Objective To understand the current situation of anxiety disorders among general practitioners in Suzhou,analyze the main factors affecting anxiety disorders among general practitioners in Suzhou,and provide a basis and reference for the construction of the general practitioner talent team and the formulation of grassroots health management policies in Suzhou. Methods In May 2022,through literature review,expert consultation,and interviews with general practitioners,research items on the influencing factors of anxiety disorders among general practitioners were collected. Combined with the generalized anxiety disorder（GAD） scale（GAD-7）,a survey questionnaire was developed. A multi-stage sampling method was used to select 1 302 general practitioners in Suzhou as the survey subjects,and a questionnaire survey on their anxiety disorders and influencing factors were conducted through Wenjuanxing and WeChat,and the data were analyzed. Results Among 1 302 general practitioners,149（11.44%）,184（14.13%）,and 439（33.72%） people had severe,moderate,and mild anxiety disorders. The level of anxiety disorder varied among general practitioners based on their age,professional title,level of professional identity,number of children to be raised,number of elderly care to be supported,housing situation,nature of their unit,and overtime frequency. There was a significant positive impact on the degree of anxiety disorder among general practitioners,including age,number of elderly care providers,nature of the organization,and frequency of overtime（P<0.05）. Professional titles had a significant negative impact on the degree of anxiety disorder among general practitioners（P<0.01）. There were six main influencing factors of anxiety disorder in general practitioners：challenging work pressure,obstructive work pressure,career development pressure,epidemic prevention and control pressure,family life pressure,and social environment pressure,with weights of 12.60%,22.48%,14.30%,14.73%,21.67%,and 14.22%,respectively. Conclusions Anxiety disorders are common among general practitioners in Suzhou City. It is recommended to accelerate the construction of the general practitioner talent team,attract more medical talents to join the general practitioner team,improve the assessment and incentive mechanism for general practitioners,reasonably optimize their working hours and intensity,pay attention to the mental health of general practitioners,and increase social support.

Objective To investigate the status quo of transformational leadership,organizational commitment and job burnout of secondary vocational teachers,analyze the intermediary role of organizational commitment between transformational leadership and job burnout,so as to provide a basis for alleviating their job burnout. Methods In July 2022,400 secondary vocational teachers from a provincial four-star vocational middle school in Nantong City were collected by the convenient sampling method. The transformational leadership scale,organizational commitment scale,and job burnout scale were adopted for the questionnaire investigation. SPSS 23.0 was used for data analysis,and AMOS 23.0 was used for intermediary effect test. Results The scores of transformational leadership,organizational commitment and job burnout in secondary vocational teachers were （55.52±25.18）,（33.78±11.34） and （77.37±12.71）points,respectively. The correlation analysis showed that the transformational leadership was positively correlated with organizational commitment（r=0.633,P<0.01）,and the job burnout was negatively correlated with transformational leadership（r=-0.258,P<0.01） and organizational commitment（r=-0.463,P<0.01）. The results of structural equation model showed that organizational commitment played a complete intermediary role between the two,and the intermediary effect was -0.133. Conclusion The level of job burnout of secondary vocational teachers is relatively high,and organizational commitment plays a completely intermediary role between transformational leadership and job burnout of secondary vocational teachers.

Objective To investigate the current situation of job satisfaction of grass-roots general practitioners in Xinjiang and analyze the influencing factors,so as to provide scientific basis for the formulation and implementation of job satisfaction promotion strategies for grass-roots general practitioners in Xinjiang. Methods From May to June 2022,the grassroots general practitioners in Xinjiang were sampled and investigated by the Questionnaire on Job Satisfaction of General Practitioners in Xinjiang Grass-roots Medical Institutions,and the data were analyzed. Results A total of 675 general practitioners were included in the study. The overall job satisfaction score of grass-roots general practitioners in Xinjiang was （4.21±0.86）points. The difference between internal and external satisfaction scores was statistically significant（P<0.05）,and the scores of promotion and training opportunities were the lowest. The unit type,doctor-patient relationship and training times（within one year） were important influencing factors of job satisfaction of grass-roots general practitioners in Xinjiang（all P<0.05）. Conclusions The overall job satisfaction of grass-roots general practitioners in Xinjiang is high. In comparison,the level of job satisfaction of general practitioners in township health centers,less training times（within one year） and lower satisfaction with doctor-patient relationship is lower. In view of these factors,it is necessary to give preference to township health centers through policies and measures,reasonably allocate general practitioners' resources,increase the number of training and enrich the training content,and improve the doctor-patient relationship,so as to improve the job satisfaction of general practitioners.

Objective To explore the relationship between role stress and job burnout of prison policemen in Shaanxi Province,examine the moderating effect of psychological capital on them,so as to provide a basis for intervening job burnout of prison policemen. Methods From July to September 2022,a total of 225 policemen from six prisons in northern Shaanxi,Guanzhong and Southern Shaanxi were selected as the research subjects using convenience sampling method. The Role Stressor Questionnaire,Maslach Burnout Questionnaire General Survey and Psychological Capital Questionnaire were used for investigation,and the data were analyzed. Results The detection rate of job burnout of prison policemen was 83.6%（188/225）. The role stress score[M（P₂₅,P₇₅）] was 50.0（45.0,54.5）points,the job burnout score was 65.00（56.0,72.0）points,and the psychological capital score was（93.4±19.7）points. The job burnout was positively correlated with role stress（r_S=0.281,P<0.01）,and negatively correlated with psychological capital（r_S=-0.194,P<0.01）. The Psychological capital was negatively correlated with role stress（r_S=-0.145,P<0.05）. The psychological capital moderated the relationship between role stress and job burnout（β=-0.156,P<0.05）. The role stress had a positive predictive effect on job burnout in the low psychological capital group（simple slope=0.417,P<0.01）,while role stress could not significantly predict job burnout in the high psychological capital group（simple slope=0.104,P>0.05）. Conclusion The role stress of prison policemen in Shaanxi Province has a positive predictive effect on job burnout,the psychological capital can adjust the influence level of role stress on job burnout,suggesting that prison should intervene in job burnout of prison policemen by reducing role stress and improving psychological capital.

Objective To investigate the therapeutic effect of total saponins of honeysuckle on secretory otitis media in rats after noise exposure and the effect on toll-like receptors-4（TLR-4）-NLR family pyrin domain containing 3（NLRP3） signaling pathway. Methods Totally 50 Wistar rats were divided into normal control group,model control group,low-,medium-and high-dose groups of total saponins of honeysuckle. Except for the normal control group,the rats in the other groups were exposed to a sound pressure level（SPL） of 100 dB and 10 KHz octave noise in the organic glass box for two hours for 15 consecutive days to establish the secretory otitis media model,each drug group was given corresponding drug intervention,while the normal control group and model control group were given an equal volume of normal saline,and the treatment cycle was two weeks. After the treatment,the threshold level of audiological evaluation（ABR） of the rats was determined,the microstructure of the rat cochlear basement membrane was detected by silver nitrate staining,the pathological changes of the rat cochlea were detected by electron microscopy,and the real-time fluorescent reverse transcription method（RT-PCR） method and Western blotting were used to detect the mRNA protein levels of TLR4 and NLRP3 in cochlear tissue,and enzyme-linked immunosorbent assay（ELISA） was used to detect matrix metalloproteinase 9（MMP-9）,myeloperoxidase（MPO）,tumor necrosis factor-α（TNF-α） levels. Results In the normal control group,the structure of the inner and outer hair cells of the cochlea was normal. In the model control group,the structure of the inner and outer hair cells of the cochlea was severely damaged（inverted,missing）,arranged in disorder,and collapsed in a large area,ciliated epithelium swelled,cilia disordered arrangement and partially shedded,and middle ear mucosa thickened,with inflammatory cell infiltration. After the intervention treatment with total saponins of honeysuckle,the degree of damage to the inner and outer hair cells of the cochlea of rats in each group was significantly improved. The structure of cochlear hair cells in the normal control group was normal,while the arrangement of inner and outer hair cells in the model control group was disordered,and there were gaps in the combination with the periprocess of spiral ganglion cells. After the intervention of total saponins of honeysuckle,the arrangement of inner and outer hair cells in the cochlea tended to be normal,there was still a gap at the junction with the periprocess of the spiral ganglion cells,but the gap was smaller. The threshold level of ABR,mRNA protein levels of cochlear TLR4[（0.73±0.12）vs（4.29±0.74）,（0.24±0.06）vs（1.06±0.17）/GAPDH] and NLRP3[（0.84±0.14）vs（3.88±0.63）,（0.30±0.05） vs（1.12±0.18）/GAPDH）],and the levels of MPO,TNF-α,and MMP in model control group were higher than those in the normal control group（P<0.05）. The threshold level of ABR,mRNA protein levels of cochlear TLR4[（4.29±0.74）vs（3.18±0.50）,（2.34±0.34）,（1.52±0.24）,（1.06±0.17）vs（0.90±0.15）,（0.59±0.10）,（0.40±0.06）/GAPDH）] and NLRP3[（3.88±0.63）vs（3.02±0.48）,（2.18±0.37）,（1.46±0.23）,（1.12±0.18）vs（0.83±0.13）,（0.54±0.09）,（0.36±0.06）/GAPDH],and the levels of MPO,TNF-α,and MMP in low-,medium-and high-dose groups of total saponins of honeysuckle were lower than those in model control group（P<0.05）. The threshold level of ABR,mRNA protein levels of cochlear TLR4[（3.18±0.50）vs（2.34±0.34）,（1.52±0.24）,（0.90±0.15）vs（0.59±0.10）,（0.40±0.06）/GAPDH],and NLRP3[（3.02±0.48）vs（2.18±0.37）,（1.46±0.23）,（0.83±0.13）vs（0.54±0.09）,（0.36±0.06）/GAPDH], and the levels of MPO,TNF-α,and MMP in medium- and high-dose groups of total saponins of honeysuckle were lower than those in low-dose group（P<0.01）. The threshold level of ABR,mRNA protein levels of cochlear TLR4[（2.34±0.34）vs（1.52±0.24）,（0.59±0.10）vs（0.40±0.06）/GAPDH] and NLRP3[（2.18±0.37）vs（1.46±0.23）,（0.54±0.09）vs（0.36±0.06）/GAPDH] and the levels of MPO,TNF-α,and MMP in high-dose group of total saponins of honeysuckle were lower than those in medium-dose group（P<0.01）,the dose-effect relationship was obvious（P<0.01）. Conclusion The total saponins of honeysuckle have a significant therapeutic effect on secretory otitis media in rats after noise exposure,and the mechanism may be related to the inhibition of activation of inflammatory TLR-4-NLRP3 pathway by total saponins of honeysuckle.

Objective To explore the effect and mechanism of isoliensinine on lipopolysaccharide（LPS）-induced acute lung injury. Methods C57BL6J mice were randomly divided into four groups：control group,model group（LPS group）,isoliensinine group,LPS+isoliensinine group,12 animals in each group. The mice were treated with intratracheal injection of 200 μg LPS to induce acute lung injury model. The H&E staining,lung wet weight/dry weight ratio and inflammation index were used to evaluate the degree of acute pneumonia. ELISA kit was used to detect pro-inflammatory factors,tumor necrosis factor TNF-α（TNF-α）,interleukin-1（IL-1） and interleukin-6（IL-6） levels. The kits were used to detect reactive oxygen species（ROS）,malondialdehyde （MDA）,superoxide dismutase（SOD） and glutathione reductase（Gpx） levels/activity. The Western blot was used to detect changes in related signal molecules. Results H&E staining showed that the inflammatory infiltration of the lung tissues in the LPS group increased,and the wet weight/dry weight ratio（4.09±0.55vs5.73±0.55） and inflammation index（0.36±0.11vs4.25±0.53） of the lungs were higher than those of the control group. The ELISA results showed that the levels of TNF-α[（45.93±8.08）vs （198.71±37.85）pg/mL],IL-1[（111.31±6.54）vs（151.27±18.39）pg/mL] and IL-6[（50.15±11.72）vs（468.07±41.23）pg/mL] in the lung tissues of the LPS group were significantly higher than those of the control group,the content of ROS（1.00±0.23vs4.73±0.39）and MDA（1.00±0.09vs4.53±0.07） in the LPS group was higher than those of the control group,and the activities of SOD2 [（2.07±0.11）vs（0.74±0.22）U/mg] and Gpx[（188.03±16.64）vs（69.59±13.51）μmol/g] were significantly lower than those of the control group. The lung wet weight/dry weight ratio（4.88±0.39）,inflammation index（3.05±0.49）,inflammatory factors,and contents of ROS（2.31±0.32） and MDA（2.97±0.47） in LPS+isoliensinine group were lower than those in LPS group,while the activities of SOD2[（1.65±0.13）U/mg] and Gpx[（143.61±24.21）μmol/g] were significantly higher than those of LPS group. The Western blot results showed that toll like receptor 4（TLR4） and phosphorylated nuclear factor-κB（NF-κB） of lung tissues in LPS group were significantly increased,while the expression of TLR4 and phosphorylated NF-κB of LPS+isoliensinine group was lower than those of LPS group. Conclusion The isoliensinine can reduce acute lung injury induced by lipopolysaccharide by inhibiting TLR4. The isoliensinine may be a new treatment for lung injury.

Methods A cross-sectional study was conducted from October 2022 to November 2022 in the Inner Mongolia Autonomous Region,in which a questionnaire consisting of a general information questionnaire and an innovation behavior scale was administered to 505 IPCPs from 256 secondary and tertiary medical institutions. Results The total score of innovative behavior of the IPCPs was （35.92±6.58）points,with the highest score on the idea generation dimension[（3.79±0.66）points] and the lowest score on the gaining support dimension[（3.43±0.72）points]. The results of the univariate analysis showed that there were statistically significant differences in the scores of each dimension of innovative behavior among the IPCPs with different health status,hospital level,hospital nature,years of work in the hospital infection management,whether they had a training certificate in hospital infection management,the number of times they attended training related to hospital infection management in the last six months,their average monthly income,the publication of papers about hospital infection in the last five years,and whether they presided over or participated in research projects related to hospital infection（all P<0.05）. The results of the multiple linear stepwise regression analysis showed that the factors influencing the innovative behavior of the IPCPs were,in order of importance,whether they had a training certificate in hospital infection management,the nature of the hospital,the level of the hospital,their health status,and their average monthly income（β=-0.140,-0.127,0.118,0.117,0.094,all P<0.05）. Conclusions The level of innovative behavior of IPCPs in the Inner Mongolia Autonomous Region is at a medium level and there is much room for improvement. It is recommended that training and organizational support on innovative knowledge related to infection control should be strengthened to cultivate the innovative behavior of IPCPs,so as to improve the quality of hospital infection management.

Objective To analyze the status and epidemiological characteristics of syphilis in Rugao City,provide a basis for scientific prevention and control of syphilis. Methods The data of syphilis cases reported in Rugao City from 2012 to 2021 were analyzed,and the annual change percentage（APC） was used to describe the trend of incidence rate. Results From 2012 to 2021,totally 3 902 syphilis cases were reported in Rugao City,the average annual reported incidence was 27.43/100 000,and the incidence was on the rise（APC=15.94%,P<0.01）. The average annual reported incidence of recessive syphilis was 20.49/100 000, the incidence was on the rise（APC=27.75%,P<0.01）,and the peak age group of latent syphilis appeared in ≥60 year-old group. The average annual reported incidence of early syphilis was 6.69/100 000, the incidence showed a downward trend（APC=-4.57%,P<0.01）.The peak age group of male early syphilis was the 20-<30 age group. Before 2016, the peak age group of female early syphilis was the 20-<30 age group. After 2020, the incidence of female early syphilis in the <20 age group and ≥ 60 age group showed an upward trend. The annual average reported incidence rate of late syphilis was 0.26/100 000, The reported incidence rate had no obvious upward trend（APC=3.00%,P>0.05）. For the occupational distribution,the most cases were farmers（61.12%）,followed by household and unemployed（22.40%） and retired individuals（7.66%）. The cases were mainly reported in the main city and adjacent main urban areas,including Rucheng Street,Chengbei Street and Dongchen Town. There was no obvious change trend in the reported incidence of each region from 2012 to 2015,and reported incidence in Rucheng Street showed an upward trend（APC=-6.86%,P<0.05）,while the reported incidence of syphilis in Jiang'an Town was on the rise（APC=10.22%,P<0.05）. Conclusions The incidence of syphilis in Rugao City is on the rise,which is dominated by the recessive syphilis,the early syphilis should focus on women aged <20 years old,men aged 20-<30 years old,women aged 40-<50 years old,and people aged ≥60 years old. It is necessary to carry out targeted publicity and intervention measures for sexually transmitted disease prevention and control,and strengthen publicity and intervention for syphilis prevention and control in rural areas.

Objective To investigate smoking dissuasion behaviors of family members and influencing factors after legislation of smoking ban in public places in Chongqing. Methods From June to August 2021,a questionnaire survey was conducted among families selected from 10 communities in Chongqing by the random sampling. χ² test was used to compare smoking dissuasion efforts among different families and a binary logistics regression was performed for multivariate analysis. Results Among 2 121 participants in the survey,416（19.61%） were smokers,335（80.53%） of whom were advised to quit smoking by their families,600（28.29%） had smoking family members,and 193（32.17%） of whom had tried to dissuade them from smoking. Whether to persuade their families to quit smoking had a correlation with academic background（OR=1.407,95%CI：0.873-2.268）,worry about tobacco affecting children's health（OR=3.065,95%CI：1.331-7.059）,whether the smoker had tried quitting smoking in the last six months（OR=1.684,95%CI：1.087-2.609） or was planning to quit smoking in the future（OR=3.708,95%CI：1.722-7.981）,and whether they would dissuade strangers from smoking around them in the smoking prohibited public places（OR=2.097,95%CI：1.414-3.111）. Conclusions The smoking dissuasion is common in families. The education level,concerns about the impact of tobacco on children's health,as well as the effect of discouraging family members from smoking,have an impact on their discouraging behavior. Families should be encouraged to take advantage of special opportunities such as child birth to persuade family smokers to quit smoking for the sake of the baby's health,and improve the knowledge and tactics in smoking control so as to enhance its effect,to stimulate more dissuasion behaviors and reduce smoking.

Objective To understand the current status and long-term trend of mumps incidence in Jinghzou City from 2005 to 2021. Methods The incidence data of mumps in Jingzhou City from 2005 to 2021 and the birth population data of 0-9 years old from 2004 to 2020 were collected. The descriptive epidemiological methods,Joinpoint regression models,birth cohort analysis,and age-period-cohort（APC） analysis were used to analyze the period of incidence of mumps,the age of high incidence,and the birth year change. The annual percentage change（APC） and average annual percentage change（AAPC） were used to describe the trend of mumps incidence by year. Results A total of 13 298 cases of mumps were reported in Jingzhou City from 2005 to 2021,with an average annual incidence of 13.56/100 000. There was no overall trend change in the incidence of mumps from 2005 to 2021（AAPC=-0.17%,95%CI：-1.21%-0.87%）,and there was a significant downward trend from 2011 to 2021（APC=87.11%,95%CI：13.04 %-98.09%）. The incidence in 5-9 year-old age group was the highest（126.71/100 000）,followed by the10-14 year-old age group（74.47/100 000）. The age distribution was consistent across years. The incidence rate of children aged 0-9 years old born in Jingzhou City from 2004 to 2012 decreased with the increase of birth year（r_s=-0.97,P<0.01）. The results of APC model analysis showed that the age of high incidence of mumps in children aged 0-9 years old in Jingzhou City was 5-6 and 9 years old. The year with the highest incidence of mumps was 2010 to 2011. The incidence risk of the birth cohort from 1998 to 2007 showed a downward trend,the incidence risk of the birth cohort from 2008 to 2012 remained unchanged,and the incidence risk of the birth cohort from 2012 to 2019 decreased slightly. Conclusion Since 2008,the one-dose measles-mumps-rubella（MMR） vaccine has been included in the national expanded immunization program,which has reduced the incidence of mumps in Jingzhou City,but the reduction effect is limited.

Objective To analyze the report incidence and distribution characteristics of the adverse events following immunization （AEFI） in Beihai City from 2017 to 2021. Methods Through the national AEFI information management system and Guangxi immunization planning information management system,the AEFI case information and vaccination data in Beihai City from 2017 to 2021 were collected for descriptive epidemiological analysis. Results From 2017 to 2021,232 AEFI cases of various vaccines were reported in Beihai City,and the timely reporting rate and timely investigation rate were 97.84% and 100.00%,respectively. The total reported incidence of AEFI was 5.49/100 000 doses,of which the reported incidence of general reactions was 3.43/100 000 doses and the reported incidence of abnormal reactions was 1.68/100 000 doses. The difference in the reported incidence of different types of reactions was statistically significant（P<0.05）. Among the reported AEFI cases,there were more males than females,the age was mainly <1 years old,the peak season was April to September,and the region was predominantly Haicheng District. The differences in gender,age,time of occurrence and regional distribution were statistically significant（all P<0.05）. The national immunization program vaccine with the highest reported incidence was the Diphtheria,tetanus and acellular pertussis combinedvaccine（DTaP） with a rate of 17.12/100 000 doses,and the non-national immunization program vaccine with the highest reported incidence was combined diphtheria-tetanus-acellular pertussis-inactivated poliovirus-Haemophilus influenza type b（Hib） conjugate vaccine（DTaP-IPV-Hib）,with a rate of 69.68/100 000 doses. 87.93% of AEFI cases distributed within 1 day of vaccination,and the incidence of reported abnormal reactions was higher for allergic rash,BCG lymphadenitis and angioedema. Conclusions The overall monitoring quality of AEFI in Beihai City from 2017 to 2021 meets the national monitoring requirements,but the monitoring sensitivity needs to be strengthened. The AEFI cases are mainly general reactions,and the reported incidence is within the expected range. It is recommended that the active monitoring should be strengthened in the future to further improve the quality of AEFI monitoring.

Objective To systematically evaluate the relationship between social frailty and adverse health outcomes of the elderly in the community. Methods PubMed,Web of Science,Embase,Cochrance Library,CNKI,WanFang data,and VIP were searched for cohort studies investigating the social frailty and adverse health outcomes of the elderly at home and abroad from inception to August 2022. A meta-analysis on extracted data was conducted by RevMan 5.3 software,and the descriptive analysis was performed on the data that cannot be merged. Results A total of 15 articles were included. The meta-analysis results showed that high-social frail elderly had higher risk of death（HR=1.35,95%CI：1.19-1.53,P<0.01）,disability（OR=1.33,95%CI：1.18-1.50）,P<0.01） and depression（OR=1.68,95%CI：1.25-2.25,P<0.05） than low-social frail group,and each additional social vulnerability deficit was associated with a 4% increased risk of death（HR=1.04,95%CI：1.03-1.05,P<0.01）. The descriptive analysis results showed that social frailty could increase the risks of death,disability,depression,and cognitive decline in the elderly. Conclusions The social frailty of older adults in the community is closely related to death,disability,depression and other adverse outcomes,so the domestic scholars should pay more attention to the social frailty among older adults. It is necessary to identify the social frailty early and formulate corresponding intervention measures to prevent or slow down the progress of social frailty and reduce the occurrence of adverse health outcomes.

The nursing team is an important part of health system in China. However,the number of nursing talents in China's nursing industry is relatively insufficient and unevenly distributed. How to reduce the turnover rate of nurses and attract nursing talents has become a key topic for nursing managers. The self-regulation fatigue can lead to the decrease of nurses' management behavior and the increase of turnover rate,and then affect the quality of nursing,which is not conducive to patient safety and nursing team building. At present,the research on self-regulation fatigue in China is mostly focused on patients with chronic diseases,and there are relatively few studies on nurses. The paper reviews the concept,theoretical framework,evaluation tools,current situation,influencing factors and consequences,and coping strategies of nurses ' self-regulation fatigue,in order to provide reference for nursing managers to formulate intervention programs to reduce nurses' self-regulation fatigue,and ultimately reduce the turnover rate of nurses and promote the development of nursing.

As a first-line place for rescuing critically ill patients,emergency nurses are frequently exposed to various traumatic stress events,and are in a fast-paced and high pressure working environment.
