Construction of Knowledge Graph Based on Literature Data by Taking Treatment of Diabetic Peripheral Neuropathy with Traditional Chinese Medicine as An Example / 中国实验方剂学杂志

ObjectiveTo systematically sort out the knowledge framework and conceptual logic relationship of "disease-syndrome-treatment-prescription-medicine" in the existing literature on traditional Chinese medicine（TCM） treatment of diabetic peripheral neuropathy（DPN）， to construct of the knowledge map of TCM treatment of DPN， and to promote the explicitation of the implicit knowledge in the literature on the treatment of DPN with TCM. MethodTaking the literature of China National Knowledge Infrastructure about TCM treatment of DPN as the main data source， TCM-related concepts and entities were constructed by manual citation， and the corresponding relationships between the entities were established. Structured data were formed by processing with Python 3.7， and the knowledge graph was constructed based on Neo4j 3.5.34 graph database. ResultThe resulting knowledge graph with TCM diagnosis and treatment logic， defined 12 node labels such as prescriptions， Chinese medicines and syndrome types at the schema layer， as well as 4 types of relationships， such as inclusion， correspondence， selection and composition. It could support the query and discovery of nodes（syndrome elements， syndrome types and treatment methods）， as well as the relationship between each node. ConclusionBased on the literature data， this study constructed a knowledge map for TCM treatment of DPN， which brought together various methods of TCM treatment of DPN， including internal and external treatment. The whole chain knowledge structure of syndrome differentiation and classification for DPN treatment is formed from syndrome element analysis， syndrome type composition to treatment method selection， which can provide new ideas and methods for literature data to serve clinical and scientific research work， as well as reference for visualization of TCM literature knowledge， intellectualization of TCM knowledge services and the standardization of TCM diagnosis and treatment.

Textual Research on Principle of Dose Conversion in Ancient Famous Classical Formulas / 中国实验方剂学杂志

Due to the difference between the system of weights and measures， and the dosage of clinical prescriptions of traditional Chinese medicine in various historical periods， the dosage and conversion standard of prescriptions in past dynasties are different. Therefore， when discounting the dosage of famous classical formulas， the principles of inheriting the essence， making the past serve the present， linking the past and the present， and forming a consensus should be followed， firstly， the dosage of the prescription was converted according to the weights and measures system of the past dynasties. If the converted dosage significantly exceeds the provisions of the 2020 edition of Chinese Pharmacopoeia， then on the premise of ensuring that the proportion of the original prescription drug dosage remains unchanged， the conversion shall be based on expert consensus and drug safety evaluation. For drugs measured in non-standard units， a conversion range is provided based on comprehensive literature analysis and physical measurements. For the conversion of service volume， the original text was used as the basis for the conversion with reference to the measurement standards of different eras. If the original dosage is not clear， the converted dosage will be determined based on the historical evolution of the formula， referring to relevant ancient books， and combining modern applications. Eventually， the converting standard for famous classical formulas was determined as follows：during the Han and Tang dynasties， one Liang（两） was equivalent to 13.8 g and one Sheng（升） was equivalent to 200 mL， in the Tang dynasty， one Fen（分） was equivalent to 3.45 g， during the Song， Jin and Yuan dynasties， one Qian（钱） was equivalent to 4.13 g and one Zhan（盏） was equivalent to 300 mL， during the Ming and Qing dynasties， one Qian（钱） was equivalent to 3.73 g， and one Bei（杯） and one Zhong（盅） were equivalent to 200 mL. For drugs recorded in non-standard units of measurement， it is necessary to conduct actual measurements to determine their conversion standards based on comprehensive analysis to determine their origin. If necessary， different records of the dosage of drugs with the same or similar efficacy and indications in medical books of similar ages can be used to assist in determining the conversion standards. The analysis of the principle of dosage conversion for Chinese medicine is helpful for the clinical application and development of famous classical formulas.

Science and Technology Ethics Governance, How to Put Ethics First? / 中国医学伦理学

Science and technology ethics governance, how to put ethics first? The purpose of "technological innovation, ethics first" is to build an ethical soft landing mechanism for scientific and technological innovation. Researchers of science and technology ethics should start from the practice of international and domestic science and technology ethics governance, and explore the realistic way of science and technology ethics governance on the basis of understanding and thinking about the innovative culture, value orientation and operation mechanism. First of all, it should be noted that seeking technical, management and institutional solutions in the current ethical governance of science and technology may not be perfect and thorough, but operable management measures can be explored and continuously improved under the framework of mainstream scientific and technological innovation. Secondly, the co-governance of science and technology ethics needs to further explore the corresponding group co-governance epistemology facing pluralistic co-governance. Finally, the ethical governance of science and technology should pay attention to the principle of proportionality, and avoid both lax and being too strict.

Discussion on the Continued Use of Assisted Reproductive Technology for Widowed Single Women / 中国医学伦理学

Assisted Reproductive Technology(ART) as a medical technology to treat infertility is gradually increasing the applications in domestic and foreign countries. In fact, some single women have birth demands for the application of ART in China. This paper described the reasons why some single women in China have demands for the application of ART, and analyzed the relevant legal, ethical and social issues that may be faced in the applying of technologies. Besides, the paper suggested that the using of ART in single women should be banned in principle, but for some widowed single women who lost their husbands during the process of ART, considering allowing them to complete the unfinished applications at their request. Meanwhile, a self-assessment mechanism should be established for these widowed single women, and ethical principles and managements should be strictly followed in the process of ART application to prevent the abuse of technology and fully protect the interests of offspring.

Percepciones sobre la aplicación de principios bioéticos en mujeres puérperas en un Hospital público del Ecuador

Fundamento: El puerperio es el periodo de tiempo que comienza en la finalización del parto hasta las seis semanas posparto; durante el cual, es necesario brindar atención conforme a los principios bioéticos inscritos en la normativa de salud vigente en el Ecuador. Objetivo: Analizar las percepciones que tienen las mujeres puérperas sobre la aplicación de los 4 principios bioéticos durante la atención en salud. Metodología: El estudio es de tipo descriptivo con enfoque cualitativo. Los datos corresponden a 10 mujeres puérperas mayores de edad, atendidas en el Hospital Gineco Obstétrico Pediátrico de Nueva Aurora "Luz Elena Arizmendi" de la ciudad de Quito, que respondieron a una entrevista sobre los principios bioéticos aplicados en la atención recibida. Se realizaron análisis de contenido a través del software ATLAS TI versión 23. Resultados: Se obtuvo una percepción positiva de las mujeres puérperas acerca de la aplicación del principio de justicia. Por otra parte, se evidencian dificultades en el de autonomía, sobre todo en la comprensión de la información brindada a la paciente acerca de los procedimientos durante el parto y puerperio, además de coacciones por parte del personal sanitario. Se percibe el consentimiento informado como un mero trámite administrativo. El principio de beneficencia se lo asume como parte de la vocación del personal y la no maleficencia genera malestar si no va acompañado de información clara y oportuna. Conclusiones: Los principios bioéticos son transversales en la normativa de salud vigente, pero sobresale el de justicia en la atención a mujeres puérperas.

Background: The puerperium is the period of time beginning at the end of labor until six postpartum weeks; during which it is necessary to provide attention in accordance with the bioethical principles included in the current health guidelines in Ecuador. Objective: To analyze the perceptions that postpartum women have about the 4 bioethical principles application during health care. Methodology: The study type is descriptive with a qualitative approach. The data correspond to 10 adult postpartum women assisted at the Nueva Aurora "Luz Elena Arizmendi" Pediatric Obstetric and Gynecological Pediatric Hospital in the Quito city, who responded to an interview about the bioethical principles applied in the received care. Content analysis was conducted through ATLAS TI version 23 software. Results: A positive perception was obtained from postpartum women concerning the application of the Justice principle. Furthermore, difficulties are evident in the Autonomy section, mainly in the comprehension of the information provided to the patient about the procedures during the labor and puerperium, as well as coercion by health personnel. Informed consent is perceived as a mere administrative formality. The Beneficence principle is assumed as part of the vocation of the personnel and Non-maleficence generates discomfort if it is not accompanied by clear and opportune information. Conclusions: Bioethical principles are transversal in current health guidelines, but that of Justice stands out in the care of postpartum women.

Considerações ético-legais sobre a sedação paliativa: a discussão que a pandemia trouxe à tona no norte do Brasil / Ethical and legal considerations for palliative sedation: the debate sparked by the pandemic in northern Brazil / Consideraciones ético-legales sobre la sedación paliativa: la discusión que la pandemia trajo a la luz en el norte de Brasil

Objetivo: analisar o cabimento ético-legal da sedação paliativa, distinguindo-a de condutas que possam ser consideradas eutanásicas e, portanto, penalmente vedadas pelo ordenamento jurídico pátrio e tradicionalmente rechaçadas pelos Códigos de Ética profissionais. Metodologia: mediante pesquisa exploratória bibliográfica, a partir de obras doutrinárias especializadas no tema dos conceitos associados a fim de vida e da disciplina normativa vigente, o estudo buscou cotejar o uso da sedação paliativa com outras condutas e situações relacionadas a terminalidade e morte, de sorte a procurar identificar com maior clareza a qualificação ética e jurídica da prática, sua relevância e licitude no campo dos cuidados paliativos. Resultados: verificou-se que, em meio à crise pandêmica, situações de mistanásia por carência de recursos nas unidades de saúde do estado do Amazonas levaram a uma indevida confusão na compreensão social entre sedação paliativa e eutanásia, impondo-se a necessidade de esclarecer os conceitos e limites entre as condutas. Conclusão: constatou-se a possibilidade jurídica de sedação paliativa como conduta ética e legal, desde que exercida dentro das exigências da boa prática clínica, sem intenção de deliberado encurtamento vital.

Objective: to examine the ethical-legal significance of palliative sedation and to distinguish it from acts that can be described as euthanasia and are therefore prohibited by law in the national legal system and generally rejected by professional ethical Codes. Methods:an exploratory literature review based on textbooks on end-of-life concepts and current normative discipline was conducted to further determine the ethical and legal qualifications of the practice, its relevance and legality in the field of palliative care. Results: The findings revealed that, during the pandemic crisis, misthanasia due to lack of resources in health facilities in the state of Amazonas has led to an undue confusion in social understanding of palliative sedation and euthanasia, so that clarification of the concepts and boundaries between conducts is necessary. Conclusion: the legality of palliative sedation has been confirmed as an ethical and legal behavior, provided it is used within the parameters of good clinical practice and without the intention of deliberately shortening life.

Objetivo: evaluar las implicaciones éticas y legales de la sedación paliativa, diferenciándola de acciones que podrían ser consideradas eutanásicas y, por lo tanto, prohibidas por la ley nacional y tradicionalmente rechazadas por los Códigos de Ética profesional. Metodología: a través de una investigación bibliográfica exploratoria, basada en trabajos doctrinales especializados en el tema de los conceptos asociados al final de la vida y la disciplina normativa actual, el estudio buscó comparar el uso de la sedación paliativa con otras conductas y situaciones relacionadas con la terminalidad y la muerte, con el fin de buscar identificar más claramente la calificación ético-legal de la práctica, su pertinencia y legalidad en el campo de los cuidados paliativos. Resultados: durante la crisis pandémica, las situaciones de mistanasia en las unidades de salud del estado de Amazonas debido a la falta de recursos causaron una confusión indebida en el entendimiento social entre la sedación paliativa y la eutanasia , imponiendo la necesidad de esclarecer los conceptos y límites entre conductas. Conclusión: la sedación paliativa es legal y ética si se realiza dentro de las normas de la buena práctica clínica y sin la intención de reducir deliberadamente la vida.

Estudio transversal en profesionales de la salud sobre aplicación y percepción de conocimientos bioéticos adquiridos en urgencias pediátricas / Estudio transversal en profesionales de la salud sobre aplicación y percepción de conocimientos bioéticos adquiridos en urgencias pediátricas

Introducción En comparación con ciencias clínicas básicas o aplicadas, la bioética es considerada una disciplina secundaria y subutilizada en la práctica diaria. Sin embargo, el razonamiento ético es indispensable para la calidad del cuidado. Existen pocos estudios sobre bioética en unidades de emergencia pediátrica. Nuestro objetivo fue evaluar la percepción sobre la importancia y la suficiencia del conocimiento teórico adquirido y la aplicación de los principios bioéticos en casos estandarizados. Métodos Realizamos un estudio descriptivo transversal en profesionales médicos y de enfermería que se desempeñan en unidades de emergencia pediátrica de Puerto Montt. Mediante una encuesta, evaluamos la percepción de la importancia y suficiencia del conocimiento bioético obtenido y la aplicación de los principios bioéticos en casos hipotéticos, pero probables, en la atención de urgencias pediátricas. Resultados De una población total de 50 médicos y 53 enfermeras, participaron en nuestro estudio 30 médicos (60%) y 20 enfermeras (37,7%). La mayoría reportó formación ética en pregrado (84%). Una minoría reportó formación durante la práctica (20%). Sin embargo, sólo 60% percibía tener conocimientos suficientes de bioética y 72% la consideraba importante para la práctica diaria. Además, al aplicar los principios de Beauchamp y Childress a casos clínicos estandarizados, el 82,7% no reconoció el principio de justicia y solo 50% reconoció los principios de autonomía y no maleficencia. Conclusión Aunque la mayoría de los profesionales de la salud tienen formación en bioética, el aprendizaje muchas veces se considera insuficiente y no se incorpora a la práctica diaria en las unidades de emergencia pediátrica.

Background Compared to basic or applied clinical sciences, bioethics is frequently considered as a secondary discipline and underutilized in daily practice. However, ethical reasoning is indispensable for the quality of care. There are few studies on bioethics in pediatric emergency units. Our objective was to evaluate the perception of the acquired bioethical knowledge and the application of bioethical principles in standardized cases. Methods We conducted a cross-sectional descriptive study in medical and nursing professionals working at pediatric emergency units in Puerto Montt. Through a survey, we assessed the perception of the sufficiency of the acquired bioethics knowledge and the application of bioethical principles on hypothetical, but probable cases in emergency pediatric care. Results Of a total population of 50 physicians and 53 nurses, 30 physicians (60.0%) and 20 nurses (38.7%) participated in our study. The majority reported ethics training in undergraduate education: 84%. A minority reported training during practice: 20%. However, only 60.0% perceived having sufficient knowledge of bioethics and 72.0% considered it important for daily practice. Further, when applying the principles of Beauchamp and Childress to standardized clinical cases, 82.7% did not recognize the justice principle and only 50.00% the principles of autonomy and nonmaleficence. Conclusion Although most health professionals undergo bioethics training, learning is often considered insufficient and not incorporated into daily practice at pediatric emergency units.

Controversias éticas en la atención del aborto, fertilización in vitro y anticoncepción en la mujer

En relación con los procesos de reproducción, las evidencias científicas de los últimos años y la vasta y mejor información con la que se cuenta para medir y estimar los indicadores de morbilidad y mortalidad en salud reproductiva han llevado a definir nuevas estrategias en el marco del derecho a la salud que tienen las mujeres. Para algunas personas son planteamientos claros, pero para otros no tanto, generando a la luz de los principios de ética controversias que es necesario plantear y, si es posible, resolver. En ese sentido, se ha seleccionado para esta presentación el aborto, la reproducción asistida y la anticoncepción, temas actuales que suscitan opiniones diferentes o contrapuestas de personas o instituciones, no siempre producto de una reflexión, justa, honrada, no ideologizada, buscando el bienestar de las personas. A veces, es el resultado de la satisfacción de un interés personal o institucional.

In relation to reproductive processes, the scientific evidence of recent years and the vast and better information available for measuring and estimating morbidity and mortality indicators in reproductive health have led to the definition of new strategies within the framework of women's right to health. For some people these approaches are clear, but for others they are not so clear, generating controversies in the light of ethical principles that need to be raised and, if possible, resolved. In this sense, we have selected for this presentation abortion, assisted reproduction and contraception, current issues that raise different or opposing opinions of individuals or institutions, not always the product of a reflection, fair, honest, non-ideologized, looking for the welfare of people. Sometimes, it is the result of the satisfaction of a personal or institutional interest.

Confessions of an Ayurveda professor

In this essay, I narrate my experiences of teaching Ayurveda physiology through an approach that involved laborious re-interpretation of ancient literature using the recent advances in the field of medical physiology. Though this approach made the ancient concepts and theories appear modern and relevant, it did not contribute much except for apparently reducing cognitive dissonance among students. I cite examples describing the processes of formation of shukra (semen) and rakta (blood) to show how we often overinterpret Ayurveda concepts to make them sound rational by proposing ad hoc conjectures. I illustrate why my previous writings were faulty by applying the falsification principle proposed by Karl Popper. I further explain how this approach made these concepts only verifiable but not refutable, and hence, non-falsifiable. I argue that instead of using such re-interpretation to prove obsolete concepts, they can be dropped altogether from the curricula of Ayurveda programmes. There is a need to develop a reliable method to identify such outdated content.

Considerations on investigation on quality standard of Chinese patent medicine / 药学学报

Chinese patent medicine (CPM) is an important part of traditional and Chinese medicine (TCM). Its quality has direct impact on the safety and effectiveness of clinical use. The quality standard is the pivotal approach to guarantee the quality of CPM. Due to the complex material basis, multitudinous quality influencing factors and unveiled active ingredients, dose-effect relationship and action mechanism, the investigation on quality standard faces many difficulties. This paper surveys the current quality status of CPM and the general situation of CPM standards. At present, the dosing problem has the crucial impact on the quality of CPM. The current quality standard system of CPM is confirmed and the limitations are indicated. Based on the above analysis, the principles and considerations on investigation of quality standard are proposed as follows: ① Adhere to safety as the bottom line, strengthen the risk-control ability of the standard of CPM; ② Adhere to theory of TCM and comprehensive quality, improve the integrative control level of the CPM standard; ③ Emphasize technological development and innovation, promote the quality control competence of CPM standard; ④ Facilitate planning and coordination, optimize the management of the CPM standard system; ⑤ Reinforce investigation on evaluation method, develop grade evaluation standard, accelerate high-quality development of CPM. Finally, the future perspective on investigation of CPM quality standard is prospected.

Validez de la unidad nacional en el pensamiento de Fidel Castro para enfrentar la COVID-19 / Validity of national unity in the thought of Fidel Castro to face COVID-19

En el ideario de Fidel Castro se aprecian sus consideraciones acerca de la necesidad de la unidad para vencer cualquier obstáculo que pretenda detener el curso de la Revolución cubana, en lo fundamental dirigidas hacia las maniobras desestabilizadoras de los enemigos de la patria; sin embargo, esa convicción fidelista de que la unidad garantiza el triunfo está presente en la batalla que se ha librado, y aún se libra, contra la COVID-19, donde el pueblo, organizado en diversos sectores, continúa obteniendo resultados positivos en contra de esta pandemia. Es objetivo de estos autores compartir algunas de sus ideas que servirán de análisis e inspiración para su aplicación en el actual contexto epidemiológico.

In Fidel Castro's ideology, his considerations about the need for unity to overcome any obstacle that tries to stop the course of the Cuban Revolution are appreciated, fundamentally directed towards the destabilizing maneuvers of the enemies of the homeland; however, this Fidel´s conviction that unity guarantees victory is present in the battle that has been waged, and is still being waged, against COVID-19, where the people, organized in various sectors, continue to obtain positive results against this pandemic.

Technology and principle of improving solubility of Dioscoreae Rhizoma formula granules based on powder modification / 中国中药杂志

The powder modification technology was used to improve the powder properties and microstructure of Dioscoreae Rhizoma extract powder, thereby solving the problem of poor solubility of Dioscoreae Rhizoma formula granules. The influence of modifier dosage and grinding time on the solubility of Dioscoreae Rhizoma extract powder was investigated with the solubility as the evaluation index, and the optimal modification process was selected. The particle size, fluidity, specific surface area, and other powder properties of Dioscoreae Rhizoma extract powder before and after modification were compared. At the same time, the changes in the microstructure before and after modification was observed by scanning electron microscope, and the modification principle was explored by combining with multi-light scatterer. The results showed that after adding lactose for powder modification, the solubility of Dioscoreae Rhizoma extract powder was significantly improved. The volume of insoluble substance in the liquid of modified Dioscoreae Rhizoma extract powder obtained by the optimal modification process was reduced from 3.8 mL to 0 mL, and the particles obtained by dry granulation of the modified powder could be completely dissolved within 2 min after being exposed to water, without affecting the content of its indicator components adenosine and allantoin. After modification, the particle size of Dioscoreae Rhizoma extract powder decreased significantly, d_(0.9) decreased from(77.55±4.57) μm to(37.91±0.42) μm, the specific surface area and porosity increased, and the hydrophilicity improved. The main mechanism of improving the solubility of Dioscoreae Rhizoma formula granules was the destruction of the "coating membrane" structure on the surface of starch granules and the dispersion of water-soluble excipients. This study introduced powder modification technology to solve the solubility problem of Dioscoreae Rhizoma formula granules, which provided data support for the improvement of product quality and technical references for the improvement of solubility of other similar varieties.
