Objective To investigate the sources of job burnout among nurses in tumor operating room,and propose corresponding strategies to alleviate job burnout. Methods A total of 72 nurses in tumor operating rooms from Harbin Medical University Cancer Hospital were selected by convenience sampling method from January to March 2023 as survey subjects. General information survey questionnaires,Maslach burnout inventory（MBI） and the Chinese nurse work stressors scale were used to investigate,and the coping methods were explored. Results The average scores of emotional exhaustion sense,indifference sense to work and personal non-achievement sense of 72 nurses in tumor operating rooms were （21.95±5.82）,（5.95±1.82） and （37.98±9.16）points,respectively. 56.94%（41/72） of nurses had a high level of job burnout in the dimension of emotional exhaustion,with a score of ≥19 points. 40.28%（29/72） of nurses had a high level of job burnout in the dimension of job indifference,with a score of ≥6 points. 59.72%（43/72） of nurses had a high level of job burnout in the dimension of personal non-accomplishment sense,with a score of ≤39 points. There were statistically significant differences in job burnout among operating room nurses with different age groups,working years in operating room and daily average effective nursing time（all P<0.05）. The main source of work stress for 72 nurses in tumor operating rooms was worrying about errors and accidents at work,and the secondary sources of work stress were low social status from nursing work and low salary and other welfare. The job burnout of nurses in tumor operating rooms was positively correlated with working years,daily average effective nursing time and work stressors（all P<0.05）. Multiple linear regression analysis showed that age,daily average effective nursing time and work stressors（low social status from nursing work,low salary and other benefits,worrying about errors and accidents in work） could be applied to predict job burnout of nurses in tumor operating room. Conclusion The level of job burnout among nurses in tumor operating rooms is relatively high,especially in those with age ≥35 years and heavy workload. It is necessary to pay attention to the main and secondary work stressors,adjust management methods and strengthen psychological construction for nurses in tumor operating room.

Objective To analyze the spatial distribution of job burnout prevalence among personnel in biosafety laboratory（BSL） in Xinjiang region,and explore the influencing factors of job burnout among BSL personnel. Methods In May 2021,a cross-sectional survey was conducted to recruit 7 924 biosafety laboratory staff from 4 prefectures-level cities,5 regions,5 autonomous prefectures-districts and districts in Xinjiang. Maslar burnout scale（MBI-GS） was used to measure job burnout. Using the prefecture-level city,region and autonomous prefecture as the spatial analysis units,Xinjiang administrative region boundary vector map as the basic map,ArcGIS 10.8 and SPSS 26.0 software were used for spatial analysis of job burnout and analysis of the influencing factors of job stress. Results The detection rate of job burnout among BSL personnel in Xinjiang region was 83.3%. The local spatial analysis showed that the job burnout of biosafety laboratory personnel in Xinjiang had clustering characteristics,and there was a "high-high" clustering area among BSL personnel in Xinjiang,mainly distributed in the northern region of Xinjiang. The hotspots of job burnout prevalence were concentrated in Turpan City,while the cold spots of job burnout prevalence were mainly concentrated in Kasha and Holtan areas. The prevalence of job burnout was almost a straight-line distribution in the east-west direction,with an increasing trend from the west to the east. The north-south direction showed an "n" shaped distribution,with an initial increase and then a decrease from the south to the north. Multivariate logistic regression analysis showed that age,education level,job category,monthly income and laboratory grade were all influencing factors for job burnout among BSL personnel（all P<0.05）. Conclusion The prevalence of job burnout among BSL personnel increased from the west to the east,and increased first and then decreased from the south to the north. The prevalence of job burnout among BSL personnel in Xinjiang showed a spatial clustering distribution,with a spatial positive correlation and a certain degree of regional clustering. Age,education level,job category,monthly income and laboratory grade were all the influencing factors of job burnout among BSL personnel.

Objective To explore the effect and mechanism of dihydromyricetin（DHM） in improving nonalcoholic steatohepatitis （NASH） of mice induced by choline deficient L-amino acid restricted high-fat diet（CDAHFD）. Methods The NASH model was established by feeding C57BL/6J mice with CDAHFD for 4 weeks. Twenty-four male mice were randomly divided into three groups（CT,CDAHFD,and DHM）,the CT group was provided with the standard food,and other groups were fed with the CDAHFD diet. Mice in the DHM group were gavaged with 200 mg/kg·bw DHM daily. Mice in CT and CDAHFD groups were gavaged with normal saline. The food intake and body mass of mice were recorded. After 4 weeks of intervention,the biochemical indexes of serum and liver tissue were detected. To observe the histomorphologic changes of the liver,the HE,Oil red O,and Sirius red staining were performed. The relative mRNA expression levels of genes related to liver inflammation,lipid deposition,and fibrosis were determined by qRT-PCR. Results Compared with the CT group,the liver index of mice in the CDAHFD group was significantly increased（P<0.05）,and DHM intervention significantly reversed the serum alanine aminotransferase and aspartate aminotransferase levels induced by CDAHFD,as well as the NAFLD activity score. The content of liver triglyceride and total cholesterol content,the expression of fibrosis related genes in liver tissue（Co1α1,Col3α1,Timp1）,inflammatory and chemokine related genes（Tnf-α,Cxcl2,Cxcl10,Mcp1mRNA）,and the level of tumor necrosis factor-α,Interleukin-1 β protein in liver tissue increased（P<0.05）. Compared with CDAHFD group,DHM also increased the Pparα mRNA expression and glutathione as well as the superoxide dismutase content in liver（P<0.05）. The results of H&E staining,oil red O staining and Sirius red staining also showed that liver lipid deposition and collagen fiber deposition were significantly improved in DHM intervention group. Conclusion DHM can improve the liver injury,hepatic steatosis and fibrosis in CDAHFD induced NASH of mice. As for the mechanism,anti-inflammation and anti-oxidant maybe play a key role in the process.

Objective To analyze the correlation between CD4⁺ T lymphocytes,viral load and drug resistance detection results of AIDS patients after antiviral therapy in Heze City in 2022,and provide basis for judging the efficacy of anti-viral therapy of AIDS patients. Methods A total of 1 172 peripheral blood samples from AIDS patients in Heze City after antiviral therapy were collected for CD4⁺ T lymphocyte count detection. The plasma was separated and tested for viral load（VL） and drug resistance. The data were analyzed. Results After antiviral therapy,787 patients（67.15%） had CD4⁺ T lymphocytes ≥400 cells/μL and the viral inhibition rate（VL<1 000） reached 92.32%. The composition of CD4⁺ T cell count in AIDS patients with different viral content was negatively correlated（r=-0 250,P<0.01）. The proportion of drug-resistant cases in the failure of antiviral therapy was 44.44%,and the drugs with a higher incidence of resistance were nevirapine（NVP）,efavirenz（EFV）,emtricitabine（FTC） and lamivudine（3TC）. Conclusion In 2022,the proportion of antiviral failure and drug resistance in Heze City is relatively low. The combination of peripheral blood CD4⁺ T lymphocyte detection and viral load detection can better guide the effectiveness of antiviral therapy.

Methods From May to June 2023,medical staff in midwifery institutions in Jiangsu Province were selected by convenient sampling method. Based on Chinese version of Zelaya AIDS discrimination scale,the Chinese version of the stigma discrimination scale for medical staff was used for reference to measure the status quo of medical staff's discriminatory attitude towards PLWHA mother infant interruption. Results A total of 16 008 questionnaires were collected,of which 15 490 were valid. The survey showed that medical personnel currently exhibit severe discrimination in worrying about infectious diseases,with a score of（2.70±0.80）points,followed by seeking medical treatment and social discriminatory behavior,with a score of（2.33±0.57）points. They showed a good attitude towards policy and environmental support for medical institutions,with a score of（2.03±0.55）points. Multivariate analysis showed that male,medical staff under 30 years of age,high education level,urban registered residence,people with less than 5 years of service,low occupational exposure,knowledge of prevention and control regulations and action plans,and medical staff who had participated in hospital training had significantly lower discrimination（all P<0.05）. Conclusion There is a certain degree of AIDS discrimination among medical staff in midwifery institutions in Jiangsu Province. Among them,medical workers have negative attitudes and discrimination. The main reason is that they fear and misunderstand the spread and infection of AIDS. Classified and targeted anti-discrimination health education for medical personnel can effectively improve the status of discrimination by letting them know the "Regulations on the Prevention and Control of AIDS","The Norms for the Prevention of Mother to Child Transmission of AIDS,Syphilis and hepatitis B（2020） ","Action Plan for the Elimination of Mother to Child Transmission of AIDS,Syphilis and hepatitis B（2022-2025） ".

Objective To investigate the quality of life of elderly hospitalized cases with falls in Putuo District of Shanghai,and explore its influencing factors,so as to provide scientific basis for improving the quality of life of elderly hospitalized cases with falls. Methods The patients hospitalized for the first time due to falls in the second and third level hospitals in Putuo District of Shanghai from January to December 2022 were derived from the injury hospitalization monitoring system,and 1 182 eligible cases were investigated based on the questionnaire designed by the MOS 36-item short from health survey（SF-36） scale. Results The scores of physical health,mental health and total quality of life of elderly hospitalized cases with falls six months after discharge were （51.53±22.94）,（57.98±21.21） and （54.76±21.39）points,respectively. The passing rates of physical health,mental health and total quality of life scores were 35.20%,44.40% and 41.90%,respectively. Comparing the scores of quality of life in different dimensions of different genders,the scores of males were higher than those of females. Except for social vitality,social function and mental health,the differences in scores between males and females were statistically significant（all P<0.05）. The results of multivariate logistic regression analysis showed that gender,regular follow-up visits,housework,sleep and exercise were the factors affecting the quality of life of elderly hospitalized cases after six months of discharge. Conclusion The quality of life of elderly hospitalized patients with falls in the second and third level hospitals in Putuo District of Shanghai is generally poor after half a year of rehabilitation. In addition to taking intervention measures to improve the quality of life,fall prevention should be strengthened to avoid the occurrence of serious fall injuries.

Objective To analyze the epidemiological and etiological detection characteristics of measles in Heze City from 2004 to 2023,and provide data support for eliminating measles. Methods Statistical and descriptive analysis was conducted on the epidemiological characteristics and etiological detection results of measles cases reported in Heze City from 2004 to 2023. Results From 2004 to 2023,3 745 measles cases were reported in Heze. Taking every five years as a statistical period,the highest number of cases in 2004 to 2008 was 2 213,with an average annual incidence rate of 5.43/100 000,the lowest number in 2019 to 2023 was only 22 cases,with an average annual incidence rate of 0.05/100 000. The incidence of measles was mainly in winter and spring,and the peak period was April to May from 2004 to 2013,the peak period was January to March from 2014 to 2018. From 2019 to 2023,due to the low incidence of cases,there were no obvious seasonal characteristics of measles. The incidence of measles in each county ranged from 0 to 32.31/100 000,and the difference was statistically significant（χ²=731.020,P<0.05）. The incidence ratio of male to female was 1.79 ∶ 1,with the majority of cases being those without a history of immunity or those with unknown immunity,accounting for 52.6%（806/1 532） and 32.4%（496/1 532）,respectively. From 2004 to 2018,the incidence of measles showed a "bidirectional shift" trend in age composition,constituent ratio of incidence in age group 0-<8 months increasing from 11.97%（265/2 213） to 25.74%（165/641）,and constituent ratio of incidence in age group ≥20 years increasing from 13.06%（289/2 213） to 33.85%（217/641）. A total of 576 etiological detection samples were collected in Heze from 2013 to 2023,of which 76 were positive for measles nucleic acid. 47 measles virus strains were isolated from positive measles nucleic acid samples,all of which were H1 genotype. Conclusion The incidence rate of measles in Heze City showed a downward trend from 2004 to 2023,especially after 2017,approaching or achieving measles elimination goals. However,due to the severe global measles incidence situation in recent years,the incidence rate continued to rise,which became a threat to consolidate measles prevention and control. The future work should focus on increasing the monitoring of mobile workers and foreign humans,insisting on carrying out high quality leak detection and vaccination work,improving the sensitivity of the surveillance system,improving the level of population immunity,and preventing the spread of imported wild viruses.

objective To understand the status of quality of life and its possible influencing factors of employees in automobile manufacturing enterprises in Liuzhou,and provide reference for maintaining the physical and mental health of employees. Methods From February to April 2023,a self-designed questionnaire and the medical outcomes study 36-item short from health survey（SF-36）（Chinese version） was used to investigate the quality of life on 1 150 employees in Liuzhou automobile manufacturing enterprises,and the factors affecting the quality of life of employees in automobile manufacturing enterprises in Liuzhou were analyzed. Results The scores of physiological function dimension,physical function dimension and physical pain dimension of employees in Liuzhou automobile manufacturing enterprises were （92.93±13.08）,（88.07±25.59） and （94.14±10.83）points,respectively. The scores of overall health dimension,vitality dimension,social function dimension and emotional function dimension were （76.40±17.52）,（73.64±16.53）,（90.20±14.63） and （88.31±26.34）points,respectively. The mental health dimension score was （73.71±14.83）points,the physical component score（PCS） was （87.88±11.44）points,and the mental component score（MCS） was （81.47±12.92）points. Among them,employees scored the highest in the dimension of physical pain,at （94.14±10.83）points,the vitality dimension scored the lowest,at （73.64±16.53）points. The factors that affected PCS were length of service,employment status,monthly income,education level,and body mass index（BMI）,while the factors that affected MCS were length of service,employment status,alcohol consumption,and monthly income. Conclusion The score of physical health is higher than that of mental health of employees in automobile manufacturing in Liuzhou. Therefore,more attention should be paid to the psychological and emotional well-being of employees,and key factors affecting their quality of life should be regulated.

Objective To investigate the current situation and correlation of job insecurity,emotion regulation strategies and sleep quality of surgical medical staff in grade-A tertiary hospitals,and to explore the influence of job insecurity and emotion regulation strategies on sleep quality. Methods A cross-sectional study design was adopted to select 308 surgical medical staff from 5 grade-A tertiary hospitals in Sichuan Province as the survey subjects in August 2023. The work insecurity scale,emotion regulation strategy scale,and sleep quality scale were used for the survey to analyze the relevant influencing factors of sleep quality among surgical medical staff in grade-A tertiary hospitals. Results The Pittsburgh sleep quality index（PSQI） score of 308 surgical medical staff was （8.34±4.56）points,of which 241（78.25%） surgical medical staff had a total PSQI score of ≥5 points,with different degrees of sleep disorders. The score of job insecurity was （14.84±3.80）points,the score of emotion regulation strategy was （45.31±12.08）points. Univariate analysis showed that there were statistically significant differences in the total score of sleep quality among surgical medical staff with different gender,age,marital status,education level,job category,professional title,night shift rotation,frequency of exercise（times/week）,health status,presence of chronic disease,participation in psychological decompression training,coffee and tea consumption（all P<0.05）. Correlation analysis showed that the total score and each dimension score of PSQI of surgical medical staff were positively correlated with the total score and each dimension score of job insecurity（r=0.317-0.675,all P<0.05）,and negatively correlated with the total score and each dimension score of emotion regulation strategy（r=-0.241- -0.684,all P<0.05）. Multivariate analysis showed that night shift rotation,frequency of exercise,presence of chronic diseases,psychological decompression course training,job insecurity and emotion regulation strategies were the main influencing factors of sleep quality among medical staff in emergency department（all P<0.05）,which explained 66.6% of the total variables. Conclusion The sleep quality of surgical medical staff in grade-A tertiary hospitals in Sichuan Province is poor,and most medical staff have different degrees of sleep disorders. Among them,job insecurity is a risk factor for sleep quality,and emotion regulation strategy is an important protective factor. Hospital managers should pay attention to the sleep health status of medical staff,with a focus on reducing their job insecurity,and improving their emotional regulation strategies to improve their sleep quality.

Objective To explore whether the symptoms of attention deficit hyperactivity disorder（ADHD） affect the sleep quality of college students,and examining whether stress plays a mediating role in it. Methods From February to May 2023,a survey was conducted on 306 college students in Guangzhou,using the adult attention deficit hyperactivity disorder self rating scale,Pittsburgh sleep scale,and college student stress scale. Results The screening rates for attention deficit symptoms,hyperactivity and impulsivity symptoms,as well as comorbidities of ADHD,sleep disorders,and stress disorders among college students in Guangzhou were 25.91%,4.32%,14.95%,60.13%,and 17.61%,respectively. The number of children in the family affected the comorbidities of attention deficit and hyperactivity（t=2.49,P<0.05）. Correlation analysis showed that ADHD symptoms,sleep quality, and stress were significantly positively correlated with each other（r=0.205-0.357,all P<0.01）. Structural equation modeling showed that ADHD symptoms could indirectly predict sleep quality through stress（ADHD symptoms → stress → sleep quality）,and stress played a completely mediating role in the impact of ADHD symptoms on sleep quality（β=0.168,P<0.01）. Factor analysis further indicated that ADHD symptoms had the most significant impact on daytime dysfunction in sleep quality through stress（β=0.140,P<0.01）. Conclusions The symptoms of ADHD in college students can affect their sleep quality through stress. ADHD symptoms in college students can increase their stress levels,then reducing their sleep quality.

With the continuous increase in the number of elderly patients with chronic diseases,the phenomenon of social frailty of elderly patients with chronic diseases is becoming more and more significant. The social frailty is one of the important dimensions of frailty,which can lead to a decrease in the quality of life,prolongation of the disease process,and an increased risk of death in elderly patients with chronic diseases. At present,most of the studies related to social frailty in China focus on the elderly in the community,and there are relatively few studies on elderly patients with chronic diseases. Therefore,this paper reviews the assessment tools,the status quo and related factors of social frailty in elderly patients with chronic diseases,and puts forward relevant suggestions to provide reference for early identification and intervention of social frailty in elderly patients with chronic diseases.
