不同运动素质青少年体格发育水平比较

目的了解高运动素质和低运动素质青少年的身体发育特点,为制定相应的干预措施提供依据。方法凡速度、爆发力、肌耐力、耐力跑和身体柔韧性均高于同性别、同年龄组均值为高运动素质,均低于同性别、同年龄组均值为低运动素质。对7~18岁高运动素质和低运动素质青少年进行筛检,比较高运动素质和低运动素质组青少年的身体发育水平。结果高运动素质青少年检出率男生为10.76%,女生为12.59%;低运动素质检出率男生为10.48%,女生为6.40%。高运动素质青少年体重、胸围、BMI显著低于低运动素质组,肺活量/体重指数显著高于低运动素质组;低运动素质组肥胖和超重检出率显著高于高运动素质组。结论高运动素质和低运动素质青少年的身体发育水平存在明显差别,肥胖和超重是造成运动素质下降的重要原因。     

浅谈如何构建和谐医患关系

从分析新形势下医患关系中的现状和存在的问题,结合我国医疗卫生工作的特点,就目前导致医患关系紧张的社会、医方、患方等因素进行归类和比较,以期发现改善目前医患关系的突破口。指出:要构建和谐医患关系,医院以人性服务为中心,寻找服务创新点;坚持社会效益准则,打造诚信医院;建立和完善医患沟通制度,促进医患沟通;提供精湛、优质的技术服务,让患者放心;严格医院质量管理,确保医疗安全;建立医疗告之制度,增进医患之间相互了解和信任;实现医院可持续发展。     

泌尿外科专科护士培训指标体系的构建

目的构建泌尿外科专科护士培训指标体系。方法2019年6—12月进行研究,首先成立研究小组,通过文献回顾、半结构式访谈初步构建指标体系,之后通过2轮Delphi专家咨询对指标进行修订,最终构建泌尿外科专科护士培训指标体系。结果构建的泌尿外科专科护士培训指标体系,包括一级指标3项,二级指标10项,三级指标48项。2轮专家的积极系数均为100%,2轮专家咨询的权威系数分别为0.856,0.903,2轮函询肯德尔和谐系数分别为0.302、0.337,差异具有统计学意义(P<0.001)。结论研究构建的泌尿外科专科护士培训指标体系具有可靠性及科学性,可作为评价泌尿外科专科护士培训的工具。     

助产士与准父亲导乐陪产共建模式在初产妇分娩中的应用研究

目的:观察助产士与准父亲导乐陪产共建模式在初产妇分娩中的应用效果。方法:选择2019年1月—2019年6月收入医院产科待产初产妇90例为研究对象,按照入院时间先后顺序分为对照组(2019年1月—2019年3月入院)与试验组(2019年4月—2019年6月入院)各45例,对照组接受常规助产护理,试验组接受助产士与准父亲导乐陪产共建模式干预,比较两组初产妇干预后焦虑抑郁评分、产时疼痛评分、总产程耗时、产后24 h出血量、自然分娩率、产后舒适度评分、分娩护理满意度评分与新生儿Apgar评分小于7分率。结果:试验组初产妇干预后焦虑抑郁评分、产时疼痛评分、总产程耗时、产后24 h出血量、新生儿Apgar评分小于7分率明显低于对照组,自然分娩率、产后舒适度评分与分娩护理满意度评分明显高于对照组(P<0.05)。结论:采用助产士与准父亲导乐陪产共建模式对初产妇施加干预,可明显改善初产妇焦虑抑郁情绪、减轻产时疼痛、推进产程进展、提高自然分娩率、改善母婴结局、提升产后舒适感,深受初产妇认可。

Comparative Evaluation of Compressive Strength and Flexural Strength of Conventional Core Materials with Nanohybrid Composite Resin Core Material an in Vitro Study

Several dental materials have been used for core build-up procedures. Most of these materials were not specifically developed for this purpose, but as a consequence of their properties, have found application in core build-up procedures. Improvements in composites and the development of nanocomposites have led to their use as a core build up material due to their superior mechanical properties, optical properties and ease of handling. However it is not clear if they have better mechanical properties than the conventional core build up materials like amalgam, GIC and dual cure composite core build up material. The strength of the core material is very important and this study was undertaken to compare the mechanical properties of materials used for direct core foundations. The differences between the compressive strength and flexural strength of Filtek Z350 nanocomposite with conventional core build up materials like Amalgam, Vitremer GIC and Fluorocore were tested. Cylindrical plexi glass split molds of dimension 6 ± 1 mm [height] x4 ± 1 mm [diameter] were used to fabricate 15 samples of each core material for testing the compressive strength and rectangular plexi glass split molds of dimension 25 ± 1 mm [length] x 2 ± 1 mm[height] x2 ± 1 mm [width] used for fabricating samples for flexural strength. The samples were stored a water bath at 250 °C for 24 h before testing. The samples were tested using a Universal Instron testing machine. The results of the study showed that Fluorocore had the highest compressive strength and flexural strength followed by Filtek Z350 [nanocomposite] Amalgam had the least flexural strength and Vitremer GIC had the least compressive strength. Thus flurocore and nanocomposite are stronger than other core build up materials and hence should be preferred over other conventional core build up materials in extensively damaged teeth.
