The development history, the features and laws of guaranteeing medical supplies under emergency situation are introduced briefly. The allocation of resources, the key factors in management and the technique supply are described. By looking at the trend and the future work on how to guarantee medical supplies in the state of emergency, some conclusions can be made: guaranteeing medieal supplies in the state of emergency is a whole new field. Only when the experience is accumulated, and when the eoneepts and techniques from foreign countries are learned, the supplies for clinical and first aid to be delivered safely and in time can be guaranteed. Thus, the number of lives saved will be maximized.

Acute abdomen means a set of clinical emergency with acute abdominalgia as the primary characteristic symptom of onset,including others as the acute onset,quick symptom changes,severe illness,and oftenly need surgical treatment;therefore,acute abdomen ought to be designated within surgery domain.As interventional therapy is extensively applied in clinical medicine,now a days many victims of acute abdomen,especially those with ambiguous clinical diagnosis requiring an initial invasive examination(angiography,PTC,etc),should be referred to interventional therapy before taking an item of invasive measures.This new concept management has achieved good clinical curative effect and become one of the remarkable achievements in acute abdomen therapeutics.Such predominance finds proper expression in the following two aspects:(1)The evolution of contemporary medical iconography has made it possible to duely and accurately diagnose acute abdomen,and thus created a diagnostic predominance for us-interventionalists;(2)Intervention therapy is featured with its unigue minimal invasion and massive effectiveness,and thus provides high leading edge than conventional surgical operation.We believe that intervention management ought to become the first-choice for treating the above mentioned acute abdomen.(J Intervent Radiol,2006,15:193-194)

BACKGROUND: Dance-sport is a newly emerging sport item, integrating sport with music and dance. It not only develops physical diathesis and sport skills, but also actively affects psychological health of university students.OBJECTIVE: To analyze and observe the changes in psychological health, physical diathesis and musical cultivation after dance-sport training for university students.DESIGN: Cross-section investigation was designed, in which, the students in elective class of dance-sport were taken as objects.SETTING: Department of Physical Education of China University of Mining and Technology.PARTICIPANTS: Totally 116 students were collected from 2001' elective class of dance-sport in China University of Mining and Technology from September 2001 to January 2003. All of receptors selected dance-sport at the first time. Of 120 copies of Symptom Checklist 90 (SCL-90) were provided and 116 of those were returned, in which, 58 students were either male or female, aged averagely 19.7 years.METHODS: Questionnaire: SCL-90 was used to evaluate 9 main outcome measures, named psychological health, somatization, obsessive compulsive (o-c) symptoms, personal relations, depression, anxiety, hostility, phobism,paranoid ideation and metal disorder; in which, 5 grades were adopted,named 1, 2, 3, 4 and 5 grades, to represent no, mild, moderate, severe and extremely severe impacts successively. Test: according to stipulated music rate, cardiac rate and music were tested so as to observe the changes in physical diathesis and capacity of musical rhythm understanding. Simultaneously, literatures were looked up on education, psychology and physical education to provide theoretic evidence for this paper. The questionnaire was provided before and after the semester respectively and returned for music test. Test on cardiac rate was performed at the end of semester.MAIN OUTCOME MEASURES: Comparison among the results of two SCL-90 evaluations, positive number and total average result in receptors and national norm. Result of cardiac rate and music test in receptors.RESULTS: Totally 120 copies were provided, 116 of them were returned and the rate of return was 97%. ① Result of SCL-90: At the end of semester, the results of depression, hostility and positive number of 9 items in the checklist were lower remarkably than those before the semester (P ＜ 0.01-0.05); the results of somatization, interpersonal sensitivity, depression, hostility and total average result were lower remarkably than national norm (P ＜ 0.01-0.05). ② Dance-sport and physical diathesis:Among various dances in sport, the highest, lowest and average cardiac rates were (115-194) times/minute, (114-140) times/minute and (138-169) times/minute successively. The amount of exercise is over moderate level and it benefits cardiac vascular system, functions of heart and lung,endurance, etc. Long-term exercise will be good for the physique. ③ Impacts of dance-sport on music cultivation: Before the class, 93.1% of students did not understand musical rhythm or they understood the rhythm,but it is hard for their steps followed the rhythm. After the course of dance-sport, only 2.5% of students did not understand and follow musical rhythm.CONCLUSION: Dance-sports improves not only psychological health and physical diathesis of students, but also their musical and art cultivation.It is mass sports activity, benefiting the health both physically and mentally.

Four methods for evaluating the academic impact of scholars were described according to their literature information, including subjective evaluation method, bibliometric method, social network analysis and comprehen-sive evaluation method .Their development trend was studied by analyzing their characteristics and applications .

Certain public service pre-school teachers have been trained as vision screeners of children. However, there are no studies that assessed the knowledge and skills retention of these screeners. This study determines the level of knowledge retention among pre-school teachers who have been trained to perform vision screening on children. In 2013, 180 KEMAS pre-school teachers were recruited in a vision screening training which included both theory and practical sessions. Teachers were assessed through a theory test which comprised of 15 questions, firstly a category on the preparations needed for vision screening and secondly on the implementation of vision screening. They were then asked to conduct pre-school vision screening annually at their working premises. In 2016, 136 teachers who had been involved in the earlier program were recruited as subjects in this study. All these subjects answered the same set of theory test questions used in 2013. The Student’s t-test result indicated that the mean theory test scores obtained by the pre-school teachers in 2013 (84.3 ± 7.8) differed significantly with the mean scores obtained in 2016 (67.5 ± 11.3) (p < 0.001). The mean scores in 2013 for questions in the first and second categories were 4.5 and 4.4, decreasing to 4.2 and 3.7 in 2016. The knowledge level of pre-school teachers thus decreased with time and this effect was found significant after 3 years. There is therefore a need to conduct re-certification training, so that the screening conducted by these pre-school teachers remains effective and in accordance with established standards.

Objective To investigate the clinical effect of minimally invasive plate fixation in the treatment of calcaneal fractures.Methods 68 patients with calcaneal fractures were selected as the research subjects,they were randomly divided into the control group and observation group,34 cases in each group.The control group received open reduction and plate internal fixation,while the observation group was treated with minimally invasive plate fixa-tion.The clinical results and complications of the two groups were observed.Results The excellent and good rate was 94.1 2% in the observation group,which was significantly higher than 79.41 % in the control group,the difference was statistically significant(χ2 =9.397 6,P <0.05 ).The Bohler angle and Gissane angles in the control group were (28.67 ±2.04)°,(1 21 .87 ±8.23 )°after treatment,which were significantly higher than (6.45 ±1 .21 )°, (1 01 .65 ±8.56)°before treatment.After treatment,the Bohler angle and Gissane angles of the observation group were (32.56 ±3.25 )°,(1 29.45 ±1 2.86)°,which were significantly higher than (6.36 ±1 .26)°,(1 01 .54 ± 8.27)°of the control group,the differences were statistically significant(P <0.05),and the increase of Bohler angle and Gissane angle of the observation group was more obvious than the control group.The incidence rate of complica-tion in the observation group was 2.94%,which was lower than 8.82% in the control group,the difference was statis-tically significant(χ2 =3.923 7,P =0.047 7).Conclusion Minimally invasive plate fixation in the treatment of cal-caneal fractures has significantly smaller incision,and can reduce the incidence of complications,it is worthy of clini-cal application.
