Background Health literacy is closely related to mental health, and improving health literacy has been shown to promote mental well-being. However, whether occupational stress among workers in mining and manufacturing is associated with their occupational health literacy remains inconclusive. Objective To study the levels of occupational health literacy and occupational stress among workers in three industrial sectors (metal ores mining, metal smelting, and manufacture of non-metallic mineral products) in Gansu Province, and to analyze the correlation between them. Methods Between May and December 2024, a stratified cluster random sampling method was employed to survey workers from 73 large, medium, and small and micro sized enterprises across the aforementioned industries in Gansu Province. Participants’ occupational health literacy and occupational stress levels were assessed. The LASSO regression model was applied to identifykey factors influencing occupational stress, and subsequently a multilevel random intercept mixed-effects logistic model was used to study factors influencing occupational stress and to explore the relationship between occupational health literacy and occupational stress. Results A total of 3611 workers across the three industries were surveyed, among whom 1031 (28.55%) experienced occupational stress. Workers with adequate occupational health literacy—whether assessed in terms of overall literacy or specific dimensions—demonstrated a significantly lower prevalence of occupational stress compared to those without adequate literacy (P<0.05). Through the LASSO regression analysis, it was found that the factors closely related to occupational stress were dimension one (occupational health legal knowledge), dimension two (basic knowledge of occupational health protection), and dimension four (healthy working methods and behaviors) of occupational health literacy, gender, average monthly income, and night shifts. The results from the three-level random intercept mixed-effects logistic regression model indicated that dimensions one (OR=0.69, 95%CI: 0.58, 0.82), two (OR=0.71, 95%CI: 0.58, 0.87), and four (OR=0.81, 95%CI: 0.67, 0.98) of occupational health literacy were negatively correlated with the risk of occupational stress. Workers with an average monthly income of 3001–≤5000, 5001–≤7000, and ≥7001 yuan reported occupational stress risks that were 61% (OR=0.61, 95%CI: 0.45, 0.81), 56% (OR=0.56, 95%CI: 0.41, 0.78), and 36% (OR=0.36, 95%CI: 0.24, 0.53) of those with an average monthly income ≤3000 yuan, respectively. Male workers (OR=1.66, 95%CI: 1.32, 2.10) and those on night shifts (OR=2.29, 95%CI: 1.90, 2.76) had a higher risk of occupational stress. The random effects variance showed that the intraclass correlation coefficient was 0.12. Conclusion There is a negative correlation between occupational stress and occupational health literacy among workers in mining and manufacturing. Being male, having a low income, and working night shifts are risk factors affecting workers' occupational stress. It is recommended to focus on these groups of workers and incorporate occupational health literacy into workplace mental health promotion.

Objective:To investigate the effect of preoperative systemic inflammatory response index (SIRI) on prognosis in patients with resectable colorectal cancer.Methods:The clinical data of 355 colorectal cancer patients underwent radical resection from January 2018 to December 2022 in the Second Affiliated Hospital of Harbin Medical University were retrospectively analyzed. The basic information, pathological data and laboratory test results were recorded, and SIRI was calculated. The patients followed up to December 2023 or death, and the overall survival (OS) and disease-free survival (DFS) were recorded. The receiver operating characteristic (ROC) curve was drawn, the optimal critical value of SIRI in patients with colorectal cancer was determined according to the maximum Yoden index, and the patients were grouped based on this. Multivariate Cox regression analysis was used to analyze the independent risk factors of prognosis in patients with colorectal cancer. Kaplan-Meier survival curve was drawn, and the log-rank test was used for comparison.Results:ROC curve analysis result showed that the optimal critical value of SIRI was 0.99, and the area under the curve was 0.556. Among the 355 patients with colorectal cancer, SIRI<0.99 was in 229 cases (low SIRI group), and SIRI≥0.99 was in 126 cases (high SIRI group). There were no statistical difference in gender composition, age, body mass index (BMI), preoperative carcinoembryonic antigen, preoperative cancer antigen 19-9 (CA19-9), tumor location, T stage, N stage, tumor stage, degree of differentiation, tumor long diameter, lymphatic invasion, vascular invasion, operating time and intraoperative blood loss between two groups ( P>0.05). The incidence of anastomotic leakage in high SIRI group was significantly higher than that in low SIRI group: 20.6% (26/126) vs. 12.2% (28/229), and there was statistical difference ( P<0.05). The median follow-up time of 355 patients was 21.7 months. The mortality and recurrence rate in high SIRI group were significantly higher than those in low SIRI group: 28.6% (36/126) vs. 19.2% (44/229) and 13.5% (17/126) vs. 6.1% (14/229), and there were statistical differences ( P<0.05). Kaplan-Meier survival curve analysis result showed that the median OS and DFS in high SIRI group were significantly lower than those in low SIRI group (17.3 months vs. 23.3 months and 15.1 months vs. 21.9 months), and there were statistical differences ( P<0.05). Multivariate Cox regression analysis result showed that the tumor stage Ⅲ to Ⅳ, preoperative CEA>5 μg/L and SIRI>0.99 were independent risk factors of OS and DFS in patients with colorectal cancer (OS: HR = 2.447, 1.951 and 1.923; 95% CI 1.461 to 4.099, 1.266 to 3.456 and 1.003 to 2.655; P<0.05. DFS: HR = 2.982, 1.782 and 1.529; 95% CI 1.663 to 4.754, 1.147 to 2.651 and 1.198 to 2.021; P<0.05). Conclusions:The preoperative SIRI is an independent risk factor of prognosis in patients with colorectal cancer. The patients with low SIRI have longer postoperative OS and DFS. The preoperative SIRI has guiding value in the prognosis assessment and treatment selection in patients with colorectal cancer.

Alzheimer's disease(AD)is an age-related neurodegenerative disease with an increasing incidence worldwide.A large number of studies have shown that the incidence rates of hearing loss is high in patients with mild cognitive impairment and Alzheimer's disease,and may be a risk factor for the occurrence and development of cognitive impairment.There is an interaction between the two,but the causal mechanism is still unclear.Early screening and management of hearing impairment may play an important role in the early diagnosis,symptom im-provement and disease progression of Alzheimer's disease.This paper reviews relevant clinical and basic research to discuss the correlation between hearing loss and Alzheimer's disease,and the possible causal mechanism between them.

Chronic kidney disease(CKD)is a major global health threat owing to its progressive nature and limited means of early diagnosis,with a significant majority of patients diagnosed in the mid-to-late stages of the disease and high mortality rates.With recent advancements in technology,the importance of disease prediction models in the management of CKD has increased.Disease incidence risk prediction models can identify high-risk groups at an early stage and provide support for timely intervention and management.These disease prognosis models can accurately assess the risk of future adverse events and optimize management strategies for patients.The aim of this review is to discuss the progress of disease prediction models in assessing the occurrence and prognosis of CKD and explore their potential for improving the early diagnosis of the disease,optimizing treatment,and improving patient prognosis.These advancements would assist in effectively preventing and treating CKD as well as improving treatment efficacy and quality of life of patients.

Objective To explore the application value of the deep learning image reconstruction algorithm(ClearInfinity,CI)combined with high tube voltage and low tube current low-dose computed tomography(LDCT)in lung screening.Methods A total of 216 patients underwent lung screening CT plain scan were selected.Patients were randomly divided into conventional-dose group(A group)and low-dose group(B group).Image reconstructed by using the iterative algorithm(ClearView+,CV)in group A,CV-60％,CI-30％,CI-60％,and CI-90％algorithms in group B.CT value,noise,image quality,and edge detail were conducted with both objective and subjective evaluations.Lung nodules were automatically detected by using computer-aided diagnosis software,and radiation doses were recorded.Results Images reconstructed with the CI showed significantly superior signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)than with the CV(P＜0.05).Additionally,there was a significant correlation in lung nodule detection performance between the CI and the CV(P＜0.05).The effective dose(ED)in group B was reduced by approximately 85.80％compared to group A(P＜0.01).Although the SNR and CNR were highest with CI-90％,the subjective image quality was lower than that of CI-60％.CI-60％and CI-90％showed same performance in lung nodule detection using artificial intelligence(AI)software.Conclusion The application of LDCT scanning protocol using the CI algorithm based on deep learning,combined with high tube voltage and low tube current is feasible for lung screening.It is recommended to use CI-60％in clinical diagnosis to improve the safety and diagnostic confidence of lung CT screening.

Objective:To observe the effectiveness of extracorporeal counterpulsation therapy in patients with heart failure in ischaemic cardiomyopathy.Methods:A total of 112 patients with ischemic cardiomyopathy and heart failure admitted to the Second Affiliated Hospital of Xingtai Medical College from August 2020 to June 2023 were prospectively selected and divided into two groups by random number table method. The control group was treated with conventional drugs and conventional cardiac rehabilitation program, and the observation group was combined with external counterbeating therapy on the basis of the control group. The levels of N-terminal B-type brain natriuretic peptide (NTproBNP), soluble growth stimulation-expression gene-2 protein (sST2), neutrophil gelatinase-associated lipid carrier protein (NGAL), galactin-3 (Gal-3), cardiopulmonary exercise test (CPET) parameters and cardiac ultrasound indexes were compared between the two groups before and after treatment. The curative effect and the rate of re-hospitalization within 6 months were compared between the two groups.Results:After treatment, the levels of NTproBNP, sST2, NGAL and Gal-3 in the observation group were lower than those in the control group: (1941.36 ± 312.59) ng/L vs. (2674.22 ± 404.64) ng/L, (44.78 ± 3.97) ng/L vs. (52.45 ± 4.13) ng/L, (22.63 ± 3.65) μg/L vs. (26.41 ± 3.77) μg/L, (4.63 ± 1.29) ng/L vs. (6.11 ± 1.78) ng/L, there were statistical differences ( P<0.05); the maximum kilogram oxygen uptake (VO 2max/kg), maximum kilogram oxygen uptake as a percentage of predicted value (VO 2max/kg%pred), maximum minute ventilation as a percentage of predicted value (VEmax%pred) in the observation group were higher than those in the control group: (22.41 ± 2.23) ml/(min·kg) vs. (21.35 ± 2.09) ml/(min·kg), (83.79 ± 11.04)% vs. (78.74 ± 10.14)%, (88.95 ± 12.74)% vs. (75.45 ± 11.14)%, there were statistical differences ( P<0.05 or <0.01); the left ventricular ejection fraction (LVEF) in the observation group was higher than that in the control group and the left ventricular posterior wall thickness (LVPWT) and left ventricular posterior wall end-systolic thickness (PWS) were lower than those in the control group: (50.12 ± 3.87)% vs. (48.63 ± 3.74)%, (8.77 ± 1.58) mm vs. (9.63 ± 1.97) mm, (9.34 ± 1.54) mm vs. (10.14 ± 1.79) mm, there were statistical differences ( P<0.05). There was no statistical difference in the total effective rate between the two groups ( P>0.05). The patient readmission rate within 6 months of follow-up in the observation group was lower than that in the control group: 5.45%(3/55) vs. 20.00%(11/55), there was statistical difference( χ2 = 5.24, P<0.05). Conclusions:Extracorporeal counterpulsation therapy for the treatment of heart failure in ischaemic cardiomyopathy can improve the cardiorespiratory function, reduce the expression of NTproBNP, sST2, NGAL and Gal-3, and decrease the patient readmission rate.
