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.

Objective To explore the protective effect of polydatin and its mechanism on secondary liver injury in silicosis rats based on network pharmacology and animal experiments. Methods i) Network pharmacology study. Based on multiple databases, the targets of polydatin effect related to silicosis and liver injury were collected, and the common targets of polydatin-silicosis-liver injury were screened to construct a protein-protein interaction network. Enrichment analyses were performed to identify core targets involved in the effects of polydatin on silicosis-associated secondary liver injury. The mechanism of action of polydatin in relieving silicosis and silicosis-associated secondary liver injury was investigated, in which polydatin served as molecular docking ligand. ii) Animal experimental validation. Specific pathogen free male SD rats were randomly divided into three groups, with 10 rats per group. Rats in the model and intervention groups received 1 mL of a silica suspension at a mass concentration of 50 g/L for modeling using a one-time non-tracheal exposure method. Then rats in the intervention group were injected intraperitoneally with polydatin solution at 30 mg/kg body weight, once daily starting from the first day after silica exposure, whereas rats in the control group received no treatment. Lung and liver histopathology of rats, which were randomly sacrificed on days 28 and 56 post-exposure in both groups, were examined. Biomarkers of liver injury and hepatic oxidative stress were measured, and hepatic expression of nuclear factor erythroid 2-related factor 2 (NRF2) related proteins was detected by Western blotting. Results i) Network pharmacology study results. A total of 137 polydatin-related targets, 14 812 silicosis-related targets, and 3 038 liver injury-related targets were identified, among which 69 were common targets and 28 were key targets. Gene Ontology analysis indicated that the key targets were involved in 1 883 pathways. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis identified 137 pathways related to the targets. Molecular docking showed good binding affinities between polydatin and B-cell lymphoma 2 (BCL2), interleukin 6 (IL-6), tumor necrosis factor (TNF), and NRF2. ii) Animal experimental validation results. Compared with the control group, rats in the model group showed increased collagen deposition in both lung and liver tissues, with hepatic degeneration, necrosis, and inflammatory cell infiltration on days 28 and 56 after silica exposure. The collagen in lung and liver tissues of rats on days 28 and 56 after silica exposure increased in the model group compared with the control group (all P<0.05). Meanwhile, serum alanine aminotransferase and aspartate aminotransferase activities, hepatic lactate dehydrogenase 5 activities and NADPH: quinone oxidoreductase 1 (NQO1) expression in liver tissue increased (all P<0.05), whereas hepatic superoxide dismutase activity and NRF2 expression were decreased (all P<0.05). The level of malondialdehyde and the relative expression of heme oxygenase-1 (HO-1) protein in liver tissue in rat of model group were higher than those in the control group (all P<0.05). These alterations were ameliorated in rats of the intervention group compared with the model group (all P<0.05). Conclusion Polydatin exerts protective effects against secondary liver injury in rats with silicosis. These effects may be mediated by regulation of core targets such as BCL2, IL6, TNF, and NRF2, modulation of inflammatory pathways including TNF and IL17 signaling, and activation of the NRF2/HO-1 pathway, thereby exerting synergistic anti-inflammatory, antioxidant, and antifibrotic effects via the "lung-liver axis".

SPSS 24.0 was used for statistical analysis; the t-test was used for continuous data, and the chi-square test was used for categorical data. Results:There were no significant differences between the two groups in terms of age, sex, educational level, residency grade, and comprehensive ability assessment before the study. After the first stage of training, compared with the control group, the research group had significantly better theoretical assessment score [(85.30±3.39) vs. (81.15±4.66), P=0.003], skill assessment score [(83.95±4.37) vs. (79.70±6.20), P=0.017], and effective communication ability (95.00% vs. 65.00%, P=0.048) and team collaboration ability (100.00% vs. 65.00%, P=0.013) in questionnaire survey of the degree of satisfaction with teaching. After the second stage of training, both groups had significant increases in theoretical assessment score [the research group: (89.30±4.12) vs. (85.30±3.39), P=0.002; the control group: (88.90±3.49) vs. (81.15±4.66), P<0.001] and skill assessment score [the research group: (88.40±4.84) vs. (83.95±4.37), P=0.004; the control group: (86.20±4.98) vs. (79.70±6.20), P=0.001], and the questionnaire survey showed that a relatively high degree of satisfaction (95.00%-100.00%) was achieved for teaching effect, while there were no significant differences in each indicator between the two groups. Conclusions:Compared with conventional teaching rounds, PBL-CTU teaching rounds significantly improve the levels of theoretical knowledge and clinical operation ability and enhance the quality of teaching rounds. All residents have achieved satisfactory learning outcomes and progress after the two stages of teaching activities.

Objective To analyze the modeling and evaluation method for vascular restenosis animal models in the last 10 years,to provide a reference for improving animal models of vascular restenosis.Methods Literature related to vascular restenosis was retrieved from mainstream Chinese and English databases from 2013 to 2023.Data on experimental animal strains,modeling method,modeling cycles,and detection method were extracted from the included literature,and a database was established using Excel for summary analysis.Results Among the 122 identified articles,the main experimental animals were rats,rabbits,and pigs,and most animals were male.The most common modeling method was balloon injury,and the modeling cycle was mainly within 4～8 weeks.The main detection indexes were histopathology,accounting for 37.18％,including routine hematoxylin-eosin,Masson,and Elastica van Gieson(EVG)staining.Conclusions The translatability of porcine vascular restenosis models is currently more in line with expectations,but their cost is high and they are unpopular,and rats and rabbits thus remain the main animal models.Balloon injury is the main mode of modeling.Different animal models and modeling method for vascular restenosis have advantages and disadvantages,and the model should be selected according to the experimental purpose.Animal models of vascular restenosis still have some limitations,however,and better animal models are required in the future.

Objective:To evalaute the role of hippocampal ubiquinol cytochrome C reductase core protein 1 (UQCRC1) in cognitive dysfunction after global cerebral ischemia (GCI) in mice.Methods:Forty SPF healthy male C57BL/6J mice, aged 12 weeks, weighing 22-26 g, were selected, and 20 of them were divided into 2 groups ( n=10 each) using a random number table method: sham operation group and GCI1 group. The other 20 mice were divided into 2 groups ( n=10 each) by the random number table method: GCI2 group and GCI+ UQCRC1 overexpression group (GCI+ UQCRC1 group). In Sham group, the skin was directly sutured after exposing both common carotid arteries. Global cerebral ischemia was induced by occlusion of bilateral common carotid arteries for 20 min in GCI1, GCI2 and GCI+ UQCRC1 group, and lentivirus VSVG-Lentivirus-hSyn-EGFP-P2A-UQCRC1-WPRE-pA 500 nl was injected into the bilateral hippocampus at 2 weeks before developing the model in GCI+ UQCRC1 group. The novel object recognition task was carried out on the 2nd day following completion of model development, and the percentage of time spent exploring the novel object was calculated. The fear conditioning test was carried out on days 3-4 after completion of model development, and the freezing time was recorded. Morris water maze test was performed on days 5-10 after completion of model development, and the escape latency and time spent in the target quadrant were recorded. After the Morris water maze test, the expression of UQCRC1 in the hippocampal CA1 region was detected by immunofluorescence and Western blot. Results:Compared with Sham group, the percentage of time spent exploring the novel object was significantly decreased, the percentage of freezing time in training and test stages was decreased, the escape latency on days 6-9 was prolonged, the percentage of time spent in the target quadrant was decreased, and the expression of UQCRC1 in the hippocampal CA1 was down-regulated in GCI1 group ( P<0.05). Compared with GCI2 group, the percentage of time spent exploring the novel object was significantly increased, the percentage of freezing time in training and test stages was increased, the escape latency on days 6-9 was shortened, the percentage of time spent in the target quadrant was increased, and the expression of UQCRC1 in the hippocampal CA1 region was up-regulated in GCI+ UQCRC1 group ( P<0.05). Conclusions:Hippocampal UQCRC1 is involved in the process of cognitive dysfunction following GCI in mice.

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.
