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)

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.

Objective To evaluate the value of coronary arteriongraphy(CAG)in diagnosing angina.Methods 219 patients with angina in clinical analysis were selected and divided into 2 groups:the stable angina(SA)group and unstable angina(UA)group.They all were accepted CAG first time.Then analysis were carried out between clinical diagnosis and results of CAG.Results The total positive rate of CAG in diagnosing angina is 58.90%.The positive rate of SA group(56.52%)shows no significant difference with that of UA group(60.00%).Single vessel lesion and multiple vessels lesion of SA group have little difference,however,the main coronary artery lesions of UA group is single vessel.Conclusions CAG is extremely important in diagnosing angina,but it has its own limit.Experience and new technique should be applied to retrieve locatization of CAG.
