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.

ObjectiveTo study streptococcus pneumonia capsular polysaccharide antibodies of patients with chronic obstructive pulmonary disease(COPD) in acute exacerbation and the feasibility of vaccination for patients with COPD.MethodsThe COPD in acute exacerbation without respiratory failure (RF)(COPD without RF group),COPD in acute exacerbation with RF (COPD with RF group),asthma (asthma group),healthy elderly examination(elderly examination group) and healthy youth examination (youth examination group) were selected,and each group had 15 cases.The levels of streptococcus pneumonia capsular polysaccharide antibodies IgG,IgM and IgA were measured in all groups.Results There was no significant difference in IgG among the five groups (P ＞ 0.05 ).The levels of IgM in COPD without RF group and elderly examination group were significantly lower than those in COPD with RF group,asthma group and youth examination group (0.554 ± 0.309 and 0.538 ± 0.327 vs.0.810 ± 0.387,0.887 ± 0.278 and 0.852 ± 0.305,P ＜ 0.05 ).Although the level of IgA in COPD without RF group was significantly lower than that in youth examination group(0.532 ±0.297 vs.0.930 ±0.502,P ＜0.05),there was no significant difference among the five groups.Conclusion Patients with COPD should inoculate pneumococcal vaccination.

Objective:To study the morphology and function of the dendritic cells(DC) from human peripheral blood monocytes and the change in cell differentiation and maturation after DC treated with dexamethasone(Dex-DC).Methods:DCs were sorted from human monocytes by culturing in presence of cytokines(GM-CSF, IL-4) and LPS for 8 days with or without dexamethasone. The change in morphology, function and phenotypic characterization was compared.Results:The cells treated with or without Dex, developed a characteristic dendritic morphology, however, Dex-DC expressed higher level of CD14 and lower level of CD83 than the untreated cells. In addition, a low APC function was demonstrated by Dex-DC.Conclusion:DCs can be induced from peripheral blood monocytes in medium with cytokines; the cultured PS in presence of Dex are shown at a more immature stage, indicating that Dex modulates DC differentiation, maturation, and function.

Objective To study the clinical value of preoperative superselective embolization of nasopharyngeal angiofibroma.Methods 14 patients with nasopharyngeal angiofibroma diagnosed by CT and MRI,and proved surgically and pathologically were included in this study.Angiography of bilateral external carotid artery and internal carotid artery as well as vertebral artery was performed in all cases. The external carotid arterial blood supply of tumors were superselectively embolized with 100～300 ?m particles of gelfoam or polyvinyl alcohol(PVA). Surgical resection was performed post-embolization 1 to 3 days. Results The main feeding vessels of tumors were the internal maxillary artery in 9 patients,the internal maxillary artery and ascending pharyngeal artery in 4 patients,the internal maxillary artery,ascending pharyngeal artery and the branches of internal carotid artery in one patient. Preoperative endovascular embolization of the branches of external carotid artery with microcatheter was achieved in all patients. After embolization,tumor stains disappeared completely in 8 patients and partially in 6 patients. The rate of total resection was 92.8%(13/14).The mean amount of haemorrhage during operation was 420 ml and the mean operation duration was 150 min.No major complications were relevant to embolization occurred.Conclusion Preoperative intravascular embolization of nasopharyngeal angiofibroma with microcatheter is a safe and effective method.
