Objective:To investigate the intervention effect of exercise rehabilitation based on constructivism teaching mode on pelvic girdle pain (PGP) in pregnant women in late pregnancy, and to provide guidance for improving the pregnancy experience of PGP pregnant women.Methods:A quasi-experimental study was conduced, from November 2023 to February 2024, using convenience sampling method to select late pregnant women with PGP who had been filed and had regular obstetric checkups in the Second Hospital of Shandong University as the study subjects, they were randomly divided into intervention group (granted exercise rehabilitation based on the constructivism teaching model) and control group (granted exercise rehabilitation based on the traditional teaching model) according to the random number table method. Compare the pain scores and teaching effectiveness of pregnant women before and after the intervention in the two groups.Results:The final number of the two groups were 50 in each group, aged (32.38 ± 3.93) years in the intervention group; aged (31.34 ± 3.19) years in the control group. After the intervention, the pain scores of pregnant women in the intervention group (1.48 ± 1.26) scores were significantly lower than those in the control group (2.96 ± 1.42) scores, and the difference was statistically significant ( t = -5.45, P<0.05). The scores of the evaluation of the teaching effect memory problem scores, movement mastery scores, and classroom evaluations were (7.96 ± 1.30) scores, (13. 96 ± 0.88) scores, (27.54 ± 3.08) scores in the intervention group, which were significantly higher than those in the control group (5.80 ± 1.29) scores, (8.48 ± 1.82) scores, (16.24 ± 3.80) scores, the differences were statistically significant ( t = 8.30, 19.16, 16.31, all P<0.05). Conclusions:Based on the constructivism teaching model, exercise rehabilitation for pregnant women with PGP in late pregnancy can effectively alleviate their pelvic girdle pain, and the teaching effect is better than the traditional teaching model, which has the potential to be promoted and applied in the teaching of obstetric maternity schools.

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 conduct a scoping review of studies on nurses' self-efficacy in disaster contexts,and to provide references for enhancing nurses' self-efficacy in disaster response.Methods Guided by the methodology of scoping review,we systematically searched PubMed,Web of Science,Cochrane Library,CINAHL,China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP Database,and China Biology Medicine disc(CBM)from inception to July 3,2025.Totally 2 researchers independently screened the search results,summarized them,and extracted relevant data.Results A total of 21 studies were included.Nurses' self-efficacy in disaster contexts was generally at a moderate level,influenced by multiple factors including sociodemographic characteristics,occupational background,and physical and mental health status.The main assessment tools were the General Self-Efficacy Scale and the Disaster Response Self-Efficacy Scale.Interventions included psychological first aid training,scenario simulation training,and immersive movie escape room training.Conclusion Nurses' self-efficacy in disaster contexts is generally at a moderate level with multiple influencing factors.Relevant assessment tools need further optimization,and interventions require further refinement.

The incidence of leukemia,a malignant cancer originating from the hematopoietic system,is increasing annually.Although traditional treatment method such as chemotherapy and hematopoietic stem cell transplantation have improved patient survival rates to some extent,serious side effects,drug tolerance,and high recurrence rates remain.In recent years,studies have shown that the gut microbiota and its metabolites play an important role in the occurrence,development,and complications of leukemia.Imbalance of the gut microbiota can lead to decreased immune function and an intensified inflammatory response,which is a key factor driving disease progression.Some metabolites,such as short-chain fatty acids,enhance immune function and improve patient prognosis through intestinal barrier repair,while others,such as hydrogen sulfide and bile acids,show potential anti-tumor effects exerted through regulation of tumor cell apoptosis and immune balance.Traditional Chinese medicine aimed at regulating the structure of the gut microbiota and its metabolites has shown great potential in alleviating the side effects of chemotherapy for leukemia.This review covers the role of the gut microbiota and its metabolites in the occurrence,development,and complications of leukemia,and explores treatment strategies for regulating the microbiota,including fecal microbiota transplantation,probiotics,and traditional Chinese medicine intervention.We anticipate that this review will serve as a reference for improving the treatment and prognosis of leukemia.

Objective To investigate the status and influencing factors of psychological distress associated with weight loss among young and middle-aged adults with obesity,so as to provide a theoretical basis for developing personalized interventions and improving psychological well-being.Methods A convenience sampling method was used to select young and middle-aged obese patients who visited the weight management clinic of a Grade A tertiary hospital in Jiangxi Province from October 2024 to May 2025.Data were collected using a general information questionnaire,the distress thermometer,the perceived social support scale,the brief illness perception questionnaire,and the simplified coping style questionnaire.Binary logistic regression was applied to identify factors influencing psychological distress.Results A total of 204 valid questionnaires were collected.The detection rate of significant psychological distress was 58.82%(120 cases).Regarding weight loss methods,32.84%of participants opted for medication.The top five issues reported on the psychological distress problem list were:appearance/body image,work/studies,lack of time/energy to care for elderly parents or children,bathing/dressing,and relationship with a partner.Binary logistic regression indicated that age,body mass index,waist circumference,history of chronic disease,perceived social support,illness perception,and negative coping style were significant influencing factors of psychological distress(P﹤0.05).Conclusions The rate of significant psychological distress is relatively high among young and middle-aged obese patients and is influenced by multiple factors.Medical staff may develop personalized interventions based on these factors to reduce the incidence of psychological distress.
