OBJECTIVE To investigate the clinical characteristics of imipenem-resistant Pseudomonas aeruginosa sepsis in neutropenic hematological malignancy patients. METHODS A retrospective review of the medical records of 3 cases in neutropenic hematological malignancy patients with P.aeruginosa sepsis in June 2008 were taken. RESULTS All they died within 3 days,2 times blood culture results indicated.With imipenem-resistant P.aeruginosa growth. CONCLUSIONS Neutropenic hematological malignancy patients with imipenem-resistant P.aeruginosa sepsis have rapid progress of the disease and high mortality rates,we should step up surveillance.

Objective To explore the factors influencing pneumococcal vaccination uptake among the el-derly people in Guangzhou. Methods A survey by questionnaire was performed among 827 subjects aged 60 years or above and living in Guangzhou for five consecutive years. Chi-square test and multiple logistic regression analysis were applied to identify factors influencing pneumococcal vaccination uptake among the elderly. Results The positive factors for vaccination uptake among the elderly people included age of over 70 years (OR=1.677, 95%CI: 1.156 ~ 2.434), mental workers (OR = 1.837, 95%CI: 1.214 ~ 2.779), education background of over-three-year-course training (OR=1.769, 95%CI:1.039~3.012), and history of chronic diseases (OR=1.659, 95%CI:1.096~2.512) were positively associated with pneumococcal vaccination uptake. Monthly disposable income was not an influencing factor (OR=1.420, 95%CI: 0.895 ~ 2.251). Conclusion Strengthened publicity of pneumo-coccal vaccination among the elderly people and flexible measures tailored to the needs of different groups are rec-ommended in order to improve pneumococcal vaccination uptake among the elderly people.

AIM:To clarify if interferon-?(IFN-?), tumor necrosis factor-?(TNF-?)and interleukin-1?(IL-1?)can induce apoptosis of human airway smooth muscle cells (ASMCs) in vitro. METHODS: Human ASMCs were isolated and cultured in DMEM containing 10% fetal bovine serum. Passage 4-6 cell was used in the experiment. IFN-?,TNF-? and IL-1?, were used separately or together in the treatment of human ASMCs. The effects of IFN-?,TNF-? and IL-1? on the growth of the cells was detected by MTT method at the hour 0,24,48 and 72. Light microscopy and electron microscopy were used to examine the morphological change. DNA fragmentation was analyzed by agarose gel electrophoresis. SP immunohistological staing method was performed to detect the change of expressions of p53 , bcl-2 and bax gene. The apoptosis cell percentage were detected by in situ end labeling technique (TUNEL)of fragmental DNA. RESULTS: (1)IFN-? or IFN-? together with TNF-? and IL-1? decreased the number of viable cells in a time dependent manner. (2) Light and electron microscopic examination showed cell shrinkage, membrane blebbing, nuclear contraction, chromatin condensation and nuclear fragmentation in human ASMCs. (3) Agarose gel electrophoresis showed a characteristic"ladder"of DNA bands representing integer multiples of the internucleosomal fragments (about 180-200 bp) in cytokine cotreated human ASMCs. (4)The expression of p53 and bax gene in cytokine cotreated group was significantly higher than in control group, but the expression of bcl-2 gene was lower than in control group. (5)Stimultaneous treatment with IFN-?(4?10 5 U/L),TNF-?(4?10 5 U/L)and /or IL-1? (10?10 4 U/L) induced apoptosis of human ASMCs. Apoptotic index of human ASMCs in cytokine co-treated group was significantly higher than in control group ( P
