A comparison of the relationships between psychosocial factors,occupational strain,and work ability among 4 ethnic teacher groups in China

The present study compared the level of occupational strain and work ability among Han, Hui, Uygur, Hui, and Kazakh teachers, and explored ethnic differences based on the associations of psychosocial factors at work, occupational strain, and work ability. A cross-sectional survey was conducted among 2,941 teachers in primary and secondary schools in Xinjiang Province, China. Psychosocial factors, occupational strain, and work ability were measured using the Occupation Stress Inventory—Revised Edition (OSI-R) and Work Ability Index. Han and Hui teachers experienced reduced work ability compared with Uygur and Kazakh teachers, and this finding was caused, in part, by exposure to psychosocial factors at work. The vocational and psychological strains caused by these factors play an important role in reduced work ability among all ethnic teacher groups. The findings indicate the importance of taking action to reduce occupational strain for promoting teachers' work ability in multiethnic workplaces.     

Myeloid-derived suppressor cell (MDSC) key genes analysis in rat anti-CD28-induced immune tolerance kidney transplantation

BackgroundIn the field of transplantation, inducing immune tolerance in recipients is of great importance. Blocking co-stimulatory molecule using anti-CD28 antibody could induce tolerance in a rat kidney transplantation model. Myeloid-derived suppressor cells (MDSCs) reveals strong immune suppressive abilities in kidney transplantation. Here we analyzed key genes of MDSCs leading to transplant tolerance in this model.MethodsMicroarray data of rat gene expression profiles under accession number {"type":"entrez-geo","attrs":{"text":"GSE28545","term_id":"28545"}}GSE28545 in the Gene Expression Omnibus (GEO) database were analyzed. Running the LIMMA package in R language, the differentially expressed genes (DEGs) were found. Enrichment analysis of the DEGs was conducted in the Database for Annotation, Visualization and Integrated Discovery (DAVID) database to explore gene ontology (GO) annotation and their Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Their protein-protein interactions (PPIs) were provided by STRING database and was visualized in Cytoscape. Hub genes were carried out by CytoHubba.ResultsThree hundred and thirty-eight DEGs were exported, including 27 upregulated and 311 downregulated genes. The functions and KEGG pathways of the DEGs were assessed and the PPI network was constructed based on the string interactions of the DEGs. The network was visualized in Cytoscape; the entire PPI network consisted of 192 nodes and 469 edges. Zap70, Cdc42, Stat1, Stat4, Ccl5 and Cxcr3 were among the hub genes.ConclusionsThese key genes, corresponding proteins and their functions may provide valuable background for both basic and clinical research and could be the direction of future studies in immune tolerance, especially those examining immunocyte-induced tolerance.     

Commentary: Broadening the research remit of participatory methods in autism science – a commentary on Happé and Frith (2020)

Autism science has transformed beyond recognition in the last two decades. International investment has grown extensively and the number of papers published on autism has increased 10-fold (Pellicano et al., 2014), far surpassing publications on related topics. The sheer amount of scientific research on autism has no doubt been instrumental in many of the discoveries and insights so eloquently described by Happé and Frith (2020). But, as autistic scientist Michelle Dawson reminds us, quality matters too and, for that reason, it is a delight to recognise the contribution that both Happé and Frith have made, dramatically changing our understanding of autism in a host of ways.     

互联网形势下医院离退休干部管理工作探索

当前我国科技技术进一步提升,国民生活水平也在不断地进步,对于医院离退休干部管理服务的要求也越来越高。对于医院的工作来说,处理好医院的退离休老干部是一项十分重要的工作,所以医院工作管理人员需要提高对于离退休老干部管理工作的重视。而在传统意义下医院离退休干部的管理服务,存在着较多的问题,而当前在互联网的形势下却能够实现更加具有科学化、合理化的服务。通过创新服务理念,对于管理方式进行改革,可以有效地改善当前对于医院离退休干部的管理服务水平,青年团员可以自行组成相应的志愿者,加强对于退休老人的关心,了解老干部在生活以及学习中出现的问题,并且采取有效的措施进行解决。本文通过以阐述我国当前离退休干部管理工作的现状作为切入点,进行分析探究,进一步提出互联网模式下提高我国医院离退休干部管理的对应措施。     

吉林辽宁两省18年来的目标设置对突发公共卫生事件应急工作落实情况的关联研究

目的本研究立足于项目组前期研究的成果上，积极探索吉林辽宁两省目标设置水平的差异，并进一步探究受目标设置影响下的工作落实结果情况，探讨产生差异的原因。 方法以系统穷尽的方式收集吉林辽宁两省2000至2017年有关目标与工作落实情况的指标，利用Spearman相关和线性回归分析吉林辽宁两省目标设置对于突发应急工作落实情况的影响。 结果吉林辽宁两省突发应急领域的目标设置水平与工作落实情况总体均呈现上升趋势，截至2017年，吉林目标设置水平与工作落实情况分别为46%与60%，辽宁为60%与53.3%，且目标设置水平与工作落实呈正相关。 结论有公众需要为依据且定量可考的目标设置对于工作落实、推进、完善具有积极的正反馈作用，建立科学量化的突发应急目标设置评价体系是适宜可行的。     

妊娠期疾病类型与甲状腺功能异常相关性分析

目的研究妊娠期疾病类型与甲状腺功能异常相关性。方法回顾性分析2015年1月-2017年1月期间在天津港口医院治疗的107例孕妇,根据妊娠期是否患病分为A组、B组与对照组。A组为22例确诊为妊娠期糖尿病的患者;B组为36例确诊为妊娠期高血压疾病的患者;对照组为49例妊娠期血糖与血压正常、无其他疾病的孕妇。所有研究对象妊娠期定期抽取静脉血检测甲状腺功能、血压及血糖水平。采用妊娠期高血压疾病诊断标准、妊娠期糖尿病诊断标准以及妊娠期甲状腺疾病诊断标准联合评价。结果此研究发现糖尿病组与对照组在孕中期游离T4值、A组与对照组在孕晚期、B组与对照组在孕中期和孕晚期的促甲状腺激素(TSH)值对比,差异均有统计学意义(均P<0.05);3组孕妇不同妊娠时期临床甲状腺功能亢进、减退的发病情况各组别数据对比,差异无统计学意义(P>0.05);A组、B组与对照组在孕中期与孕晚期亚临床甲状腺功能减退发病情况数据对比,A组、B组与对照组在不同妊娠时期低T4血症发病情况数据对比,差异均有统计学意义(均P<0.05);孕早期仅甲状腺过氧化物酶抗体(TPOAb)阳性与甲状腺正常数据对比,B组发生率高于对照组、A组发生率低于对照组,差异均有统计学意义(均P<0.05)。结论与正常孕妇相比,妊娠期高血压疾病与妊娠期糖尿病患者在不同妊娠期的游离T4水平更低、TSH水平更高,且随着妊娠期的增长,变化趋势不断增大;妊娠期疾病类型与甲状腺功能异常存在着联系,妊娠期高血压疾病和糖尿病患者甲状腺功能异常发病率明显更高。     

某设备所致脉冲X射线辐射场测量与防护评价

目的 了解某设备实验条件下不同位置脉冲X射线电离辐射水平，提出适当的防护建议。方法 采用热释光测量方法，分别在设备舱周围不同方向不同距离布放热释光剂量计，累积一定数量脉冲辐射后进行测量；采用电离室型X、γ剂量率仪（FJ-347A）实时测量工作状态下不同距离处电离辐射剂量率水平。依据《电离辐射防护与辐射源安全基本标准》（GB18871—2002）规定的职业照射人员和公众个人剂量限值提出不同工作位辐射防护建议。结果 热释光剂量计累计接收3 000个脉冲辐射，设备舱外壁0.01～8.98 mGy，顶部0.01～15.67 mGy，距外壁1～12 m之间0.01～2.18 mGy，工作位0 mGy。工作状态下，X射线剂量率仪测得距设备舱外侧壁1～20 m之间空气比释动能率范围0.26～16 mGy/h。结论 热释光剂量计、电离室型剂量率仪测量结果基本一致，说明两种方法均可用于脉冲X射线测量；工作状态下设备舱外近距离处辐射剂量率较高，可通过采取防护措施或者限制人员工作量以满足辐射防护要求。
