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.

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.

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 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

Hospital performance evaluation based on lean management is discussed in the paper, which covers all hospital staff by means of appropriate evaluation tools,accurate division of groups to evaluate,precise setting of evaluation indexes,refined relationship between evaluation and remuneration, and strict execution and feedback.This contributed to overall performance betterment of the hospital, and rational performance evaluation and remuneration patterns.

Objective To compare the effect of natural antioxidants TA9001 and EGb761 on c-jun, NOS expression and survival of spinal motoneurons following brachial roots avulsion. Methods One hundred and eighty adult Sprague-Dawley female rats were randomly divided into TA9001, ECb761 and control groups. The right C 5～T 1 nerve roots were avulsed and then the introperitoneal injection of 1ml of 0.5% TA9001, 0.5% EGb761 or normal saline was given immediately and once daily to the rats, respectively. The rats were killed after survival for 4 h, 12 h 1 d,3 d,5 d,and 1 week, 2 weeks, 4 weeks and 6 weeks. The cryostat sections of C 7 segment were prepared and carried with c-jun immunocytochemistry, NADPH-d histochemistry and neutral red counter stain. Results The c-jun and nNOS gene expression was only appeared in injured motoneurons. c-jun was first appeared at 4 h, reached its maximum at 1 d, and grandually decreased till 2 weeks. NOS was first checked at 5 d, mostly at 2 weeks and decreased until 6 weeks. Avulsed motoneuron death started at 2 weeks, reached its peak at 4～6 weeks. Both TA9001 and EGb761 can cause c-jun up-regulation, nNOS down-regulation and more motoneuron survival as compared to control. Furthermore, EGb761 had more power to enhance c-jun expression than TA9901 at each time point. Conclusion It seems that nNOS is more important in motoneuron death mechanism than c-jun. Treatment of either TA9901 or EGb761 can protect the injured motoneurons following root avulsion.

Objective To investigate the relation between the formaldehyde content of newly decorated houses and the time after decoration finished, which will offer an important reference to housing corporations and household. Methods The formaldehyde contents of newly decorated houses in Maoming were analyzed by colorimetry, Mar-Aug, 2003. Results The formaldehyde content in house A, in which the floor was compound floor boards, was higher than that in house B, in which the floor was wearable bricks. The formaldehyde content was not only related to the time after decoration finished, but also to the air temperature. After decoration finished, it must take half a year that the content of formaldehyde would meet the national standard limit. In consecutive testing, it was found that the content of formaldehyde would increase a little as the air temperature increased. Conclusion It must be attached importance to the formaldehyde content in the house floored with compound boards. It will need 6 months at least that the content of formaldehyde meet the requirement of the national standard after the newly house decoration.

Objective To explore proper methods of and environment for people oriented management so as to meet the various new challenges confronting hospitals.

Results An exploration was made into the theories and principles to be followed, the means to be adopted and the human environment to be created in implementing people oriented management. Conclusion Hospitals implementing people oriented management and thus achieving maximized benefits in human resources management will be able to enhance their market shares and maintain sustainable development.
