Thinking of the cultivation mode of preventive medicine undergraduates based on student research training projects / 中华医学教育探索杂志

There are still some shortcomings in the training of preventive medicine undergraduates in China, such as outdated education mode, disjointed theory/practice, and lack of multi-dimensional integration. This paper proposes an attempt to reform the cultivation mode of preventive medicine undergraduates by combining student research training programs. However, many problems have been exposed during the implementation of the reform, and it has not achieved satisfactory results, especially in emergency management and solving practical problems. In order to cultivate practical preventive medicine talents in line with the needs of the times, the training mode based on student research training projects still needs considerable efforts in many aspects, including project approval, project guidance, project evaluation and so on.

Lecciones aprendidas y por aprender sobre la publicación científica estudiantil cubana / Lessons learned and to be learned about the Cuban student scientific publication

La evaluación ex ante es aquella que se efectúa antes de la realización de la intervención y busca conocer su pertinencia, viabilidad y eficacia potencial. Con el objetivo de describir las lecciones aprendidas y por aprender en torno a la publicación estudiantil se realizó un análisis documental de las investigaciones y publicaciones sobre la producción científica estudiantil en Cuba. Se identificaron 193 documentos en la base de datos SciELO, 457 documentos en Scopus y 75 en la WoS. Se identificaron 10 lecciones aprendidas y 5 por aprender en torno al tema. A través de la investigación y publicación en la etapa del pregrado, el estudiante aporta a su institución educativa como un científico más, a la par que rompe el equívoco dogma de que la universidad es únicamente para fines docentes. Existe potencial en las universidades cubanas para la investigación y publicación, la cual debe ser fomentada y apoyada por todas las autoridades competentes(AU)

The ex-ante evaluation is one that is carried out before the intervention is carried out and seeks to know its relevance, feasibility and potential effectiveness. With the aim of describing the lessons learned and to be learned about student publication, a documentary analysis of research and publications on student scientific production in Cuba was carried out. During the study period, 193 documents were identified in the SciELO database, 457 documents in Scopus and 75 in WoS. 10 lessons learned and 5 to be learned were identified on the subject. Through research and publication in the undergraduate stage, the student contributes to his educational institution as another scientist, while breaking the equivocal dogma that the university is only for teaching purposes. There is potential in Cuban universities for research and publication, which must be encouraged and supported by all competent authorities(AU)

Percepción del paciente sobre la aplicación de principios bioéticos en los cuidados de los estudiantes de enfermería / Patient's Perception of Bioethical Principles Application to Care by Nursing Students / Percepção do paciente sobre a aplicação de princípios bioéticos no cuidado de estudantes de enfermagem

Objetivo: Determinar a percepção que têm os pacientes do Hospital Instituto Ecuatoriano de Seguridad Social da cidade de Portoviejo sobre a aplicação de princípios bioéticos e cuidados oferecidos pelos alunos de enfermagem da Universidad Técnica de Manabí. Método: Trata-se de um estudo descritivo não experimental baseado na perspectiva qualitativo-quantitativa. Foi aplicado um inquérito a 36 pacientes do serviço de cirurgia do Hospital IESS Portoviejo que constituem a população total durante o período de outubro de 2016 a abril de 2017. O inquérito foi definido com base nos quatro princípios da bioética que são a autonomia, justiça, beneficência e não maleficência. Resultados: obtiveram-se como resultados mais relevantes que, com relação à autonomia, em média, a opção usual está acima de 70,00%; quanto ao princípio da justiça, obteve-se em média respostas que, na opção de habitual e de às vezes, distribuem-se 50,00% cada; por outro lado, em relação ao princípio da beneficência, os resultados obtidos refletem uma percepção positiva, sendo estes superiores a 75,00% na média; e por fim, sobre o princípio da não maleficência, os resultados obtidos refletem em média mais de 70,00% na opção de habitual, sendo este um fator positivo na percepção dos pacientes. Conclusões: os estudantes de enfermagem cumprem todos os aspectos envolvidos nos princípios da bioética durante o processo de atendimento no âmbito das práticas formativas

Objective: To determine the perception that the patients at the Hospital Instituto Ecuatoriano de Seguridad Social of the city of Portoviejo have about the application of bioethical principles and care by nursing students at the Universidad Técnica de Manabí. Method: Non-experimental descriptive, based on a qualitative-quantitative perspective, a survey was conducted among 36 surgery service patients at the Portoviejo IESS Hospital who make up the total population during the period from October 2016 to April 2017. The survey was defined based on the four principles of bioethics, which are autonomy, justice, beneficence, and non-maleficence. Results: The most relevant results were that, in terms of autonomy, the average option "always" is above 70.00%. Regarding the principle of justice, on average, it obtained answers in the options "always" and "sometimes" distributed 50.00% each. Regarding the principle of beneficence, the results obtained reflect a positive perception as they are, on average, higher than 75.00%. Finally, on the principle of non-maleficence, the results obtained reflect an average of more than 70.00% in the option "always", a positive factor in the patients' perception. Conclusions: Nursing students comply with all aspects involved in the principles of bioethics during the caring process within the framework of training practices

Conclusiones: los estudiantes de enfermería cumplen con todos los aspectos involucrados en los principios de la bioética durante el proceso de atención en el marco de las prácticas formativas.

Culture Conditions Optimization of Magnetotactic Bacteria WM-1 / 现代生物医学进展

The culture of Magnetospirillum magneticum WM-1 depends on several control factors that have great effect on the magnetic cells concentration. Investigation into the optimal culture conditions needs a large number of experiments. So it is desirable to minimize the number of experiments and maximize the information gained from them. The orthogonal design of experiments and mathematical statistical method are considered as effective methods to optimize the culture condition of magnetotactic bacteria WM-1 for high magnetic cells concentration. The effects of the four factors, such as pH value of medium, oxygen concentration of gas phase in the serum bottle, C:C (mtartaric acid: msuccinic acid) ratio and NaNO3 concentration, are simultaneously investigated by only sixteen experiments through the orthogonal design L16(44) method. The optimal culture condition is obtained. At the optimal culture condition (pH 7.0, a oxygen concentration 4.0%, C: C (mtartaric acid: msuccinic acid) ratio 1:2 and NaNO3 100 mg l-1), the magnetic cells concentration is promoted to 6.5×107 cells ml-1, approximately 8.3% higher than that under the initial conditions. The pH value of medium is very important factor for magnetic cells concentration. It can be proved that the orthogonal design of experiment is of 90% confidence. The results from the hysteresis of WM-1 shows that Hc = 230 Oe, Ms = 0.9 emu/g dry wt. Cells,and Mr / Ms = 0.50.
