Objective To achieve the DICOM3.0-based management system for medical image and data. Methods Under the context of Microsoft Windows XP, Microsoft Visual C++.NET, LeadTools V14.5 development SDK and Microsoft SQL Server 2000 were used to actualize a medical image data management system based on DICOM 3.0 standard. Results This system could store and read the DICOM 3.0 standard -based medical image correctly and establish the corresponding control of authority to different users. Conclusion This system is easy for maintenance and operation with convenient search function.

Current curriculum provision and teaching patterns of computer science in medical school has been far behind the requirements of clinical and research works, which restricted the develop-ment of medical talents to a large extent. According to the experiences of teaching practice,Department of Computer Science in Chongqing Medical University launched reform on medical computer science from aspects of teaching practice,curriculum provision,teaching methods and evaluation methods. Computer courses were opened according to students' computer knowledge and the profession. Task-based teaching and comprehensive evaluation methods were employed in order to improve the teaching quality.

Objective To explore the related factors of senile acute pulmonary thromboembolism(PTE) patients,and to observe the prognosis and analyze the strategy of control and prevention to reduce the incidence. Methods 50 elderly patients with acute PTE were selected,related factors were analyzed by using the retrospective investigation,and the prevention and control were administrated.Results The mainly disease occurred of the elderly patients with acute PTE were combined with chronic diseases 42% (21 /50),with lower extremity DVT 26.00%(13 /50)and with recent trauma,fracture and operation 20%(10 /50).Elderly patients with acute PTE who were ≥70 years of age and lying in bed the time≥1 month,were 58%(29 /50)and 62%(31 /50),which were higher than those of the other age <70 years old and lying in bed time <1 month of patients,the difference was statistically signifi-cant(χ2 =9.26,9.80,all P <0.05).Conclusion The related risk factors for elderly patients with acute PTE mainly correlate with age,lying in bed time,chronic diseases,patients with lower extremity DVT and recent trauma,fracture, operation,the variety of factors and overlap each other.Mastering the variety factors of PTE in the nursing process,and taking effective measures to prevent and control the factorscan reduce or avoid the occurrence of acute PTE,and im-prove the prognosis of the patients.

OBJECTIVE To cultivate central supply unit member's custom of watching detail and dealing with everything carefully. To enhance central supply unit work's quality and efficiency,and decrease the phenomenon of article sterilized overdue and nipping tool's scathe. METHODS To organize study and enhance the cognition. To constitute regulations,systems and operation rule. To investigate the condition of medical instrument utilized,and pay attention to detail service for packaging sterilization. RESULTS The rate of overdue sterilized article decreased from 0.008% to 0.001%. The number of nipping tool's injuries decreased from 18 in 24 to 2 in 22 when the detail management was actualized. The rate of injury decreased from 75.0% to 9.09%. CONCLUSIONS In order to ensure the quality of asepsis of articles,we need to alter our conceptions,strengthen our responsibility,servicing more initiatively and carefulness.

Protein separation method is the core factor of the proteomics strategy. There are three methods for the protein separation, include two dimensional gel electrophoresis, liquid-phase electrophoresis and Mass Spectrometry, and protein-chip. In this article, the principles, processos, and development on the three separation protein methods.were reviewed.

Objective:To observe the sedation effects of midazolam on maxillofacial postoperative patients with nasotracheal intubation. Methods:40 cases were equally and randomly divided into two groups: sufentanil group (group S) and sufentanil-midazolam group(group S-M).The continuous dose was 2 ml/h. If the patients feel uncomfortable, patient controlled intravenous analgesia (PCIA) was used. To observe the changes of circulation and respiration,the changes of visual analogue scale(VAS) and Ramsay score, the patients' bucking times within 24 h and the PCIA times, patients' total satisfactory degree and the complications during postoperative analgesia were recorded. Results:There were significant decreases in VAS of two groups after postoperative analgesia 1, 4, 12, 24, 48 hours(P

To investigate the expression change of BDNF in lamina II of spinal cord from partial deafferented cats, L6 segmentsof spinal cord from 20 adult male cats (5 normal cats, 15 unilateral L6 spared roots cats allowed to survive 3 d, 6 d and 12 d re-spectively) were stained with immunohistochemical technique. The results showed: BDNF positive products were mainly dis-tributed in nerve terminals, varicosities and few neurons of spinal cord lamina II in normal cat. After operation, the density ofpositive nerve terminals and varicosities began to decrease on the third day, reached the lowest level on the 6th day and recoveredto normal level on the 12th day on operated side. But the number of BDNF neurons showed no obvious change. The authors sug-gest that the decreased density of BDNF positive products in lamina II on the 3rd and 6th day was related with the degenerationof the nerve fibers and varicosities after section of the adjacent dorsal roots. On the 12th day, the remaining L6 dorsal roots un-derwent collateral sprouting compensatoryly and reestablished functional connection with target neurons. Therefore, BDNF maybe involved in the normal physiological function and the plasticity of spinal cord after damage.

Objective To evaluate the resultof applying computer simulated human for the diagnostics teaching.Methods The survey was conducted on medical simulation teaching and traditional teaching applied in 338 medical students through statistical evaluation of operative performance and questionnaire.Results The simulation teaching group performed better than the traditional teaching group on the operative assessment(P<0.05).79.2%students thought it was necessary to have simulation teaching.Conclusions Computer simulated human Can improve students'clinical practice ability.

ObjectiveTo evaluate the result of problem-based learning combined with Casebased learning teaching model in the clinical probation of digestive medicine.MethodsPBL combined CBL teaching method and traditional teaching method were used respectively among 120 medical students who were divided into two groups randomly. Educational effects were evaluated through examination and ques-tionnaire.Results The PBL combined CBL group test scores are significantly higher than traditional teaching group ( P＜0.05 ).96.4％ students thought it was necessary to have PBL combined CBL teaching.ConclusionsPBL combined CBL teaching method is an effective teaching method for medical students.

Objective To investigate the development of ICUs and critical care medicine at secondary and above hospitals in Inner Mongolia.Methods Questionnaire survey of ICUs at secondary and tertiary hospitals in Inner Mongolia Autonomous Region from October 2010 to June 2011.Results There are 76 ICUs at 26 hospitals,including 24 general ICUs and 52 special ICUs; tertiary hospitals average 2.47±0.63 special ICUs,while secondary hospital average 2.23±1.12 special ICUs; 35％ of the ICUs are subject to close-off management; general ICUs at tertiary hospitals account for 1.21％ ± 0.35 ％ of total beds of the hospital,and for 1.98％ ± 0.63％ of secondary hospitals.Regarding the ratio of physicians to ICUs beds,it is 0.75±0.15 at tertiary hospitals,and 0.62± 0.231 at secondary hospitals.As to the ratio of nurses to beds,it is 1.58 ± 0.72 at tertiary hospitals,and 1.36 ± 0.27 at secondary hospitals.Conclusion This survey showed that ICUs in Inner Mongolia Autonomous Region are acceptable in numbers,but are found with problems in insufficient beds,poor staff deployment,obsolete medical equipments and weak technical forces.Therefore,critical care medicine and ICU development should be enhanced during the second round of hospital accreditation in China.
