目的 了解职业院校教师组织支持、心理资本与工作投入现状及相关性，为职业院校开展师资队伍改革提供借鉴参考。方法 2023年9—12月，采用便利抽样法，运用一般资料调查表、组织支持感量表、心理资本量表和工作投入量表对四川省5所职业院校282名教师开展调查，并对数据进行分析。结果 职业院校教师组织支持感得分为（3.36±0.39）分，心理资本得分为（4.10±0.49）分，工作投入得分为（3.52±0.54）分；三者间均呈正相关（r=0.943、0.884、0.898，均P<0.01）；组织支持和心理资本对教师工作投入具有直接正向作用，且心理资本在组织支持和工作投入间存在部分中介效应（18.05%）。结论 职业院校教师组织支持、心理资本与工作投入均处中等水平，心理资本和组织支持对教师工作投入均具有积极效应。职业院校应进一步强化提高对教师的组织支持和心理资本投入水平，提升其职业价值感和使命感，促进职业教育教学质量不断提升。
Background: Chlamydia trachomatis and Mycoplasma infections have been regarded as severe challenges to public health worldwide because their potential risk of leading to serious reproductive complications. C. trachomatis is the most common sexually transmitted bacterial infections and the prevalence has been increasing in recent years. As a newly discovered pathogen, Mycoplasma genitalium has gradually been recognized as important sexually transmitted infection and even been called a “new chlamydia”. There are no official epidemiological data of M. genitalium in China especially in women with lower reproductive tract infection. This work aims to understand the prevalence and risk factors of M. genitalium and C. trachomatis in women with lower reproductive tract infections and to provide reference for the formulation of health policy in China. Methods: This study was conducted in the gynecological clinics of 12 hospitals geographically located in different regions in China. Women with purulent cervical secretions or abnormal vaginal microecology were included as the research group, and those with normal vaginal microecology and cervical secretions were included as the control group. A total of 2190 participants were recruited in this project including 1357 of research group and 833 of control group. All participants were required to complete questionnaires, whose vaginal discharge were collected for vaginal microecology test and cervical discharge for detection of M. genitalium and C. trachomatis. Results: The prevalence of C. trachomatis and M. genitalium were 7.1% (96/1357) and 3.8% (51/1357), respectively in research group. The prevalence of C. trachomatis and M. genitalium varied in different regions. Infection rates of C. trachomatis and M. genitalium were higher in women with abnormal vaginal microecology (C.t P = 0.038, M.g P = 0.043), especially in women with bacterial vaginosis and mixed vaginitis, of which C. trachomatis showed statistical differences (bacterial vaginosis, P = 0.035; mixed vaginitis, P = 0.0001) and M. genitalium was close to statistical differences (bacterial vaginosis, P = 0.057; mixed vaginitis, P = 0.081). Alcoholism and abnormal vaginal microecology were positively correlated with both C. trachomatis and M. genitalium infection. Increasing age, being married and Zhan Zhang and Xiaonan Zong contributed equally to this paper *Correspondence: liuzhaohui@ccmu.edu.cn 1 The Gynecology Department of Beijing Obstetrics and Gynecology Hospital, Capital Medical University, No. 251 of Yaojiayuan Road, Chaoyang District, Beijing, China Full list of author information is available at the end of the article Page 2 of 11 Zhang et al. BMC Infectious Diseases (2023) 23:2 multi-parity were negatively correlated with C. trachomatis infection. There is a positive correlation between multiple sexual partners, diversed styles of sex and C. trachomatis infection. Conclusions: Women with lower genital dysbiosis have an increased risk of C. trachomatis and M. genitalium. The overall prevalence of M. genitalium is lower than that of C. trachomatis, while they have similarities in the characteristics of infection. Although M. genitalium is not routinely screened as C. trachomatis in young women, attention should be paid to M. genitalium infection in young women with abnormal vaginal microecology or having childbearing
目的 设计核医学场所布局分区和通风方案并进行验证检测,为规范核医学场所的防护、保障核医学人员的辐射安全提供基础条件.方法 以2019-2022年北京市某医院设计并建成投入使用的核医学场所作为调查对象,通过现场勘察,查阅资料和综合分析,对该核医学场所的布局和通风进行设计,并在场所投入运行后进行放射性污染水平和通风效果验证检测,依据有关法规和技术标准进行分析评价.结果 确定了该核医学工作场所的布局分区和通风设计方案,验证检测结果表明,场所内废物桶表面放射性表面污染水平最高,为6.40 Bq/cm3,其次为便池和注射台,分别为0.70和0.50 Bq/cm2,场所内其他设施和物品表面以及现场工作人员体表均未发现明显的放射性污染;通风柜操作口截面风速为1.0 m/s.场所内表面污染水平和通风分别满足GB 18871-2002《电离辐射防护与辐射源安全基本标准》和GBZ 120-2020《核医学放射防护要求》的要求.结论 核医学场所布局分区和通风是防护设计的关键,验证检测是维护场所安全运行的有效手段,应将放射防护理念贯穿到每一个设计环节,从根本上为核医学场所运行的辐射安全提供可靠的保障.
