中医药调控IL-1治疗肿瘤机制的研究进展

炎症已成为影响肿瘤细胞增殖转移的第七大因素,而白细胞介素-1(IL-1)是炎性微环境的重要因子之一。中医药在治疗肿瘤时具有多途径、多靶点的优势,同时炎性微环境致病特点与现代中医学"癌毒"的理论相吻合。查阅近年中医药调控IL-1家族分子治疗肿瘤机制的文献,对其进行梳理,并做出概括及评价,从中医药主要调控IL-1α、IL-1β和IL-18因子治疗肿瘤展开综述,为中医药更系统化治疗肿瘤提供参考。     

Exploring Coverage of the 2008 Irish Dioxin Crisis in the Irish and UK Newsprint Media

The 2008 dioxin crisis occurred as a result of contamination of Irish pork. The event had significant implications for Ireland’s economy and the reputation of its agricultural industry, as well as raising concerns for human health. This study describes the results of a content analysis of Irish and UK newspaper coverage of the 2008 Irish dioxin crisis, as this is likely to provide insight into how public perceptions of this issue were shaped. Articles from 16 print publications were systematically sampled for the period December 2008 to February 2009. The resulting data set of 141 articles was examined using a coding protocol developed based on previous research and refined during piloting. Results indicated that the dioxin crisis was primarily portrayed by the media as an industry/economic crisis, dominant in 26.9% of articles in the sample. Within this dominant portrayal, the agricultural industry was frequently cited as being in crisis (42.6%); however, the implications of the crisis on the wider economic environment also received attention (17.7%). Differences between Irish and UK-based media were also examined, revealing that while the Irish media most frequently described the crisis in terms of its impact on the industry and economy, the UK media were more likely to portray the crisis as a risk to health. These dominant media messages and message framings have implications for the public understanding of the issue in each country and potential consequences regarding perception of the adequacy of existing food policy and regulatory oversight.     

HIV-negative children’s experiences and opinions towards parental HIV disclosure: a qualitative study in China

In HIV/AIDS research, few studies to date have evaluated ways to improve parental HIV disclosure practices using feedback from HIV-negative children who have recently experienced this event. We conducted semi-structured in-depth interviews with 20 children (aged 6–15) who were partially to fully aware of their parents’ HIV status in rural Guangxi, China. Of the 20 children, eight children who were of older age (11.38 years in average) endorsed parental HIV disclosure, five discouraged it and seven expressed uncertainty. Children’s different experiences and attitudes towards disclosure were seen to be associated with their family dynamics (especially the parent–child relationship), social support and care, experiences of stigma and discrimination, psychosocial suffering, comprehension of the disease and the children’s age. Our study contributes to building a child-centered comprehensive understanding for Chinese parental HIV disclosure. It is imperative that counselors and community advocates assess and help parents achieve optimal readiness preceding disclosure of their illness to their HIV-negative children.     

新冠疫情背景下组织学与胚胎学网络教学的实施及教学反思*

2020年1月,突发的新冠肺炎疫情给我国经济社会发展带来巨大的挑战,能否将信息技术和网络教学完美融合,确保网络教学的质量,是摆在每一位教育工作者面前的问题[1].按照国家关于新型冠状病毒肺炎疫情防控工作部署要求,遵循"停课不停教、停课不停学"的原则,在2020年春季学期面向本校中医学、针灸推拿学、临床医学等专业开设组织学与胚胎学课程的网络教学.组织学与胚胎学是医学院校中非常重要的专业基础课,与现代医学及生命科学相互交叉与渗透,该学科研究的是正常人体的微观结构及功能,具有教学内容多、知识点繁杂、专业术语多、教学学时偏少、学生学习难度较高等特点[2].

胃肠超声造影的临床应用价值

目的对比胃肠超声造影的优缺点,探讨对胃十二指肠良恶性病变的诊断符合率,评估胃肠超声造影的临床应用价值。方法选取200例有胃肠道症状患者的胃肠超声造影检查结果,与胃镜检查结果对比分析。结果胃肠超声造影对胃肠道疾病的诊断符合率为94.34%,特异度为100%,敏感度为94.12%,与胃镜对比,在胃十二指肠良恶性病变的检出率的差异无统计学意义(P>0.05)。结论口服胃肠超声造影剂对胃十二指肠结构性病变的诊断符合率高,且能有助于提高胰腺等腹膜后病变的检出率,有较好的诊断价值。应熟练掌握胃肠超声检查的适应证,规范扫查流程。
