Objective To investigate the impact of various health education intervention strategies on the proper use of personal respiratory protective equipment (RPE) among workers exposed to dust. Methods Dust-exposed workers were recruited from 60 selected enterprises in Guangdong Province using cluster random sampling method. They were randomly allocated to the control, low-intensity intervention, and high-intensity intervention groups, with 358, 346, and 371 workers in each group, respectively. Workers in the control group received no designed intervention. Workers in the low-intensity intervention group received traditional plus mobile health education on the proper use of RPE. Workers in the high-intensity intervention group received all components of the low-intensity intervention, supplemented with peer education. The intervention lasted for six months. RPE usage was compared among the three groups of workers before and after the intervention. Results Workers in the control, low-intensity intervention, and high-intensity intervention groups showed higher rates of both RPE wearing and correct RPE wearing after the intervention than before it within their respective groups (RPE wearing rate: 94.1% vs 99.2%, 95.7% vs 100.0%, 94.6% vs 100.0%, all P<0.01; correct RPE wearing rate: 66.8% vs 91.1%, 67.3% vs 95.7%, 66.6% vs 96.5%, all P<0.01). Post-intervention correct RPE wearing rates were highest in the high-intensity intervention group, followed by the low-intensity intervention group, and the control group, with the percentage of 96.50%, 95.66% and 91.06%, respectively (P<0.01). Binary logistic regression analysis result showed that different intervention strategies affected the correct use of personal RPE among dust-exposed workers after adjusting for gender, age, and other confounding factors (P<0.05). Compared with the control group, the rates of correct RPE use increased in the low-intensity intervention group and the high-intensity intervention group (odd ratio was 2.14 and 3.01; 95% confidence interval was 1.12 - 4.10 and 1.53 - 5.91, respectively). Conclusion The implementation of traditional plus mobile health education interventions on the proper use of RPE can promote correct RPE utilization among dust-exposed workers, and integrating peer education further enhances the intervention effectiveness.

Objective:To explore the diagnostic value of blood flow parameters of carotid ultrasound combined with serum Sortilin and paraoxonase-1 (PON-1) for stability of carotid atherosclerotic plaque (CAP). Methods:A total of 100 CAP patients who admitted to Rugao Hospital of Traditional Chinese Medicine from January 2021 to December 2023 were selected,and they were divided into a stable plaque group (n=54) and a unstable plaque group (n=46). Enzyme linked immunosorbent assay (ELISA) was adopted to determine the expression levels of serum Sortilin and PON-1 of patients in two groups. Multi factor logistic regression was implemented to analyze the influencing factors on CAP stability. The receiver operating characteristic (ROC) curves were drawn to analyze the diagnostic efficiency of blood flow parameters of carotid ultrasound combined with Sortilin and PON-1 on CAP stability. Results:Compared with the end diastolic blood flow velocity (EDV) and intima-media thickness (IMT) of stable plaque group,unstable plaque group showed increased EDV and IMT,and decreased PSV,and the differences were significant (t=7.536,4.680,5.487,P<0.05),respectively. Compared with stable plaque group,the serum Sortilin level in unstable plaque group significantly increased,while the PON-1 level significantly decreased,and the differences of them were significant (t=8.362,5.581,P<0.05),respectively. Multivariate logistic analysis found that Sortilin was a risk factor that affected CAP stability (OR=3.165,P<0.05),while PON-1 was a protective factor that affected CAP stability (OR=0.765,P<0.05). ROC curve analysis indicated that the area under curve (AUC) values of single Sortilin,PON-1,EDV,IMT,PSV,and the combination of them were respectively 0.788 (95％CI:0.695-0.864),0.814 (95％CI:0.724-0.885),0.847 (95％ CI:0.761-0.911),0.767 (95％ CI:0.672-0.846),0.707 (95％ CI:0.607-0.793) and 0.963 (95％ CI:0.839-0.907). The AUC value of the combination of above 5 indicators was highest,which was better than that of each single indicator,and its sensitivity and specificity were respectively 95.65％ and 83.33％. Conclusion:The EDV,IMT and PSV of blood flow parameters of ultrasound can provide CAP information of morphology and hemodynamics,and serum Sortilin level and PON-1 level can reflect the biological processes of formation and development of CAP. The combined detection of the five indicators can better diagnose CAP stability.

Objective We aimed to investigate the effects of different non-surgical embryo transfer devices,number of transferred embryos,embryo stage,and embryos obtained from different mouse strains on the efficiency of non-surgical embryo transfer in mice,and to compare the efficiencies of surgical and non-surgical embryo transfer,in order to establish a stable non-surgical embryo transfer technology system.Methods Mouse embryo transfer was carried out using non-surgical method.Results The pregnancy rates using two different non-surgical transfer devices were(75.00±0.00)％and(66.67±14.43)％,and the birth rates were(46.11±6.31)％and(18.89±0.96)％,respectively.Transfer of 10,15,and 20 embryos resulted in pregnancy rates of(66.67±11.55)％,(80.00±0.00)％,and(66.67±23.09)％,and birth rates of(29.33±4.16)％,(38.67±4.81)％,and(17.00±3.46)％,respectively.When blastocysts and morulae were transferred non-surgically,the resulting pregnancy rates were(80.00±0.00)％and(46.67±11.55)％and the birth rates were(38.67±4.81)％and(10.22±2.77)％,respectively.Four strains(C57BL/6J,ICR,genetically modified mice A,genetically modified mice B)were used as donors for non-surgical embryo transfer,with resulting pregnancy rates of(66.67±11.55)％,(80.00±0.00)％,(73.33±11.55)％,and(80.00±0.00)％,and birthrates of(26.67±2.67)％,(38.67±4.81)％,(32.00±3.53)％,and(29.34±2.31)％,respectively.Fifteen pseudo-pregnant mice were transplanted surgically and 15 were transplanted non-surgically,with pregnancy rates of(80.00±0.00)％and(86.67±11.55)％,and birth rates of(38.67±4.81)％and(36.00±5.82)％,respectively.Conclusions Transfer device A resulted in a higher birth rate in this study.The embryo transfer efficiency was higher when 15 embryos were transferred into unilateral uterine horns of pseudo-pregnant 2.5-day recipients.Blastocyst-stage embryo transfer was more efficient than morula-stage transfer.There was no significant difference in efficiency between surgical and non-surgical embryo transfer procedures.

Objective To develop and validate risk prediction models utilizing five machine learning algorithms for assessing postoperative pulmonary infection(PPI)risk in lung cancer patients undergoing grade Ⅳ thoracoscopic surgery.Methods A retrospective cohort study included 2,380 lung cancer patients who underwent grade Ⅳ thoracoscopic surgery at a tertiary hospital in Shanghai(January 2022 to June 2024).Patients were stratified into training(n=1,665)and validation(n=715)cohorts.Five machine learning algorithms—Logistic regression(LR),artificial neural network(ANN),support vector machine(S VM),random forest(RF),and extreme gradient boosting(XGB)—were employed to construct predictive models.A nomogram was developed for clinical utility.Results Among 2,380 patients,226(9.5％)developed PPI.The Least Absolute Shrinkage and Se-lection Operator(LASSO)regression identified eight predictive variables:daily cigarette consumption,diabetes history,preoperative diffusing capacity,maximal tumor diameter,24-hour postoperative chest drainage volume,perioperative oral nutritional supplementation(ONS),postoperative urinary cathe-terization,and intraoperative pleural adhesion severity.All models demonstrated robust discrimina-tion,with area under the curve(AUC)values ranging from 0.862 to 0.947.The XGB model a-chieved superior performance(AUC=0.947,95％CI,0.937 to 0.962),followed closely by the LR model(AUC=0.926,95％CI,0.918 to 0.933).Conclusion Machine learning-based algo-rithms models effectively stratify PPI risk in lung cancer patients following grade Ⅳ thoracoscopic surgery.The derived nomogram provides a practical tool for perioperative risk management by healthcare providers.

Objective To construct a health management information service platform for glaucoma patients to achieve continuous care.Methods The architecture of the health management information service platform for glaucoma patients was designed,and the platform was developed and implemented.Results A WeChat mini program-based health management information service platform was developed,consisting of a medical staff interface,a patient interface,and a backend management center.The platform integrates functions such as whole-process disease tracking,surgical management,medication and follow-up record-keeping with reminders,communication for follow-ups,and health education.From March 2021 to March 2024,the platform registered 2764 patients and 45 medical staff,with a total of 10 947 platform interactions.An overall assessment with the post-study system usability questionnaire yielded a mean score of 28.2,indicating good user experience.Conclusion This platform realizes closed-loop management for continuous care of glaucoma patients and provides a practical reference for the development and exploration of health management information service platforms.

Objective To investigate the characteristics of cognitive inhibition in children with hearing impairment and the impact of different types of materials on their cognitive inhibition.Methods From June,2024 to January,2025,21 children with hearing impairment from Liaocheng Special Education School and 20 typically developing children from Guotun Town Central Primary School in Yanggu County,Liao-cheng were randomly selected.A directed forgetting task was used in a mixed experimental design.The experi-mental procedure was presented using Eprime 3.0,and recall performance was recorded through paper-and-pen-cil tests.Results Three children with hearing impairment and two typically developing children were dropped down.The children with hearing impairment scored significantly lower on recall tasks than the typically developing children(F=13.545,P<0.001).In the typically developing children,recall performance under the memory condition was sig-nificantly lower than under the forgetting condition(P<0.001).In the children with hearing impairment,there was no significant difference in recall performance between the memory condition and the forgetting condition(P>0.05).Regardless of whether the materials were letters or figures,all the children showed significantly high-er recall scores under the forgetting condition compared to the memory condition(P<0.01).Conclusion Children with hearing impairment exhibit weaker cognitive inhibition compared to typically developing chil-dren.The type of materials doesn't impact individuals'cognitive inhibition performance.

Purpose To analyse the expression of aldo-keto reductase AKR1C3 in the tumour tissues of oral squa-mous carcinoma(OSCC)and the correlation of clinical prognosis of patients.Methods Immunohistochemical(IHC)staining was performed to analyze the expression characteristics of AKR1C3 in 86 cases of OSCC tumor tissues and paired paratumor normal tissue.The correlation between AKR1C3 expression and clinical prognosis was evaluated.Ka-plan-Meier survival analysis was conducted to assess the survival outcomes of OSCC patients.Univariate and multivari-ate Cox regression analyses were employed to identify prognostic factors.The findings were further validated by compar-ison with the Cancer Genome Atlas(TCGA)database.Results The expression of AKR1C3 was significantly higher in OSCC tumor tissues than in paratumor normal tissue,with higher expression observed at the invasive front relative to the tumor centers.Immunohistochemical analysis revealed high expression in both tumor cells and tumor-associated fibro-blasts,while no expression was detected in tumor-infiltrating immunocytes.The x2 test was used to compare the rela-tionship between different expression levels of AKR1C3 and clinicopathological features in OSCC,the results showed that high expression of AKR1C3 was strongly associated with higher tumour stage(P=0.001),lymph node metastasis(P=0.023),differentiation(P=0.018),worst pattern of invasion(P=0.024)and depth of invasion(P=0.012).Kaplan-Meier survival curve analysis showed high expression of AKR1C3 was associated with overall survival(P=0.004),disease-free survival(P=0.019),and metastasis-free survival(P=0.05)in OSCC patients.Cox re-gression model was performed for prognostic analysis.Univariate analysis showed that high expression of AKR1C3 in tumour cells was a high-risk factor for patients' tumour stage(P＜0.001),lymph node metastasis(P＜0.001),dif-ferentiation(P＜0.001),worst pattern of invasion(P＜0.001),depth of invasion(P＜0.001).Multivariate analy-sis further showed that high expression of AKR1C3 in tumour cells was an independent prognostic factor in OSCC pa-tients(P=0.025).Conclusion The AKR1C3 expression is closely related to the prognosis of OSCC patients,and patients with high AKR1C3 expression have a poor prognosis,suggesting that AKR1C3 plays an important role in the occurrence and development of OSCC.

Objective:To systematically evaluate the impact of internet-based patient decision aid (PtDA) on decision-making for prenatal screening and diagnosis among pregnant women.Methods:Randomized controlled trials (RCTs) on the application of internet-based PtDA for prenatal screening and diagnosis among pregnant women were searched in PubMed, Embase, Web of Science, CINAHL, Cochrane Library, China National Knowledge Infrastructure, Wanfang Date, VIP, and China Biology Medicine disc. The search period was from inception to August 11, 2024. Two researchers independently screened the literature, extracted data, and assessed the quality of included studies. Meta-analysis was performed using RevMan 5.4 software.Results:A total of 10 studies involving 3 838 pregnant women were included. The meta-analysis showed that internet-based PtDA significantly reduced decision conflict ( P<0.05), improved decision knowledge ( P<0.01), and decreased decision anxiety ( P<0.05) among pregnant women but had no significant impact on decision regret ( P>0.05) . Conclusions:Internet-based PtDA effectively reduce decision conflict and anxiety while improving decision knowledge during prenatal screening and diagnostic decision-making. Future studies should focus on developing culturally appropriate decision aids tailored to the Chinese context and explore the enhanced role of nurses in prenatal screening counseling.
