Objective: To investigate the association between emotional intelligence and sleep problems at the symptom level among junior and senior high school students, so as to provide new insights for interventions targeting junior and senior high school students sleep disorders. Methods: From November 2023 to May 2024, a stratified cluster random sampling method was employed to select 3 531 first year junior high school and first year senior high school students from 6 schools in Guangyuan City and Liangshan Yi Autonomous Prefecture in Sichuan Province, as well as Lhasa City in Tibet Autonomous Region. The Insomnia Severity Index Scale and the Wong and Law Emotional Intelligence Scale(WLEIS) were used to assess sleep problems and emotional intelligence. A network analysis was performed to explore the relationship between emotional intelligence and sleep disorders, and a gender based network comparison analysis was conducted. Results: The reported rate of sleep problems among junior and senior high school students was 47.3%, with severe sleep problems of 2.2%. Difficulty maintaining sleep, worry about sleep, and emotional application were the core symptoms in the network (node strength values: 1.11, 0.98, and 0.82, respectively). Dissatisfaction with sleep and emotional application served as bridge symptoms connecting emotional intelligence and sleep problems (bridge strength values: 1.77 and 1.59, respectively). The edge weights of the emotional intelligence and sleep problems network differed significantly between genders (maximum difference in edge weight values was 0.13， P <0.05). Conclusions Emotional application ability and dissatisfaction with sleep are the key nodes in the network connecting emotional intelligence and sleep problems. Targeted efforts to enhance emotional application ability may effectively reduce the risk of sleep problems among junior and senior high school students.

Objective To analyze the willingness and influencing factors of doctors in Beijing public hospitals to set up clinics in the community,and to provide scientific basis for promoting quality health technicians to go down to the grassroots and realize hierarchical diagnosis and treatment.Methods Doctors from 6 specialized hospita ls and 3 general hospitals in Beijing were selected as subjects for questionnaire survey.By stratified sampling,a questionnaire survey was conducted on 518 doctors from 9 public hospitals in Beijing through stratified sampling method.Descriptive analysis,rank sum test and ordered logistic regression were used to explore doctors'willingness to open clinics and its influencing factors.Results In all survey respondents,212(40.93%)physicians were very or somewhat willing to open a clinic in the community,physicians with higher benefit perception,and greater willingness to publicize relevant policies were more willing to set up clinics.Conclusion Opening of clinics by doctors in public hospitals is affected by perceived benefits and willingness to advocate policies.It is suggested to further improve relevant systems and policies,reduce the risk of doctors opening clinics,and promote doctors in public hospitals to open clinics in communities,so as to realize the sinking of high-quality health human resources to the grassroots.

Objective To determine the pathogenicity of a novel mutation(c.109_111del)in DKC1 gene of an adult patient,and to analyze the clinical phenotype,immunophenotype and telomere length,so as to provide clues for early clinical identification and diagnosis.Methods The clinical data and peripheral blood samples of the patient were collected for genetic testing and family analysis.The lymphocyte subsets of the patient were detected by Flow cytometry,and the telomere length of the patient and healthy controls were detected by Flow-FISH.Results The main clinical manifestations of the patient were mucocutaneous triad,bone marrow failure and infection.The telomere length of lymphocytes in the patient was significantly shorter than that of healthy controls of the same age,and the absolute value and percentage of lymphocyte subsets were abnormal.Conclusion The clinical manifestations of DC patients are diverse.Flow-FISH detection of telomere length is helpful for early diagnosis of DC patients.

Objective To compare the dosimetric disparities among static intensity-modulated radiotherapy(IMRT),volumetric modulated arc therapy(VMAT),and tomotherapy(TOMO)techniques in cervical cancer radiotherapy for providing data support for clinical decision-making scheme of radiotherapy.Methods The clinical data of 19 cervical cancer patients,treated at the Affiliated Cancer Hospital and Institute of Guangzhou Medical University from February to May in 2024,were analyzed.Three plans were devised for each case using IMRT,VMAT,and TOMO techniques,followed by dosimetric evaluation in terms of various metrics such as dose volume parameters of the target areas as well as organs-at-risk(OAR),conformity index(CI),homogeneity index(HI),and delivery time.Results All 3 plans met the clinical prescription requirements for the target areas.Compared with static IMRT and VMAT,TOMO had significantly lower Dmean and Dmaxof PCTV and PGTVnd.For OAR,TOMO demonstrated significant advantages over IMRT and VMAT in the Dmean of the bladder,the Dmean,Dmax,V30,V40of the rectum,the Dmean,Dmax,V20,V30of left and right femoral heads,and the Dmean,V20,V50of the pelvis(P<0.05).In addition,the TOMO group showed significantly higher CI for both PCTV and PGTVnd as compared with IMRT and VMAT groups,and lower PGTVnd HI than IMRT group(all P<0.05).Although there was trivial difference among 3 groups in term of PCTV HI,TOMO group performed slightly better than the other two groups.Notably,VMAT technique had the shortest treatment time.Conclusion In various treatment modalities for cervical cancer,TOMO is superior to IMRT and VMAT in terms of target dose coverage,OAR dose distribution,CI,and HI.However,VMAT has the highest efficiency.

Pharmacological perturbation studies based on protein-level signatures are fundamental for drug dis-covery.In the present study,we used a mass spectrometry(MS)-based proteomic platform to profile the whole proteome of the breast cancer MCF7 cell line under stress induced by 78 bioactive compounds.The integrated analysis of perturbed signal abundance revealed the connectivity between phenotypic behaviors and molecular features in cancer cells.Our data showed functional relevance in exploring the novel pharmacological activity of phenolic xanthohumol,as well as the noncanonical targets of clinically approved tamoxifen,lovastatin,and their derivatives.Furthermore,the rational design of synergistic inhibition using a combination of histone methyltransferase and topoisomerase was identified based on their complementary drug fingerprints.This study provides rich resources for the proteomic landscape of drug responses for precision therapeutic medicine.

Background: The role of apurinic/apyrimidinic endonuclease 1/redox factor-1 (APE1/Ref-1) in adipose tissue remains poorly understood. This study investigates adipose tissue dysfunction in heterozygous APE1/Ref-1 deficiency (APE1/Ref-1+/-) mice, focusing on changes in adipocyte physiology, oxidative stress, adipokine regulation, and adipose tissue distribution. Methods: APE1/Ref-1 mRNA and protein levels in white adipose tissue (WAT) were measured in APE1/Ref-1+/- mice, compared to their wild-type (APE1/Ref-1+/+) controls. Oxidative stress was assessed by evaluating reactive oxygen species (ROS) levels. Histological and immunohistochemical analyses were conducted to observe adipocyte size and macrophage infiltration of WAT. Adipokine expression was measured, and micro-magnetic resonance imaging (MRI) was used to quantify abdominal fat volumes. Results: APE1/Ref-1+/- mice exhibited significant reductions in APE1/Ref-1 mRNA and protein levels in WAT and liver tissue. These mice also showed elevated ROS levels, suggesting a regulatory role for APE1/Ref-1 in oxidative stress in WAT and liver. Histological and immunohistochemical analyses revealed hypertrophic adipocytes and macrophage infiltration in WAT, while Oil Red O staining demonstrated enhanced ectopic fat deposition in the liver of APE1/Ref-1+/- mice. These mice also displayed altered adipokine expression, with decreased adiponectin and increased leptin levels in the WAT, along with corresponding alterations in plasma levels. Despite no significant changes in overall body weight, microMRI assessments demonstrated a significant increase in visceral and subcutaneous abdominal fat volumes in APE1/Ref-1+/- mice. Conclusion APE1/Ref-1 is crucial in adipokine regulation and mitigating oxidative stress. These findings suggest its involvement in adipose tissue dysfunction, highlighting its potential impact on abdominal fat distribution and its implications for obesity and oxidative stress-related conditions.
