目的分析女性压力性尿失禁盆底肌训练执行现状及其影响因素。方法选取2019年10月至2020年10月于郑州大学第三附属医院妇科就诊的94例压力性尿失禁患者为研究对象,采用问卷调查法对盆底肌训练执行现状进行调查,根据调查结果将患者分为执行组与未执行组,并对其影响因素进行分析。结果94例压力性尿失禁患者中,执行盆底肌训练的有41例(43.62%),未执行盆底肌训练的有53例(56.38%)。单因素分析显示,年龄、最高受教育程度、分娩方式、体重增长、当前是否存在尿失禁与盆底肌训练执行现状相关(P<0.05);多因素logistic回归分析显示,体重增长(P=0.013,OR=2.855,95%CI:1.244~6.554)、存在尿失禁(P=0.001,OR=3.710,95%CI:1.718~8.013)是盆底肌训练执行现状的独立影响因素。结论压力性尿失禁患者的盆底肌训练执行欠佳,体重增长、存在尿失禁是其独立影响因素,应积极进行有效护理干预措施,提高压力性尿失禁患者盆底肌训练的执行率。

目的探讨不同QT间期校正公式应用于不同心率范围的校正效果。方法从公共信息平台ECG-ViEW心电图数据库中筛选出心率跨度在30~200次/min的心电图699778份,根据心率分成30~60、60~100、100~150及150~200次/min共4组。分别以Bazett、Fridericia、Framingham及Hodges公式校正QT间期。分析在不同心率范围内及采用不同公式的情况下,QTc与心率及测定QT间期值间的线性关系。结果未经校正的QT间期随心率的减慢而延长,Bazett公式对QT间期校正效果不佳,尤其是对心率过慢者。Hodges公式在低心率心电图中校正效果较好,而在快心率心电图中校正效果不佳;Fridericia公式和Framingham公式在正常及快心率心电图中的校正效果较好。结论临床常用的Bazett公式在QT间期校正方面存在一定的缺陷,Hodges公式对低心率患者更具实用价值,Fridericia公式和Framingham公式更适用于校正正常及快心率心电图中的QT间期。

目的调查护士对肿瘤患者生育力保存的认知及参与情况,并分析其影响因素,以期为促进生育力保存的临床开展提供借鉴。方法2022年10—11月选取郑州市2所妇幼专科医院妇科、产科、生殖医学科、血液科等涉及生育力保存措施相关科室的临床护士450名,收集并分析其性别、年龄、科室、职称、层级、受教育程度、婚姻及生育状况、护理工作经历等资料,采用logistic回归分析探讨护士参与肿瘤患者生育力保存的影响因素。结果有效回收问卷431份(95.8%),共有123名(28.5%)护士表示曾向肿瘤患者推荐过生育力保存,仅116名(26.9%)护士参加过生育力保存相关内容的培训;护士对自身参与生育力保存认同度得分总分为(74.53±12.39)分;护士认为自己参与生育力保存的促进因素主要是“患者主动提出了生育力保存相关问题”(85.4%)、“我需要为患者提供健康教育”(77.0%),主要阻碍因素是“我缺乏生育力保存相关专业知识”(77.7%)、“和患者进行生育力保存讨论使他/她想起病情、引起不适”(68.9%)。logistic回归分析结果显示,是否参加过生育力保存相关培训、是否专科护士、从事护理工作年限、年龄、生育力保存重要性认同度为护士向肿瘤患者推荐生育力保存的影响因素。结论护士在肿瘤患者生育力保存中参与度不高,认同度处于中等偏上水平,是否专科护士、从事护理工作年限、年龄、生育力保存重要性认同度以及是否参与过生育力保存培训是影响护士向肿瘤患者推荐生育力保存的因素。

In this paper, the problem of sliding mode output feedback for a class of continue-time Markov jump systems with some unmeasured states is investigated. An observer is designed to estimate the system states, and a sliding mode controller is synthesized for driving the system to reach to and maintain on the sliding mode. Sufficient conditions for the existence of the controller under which the underlying system are stochastically stabilized are derived via LMIs. A numerical example shows the validity and potential of the developed results.
