Objective: To evaluate the effectiveness of a family-school collaborative intervention on sleep health among fifth-grade primary school students, so as to provide scientific evidence for promoting sleep health among primary school students. Methods: From April to June 2024, a baseline survey was conducted on 342 fifth-grade students and their parents from one primary school in a district of Beijing, using the convenient sampling method. A semester of sleep health education was implemented from September to December 2024, covering cognitive, behavioral and environmental factors that affected timely bedtime; and the program took various forms, including student courses, popular-science articles for parents, and personalized feedback reports. Another primary school in the same area was conveniently selected as the control group, where 313 fifth-grade students and their parents received routine health education. The subjects were assessed for their baseline and end-point (March to June 2025) sleep conditions using sleep diaries (222 participants in the intervention group and 225 in the control group) and accelerometers (120 participants in the intervention group and 88 in the control group), respectively. The independent samples t-test and the Wilcoxon rank-sum test were used to compare characteristics between groups，and linear mixed models were employed to evaluate the intervention effects. Results: In the sleep diary evaluation, the intervention group had an earlier weekend wake up time and a smaller social jetlag than the control group at baseline ( t/Z =3.42, 7.21); in the accelerometer evaluation, the intervention group exhibited a smaller social jetlag than the control group at baseline ( Z =3.90) (all P <0.05). In the sleep diary evaluation, compared with the control group, the intervention group showed a reduced pre-to-post change in school-day bedtime ( β = -6.70), whereas the pre-to-post changes in school-day sleep duration, weekend wake-up time, weekend sleep duration, and average sleep duration were all increased at baseline and at the end ( β =8.41, 22.58, 27.03,13.74) (all P <0.05). In the accelerometer evaluation, compared with the control group, the intervention group showed reduced pre-to-post changes in school-day sleep onset time and school-day wake time ( β =-14.75, -6.24), whereas the pre-to-post change in school-day sleep duration increased at baseline and at the end ( β =8.01) (all P <0.05). Conclusion A family-school collaborative sleep health intervention may be an effective strategy for improving sleep among fifth-grade primary school students.

Objective:To explore the impact of the two-way referral model on compliance and prognosis in patients with heart failure.Methods:This bidirectional cohort study enrolled chronic heart failure (CHF) patients treated at Qilu Hospital of Shandong University or designated primary hospitals between March 2018 and March 2022. Patients were categorized into two groups based on referral status: two-way referral group (participating in the referral model with≥1 follow-up visit at primary hospitals) and the core hospital group (receiving treatment and follow-up exclusively at Qilu Hospital). Baseline clinical characteristics were collected and compared between groups. Patients underwent followed-up, with primary endpoints including follow-up rate, drug (β-blockers, angiotension converting enzyme inhibitor (ACEI)/angiotensin Ⅱ receptor blockers (ARB)/angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter 2 inhibitors and mineralocorticoid receptor antagonists) utilization rate and target dose achievement rate. Secondary endpoints encompassed changes from baseline in left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDd), and N-terminal pro-brain natriuretic peptide (NT-proBNP), plus cardiovascular mortality and heart failure rehospitalization. Generalized linear mixed models analyzed longitudinal trends in LVEF, LVEDd, and NT-proBNP levels. Kaplan-Meier curves and Cox regression evaluated LVEF recovery rates, supplemented by subgroup analyses. Multivariate logistic regression was used to identify factors influencing target dose achievement rate for β-blockers and ACEI/ARB/ARNI therapies in CHF patients.Results:A total of 357 patients were enrolled, aged 53 (41, 63) years, including 256 males (71.7%). 157 patients were in the two-way referral group and 200 patients in the core hospital-treated group. Compared with the core hospital-treated group, the two-way referral group had lower baseline LVEF (28 (22, 34)% vs. 31 (23, 36)%, P=0.021) and systolic blood pressure (116 (104, 125) mmHg vs. 121 (109, 134) mmHg (1 mmHg=0.133 kPa), P=0.010). The 12-month follow-up rate of the two-way referral group was higher than the core hospital-treated group (73.8% vs. 56.0%, P=0.004). No significant between-group differences were observed in drug utilization rate of β-blockers, ACEI/ARB/ARNI, or sodium-glucose cotransporter 2 inhibitors during follow-up (all P>0.05), while mineralocorticoid receptor antagonists use showed a declining trend in both groups. Although the core hospital-treated group had higher target dose achievement rates for β-blockers (65.4% vs. 49.3%, P=0.042) and ACEI/ARB/ARNI (79.8% vs. 65.8%, P=0.046) than the two-way referral group, multivariate logistic regression indicated that the two-way referral model was not a negative predictor for these outcomes (all P>0.05). Both groups showed improved NT-proBNP, LVEDd, and LVEF from baseline (all P<0.001) with no significant difference in trends between groups (all P>0.05). There was no significant difference in the composite incidence (7.6% vs. 6.5%, P=0.674) and cumulative incidence (log-rank P=0.684) of cardiovascular death and heart failure rehospitalization at 12 months between two groups. Conclusion:The two-way referral model demonstrates advantages in improving medication adherence, drug utilization rates, and targetdoseachievement rates among CHF patients. This model not only promotes cardiac functional recovery but also reduces risks of cardiovascular mortality and heart failure rehospitalization, achieving comparable therapeutic and management outcomes to those observed in core hospital-treated patients.

Objective:To investigate the clinicopathological characteristics of lung transplantation and post-transplantation changes in patients with pneumoconiosis.Methods:A retrospective study was conducted to analyze the clinical and pathological data of 28 patients with pulmonary silicosis who underwent lung transplantation and were managed at the Department of Internal Medicine, Henan Provincial People′s Hospital, Zhengzhou, China from January 2015 to December 2024. Among them, 8 patients underwent lung biopsy 6-20 months after transplantation to evaluate the histopathological changes of the recipient and the donor lungs post-transplantation. The expression of relevant indicators was examined using immunohistochemical EnVision staining, while presence of microorganisms was assessed using histochemical special staining. The patients were all followed up.Results:Among the 28 patients with pneumoconiosis who underwent lung transplantation, 26 were male and 2 were female, with a male-to-female ratio of 13∶1. Their ages ranged from 23 to 68 years, median 50.0 (46.0, 53.5) years. They were diagnosed with pneumoconiosis at local occupational disease prevention and control centers for 3 to 15 years (mean, 9.65 years), including 13 left single lung transplants and 15 right single lung transplants. Gross examination showed fleshy nodules with irregular cystic cavities at the periphery. The cut surfaces exhibited gray-brown color and firm texture. Microscopically, most alveolar structures of the lung were obliterated, with nodular or diffuse proliferation of collagen fibers accompanied by hyaline degeneration. Focal massive carbon dust deposition and massive silicotic fibrosis were observed, surrounded by lung parenchyma with emphysematous changes and localized bullae formation. Seven patients underwent re-biopsy after transplantation that showed extensive infiltration of inflammatory cells. In 4 cases, microscopy revealed complete coagulative necrosis, with negative acid-fast staining and TB-DNA results. Of the 4 cases, 3 cases exhibited Aspergillus infection confirmed by Grocott′s methenamine silver and PAS stains, while 2 cases showed chronic bronchitis with squamous metaplasia. Follow-up revealed that 8 patients died of acute respiratory failure due to severe infection, while the remaining 20 demonstrated significant postoperative improvement in lung function.Conclusions:For patients with advanced pulmonary dust deposition disease who undergo lung transplantation, it is necessary to conduct standardized sampling and pathological assessment of the recipient lungs. In the early post-transplant period, the complications of re-biopsy tissues are mainly fungal infections. The combination of morphological manifestations and immunohistochemical detection is helpful to distinguish infection from rejection reactions. At the same time, it is essential to integrate clinical information and laboratory results to provide post-transplantation pathological assessment for individualized treatment.

Objective:To observe the short-term and medium-term clinical effects of electroacupuncture(EA)on patients with lumbar disc herniation(LDH)and to explore the cerebral effects based on resting-state functional magnet-ic resonance(rs-fMRI).Method:Thirty patients with LDH received EA at bilateral L3—S1 jiaji(EX-B2)and Dachangshu(BL25)points in continuous-wave mode at 20Hz(intensity adjusted to patient tolerance),20 minutes per session,every other day for ten sessions.Thirty-three age-and sex-matched healthy volunteers served as controls.All patients underwent rs-fMRI scans before treatment;The LDH group was rescanned one month after completion of EA.The modified Oswestry disability index(ODI),mental health summary(MCS)and physical health summary(PCS)of the short form health survey(SF-36)were assessed in LDH group before treatment and one,three,and six months after treatment.Voxel-wise regional homogeneity(ReHo)and degree centrality(DC)in brain areas were computed to compare between the two groups at baseline and pre-and post-treatment in LDH group.Result:After EA,LDH patients experienced significant reductions in ODI scores at one,three,and six months compared with baseline(P<0.05).PCS score continued to significantly improve at 3 months and 1 month(P<0.05),and the efficacy was the best at 3 months.There was a downward trend in 6 months after treatment,but still remained above baseline(P=0.072).The MCS score also rose at one and three months(P<0.05)but declined by six months.Compared with the control group,LDH patients exhibited increased ReHo in the left anterior cingulate gyrus,elevated DC in bilateral thalami,and decreased DC in bilateral postcentral gyri.After EA treatment,the LDH group showed increased ReHo in bilateral precuneus and the right middle frontal gyrus,as well as increased DC in the left postcentral gyrus.Conclusion:Electroacupuncture improves the short-term and medium-term clinical outcomes in LDH patients,with maximal benefit at three months.The role of electroacupuncture in improving pain and mental health is related to the regulation of pain matrix,default mode brain network,and emotional cognitive control network.

Objective:To investigate the preventive effect of a subanesthetic dose of esketamine on emergence agitation (EA) in pediatric patients undergoing fracture fixation surgery under general anesthesia.Methods:This study was a randomized, double-blind, placebo-controlled trial. Eighty-two pediatric patients, aged 3-6 yr, with American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, scheduled for elective closed reduction and internal fixation of humeral fractures at the People′s Hospital of Fuyang City from March 2023 to August 2024, were divided into 2 groups ( n=41 each) using simple random sampling: esketamine group (group E) and control group (group C). Group E received an intravenous injection of esketamine at a dose of 0.3 mg/kg before anesthesia induction, while the equal volume of normal saline was given instead in group C. The induction and maintenance of general anesthesia were the same in both groups. The drug was discontinued after operation and the children were transferred to the post-anesthesia care unit. The primary outcome was the occurrence of EA assessed using the Pediatric Anesthesia Emergence Delirium scale. Secondary outcome measures included the acceptance of the facemask during anesthesia induction, the rate of propofol use during the emergence period, the Children′s Hospital of Eastern Ontario Pain Scale scores at awakening and at 2 and 6 h postoperatively, the requirement for rescue analgesia in the emergence period, and the occurrence of adverse reactions. Results:Compared with group C, the incidence of EA [38% (15/39) vs. 15% (6/40)] was significantly decreased, the usage rate of propofol during the emergence period was decreased, the degree of acceptance of the facemask during anesthesia induction was increased, and Children′s Hospital of Eastern Ontario Pain Scale scores at all time points and the rate of rescue analgesia in the emergence period were decreased in group E ( P<0.05). There was no statistically significant difference in the incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:Administering a subanesthetic dose of esketamine before anesthesia induction can reduce the risk of EA in pediatric patients undergoing fracture fixation surgery under general anesthesia and raise the the quality of recovery with a high safety.

OBJECTIVE T o explore the long-term effect of multidimensional evidence-based interventions based on i-PARIHS theoretical framework on reduction of incidence of central line-associated bloodstream infections(CLABSI)in pediatric intensive care units(PICU)of pediatrics department and evaluate the impact on nurses'compliance to taking the interventions and use intensity of catheters.METHODS By means of quasi-experimental design,the multidimensional intervention system covering multidisciplinary collaboration,standardized operation procedures,information system optimization and hierarchical training was established and staged for implementa-tion of 5 years(from T0 baseline stage to T3 maintenance stage).The variations in implementation rates of cathe-ter maintenance(daily maintenance,dressings change,catheter removal)were analyzed by Chi-square test,and the change of incidence of CLABSI was monitored with the use of statistical process control U chart.RESULTS The nurses'compliance to operations was remarkably improved(P＜0.05)o The implementation rate of dressings change continuously increased from 52.91％in T0 to81.62％in T3(x2=72.444,P＜0.001),the implementa-tion rate of catheter removal increased from 48.72％to 79.31％(x2=8.179,P=0.042).The incidence rate of CLABSI decreased from 1.92％0 in 2019 to 0.5％0 in 2022,and the control chart showed that most of the months fluctuated within control limits.CONCLUSIONS The multidimensional evidence-based interventions can achieve a long term control of CLABSI by raising the nurses' compliance to operations.The information monitoring and closed-loop management are crucial to maintenance of the interventional effect,and the risk early warning system should be optimized with the combination of artificial intelligence technology.

Purpose To explore the diagnostic value of two-dimensional speckle tracking echocardiography(2D-STE)in differentiating left ventricular hypertrophy(LVH)caused by Fabry disease from other etiologies.Materials and Methods A total of 23 patients clinically confirmed Fabry disease with LVH(Fabry disease group)in Peking University First Hospital from August 2014 to February 2023,retrospectively.23 patients with hypertensive LVH(hypertensive LVH group)and 23 with hypertrophic cardiomyopathy(HCM)(HCM group)were also included.Conventional echocardiographic parameters and 2D-STE-derived left atrial strain and left ventricular longitudinal strain were analyzed and compared among the three groups.LASSO regression was used to select variables and construct a diagnostic model to differentiate hypertensive LVH,HCM and Fabry disease group.Results The Fabry disease group showed significantly reduced left ventricular global longitudinal strain and segmental left ventricular longitudinal strain in the basal anterior wall,basal anterolateral wall and mid inferior wall compared to the hypertensive LVH group(P<0.05).There were no significant differences in left atrial strain,left ventricular global longitudinal strain and segmental left ventricular longitudinal strain between the Fabry disease and HCM groups(P>0.05).Compared to the conventional echocardiography-based model,the combined model did not significantly improve diagnostic accuracy for differentiating the three etiologies(Z=-1.314--0.594,all P>0.05).Conclusion Compared to patients with hypertensive LVH,HCM and Fabry disease group exhibit varying degrees of decrease in global and segmental longitudinal strain of the left atrium and left ventricle.Additional measurements of left ventricular longitudinal strain and left atrial strain do not provide significant incremental diagnostic value over conventional echocardiography in distinguishing among Fabry disease,hypertensive LVH and HCM.

Objective·To identify and evaluate novel and reliable non-invasive serological biomarkers for detecting pancreatic ductal adenocarcinoma(PDAC).Methods·Sixty-seven PDAC patients(Ruijin cohort Ⅰ)were recruited at Pancreatic Center,Ruijin Hospital,Shanghai Jiao Tong University School of Medicine,from May 2018 to December 2019.Global proteome profiling of 67 PDAC tumor tissues and 67 matched adjacent normal tissues was performed using mass spectrum.Bioinformatics analysis on the proteomics data was conducted to identify new biomarkers,and receiver operating characteristic(ROC)curves and the area under the curve(AUC)were used to evaluate their value of detecting PDAC.The proteomic and mRNA sequencing data were further downloaded and analysed from the Clinical Proteomic Tumor Analysis Consortium(CPTAC)cohort for validation.In addition,the Ruijin Cohort Ⅱ,consisting of 47 PDAC patients and 75 healthy individuals,was recruited for a case-control study from June 2021 to June 2022.Enzyme-linked immunosorbent assay(ELISA)was used to detect the expression level of new biomarkers in the serum of patients and healthy individuals to evaluate the serological diagnostic values of them.Results·Collagen type Ⅻ α1 chain(COL12A1)was identified as a candidate biomarker for PDAC diagnosis based on differential expression analysis on the proteomic data and was validated to be higher in tumor tissues than in adjacent normal tissues in the CPTAC cohort.In addition,COL12A1 protein levels were significantly higher in the sera of PDAC patients than in those of healthy controls,showing good diagnostic performance with an AUC of 0.82,a sensitivity of 81%,and a specificity of 83%.ROC analysis revealed that COL12A1 improved the performance of carbohydrate antigen 199(CA199)in distinguishing PDAC patients from healthy individuals(AUCCA199=0.91 vs AUCCA199+COL12A1=0.95,P<0.05).Furthermore,COL12A1 also showed excellent ability to distinguish early-stage PDAC patients(stage Ⅰ?Ⅱ)from healthy individuals(AUCCOL12A1=0.83),and significantly improved the AUC of CA199 in early-stage PDAC patients(AUCCA199=0.92 vs AUCCA199+COL12A1=0.97,P<0.05).Conclusion·COL12A1 is a potential serological diagnostic marker that complements CA199 in detecting early-stage PDAC.

Objective To explore the effect of a health behaviour intervention program based on health action process approach(HAPA)on patients after implantation of a pacemaker.Methods Convenience sampling was conducted to select 154 patients who had implantation of a pacemaker in our hospital as research subjects.A random table was used to divide the patients into a control group and an trial group,with 77 patients per group.Patients in the control group were treated with conventional care and issued with exercise brochures,while the patients in the trial group were treated with conventional care with a HAPA-based health behaviour intervention program for 3 months.Both groups were evaluated using the rehabilitation exercise adherence questionnaire and the adult health self-management ability assessment scale before the intervention,at 3 and 6 months after the intervention.Cardiopulmonary function of the patients in both groups was assessed by 6-minute walk test.Results After 3 months and 6 months of intervention,the scores of rehabilitation exercise compliance and self-management ability of the patients in the trial group were better than those in the control group.The difference between the two groups was statistically significant(P<0.05).Six months after discharge,the 6-minute walking distance(6MWD)of the patients in the trial group was longer than that of the control group,and the difference between the two groups was statistically significant(P<0.05).Conclusion The health behaviour intervention program based on the HAPA enhances the exercise compliance in patients who were implanted with a pacemaker,as well as improves the self-management behaviour and cardiopulmonary function.
