根据教研室工作考核评价的原则,利用层次分析法(AHP)构建教研室工作考核评价的层次结构模型,确定指标的权重系数。然后,将多目标决策中的理想解法应用到以矩阵为元素的空间中,按照与最小理想点的相对接近度对人才培养作出综合评价。最后,通过对实例进行量化计算,实证研究表明评估结果与实地调研具有良好的一致性,同时说明了该算法的有效性。

目的分析极早产儿(VPI)发生支气管肺发育不良(BPD)的危险因素,为防治VPI BPD提供科学依据。方法采用前瞻性多中心研究方法,收集国内7个地区28家医院新生儿科2019年9月至2020年12月收治VPI的临床资料,根据生后28 d是否持续氧依赖分为无BPD组和BPD组,分析VPI发生BPD的危险因素。结果纳入符合标准的VPI 2514例,无BPD组1364例,BPD组1150例,BPD发病率45.7%;出生胎龄、体重越小,BPD发病率越高(P均<0.001)。与无BPD组比较,BPD组患儿平均出生胎龄、体重、剖宫产率较低,男婴、小于胎龄儿、5 min Apgar评分≤7分发病率较高(P均<0.01)。BPD组新生儿呼吸窘迫综合征(NRDS)、合并血流动力学改变的动脉导管未闭、需干预的早产儿视网膜病、喂养不耐受、宫外生长发育迟缓、Ⅲ~Ⅳ级颅内出血、贫血、早发和晚发败血症、院内感染、静脉营养相关性胆汁淤积症发病率较高(P均<0.05),肺表面活性物质使用、激素暴露、贫血且需输血的比例较高,有创和无创机械通气时间、用氧时间及总住院时间较长(P均<0.001)。BPD组的开始肠内营养时间、累计禁食天数、达全肠内营养日龄、肠外营养持续天数、总热卡达110 kcal/(kg·d)日龄、口服热卡达110 kcal/(kg·d)日龄均大于无BPD组,母乳喂养率低于无BPD组(P均<0.001)。住院第1周氨基酸、脂肪乳累计剂量BPD组较高(P均<0.001)。多因素Logistic回归分析显示,NRDS、有创机械通气、达全肠内营养日龄、贫血且需输血是VPI发生BPD的独立危险因素,出生胎龄较大是BPD的保护因素。结论加强围生期管理,避免早产和严重NRDS发生,缩短有创机械通气时间,重视肠内营养管理,尽快达全肠道喂养,严格掌握输血指征,对于降低VPI BPD的发病率至关重要。

2019新型冠状病毒(2019 novel coronavirus,2019-nCoV)感染的肺炎,因2019年12月发生在武汉的不明原因病毒性肺炎病例而被发现,并于2020年1月12日被世界卫生组织(World health Organization,WHO)命名。在之后的一个月时间内,2019-nCoV在湖北省内外甚至其他国家传播造成了数以千计的病例出现,同时也引起了民众一定程度的恐慌。本指南的制订希望能够从疾病流行病学、病因学、诊断、治疗、护理、医院感染控制等方面给临床医生、社区居民等提供医疗护理及居家照护相关指导。

A search for the doubly charmed baryon ■^+cc is performed through its decay to theΛ^+c K^-π^+ final state,using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7,8 and 13 *** data correspond to a total integrated luminosity of 9 fb^-*** significant signal is observed in the mass range from 3.4 to 3.8 GeV/c^*** limits are set at 95%credibility level on the ratio of the ■^+cc production cross-section times the branching fraction to that ofΛ^+c and ■^++cc *** limits are determined as functions of the ■^+cc mass for different lifetime hypotheses,in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 4 to 15 GeV/c.
