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.

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.

Since the concept of patient versions of guidelines （PVGs） was introduced into China， several PVGs have been published in China， but we found that there is a big difference between the concept of PVG at home and abroad， and the reason for this difference has not been reasonably explained， which has led to ambiguity and even misapplication of the PVG concept by guideline developers. By analyzing the background and purpose of PVGs， and the understanding of the PVG concept by domestic scholars， we proposed the term patient guidelines （PGs）. This refers to guidelines developed under the principles of evidence-based medicine， centered on health issues that concern patients， and based on the best available evidence， intended for patient use. Except for the general attribute of providing information or education， which is typical of common health education materials， PGs also provide recommendations and assist in decision-making， so PGs include both the patient versions of guidelines （PVG） as defined by the Guidelines International Network （GIN） and "patient-directed guidelines"， i.e. clinical practice guidelines resulting from the adaptation or reformulation of recommendations through clinical practice guidelines.

OBJECTIVE To explore the self precipitation source of Erhuang powder, determine the content of related components and its efficacy on HeLa cells. METHODS Bifurcation study to identify the main compatibility of precipitating. The self precipitation, supernatant and extract of Erhuang powder were analyzed by UHPLC-Q-Exactive MS. The main compounds in Coptidis Rhizoma and Catechu, catechin, epicatechin, epicberberine, coptisine, berberine and palmatine were selected as controls. A analysis method of UHPLC for self precipitation, supernatant and extract of Erhuang powder was established and the related components were quantitatively determined. The effects of self precipitation, supernatant and extract on HeLa cells were evaluated by MTT method and flow cytometry. RESULTS A slight flocculation precipitate appeared when the decoction of Erhuang powder was mixed in pairs, while a large amount of flocculation appeared when the decoction of Coptidis Rhizoma and Catechu water was mixed. The self precipitation, supernatant and extract samples contained 39 compounds, which were mainly alkaloids and phenolic acids. The contents of catechin and berberine in the 6 index components were mostly, which accounted for 73.56% of the total content of the index components in self precipitation and 61.89% of the total content of the index components in extract. Inhibition effect on HeLa cells: extract ≈ self precipitation > supernatant, and inducing apoptosis: self precipitate ≈ extract, supernatant had no apoptosis-inducing effect. CONCLUSION Coptidis Rhizoma-Catechu is the main compatible formula for precipitation formation. The self precipitation and extracts of Erhuang powder are mainly alkaloids and phenolic acids, among which berberine and catechin are high in content and can be used as representative components. The effect of self-precipitation and extract on HeLa cells was better than that of supernatant. This basically indicates that the self precipitation components and pharmacological effects of Erhuang powder are similar to those of the extract.

Objective:To investigate the conversion of stromal vascular fraction (SVF) in the microenvironment of radiation-induced skin injuries to provide guidance for clinical applications.Methods:Based on a random number table, C57BL/6N mice were categorized into four groups: the blank control, negative control, acute injury, and chronic injury groups, with each group containing 25 mice. The backs of mice in the blank control, acute injury, and chronic injury groups were exposed to 15 Gy X-ray irradiation. Then, the mice in the negative control, acute injury, and chronic injury groups were injected subcutaneously with the SVF derived from B6/G-R mice. The survival of these mice was observed 1, 3, 7, 14, and 21 d after the injection through fluorescence tracing and in vivo imaging. Accordingly, the clinical SVF injection regimens were optimized based on the experimental result of mice. Finally, local SVF injection was performed on different frequencies for patients in different wound conditions, with the efficacy being observed. Results:The fluorescence of SVF was observed from the tissue slices of the acute injury, chronic injury, and negative control groups 14 d post-injection. The result showed that the fluorescence intensity of SVF 1, 3, and 7 d post-injection was in the order of the negative control group > the acute injury group > the chronic injury group. The acute injury group ranked at the top and the chronic injury group remained at the bottom 14 d after the injection. The fluorescence of SVF in each group was barely detected 21 d after the injection. Compared to the negative control group, the acute injury group exhibited statistical differences only 14 d post-injection ( t = 4.11, P < 0.05), while the chronic injury group displayed statistical differences 1, 3, 7, and 14 d after the injection ( t = 3.88-5.74, P < 0.05). Furthermore, the acute injury group exhibited significantly higher fluorescence intensity of SVF than the chronic injury group ( t = 4.73-8.38, P < 0.05). The half-life of SVF for the negative control, acute injury, and chronic injury groups was 6.336, 6.014, and 2.163 d, respectively. As indicated by the application of SVF transplantation based on traditional surgical protocols in the clinical trial, SVF can significantly promote wound repair, with earlier SVF transplantation being more beneficial for wound healing. Conclusions:The conversion of SVF differs in the microenvironments of acute and chronic radiation-induced skin injuries. This can serve as an essential guide for the administration timing and injection frequency of SVF in clinical applications.

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.

Objective:To analysis the incentive level of family doctors in primary medical and health institutions in Beijing, and to explore its influencing factors, so as to provide references for promoting family doctors′ contract service.Methods:From October to December 2021, 40 family doctors were randomly selected from 135 urban community health service centers in 8 districts of Beijing, and a survey was conducted on basic demographic information, institutional organizational capacity evaluation, and family doctor incentive level evaluation (including four dimensions of work value, organizational environment, personal development, and reward compensation), and the influencing factors of family doctor incentive level was analyzed. Chi-square test and Pearson correlation analysis were used for univariate analysis, and multiple linear regression analysis was used for multivariate analysis.Results:A total of 4 568 family doctors were included, and the score of family doctors′ incentive level was 3.75±0.81, among which the work value score was the highest(3.89±0.77), followed by the organizational environment score(3.69±0.92) and personal development score(3.75±0.90), and the lowest score was reward(3.75±0.90). Age, education, professional title, working years and average total working hours per week negatively affected the incentive level( P<0.05), while the average monthly income, the frequency of attending training and further study, and the organizational ability of the organization positively affected the incentive level( P<0.05). Conclusions:The overall incentive level of family doctors in primary medical and health institutions in Beijing needed improvement, and there were many factors that affect the incentive level of family doctors. It was recommended to appropriately increase the salary and benefits of family doctors, reasonably arrange the workload of family doctors, strengthen the training mechanism of family doctors, and strengthen the organizational capacity building of primary medical and health institutions.
