基于中医古籍文献的升降散应用溯源及探析

通过对中医古籍中有关升降散论述的文献梳理,全面探讨其内涵。本方是在大黄、僵蚕为雏形的基础上增加蝉蜕、姜黄而成方,几经易名,终在杨璿《伤寒瘟疫条辨》中为后人所熟知。本方广泛用于治疗瘟疫,以丸剂、散剂为主,方便携带,便于服用;重用大黄旨在祛邪、逐秽;应用时视人之体质强弱和量其毒之轻重而判断用药多寡,并辅以米酒、生蜜等以顾护正气。杨璿将其由治疗“热疫”的专方扩展为治疗“表里三焦大热”的通用方剂,扩大了本方治疗疾病范围。     

Efficient Denoising Framework for Mammogram Images with a New Impulse Detector and Non-Local Means

Objective: The survival rates of breast cancer are increasing as screening and diagnosis improve. The removal of noise is revealed to be a significant step for automatic - computer aided detection (CAD) of microcalcification in digital mammography. Methods: In this paper, a combined approach for eradicating impulse noise from digital mammograms is proposed. The process is achieved in two stages, detection of noise followed by filtering of noise. The detection of noise is carried out by using Modified Robust Outlyingness Ratio (mROR) trailed by an extended NL (Non-Local)-means filter for filtering mechanism. Results: According to the value of mROR, all pixels in mammogram images are divided into four distinct groups. In each cluster, many decision rules are then applied for detecting the impulse noise. Filtering is done with NL-means filter by providing a reference mammogram image. Conclusion: The comparative analysis and evaluated results are compared with some existing filters which indicate that the proposed structure outperforms the analysed result of others.     

情景模拟联合案例讨论在急诊护理临床带教中的应用体会

目的探究急诊护理临床带教中采用情景模拟、案例讨论联合教学法效果。方法在本院实习的若干名护生中,选取124名护生分按照教学方法分组,对照组62名实施传统急诊护理带教,观察组62名实施案例讨论、情景模拟联合教学法,对比临床带教效果。结果两组实践与理论成绩相比,观察组成绩更高(P<0.05)。思维、急救及应激能力自我评价相比,观察组的总提高率高于对照组(P<0.05)。实施案例分析结合情景模拟教学模式后,问卷调查中观察组无护生不赞同此模式,非常赞同此教学模式的护生占总人数的90%以上。结论实施案例讨论、情景模拟联合教学模式后,护生急诊护理实践与理论水平均提升,护生我评价较高。     

四妙勇安汤方源探析

四妙勇安汤由金银花、玄参、当归、甘草4味药物组成,为《古代经典名方目录(第一批)》中100个经典名方之一。经溯源发现,四妙勇安汤源于《石室秘录》,后由《古今图书集成·医部全录》《验方新编》等书引用。从古代文献记载来看均有方无名,"四妙勇安汤"之名,最早见于1956年《中医治疗动脉栓塞性坏疽症的成效》,是由当时记者吕民报道河北省释迦宝山用"四妙勇安汤"治疗当地的动脉栓塞性坏疽时冠名。四妙勇安汤从方药组成与剂量上看,从《石室秘录》开始即是"金银花三两,当归二两,生甘草一两,玄参三两",历代版本《方剂学》确定四妙勇安汤金银花、玄参、当归、甘草的比例就是3∶3∶2∶1。而查阅文献,释迦宝山临证所用的四妙勇安汤由"玄参132 g,当归99 g,银花66 g,甘草33 g"组成,金银花、玄参、当归、甘草的比例变成2∶4∶3∶1。从治疗时间上看,原方记载的7日愈或是10日愈,而释迦宝山将其用到了三四个月,甚至五六个月。研究认为,古籍中的四妙勇安汤,应该是用于疾病的初期,尽早发现和治疗;而释迦宝山修改过的剂量,是广泛用于脱骨疽的中后期,甚至出现坏疽的严重病情所使用的,因此服药时间长,剂量大。且四妙勇安汤临证不仅限于治疗脱骨疽,也用于大头疮等,现代该方的使用已经大为拓展。相关研究已证实四妙勇安汤具有抗炎、稳定斑块、降脂、保护血管、改善血液流变学、抗凝、抑制血栓形成和促纤溶等作用,后续应开展君臣佐使辨析,对其临床应用范围重新进行界定。     

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。     

A conceptual model and detailed framework for stress-related,strain-related,and overuse athletic injury

A multitude of athletic injuries occur when the various tissues that make up the human body experience stresses and strains that exceed their material strength. The precise amount of stress and strain that any given tissue can withstand is determined by the mechanical properties and resultant strength of that particular tissue. These mechanical properties are directly determined by an individual’s physiology and acute regulation of these properties. A number of theoretical frameworks for athletic injury occurrence have been proposed, however, a detailed conceptual framework for injury aetiology that considers the interplay between the physiological and mechanical factors and outlines the causal pathways to tissue damage and injury is needed. This will guide injury research towards a more thorough investigation of causal mechanisms and understanding of risk factors. Further, it is important to take into account the considerable differences in loading patterns which can result in varying injury outcomes such as acute stress-related, strain-related, or overuse injury. Within this article a simplified conceptual model of athletic injury is proposed along with a detailed, evidence-informed, conceptual framework for athletic injury aetiology that focuses on stress-related, strain-related, and overuse injury.
