ABSTRACT
Screening and evaluating the diseases responding specifically to traditional Chinese medicine （TCM） will help to highlight the advantages of TCM treatment， and the evaluation method should be standardized with consideration to the unique characteristics of the diseases. The incidence of Sjögren's Syndrome （SS） is increasing year by year， while the pathogenesis of this disease remains unclear. Modern therapies for this disease include biological agents and immunosuppressants， which generally have unsatisfactory efficacy. The TCM treatment of SS focuses on the harmony of the physical and mental health. The Rheumatology Branch of the China Association of Chinese Medicine organizes experts in TCM， Western medicine， and evidence-based medicine to form working groups. Delphi method and bibliometric method were used for analysis， and SS was selected as a disease responding specifically to TCM. Furthermore， the evaluation system was established for this disease， and the consensus regarding this disease was reached after seminar discussion. This paper summarized the whole process of the evaluation of the advantages of TCM treatment of SS. First， because TCM atomization is widely used in clinical practice and enriches TCM administration methods， this therapy is included after other non-drug therapies were taken as characteristic therapies. Second， the evaluation indicators of therapeutic effect should be determined with consideration to international acceptance and the current research status. Third， the expression method should be accurate， standardized， and objective， highlight the natural advantages of TCM， and avoid arbitrary extension. This paper provides a reference for clinicians to explore other diseases responding specifically to TCM.
ABSTRACT
Resumen El síndrome de intestino corto es una entidad de baja incidencia en los pacientes pediátricos, pero se asocia con elevadas tasas de morbimortalidad. El abordaje de estos pacientes por un equipo interdisciplinario de expertos enfocados en la rehabilitación intestinal mejora los resultados a corto y a largo plazo. Entre los recursos disponibles para el tratamiento se incluye el teduglutide, un análogo del péptido similar al glucagón tipo 2 (GLP-2) elaborado mediante técnicas recombinantes. Por medio de la aplicación del método Delphi, a partir de la evidencia disponible y de la experiencia de los autores, se proponen recomendaciones para el uso de teduglutide, dirigidas a los profesionales de la salud que tratan a los pacientes pediátricos con síndrome de intestino corto, así como a las autoridades sanitarias.

ABSTRACT
@#Introduction: Food and fitness levels are key factors required to maintain functional life. Hence, nutrition education is crucial in spreading awareness among Sports Science students. There is a paucity of plant-based nutrition knowledge and plantbased culinary skills for fitness locally. Therefore, this study aimed to develop a valid Plant-Based Culinary Nutrition Model (PBCNM) with nutrition knowledge and basic culinary skills to improve fitness among Sports Science students. Methods: This exploratory sequential mixed method study consisted of 2 phases. In Phase 1, a three-round modified Delphi method was conducted with 13 experts to generate a questionnaire that was validated. Lawshe worksheet determined the content validity ratio (CVR) for an item. Content validity index (CVI) for each section and the overall instrument was calculated. In Phase 2, quantitative data collection and analysis addressed the research questions and research gaps leading to model development. A total of 271 undergraduate Sports Science students at higher learning institutions were recruited as respondents. Results: In Phase 1, CVR of the overall survey was 1.0 and CVI was 0.834. Subsequently, the questionnaire was pilot tested for reliability and a Cronbach’s alpha score of 0.836 was obtained for the overall questionnaire. In Phase 2, the respondents’ mean and standard deviation score for the model’s components and needs was 4.21±0.73 for items 1-15. The integration of experts’ perspectives on the need of PBCNM for fitness and feedback from respondents resulted in the development of PBCNM. Conclusion: This study highlighted PBCNM as a helpful guideline for better fitness management.
ABSTRACT
【Objective】 To study the relationship between the key influencing factors and the short, medium and long term blood demand, so as to provide basis for building a blood demand prediction model with less prediction error and practical guidance. 【Methods】 Through literature research, the influencing factors of blood demand were preliminarily determined. Questionnaires were designed and distributed to relevant experts, and factor analysis was carried out on the survey results to obtain key influencing factors through Delphi method. 【Results】 Through literature research, 19 influencing factors of clinical blood demand were obtained, including policy factors, medical service demand, medical technology level, regional population, population characteristics, population structure, medical resource, number of beds, culture, natural environment, operation, patients outside the region, blood use in different departments, blood infusion, time trend, emergencies and disasters, the condition of disasters, hospitals in disaster area, limited diagnosis and treatment ability. Through Delphi method and data analysis, six key factors affecting blood demand were obtained, namely sudden disaster, medical resource, environmental factor, population, bed number and blood infusion. 【Conclusion】 The influence of key factors on clinical blood demand was divided into multiple hierarchies. Blood infusion and sudden disaster were short-term influencing factors. Medical resource, population and number of beds were medium influencing factors. Environmental factor was long-term influencing factor. Short, medium and long-term influencing factors were interrelated, and have different impacts on clinical blood demand. Based on the interaction relationship, a three-dimensional mathematical model of influencing factors of clinical blood demand was established, which provided a preliminary research basis for building a blood demand prediction model with less prediction error and practical guidance.
