In order to provide an experimental evidence for clinical utility, we undertook a series of experimental studies of glucocorticosteroid to treat closed head injury and gun shot brain wound, For studies of closed injury in rats, there were four groups as follows: Group 1: methyl prednisone 30mg/kg (MPG); Group 2: dexamethasone 5 mg/kg (HDMG): Group 3: dexamethasone0.5mg/kg (LDMG); and Group 4: normal saline as a control group (CG) For study of gun shot wound of brain, The dogs were divided into three groups, Grup 1 (wound group, n=8); Group 2 (treated group, n=7) and group 3 (control group, n=7). After injury, the vital signs were observed, the water content of the brain and Even' s blue level were measured and the brain were examined under optical and electronic microscopy, All results proved that secondary traumatic edema in the animals used high dose glucocotricosteroid were much more slight

The left ventricular bands of isolated human heart were studied by microscopy, echocardi ography and gross anatomical method. The results indicate that the structures of the bands were those commonly observed in human heart. They could be classified into two types: myo-bands and tendinous bands. However, we could only differentiate the “bands whose” diameter was more than 1.5mm with Aloka-SSD720 echocardiograph (made in Japan). we suggest that the resolution of the instrument we used was too low, and this might be the main reason that the detection of left ventricular bands was much lower than the incidence, we classified these bands according to the adhering points and diameters of bands.In this paper, the forming factors of bands and their clinical significance are also discussed.

The effect of high dos; dexamethasone(5mg/kg wt, intravenous injection)to prevent and treat the secondary pathological damage of craniocerebral injury was studied in animal models of craniocerebral injury caused by high-velocity missiles in dogs.We observed ths physiological changes, analyzed the value of serum and. cerebrospinal fluid lactate dehydrogenase, estimated the permeability of blood brain barrier (BBB) and studied brain pathology by light and electron microscopy.The results suggest high dose dexamethasone can help to restore ths structure and function of BBB, protect brain cells as well as lessai the secondary pathological damage in tha respiratory and circulatory systems and reduce th production of lipoptrox-ides(LPO).

Through expounding the connotation of clinical physicians'humanistic medicine practice ability,this paper pointed out that building the evaluation index system should abide by the four principles of systematicness,scientificity,guidance and feasibility.Constructing the evaluation index system of clinical physicians' humanistic medicine practice ability included 4 first-level indicators,13 second-level indicators and 47 third-level indicators,which is beneficial to promoting the physicians' humanistic medicine practice ability and is conducive to improve the human resource evaluation and management of hospitals.

Interventional radiology is a new kind of minimally-invasive therapeutics that has developed on the basis of radiological imaging diagnosis.Interventional radiology is defined as a clinical subject that carries out the specific diagnosis and treatment under the guidance of medical imaging equipment and with the help of puncture needle,guide wire,catheter,etc.The interventional radiology categories include interventional diagnosis and interventional therapy.Interventional medicine is defined from the perspective of clinical application,while interventional radiology is defined from the technical characteristics of diagnosis and treatment.《of Interventional Radiology》 and the upcoming 《Journal of Interventional Medicine (English version)》 will become the professional sister journals in interventional academic field,which will provide important support for promoting the development of interventional medicine in China and for enhancing the international influence power of Chinese interventional medicine.

The authors analyzed the current predicament of medical human resources and seek the deficiencies and problems that exist in the medical moral education system .Based on this , this paper pointed out that it should change the medical ethics education ideas , enhance medical ethics cultural identity; based on the health industry demand , broaden the content of the medical ethics education;to develop a new mode of medical ethics education , perfect the evaluation system of medical ethics and health industry demand , provide new guidance for medical eth-ics education .

Objective: To study the urban and rural difference impacts of aging on health care expenditure. Methods: Using 2002-2011 panel data of 31 provinces throughout the country to build fixed effect models for the urban and rural areas and make comparative analysis. Results: For urban and rural areas, there are significant differences in the impact of aging on health care expenditure, the estimated coefficients are 0.13 and 0.48 respectively. Conclusion:Under the background of the aging process, it needs to strengthen the construction of rural medical insurance system in China, increase financial support and rural health resource allocation.

The planned digital textbook Human Parasitology, the first of its kind, published by People's Medical Publishing House is an important medical education effort that features the inte-gration of digital resources. This paper introduces the digital textbook construction goal, namely using paper-based textbook for five-year undergraduates as blueprint to reasonably display the digital re-sources based on the features of the discipline. The advantages of this digital approach over traditional paper-based textbook in demonstrating parasitic morphology, lifecycle, pathogenesis, diagnosis, epi-demiology and control are discussed. Valuable experiences in planning and constructing this digital textbook are to be shared.

As a new way,on-line bid & purchase expands and deepens the bid principle of "Honest,Justice,Public". This paper analyzes the characteristics of on-line bid,puts forward the centralized bidding frame based on Internet,and optimizes the bid procedure. The study not only makes the on-line bid more effective and strict but also makes the bid result more convincing.
