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。     

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。     

铸造支架联合NITI悬臂梁矫正舌倾下颌磨牙的临床效果评价

目的 评价NITI悬臂梁在矫正舌倾下颌磨牙中的临床效果。方法 选择16例单侧下颌第二磨牙舌倾的病例为研究对象,带垫铸造支架连接双侧下颌后牙,提供颌内支抗、解除咬合锁结,0.018英寸×0.025英寸或0.019英寸×0.025英寸NITI悬臂梁提供颊向旋转力矩和压低力。采用Graphpad Prism 6.0 软件对治疗前、后所测数据进行配对 t 检验。结果 所有患牙均获得直立,牙轴变化24°±1.2°（P<0.01）,近中舌尖到正中矢状面垂直距离变化（3±0.8） mm（P<0.05）,牙周状况良好,咬合关系稳定。结论 铸造支架联合NITI 悬臂梁可提供有效力学机制,矫正舌倾下颌磨牙。     

Framing the child at risk

Risk Assessment Reports are one form of accounting practice which delineate the space of risk considered in a child abuse neglect investigation. The paper analyses two Risk Assessment Reports, contrasting what is reported, what is directly observed and what is hypothesized and implied by child protection practitioners during the assessment of risk. From an analysis of these two reports (each 4 – 5 pages long), the paper identifies the rhetorical strategies and their realizations used by two practitioners in framing the child at risk. The paper problematizes the tension between the institutional need to constrain the exercise of professional judgement through Risk Assessment Models, and the extent to which practitioners actually localize the framing of risk to specific areas of investigation.     

Developing a model for clinical and basic science teaching skills

This report describes a model for identifying sets of teaching abilities considered to be effective for medical school teaching staff, based on roles teachers assume and functions they are expected to perform as instructors. The specification of these teaching abilities was the first step in the development of a comprehensive course on Medical Instruction at the Basic Institute of Medical and Agricultural Biology of the State University of Sao Paulo, Botucatu, Brazil, where the senior author is employed. The work was based on the assumption that medical school teachers are expected to assume a variety of teaching roles and that identification and specification of the abilities that define their roles can result in more effective and efficient teaching.     

同种异体骨支撑架微创治疗股骨头坏死的临床研究

目的应用改良髓芯减压术结合同种异体骨支撑架加自体骨和脱钙骨基质（decalcified bone matrix，DBM）治疗早期股骨头坏死，探索早期股骨头坏死的微创治疗方法。方法2004年1月～2005年4月，23例24个髋关节采用经大转子下通过股骨颈钻隧道至股骨头骨坏死区，将装有自体松质骨和DBM的同种异体骨支撑架经隧道拧入骨坏死区直至软骨下骨约5mm处，隧道远端用自体髂骨填塞。观察手术前后Harris评分变化、x线影像学表现及是否需进一步治疗。结果本组所有患者均获得随访，平均随访19（12—27）个月，以最后一次随访资料作为最终评价依据。Harris评分，术前优良率为43．5％（10／23）。术后优良率为91．3％（21／23）。22侧髋关节影像学表现保持稳定，无明显并发症发生。结论同种异体骨支撑架植入结合自体松质骨和DBM治疗成人股骨头坏死，增加了股骨头负重区软骨下骨的机械支撑，成骨作用强，有利于股骨头坏死的修复与重建，同时，不破坏患者股骨头本身的血液供应，创伤小，操作简单，值得临床推广使用。     

Stereotactic craniotomy and intraoperative lesion localisation using the Brown-Robert-Wells frame

Summary A simple technique of stereotactic craniotomy and intraoperative lesion localisation that uses the Brown-Robert-Wells (BRW) stereotactic frame is presented. The method optimises craniotomy placement and facilitates localisation of small intracerebral lesions. Using the system, 16 patients have had resection of intracranial neoplasms from deep and/or eloquent areas of the brain with no neurological morbidity.
