Neuroblastoma (NB) is the most common extracranial solid tumor of childhood. It accounts for 8％–10％ of all malignant tumors in children[1] and results in a heavy burden to the life and health of children. NB is a complex disease, and its occurrence is related to exposure to environmental risk factors. Children of parents who are occupationally exposed to environmental endocrine disruptors (EEDs) such as paint have a significantly higher risk of NB[2]. Di-2-ethylhcxylphthalate (DEHP) is a widespread EED that can interfere with a variety of neurotransmitters, affect the differentiation, proliferation and migration of neurons, and cause damage to the nervous system, thereby increasing the risk of neurological tumors such as NB in children[3]. DEHP enters the human body, where it is metabolized into mono-2-ethylhexyl phthalate (MEHP). MEHP has been detected in human blood, breast milk, and urine. In a previous study, we found that MEHP promoted the proliferation of SH-SY5Y cells and upregulated matrix metalloproteinase-2 (MMP-2) and MMP-9 to promote the migration of SH-SY5Y cells[3]. However, the mechanism by which MEHP promotes the migration of SH-SY5Y cells remains unclear.

目的:通过三因素评分模型分析手术室轮班护士睡眠质量的影响因素.方法:采用匹兹堡睡眠质量指数(Pittsburgh sleep quality index,PSQI)对513名手术室轮班护士进行问卷调查.对所得数据进行三因素评分模型分析:因素1,睡眠效率;因素2,睡眠质量;因素3,日常生活功能障碍.结果:不同劳动关系、年龄、轮班工作经历的护士PSQI差异均有统计学意义(P<0.05～P0.05).多因素logistic回归分析结果显示,轮班经历为护士睡眠质量的独立影响因素(P0.05)外,其他各维度及三因素
目的:探讨家庭赋权护理对肝硬化失代偿期病人及家属的影响.方法:选取肝硬化失代偿期病人80例,按照随机数字表法分为对照组和赋权组,各40例.对照组实施常规护理,赋权组在常规护理基础上,应用家庭赋权护理干预.比较2组病人护理前后生活质量、心理状况和家属负荷、综合照顾能力.结果:干预后,赋权组病人汉密尔顿焦虑量表(HAMA)、汉密尔顿抑郁量表评分(HAMD)均低于对照组(P<0.01和P<0.05),生活质量各维度评分均高于对照组(P<0.05～P<0.01);赋权组病人家属照顾负荷各项评分均低于对照组(P<0
目的:分析国家自然科学基金(National Natural Science Foundation of China,NSFC)资助对省属医学院校高水平科研论文产出及其学术影响力指标的影响,为相关高校进一步提升高水平科研论文产出和学术影响力水平提供参考.方法:选取6所省属医学院校为研究对象,借助新一代InCites TM平台,对2011-2020年NSFC资助发表的高水平科研论文进行计量分析;采用Web of Science收录论文数、被引频次、论文被引百分比、h指数、引文影响力、被引次数排名前1％(10
目的:探讨专职护士程序化管理麻醉无菌耗材的应用效果.方法:选取麻醉医师自行准备手术所需的麻醉无菌耗材模式作为对照组(n=100);由专职护士程序化管理麻醉无菌耗材,于手术前30 min发放麻醉无菌耗材模式作为观察组(n=100),比较2组不同麻醉方式的无菌耗材准备时间、麻醉医师满意度、在岗率、耗材有效期合格率、漏费率.结果:观察组不同麻醉方式的无菌耗材准备时间、漏费率均明显低于对照组(P<0.01);观察组麻醉医师满意度、在岗率、耗材有效期合格率明显高于对照组(P<0.01).结论:专职护士程序化管理麻醉
随着近年来在细胞和分子水平对肿瘤认识的不断加深,肿瘤微环境在肿瘤发生、发展中的作用日益受到关注,与之相关的肿瘤治疗策略的不断更新改善,肿瘤微环境已逐渐成为医学领域的研究热点之一.肿瘤微环境最早于1993年提出,作为肿瘤发生,发展直接所处的环境,除为肿瘤提供基本生长条件外,还在肿瘤细胞耐药和抑制宿主免疫功能等机制中发挥重要作用[1].肿瘤发生早期时,微环境生化组分发生改变,极易形成乏氧状态,形成乏氧微环境;而乏氧微环境又在早期肿瘤恶化中扮演重要角色,促进肿瘤细胞加速增殖,产生耐药和免疫逃逸,甚至在肿瘤扩散、
