RESUMEN
By searching the papers about medical ethics education in Chinese database CNKI and foreign database Web of Science Core Collection, and using the bibliometrics software CiteSpace to draw the knowledge map of medical ethics education at home and abroad, this paper conducted a quantitative and qualitative analysis of the evolution of hot spots and the development trend of medical ethics education research, and found that the development level of medical ethics education in the world varies greatly. China has experienced the development and evolution from medical ethics education to medical humanities, and its research hotspots mainly focus on the topics of "medical ethics" "medical education" "practice teaching" "medical humanities" "teaching reform" and so on. While foreign countries focus on "medical education" "clinical ethics" "hospice care" "health care" "global public health" "science and technology ethics" "organ transplantation" "curriculum construction" "health policy" and other topics. Through the comparative analysis of the development trend and the evolution of hot spots of education, this paper put forward theoretical reference direction for improving the medical ethics education system in China and further perfecting the discipline construction of medical ethics in China.
RESUMEN
<p><b>OBJECTIVE</b>To compare the dissolution properties of Ginseng micropowder and common powder in vitro and investigate the effect of micronization on dissolution of Ginseng.</p><p><b>METHODS</b>Five ginsenosides including Rg1, Re, Rf, Rb1, and Rb2 were determined by high performance liquid chromatography, and the dissolution curves of Ginseng micropowder and common powder were drawn.</p><p><b>RESULTS</b>The dissolution rates of ginsenosides from micropowder exceeded 90% within 5 min, significantly greater than that from common powder. But when the powders were packed in tea bags, the dissolution rates of ginsenosides were higher from common powder than from micropowder.</p><p><b>CONCLUSION</b>Micronization treatments can promote dissolution of ginsenosides from Ginseng.</p>
