RESUMO
Vertigo is one of the most common symptoms in general practice. During the standardized training in theory and practice of vertigo diagnosis and treatment, researchers from group of vertigo subspe-cialty of department of neurology analyzed the epidemiological characteristics of vertigo disease and the present teaching situation of theory and practice teaching. They put forward and adopted the "Three Steps"(laying firm foundation, consolidating and strengthening, and improving skills) which is based on multidis-cipline and conforming to trainees' understanding of the disease. It helped general practitioners tofamiliarize themselves with the etiology, diagnosis, and treatment of vertigo, to perfect their multidisciplinary knowl-edge structure, to establish scientific clinical thinking, and to improve their levels of the diagnosis and treatment of diseases relating to vertigo, which has produced good effects and has been playing an important role in improving the prognosis for vertigo patients.
RESUMO
The purpose is to establish an emergency medical system that covers a certain region, responds quickly, operates efficiently, functions perfectly and develops sustainably. Such a system leverages the potential social functions of research disciplines, and is guided by the concept of " expanding the emergency system of comprehensive emergency medicine". The authors identified the problems and shortcomings of the existing system and proposed to build a regional emergency medical system led by research disciplines. The path, system layout and functions are stated explicitly, while the system construction strategy is proposed by taking emergency treatment of myocardial infarction patients as an example. The system will be the pivotal support for integrating effectively regional emergency medical resources, improving the ability and level of emergency and first aid in medical institutions at various levels and of different types, promoting the formation of a new pattern of regional emergency medical service and achieving homogenized emergency medical services that everyone enjoy.
RESUMO
Under the situation of national demand for cardiopulmonary resuscitation (CPR) skills, it is very important to develop a scientific and feasible education and training program to popularize CPR skills, and improve first-aid ability. This study illustrated the significance and feasibility of setting up car-diopulmonary resuscitation courses in colleges and universities. On this basis, specific suggestions and countermeasures were put forward to improve teaching organization and leadership, teaching material de-velopment, curriculum design, teaching faculty development, teacher training and laboratory construction. This study proposed to strengthen the legislation, and the implementation of first-aid qualification examina-tion in colleges and universities, making the students become the preferred educational group of CPR skills, which is of great significance to improve public popularity rate of CPR.
RESUMO
Objective To preliminarily develop a scale to measure the proactive socialization behavior of new nurses and test validity and reliability of the scale, to explore the impact of proactive socialization behavior on turnover intention. Methods Using a questionnaire survey method to investigate 696 new nurses who had worked within three years in nursing organization, structural equation model and hierarchical line regression methods were performed to analyze the data. Results Proactive socialization behavior scale included eight items under one dimension;the consistency coefficient of scale was 0.858;new scale had a good convergent and predictive validity;the proactive socialization behavior of new nurses was significantly negative related to turnover intention (β=-0.236,P<0.01). Conclusions The proactive socialization behavior scale has a good reliability, convergent and predictive validity. Meanwhile, new nurses with higher level of proactive socialization behavior have lower turnover intention. Because they can quickly fit the new environment, role definition and organizational culture, which in turn organization embeddedness is promoted.
RESUMO
Objective To explore the effective procedures and practices to solve the ethical dilemma of nursing, and to building nursing ethics decision path. Methods Using inductive-deductive method, summarize predecessors′ research on nursing ethics mode and decision-making process, and establish nursing ethical decisions paths, then display the application based on clinical case. Results Six-steps-Nursing ethics decision path was established, and tested. Conclusions Pay attention to strengthen the cultivation of nurses nursing ethics accomplishment and ability of the decision.
RESUMO
BACKGROUND:Cholesterol is closely linked to the occurrence and progression of atherosclerosis. Current approaches to study celular cholesterol dynamics have their own limitations. OBJECTIVE: To measure the cholesterol efflux rate of RAW 264.7 mouse macrophages by BODIPY-Cholesterol labeling and to explore the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate. METHODS:RAW 264.7 cels were cultured in vitro with DMEM containing 10% fetal bovine serum, and labeled with BODIPY-Cholesterol for 1, 2, 4, 8 hours. Then, the cels were rinsed with serum-free DMEM and inoculated for 6, 12, 24, 48, 96 hours to optimize the labeling time and incubation time. We measured and compared the cholesterol efflux rates after cultured cels were treated with cholesterol, lipopolysaccharide, human sera with high cholesterol or human sera with normal cholesterol. RESULTS AND CONCLUSION: The best labeling time for BODIPY-Cholesterol was 2-8 hours. Cholesterol efflux rates were gradualy decreased after the cels that were labeled for 2 hours were incubated with increasing concentrations of cholesterol (0.1, 0.5, 2.5 mmol/L,P< 0.01). Treating cels with lipopolysaccharide also decreased the cholesterol efflux rate (P < 0.05). Furthermore, the cholesterol efflux rate was decreased after cels were treated with human sera with high cholesterol (P< 0.05). These findings indicate that BODIPY-Cholesterol can be used to measure celular cholesterol efflux rate and to study the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.
RESUMO
An in-depth analysis of the problems found in the hierarchical medical system,found that the research hospitals should focus on the conceptions of Big Times and Big Health,initiative the task to undertake Strong grass-roots,and actively build leading model of hierarchical medical system based on the PDCA cycle.At the same time,taking the practice of the 2nd Affiliated Hospital of Harbin Medical University as an example,we propose the research hospitals should strengthen service capabilities in primary health care institutions from talent,technology,management and other aspects, so as to enhance the patient's willingness to visit the grassroots,and to promote the further deepening of our medical reformation.
