Toxicological evaluation of Yulangsan polysaccharide in Wistar rats: A 26-week oral gavage study

Although numerous studies have proven the medicinal values of Yulangsan polysaccharide (YLSP), the toxicity of this active ingredient is unknown. In the acute toxicity study, a single oral administration of 24 g/kg YLSP caused neither toxicological symptoms nor mortality, and the LD₅₀ was estimated >24 g/kg. In the chronic toxicity study, we administered doses of 0, 0.6, 1.2 and 2.4 g/kg YLSP in rats by oral gavage for 26 weeks followed by a 3-week recovery period. There was no mortality or remarkable clinical signs observed during this 26-week study. Additionally, there were no toxic differences in the following parameters: body weight, food consumption, hematology, clinical biochemistry, organ weight, and macroscopic findings. There were no adverse effects on histopathology observed in males or female rats treated with YLSP. Based on the results, the no-observed-adverse-effect-level of YLSP in rats is greater than 2.4 g/kg when administered orally for 26 consecutive weeks.     

冠心病心绞痛患者健康教育和心理护理效果

目的探讨对冠心病心绞痛患者给予健康教育联合心理护理干预后对其生活质量等方面产生的影响。方法选择我院2017年4月-2019年2月收治的100例冠心病心绞痛患者作为实验对象;抽签法分组后探究每组患者护理方式;对照组(50例):选择基础护理方式展开疾病护理;试验组(50例):选择基础护理+健康教育+心理护理方式展开疾病护理;对比各组患者表现出的护理工作满意度以及生活质量评定差异。结果试验组冠心病心绞痛患者护理工作总满意度(98.00%)高于对照组(82.00%)明显(P<0.05);试验组冠心病心绞痛患者睡眠情感、社会生活、精力以及躯体活动评分均高于对照组(P<0.05)。结论冠心病心绞痛患者在接受临床护理工作期间,对于护理工作满意度的提升,各项生活质量指标(睡眠情感、社会生活、精力以及躯体活动)评分结果的提升,均获得明显作用效果,最终对于冠心病心绞痛患者生活质量以及康复状态的显著提升,奠定基础。     

360度评价在住培学员岗位胜任力评价中的应用

目的运用360度评价对我院住培学员的岗位胜任力进行评价,对学员岗位胜任力的现状进行探讨分析。方法使用问卷调查表分别从专业基地教学主任、学员指导教师、同专业学员及学员本人的角度,对2017级222名住培学员的岗位胜任力进行360度评价,利用SPSS22.0对数据进行统计分析。结果连续两年的测评,住院学员8类岗位胜任力的自评和他评得分低于满分,学员在临床基本能力、医患沟通能力、掌握与运用医学知识、团队合作能力4项内容的评分,差异有统计学意义(P<0.05);同时学员在临床基本能力、医生职业精神与素质、医患沟通能力、掌握与运用医学知识、团队合作能力5项内容的评分较上一年相比,差异也有统计学意义(P<0.05)。结论调查结果提示360度评价可帮助住培学员提高岗位胜任力,后续培训应围绕调查结果和以岗位胜任力为导向来调整与设置,需增加人文属性内容的培训以及再量化培训测评内容、指标和进一步完善考评反馈机制。     

临床药师工作评价初探综述

随着我国医疗机构临床药师队伍的不断壮大，其在医疗服务中发挥着越来越重要的作用，对其工作进行绩效考核也是当今医疗领域的重要内容。以现有文献为基础，对国内外临床药师绩效考核体系进行分析，发现现有体系可分为为基于临床药师职责、基于临床药师业务流程、国外临床药师绩效考核体系三个方面；通过结合医疗机构的实际情况对现有绩效考核体系进行分析，发现存在考核指标和标准确定困难、考核难以做到实时性和延续性等问题，并针对这些问题提出清晰职责定位、重视临床药师价值体现等修改说明。     

预见习在精神病学教学中的作用研究

目的探讨预见习在精神病教学中的作用。方法选取120名本科学生,随机分为预见习组(n=60)和对照组(n=60)。预见习组在学习精神病学理论课程前一学期开始实施带教老师带领学生预见习、见习、实习全程教学,对比两组学生实践操作、理论知识成绩和学生满意度。结果干预后,导师制预见习组实践操作和理论知识成绩显著高于对照组(P<0.05)。导师制预见习组学生满意度显著高于对照组(P<0.05)。结论预见习教学有助于学生全面发展,提高精神病学教学水平。     

Impact and Predictors of Noncircular Left Ventricular Outflow Tract Shapes on Estimating Aortic Stenosis Severity by Means of Continuity Equations

Determining aortic stenosis (AS) severity is clinically important. Calculating aortic valve (AV) area by means of the continuity equation assumes a circular left ventricular outflow tract (LVOT). The full impact of this assumption in calculating AV area is unknown. Predictors of noncircular LVOT shape in patients with AS are undefined.In 109 adult patients with AS who underwent multiplanar transesophageal echocardiography, we calculated AV area by means of the standard continuity method and by a modified method involving planimetric LVOT area.We found 54 circular, 37 horizontal-oval, 8 vertical-oval, and 10 irregular LVOTs. Area derived by direct planimetry correlated better with the modified than the standard continuity method (r=0.89 vs r=0.85; both P=0.0001). Valve areas of patients with mild, moderate, or severe AS by planimetry were more often mischaracterized with use of the standard than modified method (29 vs 18; P <0.0001). Horizontal-oval AV area derived by planimetry (1.28 ± 0.55 cm²) was underestimated by the standard method (1.05 ± 0.47 cm²; P=0.001), but not by the modified method. Congenital AV morphology and low cardiac index were the only multivariate predictors of horizontal-oval shape. Low cardiac index was the only predictor of noncircular shape.More than half our patients with AS had noncircular LVOTs. Using the modified method reduces mischaracterizations of AS severity. Congenital AV morphology and low cardiac index predict horizontal-oval or noncircular shape. These data suggest the value of direct LVOT measurement to calculate AS severity in patients who have congenital AV or a low cardiac index.     

Fathers of children with autism spectrum disorder: Their perceptions of paternal role a predictor of caregiving satisfaction,self-efficacy and burden

BackgroundThe positive effect of a father’s involvement in children’s upbringing is now recognised. However, research on fathers raising children with autism spectrum disorder (ASD) are still few. This study examines the relationship between the perception, fathers of children with ASD have of the importance of their role in the development of their children and the feelings (self-efficacy, caregiving burden, satisfaction) they express about their parenting experience.MethodSixty-three Swiss Italian fathers of children with ASD completed The Role of the Father Questionnaire (ROFQ), three sub-scales of the Caregiver Survey, a subtest of the Child Adjustment and Parent Efficacy Scale and a home-made questionnaire measuring Perceived Social Support.ResultsThe results from hierarchical multiple regression analyses show that the importance that fathers attach to the paternal role predicts positively their caregiving satisfaction and their feeling of self-efficacy. The children’s challenging behaviours predict positively the caregiving burden whereas the assessment of social support predicts it negatively.ConclusionsThe perception of the importance of the paternal role needs to be considered in the support offered to families with a child with ASD. A better understanding of the fathers’ feelings could be of value for the programmes.
