Abstract:
Objective To investigate the voice handicap index of teachers and its correlation with their work and lifestyle habits, and provide a basis for guiding the prevention and treatment of their voice disorders. Methods In 2020, a total of 494 teachers in 9 educational institutions in Shenzhen City were surveyed with a structured questionnaire to collect information on their work and personal lives and the Voice Handicap Index-10 (VHI) Scale to assess the voice disorder situation. A multifactorial unconditional logistic regression model was used to analyze the influencing factors of voice disorders. Results With a response rate of 91.30%, 451 complete and valid surveys were returned. The median voice handicap index of the surveyed teachers was 9, with a quartile range of (4, 13), and 167 teachers had voice disorders, accounting for 37.03%. Multivariate regression analysis showed that poor sleep quality, the occurrence of emotional distress within the past month, and a large class size were risk factors for voice disorders. For each decrease in sleep quality level (very good, good, poor), each increase in emotional distress severity level (none, mild, moderate, severe), and each increase in the scale of class size (≤ 30, 31-40, 41-50, and ≥ 51 students), the risk of voice disorders among teachers increased by 1.78, 1.90, and 1.58 times, respectively (P < 0.05). Conclusions Some teachers in educational institutions in Shenzhen had voice disorders. To improve their vocal health, it is recommended to organize teaching tasks reasonably, pay attention to mental health conditions and sleep quality, and promote healthy vocal practice.

Abstract:
Objective To understand the occurrence of menstrual abnormalities and possible influencing factors among female employees in the telecommunications service industry. Methods From July to September 2020, a cluster sampling method was used to investigate the menstrual abnormality status of female employees in the telecommunications service industry in Hebei Province in the past 6 months through a self-administered questionnaire. The Female Employee Mental Health Survey Questionnaire was used to investigate occupational stress. A multi-factor logistic regression model was used to analyze the possible influencing factors for menstrual abnormalities. Results A total of 1 202 valid questionnaires were collected, with an effective recovery rate of 94.5%. The average age of the surveyed females was (36.81 ±5.44) years old. 236 females (19.6%) had menstrual abnormalities manifested as menstrual cycle disorders, excessive or insufficient menstrual flow, prolonged or shortened menstrual periods, blood stasis, dysmenorrhea, etc. According to the results of logistic regression, the risk of menstrual abnormalities for female workers with a history of abortion was 2.218 times higher than the risk for female workers without a history of abortion; the risk of menstrual abnormalities for female workers exposed to noise was 2.112 times higher than the risk for female workers who were not exposed to noise; the risk of menstrual abnormalities for female workers with a workweek longer than 40 hours was 3.279-4.340 times higher; and the risk of menstruation abnormalities increased to 1.076 times the initial risk for every 1 point rise in the occupational stress questionnaire score (all P < 0.05). Conclusions A history of artificial abortion, exposure to noise, excessive weekly working hours, and higher occupational stress were risk factors for menstrual abnormalities among female employees in the telecommunications service industry. It is recommended for enterprises to improve the working environment, arrange work shifts reasonably, strengthen mental health education, and promote reproductive health among female employees.

Abstract:
Objective To understand the urinary fluoride level and changes in bone biochemical metabolism indexes among workers exposed to ammonium bifluoride and to explore bone metabolism biomarkers in ammonium bifluoride-exposed workers. Methods Totally 74 workers occupationally exposed to ammonium bifluoride in a semiconductor and liquid crystal panel production enterprise (as an exposed group), as well as 70 workers in a nearby electronic factory (as a control group), were studied. The urinary fluoride, serum osteocalcin, serum alkaline phosphatase, and urine hydroxyproline were measured, and the differences between these two groups were compared. Results The airborne concentrations of hydrogen ammonium bifluoride (calculated as hydrogen fluoride) in the workplaces of the studied plant varied from non-detectable (lower than 0.014) to 0.021 mg/m3, which were lower than the national occupational exposure limit. Seven workers in the exposure group had excessive fluoride values in their pre-shift urine samples, with an excessive rate of 9.45%. There was a positive correlation between the urinary fluoride values of workers in the exposure group and the airborne concentration of hydrogen fluoride (r=0.332, P < 0.05). The urinary fluoride mass concentration of workers in the exposure group [(0.69 ±0.77) mg/L] was higher than that of the control group [(0.47 ±0.17) mg/L], and the difference was statistically significant (P < 0.05). The serum osteocalcin concentration of workers in the exposure group [(15.07 ±3.68) ng/mL] was lower than that of the control group [(16.51 ±4.51) ng/mL], and the difference was statistically significant (P < 0.05). There was no significant difference between the serum alkaline phosphatase concentration [(76.99 ±14.99) U/L] of workers in the exposure group and that of the control group [(75.03 ±22.35) U/L] (P > 0.05). The urine hydroxyproline concentration of workers in the exposure group [(1 134.01 ±145.34) μmol/L] was higher than that of the control group [(721.30 ±138.31) μmol/L], and the difference was statistically significant (P < 0.01). If the workers were grouped according to their urinary fluoride level, those with higher urinary fluoride values than 1.0 mg/L had higher urinary hydroxyproline values than those of those with lower urinary fluoride values (> 0.5 - 1.0 mg/L and > 0 - 0.5 mg/L) (P < 0.05). Conclusions Urinary fluoride and urine hydroxyproline may be sensitive biomarkers of bone metabolism in workers exposed to ammonium bifluoride.

Abstract:
Objective To investigate the adverse effects of low-concentration isocyanate exposure on airway inflammation and lung function and to explore the application of fractional exhaled nitric oxide (FeNO) in occupational health examinations of isocyanate-exposed workers. Methods From 2016 to 2017, a total of 192 workers exposed to isocyanates were selected as the exposure group, and 91 with similar age and gender composition (office and/or logistics personnel) without any exposure to occupational hazards (as references) were studied. Monitoring data of airborne isocyanate concentration in workplaces in the past 5 years were collected. The basic information of all workers was collected, and their lung function, FeNO, and salbutamol bronchial dilation tests were performed. The differences in various indicators among these two groups of workers were compared. Results The airborne isocyanate concentration in workplaces over the past 5 years was significantly lower than the national occupational exposure limit. The forced vital capacity (FVC) and forced expiratory volume in first second (FEV1) of the exposed workers were higher than those of the reference group, while FEV1/FVC was lower than that of the reference group, and the differences were statistically significant (P < 0.001). There was no significant difference in FeNO levels between the exposed workers and the reference workers (P > 0.05). The FEV1/FVC ratio was higher in the exposed workers with exposure time < 7 years than workers with exposure time≥ 7 years (P < 0.05), while there was no significant difference in FeNO levels between these two groups (P > 0.05). There was no significant difference in various indicators of lung function among different workers grouped according to the FeNO levels (P > 0.05). Among 192 exposed workers, 13 had FeNO levels higher than 50 ppb (1 ppb=1×10-9), and among 9 workers receiving bronchial dilation tests 3 workers were positive. Conclusions FEV1/FVC could better reflect the adverse effect of isocyanate, a type of asthmagens, on lung function. FeNO levels cannot indicate the occupational low-level isocyanate exposure, while positive changes shown by bronchial dilation tests in exposed populations occur earlier than changes in lung function. The combination of FeNO measurement and bronchial dilation tests could have certain predictive value for diagnosing and screening occupational asthma.

Abstract:
Objective To analyze the global and Chinese disease burden of hearing loss and its changing trends from 1990 to 2019, and to provide data support for the formulation of hearing loss prevention and control measures. Methods The prevalence, disability-adjusted life years (DALYs), and other disease burden indicators of hearing loss in the whole world and China, as well as related information such as age and gender, were extracted from the Global Burden of Disease database in 2019(GBD 2019). The basic situation of hearing loss disease burden, the distribution of various indicators in age and gender, and the time trend of changes were analyzed. Results From 1990 to 2019, the number of people with hearing loss worldwide increased from 752 million to 1.457 billion, with an increase of 93.75%; during the same period, the number of people with hearing loss in China increased from 199 million to 407 million, with an increase of 104.52%. The increase in hearing loss cases in China was higher than the global level. The number of DALYs for hearing loss worldwide increased from 22.01 million person-years to 40.24 million person-years, with an increase of 82.83%, while the number of DALYs for hearing loss in China increased from 5.58 million person-years to 10.48 million person-years, with an increase of 87.84%. From 1990 to 2019, the age-standardized prevalence rate (ASPR) of hearing loss in the world and China showed an upward trend, with China's rising faster than the world; the age-standardized DALY rate (ASDR) showed a downward trend, with China's falling faster than the world; with age increasing, the number of cases and DALYs for hearing loss showed a trend of an initial increase followed by a decrease; in 1990 and 2019, the ASPR of hearing loss for males in the world or China was higher than that for females (P < 0.001). The proportion of mild hearing loss cases accounted for more than 70% of all hearing loss cases, but DALYs caused by moderate or above hearing loss accounted for more than 60%. Conclusions The disease burden caused by hearing loss in the world and China is still heavy and has a further increasing trend. Government departments are required to take appropriate measures to prevent hearing loss in order to control the growth of the disease burden.

Abstract:
Objective To explore the efficacy of Xuebijing injection in the treatment of emergency patients with severe sepsis and its impact on coagulation function. Methods Seventy-eight patients with severe sepsis were randomly divided into the control group (n=39) and the Xuebijing group (n=39) by the random number table method. All patients in both groups were treated with routine anti-sepsis bundle therapy according to the 2016 International Guidelines for the Treatment of Sepsis and Septic Shock. In addition to these routine treatments, the Xuebijing group was treated with a Xuebijing injection, while the control group was given an equal amount of sodium chloride. The platelet count (PLT), coagulation function, thromboelastography (TEG) values, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, the stay time at the emergency intensive care unit, and the fatality rate within 28 days were compared between these two groups before and after 7 days of treatment. Results After 7 days of treatment, the PLT count in the Xuebijing group increased significantly, and the fibrin/fibrinogen degradation products (FDP) decreased significantly (P < 0.05); the PLT count in the control group continued to decrease (P < 0.01). After 7 days of treatment, FDP and D-Dimer (DD) in the Xuebijing group were lower than those in the control group (P < 0.01), and clot formation time was significantly shortened; α angle, maximum clot strength (MA), and coagulation index (CI) were significantly increased, and all were better than those in the control group (P < 0.05). There was no statistically significant difference in these indicators before and after treatment in the control group (P > 0.05). After 7 days of treatment, APACH Ⅱ scores in both groups decreased compared to before treatment (P < 0.05), but the performance of the Xuebijing group was better (P < 0.05). The 28-day fatality rate in the Xuebijing group was 17.95%, lower than that in the control group at 23.08%. Conclusions Combined with routine symptomatic treatment, Xuebijing injection could effectively improve the coagulation function of sepsis patients, showing a positive role in the treatment of sepsis patients.

Abstract:
Objective The noise hazards and protective measures taken by a large shipbuilding enterprise in Shanghai were evaluated in order to provide a reference for the prevention and control of noise hazards in large enterprises. Methods In March 2016, the noise exposure level of workers was measured according to noise measurement standards, and the classification of the noise hazard level of these workers was done according to the noise standard grading method. Results Totally, the noise level in 149 noise-generating positions in this shipbuilding enterprise was measured, while the individual noise exposure level of 17 sand cleaning workers was measured using personal noise dosimeters. Among 149 positions, the noise level in 122 positions was qualified, with an overall compliance of 73.5%. The equivalent sound level (LEX, 8 h) of noise at 26 polishing positions was higher than the national standard, ranging from 89.1 to 96.0 dB(A). Of 26 polishing positions, one was classified as having a mild noise hazard, 18 as a moderate noise hazard, and 7 as a severe noise hazard. Among 9 air compressor inspection positions, the noise level in 1 position was greater than 85 dB(A) with an equivalent sound level (LEX, 8 h) of 92.7 dB(A), and was classified as a moderate noise hazard. The noise level in positions such as steel pretreatment, welding, assembly, and machine room inspection was all less than 85 dB(A). The individual noise exposure level of 17 sand cleaning workers was higher than the standard, ranging from 94.3 to 96.4 dB(A). Among them, the positions of 3 workers were classified as having moderate noise hazards, and 14 were classified as severe. After wearing earplugs, the converted maximum noise exposure level of polishing workers was 85.0 dB(A), while that of air compressor inspection workers was lower than 85 dB(A), and that of steel pre-treatment workers, welders, assemblers, and inspection workers was lower than 80 dB(A). After wearing earplugs, the converted maximum noise exposure values of 2 sand cleaning workers were 85.2 dB(A) and 85.4 dB(A), respectively, and still higher than 85.0 dB(A), while those of 15 other workers were lower than the national standard. Of 2 123 noise-exposed workers, occupational health examinations showed that 12 workers (3 polishing workers and 9 sand cleaning workers) had occupational contraindications to noise, accounting for 0.06%. Conclusions Noise was the main occupational hazard in large shipbuilding enterprises. It is necessary to improve the process according to the situation of excessive noise, adopt low-noise equipment selection or targeted individual protection measures, and strengthen occupational health examinations to reduce the impact of noise on the health of operators.

Abstract:
Objective To explore the effect of mindfulness intervention on the psychological resilience and professional identity of nursing undergraduates during the epidemic and its mechanisms, and to provide strong evidence for improving the mental health status and professional identity of nursing undergraduates. Methods One hundred and eight nursing students were randomly selected from a pre-survey conducted at a university in Beijing from April 25-30, 2021, of whom 52 were placed in the intervention group for a combined online and offline mindfulness intervention, whereas 56 were placed in the control group and received no intervention. The Resilience Style Questionnaire (RSQ) and Professional Identity for Nurse Students Questionnaire (PINSQ) were used to assess the levels of psychological resilience and professional identity of members in both groups before intervention, 1 week after intervention, and 3 months after intervention (follow-up). SAS 9.4 software was used to evaluate the intervention effect using generalized estimating equations, and the Process test was used to analyze the mediating effect of psychological resilience. Results After intervention, the psychological resilience of the intervention group was higher than that of the control group (P < 0.05); at follow-up, there was no statistically significant difference in psychological resilience between the intervention group and the control group (P > 0.05). The psychological resilience of students in the intervention group increased after intervention and at follow-up compared to before intervention (P < 0.05), but decreased at follow-up compared to after intervention (P < 0.05); there was no change in the level of psychological resilience of control students at each time point (P > 0.05). After intervention, the professional identity score of the intervention group was higher than that of the control group (P < 0.05), and at follow-up time, the professional identity of the intervention group was higher than that of the control group (P < 0.01). The increase in professional identity at each time point in the intervention group was statistically significant (P < 0.05), while there was no statistically significant difference in professional identity in the control group at each time points (P > 0.05). Mindfulness intervention affected professional identity by affecting psychological resilience levels, with a mediation effect ratio of 23.67%. Conclusions A mindfulness intervention could effectively improve the psychological resilience and professional identity levels of nursing undergraduates during the epidemic, providing a basis for subsequent psychological interventions and research.

Abstract:
Objective To analyze the mediating effect of psychological resilience on anxiety and insomnia among medical staff in the fever clinic and to provide a theoretical basis for improving their symptoms of insomnia. Methods From January to July 2022, a general data questionnaire, a 7-item Generalized Anxiety Disorder Scale (GAD-7), a simplified version of the 10-item Connor-Davidson Resilience Scale (CD-RISC-10), and an Insomnia Severity Index (ISI) were used to survey medical staff in the fever clinic of a tertiary hospital in Tianjin. Descriptive statistics and correlation analysis were performed using SPSS 22.0 software; structural equation modeling was constructed using AMOS 25.0; and the mediating effect of psychological resilience on anxiety and insomnia was tested using the Bootstrap method. Results A total of 251 questionnaires were returned, of which 245 were valid, with a valid response rate of 97.6%;40.0% (98/245) of medical staff had symptoms of anxiety, and 39.1% (96/245) had symptoms of insomnia. The longer the working time and the higher the professional title, the higher the level of anxiety among medical staff (P < 0.05). Anxiety was positively correlated with insomnia (r=0.276, P < 0.01), anxiety was negatively correlated with psychological resilience (r=- 0.388, P < 0.01), and psychological resilience was negatively correlated with insomnia (r=- 0.290, P < 0.01). Psychological resilience had a mediating effect between anxiety and insomnia, with a mediating effect of 0.074, accounting for 33.3% of the total effect. Conclusions The phenomenon of anxiety and insomnia among medical staff in fever clinics should not be ignored. Department managers should pay attention to the mental health status of these medical staff, take targeted measures to improve their psychological resilience level, improve their sleep quality, and ensure that fever clinic medical staff maintain a good mental state.

Abstract:
Objective To analyze the psychological experience characteristics of nursing staff with different roles in response to sudden public health emergencies so as to formulate targeted intervention strategies against the negative psychology of nursing staff. Methods Based on the principle of information saturation, purposive sampling was used to select nursing staff with different roles, and semi-structured interviews were conducted from July to August 2022. The interview data were sorted and analyzed by QSR Nvivo 11.0 software. Results A total of 18 nursing staff members were included in this interview, including 9 managers and 9 non-managers. Four tree nodes were determined based on the interview materials: positive orientation of work feelings, negative experience in the support process, influencing factors of negative experience, and psychological adjustment measures. The high-frequency words were "problem", "work", "influence", "psychology", "pressure", "communication", etc. The most important sub-node in the tree node of "influencing factors of negative experience", "psychological adjustment measures", "positive orientation of work feelings" and "negative experience in the support process" was "management pressure", "self-release path", "sense of value" and "worry", respectively. The proportion of negative matrix coding words for nursing management personnel was much greater than that for non-management personnel, while the proportion of positive matrix coding words was much smaller than that for non-management personnel. Conclusions There were different degrees of negative psychological tendencies among front-line emergency nurses in sudden public health emergencies, among which management personnel were more prominent. Corresponding psychological adjustment intervention strategies should be formulated for nursing managers in emergency work.

Abstract:
Objective The influencing factors of emergency response to acute occupational poisoning accidents were analyzed in order to provide a basis for relevant departments to strengthen their emergency response capabilities against these accidents. Methods Based on the 4 R theory of crisis management, the influencing factors of emergency response to acute occupational poisoning accidents were extracted from four aspects: emergency preparedness, emergency plan, response, and recovery. The multi-level hierarchical structure of the influencing factors was determined using interpretative structural modeling (ISM), and then the driving force and dependence of each influencing factor were calculated using the cross-impact matrix multiplication applied to classification (MICMAC), and targeted emergency response strategies were proposed. Results A total of 12 influencing factors for emergency response to acute occupational poisoning accidents were identified. Among them, emergency plans, emergency drills, emergency training, and organizational scheduling were not only the most fundamental, deep-seated factors affecting emergency response to acute occupational poisoning accidents but also the factors with the strongest driving force. Controlling poisons and isolating hazardous areas were the most critical direct factors in the emergency response to acute occupational poisoning accidents. Conclusions In the emergency response to an accident, priority should be given to controlling poisons and isolating hazardous areas. Simultaneously, efforts should be made to strengthen the construction of emergency plans, emergency drills, emergency training, and organizational scheduling.

Abstract:
Objective To construct an evaluation index system for public health emergency preparedness in tertiary general hospitals in China. Methods Based on a literature review, theoretical analysis, expert panel meetings, and the Delphi method, the analytic hierarchy process was used to construct the evaluation index system for emergency preparedness capacity. Results The response rates of the two rounds of questionnaires were 100%, the authority degree of experts was 0.879, and the Kendall coordination coefficients were 0.172 and 0.621 (P < 0.001), respectively. Finally, seven first-level indicators, 20 second-level indicators, and 74 third-level indicators were formed. The first-level indicators and their weights were: command and management (weight 0.209), emergency information communication (weight 0.123), emergency safety (weight 0.092), pre-check and triage (weight 0.209), emergency response (weight 0.034), emergency human resources (weight 0.123), and emergency equipment and materials (weight 0.209). Conclusions The evaluation index system for public health emergency preparedness capacity in tertiary general hospitals constructed in this study has good scientific and practical applicability. It can provide a basis for investigating, standardizing, and improving the public health emergency preparedness capacity in tertiary general hospitals, and it can also provide a basis for improving the index system of public health emergency capacity in hospitals.

Abstract:
Objective The inter-laboratory comparison results of occupational health testing laboratories in Gansu Province were analyzed to evaluate the testing capabilities and quality of occupational health testing laboratories in the province. Methods Laboratories participating in the inter-laboratory comparison of occupational health technical service organizations in Gansu Province during the period of 2019-2021 were selected for the study, and the test results of the levels of organic substances, metals, and inorganic non-metallic chemicals in the air of the workplaces, metal chemicals in biological materials, and the levels of free silica in dust were statistically analyzed. Results A total of 272 comparison items were conducted from 2019 to 2021, and 242 items were reported and 220 were qualified, for a qualification rate of 90.9%. The qualification rates of organic substances, metals, and inorganic non-metallic chemicals in the air of the workplaces, metal chemicals in biological materials, and the levels of free silica in dust were 91.4%, 88.6%, 97.9%, 92.9%, and 80.8%, respectively. There was no statistically significant difference in the qualification rate between grade A and grade B institutions or between public and private institutions (P > 0.05). The qualification rate and the number of participating institutions increased year by year over this time, with the qualification rate increasing from 82.69% to 93.48% and the number of institutions increasing from 13 to 28. Conclusions The testing level of occupational health technical service organization laboratories in Gansu Province was good; however, the overall quality and level of laboratory testing still need to be improved, and investment in and management of various laboratories should be increased.

Abstract:
Objective To optimize the pretreatment process of the national standard method of solvent desorption-micro acid digestion graphite furnace atomic absorption spectrophotometry for the determination of tetraethyl lead in workplace air. Methods A new tetraethyl lead desorption reagent was used, and the digestion time was adjusted. The detection limit, recovery rate, and relative standard deviation of tetraethyl lead in workplace air after pretreatment optimization were calculated through experiments and compared with national standard methods. Results n-Hexane was selected as the desorption reagent in the pretreatment process, and 10 μL concentrated nitric acid was used for digestion for 60 min. After pretreatment optimization, the detection limit was 0.001 3 μg/mL with an average recovery rate of 98.3% and an average relative standard deviation of 2.7%, which met the relevant requirements of laboratory quality control specifications. Compared with the national standard method, the optimized method used less concentrated nitric acid, had a lower experimental blank, and had a higher recovery rate. Conclusions The improved method was more convenient to operate, had a low reagent blank value, good result repeatability, and a high sample recovery rate.
