目的 了解哈尔滨市三级医院急诊重症监护室医疗资源配置现状,找出重症监护室存在的问题并提出相应对策。 方法 通过问卷调查方式获得2010—2012年间哈尔滨市三级医院急诊重症监护室床位、人员、设备等医疗资源配置情况的相关数据并进行统计分析。结果 研究数据显示,哈尔滨市5所三级医院的急诊重症监护室存在床位使用率不高、人员配比欠合理、人员工作强度过大、医疗设备配置不均衡等问题,严重制约了急诊重症监护室的发展。结论 哈尔滨市的急诊重症监护室取得了一定的发展,但在医疗资源配置方面仍存在一些问题;通过提高床位使用率、增加医护人员数量、调整人员结构、完善设备设施等手段可进一步优化医疗资源配置,提高急诊重症监护室的整体效率,满足学科发展需要。 相似文献

随着我国老龄化进程加快,医养结合在卫生政策与管理实践上已经成为普遍共识。现有研究主要从养老服务角度分析医养结合的概念、内涵以及实现路径,或从医学护理、医疗照护等方面探讨技术问题。医养结合模式,既不单纯是一种养老模式,也不单纯是一种医疗模式,而是医疗和养老融合的新模式,将改变传统的养老和医疗服务提供理念和方式,是解决我国老年人养老、医疗的创新之举,是建设健康中国的重要组成内容。本文从政策分析的角度出发,通过对医养结合概念的阐述、深入分析我国目前医养结合模式和存在的问题,提出政策建议。

In experiments on Black Sea skates (Raja clavata), the potential of the receptor epithelium of the ampullae of Lorenzini and spike activity of single nerve fibers connected to them were investigated during electrical and temperature stimulation. Usually the potential within the canal was between 0 and –2 mV, and the input resistance of the ampulla 250–400 k. Heating of the region of the receptor epithelium was accompanied by a negative wave of potential, an increase in input resistance, and inhibition of spike activity. With worsening of the animal's condition the transepithelial potential became positive (up to +10 mV) but the input resistance of the ampulla during stimulation with a positive current was nonlinear in some cases: a regenerative spike of positive polarity appeared in the channel. During heating, the spike response was sometimes reversed in sign. It is suggested that fluctuations of the transepithelial potential and spike responses to temperature stimulation reflect changes in the potential difference on the basal membrane of the receptor cells, which is described by a relationship of the Nernst's or Goldman's equation type.I.

Evolution of living organisms is closely connected with evolution of structure of the system of regulations and its mechanisms.
The functional ground of regulations is chemical signalization. As early as in unicellular organisms there is a set of signal
mechanisms providing their life activity and orientation in space and time. Subsequent evolution of ways of chemical signalization
followed the way of development of delivery pathways of chemical signal and development of mechanisms of its regulation. The
mechanism of chemical regulation of the signal interaction is discussed by the example of the specialized system of transduction
of signal from neuron to neuron, of effect of hormone on the epithelial cell and modulation of this effect. These mechanisms
are considered as the most important ways of the fine and precise adaptation of chemical signalization underlying functioning
of physiological systems and organs of the living organism 相似文献
