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 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.

OBJECTIVE:To investigate the improvement effect of Eucalyptol enteric soft capsule on mice with lipopolysaccha-ride(LPS)-induced acute lung injury(ALI). METHODS:60 mice were randomly divided into blank control group,model control group,Eucalyptol enteric soft capsule low-dose,medium-dose,high-dose groups(100,300,900 mg/kg),12 in each group. Mice in administration groups were intragastrically given relevant medicines,mice in blank control group and model control group were intragastrically given equal volume of normal saline(0.1 mL/10 g). After 2 h of administration,except for the blank control group, ALI was induced in other groups by atomized LPS. After 6 h of modeling,the mice were sacrificed,alveolar lavage fluid(BALF) and lung tissue were taken. Morphological changes of lung tissue were observed under microscope;number of total cells,neutro-phils in BALF were calculated by blood cell count plate and staining by wright-giemsa respectively. Total protein concentration in BALF supernatant was detected by BCA method;TNF-α,IL-6 contents in BALF supernatant were determined by enzyme-linked immunosorbent assay. RESULTS:Compared with blank control group,lung tissue of mice in model control group showed obvious pathological damage and severe pulmonary edema;number of total cells,neutrophils in BALF,total protein concentration and TNF-α,IL-6 contents in BALF supernatant were significantly increased(P<0.01). Compared with model control group,pathologi-cal damage in lung tissue of mice was obviously improved in Eucalyptol enteric soft capsule high-dose group,number of total cells,neutrophils in BALF,total protein concentration and TNF-α,IL-6 contents in BALF supernatant were significantly decreased (P<0.05);and there were no significant differences in other groups (P>0.05). CONCLUSIONS:High-dose Eucalyptol enteric soft capsule can obviously improve LPS-induced ALI of mice.

[Summary] The isolated dissection of the superior mesenteric artery ( IDSMA) was once considered to be a rare disease .In recent years , a growing number of cases of IDSMA have been reported , especially by Chinese authors , because of the increasing use of contrast-enhanced computed tomography scans .To understand the real domestic status of IDSMA , the Chinese-language literatures were searched, and the clinical characteristics and treatment of IDSMA were analyzed .

Objective To evaluate the effects of selective mesenteric angiography with continuous papaverine perfusion for the diagnosis and treatment of non-occlusive mesenteric ischemia(NOMI).Methods Eighteen patients with NOMI underwent selective superior mesenteric arteriography and papaverine perfusion via the SMA simultaneously were analized retrospectively.Results Fifteen out of the 18 cases recovered;2 cases underwent laparotomy;1 case died within 10 days.Conclusion Selective superior mesenteric arteriography with continuous papaverine perfusion is an effective diagnostic and therapeutic method for non-occlusive mesenteric ischemia.(J Intervent Radiol,2006,15:209-212)

The function of the nervous system is largely determined by the communication between neurons and glial cells.The interaction of complex signaling pathways between neurons and glial cells involves in a variety of signaling molecules.Purines and the purinergic receptors play a crucial role in the process of the interaction.For a long time, the study on the central nervous system is mainly focused on neurons, while glial cells are mainly used as support cells or in response to brain injury to provide a guiding role.The latest research shows that glial cells play an important role in the occurrence and development of nervous system diseases.We will summarize the function of purinergic receptors in the interaction of neurons and glial cells and in neurological diseases.

In order to improve the scientificity and rationality of materiel management,we developed the materiel management system and realized the computerizing of material management. This system can solve all problems in material computerizing which occur during the process from the material application to its abandonment. Aiming at solving disadvantages in human management,the utilization of this system will greatly reduce the staff's work load,enhance the working efficiency and make the material management standardized.
