Objective To investigate the current situation of the pre-hospital emergency personnel workforce in Shanghai,analyze the factors related to personnel job satisfaction in the pre-hospital emergency system and its relationship with work pressure and burnout,and put forward targeted recommendations and measures. Methods The current work status of the pre-hospital emergency personnel workforce in Shanghai was investigated from July to August 2022,and a cross-sectional survey was conducted on emergency-related personnel in all urban-level medical emergency centres in the city（a total of 10） using a basic information questionnaire,a job satisfaction scale,a job stress scale,and a burnout scale. A structural equation model was constructed to analyze the relationship between job satisfaction,work pressure and burnout among the pre-hospital emergency personnel in Shanghai. Results The job satisfaction score of pre-hospital emergency related personnel in Shanghai was （70.82±16.53）points,the job stress score was （24.25±6.10）points,and burnout score was （40.15±18.00）points,which were all above the medium level.The standardized path coefficient between job satisfaction and burnout among pre-hospital emergency personnel in Shanghai was -0.71,and the two were negatively correlated. The standardized path coefficient between job stress and job satisfaction was 0.88,indicating a positive correlation between the two.Job stress indirectly had a negative effect on burnout through the mediating role of job satisfaction. Conclusion Job satisfaction,as a mediator factor between job stress and burnout,suggests that we need to pay more attention to the needs and development pain points of pre-hospital emergency personnel,improve the working environment through the intelligent construction of the pre-hospital emergency system,focus on cultivating and upgrading the pre-hospital emergency personnel's own ability,improve performance evaluation,optimise the salary system,and stimulate innovation and creativity,which can reduce the job stress and burnout,and improve the job satisfaction of the pre-hospital emergency personnel,and effectively promote the high-quality and sustainable construction of pre-hospital emergency teams.

Objective To evaluate the uncertainty of tartrazine measurement results of quality control samples and blind samples in capability verification using high performance liquid chromatography,identify the main influencing factors of uncertainty,and provide reference for improving the reliability and accuracy of detection results. Methods Referring to GB 5009.35-2016 "National Food Safety Standard-Determination of Synthetic Colorants in Food",the pre-treatment method was optimized,enrichment and purification by solid-phase extraction column（SPE）,the sample was determined by constant volume and filter. According to JJF 1059.1-2012 "Evaluation and Expression of Measurement Uncertainty",the sources of uncertainty of the determination of tartrazine content in fruit juice were analyzed,including instrument,standard substances and sample pretreatment. By establishing a mathematical model and calculating the uncertainty components,the synthetic standard uncertainty and extended uncertainty were given. Results The determination of quality control samples was within the allowable error range of the specified value. According to the confidence interval of 95%,the extended uncertainties for the measured of tartrazine content in samples G and E were 5.31 and 3.88 μg/kg（k=2）. Conclusion The sources of uncertainty in the determination of tartrazine content in fruit juice mainly come from the preparation process of standard solutions and the repeatability of liquid chromatography. PWAX SPE columns can be used for sample pr-treatment,and regular periodic checks and instrument maintenance can be carried out to reduce the level of uncertainty.

Objective To analyze the clinical verifications of the feasibility evaluation system for vaccination of convalescent children with hematologic malignancies,and provide reference for vaccination of convalescent children with hematologic malignancies. Methods A modified Delphi and analytic hierarchy process were used to construct a feasibility evaluation system for vaccination of convalescent children with hematologic malignancies. Clinical demonstration was carried out by randomly select convalescent children with hematologic malignancies who visited the vaccine evaluation clinic of Shanghai Children's Medical Center from December 2022 to July 2023. The consistency between the evaluation opinions of clinical medical staff and the feasibility evaluation system for vaccination was analyzed. Results After two rounds of Delphi expert consultation,the expert authority degree（Cr） in both rounds was ≥0.70,the positive coefficient of experts was 100%,and the consistency of expert opinions was good（P<0.01）.The final determination of the feasibility evaluation system for vaccination includes 56 items,including 3 dimensions（clinical laboratory,physiological and basic information indicators,and disease recovery status）,15 aspects and 38 indicators,and the normalized weight coefficients of the 3 dimensions were 0.405,0.114 and 0.481,respectively.A total of 106 convalescent children with hematologic malignancies who visited the vaccine evaluation clinic were randomly selected for clinical verification,the overall reliability（Cronbach's α=0.840） and validity（CVI=0.829,KMO=0.839） of the vaccination feasibility evaluation system were high. Among them,76 children were recommended for vaccination after evaluation by clinical medical personnel,and 78 children were recommended for vaccination after evaluation by the vaccine feasibility evaluation system. The consistency test between the two was strong（Kappa=0.858,P<0.01）. Conclusion The feasibility evaluation system of vaccination in convalescent children with hematologic malignancies by modified Delphi Method is relatively complete,and preliminary clinical evidence was good,which can provide new ideas and reference for the vaccination evaluation in convalescent children with hematologic malignancies.

Objective To investigate the level of mastery of occupational health related knowledge among the occupational population in printing industry,improve the working environment for employees,and provide a basis for targeted interventions on employees' risk factors. Methods Totally 179 employees from 10 printing companies in Beijing were selected to conduct an occupational health knowledge questionnaire survey,and the data were collected and analyzed. Results The average score of occupational health related knowledge among 179 workers was（15.0±3.0）points,and 81.0%（145 people） of the surveyed subjects reached the qualified level of occupational health related knowledge. There were statistically significant differences in the scores of occupational health related knowledge among personnel with different educational level,weekly working hours,and whether they had participated in occupational health training（all P<0.05）. The gender,educational level,weekly working hours,and occupational health training all had an impact on awareness（all P<0.05）,while age and work intensity had no impact on awareness（all P>0.05）. The main ways for research subjects with different cultural levels and age groups to obtain occupational health related knowledge included communication with colleagues,books,newspapers,television and audiovisual materials,professional lectures,and bulletin boards. Among them,employees with middle and high school/vocational school education levels mainly obtained knowledge through books and newspapers,employees with college/undergraduate education levels mainly obtained knowledge through bulletin boards,employees aged 18-<35 year-old mainly obtained knowledge through books and newspapers,employees aged 35-<45 year-old mainly obtained knowledge through bulletin boards,and employees aged >45 year-old mainly obtained knowledge through television and audiovisual materials. Conclusions The gender,educational level,working hours,relevant training may be influencing factors on workers' awareness of occupational health knowledge. Different educational levels and age groups of workers have different ways of acquiring occupational health related knowledge. The targeted health interventions should be carried out for workers with different characteristics,and occupational health knowledge should be publicized and popularized in multiple ways to protect the physical and mental health of workers.

Objective To understand the current status and influencing factors of infectious disease prevention and control,disinfection and infection control skills among staff in elderly care institutions in the urban area of Shanghai,in order to provide a basis for the development of relevant policies. Methods From March to April 2023,a questionnaire survey was conducted to gather general information and relevant data on infectious disease prevention and control,as well as the need and attitudes to disinfection and infection control skills,among 536 staff members from 40 elderly care institutions in Huangpu District of Shanghai,and the data were analyzed. Results The proficiency rate of infectious disease prevention skills among staff in elderly care institutions was 55.2%,while the proficiency rate of disinfection and isolation skills was 68.3%,and the proficiency rate of personal protective skills was 23.5%. There were statistically significant differences in the mastery of infectious disease prevention skills among workers based on various factors,including gender,job types,certification status,and work attitudes（all P<0.05）. There were statistically significant differences in the mastery of disinfection and isolation skills among workers based on various factors such as age,job types,duration of work in the current position,monthly income,job satisfaction,certified personnel,and work attitudes（all P<0.05）. There were statistically significant differences in the mastery of personal protective skills among workers in various types of elderly care institution,educational levels,job types,and certified personnel（all P<0.05）. The high monthly income,high satisfaction,positive attitudes were independent protective factors that influence staff members' proficiency in mastering disinfection and infection control isolation skills.The nature of the institution（publicly funded and operated） and certified personnel were independent protective factors that influence staff members' proficiency in personal protective skills. Conclusions The staff in elderly care institutions in urban area of Shanghai have relatively low infectious disease prevention and control,disinfection,and infection control skills,which directly impacts the implementation of hygiene and disinfection work in these institutions. Therefore,early development of operational and replicable hygiene standards for elderly care institutions,joint guidance and supervision by multiple departments,can effectively prevent and control the spread of infectious diseases in elderly care institutions.

Objective To solve the problem of indoor air pollution in health clubs,explore the optimization methods of indoor air quality and centralized air conditioning ventilation system in health clubs. Methods From August to December 2023,28 health clubs in Shanghai were investigated. The current status of indoor air environment in health clubs was studied through the actual on-site survey and the review of design drawings,and analyzed from the aspects of design,operation and maintenance,and management. The computational fluid dynamics（CFD） software was used to simulate various air supply and return methods. Results The indoor pollutants in the 28 health clubs surveyed can be divided into three types：chemical,physical,and biological pollution. 23（82.1%） were remodeled buildings,of which eight had unqualified indoor environmental items. 6（21.4%） had outdoor fresh air outlets that were blocked. 1（3.6%） had an outdoor fresh air outlet that was too low in height. 18（64.3%） lacked cleanliness and maintenance of indoor air outlets. Some clubs had hygiene problems such as high concentration of pollutants indoors and non-standard design of centralized air conditioning and ventilation systems. The numerical simulation results showed that the displacement ventilation method was much more effective than the top-feeding and bottom-returning and top-feeding and top-returning exhaust methods. Conclusion Active implementation of hygienic evaluation,setting reasonable indoor and outdoor fresh air outlets,adopting replacement ventilation exhaust methods and strengthening hygienic management of air-conditioning ventilation systems can significantly reduce indoor pollutant concentrations and maintain a high-quality indoor environment.

The thyroid hormone are a kind of important endocrine hormones that plays a crucial role in human growth,development,metabolism,and other aspects. The abnormal levels of thyroid hormones are closely related to the occurrence and development of various diseases,therefore,accurate and reliable detection of them is of great significance. At present,the detection of thyroid hormones in clinical practice is mainly determined through immunological methods,and the thyroid hormone content in the blood is directly measured through immunological detection techniques.The traditional immunological detection methods for thyroid hormones mainly include radioimmunoassay（RIA） and enzyme-linked immunosorbent assay（ELISA）. These two methods are the most widely used in clinical practice,with high sensitivity and specificity,and can accurately detect the level of thyroid hormones. However,due to the use of radioactive materials and some limitations in the operation process,traditional detection methods also have some limitations. With the continuous development of biotechnology and immunology,some new thyroid hormone detection methods have gradually been introduced. The application of new technologies such as immunofluorescence,chemiluminescence,and immunochromatography not only improves the sensitivity and accuracy of detection,but also reduces the requirements for experimental operators and reduces environmental pollution. These new methods have broad prospects for clinical application and are expected to become the mainstream methods for thyroid hormone detection in the future. Therefore,this article will review the current immunological detection methods as a reference for thyroid hormone detection.
