Background Patients with pneumoconiosis often have limited disease-related knowledge, insufficient access to health education, and substantial health management needs. Health education may help improve rehabilitation outcomes and quality of life in this population. Objective To evaluate the effects of health education based on the Listen-Establish-Adopt-Reinforce-Name-Strength (LEARNS) model on rehabilitation outcomes, health-related behaviors, and quality of life among pneumoconiosis patients, and provide effective intervention strategies for the rehabilitation management of patients with pneumoconiosis. Methods A randomized controlled trial was conducted. A total of 120 pneumoconiosis patients treated in the Department of Occupational Diseases, Beijing Emergency General Hospital, from November 2024 to February 2025 were enrolled. Participants were randomly assigned to a control group or an intervention group using a random number table method, with 60 patients in each group. The control group received routine pharmacotherapy, whereas the intervention group received a 12-week LEARNS model-based health-education intervention in addition to routine treatment. The 6-Minute Walk Test (6MWT) was used to assess exercise tolerance, and the modified Medical Research Council dyspnoea scale (mMRC) was used to evaluate dyspnoea. The Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were applied for psychological status assessment. Pulmonary function, including forced expiratory volume in one second (FEV₁) and forced vital capacity (FVC), was measured using spirometry. A self-designed scale was used to evaluate eight health-related behaviors targeted by the health education program. The 36-Item Short-Form Health Survey (SF-36) and Chronic Obstructive Pulmonary Disease (COPD) Assessment Test (CAT) were used to assess quality of life, and the Pittsburgh Sleep Quality Index (PSQI) was adopted to evaluate sleep quality. Results After the 12-week intervention, the control group showed no statistically significant changes from baseline in the measured outcomes(P＞0.05). In the intervention group, exercise tolerance improved significantly, with the 6-minute walking distance increasing from (382.55±19.52) m to (426.84±33.59) m (P＜0.001). Dyspnoea was also alleviated, with the mMRC score decreasing from 1.37±0.66 to 0.96±0.54 (P＜0.001). The CAT score decreased from 18.95±7.03 to 10.67±3.64 (P＜0.001). Significant improvements were observed in anxiety and depression symptoms (P＜0.001), with the SAS score decreasing from 38.85±6.24 to 34.27±2.27, and the SDS score decreasing from 49.01±3.25 to 45.49±3.44. Sleep quality improved significantly, with the PSQI score dropping from 7.89±4.35 to 4.05±2.31 (P＜0.001). All eight health-related behaviors in the intervention group improved significantly after the intervention (P＜0.001), including acquisition of disease-related knowledge (1.87±0.34 vs. 3.13±0.45), participation in health education activities (1.89±0.52 vs. 3.61±0.38), and regular physical exercise (2.37±0.41 vs. 4.17±0.33). All SF-36 domain scores increased significantly (P＜0.05), with the most prominent improvements observed in physical functioning, general health, and vitality. At week 12, all SF-36 domain scores were significantly higher in the intervention group than in the control group (P＜0.05). No statistically significant between-group differences were detected in pulmonary function parameters (P＞0.05). Conclusion LEARNS model-based health education could improve exercise tolerance, dyspnea, psychological status, sleep quality, health-related behaviors, and quality of life among patients with pneumoconiosis, and therefore may be a useful adjunctive strategy for rehabilitation management in patients with pneumoconiosis.

Metabolic dysfunction-associated fatty liver disease （MAFLD） is the chronic liver disease with the highest prevalence rate globally， and its disease spectrum encompasses a progressive continuum from hepatic steatosis to metabolic dysfunction-associated steatohepatitis， liver fibrosis， liver cirrhosis， and eventually hepatocellular carcinoma. In recent years， the research paradigm of MAFLD has shifted from “lipid accumulation” to “lipid metabolic reprogramming”， which， as a critical link in disease development and progression， is regulated by multidimensional molecular networks. This article systematically reviews the molecular mechanisms of lipid metabolic reprogramming in MAFLD from the following aspects： it analyzes the core role of lipid metabolism disorders， with a focus on how dysregulation of membranous organelle interactions， such as endoplasmic reticulum-mitochondria contacts， mediates metabolic imbalance； it concentrates on novel programmed cell death pathways induced by lipotoxicity， especially ferroptosis， and reveals the pathways through which they exacerbate liver injury； furthermore， it comprehensively analyzes the multi-layered regulatory network of the key signaling pathways such as adenosine monophosphate-activated protein kinase and nuclear factor-erythroid 2-related factor 2 and explores the emerging mechanisms such as liquid-liquid phase separation and microprotein regulation； finally， it provides an outlook on the potential therapeutic strategies targeting critical nodes of lipid metabolic reprogramming， so as to provide a theoretical basis for investigating the pathological mechanisms of MAFLD and developing precise interventions.

ObjectiveTo systematically review the association between non-alcoholic fatty liver disease （NAFLD） and depression， and to provide a basis for synergistic management in clinical practice. MethodsThis study was conducted according to the PRISMA guidelines， with the PROSPERO registration number of CRD42023482013. PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang Data， VIP， and CBM were searched for articles on the association between NAFLD and depression published up to November 1， 2024. The articles were screened according to the inclusion and exclusion criteria， and related data were extracted. RevMan 5.3 was used to perform the Meta-analysis. ResultsA total of 18 studies were included， involving 396 793 participants. Among these studies， 12 discussed the influence of NAFLD on depression， involving 224 269 participants， among whom there were 75 574 patients with NAFLD. The Meta-analysis showed that NAFLD was significantly associated with the risk of depression （odds ratio ［OR］=1.21， 95% confidence interval ［CI］： 1.12 — 1.30， P0.001）. Six studies examined the influence of depression on NAFLD， involving 172 524 participants， among whom there were 29 368 patients with depression. The meta-analysis showed that depression caused a significant increase in the risk of NAFLD （OR=1.13， 95%CI： 1.05 — 1.22， P=0.001）. ConclusionThere is a significant bidirectional association between NAFLD and depression. It is recommended to perform the screening for depression and enhance mental health monitoring in patients with NAFLD， and metabolic function assessment and exercise intervention should be performed for patients with depression.

Objective:To evaluate the efficacy and safety of nebulized inhalation of recombinant human interferon (IFN) α1b injection in the treatment of respiratory syncytial virus (RSV) associated lower respiratory tract infections (pneumonia and bronchiolitis) in children.Methods:A randomized, double-blind, parallel, placebo-controlled add-on design was used.Children with pneumonia or bronchiolitis aged 2 months to 5 years who tested positive for RSV antigen within 72 hours of onset from 30 clinical trial sites including Beijing Children′s Hospital, Capital Medical University between February 2021 and December 2022 were included in this study and randomly divided into 2 groups at a ratio of 1∶1 based on a stratified-block method.Both groups received basic treatments such as cough control, asthma relieving, expectorant treatment, fever reduction, oxygen therapy, etc.The experimental group received additional nebulized inhalation of IFN α1b injection at a dose of 2.0 μg/(kg·time), twice a day.The control group received nebulized inhalation of placebo twice a day.Clinical efficacy was evaluated based on indicators such as the duration of clinical symptoms and signs, and the Kaplan-Meier method was used to calculate the median and 95% CI of the duration of clinical symptoms and signs.The Log-rank test was used to compared data between groups.Safety was assessed through the incidence of adverse reactions and laboratory tests, and the Chi-square test was used to analyze the difference between groups. Results:There were 123 children in the experimental group and 122 children in the control group.The median durations of all the 5 clinical symptoms and signs [including shortness of breath, wheezing, dyspnea (visible retractions), decreased transcutaneous oxygen saturation, and abnormal mental state] in the experimental group after treatment were slightly shortened than those in the control group [2.7 d(95% CI: 1.9-3.0 d)] vs.[2.9 d(95% CI: 2.6-3.6 d), P=0.027].The improvement in dyspnea (retractions) was especially pronounced in the experimental group, with a relief rate of 50.0% (0, 100%) on the first day of administration[compared with 0 (0, 50.0%) in the control group ( Z=2.002, P=0.025)].The median duration of dyspnea in the experimental group was nearly 1 day shorter than that in the control group [1.0 d(95% CI: 0.7-1.7 d) vs.1.8 d(95% CI: 1.0-2.5 d), P=0.046].There were no significant difference in hospital stay [6.0(5.0, 8.0) d vs.6.5(5.0, 8.0) d, Z=0.675, P=0.500], oxygen therapy duration [32.0(14.0, 96.3) h vs.39.0 (24.0, 83.2) h, Z=0.094, P=0.925], the recovery rate from clinical symptoms during treatment [(105/106, 99.1%) vs.(96/101, 95.0%)], and recurrence rate [(0/106, 0) vs.(2/101, 2.0%)] between the 2 groups (all P>0.05).However, the above-mentioned four indicators in the experimental group showed a trend of clinical benefits.The quantitative virus detection results showed that the RSV viral load in both groups decreased after treatment compared to before treatment.After 2 days of treatment, the decline rate of RSV viral load from the baseline was 0.90 lg copies/(mL·d) in the experimental group and 0.25 lg copies/(mL·d)in the control group, with a statistically significant difference ( P<0.05).Furthermore, there was no statistically significant difference in the incidence of adverse reactions between the 2 groups ( P>0.05).Importantly, no drug-related serious adverse reactions occurred in both groups. Conclusions:The nebulized inhalation therapy of IFN α1b demonstrates efficacy and safety in treating pediatric RSV associated lower respiratory tract infections.It particularly offers outstanding clinical therapeutic value for severe children.

Background At present, the practice of pulmonary rehabilitation for pneumoconiosis in China is in a primary stage. The basis for formulating an individualized comprehensive pulmonary rehabilitation plan is still insufficient, which is one of the factors limiting the development of community-level rehabilitation work. Objective To formulate an exercise prescription based on maximum heart rate measured by cardiopulmonary exercise test (CPET), conduct an individualized comprehensive pulmonary rehabilitation program with the exercise prescription for patients with stable pneumoconiosis, and evaluate its role in improving exercise endurance and quality of life, thus provide a basis for the application and promotion of pulmonary rehabilitation. Methods A total of 68 patients were recruited from the Occupational Disease Prevention Hospital of Jinneng Holding Coal Industry Group Co., Ltd. from April to August 2022 , and were divided into an intervention group and a control group by random number table method, with 34 cases in each group. All the pneumoconiosis patients participated in a baseline test. The control group was given routine drug treatment, while the intervention group received multidisciplinary comprehensive pulmonary rehabilitation treatment on the basis of routine drug treatment, including health education, breathing training, exercise training, nutrition guidance, psychological intervention, and sleep management, whose exercise intensity was determined according to the maximum heart rate provided by CPET. The rehabilitation training lasted for 24 weeks. Patients were evaluated at registration and the end of study respectively. CPET was used to measure peak oxygen uptake per kilogram (pVO₂/kg), anaerobic threshold (AT), carbon dioxide equivalent of ventilation (EqCO₂), maximum metabolic equivalent (METs), and maximum work (W_max). The modified British Medical Research Council Dyspnea Questionnaire (mMRC), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Pittsburgh Sleep Quality Index (PSQI), Chronic Obstructive Pulmonary Disease Assessment Test (CAT), and Short Form of Health Survey (SF-36) were used to evaluate the potential effect of the comprehensive pulmonary rehabilitation program. Results Among the included 68 patients, 63 patients were having complete data, then 31 cases were assigned in the control group and 32 cases in the interventional group. Before the intervention, there was no significant difference in pVO₂/kg, AT, EqCO₂, METs, or W_max between the two groups (P>0.05). At the end of the trail, the indicators like pVO₂/kg [(19.81±2.38) mL·(min·kg)⁻¹], AT [(14.48±2.33) mL·(min·kg)⁻¹], METs (5.64±0.69), and W_max [(85.25±14) W] of patients in the intervention group were all higher than those [(13.90±2.37) mL·(min·kg)⁻¹, (11.70±1.94) mL·(min kg)⁻¹, (3.97±0.70), and (61.77±14.72) W, respectively] in the control group (P<0.001); there was no significant difference in EqCO₂ between the two groups (P=0.083). Before the trial, there was no significant difference in mMRC, SAS, SDS, PSQI, or CAT scores between the two groups (P>0.05). At the end of the trail, the mMRC score (1.16±0.57), SAS score (27.93±2.12), SDS score (26.48±1.44), PSQI score (1.08±0.88), and CAT score (4.34±3.28) of patients in the intervention group were lower than those [(2.03±0.83), (35.87±6.91), (34.23±6.65), (5.37±3.03), and (13.87±7.53), respectively] in the control group (P<0.001). The SF-36 scores of bodily pain (94.13±10.72), general health (87.50±5.68), vitality (95.31±5.53), mental health (99.88±0.71), and health changes (74.22±4.42) in the intervention group were higher than those [(71.87±32.72), (65.81±15.55), (74.52±16.45), (86.97±16.56), and (29.84±13.50), respectively] in the control group (P<0.001), and no significant difference was found in social functioning and role emotional scores (P>0.05). Conclusion Comprehensive pulmonary rehabilitation can increase the oxygen intake and exercise endurance of pneumoconiosis patients, ameliorate dyspnea symptoms, elevate psychological state and sleep quality, and improve the quality of life.

Objective:To explore the effect of multidisciplinary management combined with 60-second high-risk diabetic foot screening in diabetic foot.Methods:From January to December 2022, 138 patients with diabetic foot were selected from Xinxiang Central Hospital by convenience sampling. The patients were randomly divided into a control group and an observation group, with 69 cases in each group. Control group implemented routine follow-up management of diabetic foot, and observation group carried out multidisciplinary management combined with 60-second high-risk diabetic foot screening on the basis of control group, and the intervention lasted for six months. The progress of Wagner grading of diabetic foot and foot self-care were compared between the two groups.Results:After intervention, the number of Wagner grading progression patients in observation group and control group was four cases (5.80%) and 10 cases (14.49%), respectively. The number of progression patients in observation group was less than that in control group, and the difference was statistically significant (χ 2=4.161, P=0.041). The total score and dimension scores of diabetic foot self-management in the two groups after the intervention were higher than those before the intervention, but only the scores of observation group before and after the intervention were statistically significant ( P<0.05). After intervention, the total score and dimension scores of diabetic foot self-management in observation group were higher than those in control group, with a statistically significant difference ( P<0.05) . Conclusions:Multidisciplinary management combined with 60-second high-risk diabetic foot screening can effectively delay the progress of diabetic foot and improve patients' foot self-care.

Objective:To investigate the epidemiological and clinical characteristics of human parainfluenza viruses (HPIVs) infection among hospitalized children with community-acquired pneumonia (CAP) in China, and provide basic data for diagnosis, treatment and prevention of HPIVs infection.Methods:From November 2014 to February 2020, 5 448 hospitalized children with CAP were enrolled in 14 hospitals in 11 provinces and municipalities directly under the Central Government in southern China and northern China. Nasopharyngeal aspirates or throat swabs were collected, and the nucleic acids of 18 types respiratory viruses including HPIV1-4 were screened by suspension array technology. Demographic data and clinical information were collected for statistical analysis.Results:The total detection rate of HPIVs in 5 448 children with CAP was 8.83% (481/5 448), and the detection rate in males was higher than that in females (62.79% vs. 37.21%; χ2=0.000, P=0.992). The detection rate of HPIVs in 1~< 3 years age group was higher than that in other age groups, and the difference was statistically significant ( χ2=61.893, P<0.001). The detection rate of HPIVs in the northern region was higher than that in the southern region (9.02% vs 8.65%), but the difference was not statistically significant ( χ2=0.239, P=0.625). The prevalence of HPIV1-4 in northern and southern China was not completely same. HPIV1 was mainly prevalent in autumn in both northern and southern regions. HPIV2 was prevalent in summer in northern China, and the detection rate was low in southern China. HPIV3 reached its peak in both spring and summer in both northern and southern China, but its duration was longer in southern China than in northern China. HPIV4 is mainly popular in autumn in both southern China and northern China. Among 481 children infected with HPIVs, 58.42% (281/481) were infected with HPIV alone, and the main clinical manifestations were cough (90.75%) and fever (68.68%). Out of the HPIV-positive cases, 42.62% (205/481) were co-infected with another type of HPIV or a different virus, while 11.43% (55/481) had co-infections with two or more different viruses. HPIV3 was the most common type of co-infection with other viruses. HPIV3 infection accounted for the largest proportion (76.80%) in 47 HPIVs-positive children with severe pneumonia. Conclusions:HPIVs is one of the most important pathogens causing CAP in children in China, and children under 3 years of age are the main populations of HPIVs infection. The prevalence characteristics of all types of HPIVs in children in the north and south are not completely same. HPIV3 is the dominant type of HPIV infections and causes more severe diseases.

Objective:To explore the effects of WeChat-based CT enhanced examination process on the examination efficiency of patients undergoing CT enhanced examination.Methods:Totally 178 patients who received CT enhanced examination in the Department of Radiology (Intervention) , China-Japan Union Hospital of Jilin University from January 2019 to December 2020 were selected by random sampling, of which 87 patients from January to December 2019 were included in the control group, while 91 patients from January to December 2020 were included in the observation group. Patients in the control group were subjected to routine procedures, while patients in the observation group were subjected to WeChat-based enhanced CT examination procedures. The Patient Satisfaction Questionnaire Short Form (PSQ-18) and China Occupational Strain Scale (COSS) were used to investigate the patients and compare the CT-enhanced examination efficiency, patient satisfaction and occupational tension of medical staff between the two groups. Totally 12 medical staff who worked in the Department of Radiation (Intervention) of China-Japan Union Hospital of Jilin University from January 2019 to December 2020 were selected by random sampling to investigate the impact of process optimization on the working conditions of medical staff. A total of 12 questionnaires were distributed to medical staff in this study, and 12 valid questionnaires were recovered, with an effective recovery rate of 100.00%.Results:The appointment time, waiting time, preparation time before examination and total examination time of the observation group were all shorter than those of the control group, and the difference was statistically significant ( P<0.01) . In addition, the PSQ-18 scores and total scores of patients in the observation group were higher than those in the control group, except for interpersonal communication skills of the follow-up personnel and the communication level of the follow-up personnel, and the difference was statistically significant ( P<0.05) . The COSS scores and total scores of medical staff in the observation group were lower than those in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The WeChat-based CT enhanced examination process can help improve the inspection efficiency among patients undergoing CT enhanced examination, improve patient satisfaction, and reduce the occupational tension of medical staff.

Objective:To explore the effect of health education based on action research theory and swallowing rehabilitation nursing for stroke patients with dysphagia.Methods:The random sampling method was used to select 128 stroke patients with dysphagia who were admitted to China-Japan Union Hospital of Jilin University from November 2020 to November 2021. According to the random number table method, they were divided into the control group and the experimental group. The control group received swallowing rehabilitation nursing, while the experimental group received action research theory health education on the basis of the control group. The swallowing function, self-care ability and quality of life were compared between the two groups.Results:Before nursing, there was no statistically significant difference in scores of Standardized Swallowing Assessment (SSA) , Exercise of Self-Care Agency (ESCA) and Swallowing-Quality of Life (SWAL-QOL) between the two groups ( P>0.05) . After 3 months of nursing, the SSA score of the two groups was lower than that before nursing, and the experimental group was lower than that of the control group, and the differences were statistically significant ( P<0.05) . The scores of each dimension of ESCA scale in the two groups were higher than those before nursing and the experimental group were higher than the control group, and the differences were statistically significant ( P<0.05) . The scores of each dimension of SWAL-QOL scale in the two groups were higher than those before nursing, and the experimental group were higher than the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The application of action research theory health education combined with swallowing rehabilitation nursing in stroke patients with dysphagia can improve the swallowing function of patients, self-care ability and quality of life.
