Objective To investigate the distribution of pathogenic microbes in blood culture and analysis of drug resis-tance of common pathogens in children with acute leukemia.Methods BACTE-FX system made by BD company was applied for the blood culture of children with acute leukemia. API or VITEK-2 Compact bacterial identiifcation system was used for iden-tiifcation of bacteria. Antimicrobial susceptibility testing was performed by disk diffusion method.Results Among 6400 blood culture samples in children with acute leukemia, 713 cases were positive at the rate of 11.1%. Among 655 strains ifrst isolated from the patient, Gram-positive bacteria were 52.5% (344/655) and dominated byStaphylococcus. Strains resistant to vancomy-cin and linezolid were not found. 278 strains (42.5%) were Gram-negative bacteria , andS.marcescens andE.coli were dominat-ed. Gram-negetive bacteria showed high antibacterial activity to imipenem with the sensitive rate of 100%. 33 strains (5%) were fungi.Conclusions Staphylococcus,S.marcescens, and E.coli were the most important bacteria in blood culture of children with acute leukemia. We can offer effective help for clinical treatment with the susceptibility testing.

Objective:Examining the difference in the protein profiling of endometrium between the blastocyst-adhering side and the side without blastocyst adhering,in order to study the asynchrony of blastocysts adhesion between two uteri.Methods:The endometrium with and without blastocyst adhering from the mice pregnant for 5 days were analyzed by two-dimensional gel electrophoresis and imaging analysis.Results:The number of matched protein spots between two gels was up to 82.5%.760 and 720 protein spots with a molecular mass between 14.0～75.4 and isoelectric points (pI)from 4～7 were catalogued from silver-stained gels of the blastocyst-adhering endometrium and the endometrium without blastocyst adhering respectively.At least 60 proteins were up-regulated or down-regulated by over two folds between two groups.Conclusion:the different expression of protein profile may be a cause underlying the the asynchrony of blastocysts adhesion between two uteri.

Objective: To evaluate the operational efficiency of the division-level hospitals of Xinjiang Production and Construction Corps. Methods: Use DEA’s CCR model and BCC model to calculate the overall efficiency, pure technical efficiency and scale efficiency of Xinjiang Production and Construction Corps, and use super-efficiency model to calculate efficiency ranking of the division-level hospitals. Results: In the total pattern, there were 28.6%of the agricultural division hospitals at the stage of constant returns scale;in the medical service model, there were only 14.3% hospitals at that stage. Conclusion: From the results of two models, the technical efficiency has more room for improvement, compared with efficiency scale. The hospital needs to improve the level of health care technique, avoid blind expansion, minimize unnecessary input, strengthen internal meticulous management, and improve the overall operating efficiency of the hospital.

Urinary albumin is a biomarker for kidney damage and is widely applied in clinical practice.With more evidence on urinary albumin, it is also recognized as a risk factor for cardiovascular disease and all-cause mortality.This paper focuses on thecurrent status of pre-analytical, mid-analytical and post-analytical process and discusses the progress in standardization of measurement for urinary albumin and the issues which call for the attention of clinical laboratorian.

To meet the requirements of military medical readiness and to win in informatized war, striding development of Chinese medical equipment has to be performed. This paper presents related guiding ideology, principle, mission, objective and countermeasures.

AIM:To determine the effect of reactive oxygen species on the baroreflex and to investigate the intracellular mechanism responsible for baroreflex dysfunction in the heart failure state.METHODS:In the rat model of cardiomyocytes infarct induced heart failure,baroreflex function was evaluated by measuring the relationship between renal sympathetic nerve activity(RSNA)responses and change of blood pressure by intravenous injection of nitroglycerin and phenylephrine.Alteration in baroreflex function was measured under the different reactive oxygen species(ROS)level induced by intracerebroventricular administration of several chemicals.RESULTS:(1)The range of RSNA response,average slope and maximum gain of baroreflex function curve were(92.2?9.9) mmHg,(0.07%?0.01%)/mmHg and(1.20%?0.10%)/mmHg,respectively,in CHF rats,which were significantly lower than those in sham rats(65.6?7.4) mmHg,(0.13%?0.02%)/mmHg and(3.00%? 0.20%)/mmHg(P

Objective To summarize the modernization of information demand of clinical teaching and management of nursing interns, evaluate the effect of development of the nursing intern teaching management information platform in the clinical effect. Methods Through literature retrieval, inductive method, on the basis of the needs analysis of nursing interns, clinical teachers, Nursing Education Center personnel a total of 41 people were divided into 5 groups with 5-7 people each. Brainstorming method was used to build the initial module and design the questionnaire and the interview outline. The clinical teaching teacher questionnaire was investigated in 101 part and in-depth interviews. Results The recovery of 100 valid questionnaires, the effective questionnaire 99.0%(100/101) and in-depth interviews with 15 excellent clinical teachers, the final 7 first level indices and 55 two level indices; finally running test platform development and 6 months, again the clinical teacher interviews, trial platform had a satisfactory result. Conclusion The nursing intern teaching management information platform is helpful to improve the teaching quality of nursing interns and management efficiency.

Objective To analyze the quantitative change of 18 elements in Culex quinquefasciatus Larvae infected by Lagenidium giganteum (Oomycetes:lagenidiales), and to explore possible mechanism of mosquito-killing by the fungus. Methods. Elements in the mosquito larvae at different developmental stages from infected and non-infected (control) groups were detected with automatic bioassay machine. Results . At the early stage of infection, content of Ca and Cu in the infected group was markedly lower while the content of Co and Cd were higher than the control. In 24 hrs after infection, the content of Ca, Mg, Na, P, Fe, Zn, Cu, Mn and Cr was significantly lower while that of K, Mo, Co, Ni, Al, Cd and Pb were higher than those in non-infected larvae. No marked difference was found for the content of Sr and B between the two groups. In 48 hrs after infection, considerable difference was found in 17 elements between infected and non-infected larvae, with only one exception of Sr. Conclusion . Many elements which play an important role in maintaining the vitality of the mosquito larvae decreased and some of the heavy metal elements accumulated after the infection of Lagenidium giganteum. This might be a part of the killing mechanism to Culex quinquefasciatus larvae.

As the people's life quality improved, more and more attention has been paid to indoor air pollution. The SBS (sick building syndrome) resulting from indoor air pollution has become an unavoidable problem in the modern life. Indoor air pollution has been listed as one of the five most dangerous environmental factors to human health. The present paper mainly analysed the prominent indoor air pollutants such as formaldehyde, radon, ammonia, nitrogen oxides and VOCs, which affect indoor air quality, and also pointed out the research direction and the high lights in this field in future.
