目的:观察应用目标策略性干预的婴幼儿消化道出血患儿护理质量评价指标的建立与应用效果。方法:前瞻性选择2019—2021年儿科诊治的消化道出血婴幼儿166例作为研究对象。依据随机数列表法将所有病人分为对照组(常规护理干预)和观察组(行护理质量评价指标下的目标策略性干预),各83例。比较2组总有效率、出血停止时间、输血量、再出血率、住院时间及护理前后血红蛋白水平(Hb)、血细胞比容(Hct)水平、患儿家长不良情绪和护理满意度。结果:观察组总有效率高于对照组(P<0.05)。观察组出血停止时间、输血量、再出血率、住院时间均小于对照组(P<0.05)。护理3 d后,2组Hb、Hct水平均高于护理前(P<0.05),观察组Hb、Hct水平均明显高于对照组(P<0.01)。护理3 d后,2组患儿家长SDS评分与SAS评分均高于护理前(P<0.05),观察组SDS评分与SAS评分均明显低于对照组(P<0.01);观察组基础护理、护理安全、病房管理、护理文书在内的护理质量评分均明显低于对照组(P<0.01)。观察组护理总满意度高于对照组(P<0.05)。ROC曲线结果显示,护理总有效率+不良情绪+护理质量+护理满意度,四者联合用于评价目标策略性干预对婴幼儿消化道出血患儿护理质量的ROC为0.671,Cut-off值为2.003,灵敏度1.000,特异度0.275,阳性预测值0.525,阴性预测值1.000,约登指数0.275(P<0.05)。结论:目标策略性干预护理模式可提高婴幼儿消化道出血整体治疗有效率,促进患儿早期出血停止,降低二次出血率,改善贫血状态,缓解患儿家长的不良情绪,极高整理护理满意度。目标策略性干预护理模式临床应用优势明显。

Background: Three-dimensional (3D) fusion imaging has been proved to be a promising neurosurgical tool for presurgical evaluation of tumor removal. We aim to develop a scoring system based on this new tool to predict the resection grade of medial sphenoid wing meningiomas (mSWM) ***: We included 46 patients treated for mSWM from 2014 to 2019 to evaluate their tumors'' location, volume, cavernous sinus involvement, vascular encasement, and bone invasion by 3D multimodality fusion imaging. A scoring system based on the significant parameters detected by statistical analysis was created and ***: The tumor volumes ranged from 0.8 cm3 to 171.9 cm3. A total of 39 (84.8%) patients had arterial involvement. Cavernous sinus (CS) involvement was observed in 23 patients (50.0%) and bone invasion was noted in 10 patients (21.7%). Simpson I resection was achieved in 10 patients (21.7%) and Simpson II resection was achieved in 17 patients (37.0%). Fifteen patients (32.6%) underwent Simpson III resection and 4 patients (8.7%) underwent Simpson IV resections. A scoring system was created. The score ranged from 1 to 10 and the mean score of our patients was 5.3 ± 2.8. Strong positive monotonic correlation existed between the score and resection grade (Rs = 0.772,P < 0.001). The scoring system had good predictive capacity with an accuracy of 69.60%.Conclusions: We described a scoring system that enabled neurosurgeons to predict extent of resection and outcomes for mSWM preoperatively with 3D multimodality fusion *** registration: Retrospectively registered

本文选择2013—2017年沪深A股上市企业为研究对象,利用其经验数据对营改增背景下税负转嫁能力和金融关联对企业现金持有这一财务策略的影响进行实证分析。研究发现:在营改增背景下税负转嫁能力和管理层金融关联均能显著降低企业的现金持有量;同时管理层金融关联在税负转嫁能力和现金持有量的关系中起到了挤出效应,即金融关联显著削弱了税负转嫁能力对企业现金持有量的抑制作用。本文的研究可为营改增背景下企业现金持有水平的合理化提供借鉴,并提升企业资本配置效率。

针对单一的分类器用于旋转机械故障诊断时存在准确率不高的问题,提出一种基于随机森林算法的旋转机械齿轮组故障诊断方法。该方法利用随机森林多分类器组合决策树的思想,通过多分类器的组合学习提高故障诊断的准确率,并在风力涡轮动力传动系统故障诊断模拟器系统上进行了多工况多故障的实验验证。首先,收集多工况、多故障的齿轮传感器信号,提取传感器信号的时域特征作为随机森林的输入特征量。然后,利用构建好的随机森林模型进行齿轮组的故障诊断,并将随机森林算法的分类结果与支持向量机方法的分类结果进行对比。通过对故障诊断结果的分析,随机森林算法避免了复杂的寻参过程和传统分类器的过拟合现象,能够处理大规模数据集,通过分类器的组合,提高了故障诊断准确率,并缩短了分类模型的预测时间,具有较好的应用前景。

微波宽带超材料吸波器可以实现武器装备的隐身,对现代化战争有着十分重要的意义。针对目前宽带吸波器入射角度不敏感性仍需要提升的问题,提出了一种在磁性介质表面制备超表面结构的宽带超材料吸波器结构。结构由周期性金属结构层、磁性介质层、金属反射底板层三层结构结合而成。仿真结果表明,在8~15 GHz(相对带宽为61%)频带内,吸波器结构实现了90%以上的吸收率。当电磁波斜入射时仍具有良好的吸收性能,尤其在横磁模式下,当入射角为60°时,在8~15 GHz频率范围内,吸收率仍能保持90%以上,表现出了优异的广角吸收特性。所提出的吸波器结构满足目前对超材料“薄,宽,轻,强”的要求,在军事和工程领域有一定应用价值。
