Objective:To explore the application effect of the BOPPPS[bridge-in(B), objective(O), pre-assessment(P), participatory learning(P), post-assessment(P), Summary(S) ]model combined with scenario-based teaching in out-of-school first aid training for school-aged children, aiming to offer insights for relevant educational practices.Methods:A quasi-experimental study was conducted. Using cluster sampling, 131 school-aged children participating in Wuhan first aid summer camp from July to August 2024 were selected as participants. Among them, 65 children enrolled in July 2024 were assigned to the control group and received training using traditional teaching methods, while 66 children enrolled in August 2024 were assigned to the experimental group and underwent training designed with the BOPPPS model integrated with scenario-based teaching according to the time of entry into the camp. After the training, theoretical exam scores, learning process evaluations, and training satisfaction were compared between the two groups.Results:The control group included 31 boys and 34 girls, aged (9.32 ± 1.83) years; the experimental group included 34 boys and 32 girls, aged (9.71 ± 1.73) years. After the intervention, the total scores of theoretical examination, learning process evaluation, and training satisfaction in the experimental group were (90.27 ± 4.41), (42.79 ± 1.39), and (21.43 ± 2.41) points, respectively, which were higher than those in the control group (82.05 ± 6.29), (38.85 ± 1.91), and (19.54 ± 3.02) points, and the differences were statistically significant ( t=6.94, 3.15, 4.16, all P<0.05). Conclusions:This out-of-school first aid training for school-aged children leveraged the professional expertise of a tertiary grade A hospital′s pediatric department. The integration of the BOPPPS model with scenario-based teaching effectively enhanced the first aid competencies of school-aged children and improved their satisfaction with the training.

Objective:To analyze the expression level of protein arginine methyltransferase 5 (PRMT5) in pancreatic cancer tissues and its correlation with prognosis using bioinformatics methods, and to explore its potential mechanisms.Methods:Expression analysis of the PRMTs family members was performed based on the gene expression profiles of 178 pancreatic cancer tissues from the Gene Expression Profiling Interactive Analysis (GEPIA) database and 171 normal pancreatic tissues from the TCGA and GTEx databases. Using the median expression level of PRMTs family members in pancreatic cancer tissues as the cutoff, patients were divided into high-expression and low-expression groups, and Kaplan-Meier curves for overall survival (OS) and disease-free survival (DFS) were plotted. The correlation between PRMT5 expression and the expression of oncogenes such as KRAS, TP53, BRCA1, BRCA2, and SLC39A4 was analyzed. Functional enrichment analysis was conducted on genes similar to PRMT5, and a protein-protein interaction (PPI) network was constructed to analyze the interaction relationships among these similar genes. Pancreatic cancer PANC1 and AsPC-1 cells cultured in standard medium served as the control group, while PANC1 and AsPC-1 cells cultured in medium supplemented with the PRMT5 inhibitor EPZ015666 served as the intervention group. Cell viability was assessed using the CCK-8 assay, and cell cycle progression was analyzed by flow cytometry.Results:The expression level of PRMT5 in pancreatic cancer tissues was significantly higher than that in normal pancreatic tissues and showed a significant negative correlation with both OS and DFS. Patients with high PRMT5 expression had a shorter median survival time compared to those with low expression (17.2 months vs 19.5 months). PRMT5 expression was significantly positively correlated with the expression of oncogenes KRAS, TP53, BRCA1, BRCA2, SLC39A4, and KLF5. Genes similar to PRMT5 were primarily enriched in cell cycle-related signaling pathways, and NOP58 identified as a hub gene in the PPI network. Compared to the control group, the proliferation activity of PANC1 and AsPC-1 cells in the intervention group was significantly reduced [(67.3±1.9)% vs (100±4.4)% for PANC1; (60.5±2.7)% vs (100.0±1.7)% for AsPC-1], and the proportion of cells in the G1 phase was significantly increased [(51.6±0.7)% vs (35.3±2.7)% for PANC1; (51.2±0.9)% vs (29.7±2.2)% for AsPC-1]. All these differences were statistically significant (all P values <0.05). Conclusions:High expression of PRMT5 was closely associated with poor prognosis in pancreatic cancer patients, and it may contribute to pancreatic cancer progression by regulating the cell cycle.

Objective To investigate the expression levels of Ubiquitin Carboxy-Terminal Hydrolase-L1(UCH-L1)and Netrin-1 in the serum of patients with spontaneous basal ganglia hemorrhage(ICH)complicated with cerebral edema,and to analyze their impacts on neurological deficits and prognosis.Methods A retrospec-tive analysis was conducted on the clinical data of 173 patients with spontaneous basal ganglia hemorrhage admitted to the Department of Neurosurgery,The First Affiliated Hospital of Bengbu Medical University from September 2023 to January 2025.The serum levels of UCH-L1 and Netrin-1 were measured within 24 hours after the onset.They were divided into three groups according to the size of the cerebral edema volume(CEV):Group A(CEV<10 mL),Group B(CEV 10～30 mL),and Group C(CEV>30 mL).Pearson's correlation analysis was used to analyze the correlation between serum expression levels of UCH-L1 and Netrin-1 with hemorrhage,volume of cere-bral edema,distance of midline shift,Modified Edinburgh-Scandinavian Stroke Scale(MESSS)score,Modified Rankin Scale(mRS)score,and Glasgow Coma Scale(GCS)score.Logistic regression analysis was performed to identify the risk factors for poor prognosis.Receiver operating characteristic(ROC)curve analysis was used to evaluate the predictive value of UCH-L1 and netrin-1 for poor prognosis.Results Significant differences were observed in the serum levels of UCH-L1 and netrin-1 among patients with different volumes of cerebral edema(P<0.05).The larger the volume of cerebral edema,the higher the expression levels of UCH-L1 and netrin-1.The serum levels of UCH-L1 and Netrin-1 were significantly higher in the poor prognosis group compared to the good prognosis group(P<0.05).The serum levels of UCH-L1 and Netrin-1 were positively correlated with MESSS score,hemorrhage volume,cerebral edema volume,distance of midline shift,and mRS score(P<0.05),and negatively correlated with GCS score(P<0.05).Multivariate Logistic regression analysis showed that both UCH-L1 and netrin-1 were independent risk factors for poor neurological prognosis in basal ganglia hemorrhage patients(P<0.05).ROC curve analysis indicated that both markers had important predictive value for poor prognosis.The AUC for serum UCH-L1 level predicting poor prognosis was 0.77[95%confidence interval(CI):0.69～0.85,P<0.01],with a sensitivity of 84.9%and a specificity of 50.6%.The AUC for serum Netrin-1 level predicting poor prognosis was 0.89(95%CI:0.85～0.94,P<0.01),with a sensitivity of 82.1%and a specificity of 68.7%.Conclusions Serum UCH-L1 and Netrin-1 are differentially expressed in patients with spontaneous basal ganglia hemorrhage complicated with different volumes of cerebral edema.They are independent risk factors for poor prog-nosis and are important predictors of neurological function prognosis in these patients.

Objective:To report the 5-year survival outcomes and recurrence patterns of robotic total gastrectomy (RTG) for locally advanced proximal gastric cancer in order to provide more valuable long-term follow-up results for clinical practice.Methods:This was a prospective, single-arm, open-label clinical trial (FUGES-014; Clinical-Trials.gov, NCT03524287). Patients with locally advanced proximal gastric cancer who underwent RTG at Fujian Medical University Union Hospital from March 5, 2018, to February 10, 2020, were included in the analysis. To evaluate the long-term efficacy of RTG in the most objective manner possible, we performed a propensity score-matched (1∶2) comparative analysis with historical control patients who had undergone laparoscopic total gastrectomy (LTG) from the FUGES-002 study (ClinicalTrials.gov, NCT02333721) in which the 5-year disease-free survival (DFS), 5-year overall survival (OS), and recurrence patterns were compared between the two groups.Results:Prior to matching, there were 48 cases in the RTG group and 263 cases in the LTG group; patients in the LTG group had more advanced cT and pT stages ( P=0.044 and 0.006, respectively) compared to the RTG group. After matching, there were 48 cases in the RTG group and 96 cases in the LTG group; however, no statistically significant differences were observed in the baseline clinical characteristics between the two groups (all P>0.05). Both groups had a median follow-up of 72 months. The 5-year DFS rates were 75.0% (95%CI: 63.7%- 88.3%) in the RTG group and 61.4% (95%CI: 52.5%-72.0%) in the LTG group ( P=0.116). Similarly, the 5-year OS rates were 79.2% (95%CI: 68.5%-91.5%) and 64.6% (95%CI: 55.7%-74.9%) in the RTG and LTG groups, respectively ( P=0.100). Within 5 years after surgery, tumor recurrence occurred in 10 patients (20.8%) in the RTG group and 33 patients (34.4%) in the LTG group ( P=0.124), and peritoneal recurrence was the predominant pattern in both groups (8.3%[4/48] vs. 10.4%[10/96]; risk difference: -0.02, P=0.554). Gastric cancer-related death was the predominant cause of death in both groups (16.7% [8/48] vs. 31.2% [30/96]; risk difference: -0.15, P=0.064). Among patients stratified by different pathological stages, no statistically significant differences were found in DFS, OS, or recurrence rates between the RTG and LTG groups (all P>0.05). Conclusions:We find the long-term oncological outcomes of RTG for locally advanced proximal gastric cancer to be noninferior to those of LTG. RTG should therefore be considered as a valid option for standardized minimally invasive surgery for locally advanced proximal gastric cancer.

BACKGROUND: To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study. METHODS: This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well. RESULTS: The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P  <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n  = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β  <0, P  <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed. CONCLUSIONS: The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required. REGISTRATION Chinese Clinical Trial Registry (No. ChiCTR2200055247).

Objective To explore the association between the relative expression level of SNORD55 in peripheral blood and the outcomes of all-cause mortality and stroke in patients with atrial fibrillation(AF),and to evaluate the predictive value of SNORD55 for prognosis.Methods A total of 133 patients with non-valvular AF admitted in Department of Cardiology of the First Affiliated Hospital of Army Medical University from January 2014 to December 2017 were enrolled in this study.Their baseline information was collected,and the relative expression level of plasma SNORD55 was detected.Cox proportional hazards model was used to explore the association between the relative expression level of SNORD55 in peripheral blood and all-cause mortality as well as stroke in the patients.The predictive performance of CHA2DS2-VASc score for all-cause mortality and stroke was compared with the score combined with the relative expression level of SNORD55 in the AF patients.The area under the receiver operating characteristic curve(AUC)was utilized to evaluate the discrimination,and the net reclassification index(NRI)and comprehensive discriminant improvement index(IDI)were calculated to evaluate the improvement of reclassification ability.Decision curve analysis(DCA)was applied to analyze the change in clinical net benefit.Results The results of multivariate Cox regression showed that high expression of SNORD55 in peripheral blood was an independent risk factor for all-cause mortality and stroke in the AF patients.In predicting the outcomes of all-cause mortality and stroke,the addition of relative expression SNORD55 level with the CHA2DS2-VASc score obtained higher AUC value[0.80(95％CI:0.67～0.93)vs 0.67(95％CI:0.53～0.81),P＜0.05].In predicting the outcome of all-cause death and stroke,combination of the relative expression level of SNORD55 with CHA2DS2-VASc score increased both NRI[54.3(95％CI:10.6～61.9)vs 31.9(95％CI:2.8～47.5),P＜0.05]and IDI[16.1(95％CI:2.4～27.0)vs 7.9(95％CI:0.5～14.8),P＜0.05].The results of DCA showed that our combination of CHA2DS2-VASc score relative expression level of SNORD55 had higher clinical net benefits than the foreign ABC score in the prediction of the outcomes.Conclusion Peripheral blood SNORD55 level is an independent risk factor for all-cause mortality and stroke in AF patients,and has good predictive performance for all-cause mortality and stroke in the patients.

Objectives To explore the association of peripheral blood PIWI-interacting RNA,piR-hsa-2700592,with all-cause mortality and stroke outcomes in patients with atrial fibrillation(AF),and to determine whether piR-hsa-2700592 has the potential to be an AF biomarker.Methods A total of 127 patients with non-valvular AF were enrolled,and the relative expression level of plasma piR-hsa-2700592 was detected.Cox proportional hazard regression was used to analyze the correlation between the expression of piR-hsa-2700592 and all-cause death as well as stroke outcome in the patients.Then the molecule expression level was combined with CHA2DS2-VASc score and ABC stroke(or death)score to establish 2 new prediction models,the improvement of the predictive performance was compared and analyzed.Receiver operating characteristic(ROC)curve analysis(area under the curve,AUC),net reclassification index(NRI),and comprehensive discriminant improvement index(IDI)were used to evaluate the predictive performance,and decision curve analysis(DCA)was employed to assess the clinical benefit.Results Multivariate Cox regression analysis showed that the patients with higher expression level of piR-hsa-2700592 in peripheral blood had a higher risk of stroke(HR:2.203,95%CI:1.120～4.332;P=0.022).In the stroke outcome,combination of plasma piR-hsa-2700592 expression level with CHA2DS2-VASc score and ABC stroke score obtained an AUC of 0.70(95%CI:0.55～0.85,P＜0.001)and 0.84(95%CI:0.73～0.96,P=0.02),respectively.But,no significant association was observed between high plasma piR-hsa-2700592 level and all-cause mortality in the AF patients(HR:1.997;95%CI:0.884～4.509;P=0.096).Combination of plasma piR-hsa-2700592 level improved the discriminative capability than the single CHA2DS2-VASc score and ABC stroke score models,with an NRI and IDI value of 44.20%(95%CI:3.40～59.90,P＜0.001)and 8.20%(95%CI:0.60～15.40,P＜0.001),respectively for the new CHA2DS2-VASc score model,and an NRI and IDI value of 44.20%(95%CI:9.80～58.90,P＜0.001)and 10.40%(95%CI:0.70～21.40,P＜0.001),respectively for the new ABC stroke score model.The DCA curve showed that both new prediction models obtained better net clinical benefits.Conclusion High peripheral blood expression of piR-hsa-2700592 is an independent risk factor for stroke in the AF patients,and the indicator has a good predictive value for prognosis of the patients.piR-hsa-2700592 might be used as a potential biomarker in the diagnosis and prevention of cardiovascular diseases.
