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.

Objective To explore the CT perfusion imaging with acetazolamide (ACZ) challenge test in the diagnosis of chronic cerebral insufficiency.Methods 100 patients undergoing health examination in our hospital from Aug 2009 to Feb 2011 were chosen,52 patients diagnosed as chronic cerebral insufficiency were defined as the case group,and the remaining 48 cases of healthy elderly people were defined as the control group.The brain CT perfusion imaging with acetazolamide challenge test,and the cerebral blood flow (CBF),cerebral blood volume (CBV),mean transit time (MTT) and time to peak (TTP) in anterior cerebral artery (ACA),middle cerebral artery (MCA)cortical branch supply area,MCA deep perforator region,posterior cerebral artery (PCA) and pons part blood supply area were examined in the elderly people of two groups.Results CBV and CBF values in ACA,MCA cortical branch supplyarea,MCA deep perforator region,PCA and pons part blood supply area after ACZ stimulation were significantly lower in case group than the control group (t=3.57,3.39,9.34,11.04,4.21,5.99,9.91,11.10,6.66,9.97,P＜0.01 or 0.001),while MTT and TTP values were significantly higher in case group than in the control group (t =7.21,6.94,16.53,4.82,11.67,6.46,6.11,6.71,6.87,4.82,all P＜ 0.001),CBV and CBF values in the control group were significantly higher after ACZ excitation than before the challenge (t=6.44,6.86,9.72,10.99,7.03,6.33,12.48,14.82,8.98,12.03,all P＜0.001),and the MTT and TTP values in the control group were significantly lower after ACZ excitation than before the challenge (t=7.98,5.77,17.29,8.28,9.74,7.01,7.52,6.32,6.01,5.54,all P＜0.001).Conclusions CT perfusion imaging with acetazolamide challenge test can increase the detection rate of chronic cerebral insufficiency with better clinical significance,and is worthy of promotion.

Objective To explore the effect of bionic urine bags on dysuria in stroke patients and improve the effect of bladder function training. Methods Forty patients with urinary incontinence were selected and randomly divided into control group (n=46) and observation group (n=44) by random number table. The patients in the control group were treated with Kangwei anti-reflux urine bags and the urine was discharged every 3 hours at daytime, once every 4 hours at night. The patients in the experimental group were treated with OT-U bionic urine bags for drainage urine, the threshold of urine bag pressure set:when the bladder pressure reached more than 35cm H2O, the bladder urine flowed into the urine bag. The two groups were compared in view of catheter catheterization time, urination after urination time, self-urination, re-intubation rate, urine overflow, urinary tract infection. Results The duration of indwelling catheters in the observation group was significantly higher than that of the control group (P <0.05). The rates of re-intubation and urinary tract infection were significantly lower as well (P<0.05). Conclusion Biomimetic urine bag can effectively promote the training of bladder function, shorten the time of indwelling catheter and reduce the occurrence of urinary tract infection after extubation.
