Ecological construction of ESP curriculum system in medical schools under perspective of learning science / 中华医学教育探索杂志

English for specific purpose (ESP) courses for the postgraduates in medical schools have both physical and social attributes, with emphasis to improve practical language learning of medical specialties. It's an effective way to develop the English language application ability of high-level medical college students by constructing an ESP teaching and learning ecological system with professional and social contextual characteristics. In this study, through design-based implementation research, scenario simulation class was designed and implemented to accomplish task-based language teaching and learning. Further discussions on how to integrate blended and interrelated classes, on how to define combined and interactive teachers' role were explored. Based on the teaching and learning practices, organically combining the innovative curriculum concept with the construction of ESP ecological system effectively directs the practical application of the ESP class under the perspective of learning science, and verifies the feasibility of the ecological construction of ESP curriculum system.

Analysis of status quo of outcome indicators of randomized controlled trials in treatment of acute ischemic stroke with acupuncture in recent three years / 中国中药杂志

To analyze the use of outcome indicators of randomized controlled trial(RCT) of acupuncture in the treatment of acute ischemic stroke in recent three years, so as to provide a basis for building a study on the core outcome indicators for the treatment of acute ischemic stroke with acupuncture. The RCTs of acupuncture treatment for acute ischemic stroke in recent three years were collec-ted through computer retrieval of eight Chinese and English databases and two clinical trial registries at home and abroad. Literature was screened out, and data was extracted. Risk of assessment bias tool Cochrane 6.1 was used for bias risk assessment, outcome indicators were summarized and analyzed. A total of 47 RCTs were included, and 3 studies were trials registration scheme. Outcome indicators were divided into 6 categories according to functional attributes, namely physical symptoms/signs, physical and chemical examination, quality of life, traditional Chinese medicine symptoms/syndromes, safety events and long-term prognosis. The study found that in addition to the common problems in previous studies covered by the status quo of outcome indicators selection of RCT of acupuncture in the treatment of acute ischemic stroke, there were also the other problems as follows: emphasis on macroscopic efficacy indicators but neglect of acupuncture specific indicators, lack of characteristic indicators and economic indicators of traditional Chinese medicine therapy, and unification of indicators measurement tool and measurement time point. In the future, the outcome indicators set for the treatment of acute ischemic stroke with acupuncture shall be established, and the core outcome indicators set shall be in line with the characteristics of traditional Chinese medicine treatment.

An Aspect of the History of Medicine in Ancient Korea as Examined through Silla Buddhist Monks'Annotations on the “Chapter on Eliminating Disease (除病品)”in the Sutra of Golden Light (金光明經, Suvarṇabhāsa-sūtra) / 의사학

Nearly nothing is known of medicine in ancient Korea due to insufficient materials. With several extant prescriptions and esoteric methods of treating diseases alone, it is impossible to gauge in depth the management of medicine during this period. If one exception were to be cited, that would be the fact that the annotations for understanding the contents on Indian medicine in the “Chapter on Eliminating Disease” in the Sutra of Golden Light, a Buddhist sutra originating from India, reflected the medical knowledge of Buddhist monks from Silla (新羅, 57 BC-935 AD) who were active immediately after the nation's unification of the two other kingdoms on the Korean Peninsula (668 AD) such as Wonhyo (元曉, 617-686 AD), Gyeongheung (憬興, 620?-700? AD), and Seungjang (勝莊, 684-? AD). Along with those by other monks, these annotations are collected in the Mysterious Pivot of the Sutra of Golden Light (金光明經最勝王經玄樞), which was compiled by Gangyō(願曉, 835-871 AD), a Japanese monk from the Heian era (平安, 794-1185 AD). Representative versions of the “Chapter on Eliminating Disease” in the Sutra of Golden Light include: a classical Chinese translation by the Indian monk Dharmakṣema (曇無讖, 385-433 AD); the eight-volume edition by Chinese monk Baogui (寶貴), which differs little from the preceding work in terms of the contents of the “Chapter on Eliminating Disease”; and the ten-volume edition by Yijing (義淨, 635-713 AD), who had full-fledged knowledge of Indian medicine. When the contents of the annotations thus collected are examined, it seems that Wonhyo had not been aware of the existence of the ten-volume edition, and Gyeongheung and Seungjang most certainly used the ten-volume edition in their annotations as well. Especially noteworthy are Wonhyo's annotations on the Indian medical knowledge found in the “Chapter on Eliminating Disease” in the Sutra of Golden Light. Here, he made a bold attempt to link and understand consistently even discussions on Indian and Buddhist medicine on the basis of the traditional East Asian medical theory centering on the yin-yang (陰陽) and five phases (五行, wuxing). In accordance with East Asia's theory of the seasonal five phases, Wonhyo sought to explain aspects of Indian medicine, e.g., changes in the four great elements (四大, catvāri mahā-bhūtāni) of earth, water, fire, and wind according to seasonal factors and their effect on the internal organs; patterns of diseases such as wind (vāta)-induced disease, bile (pitta)-induced disease, phlegm (śleṣman)-induced disease, and a combination (saṃnipāta) of these three types of diseases; pathogenesis due to the indigestion of food, as pathological mechanisms centering on the theory of the mutual overcoming (相克, xiangke) of the five phases including the five viscera (五藏, wuzang), five flavors (五味, wuwei), and five colors (五色, wuse). They existed in the text contents on Indian medicine, which could not be explicated well with the existing medical knowledge based on the theory of the five phases. Consequently, he boldly modified the theory of the five phases in his own way for such passages, thus attempting a reconciliation, or harmonization of disputes (和諍, hwajaeng), of the two medical systems. Such an attempt was even bolder than those by earlier annotators, and Wonhyo's annotations came to be accepted by later annotators as one persuasive explanation as well. In the case of Gyeongheung and Seungjang, who obtained and examined the ten-volume edition, a new classical Chinese translation produced following Wonhyo's death, annotated the “Chapter on Eliminating Disease” based on their outstanding proficiency in Sanskrit and knowledge of new Indian and Buddhist medicine. This fact signifies that knowledge of the eight arts (八術) of Ayurvedic medicine in India was introduced into Silla around the early 8th century. The medical knowledge of Wonhyo, Gyeongheung, and Seungjang demonstrates that intellectual circles in contemporary Silla were arenas in which not only traditional East Asian medicine as represented by works such as the Inner Canon of the Yellow Emperor (黃帝內經, Huangdi Neijing) but also Indian medicine of Buddhism coexisted in almost real time.

Diferencias cinéticas de las plasminas de ocho especies mamíferas: activaciones y secuencias de los terminales-N / Kinetic Differences of Plasmins from Eight Mammalian Species: N-Terminal Activations and Sequences / Diferenças cinéticas das plasminas de oito espécies mamíferas: ativações e sequencias dos terminais-N

El artículo determina los parámetros cinéticos de las plasminas de ocho especies de mamíferos y sus terminales-N. Los ocho plasminógenos fueron purificados por los mismos métodos (cromatografías de afinidad e intercambio iónico), y activados con urocinasa, partiendo de una concentración común y su cinética valorada según las coordenadas de Lineweaver-Burk. Para esto se utilizó la cinética enzimática de Michaelis Menten, ampliamente usada en el estudio de enzimas. Todos los plasminógenos mostraron una pureza superior al 95% y una banda de 92 kDa en la electroforesis, al comparar con el estándar de peso molecular utilizado. Las plasminas del equino y canino mostraron la misma K M por el sustrato cromogénico (0,438 mM), siendo esta la de mayor afinidad en este estudio y la humana la de menor afinidad (5,3 mM). También fueron determinadas la constante catalítica y la velocidad de conversión del sustrato cromogénico a producto. Los terminales-N de los plasminógenos de las ocho especies fueron determinados, y se encontraron diferencias entre el humano y los animales; así mismo entre algunos animales. Solo el porcino y el ovino no mostraron diferencia alguna en su terminal-N (DPPDDY). Se demostró la unificación del método de purificación de los plasminógenos para cualquier especie, las diferencias cinéticas de las ocho plasminas estudiadas, y las similitudes y diferencias en la secuencia de los terminales-N de las ocho especies.

The paper determines the kinetic parameters of plasmins from eight species of mammals and their N-terminals. They were purified by the same methods (affinity chromatography and ion exchange) and activated with urokinase, starting from a common concentration and its kinetics judged according to Lineweaver-Burk coordinates. For such purpose, MichaelisMenten enzyme kinetics, which is widely used in the study of enzymes, was implemented. When compared with the molecular weight standard used, all plasminogen showed a purity exceeding 95% and a 92 kDa band on electrophoresis. Equine and canine plasmins showed the same K M due to the chromogenic substrate (0.438 mM), this being the one with the highest affinity in this study, and the human being the one with the lower affinity (5.3 mM). The catalytic constant and the conversion rate of the chromogenic substrate to product were also determined. The N-terminals of the plasminogens of the eight species were determined, and differences were found between humans and animals, as well as between some animals. Only pigs and sheep showed no differences in their N-terminal (DPPDDY). The unification of the method for purification of plasminogens for any species was demonstrated, as well as the kinetic differences of the eight plasmins studied and the similarities and differences in the sequence the N-terminals of the eight species.
