关于生化分析仪检定若干问题的探讨

我们在生化分析仪检定过程中发现：生化分析仪检定规程（JJG464-1996）规定的检定项目绝大部分是适用于生化分析仪检定具体工作的，但规程中的波长准确度和波长重复性检定项目在具体操作时存在很大困难。文中提出修改检定规程的参考意见，并探讨了全自动生化分析仪检测中结合采用卫生行业质控标样的可行陛问题。     

用7081检定心脑电图机检定仪的定标电压

心电图机、脑电图机机内定标电压准确与否直接关系到其描记波形的质量，我们将心脑电图机检定仪（以下简称检定机）产生的定标电压信号和机内定标电压相比较，从而判断机内定标电压的优劣。所以我们可以毫不夸张地说检定仪定标电压量值为检定仪的一首要指标，对它的准确计量，对提高检定质量，减少误判，有着重要意义。ＪＪＧ７４９－９７规程叙述检定方法较简练，检定人员具体操作时有一定困难，现以数字表７０８１为例加以介绍。７０８１为八位半电压表，许多计量单位均以７０８１为主体建立检定检定仪的测量标准。规程规定了直流电压源及…

新旧《医生超声诊断仪超声源检定规程》的主要不同点

1999年3月1日开始实施的《JJG639－98医用超声诊断仪超声源检定规程》（以下简称新规程）是旧规程《JJG639-90》（以下简称旧规程）的修订版，本文详细介绍了新旧检定规程的主要区别和特点，以利于正确贯彻执行新规程。     

对血压计检定的分析与探讨

于1996年10月1日实施的《血压计和血压表试行检定规程》中第15条第3项关于基本误差检定步骤规定：“用压力发生器造压，使血压计或血压表和标准器的压力升高到最高检定点，然后降压逐点检定。对每个检定点，先从标准器的压力升高到最高检定点，然后降压逐点检定。     

CL-2500F型焦度计作标准器时的使用方法

日本拓普康公司的CL-2500F型焦度计刚被军内计量单位选作检定验光镜片箱的标准器。但是由于该机的使用说明书是针对测量普通眼镜片而写的,没有涉及到作为标准器时检定(验光镜片箱中的)标准镜片的方法。而JJG579-1998验光镜片箱的检定规程中所写的检定方法又是泛指所有焦度计的,

From the end of the world to the top of the world

I've been on the road a bit this summer. Because of the kind generosity of my London broker, Lloyd and Partners, Ltd., I've been allowed the unique opportunity to have an insider's view of the London market. I observed an interesting renewal situation and sat with underwriters in their boxes amid the hallowed (at least to us insurance geeks) trappings of Lloyd's. I spent several lovely days in Hanover with my long‐time lead reinsurer, Hanover Re, while trying desperately to keep up with my own work back home. It's been stimulating and thought‐provoking, and I know I won't ever view the purchase of insurance in the same way.     

社区医院脑卒中康复模式效果评估

目的探讨社区医院开展脑卒中康复、提高脑卒中患者的运动功能和日常生活活动能力（ADL）的模式。方法选择2006年8月-2008年8月住院脑卒中患者63例,采用随机对照研究方法,分为强化组32例,对照组31例,强化组采用系统的综合康复治疗;常规组给予临床基础药物治疗。分别于入选时、治疗1、2及3个月后对运动功能和日常生活活动能力（ADL）进行功能评定。结果两组患者在治疗前运动功能和日常生活活动能力（ADL）差异均无统计学意义（P〉0．05）,在治疗后3个月时强化组的运动功能和日常生活活动能力（ADL）与对照组相比较,差异有统计学意义（P〈0．01）。结论社区医院利用适宜技术开展脑卒中康复,对提高脑卒中患者运动功能和日常生活活动能力（ADL）有着极其重要的意义。     

从医方视角探解医患关系困境

目的：从医方视角探解医患关系困境。方法2013年10月-2013年11月,从本市几所主要医院中随机选择600例住院患者及医务人员进行研究。利用问卷调查法,对医患关系相关情况进行调查。结果调查发现,医务人员中有34.3％认为医患关系紧张,患者中有8.6%认为医患关系紧张。患方对医方不满的原因主要有沟通交流障碍和态度问题以及医疗质量问题等方面。结论面对医患关系的困境,医方需要积极的采取患者-医生-医院三位一体的应对策略,不断提高整体医疗质量,为患者提供人性化的医疗服务,努力改善医患关系。     

Appealing to the ''experience'' of the patient in the care of the dying

The care of dying patients in hospital is characterized by the copresence of four different frames: practical, medical, lay and psychological. Within the psychological frame, the staff define the patient as an experiencing subject, exposed to the staff members' knowledge and involvement. The psychological frame is used in two different circumstances. First, it is used by the staff members when the patient deviates from an expected identity within some other frame. The deviation creates a threat to the working conditions and moral order at the ward. The threat is managed through a shift into the psychological frame. Second, the psychological frame is used spontaneously in the accounts of their work given by staff members to the sociological field researcher. The image of care associated with the field researcher is characterized by a special awareness of the psychological issues. Thus the field researcher is inevitably a part of the functioning of the new kind of surveillance working through the psychological frame.     

Relationship of the clinician and the pathologist at the turn of the millennium

The autopsy, once a fundamental and familiar component of medical practice based on the good cooperation of clinicians and pathologist, is now infrequently used. Recent data indicate that autopsies are performed only about one third of the cases in Hungary and less that 1 of 10 inpatients death in the united States. Explanation for this decrease is multifactorial, involving changing professional and patients attitudes, the advent of sophisticated antemortem diagnostic methods, socioeconomic factors, and medicolegal concerns as well. Teaching institutions need to reevaluate concerning the need and practice of the autopsy. "The final audit" not always reflect well on clinical diagnoses and management of patients. Many facts proves that our modern tools still not enough to reach always a correct and safe diagnoses. Errors are still common in medicine. About 10% of necropsies indicate a clinical managements different from what the patients received, 20% reveal additional diagnoses, and 60% of cases have teaching point. Though autopsy is expensive and time consuming, moreover the shortage of pathologist is evident, necropsy should remain the cornerstone of medicine in the new millennium as well. There are a broad range of different fields where pathologist and clinicians should work together in an everyday--setting--e.g. evaluate biopsy- or cytology-samples. Clinicopathological conferences are also important to discuss cases mainly for teaching purposes. Without maintaining the traditionally good cooperation neither clinicians nor pathologists will be able to give proper answers to the challenges and professional questions of the new era.     

Metrological aspects of the study of physical characteristics of the air on the objects in the vicinity of the habitat

The paper considers the problems of measurement of air ions for settle the tasks of medical and environmental monitoring the habitat of various objects. It discusses the metrological assessment of the physical characteristics of the environment and the reasons for the insufficient use of aeroionometry in public health. The paper also compares the characteristics and specific features of the use of devices intended for study of air ion spectra. It shows it necessary to design the devices that measure air ions, which satisfy with the requirements that they measure accurately, are easy-to-use, rapidly operate.     

The relationship of the aims of the theory of Peplau with the care of the diabetic patient

In the face of the contextual amplitude of nursing activity, its theories need to be mediatated so to we be able to access the real meaning of the ideas elicited by theorists, and thus making possible to the nurses, consider and incorporate them into practice professional. In this article, we described the nursing theory developed by Hildegard Peplau still looking for to establish a connection of this theory with the way of caring of diabetic patient. The building of this study was worth of reflexion and it provided not just knowledge of theoretical ideas but mainly the urgency to use it (or to use another theory) in the environment of our daily practice of diabetic patient care.

Complete rupture of the tendon of the biceps muscle of the thigh

Complete rupture of the tendon of the M. biceps femoris proximal to its insertion is a rare occurrence. Relatively few patients have been recorded. We describe a patient with a complete rupture sustained as a result of a water skiing accident, viz. a fall over the stern wave. The case history was in accordance with a theory about the cause of this lesion--sudden overstretching of the hamstrings. The diagnosis was made by physical examination in the acute phase. With the patient in supine, 90 degrees flexed knees position and with isometric contraction of his hamstrings it is easy to mark and palpate a defect of the tendon just proximal to the caput fibulae. After operative reconstruction, a plaster cylinder was used for five weeks' postoperative immobilization. Five weeks after surgery, physical therapy was started, first to regain knee motion, and later to regain strength. Twelve weeks after surgery, the patient resumed working and recreational sports.
