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.

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 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.

Optic coherence tomography (OCT) is one of the most rapid developing technologies in ophthalmology. OCT angiography (OCTA) has been made possible by the development of even faster scanning and sampling techniques, which is the next milestone after stratus OCT and spectral domain OCT. Without the need of injection of the contrast agent, OCTA is capable of providing a three-dimensional reconstruction of the perfused microvasculature within the retina and choroid by detecting the motion of scattering particles such as erythrocytes within sequential OCT cross-sectional scans performed repeatedly at the same location of the eye with different analysis algorithms. Comparing to fundus fluorescein angiography and indocyanine green angiography, with improved OCT technology and understanding, OCTA has showed certain advantages to diagnose retinal and choroidal diseases, especially macular vascular diseases. It is important to establish the contributions that OCTA can make to diagnosing, managing and understanding of ocular fundus diseases.
