基于“以学为中心”的医学微生物学课程教学改革与实践 总被引:1,自引:1,他引:0
“医学微生物学”是临床医学专业的核心课程,理论性和实践性较强。面向国家对医学人才培养目标的变化、如何在教学过程中以学为中心,以及注重学生能力素质的培养是本课程教学改革的重要环节。我们依据学情分析结果,通过翻转课堂、挖掘课程思政元素、基于问题的学习(problem-based learning,PBL)讨论课、虚拟仿真实验及临床见习课、开放性实验等教学手段综合运用进行课程的教学改革。实践证明,该教学改革体系使课程教学与医学人才培养挂钩,能够充分调动学生积极性、提高创新能力及服务意识,实现了师生共赢,圆满完成教学目标。 相似文献

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
