Research progress on dental materials for preventing root caries / 口腔疾病防治

@#The high incidence and untreated rate of root caries, a common and frequently occurring oral disease with challenging treatment in elderly individuals, is the main cause of tooth loss among elderly people, as rapid development results in pulpitis and periapical periodontitis or residual crown and root, which has been regarded as one of the common chronic oral diseases seriously affecting the quality of life of elderly people. Thus, early intervention and prevention are important. Traditional dental materials for preventing root caries have been widely used in clinical practice; however, they have the disadvantages of tooth coloring, remineralization and low sterilization efficiency. A series of new dental materials for preventing root caries have gradually become a research hotspot recently, which have the advantages of promoting the mineralization of deep dental tissue, prolonging the action time and enhancing adhesion. Future caries prevention materials should be designed according to the characteristics of root surface caries and the application population and should be developed toward simplicity, high efficiency and low toxicity. This review describes current research regarding anti-caries prevention material application, serving as a theoretical underpinning for the research of root caries prevention materials, which is important for both promotion in the effective prevention of root caries and improvement in the status of oral health and the quality of life among old people.

Effect of different suspension moxibustion methods on syndrome characteristics of rats with rheumatoid arthritis of heat bi syndrome based on "moxibustion can be used for heat syndrome" / 中国针灸

OBJECTIVE@#To observe the effects of different suspension moxibustion methods on the syndrome characteristics and inflammatory factors of rats with rheumatoid arthritis (RA) of heat bi syndrome and to prove the concept of "moxibustion can be used for heat syndrome".@*METHODS@#Among seventy Wistar rats, 12 rats were randomly selected as a normal group, and the remaining rats were induced by collagen combined with wind, dampness, and heat environmental stimulation to establish the RA model of heat bi syndrome. Forty-eight rats with successful model establishment were further randomly divided into a model group and three moxibustion groups (mild moxibustion group, rotating moxibustion group and sparrow-pecking moxibustion group), with 12 rats in each group. The acupoints "Quchi" (LI 11), "Dazhui" (GV 14) and ashi point were used in all moxibustion groups, with mild moxibustion, rotating moxibustion, and sparrow-pecking moxibustion intervention given respectively, each acupoint was treated with moxibustion for 10 min a day, and 6 days were considered one course of treatment, with a total of three courses. After the intervention, the arthritis index (AI), the Evans blue (EB) extravasated volume in the soft tissue of the right hind paw, and the levels of tumor necrosis factor (TNF)-α and interleukin (IL)-10 in the serum were measured by ELISA in each group. The volume of the bilateral hind paw was measured; the infrared thermal imaging was collected to analyze the temperature of the plantar area of the bilateral foot pads, and the reaction time of plantar heat pain was calculated before and after modeling, as well as after the 1st, 2nd and 3rd courses of interrention. The ankle dorsiflexion angle of the right hind foot was also measured before and after modeling, as well as after the intervention.@*RESULTS@#After modeling, compared with the normal group, the rats in the model group had more high-temperature areas in the bilateral hind limbs, abnormal AI score, abnormal bilateral hind paw volume, abnormal temperature of the plantar area of the bilateral foot pads, abnormal foot pain response time, abnormal right hind ankle dorsiflexion angle, abnormal right hind paw soft tissue EB extravasation, and abnormal serum TNF-α and IL-10 levels (P<0.01, P<0.05). After the intervention, compared with the model group, the rats in each moxibustion group had decreased or disappeared high-temperature areas in the bilateral hind limbs, EB extravasated volume in the soft tissue of the right hind paw was reduced (P<0.05), and the right ankle dorsiflexion angle was increased (P<0.05), serum level of TNF-α was reduced, and level of IL-10 increased (P<0.05); the AI scores in the mild moxibustion group and the sparrow-pecking moxibustion group was decreased (P<0.01, P<0.05). After the 1st, 2nd and 3rd courses of intervention, compared with the model group, the bilateral hind paw volume of rats in each moxibustion group was decreased (P<0.05, P<0.01), and plantar heat pain reaction time was increased (P<0.05). After the 2nd course and the 3rd course of intervention, the temperature of the right hind paw pad area was decreased in each moribustion group (P<0.05); after the 3rd courses of intervention, the temperature of the left hind paw pad area was decreased in the mild moxibustion group (P<0.05).@*CONCLUSION@#Suspension moxibustion could adjust the serum levels of TNF-α and IL-10 to improve the syndrome characteristics of RA rats of heat bi syndrome, such as joint redness, swelling, heat, pain and activity restriction. The effect of mild moxibustion is the most prominent. The findings could provide scientific basis for "moxibustion can be used for heat syndrome".

Cognition of prevention and control of cervical cancer and influencing factors of HPV vaccination intention among college students in Xiangyang / 公共卫生与预防医学

Objective The knowledge of cervical cancer prevention and control，the cognition of human papillomavirus (HPV) vaccine and the willingness to vaccinate HPV vaccine among college students in Xiangyang were investigated and analyzed to provide a reliable scientific basis for the primary prevention of cervical cancer prevention and control in Xiangyang. Methods By means of stratified sampling method and self-made questionnaire, this paper conducted a questionnaire survey among college students in 3 universities in Xiangyang. Results A total of 8 523 college students participated in the questionnaire survey, and 4 473 of them had sufficient knowledge of cervical cancer prevention and control and HPV vaccine, with the awareness rate of 52.48%. Male students, rural residents and non-medical majors were the influencing factors of insufficient knowledge of cervical cancer prevention and control and HPV vaccine. Among the 6 459 female college students who participated in the survey, 5,993 (92.79%) were willing to be vaccinated, and 859 (13.30%) were already vaccinated. Major, educational background, living expenses and cognitive scores were the influencing factors of HPV vaccination intention. Conclusion College students in Xiangyang City are relatively deficient in the knowledge of cervical cancer prevention and control and HPV vaccine. Targetable science popularization and education can improve college students' correct understanding of cervical cancer prevention and control knowledge, promote the HPV vaccine vaccination plan, and reduce the occurrence of HPV-related diseases and cervical cancer.

Radiation dose estimation and protective measure discussion of 241Am-Be neutron source logging / 中国辐射卫生

Objective To investigate the radiation dose to operators in the process of 241Am-Be neutron source logging, and discuss neutron source management and protective measures for operators in well logging. Methods Through on-site observation and measurement of 241Am-Be neutron source logging in a company, we obtained the surface γ dose rate and neutron dose rate of the neutron source, as well as the operating time and distance of various processes including source taking, transfer, and loading, calculated the radiation dose to operators in various processes, and analyzed the source and proportion of the personal effective dose to operators. Results The effective doses of neutron irradiation and γ irradiation were 94.17 μSv and 2.72 μSv, respectively, for the combined processes of source tank inspection, transfer, and detection; 36.66 μSv and 24.08 μSv, respectively, for source loading and unloading; and 130.83 μSv and 26.80 μSv, respectively, for the whole neutron source logging process. The total annual effective dose of neutron source logging was 15.78 mSv, as estimated by logging 100 times per year. Conclusion In the process of 241Am-Be neutron source logging in the company, the effective dose to operators mainly arises from neutron irradiation. Therefore, it is necessary to strengthen neutron source management and take effective protective measures against neutron radiation.

Discovery and discussion of 7Be and another full-energy peak in water from 3D water phantom of a proton therapy system / 中国辐射卫生

Objective To discuss 7Be and a 77.2 keV full-energy peak with short half-life found in the water sample from the 3D water phantom of a proton therapy system. Methods We measured the water sample from the 3D water phantom of a proton therapy system according to Determination of Radionuclides in Water by Gamma Spectrometry (GB/T 16140—2018). Results The activity concentration of 7Be in the water sample was 1.30 × 101 Bq·L−1 on December 24, 2018; 4.3 × 101 Bq·L−1 on March 22, 2019; and 1.41 × 101 Bq·L−1 at the time of sampling on December 19, 2018. On December 24, 2018, the net peak area of the 77.2 keV full-energy peak in the sample was 683 ± 45, and the measurement time was 26123.02 s; on March 22, 2019, the net peak area decreased to the background level of 194 ± 49, and the measurement time was 86400.00 s. Conclusion In the 3D water phantom of the proton therapy system, 7Be can be generated from the spallation reaction between high-energy neutrons and oxygen in water. In addition, we find a full-energy peak at 77.2 keV with short half-life. The activity concentration of 7Be in the water sample is lower than the exemption level, but the activity concentration at sampling may not be the maximum activity concentration in the process of quality control. The inductive radionuclide 7Be produced in the 3D water phantom should be identified and properly evaluated in the assessment of occupational radiation hazards of proton therapy system.

Aportes del uso de Simuladores educativos en aula como una herramienta para mejorar la calidad del aprendizaje de los alumnos de la Facultad de Psicología de la UAQ / Contributions of the use of educational simulators in the classroom as a tool to improve the quality of learning in the students of the faculty of psychology of the UAQ

Dentro de este magnífico mundo de enseñanza ­aprendizaje existen muchos elementos de influencia más allá de solo un maestro, un alumno o un aula; crear ambientes de aprendizaje dinámicos, efectivos y orientados a la generación de aprendizaje significativo es tarea de todos los profesionales de la educación; para ello debemos romper esquemas, modelos anacrónicos y pensar en estrategias propositivas adaptadas a las nuevas y diferentes formas de aprender de las generaciones actuales y futuras creando entornos amigables, prácticos y efectivos. Este artículo plantea la utilización de simuladores en los ámbitos educativos, como una forma de facilitar el aprendizaje mediante el uso de los métodos y herramientas de transmisión de conocimiento adaptadas a las necesidades de aprendizaje actuales, es decir, de explotar las herramientas propias de la época en la que vivimos; en este caso las tecnológicas; esto se vuelve necesario considerando que tanto los métodos de enseñanza ­aprendizaje, como los sistemas educativos de hoy en día, ya no son del todo suficientes para cubrir las expectativas de educación actuales, debido a que hoy en día en muchos países aún se siguen utilizando métodos y estrategias educativas diseñadas para cubrir las necesidades de las sociedades del siglo pasado. En este documento se habla sobre la necesidad actual de contar con herramientas que potencialicen la calidad y efectividad del proceso de enseñanza ­aprendizaje en las aulas y de la propuesta de un método de investigación participativa en la cual es posible identificar cómo la implementación de herramientas TIC por medio del uso de simuladores en aula, es efectiva y benéfica para mejorarla adquisición y dominio de conocimiento en los estudiantes de la licenciatura de Psicología del trabajo de la Universidad Autónoma de Querétaro, logrando en ellos un mejor desempeño profesional y mayor éxito en las actividades propias de su profesión.

Around the magnific world of the teaching -learning, exist many influencing elements more than the only a professor, a student or an classroom; work to make a dynamic and effective learning environments and oriented to create significative learning is a job of all the professionals of learning, to do that, we have to broke schemes, anachronic models and think In propositives strategies aligned to the new and different ways of learn of the actually and future generations, creating friendly, practical and effective environments. This article proposes the use of simulator systems in educational environments, is a way to facilitate the learning through the use of methods and tools to help the transmission of knowledge adapted to current learning needs, that is to, exploit the modern tools; the technology tools. That becomes necessary considering that both the teaching ­learning methods and the actually educational systems, are very far from covering the current education expectations and needs because in many countries are using educational methods and strategies designed to comply the needs of the last century societies. This article, talk about the current need to count with tools that enhance the quality and effectiveness of the teaching -learning process in the classrooms and the proposal of a participatory investigation method with which is possible to identify how the implementation of TIC tools across the use of simulators in classroom is effective and beneficial to get better and acquire mastery of learning on the psychology students of autonomous university of Querétaro, achieving a better professional performance in them and greater success in professional activities.

The right to be forgotten and COVID-19: privacy versus public interest / El derecho al olvido y el COVID-19: privacidad frente a interés público / O direito ao esquecimento e COVID-19: privacidade versus interesse público

Abstract: Recent studies highlight the importance of digital surveillance to gather individual health information due to the global pandemic caused by the new COVID-19 disease. This paper analyses its legal and ethical implications at the interface between the individual right to privacy and the collective interests of public health. We framed the discussion in law, deontology and utilitarianism. The lasted theories and human rights, especially privacy, are crucial in our argument. Health-derived dilemmas and efforts to solve them, especially by information technologies, bioethics and law, exist at these perspectives' interface. In particular, we analysed the intersection between autonomy, the right to privacy, and the so-called 'right to be forgotten' in the public health context. In other words, we studied the right to obtain from the controller the erasure of health data - a radical means of control over personal data established in Article 17 of the General Data Protection Regulation (GDPR). Given the lack of specifics regarding collection and re-use of such data under the broad scope of public health purposes, implied consent does not address the issue of proportionality. We highlight legal safeguards' insufficiency, suggesting applying the 'right to be forgotten' according to an ethical interpretation.

Resumen: Estudios recientes destacan la importancia de la vigilancia digital para recoger información sanitaria individual debido a la pandemia mundial causada por la nueva enfermedad COVID-19. Este artículo analiza sus implicaciones legales y éticas en la interfaz entre el derecho individual a la privacidad y los intereses colectivos de la salud pública. Enmarcamos la discusión en el derecho, la deontología y el utilitarismo. Estas últimas teorías y los derechos humanos, especialmente la privacidad, son cruciales en nuestro argumento. Los dilemas relacionados con la salud y los esfuerzos por resolverlos, especialmente a través de la tecnología de la información, la bioética y el derecho, se encuentran en la interfaz de estas perspectivas. En particular, analizamos la intersección entre la autonomía, el derecho a la privacidad y el llamado "derecho al olvido" en el contexto de la salud pública. Es decir, estudiamos el derecho a obtener del responsable del tratamiento la supresión de los datos de salud, un medio radical de control sobre los datos personales establecido en el artículo 17 del Reglamento general de protección de datos (RGPD). Dada la falta de especificidades en cuanto a la recogida y reutilización de dichos datos dentro del amplio ámbito de los objetivos de salud pública, el consentimiento implícito no aborda la cuestión de la proporcionalidad. Destacamos la insuficiencia de las garantías legales, sugiriendo la aplicación del "derecho al olvido" según una interpretación ética.

Resumo: Estudos recentes salientam a importância da vigilância digital para recolher informações individuais de saúde devido à pandemia global causada pela nova doença COVID-19. Este artigo analisa as suas implicações legais e éticas na interface entre o direito individual à privacidade e os interesses coletivos da saúde pública. Enquadramos a discussão no direito, na deontologia e no utilitarismo. As últimas teorias e os direitos humanos, especialmente a privacidade, são cruciais na nossa argumentação. Dilemas derivados da saúde e esforços para os resolver, especialmente através das tecnologias da informação, da bioética e do direito, existem na interface destas perspetivas. Em particular, analisámos a intersecção entre autonomia, direito à privacidade, e o chamado "direito ao esquecimento" no contexto da saúde pública. Por outras palavras, estudámos o direito de obter do responsável pelo tratamento o apagamento dos dados de saúde, um meio radical de controlo dos dados pessoais estabelecido no artigo 17º do Regulamento Geral de Proteção de Dados (RGPD). Dada a falta de especificidades em relação à recolha e reutilização de tais dados no âmbito alargado dos objetivos de saúde pública, o consentimento implícito não aborda a questão da proporcionalidade. Destacamos a insuficiência de salvaguardas jurídicas, sugerindo a aplicação do "direito ao esquecimento" de acordo com uma interpretação ética.

The right to be forgotten versus the right to disclosure of gamete donors' id: ethical and legal considerations / El derecho al olvido frente al derecho a revelar la identificación de los donantes de gametos: consideraciones éticas y jurídicas / O direito ao esquecimento versus o direito à divulgação da identificação de dadores de gâmetas: considerações éticas e legais

Abstract: 15. The anonymity of gamete donors in the context of medically-assisted reproduction techniques (ART) and the right of the offspring to know their genetic or biological parents' identity is a controversial and widely debated topic in the scientific literature. The positions on the issue in each country are different. Sometimes they are in opposition to each other even in countries with strong similarities, such as those in the European Union (EU), in the framework of shared ethical values. Although some countries still enshrine the rule of anonymity, there is an undeniable tendency to guarantee the right to know one's origins by creating relevant exceptions or abolishing donor anonymity status altogether. 16. This article offers ethical and legal considerations of whether the so-called 'right to be forgotten' (RTBF) could be extended to include gamete donors' right to remain anonymous. This perspective goes against the general trend, certainly in Europe, of recognizing that offspring born from donor gametes have a right to access information relating to their genetic progenitors. The novel addition is to question whether the General Data Protection Regulation (GDPR) might provide fertile ground for questioning this approach, and effectively support those jurisdictions where anonymity is still possible.

Resumen: 20. El anonimato de los donantes de gametos en el contexto de las técnicas de reproducción médicamente asistida (RM) y el derecho de la descendencia a conocer su identidad genética o biológica es un tema controvertido y ampliamente debatido en la literatura científica. Las posiciones sobre el tema en cada país son diferentes. A veces se oponen entre sí, incluso en países con fuertes similitudes, como los de la Unión Europea (UE), en el marco de valores éticos compartidos. Aunque algunos países siguen consagrando la norma del anonimato, es innegable la tendencia a garantizar el derecho a conocer el propio origen creando las excepciones pertinentes o suprimiendo por completo el estatus de anonimato del donante. 21. Este artículo ofrece consideraciones éticas y jurídicas sobre si el llamado "derecho al olvido" podría ampliarse para incluir el derecho de los donantes de gametos a permanecer en el anonimato. Esta opinión es contraria a la tendencia general, ciertamente en Europa, de reconocer que los hijos nacidos de gametos donados tienen derecho a acceder a la información relativa a sus padres genéticos. La nueva adición consiste en debatir si el Reglamento general de protección de datos (RGPD) podría proporcionar un terreno fértil para cuestionar este enfoque y apoyar efectivamente a las jurisdicciones en las que el anonimato sigue siendo posible.

Resumo 25. O anonimato dos dadores de gâmetas no contexto das técnicas de reprodução medicamente assistida (RMA) e o direito da descendência a conhecer a sua identidade genética ou biológica é um tema controverso e amplamente debatido na literatura científica. As posições sobre a questão em cada país são diferentes. Por vezes estão em oposição umas às outras, mesmo em países com fortes semelhanças, como os da União Europeia (UE), no quadro de valores éticos partilhados. Embora alguns países ainda consagrem a regra do anonimato, existe uma tendência inegável para garantir o direito de conhecer as suas origens, criando exceções relevantes ou abolindo completamente o estatuto de anonimato dos dadores. 26. Este artigo oferece considerações éticas e legais sobre se o chamado "direito ao esquecimento" poderia ser alargado para incluir o direito dos dadores de gâmetas a permanecerem anónimos. Esta perspetiva vai contra a tendência geral, certamente na Europa, de reconhecer que os descendentes nascidos de gâmetas doadas têm o direito de aceder à informação relacionada com os seus progenitores genéticos. O novo aditamento é debater se o Regulamento Geral de Proteção de Dados (RGPD) poderá fornecer um terreno fértil para questionar esta abordagem, e apoiar efetivamente as jurisdições onde o anonimato ainda é possível.

Reflexos da (in)capacidade de estar só em tempos de isolamento social na pandemia COVID-19 / Reflections of the (in)ability to be alone in times of social isolation in pandemia COVID-19

As medidas adotadas em diversos países, necessárias como tentativa de contenção da pandemia causada pelo novo coronavírus (COVID-19), desencadearam mudanças radicais no dia a dia dos indivíduos, ocasionando sentimentos de incerteza, angústia, ansiedade e depressão na população em geral. O aumento do sentimento de solidão levou muitos indivíduos a utilizarem recursos internos e pôs à prova a capacidade de estar só. Alguns conceitos psicanalíticos evidenciam que o indivíduo que atinge um ego integrado, através de cuidados maternos suficientemente bons nos momentos primitivos, como bebê, adquire a capacidade de estar só. Isso ressalta a importância das primeiras relações objetais para a construção de um mundo interno satisfatório. Em contrapartida, a interrupção desse amadurecimento emocional pode despertar no sujeito adulto a utilização de mecanismos de ordem externa, como diversos tipos de adições, exposição a comportamentos de risco e, provavelmente, no caso da pandemia, desrespeito às medidas de distanciamento social. Diante disso, observa-se quão importante é o desenvolvimento saudável das primeiras relações objetais para que o indivíduo seja capaz de lidar com a solidão, e adote estratégias saudáveis ao longo da vida, inclusive em situações críticas. Assim, esse artigo se propõe a revisar alguns aspectos da teoria psicanalítica sobre a capacidade de estar só dentro do desenvolvimento emocional e compreender as consequências psíquicas resultantes das falhas nessa etapa da vida psíquica dos indivíduos.(AU)

The measures adopted in several countries, necessary as an attempt to contain the pandemic caused by the new coronavirus (COVID 19), triggered radical changes in the daily lives of individuals, causing feelings of uncertainty, anguish, anxiety and depression in the general population. The increased feeling of loneliness has led many individuals to use internal resources and test their ability to be alone. Some psychoanalytic concepts show that the individual who reaches an integrated ego, through maternal care good enough in primitive moments, as a baby, acquires the ability to be alone. This underscores the importance of early object relations for building a satisfying inner world. On the other hand, the interruption of this emotional maturation can awaken in the adult the use of external mechanisms, such as various types of addictions, exposure to risky behaviors and probably, in the case of the pandemic, disrespect to the measures of social distancing. Therefore, it is observed how important the healthy development of the first object relations is for the individual to be able to deal with loneliness, and to adopt healthy strategies throughout life, including in critical situations. Thus, this article set out to review some aspects of psychoanalytic theory about the ability to be alone within emotional development and to understand the psychic consequences resulting from failures in this stage of the psychic life of individuals.(AU)

Las medidas adoptadas en varios países, necesarias como intento de contener la pandemia por el nuevo coronavirus (COVID 19), desencadenaron cambios radicales en la vida cotidiana de las personas, causando sentimientos de incertidumbre, angustia, ansiedad y depresión en la población en general. El aumento de la sensación de soledad ha llevado a muchas personas a utilizar recursos internos y ha puesto a prueba la capacidad de estar solos. Algunos conceptos psicoanalíticos muestran que el individuo que alcanza un ego integrado, a través del cuidado materno suficientemente bueno en momentos primitivos, como un bebé, adquiere la capacidad de estar solo. Esto resalta la importancia de las primeras relaciones de objeto para la construcción de un mundo interno satisfactorio. Por otro lado, la interrupción de esta maduración emocional puede despertar en el sujeto adulto el uso de mecanismos externos, como varios tipos de adicciones, la exposición a conductas de riesgo y probablemente, en el caso de la pandemia, la falta de respeto a las medidas de distanciamiento social. Por lo tanto, se observa cuán importante es el sano desarrollo de las primeras relaciones de objeto para que el individuo sea capaz de afrontar la soledad y adoptar estrategias saludables a lo largo de la vida, incluso en situaciones críticas. Así, este artículo se propuso revisar algunos aspectos de la teoría psicoanalítica sobre la capacidad de estar solo dentro del desarrollo emocional y comprender las consecuencias psíquicas derivadas de los fracasos en esta etapa de la vida psíquica de los individuos.(AU)

Este trabajo consiste en comparar el concepto de sujeto propuesto por Jacques Lacan al psicoanálisis con la concepción de subjetividad que puede deducirse de la obra de Jean-Paul Sartre que da lugar a su propuesta de un psicoanálisis existencial

This work consists of comparing the concept of subject proposed by Jacques Lacan to psychoanalysis with the conception of subjectivity that can be deduced from the work of Jean-Paul Sartre that gives rise to his proposal of an existential psychoanalysis

Experiencia de aplicación de modelos de seguimiento de cumplimiento del perfil de egreso en el plan de estudios en las carreras de la Facultad de Medicina de la Universidad Finis Terrae / Experience of applying models for monitoring compliance with the graduation profile in the study plan in the careers of the Faculty of Medicine of the Finis Terrae University

El Perfil de egreso constituye un modelo teórico y la imagen del profesional que la institución de educación superior aspira formar. Es un conjunto de atributos que son certificados y le permiten a una persona ser reconocida y aceptada por la sociedad como profesional. La emergencia de estándares de calidad, utilizados por las agencias de acreditación de carreras universitarias, hoy exigen la necesidad de evaluar y rendir cuentas acerca del logro de las competencias establecidas y declaradas en el perfil de egreso, sin embargo, hay escasa evidencia concreta que demuestre modelos operativos de cómo abordar ese proceso de evaluación en distintos programas. Dada la relevancia del Perfil de Egreso de una carrera de pregrado y considerando que constituye el eje fundamental para el desarrollo curricular de los programas educativos, para realizar el proceso de autoevaluación y la posterior acreditación de las carreras, diseñamos e implementamos un modelo de seguimiento del cumplimiento del perfil de egreso en el plan de estudios de las carreras de la Facultad de Medicina de la Universidad Finis Terrae.

The Graduate Profile constitutes the theoretical model and the professional image that higher education aspires to form. It is a set of certified attributes and allows a person to be recognized and accepted by society as a professional. The emergence of quality standards, used by university careers' accreditation agencies, demands the need to evaluate and be accountable for achieving the competencies established and declared in the Graduate Profile. However, the is limited concrete evidence to demonstrate operational models of how to approach this evaluation process in different programs. Given the relevance of the Graduate Profile of an undergraduate career and considering that it constitutes the fundamental axis for the curricular development of educational programs, to carry out the self-evaluation process and the subsequent accreditation of the degrees, we design and implement a model for monitoring the compliance with the graduation profile in the study plan of the Faculty of Medicine of Universidad Finis Terrae.

Monitoring and analysis of activity concentrations of 7Be and 210Pb in atmospheric aerosol in Beijing from 2017 to 2020 / 中华放射医学与防护杂志

Objective:To monitor and analyze the activity concentrations of 7Be and 210Pb in atmospheric aerosol in Beijing from 2017 to 2020. Methods:Totally 1 074 atmospheric aerosol samples were collected by high flow air sampler (SnowWhite) including 275 in spring, 266 in summer, 262 in autumn and 271 in winter and subjected to analysis by low background high-purity germanium gamma-ray spectrometery (ORTEC) to determine the activity concentrations of 7Be and 210Pb. Results:The activity concentrations of 7Be in atmospheric aerosol were from 0.56 to 14.84 mBq/m 3, with an avearage of 6.84 mBq/m 3, and from 0.01 to 9.37 mBq/m 3 for 210Pb, with an avearage 3.19 mBq/m 3. The differences in activity concentrations of 7Be and 210Pb in atmospheric aerosol among differernt seasons were statistically significant ( F=32.66, 93.93, P<0.05). Activity concentration of 7Be was highest in spring, followed by autumn, and lowest in summer and winter. Activity concentration of 210Pb ranged from winter, autumn, spring to summer in descending order. Conclusions:The activity concentrations of 7Be and 210Pb in atmospheric aerosol in Beijing from 2017 to 2020 fluctated within the range of normal level.

Electroacupuncture Inhibits Neuronal Apoptosis Induced by Bilirubin Encephalopathy in SD Suckling Rats by Regulating NGB and PI3K/Akt Signaling Pathways / 中国生物化学与分子生物学报

Objective In this study, electroacupuncture (EA) was used to analyze the expression changes of related proteins in neuroglobin (NGB), PI3K/AKT and apoptotic pathways in the temporal cortex of bilirubin encephalopathy (BE) rats, so as to investigate the therapeutic effect of EA on BE and the relevant mechanism of NGB in this process. Totally 39 seven-day-old SD rats were divided into Sham, BE model and BE+EA groups. The neonatal BE model was established by injecting bilirubin solution (10 μg UCB/g Weight) into the cerebellomedullary cistern, Sham group was injected with the same amount of normal saline. BE rats were treated with EA at Baihui (GV20) and Quchi (LI11) acupoints with the frequency of 2/15 Hz for 15 min. Treatment was performed 12 h before modeling, followed by treatment every 12 h, in a total of three times. HE, Nissl staining and electron microscopy (TEM) were used to observe the pathological and ultrastructural changes of nerve cells in each group. Results showed that EA treatment reduced the damage of cortical neurons of BE rats and increase the number of Nissl bodies. TEM confirmed that EA treatment could alleviate the degree of mitochondria edema. Immunofluorescence staining was used to detect the expression sites and cell types of NGB. Results showed that NGB was mainly expressed in cortical neurons. Western blotting showed that EA treatment increased the expression of NGB, PI3K (p110 alpha), pAKT (Ser473) (P< 0. 05, P< 0. 05 and P< 0. 01, respectively) and the ratio of apoptosis-related protein Bcl-2/Bax (P < 0. 001), decreased the expression of Cleaved Caspase-3 (P< 0. 05) in the temporal cortex of rats. TUNEL staining showed that EA reduced the number of apoptotic cells (BE group 186. 00±13. 86 vs BE+EA group 78. 67±11. 85, P< 0. 01) . This study confirms that EA can promote the expression of NGB in the temporal cortex of BE rats, then activate the PI3K/AKT pathway to exert its neuroprotective function and inhibit the occurrence of apoptosis. EA may become a potential treatment method for BE.
