The coronavirus disease 2019(COVID-19)outbreak poses a serious challenge to China and most countries around the world,thus the World Health Organization has declared the outbreak a public health emergency of international concern.On August 24,2020,more than 23,584,000 cases of COVID-19 had been confirmed in more than 120 countries/regions worldwide,812,519 patients had died,and 16,078,455 confirmed cases were still undergoing treatment.Most patients with COVID-19 have a good prognosis,but a small portion of patients become critically ill and even die(the cumulative mortality rate is～3.7％).Critically ill patients account for～15％of those with COVID-19,and most of them are the elderly,patients with underlying diseases or patients with obesity[1].Critically ill patients often experience dyspnea and/or hypoxemia 1 week after onset of the illness,and in severe cases,the patient can rapidly develop acute respiratory distress syndrome(ARDS),septic shock,uncorrectable metabolic acidosis,bleeding and coagulation dysfunction,and multiple organ failure.According to our clinical treatment experience,we previously proposed the“Huashan Model”,which is based on supportive therapy for multiple organs supplemented with anti-inflammatory and anticoagulation therapies,for the treatment of patients with severe novel coronavirus pneumonia(NCP)[2].This model significantly improved the survival rate of critically ill NCP patients by correcting the pathophysiological state,adjusting immune system function,and promoting clearance of the virus and affected cells through symptomatic and supportive treatment.Patients with severe NCP in the convalescent stage often experience serious complications,such as multiple organ failure.In particular,prevalent pulmonary parenchymal lesions,alveolar lumen exudates,and pulmonary interstitial fibrosis can lead to poor pulmonary function in patients and seriously affect their long-term quality of life.Therefore,alleviating/reversing the process of pulmonary interstitial fibrosis,improving the pulmon-ary function of patients with severe NCP,and improving the quality of life of patients should be the focus of treatment for patients with severe NCP in the convalescent stage.

产后护理是妇女保健工作重要组成部分,产妇分娩需长时间的用力,极易损伤盆腔、膀胱神经,并且随着时间延续可能导致神经肌肉麻痹而导致尿潴留[1-2].尿潴留指的是产妇生产后6～8 h内出现的尿不尽症状,会引发尿路感染,严重时产妇长时间难以排出膀胱内的尿液,直接影响子宫的收缩进展,由此引起产后出血、死亡的案例较多[3-4].与此同时,产后尿潴留还会造成产妇心理波动,导致产妇产生明显的负面情绪,因此对于产妇产后的护理工作应当予以重视[5].本文分析安徽省妇幼保健院产三科近2年内分娩的60例产妇传统护理与预防性护理对

每年的6月,都是中国人的“高考月”,莘莘学子于6月初考试,6月末填报影响一生职业规划的志愿.疫情期间,医务人员正能量的释放,使医学成为最近两年众多热门报考专业之一.向往成为医生的学子们要认识到,学医、行医之路充满了坎坷、艰辛,且医学模式正在面临深刻的转变,只有参透医学的本质,对健康和疾病的认识逐步全面、透彻和科学,才能成为一名真正的医者.
近期,几起医疗行业“内部爆料”事件,使得公众对于看病就医那些事有了更多关注和议论:先是山西省大同市某三甲医院医生自曝受贿50万元,后有北京大学第三医院医生张煜知乎账号发文,呼吁遏制肿瘤治疗中的不良医疗行为,再有郑州一医生举报两名科主任“私自替换手术骨科螺钉,点名要收40％回扣”.
以突发公共卫生事件应急处置立法为起点进行探寻,深入结合突发公共卫生事件应急处置的现状,着重以突发公共卫生事件应急处置治理方式、政府应急处置制度、生物安全以及生命健康权、知情权与隐私权的四个方面,分析我国突发公共卫生事件应急处置所面临的法律困境,并针对此困境提出立法建议:强化法治的方式、政府的治理能力及建设能力、生物安全和个体权益的保障,以期推动我国突发公共卫生事件应急处置相关法律的完善.
为有效预防医疗保险基金欺诈,维护医保基金的正常运行,提出针对性的防范对策,通过归类与梳理国家医保局公开的24起骗保案例,总结骗保的形式,剖析发生原因.其中,骗保主体主要分为单一主体和复合主体,单一的骗保主体主要有定点零售药店、定点医疗机构,一般采取过度医疗、编造虚假住院信息、虚记诊疗费用等手段骗保;复合主体的骗保以医患共谋这一形式为主,骗保手段主要有诱导住院、挂床住院、串换诊疗项目等.我国可以引入第三方监管机制,对医保基金进行专业化监管;并建立相关利益方双向约束机制,防范医患共谋案件的发生.
