Academic Journal of Xi'an Jiaotong University 2003;15(2):157-161
The air flow ratio and the pulverized-coal mass flux ratio between the rich and lean sides are the key parameters of horizontal bias burner. In order to realize high combustion efficiency, excellent stability of ignition, low NOx emission and safe operation, six principal demands are presented on the selection of key parameters. An analytical model is established on the basis of the demands, the fundamentals of combustion and the operation results. An improved horizontal bias burner is also presented and applied. The experiment and numerical simulation results show the improved horizontal bias burner can realize proper key parameters, lower NOx emission, high combustion efficiency and excellent performance of part load operation without oil support. It also can reduce the circumfluence and low velocity zone existing at the downstream sections of vanes, and avoid the burnout of the lean primary-air nozzle and the jam in the lean primary-air channel. The operation and test results verify the reasonableness and feasibility of the analytical model.

Objective To investigate the effects of somatostatin (SST) on levels of IL-6,IL-8 and TNF-αduring CPB in pigs. Methods Twenty four healthy pigs were randomly divided into control group (SS00) and 3 experimental groups, SS05, SS10 and SS20. All pigs were performed by CPB for cardiac arrest in 45 min. the levels of IL-6, IL-10 and TNF-αwere tested and compared. Results The TNF-α, IL-6 and IL-10 levels were higher than T0 among all groups after CPB(P<0.05);The levels of TNF-αand IL-6 after CPB in SS10, SS20 groups were lower than SS00 group(P<0.05), and the IL-10 level was higher(P<0.05). Conclusion Infusing with a certain dose of SST before CPB could down-regulate acute inflammatory response;SST has no impact on the operative safety.

Objective To evaluate the etiological and clinical characteristics of fungemia in Peking Union Medical College Hospital.Methods Microbial and clinical information of patients with fungemia consulted in Peking Union Medical College Hospital during 2008 to 2010 were retrospectively analyzed.Results A total of 70 patients were diagnosed with fungemia,and 100% of them had underlying diseases or potential risk factors.Of them,40 (57.1%) patients were monomicrobial fungemia,and the other 30 (42.9%) patients with positive blood cultures were caused by at least two different microbes during hospitalization.Among 122 strains of microbes isolated from blood cultures,72 were fungi and 50 were bacteria.Among the isolated fungi,61 (84.7%) were Candida species,31 (50.8%) were Candida albicans and 30 (49.2%) were non-albicans.According to the colonization or infected sites other than blood of the isolated fungi,35 cases (50.0%) were primary fungemia; 18(25.7%) were colonizing at lower respiratory tract simultaneously; 10 (14.3 %) caused central-line related fungemia; 3 (4.3%) were secondary to intraabdominal fungal infection; and another 4 (5.7%) isolates had multiple colonization sites.During hospitalization,37 cases died with a crude mortality rate of 52.9%,and 22 (32.9%) died of fungemia itself.In single factor analysis,ICU hospitalization(x2 =15.136,P < 0.001),operation history within 30 days (x2 =3.540,P =0.060) and invasive mechanical ventilation (x2 =4.450,P =0.035) were related to crude mortality.Bacteremia during hospitalization (x2 =5.657,P =0.017),circulatory underlying diseases (x2 =3.399,P =0.065) and ICU treatment (x2 =4.955,P =0.026) increased attributable mortality.In the multivariate analysis,ICU history increased mortality during hospitalization,however,the operation history within 30 days was independently irrelevant to crude mortality during hospitalization.ICU history and bacteremia during hospitalization were independently correlated to attribution mortality of the patients with fungemia.Conclusions Fungemia,usually accompanied with bacteremia,occurs often in the patients with underlying diseases.Patients with fungemia have poor prognosis and more than 50% patients die.ICU history increases the risk both to crude and attributable mortality.The patients with fungemia who had polymicrobial bloodstream infection have a higher attribution mortality.Operation history within 30 days is independently negatively correlated to attributable mortality.
