Objective: To explore the formulation patterns and potential targets of traditional Chinese medicine (TCM) in the treatment of pneumoconiosis using data mining, network pharmacology, and Mendelian randomization (MR) . Methods: In November 2023, prescription data for TCM compound treatments of pneumoconiosis from the past five years were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang, and VIP databases. The formulation patterns of TCM for pneumoconiosis were analyzed based on drug frequency, association rules, and cluster analysis, followed by the identification of core drugs. Network pharmacology and MR analysis were then applied to determine the potential targets for pneumoconiosis treatment. Results: A total of 100 TCM prescriptions were included, involving 182 herbs, with 15 high-frequency herbs. A total of 24 strong association rules were identified, including 16 herbs. Cluster analysis identified three groups of drug combinations. The core drug combination, "Astragalus Root-Codonopsis Root-Tangkuei-Chinese Magnolia Vine Fruit-Danshen Root-Prepared Rehmannia Root" was determined, which interacted with 47 common targets associated with pneumoconiosis. Further protein-protein interaction (PPI) analysis identified 18 core targets, and MR analysis confirmed that Caspase-3 (CASP3) and Cathepsin B (CTSB) were risk factors for pneumoconiosis (OR=1.35, 1.44; P=0.038, 0.038) . Conclusion: The core drug combination for the treatment of pneumoconiosis with TCM is "Astragalus Root-Codonopsis Root-Tangkuei-Chinese Magnolia Vine Fruit-Danshen Root-Prepared Rehmannia Root". The medication mainly focuses on tonifying lung qi, moistening dryness and stopping coughing, circulating blood and transforming stasis, which are supplemented with herbs for nourishing yin and moistening dryness, warming yang and dissipating cold. Finally, the key targets for treating pneumoconiosis are screened out, providing an important basis for the development of therapeutic drugs for it.

Objective: To explore the moderating and mediating roles of psychological resilience in the relationship between job satisfaction and depressive symptoms among petrochemical workers. Methods: In April 2022, a cluster sampling method was used to conduct a questionnaire survey among 1087 in-service employees of a petrochemical enterprise in Henan Province. A total of 861 questionnaires were recovered, including 857 valid ones, with an effective rate of 99.54%. Data on job satisfaction, psychological resilience, and depressive symptoms were collected using the 10-item Connor-Davidson Resilience Scale (CD-RISC-10), Job Satisfaction Questionnaire, and Patient Health Questionnaire-9 (PHQ-9). Spearman rank correlation analysis was applied to analyze the relationships among the scores of job satisfaction, psychological resilience, and depressive symptoms. Hierarchical linear regression analysis was used to test the moderating effect of psychological resilience, and the Bootstrap method was employed to verify the mediating effect of psychological resilience. Results: The scores of job satisfaction, psychological resilience, and depressive symptoms among petrochemical workers were 36.00 (31.00, 36.00) points, 36.00 (30.00, 41.00) points, and 7.00 (3.00, 9.00) points. The detection rate of depressive symptoms was 65.7% (563/857). Results of Spearman rank correlation analysis showed that job satisfaction of petrochemical workers was positively correlated with psychological resilience (r(s)=0.270, P<0.01) and negatively correlated with depressive symptoms (r(s)=-0.386, P<0.01), psychological resilience was negatively correlated with depressive symptoms (r(s)=-0.515, P<0.01). Results of hierarchical linear regression analysis indicated that psychological resilience had no moderating effect on the relationship between job satisfaction and depressive symptoms of petrochemical workers (b=0.001, P>0.05). Results of the mediating effect test showed that psychological resilience played a partial mediating effect in the relationship between job satisfaction and depressive symptoms (P<0.01), with a mediating effect value of -0.071 (95%CI: -0.125, -0.045), accounting for 20.16% of the total effect. Conclusion: Psychological resilience exerts a partial mediating effect rather than a moderating effect in the relationship between job satisfaction and depressive symptoms among petrochemical workers.

Objective: To investigate the temporal correlation between occupational stress and elevated blood pressure among petroleum workers in Xinjiang. Methods: Based on the Occupational Health Study Cohort of Petroleum Workers (OHSPIW), 1600 petroleum workers in Xinjiang who underwent occupational health examinations from May to June 2015 and December 2017 were selected as the research subjects. The occupational stress of workers was evaluated using the Occupational Roles Questionnaire (ORQ) in the Occupational Stress Inventory-Revised (OSI-R). The blood pressure measurement data of physical examination results were collected. The relationship between the ORQ total score and blood pressure was analyzed using Spearman rank correlation, and the causal time-series relationship between occupational stress and elevated blood pressure over time was analyzed by cross-lagged path analysis modelling. Results: In the baseline data of petroleum workers, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 124.00 (119.00, 128.00) and 77.00 (73.00, 82.00) mmHg respectively, with an ORQ total score of 164.00 (154.00, 174.00) points. In the follow-up data, the SBP and DBP were 126.00 (123.00, 128.00) and 78.00 (75.00, 82.00) mmHg respectively, and the ORQ total score was 168.00 (157.00, 181.00) points. The results of the correlation analysis showed that the ORQ total score of petroleum workers was positively correlated with the levels of SBP and DBP (P<0.05), and the ORQ total score at follow-up was negatively correlated with the baseline levels of SBP and DBP (P<0.05). The results of the cross-lagged path analysis showed that the path coefficients from the baseline ORQ total score of petroleum workers to the follow-up SBP and DBP levels were statistically significant (ρ=0.06, 0.06, P=0.032, 0.011). In terms of time sequence, the increase in the ORQ total score preceded the increase in the SBP and DBP levels. Conclusion: The occupational stress of petroleum workers is related to blood pressure, and the increase of occupational stress precedes the change of blood pressure. This correlation may increase the risk of hypertension among petroleum workers.

Automotive antifreeze, being colorless and odorless, can easily cause acute poisoning if ingested. Acute poisoning can lead to damage to the central nervous system, digestive system, and kidney function, and may even result in death. This article analyzes the clinical data, diagnostic and therapeutic processes, and outcomes of two patients admitted to the Department of Poisoning and Occupational Diseases, Emergency Medicine of Qilu Hospital, Shandong University, who suffered acute poisoning due to ingesting antifreeze. The findings aim to provide a reference for clinicians in the diagnosis and treatment of antifreeze poisoning.

Objective: To explore the research hotspots and trends in the literature related to hearing loss caused by organic solvents, and to provide an effective theoretical basis for further research on the impact of ototoxic organic solvents on the auditory system. Methods: In January 2024, literatures that met the inclusion/exclusion criteria from 1974 to 2023 in the PubMed database were selected. The authors, countries, journal fields and publishing institutions of the literatures were analyzed through Bicomb version 2.01. The author co-occurrence knowledge network graph and the literature publication institution graph were plotted using CiteSpace 6.3R1 Advance, and the co-occurrence clustering map of keywords was drawn using VOS viewer 1.6.19 software. Results: A total of 380 relevant literatures were retrieved, and 256 were finally included. The top three countries in terms of the number of published literature were the United States (accounting for 30.08%, 77/256), the United Kingdom (accounting for 17.97%, 46/256), and the Netherlands (accounting for 10.16%, 26/256). The published authors were represented by Pierre Campo, involving a total of 165 institutions, mainly occupational health research institutions and hearing institutions. It mainly involved related fields such as audiology, occupational medicine, environmental hygiene, toxicology, and otolaryngology. The key groups were painters, aviation industry personnel, gas station workers and agricultural workers. The key solvents included organic solvent mixtures, benzene and its derivatives, trichloroethylene, ethanol, carbon disulfide, etc. Conclusion: Research on hearing loss caused by organic solvents mainly focuses on countries such as the United States, the United Kingdom, and the Netherlands, with a particular emphasis on occupational groups such as painters, aviation industry personnel, gas station workers, and agricultural personnel, as well as the ototoxic effects of organic solvent mixtures, benzene and its derivatives, etc. This provides a basis for subsequent mechanism exploration, protection strategy formulation, and hearing health management of the target population.

Objective: To investigate the current situation of depressive symptoms, effort-reward imbalance (ERI), and sleep quality among train drivers, explore the interaction mechanism between various factors and depressive symptoms, and provide a certain theoretical basis for reducing the level of depressive symptoms among train drivers. Methods: From January to December 2022, train drivers were selected as the research subjects from the locomotive depot of a certain railway bureau through cluster sampling, with a total of 1392 people. A questionnaire survey was conducted to assess the basic situation, ERI, sleep quality and depressive symptoms of train drivers. Multiple stepwise regression was used to analyze the effects of each dimension of ERI and sleep quality on depressive symptoms, and binary logistic regression was used to analyze the effects of ERI and sleep quality on depressive symptoms. Results: Among 1392 train drivers, 897 (64.4%) were classified as having depressive symptoms. The results of multiple stepwise regression analysis showed that the dimensions of external effort, reward and overcommitment of ERI explained 10.3% of the variation in depressive symptoms (P<0.01). Sleep quality explained 9.9% of the variation in depressive symptoms (P< 0.01). The results of binary logistic regression analysis showed that after adjusting for confounding variables such as age, length of service, and educational level, high external effort (OR=2.22, 95%CI: 1.76-2.79) and high overcommitment (OR=1.90, 95%CI: 1.50-2.39) and poor sleep quality (OR=5.82, 95%CI: 4.52-7.49) increased the risk of depressive symptoms for train drivers (P<0.01), while reward was a protective factor for depressive symptoms (OR=0.44, 95%CI: 0.35-0.55, P<0.01). In the ERI model, high effort and low reward was the greatest risk factor for depressive symptoms (OR=4.77, 95%CI: 3.41-6.69, P<0.01). In the interaction between ERI and sleep quality, high ERI and poor sleep quality had the greatest negative impact on depressive symptoms (OR=15.90, 95% CI: 7.27-34.76, P<0.01) . Conclusion: The influence of ERI on depressive symptoms of train drivers has both direct and indirect effects, and sleep quality plays a partial mediating role in the influence of ERI on depressive symptoms.

Objective: To verify the reliability and validity of the short version of the Chinese version of the new Burnout Assessment Tool (12 items version of Burnout Assessment Tool, BAT-12) . Methods: From October to December 2023, the cluster sampling method was adopted, and the Chinese version of the Maslach Burnout Inventory-General Survey (MBI-GS) and the BAT-12 scale were used simultaneously. A questionnaire survey was conducted among enterprise employees (4329 people) in Shanghai and Guangdong Province. Exploratory factor analysis and confirmatory factor analysis and other methods were employed to analyze its reliability (internal consistency reliability and combination reliability) and validity (structural validity, convergent validity, discriminative validity and criterion validity) . Results: A total of 4329 questionnaires were retrieved, among which 4086 were valid, with an effective recovery rate of 94.39%. The Cronbach's α coefficient of the Chinese version of the BAT-12 total scale was 0.956, and the combination reliability coefficients of each dimension ranged from 0.914 to 0.952. The scale contained 12 items, and 4 common factors were extracted from exploratory factor analysis, including exhaustion, mental distance, cognitive impairment, and emotional impairment. The cumulative variance contribution rate reached 86.63%. Confirmatory factor analysis showed that both the four-factor correlation model and the second-order model were ideally fitted overall, with the four-factor correlation model having the best data fit (comparative fit index 0.972, Tuker-Lewis fit index 0.962, root mean square error of approximation 0.064, and standardized root mean square residual 0.033). The average variance extracted (AVE) of each dimension of the scale ranged from 0.780 to 0.868, and the square roots of AVE (0.883 to 0.932) were all greater than their Pearson correlation coefficients (0.630 to 0.850). The Pearson correlation coefficient between BAT-12 and MBI-GS was 0.787 (P<0.001) . Conclusion: The Chinese version of the BAT-12 scale demonstrates strong internal consistency and combination reliability, with excellent reliability. Its four-dimensional structure validity has been validated, with good convergent validity, discriminative validity, and ideal criterion validity, demonstrating excellent validity. The Chinese version of the BAT-12 scale can be used to measure the level of occupational burnout among Chinese employees.

Objective: To investigate the subacute toxicity and target organs of triethylenediammonium perchlorate ammonium complex salt (DAP-4) . Methods: In August 2024, 40 SPF-grade SD rats were selected, with 10 rats in each group, half male and half female. There were 45, 140, and 420 mg/kg DAP-4 groups and a control group. Rats in each dose DAP-4 group were orally administered the corresponding amount of DAP-4 solution, while the control group was given the same dose of 1% sodium carboxymethyl cellulose. SD rats were given intragastric administration once a day for 28 consecutive days. The behaviors, histopathological changes, and blood physiological and biochemical indicators of rats were detected at the corresponding time points respectively. One-way analysis of variance was used for the comparison of quantitative data between groups. Results: Compared with the control group, the body weight, food intake and food utilization rate of female and male rats in the 420 mg/kg DAP-4 group were significantly decreased (P<0.05), while no abnormalities were observed in the other dose groups. Compared with the control group, the white blood cell count of female rats in the 420 mg/kg DAP-4 group decreased, while the hemoglobin and hematocrit decreased and the total serum protein increased of male rats (P<0.05). Compared with the control group, fibrinogen was increased in both female and male rats in the 420 mg/kg DAP-4 group, and the thrombin time of female rats was shortened (P<0.05). In each dose group, the livers of female and male rats showed varying degrees of vacuolar degeneration, and the renal tubules of female rats were swollen. Conclusion: 420 mg/kg DAP-4 can cause damage to the liver and kidney of rats, and the maximal no effect level of DAP-4 for rats is 140 mg/kg.
