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)

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.

Objective To analyze the literature of two core periodicals ,Military Medicine of the USA and Journal of the Royal Army Medical Corps of the UK,in order to highlight some important authors ,research institutes and some hot spots in the field of military medicine .Methods Citespace and Excel were used to analyze the data of authors institutes , keywords and citation frequency of the collected records .Results and Conclusion The core authors and critical research institutes are mainly from the USA and UK .America is absolutely taking the leading position in research on military medicine that focuses on injury risk factors , trauma and care , mental health , veteran affairs , military epidemiology and prevention .The results are of referential value for researchers and research administrators to find out about the main core authors ,research institutes and hot spots in military medicine .

OBJECTIVE:To provide references for the establishment and evolvement of national drugs policy as well as its related research.METHODS:The contents of the new drug strategy and the contents subjected to regular monitoring and evaluation as well the cooperative implementation of the strategy etc were introduced,and its implication for China was analyzed.RESULTS & CONCLUSIONS:The accessibility to essential drugs can be guaranteed with the help of WHO's new drugs strategy,likewise,the accessibility to essential drugs in China can't be realized without the great support of the national drugs policy and the sustainable efforts of both the government and the society.

[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 .

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 .

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.

Objective To investigate the effect of intranasal instillation of insulin with different doses on cognitive function in patients with Alzheimer disease (AD).Methods Sixty-three AD patients were collectcd.According to the order of doctor's office visiting,they were divided into insulin 1 group (21 cases,intranasal instillation of insulin 20 U,2 times per day),insulin 2 group (21 cases,intranasal instillation of insulin 40 U,2 times per day) and placebo group (21 cases,intranasal instillation of physiological saline,2 times per day).Mini-mental state examination scale (MMSE) and Rivermead behavioural memory test second edition (RBMT Ⅱ) were used to evaluate the improvement of cognitive function after 3 months and 6 months.Results Before treatment,the scores of MMSE and RBMT Ⅱ in insulin 1 group were (20.2 ± 2.3) and (17.2 ± 1.9) scores,in insulin 2 group were (20.7 ± 2.8) and (16.5 ± 1.9) scores.After treatment for 3 months,the scores of MMSE and RBMT Ⅱ in insulin 1 group were (21.8 ± 3.2) and (19.2 ± 2.0) scores,in insulin 2 group were (21.6 ± 3.5) and (18.1 ± 2.0) scores.The scores of MMSE and RBMT Ⅱ in insulin 1 group and insulin 2 group significantly improved compared with those before treatment (P ＜ 0.05 or ＜ 0.01).But the scores of MMSE and RBMT Ⅱ in placebo group were significantly aggravated,(18.9 ± 3.8) scores vs.(20.9 ± 2.5) scores,(15.2 ± 2.1) scores vs.(16.1 ± 2.0) scores,P ＜ 0.05.After treatment for 6 months,the scores of MMSE and RBMT Ⅱ in insulin 1 group were (22.5 ± 3.3) and (20.5 ± 2.0) scores,in insulin 2 group were (22.7 ± 3.1) and(19.8 ± 1.9) scores,and in placebo group were (17.9 ± 4.5) and(14.7 ± 2.0) scores.The scores of MMSE and RBMT Ⅱ in insulin 1 group and insulin 2 group were significantly better than those in placebo group (P ＜ 0.01).Conclusion Intranasal instillation of insulin can improve cognitive disorders in patients with AD.

Radiotherapy is an important means for curing nasopharyngeal carcinoma at present.Howev-er,how to handle the focus residual,relapse and metastasis after the radiotherapy of nasopharyngeal carcinoma is still a hot potato.125 I seed implantation is regarded as a member of the comprehensive therapies.Its feasibili-ty for curing such cancer has already been confirmed in the experimental research of the cytology and zoology, and it has been applied in the focus residual,relapse and metastasis after the radiotherapy.Furthermore,its clinical therapy effect has been acknowledged.
