Objective To understand the characteristics and trends of occupational diseases in Taicang City,provide reference for formulating occupational disease prevention and control strategies. Methods The new occupational disease cases from January 1,2006 to December 31,2023 were derived from the "China Disease Prevention and Control Information System,Occupational Disease and Health Hazard Monitoring Information System",and the data were analyzed. Results From 2006 to 2023,there were 185 new cases（7 categories,27 kinds） of occupational diseases in Taicang City. The overall incidence of occupational diseases was on the rise. The top three new cases of disease were occupational otorhinolaryngology and oral diseases（34.05%）,pneumoconiosis and other respiratory diseases（31.89%）,and occupational chemical poisoning（26.49%）. The male to female ratio of new cases was 4.14 ∶ 1. The average age of onset was 44.94 years old,and the median length of service was 6.08 years. The new cases were mainly found in the manufacturing industry（97.30%）,the enterprise scale was mainly small（63.24%） and medium（30.81%） types,and the economic type was mainly domestic enterprises（62.16%）. Conclusions The incidence of occupational diseases in Taicang City from 2006 to 2023 is on the rise,and occupational otorhinolaryngology and oral diseases have become a new challenge. In Taicang City,it is necessary to strengthen the prevention and control of occupational diseases in small and medium-sized domestic manufacturing enterprises,with a focus on non-metallic mineral products,metal products,rubber and plastic products in the manufacturing industry. The occupational chemical poisoning is in a low state in recent years,but it is still necessary to prevent the occurrence of acute collective poisoning.

Objective To analyze the characteristics,trends and regularities of pneumoconiosis in a district of Tianjin,understand the health status and security status of patients with pneumoconiosis,so as to provide a basis for formulating the protection policy for pneumoconiosis patients in the district. Methods A follow-up and retrospective survey was conducted on 1 780 pneumoconiosis patients reported in a district of Tianjin by the end of 2022,and a descriptive analysis was performed on the age at onset,dust exposure time,gender,types of pneumoconiosis,industry distribution,and social security coverage among pneumoconiosis patients. Results Totally 1 780 patients were included in the present study. The differences in genders and stages of pneumoconiosis were statistically significant（all P<0.01）. There were statistically significant differences in different age,dust exposure time,and stages of pneumoconiosis（all P<0.01）. The number of patients with asbestosis and foundry pneumoconiosis was the largest,which were 1 005 cases（6.46%） and 614 cases（28.88%）,respectively. The number of new pneumoconiosis cases reached two peaks in the "Eighth Five-Year Plan" and "Twelfth Five-Year Plan" periods,which were 298 cases and 341 cases,respectively. Among the 1 704 surviving patients,there were statistically significant differences in age distribution and working age distribution between sex groups（χ²=18.442,45.884,both P<0.01）. There were statistically significant differences in the benefits of work-related injury insurance,employer compensation,and basic medical insurance among different types,sizes,and categories of enterprises（all P<0.05）. Conclusion The prevention and control of pneumoconiosis in a district of Tianjin has made remarkable progress and results,but the prevention and control situation is still grim,so further attention should be paid to graded diagnosis and treatment on the basis of strengthening supervision,and the social security measures should be increased,to improve the quality of life of patients in the future.

Objective To identify the occupational hazards existing in workplace in the polymetallic mining construction project,understand the current situation of occupational hazards in small metal mines,evaluate the exposure level of operators exposed to occupational hazards,and put forward feasible occupational hazard control measures and countermeasures. Methods In June 2023,the staff of Qinghai Coal Mining Design and Research Institute Limited Liability Company（QCDRI） used the occupational health survey method and occupational health testing method to comprehensively evaluate the occupational hazards in the workplace of a polymetallic mining construction project in Dulan County of Qinghai Province. Results During the drilling operation of the driller in the underground working face,the time-weighted average concentration of silica dust exposure was 2.60 mg/m³,the 40 h equivalent sound level intensity of noise exposure was 105.4 dB（A）,and the 4 h frequency weighted vibration acceleration value of the contacted hand-transmitted vibration was 8.6 m/s²,which exceeded the requirements of the occupational exposure limit value. The concentration（intensity） of the other job exposure to occupational hazards factors met the requirements of the occupational exposure limit value. Conclusions The metal mine workplaces have a poor environment and are prone to occupational hazards,especially in the drilling work process where the concentration（strength） of exposure to occupational disease hazards seriously exceeds the standard. After the construction project is put into operation,the employer should take measures such as reforming the process,prioritizing equipment,and optimizing the occupational disease protection facilities for the drilling workplaces in the underground,in order to mitigate the impact of occupational disease hazards on workers' health generated during the production process. At the same time,it should set up occupational hazards and protection signs in the workplaces,equip workers with effective personal protective equipment,provide occupational hygiene training for workers,take regular workplace monitoring,occupational health surveillance and other actions to strengthen management,and it is expected that,during the normal operation of the construction project,it will be possible to effectively control occupational disease hazards and prevent occupational diseases,and to achieve the goal of protecting workers' health.

Objective To explore the application of semi-quantitative risk assessment contact index method in the pre-assessment of occupational hazards by identifying the occupational hazard factors in the production process of the delayed closed decoking technology transformation project of a petrochemical company in Karamay City. Methods In December 2023,a semi-quantitative risk assessment model was established with reference to the Technical guidelines for occupational health risk assessment of chemical harmful factors in the workplace（GBZ/T 298-2017） and the Catalogue of highly toxic substances. Combined with the toxicity of chemical harmful factors in GBZ/T 298-2017 appendix Table F.1 and Table F.2,the hazard characteristics were evaluated and graded respectively,and the exposure index method was used to determine the risk level. Results The test results of the main occupational hazard factors of the existing delayed coking decoking equipment showed that the concentration of coke dust was 0.2-1.36 mg/m³,the concentration of hydrogen sulfide was <0.53 mg/m³,the concentration of solvent gasoline was <0.44-0.20 mg/m³,and the noise intensity of each position was 76.0-83.1 dB（A）. The occupational hazards caused by coke dust,hydrogen sulfide,solvent gasoline,benzene,toluene,xylene,liquefied petroleum gas,and sodium hydroxide used in the process of exhaust gas desulfurization in the proposed project were all at low risk level（risk index R=2）. The risk of occupational hazards caused by hydrogen sulfide exposed to non-coke and non-coke operation is moderate（risk index R=3）. Conclusion The semi-quantitative risk assessment contact index method can be used in the pre-assessment of occupational hazards in the absence of analog detection data,and can better predict and assess the occupational hazards risk level in the production process,so it has been applied in the closed de-coking pre-assessment in the petrochemical industry,making up for the shortcomings of the analogue assessment method.

Objective To use network pharmacology methods to explore the potential molecular mechanisms of Weiling Tang in the treatment of non-alcoholic fatty liver disease（NAFLD）,in order to provide new ideas for research. Methods The pharmacological substance basis and targets of Weiling Tang were obtained by using the traditional Chinese medicine system pharmacology database and analysis techniques. On this basis,the common targets of "disease-drug" were input into the database,and a "protein-protein" interaction network was established to achieve a network graph of "drug-active ingredients-common targets-disease" and analyze its topological relationship. And the biological activity screening was conducted on common targets,activity pathway analysis was performed on common targets on the combination of enrichment technology of the Kyoto Encyclopedia of Genes and Genomes. Results In the preliminary work,239 effective components of Weiling Tang and 979 targets related to NAFLD have been obtained,and 115 common active ingredient disease targets have been discovered. The previous research found that there is protein kinases closely related to the development of NAFLD. GO enrichment analysis included biological processes such as signaling pathways and intercellular communication. KEGG enrichment analysis mainly involved tumor pathway,lipid and atherosclerosis,cytomegalovirus infection,and Kaposi sarcoma with herpes virus infection. Conclusion Weiling Tang may treat non-alcoholic fatty liver through multiple components,targets,and pathways,providing important basis for in-depth research on related molecular mechanisms.

Objective To explore the evaluation method for estimating the biological dose of chromosomal aberrations in peripheral blood lymphocytes,objectively evaluate the laboratory testing ability,and promote the improvement of testing level. Methods Based on the data submitted by the national participating laboratories in 2023,analyze the problems of existing evaluation methods,and study and improve methods that can objectively evaluate laboratory testing capabilities. Results According to the radiation doses of 1.6,2.7,and 3.7 Gy,the Z-score evaluation method showed that the pass rate of the A categories 3.7 Gy group was lower than that of the deviation evaluation method,while the pass rates of other groups were higher than that of the deviation evaluation method. There were no statistically significant difference in the pass rate between the two evaluation methods in A categories 2.7 Gy group and 3.7 Gy group（both P>0.05）,while there was statistically significant difference in other groups（all P<0.05）. The average estimated dose reported by each group was lower than the irradiation dose,indicating a negative deviation. Except for the B categories 1.6 Gy group,which had a relatively small relative irradiation dose deviation（-1.88%）,the deviation of the other groups ranged from -11.48% to -20.54%,and the variation level ranged from 12.63% to 20.81%. The estimated average value of laboratories using self-constructed curves was slightly higher than that of laboratories using national standard recommended curves,but the difference was not statistically significant（P>0.05）. Using the estimated mean value of each group as the target value and using the probability t to determine the allowable error range can conveniently evaluate the testing ability of the participating laboratories. Conclusion The existing evaluation methods have not consider the characteristics of this test and the actual situation of participating laboratories uniformly,and needs to be gradually improved in terms of determining target values and allowable error ranges in combination with specific circumstances.

Objective To understand the relationship between work pressure,coping style and mental health of workers in Baoji City,provide scientific evidence for formulating relevant policies and measures. Methods From August to November in 2023,a survey was conducted among 690 workers in Baoji City using self-designed general demographic data questionnaire,Kessler10 simplified psychological status rating scale,occupational stress indicator questionnaire and simplified coping style questionnaire,and the data were analyzed. Results The Kessler10 score of 690 workers in Baoji City was （20.26±7.84）points,and 74.5% had a lower risk of psychological illness（K10 total score ≤24 points）. The average score of the occupational stress indicator questionnaire was （85.28±29.37）points. 98% of workers tended to adopt positive coping styles. The coping style is negatively correlated with mental health（r=-0.304,P<0.01）,while work pressure was positively correlated with mental health（r=0.373,P<0.01）,and work pressure was negatively correlated with coping style（r=-0.231,P<0.01）. The coping style played a partial mediating role between work pressure and mental health status. The indirect effect value of work pressure on mental health status through coping style was 0.053（β=-0.230,t=-6.503,P<0.01）. Conclusions The work pressure is positively correlated with mental health,with higher work pressure leading to higher mental health scores and poorer mental health status. The work pressure is negatively correlated with coping styles,with higher work pressure leading to a greater tendency towards negative coping styles. By reducing work pressure and promoting positive coping of workers,it is possible to improve mental health levels.

Objective To explore the potential types and characteristic differences of alarm fatigue among nurses in intensive care unit（ICU）,and analyze the related influencing factors. Methods Convenience sampling was used to select 276 nurses from 3 kinds of ICUs（comprehensive ICU,neurosurgical ICU,emergency ICU） in 10 hospitals in Sichuan Province as the survey objects from January to May 2023. General information questionnaire,clinical alarm fatigue scale,depression anxiety stress scale（DASS-21） and the national aeronautics and space administration（NASA） mission compliance index were used to analyze the potential profile of alarm fatigue characteristics of ICU nurse. The influencing factors of the potential profile were identified by single factor analysis and logistic regression analysis. Results The total score of alarm fatigue scale of ICU nurses was（24.40±6.84）points,the total score of psychological load scale was （87.83±15.51）points,and the total score of negative emotion scale was 17.00（9.00,26.00）points. The alarm fatigue of ICU nurses could be divided into three potential profiles,namely,high fatigue-high stress group[78 individuals（28.26%）],moderate fatigue-low concentration group[134 individuals（48.55%）],mild fatigue-low mood group[64 individuals（23.19%）]. The results of unordered multi-classification logistic regression analysis showed that compared with moderate fatigue and low concentration group,stress（OR=1.260,P<0.05） and load perception（OR=1.137,P<0.01） were the predictors of high fatigue and high stress group,while anxiety（OR=0.775,P<0.05）,stress（OR=0.716,P<0.01）,provincial hospitals（OR=0.260,P<0.05） and working experience of 0-<5 years（OR=8.005,P<0.05） were the predictors of mild fatigue and low mood group. Conclusion The alarm fatigue characteristics of ICU nurses are heterogeneous and can be divided into 3 potential profiles. Nursing managers can individually intervene ICU nurses according to the influencing factors of different potential profiles to reduce alarm fatigue.

Objective To understand the particle size distribution characteristics of moxa smoke and the influencing factors of air quality in moxibustion diagnosis and treatment rooms. Methods From June to July 2023,an aerosol spectrometer was used to sample and analyze the moxa smoke generated by the burning of moxa columns during diagnosis and treatment in the moxibustion diagnosis and treatment room. Real time monitoring was conducted on the particle concentrations of four particle sizes：ultrafine particles,fine particles,inhalable particles,and total particles,and the results were analyzed. Results The particle size distribution of moxa smoke did not change with the changes of acupuncture position and the time of diagnosis and treatment. There was no significant difference in the concentration of particulate matter with different diameter（P>0.05）. The concentration of particulate matter with different particle sizes was related to burning time and ventilation mode,and decreases as the particulate matter concentration reaches its peak during moxibustion stick combustion. The peak ranges of ultrafine particles,fine particles,inhalable particles,and total particles were 664.75-1 774.35,681.17-1 991.25,728.63-2 468.61 and 737.93-2 572.72 μg/m³,respectively. Conclusion The air quality in the moxibustion diagnosis and treatment room is related to the ventilation mode of the treatment room. The smoke produced by the combustion of moxibustion stick is mainly composed of inhalable particles,especially fine particles and ultrafine particles.
