Objective: To investigate the current status of screening myopia and anxiety symptoms and associated factors among junior and senior high school students in Beijing, so as to provide evidence for myopia prevention and control and the improvement of mental health among adolescents. Methods: From September to November 2024, a total of 17 245 junior high schools, general senior high schools and vocational high schools from 16 districts in Beijing were enrolled by stratified cluster sampling method. Questionnaire surveys and vision screening were conducted to collect data on anxiety symptom and screening diagnosed myopia. The Chi square test was used to analyze the co-occurrence of myopia and anxiety symptoms, and binary Logistic regression analysis was adopted to explore the related factors of the co-occurrence. Results: The overall detection rate of cooccurrence screening myopia and anxiety symptoms among Beijing junior and senior high school students was 6.00%. The detection rate was higher in females ( 7.15 %) than in males (4.90%), higher in urban areas (6.65%) than in suburban areas (5.41%), and higher in general senior high school students (7.61%) than in vocational high school students (6.46%) and junior high school students (4.65%). All differences were statistically significant ( χ 2=38.49, 11.66, 54.88, all P <0.01). Binary Logistic regression analysis showed that female gender ( OR =1.43), general senior high school ( OR =1.60), vocational high school ( OR =1.59), daily sugar sweetened beverage intake ( OR =1.66), participation in academic extracurricular classes in preschool ( OR =1.30), electronic screen use for more than 2 hours per day ( OR =1.21), and insufficient sleep ( OR =2.41) were associated with an increased risk of co-occurring screening diagnosed myopia and anxiety symptoms (all P <0.05). Conclusions The co-occurrence of screening diagnosed of myopia and anxiety symptoms among junior and senior high school students in Beijing is common. Female gender, senior high school students, and unhealthy lifestyle behaviors are all risk factors for the co-occurrence of myopia and anxiety symptom. Comprehensive intervention measures can be adopted to simultaneously promote vision protection and mental health among junior and senior high school students.

Objective: To study the correlation between short sleep duration and screening myopia among primary and middle school students in Beijing, so as to provide a scientific basis for the comprehensive prevention and control of myopia among students. Methods: Using a stratified cluster random sampling, 25 593 primary and middle school students from 16 districts of Beijing were selected from September to November 2023. The National Common Diseases and Health Influencing Factors Monitoring Survey Questionnaire was used to conduct a questionnaire survey, and visual acuity was tested according to the Specification for the Screening of Refractive Error in Primary and Middle School Students. The reporting rates of short sleep duration and detection rates of screening myopia among primary and middle school students were compared using the Chi square test. Binary Logistic regression was used to analyze the correlation between short sleep duration and screening myopia. Results: About 68.63% of students reported short sleep duration. There was a statistically significant difference in the reporting rate of short sleep duration among students in different school stages ( χ 2=981.18, P <0.01), with the lowest reporting rate of vocational high school students (47.07%) and the highest reporting rate of ordinary high school students (76.17%). The detection rates of screening myopia among primary school students ( 57.09% ) and middle school students (76.53%) who reported short sleep duration were higher than those who reported enough sleep duration (52.65%, 71.94%), with satistically significant differences ( χ 2=14.83, 17.96, P <0.01). The results of binary Logistic regression analysis showed that primary and middle school students with short sleep duration had a higher risk of developing screening myopia, compared to students with enough sleep duration ( OR =1.25); after adjusting for confounding factors such as educational stage, gender, region, boarding situation, primary and secondary school students with short sleep duration still had a higher risk of screening myopia ( OR =1.26) ( P <0.01). The analysis results stratified by educational stage showed that primary school students from grades 4-6 and middle school students with short sleep duration had a higher risk of screening myopia ( OR=1.18, 1.20, P <0.01). Conclusions Primary and secondary school students in Beijing with short sleep duration sleep have a higher risk of developing screening myopia. Families, schools, and society should ensure enough sleep duration to reduce the occurrence of myopia among students.

Postnatal glucocorticoid has become an important measure for the prevention and treatment of bronchopulmonary dysplasia in preterm infants. Systemic application of glucocorticoids has therapeutical effectiveness but comes with significant side effects. Many studies have shown that nebulized budesonide may help prevent and treat bronchopulmonary dysplasia in preterm infants. However, there are no clear recommendations on the timing, route, dosage, and short- or long-term efficacy. Therefore, this paper reviews the research progress on the application of nebulized budesonide for the prevention and treatment of bronchopulmonary dysplasia in preterm infants.

AIM:This study aims to investigate the mechanism by which LINC00973 regulates multidrug re-sistance of non-small-cell lung cancer(NSCLC).METHODS:The GEPIA database was employed to analyze the expres-sion levels of LINC00973 in NSCLC and its correlation with patient prognosis in clinical settings.RT-qPCR was utilized to assess LINC00973 expression in various NSCLC cell lines and chemoresistant cells.The migration,invasion,stemness ca-pacity,and drug sensitivity of NSCLC cells with either overexpression or knockdown of LINC00973 were evaluated using wound healing assay,Transwell assay,sphere formation assay,and CCK-8 assay.RNA sequencing was conducted on LINC00973-overexpressing and parental NSCLC cells to identify dysregulated pathways and targets.The LncBase Pre-dicted v.2 and TargetScan databases were used to predict the microRNAs(miRNAs)co-bound by LINC00973 and their target genes.Mimics and inhibitors of candidate miRNAs were synthesized and transfected into NSCLC cells subjected to LINC00973 overexpression or knockdown.Changes in the expression level of LINC00973,and the mRNA and protein ex-pression levels of its target genes were assessed using RT-qPCR and Western blot.RESULTS:Analysis of the GEPIA da-tabase revealed that LINC00973 was significantly up-regulated in lung adenocarcinoma and lung squamous cell carcino-ma,correlating with poor prognosis of NSCLC patients.The LINC00973 expression was elevated in various NSCLC and chemoresistant cell lines(A549/DDP and A549/5-FU).Overexpression of LINC00973 in A549 and H520 cells markedly enhanced their migration,invasion,and stemness capabilities,while concurrently reducing sensitivity to chemotherapy and targeted therapies.RNA sequencing,along with RT-qPCR results,indicated that ATP-binding cassette transporter G5(ABCG5)was activated in LINC00973-overexpressing A549 and H520 cells.Further database analyses and dual trans-fection experiments confirmed that LINC00973 regulated ABCG5 expression through competitive binding with hsa-miR-150-5p.CONCLUSION:LINC00973,which is aberrantly up-regulated in NSCLC specimens and associated with poor clinical prognosis,promotes the expression of ABCG5 through competitive binding with hsa-miR-150-5p.This interaction leads to en-hanced invasion,stemness,and multidrug resistance in NSCLC cells.

Objective:To identify the risk factors of venous thromboembolism (VTE) in postoperative renal transplantation recipients by Meta-analysis, and to provide evidence-based reference for clinical staff to develop early VTE prevention strategies.Methods:PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, VIP database, Wanfang database and Chinese Biomedical Literature Database were searched to collect the studies on the risk factors of postoperative VTE in kidney transplant recipients. The search period was from the establishment of the database to March 10, 2024. After literature screening, data extraction and quality evaluation were conducted independently by two researchers, Meta-analysis was performed using RevMan 5.3 software.Results:A total of 15 literatures with 20 influencing factors were included. Meta-analysis showed that age ( MD = 6.36, 95% CI 2.56-10.17, P<0.05), body mass index ( MD = 1.83, 95% CI 0.15-3.50, P<0.05), VTE history ( OR = 2.04, 95% CI 1.08-3.86, P<0.05), blood transfusion history ( OR = 3.77, 95% CI 2.43-5.83, P<0.05), glomerular filtration rate ( MD = -5.54, 95% CI -9.93 - -0.91, P<0.05), donor age ( MD = 3.18, 95% CI 1.10-5.25, P<0.05), combination of malignant tumor ( OR = 2.87, 95% CI 1.45-5.68, P<0.05), end-stage renal disease as polycystic kidney disease ( OR = 1.76, 95% CI 1.39-2.22, P<0.05), and interstitial nephritis ( OR = 1.60, 95% CI 1.06-2.40, P<0.05) were the influencing factors for postoperative VTE in renal transplant recipients. Conclusions:Clinical medical staff should actively identify high-risk groups for VTE after kidney transplantation by considering the 8 influencing factors determined by this study, and take targeted measures early to reduce the risk of postoperative VTE.

Objective:To analyze the current status and trends of lung cancer incidence and mortality in China and selected global regions, providing evidence for lung cancer prevention strategies in China.Methods:We extracted data from the GLOBOCAN 2022 database. Age-standardized Incidence rate (ASIR) and Age-standardized Mortality rate (ASMR) were calculated using Segi's world standard population. Epidemiological patterns were analyzed by region, age, sex, and human development index (HDI). Simple linear regression and Spearman's rank correlation coefficient were used to examine associations between HDI and ASIR/ASMR.Results:In 2022, global lung cancer incidence and mortality reached 2.48 million and 1.82 million cases respectively, with age-standardized rates of 23.6 per 100 000 (ASIR) and 16.8 per 100 000 (ASMR). Gender disparities were prominent, with male ASIR and ASMR being 2.0-fold and 2.5-fold higher than females. Elderly populations showed 11.6-fold higher ASIR and 14.4-fold higher ASMR compared to working-age adults. HDI demonstrated strong positive correlations with both ASIR ( r=0.79, P＜0.001) and ASMR ( r=0.74, P＜0.001). China accounted for 1.06 million new cases and 0.73 million deaths, with ASIR (40.8 per 100 000) and ASMR (26.7 per 100 000) exceeding global averages by 1.7-fold and 1.6-fold respectively. Chinese males showed 1.7-fold higher ASIR and 2.7-fold higher ASMR than females. Trend analysis revealed persistently high male incidence in China whereas rapidly increasing female rates, narrowing gender disparities. Projections estimate 1.80 million incident cases and 1.41 million deaths by 2050, representing 69.3% and 92.0% increases from 2022 levels. Conclusions:Significant heterogeneity exists in lung cancer burden across demographics and development levels, with strong HDI correlations. China bears disproportionate disease burden, necessitating intensified prevention efforts. These findings underscore the urgency of targeted interventions in high-risk populations.

Primary small cell carcinoma of esophagus(PSCCE)is a rare and highly aggressive neuroendocrine tumor,accounting for 0.05%to 3.1%of all esophageal malignancies.Its biological characteristics are similar to those of small cell lung cancer,with highly aggressive behavior and early dissemination tendency.It often metasta-sizes rapidly through lymphatic and hematogenous pathways.The prognosis is extremely poor,with a 5-year overall survival rate of less than 15%.There are no large-scale randomized controlled trials,and no standard treatment strategies have been established.In recent years,the treatment of limited-stage PSCCE has become a focal point of research.In traditional treatment paradigms,endoscopic therapy is feasible for very early-stage cases,while radical surgery serves as the primary approach for relatively early-stage patients.For locally advanced cases,two predominant treatment modalities are commonly employed in clinical practice:a surgery-based comprehensive treatment regimen and a radical chemoradiotherapy-centered therapeutic protocol,with no definitive conclusion yet reached regarding the optimal treatment strategy.Concurrently,emerging therapeutic strategies such as immuno-therapy and molecularly targeted therapy have demonstrated remarkable clinical efficacy,thereby providing novel therapeutic opportunities for limited-stage PSCCE.This article aims to review the recent advances in the treatment of limited-stage PSCCE,summarize the current diagnostic and therapeutic landscape,and outline future directions in this field.

This study aims to screen the diagnostic biomarkers for fecal antigen of Echinococcus granulosus(E.granulosus)in dogs with high specificity and sensitivity.The sheep-derived EgPSC artificially infected dogs were collected,and the negative and positive fecal samples of dogs with E.granulosus were prepared by arecoline hydrobromide leakage method.Polyclonal antibody,negative fecal antigen-polyclonal antibody conjugates and positive fecal antigen-polyclonal antibody conju-gates were purified by ammonium sulfate precipitation and affinity chromatography,three groups of samples were detected by ELISA and Western blot,LC-MS/MS and bioinformatics analysis were performed on the three groups of samples.The positive fecal antigen-polyclonal antibody con-jugate was used as the treatment group,the polyclonal antibody and the negative fecal antigen-polyclonal antibody conjugates were used as the control groups to screen the unique peptides of the treatment group.ELISA and Western blot showed that only the positive fecal antigen-polyclonal antibody conjugates were positive.According to LC-MS/MS and bioinformatics analysis,11 unique peptides were screened out only in the treatment group.Among them,3 proteins were related to E.granulosus,namely dysferlin,integrator complex 9 and diagnostic antigen gp50,which were mem-brane-associated proteins,INT complex components and diagnostic antigens.This study has pre-liminarily screened out three candidate canine E.granulosus fecal antigen diagnostic markers,pro-viding a reference for further exploration of diagnostic standards for E.granulosus,screening of echinococcosis target genes,and vaccine development.
