OBJECTIVE To analyze the incidence and relevant factors of hospital infection of newborn baby in a mother with own baby room,to put forward the corresponding nursing countermeasures,as a result,and to probe into the nursing ways for decreasing the incidence of hospital infection of newborn baby in the same conditions.METHODS A retrospective analysis was made on the monitoring material concerning the hospital infection of newborn babies,who were born in our hospital from 2001 to 2005,in a mother with own baby room.RESULTS The average sick rate of hospital infection of newborn baby in the same conditions was 1.12%.Among them,3.10% was in 2001,1.62% in 2002,1.09% in 2003,0.32% in 2004 and 0.05% was in 2005.And the most was respiratory tract infection,in which the key pathogen causing the infection was Staphylococcus epidermidis.CONCLUSIONS In order to decline the sick rate of hospital infection of newborn baby living in a mother with own baby room,room conditions should be carried out by air disinfection,using disinfected nursing articles and simultaneously doing well the respiratory tract nursing and basic nursing.

OBJECTIVE To transfer the dispersing management non-disposable medical instrument packages into the centralized management by the supply department,to improve its quality and save the medical cost.METHODS The centralized management adopted the step by step implementation strategy,standardized recycling,cleaning,and packaging procedure for key instruments.The cleanliness and integrity of the packaging sheet,the in-packet indicator cards and the out-packet label,and instrument and their human and material resources consumption were compared each other.RESULTS Under the centralized management,the cleanliness and integrity of packaging sheet,the wholeness indicator cards in packet and outside packet of instrument label were obviously better than dispersing management(P

Objective:To observe autophagy in human peripheral blood T lymphocyte.Methods:Peripheral blood T lymphocytes of healthy adults were separated with Percoll(1.073 g/ml) and harvested by using nylon column. The cultured cells were divided into control and dexamethasone(DXM) group, and cell morphology was observed through light microscope, electron microscope and fluorescent microscope at 0 and 72 h. And incidence rate of autophagy was analyzed by flow cytometry.Results:①The natural cultured T lymphocytes showed typical morphology of autophagy. ②There was significant statistic difference between 0 and 72 h incidence rate of autophagic T lymphocyte in both control and DXM group. ③There was significant statistic difference in 72 h incidence rate of autophagic T lymphocyte between control and DXM group.Conclusion:Autophagy can be seen in human peripheral blood T lymphocytes, and DXM could induce autophagy.

Objective: To investigate the inspection mode of ethical issues for multicenter clinical trails in China, and to make analysis and give suggestions while taking into consideration of the international conventions. Methods: Representatives from 21 general hospitals and specialized hospitals from Liaoning province, Jiangsu province, Sichuan province, Guangdong province and Shanghai participated in a training course on promotion of ethical review capability; they were surveyed by anonymous questionnaire. Another 20 clinical trial agencies and ethical committees were interviewed by telephone. The questionnaires were collected and valid questionnaires were subjected to statistical analysis. Results: We found that 65.1% of the interviewees never used a central institutional review board (IRB); the main reasons included that they could not assess the quality of central IRB, they wanted to protect the subjects, they had a poor communication with the IRB, and they could not obtain a satisfactorily-localized informed consent forms. There were 34.9% of the interviewees used a central IRB, because they wanted to shorten the inspection time, avoid influence to the research progress, and to have satisfactory quality of IRB. Conclusion: Central IRB is not widely accepted. The related system needs to be further completed so as to improve the outcome of the inspection. The communication and cooperation between the central and local IRBs should be strengthened.

The co-channel interference (collisions) seriously affect the transmission for the newly deployed wireless sensor networks since there is no structure at that phase. In this paper, the interference of the whole network is analyzed based on the SNIR model. The new concept of critical transmitting range is proposed, based on which the transmission theorem is obtained and proved. The results provide the theoretical ground to set up the primary structure of newly deployed networks.

Objective:To optimize the preparation technology of ketoconazole and miconazole nitrateβ-cyclodextrin inclusion com-pound. Methods: The weight ratio of β-cyclodextrin to ketoconazole, inclusion temperature and inclusion time as the testing factors, the optimal inclusion technology was screened by orthogonal experiments. Results:The optimum inclusion conditions were as follows:the weight ratio of β-cyclodextrin to ketoconazole was 8 ∶1, the inclusion temperature was 50℃, and the ultrasonic time was 50 min. Conclusion:The optimized β-cyclodextrin inclusion process is simple and convenient to carry out.
