Objective: To explore the relationship between life skills, psychological resilience and subjective well-being among primary and secondary school students, so as to provide evidence for targeted adolescent mental health education. Methods: From September to November, 2025, a total of 5 831 primary and secondary school students from five cities (Beijing, Guangzhou, Shenzhen, Chongqing, Urumqi) were selected by convenience sampling. The Adolescent Subjective Well being Scale, School based Adolescents Life Skills Scale, and Adolescent Psychological Resilience Scale were used for investigation. Data were analyzed using t-tests, one way ANOVA, and linear regression. Results: The total mean score of students subjective well being was (5.46± 0.91) ; the total mean score of life skills was (3.69±0.64); the total mean score of psychological resilience was (3.66±0.69). Statistically significant differences in subjective well being scores were found among students grouped by gender, grade, school stage, residential city, living with parents or living with siblings ( t/F =4.14, 53.92, 14.53, 49.99, 13.49, 2.18, all P <0.01). Stratified regression analyses were performed by gender (adjusting for school stage, residential city and living arrangement) and by school stage (adjusting for gender, residential city and living arrangement), the regression results indicated that life skills of boys, girls, primary school students and junior high school students( β =0.54, 0.53, 0.50, 0.57) and their psychological resilience ( β = 0.56 , 0.60, 0.56, 0.60) were positively associated with subjective well being (all P <0.01). Conclusions Life skills and psychological resilience may be important protective factors for subjective well being among primary and secondary school students. School based mental health education should emphasize life skills training and resilience building to promote students subjective well being.

Objective: To explore the association between parental subjective well-being and subjective well-being among primary and secondary school students, so as to provide evidence for promoting adolescent mental health from a family perspective. Methods: From September to November 2025, a convenience sampling method was used to recruit 4 612 students in grades 4-8 from 12 primary and secondary schools in five cities—Beijing, Guangzhou, Shenzhen, Chongqing, and Urumqi—along with their parents. Students completed the Adolescent Well being Survey Questionnaire, while parents completed the Parental Well being Survey Questionnaire. Data were analyzed using t-test, one way analysis of variance, multiple linear regression, Logistic regression, and stratified subgroup analyses. Results: The maximum score of the subjective well-being scale for primary and secondary school students was 301, with a total score of (224.07±46.63), representing 74.4% of the full score; the maximum score of the parental subjective well-being scale was 120, with a total score of (92.35±15.10), representing 77.0%. Multiple linear regression analysis showed that parental subjective well-being was positively associated with students overall subjective well-being, positive affect, and satisfaction in each domain (friendship, family, school, environment, freedom, and academics), and negatively associated with negative affect ( β =0.45, 0.08, 0.06, 0.07, 0.05, 0.04, 0.05, 0.04, -0.05, all P <0.01). Logistic regression and stratified analysis showed that parental subjective well-being was positively associated with students high subjective well-being ( OR =1.03), and the association existed in subgroups of different gender, grade and family structure ( OR =1.02-1.04) (all P <0.05). Conclusions Parental subjective well-being is positively associated with students subjective well-being. Future interventions should incorporate an integrated strategy featuring family-school collaboration to promote adolescent well-being.

Objective To explore the association between gut microbiota and liver cirrhosis in East Asian populations by using Mendelian randomization(MR)methods.Methods Genome wide association study(GWAS)datasets on gut microbiota were obtained from National GeneBank Big Data Platform and GWAS datasets on liver cirrhosis were obtained from IEU Open GWAS database,by using gut microbiota as the exposure factor and liver cirrhosis as the outcome variable.Inverse variance weighted(IVW)method was adopted as the main analytical method,with the constrained maximum likelihood and model averaging(cML-MA)method as a secondary analysis method,to verify the causal relationship between gut microbiota and liver cirrhosis.The robustness of the results were further validated through sensitivity analysis and leave-one-out analysis.Results The primary IVW analysis preliminarily identified 16 gut microbiota species associated with liver cirrhosis.An increased abundance of Clostridium L2-50,Marvinbryantia,Sulfate-reducing bacteria,Treponema socranskii,Coprococcus,Ruminococcaceae,Sanguinibacter,Vibrio funis,Thermanaerovibrio,and Mitsuokella was found to elevate the risk of liver cirrhosis.Conversely,an increased abundance of Desulfovibrio,Clostridium hathewayi,Propionibacterium,Allistipes,Bacteroides salanitiphilus,and Dyella was associated with a reduced risk of liver cirrhosis.The cML-MA analysis revealed statistical significance for Mitsuokella,Clostridium L2-50,Marvinbryantia,Coprococcus,and Dyella,indicating a strong correlation between these five gut microbiota species and liver cirrhosis.The heterogeneity and horizontal pleiotropy for 16 bacterial clusters showed P＞0.05,suggesting an absence of heterogeneity and horizontal pleiotropy,and the leave-one-out analysis did not identify any abnormal single nucleotide polymorphism.Conclusion This research reveals an association between 16 gut microbiota and liver cirrhosis in the East Asian population,with 5 of these gut microbiota demonstrating a significant correlation with liver cirrhosis,and offering new genetic insights for the prevention and treatment of liver cirrhosis.

Objective:To investigate the correlation of the expression of Ephrin A receptor 2(EphA2)and its promoter region DNA hypomethylation with the occurrence of pyroptosis in invasive breast cancer. Methods:The expression level of pyroptosis-related protein EphA2 in normal breast tissue,paracancerous tissues and cancer tissues from 42 breast cancer patients was examined by Immunofluorescence staining and Western blotting.The expression level of pyroptosis related protein nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)was analyzed by immunofluorescence staining and Western blotting.The expression levels of apoptosis related proteins Caspase 1 and inflammatory cytokine interleukin-1β(IL-1 β)were studied by Western blotting.The DNA methylation level in the promoter region of EphA2 was investigated by nested methylation-specific PCR(nMS-PCR).The expression levels of DNA methyltransferase 1(DNMT1)and DNA methyltransferase 3a(DNMT3a)were examined by Western blotting.The correlation of the protein expression and methylation level of EphA2 in cancer tissues with the expression NLRP3,Caspase 1,IL-1 β,DNMT1 and DNMT3a was analyzed by Pearson correlation coefficient. Results:Compared with normal breast tissues and paracancerous tissues,the expression level of EphA2 protein was significantly increased(P＜0.01),while that of NLRP3,Caspasel and IL-1 βwas significantly decreased(P＜0.05)in breast cancer tissues.Meanwhile,compared with normal breast tissues and paracancerous tissues,the DNA methylation level of EphA2 promoter in breast cancer tissues was significantly decreased(P＜0.05),the expression level DNMT3a protein was significantly decreased(P＜0.01,P＜0.05),and the difference in the expression level of DNMT1 protein was not statistically significant.Pearson correlation analysis showed that the expression level of EphA2 protein is negatively correlated with that of NLRP3(r=-0.651 2,P＜0.05),Caspasel(r=-0.571 2,P＜0.05),IL-1β(r=-0.654 6,P＜0.05)or DNMT3a(r=-0.537 4,P＜0.05),while the methylation level of EphA2 was positively correlated with the protein expression level of NLRP3(r=0.634 1,P=0.026 8),Caspase1(r=0.672 8,P=0.01 6 5),IL-1 β(r=0.694 0,P=0.01 2 3)and DNMT3a(r=0.687 1,P=0.01 3 6). Conclusion:The expression of EphA2 protein is upregulated in breast cancer tissues is negatively correlated with pyroptosis.DNMT3a may be involved in the process of DNA hypomethylation in the promoter region of EphA2.

Objective:To explore the influencing factors of all-cause death in patients with acute myocardial infarction (AMI) and renal insufficiency(RI), and establish a clinical prediction tool.Methods:Collected 727 patients who were hospitalized in Beijing Anzhen Hospital from January 1st 2014 to April 31th 2019, and diagnosed as AMI with RI. Recorded the patients' baseline characteristics, past medical history, current complications, laboratory and auxiliary examination results, treatment methods (included target vessel reconstruction methods, medications, etc.), and follow-up patients for all-cause deaths. Firstly, multivariate Cox regression analysis was used to construct the model in the training set(485 cases). Secondly, the receiver operating characteristic curve ( ROC), calibration curve and clinical decision curve analysis (DCA) were drawn in the validation set(242 cases) to further verify the effect of the prediction model. Finally, a nomogram was developed based on the verified risk factors. Results:Multivariate Cox regression analysis found that there were nine predictors for the prognosis of all-cause death in patients with AMI & RI, the dangerous factors included women, comorbidities, high direct bilirubin, cardiogenic shock, respiratory failure, co-infection and hemofiltration; the protective factors included PCI and taking aspirin. Model evaluation results showed that the AUC of the validation set was 0.82; the calibration line was close to the ideal calibration line, and the slope≈1, the intercept≈0, and the fitting effect was good. Clinical decision-making when the all-cause mortality rate was 35%, the net benefit of active intervention patients based on the Cox model was 38%. A visual nomogram model was developed based on the prognostic risk factors that have been evaluated and predicted to be good. Conclusion:Women, with a history of comorbidities, direct high bilirubin, combined with cardiogenic shock, combined with respiratory failure, combined infection, hemofiltration, PCI and taking aspirin, these nine factors will affect all causes of AMI & RI. For the probability of death, the model developed in this research has high accuracy.

Objective:To conduct a longitudinal study on different social support needs of patients with acute myocardial infarction (AMI) at different stages undergoing emergency PCI based on timing it right framework combined with multidimensional model of social support, so as to provide reference for the implementation of accurate nursing.Methods:Using the interpretative phenomenological research method, a total of 21 emergency PCI patients from Department of Cardiology in two ClassⅢ Grade A hospitals in Taiyuan were selected from December 2019 to July 2020 by the purposive sampling method. According to the course of the disease, 4 semi-structured interviews were conducted on the patients, combined with participatory observation. The interpretive phenomenological analysis method was used to analyze the data, and the social support multi-dimensional model was used to classify the results.Results:A total of 23 themes were extracted. The information support requirements of each phase were in order of diagnosis and risk, AMI and PCI related knowledge, medical notification rights, individualized paper discharge guidance, causes of discomfort and first aid knowledge (the latter two phases were the same) . The tool support requirements for each phase were emergency medical services, advanced stents and emergency PCI technology, green channels, economic support and mobile health care resources (the latter two phases were the same) . The emotional support needs of each stage included companionship and sense of security, acceptance and encouragement, psychological adjustment and construction (the same in the next phase) and strengthening independence. The social network support needs of each stage included the assistance of strangers to send to the hospital, the virtue and skill of medical staff, peer support, and reintegration into society (the latter three stages were the same) . The need for self-esteem support in each period was believing that they can survive, taking care of themselves as much as possible, keeping their illness confidential, receiving recognition for their recovery and giving back to others.Conclusions:The social support needs of emergency PCI patients change with the course of the disease. It is recommended that medical staff adopt a dynamic and continuous care concept, establish and improve a framework of social support needs that meets the local humanities, so as to facilitate education, evaluation and intervention.

Objective To observe the clinical effect of ultrasound-guided quadratus lumborum block combined with enhanced recovery after surgery (ERAS) for the laparoscopic appendectomy in children. Methods A total of 154 children undergoing laparoscopic appendectomy, 114 males and 40 females, aged 3-10 years, ASA physical status Ⅰ or Ⅱ, were divided into the ERAS group (group E) and control group (group C), n = 77 each group. Patients in group E received ultrasound-guided deep injection of 0.2％ ropivacaine 0.75 ml/kg into quadratus lumbar muscle. According to the guidelines for rapid rehabilitation fasting for 4 h and abstaining from drinking for 2 h, functional beverages were given 30 min before operation and parental escort during induction of anesthesia while given general anesthesia with laryngeal mask, that is, propofol 2-6 mg·kg-1·h-1 was continuously pumped with 2％-6％ sevoflurane. Patients in group C were given traditional anesthesia, strict fasting for 6 h and no drinking for 4 h, as while as induction with midazolam, propofol, atracurium and sufentanil and tracheal intubation. The VAS scores at 2, 3, 6 and 12 h post-operation were recorded. The awakening time, anal exhaust time, ambulation time, hospitalization days, the patient's satisfaction rates were recorded. The cases of nausea, vomiting, regurgitation and aspiration were recorded. Results The VAS scores at 2, 3, 6 and 12 h post-operation in group E were significantly lower than that in group C (P ＜ 0.05). All the postoperative rehabilitation indicators in group E were superior to group C, including the awakening time, anal exhaust time, ambulation time, hospitalization days and patient's satisfaction (P ＜ 0.05). Complication incidences in group E were significantly declined compared with group C (P ＜ 0.05). Conclusion For children undergoing laparoscopic appendectomy, ultrasound-guided quadratus lumborum block combined with the ERAS strategy could result in less postoperative complications, reduced postoperative pain, rapid rehabilitation, shortened hospitalization time and increased patients' satisfaction.

Objective To explore the effect of nursing intervention based on the transtheoretical model and stages of change on breastfeeding knowledge, self-efficacy, and duration of breastfeeding in newly born pregnant women, aimed to provide reference for breastfeeding behavior health education model for pregnant women. Methods The 130 primiparas who came to the hospital graded a class- three of Shanxi Province for perinatal examination were selected as the research subjects from May to June in 2017 , they were divided into test group and control group by random digits table method. In the control group, the normal breastfeeding health guidance was carried out in the three stages of prenatal, hospitalized and after discharge. The test group divided the primipara from the beginning of pregnancy to 6th months postpartum period into 5 stages according to transtheoretical model and stages of change. The new strategy of breastfeeding should be formulated and implemented according to different stages and behavior changing processes.
