呼吸专科护士慢性呼吸疾病管理现状调查

目的调查呼吸专科护士慢性呼吸疾病管理现状,为提高慢性呼吸疾病的管理水平提供参考。方法依据《中国成人慢性呼吸疾病患者护理管理指南》设计调查问卷,对重庆、四川、贵州、陕西、河北、湖北、海南7省市的205名呼吸专科护士进行问卷调查。结果呼吸专科护士慢性呼吸疾病管理总分为(140.72±23.90)分。慢性呼吸疾病管理得分最低的3个条目有评估工具应用、个性化管理计划的实施、慢阻肺随访的次数及指导哮喘患者使用峰流速仪;呼吸专科护士所在单位慢性呼吸疾病管理平台建设均低于50%。结论呼吸专科护士慢性呼吸疾病管理处于中等偏下水平,评估是慢性呼吸疾病管理的薄弱点。需加强呼吸专科护士专业能力培养,规范慢性呼吸疾病全程管理,强化医院平台建设等,提高慢性呼吸疾病的管理水平。     

某医学期刊送审论文的统计学问题分析

<正>医学科研论文大多涉及数据收集和统计分析,正确合适的数据统计分析方法,才可能保证科研结果的正确性。虽然论文撰写的国际规范对数据统计学分析有明确的要求,科研人员也学习过医学统计学,但如何正确选择统计分析方法,准确描述统计分析结果,仍然是很多科研人员比较困惑的问题。有些作者在论文中误用、错用统计学方法,直接影响研究结果的可信度,导致论文质量不高或者结论错误[1-3]。本文对某杂志2014年至2015年度送审论文中的统计学问题进行分析,旨在帮助作者避免类似的错误,提升科研论文质量。资料与方法     

卫生职业教育中强化护生职业素质培养的途径

卫生职业教育的根本目的就是培养适应时代需要、符合职业要求的合格的护理工作者，这就要求在教育过程中突出时代特点、突出职业培养目标，运用全新的教育方式使护生明确职业素质要求，树立和培养正确的护理观念，通过有效的教育途径保证培养目标的实现。     

早期干预对高危儿在婴儿早期发育的影响

目的：探讨早期干预对高危儿在婴儿早期发育的影响。方法：采用自行设计的一套早期干预方法通过指导家长对实验组实施，分别在3个月、6个月时进行格体生长和行为发育的评估，另设对照组进行比较。结果：实验组和对照组在体重、身长、头围方面均无统计学差异，但实验组的5个能区行为发育商均值都高于对照组，除3个月的语言能区外，其余均有统计学差异。结论：早期干预在婴儿早期就能促进高危儿的行为发育，但对促进高危儿的体格生长无明显效果。     

Two Novel Pyrrolopyrimidine Lipid Peroxidation Inhibitors U-101033E and U-104067F Protect Facial Motor Neurons Following Neonatal Axotomy

Recent reports suggest that oxygen radical-induced lipid peroxidation plays a role in the retrograde degeneration of motor neurons following facial nerve axotomy in the neonatal rat. The purpose of the present study was to explore this notion further by testing the neuroprotective properties of two novel brain-penetrating, lipid peroxidation inhibitors, U-101033E and U-104067F, in this model of neuronal degeneration. In Experiment 1, 14-day-old rats were pretreated with 3, 10, or 30 mg/kg U-101033E (po) 10 min before right facial nerve axotomy (Day 0) and then posttreated once a day from Day 1 to Day 6, and once every other day from Day 8 to Day 21. Rats were sacrificed 21 days postaxotomy and surviving cholinergic cell bodies were identified using choline acetyltransferase immunocytochemistry. Both 10 and 30 mg/kg U-101033E significantly enhanced motor neuron survival, with survival rates of 65.9–88.9% being noted in comparison to 51.7–62% survival in vehicle controls (P ≤ 0.05). Experiment 2 demonstrated a significant neuroprotective effect of 10 and 30 mg/kg U-104067F using the same dosing schedule. Experiment 3 was designed to test whether shorter periods of drug exposure (e.g., 5 or 7 days) would be sufficient to preserve motor neurons in rats treated with 10 mg/kg U-101033E. The results suggested that as little as 5 days of drug treatment is sufficient to enhance motor neuron survival. Finally, Experiment 4 demonstrated an 18–19% increase in motor neuron survival in rats treated with 10 and 30 mg/kg U-104067F for 5 consecutive days postaxotomy. Taken together, the attenuation of motor neuron degeneration by the two pyrrolopyrimidine lipid peroxidation inhibitors, U-101033E and U-104067F, lends support to the notion that lipid peroxidation contributes to the pathogenesis of axotomy-induced neurodegeneration.
