literacy of six types of health issues among middle school students (P<0.05). ConclusionThe levels of different types of health literacy among middle school students in Jing’an District are uneven, with the highest being safety and first aid literacy and the lowest being basic health literacy. It is recommended to take targeted measures to comprehensively improve the health literacy level of middle school students.

ObjectiveTo investigate the antidepressant effect of Sinisan （SNS） by regulating glycogen aynthase kinase-3β （GSK-3β）/tumor necrosis factor alpha-induced protein 3（A20）/CCAAT enhancer binding protein β（C/EBPβ） to inhibit the activation of microglia. MethodA total of 72 male C57/6J mice were randomly divided into the normal group， model group， fluoxetine group （5.0 mg·kg^-1）， low-dose Sinisan group （4.9 g·kg^-1）， medium-dose Sinisan group （9.8 g·kg^-1）， and high-dose Sinisan group （19.6 g·kg^-1）， with 12 mice in each group. After one week of adaptive feeding， chronic unpredictable mild stress （CUMS） was performed to establish the depression model. In the fifth week， drug treatment was conducted for four weeks. In the ninth week， behavioral tests were performed， including sucrose preference test （SPT）， open field test （OPT）， elevated plus maze （EPM） test， and forced swimming test （FST）. Western blot was used to detect the expression levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， nitric oxide synthase （iNOS）， GSK-3β， A20， and C/EBPβ in the cortex. The expression of M1-polarized ionized calcium-binding adapter molecule 1 （Iba1） and cluster of differentiation 68 （CD68） in microglia was detected by immunofluorescence. ResultAfter eight weeks of CUMS， compared with the normal group， the mice in the model group had a significantly reduced sucrose preference rate （P<0.01）， and the activity in the central area of the OPT was significantly reduced （P<0.01）. The activity in the open arm area of the EPM test was significantly reduced （P<0.05）， and the immobility time of FST was increased （P<0.01）. The expression levels of inflammatory proteins IL-1β， IL-6， and iNOS were increased （P<0.01）， and the fluorescence co-localization index of Iba1 and CD68 was increased （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ were significantly increased （P<0.05， P<0.01）. After four weeks of SNS intervention， compared with the model group， the mice in the SNS group had significantly increased sucrose preference rate （P<0.01）， significantly increased activities in the central area and the open arm area in the OPT and the EPM test （P<0.05）， and significantly reduced immobility time in the FST （P< 0.01）. The protein expression levels of IL-1β， IL-6， and iNOS were significantly decreased （P<0.05）， and the fluorescence co-localization index of Iba1 and CD68 was decreased in the high-dose SNS group （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ in the medium-dose and high-dose SNS groups were significantly decreased （P<0.01）， and that of A20 was significantly increased （P<0.01）. ConclusionThe antidepressant effect of SNS is related to the regulation of GSK-3β/A20/C/EBPβ protein expression and the inhibition of M1-type activation of microglia.

Objective:To analyze the occurrence characteristics of heat-related diseases in the 19th Hangzhou Asian Games beach volleyball events, strengthen the ability of prevention and early identification of heat-related diseases, and provide reference for the holding of large-scale outdoor events in summer and reasonable allocation of medical resources.Methods:The medical insurance of heat-related diseases of relevant personnel in the beach volleyball competition from September 19 to September 28, 2023 was retrospectively analyzed, and the incidence of heat-related diseases in the personnel involved in Asia was analyzed.Results:During the beach volleyball competition in Ningbo Region of the Hangzhou Asian Games, a total of 103 people were provided with health services in the medical service field (61 people had mild discomfort due to excessive outdoor temperature; Other cold, minor injury, bandage 42 people); Medical services provided 44 times (4 referrals). Among them, 11 cases were sports injury and trauma (29.5%), 11 cases were heat stroke and other related symptoms (25%), 6 cases were sunburn (13.6%), 10 cases were oral diseases of five senses (22.8%), 4 cases were upper respiratory tract infection (9.1%).Conclusions:The holding of large-scale outdoor events in summer should focus on heat-related diseases, and it is necessary to effectively do the corresponding planning work in advance in terms of reasonable allocation of medical resources and targeted training of professionals.

Objective:To investigate the value of radiotherapy in patients with stage Ⅳ B thoracic esophageal squamous cell carcinoma (ESCC) at initial diagnosis. Methods:A total of 199 patients with stage Ⅳ B thoracic ESCC at initial diagnosis (according to UICC/AJCC Eighth Edition Esophageal and Esophagogastric Junction Cancer TNM Staging) who were treated in the Fourth Hospital of Hebei Medical University between January 2010 to December 2016 were recruited. Winthin the whole group, 130 patients (65.3%) had distant lymph node metastases alone, 51 cases (25.6%) of solid organ metastases alone and 18 cases (9.0%) of solid organ complicated with distant lymph node metastases. Among them, 16 patients (8.0%) were treated with chemotherapy alone, 50 cases (25.1%) of radiotherapy alone, 133 cases (66.8%) of radiochemotherapy (81 patients treated with concurrent radiochemotherapy and 52 patients treated with sequential radiochemotherapy). The survival rate was calculated by Kaplan-Meier method and the difference was analyzed by log-rank test. Clinical prognosis was assessed by multivariate Cox regression model. Results:The median overall survival (OS) of the entire cohort was 12.3 months (95% CI: 10.6-15.4m), and the 1-, 2-, 3-and 5-year OS rates were 52.1%, 25.2%, 19.1%, and 11.5%, respectively. Multivariate analysis showed that tumor length, the number of metastatic organs, and treatment modalities were the independent prognostic factors for OS. There was no significant difference in OS between concurrent radiochemotherapy and sequential radiochemotherapy ( P=0.955). The OS of patients in the radiotherapy dose of ≥6000 cGy group was significantly longer than that of their counterparts in the 4500-5039 cGy and 5040-6000 cGy groups (both P<0.001). Conclusions:For stage Ⅳ B thoracic ESCC patients at initial diagnosis, tumor length ≤3cm, single organ metastasis, and radiochemotherapy strategy are significantly correlated with longer OS. For stage Ⅳ ESCC patients with good physical status, radiotherapy can be supplemented on the basis of systemic chemotherapy. Concurrent or sequential radiochemotherapy needs to be individualized. If patients are tolerable, radiochemotherapy is recommended to the primary tumor or non-regional metastatic lymph nodes, aiming to prolong the OS of patients.

Objective: To observe the variation trend of the peripheral blood lymphocyte-to-monocyte ratio (LMR) during radiotherapy in patients with esophageal cancer and analyze the relationship between LMR and the radiation-induced injury, aiming to provide parameters for accurate evaluation of radiotherapy responses and clinical efficacy. Methods: Clinical data of 248 eligible patients undergoing definitive radiotherapy in our department from January 2013 to December 2015, 248 were retrospectively analyzed. The routine peripheral blood examination was performed weekly before, during and at the end of radiotherapy. The absolute number of lymphocyte and monocyte was recorded to calculate the LMR. The standard classification of LMR value was conducted based on the median value of each parameter. All data including the lesion length, lesion location, clinical stage and LMR were analyzed using the Kaplan-Meier, cox and logistic regression methods, respectively. Results: LMR displayed an exponential decline during radiotherapy. Univariate analysis showed that the average LMR value was the influential factor of overall survival (P=0.011) and progression-free survival (P=0.017). The mean LMR value almost exerted significant effect upon local control rate (P=0.053). No significant correlation was observed between the mean LMR value and radioactive esophagitis and pneumonitis. Stratified analysis based on the results of multivariate analysis demonstrated that patients with higher average LMR value still had longer survival. Logistic regression model revealed that the length of esophageal lesion and irradiation pattern were the influential factors of the mean LMR value. Conclusions LMR value displays an exponential decline during radiotherapy. The greater amplitude prompts the worse prognosis. The wider the irradiation field and the greater decrease in LMR exert more obvious impact on the prognosis.

Objective To investigate the changes of hypoxia-inducible factor (HIF-1α, HIF-2α) expression level in lung cancer A-549 cells under normoxic conditions, different hypoxia durations, and different oxygen concentrations. Methods A549 cells were divided into normoxic group, time control group, and oxygen concentration control group. Western blot was used to detect the expression of HIF-1α and HIF-2α in A-549 cells.Results The expression of HIF-1α and HIF-2α protein were lower under normoxia and significantly increased under hypoxic conditions. The difference was statistically significant. The lower the oxygen concentration, the more HIF-1α and HIF-2α protein expression levels were. The differences between high and high were statistically significant. The expression of HIF-1α protein increased at 2 h after hypoxia, peaked at 8 h, appeared plateau at 8 to 16 h, and decreased at 32 h, with a statistically significant difference. HIF-2α proteins gradually increased with prolonged hypoxia. Conclusions Under hypoxic conditions, the expression of HIF-1α and HIF-2α are increased, and the expression of HIF-2α has a time-dependent pattern, which may have more important biological significance.

Objective To investigate the effects of interferon alpha?2b(IFNα?2b)on serum Hepcidin in hepatitis C patients and its mechanism. Methods Hepatitis C patients were divided evenly into treatment group and control group according to whether they had received treatment with IFNα?2b in the past 3 months. The serum hepci?din was compared between the two groups. HepG2 cells and LO2 cells were treated for 24 hours at varied levels of IFNα?2b(0,50,100,200,400μL)and real?time PCR was used to detect the hepcidin,interleukin?6(IL?6)and signal transduction and transcription activator 3(STAT3)mRNA expression of cells. The protein levels of STAT3 and phosphorylated STAT3(pSTAT3)were measured by Western blot. The changes of these indexes were observed with the gradual increase of IFNα?2b levels. Results Serum Hepcidin level in the treatment group was significantly lower than the control(P<0.05). IFNα?2b inhibited the Hepcidin mRNA in HepG2 cells and LO2 cells. pSTAT3 was significantly decreased with the increased levels of IFNα?2b(P<0.05),and the expression of IL?6 and STAT3 had no significant changes with the increase of IFNα?2b. Conclusion The serum Hepcidin levels can be decreased because IFNα?2b suppresses the expression of Hepcidin,and its mechanism may be related with inhibited STAT3 pathway activation.
