Objective To investigate the therapy and influencing factors for prognosis of ventilator-associated pneumonia(VAP) caused by multidrug-resistant organisms(MDROs).Methods 169 patients with VAP who were admitted to a hospital between January 2012 and December 2013 were included in analysis, 125 were in MDRO infection group and 44 in non-MDRO infection group.MDRO infection group was subdivided into MDR-A group(n=78, resistant to selected antimicrobial agents) and MDR-B group (n=47, sensitive to at least one kind of selected antimicrobial agent).Antimicrobial choice and prognosis between each group were analyzed and compared.Results 242 strains of pathogenic bacteria were isolated from airway secretion of VAP patients, 173(71.49％) were MDROs.The major pathogens causing VAP were Klebsiella spp.(n=66), Pseudomonas aeruginosa(n=64), Acinetobacter spp.(n=60), Staphylococcus aureus(n=27), and Escherichia coli (n=17), the percentages of MDROs of above pathogens were 68.18％, 50.00％, 91.67％, 88.89％, and 76.47％ respectively.The prognosis of MDRO infection group was poorer than that of non-MDRO infection group, MDR-A group had the worst prognosis(P<0.001).Persistent fever, leukocytosis, and progress of pulmonary inflammation in VAP patients suggested poor prognosis(all P<0.001);antimicrobial use in patients with effective therapy was higher than those in a worsened condition before onset, at the beginning of onset, and after culture of specimens(all P<0.001), while coma, early-onset VAP and multiple bacterial infection had no prognostic significance in patients with VAP(all P>0.05).Conclusion There is high incidence of MDRO infection in patients with VAP, effective antimicrobial therapy can improve the prognosis.

OBJECTIVE: Embryonic stem cells (ES cells) is a special kind of cell population with totipotency and uninhibited self-renewal property. Researches on induced differentiation of ES cells were received and summed up to provide reasonable and constructive suggestions for clinical application of ES cells.DATA SOURCE: Papers published in Highwire press and Medline database were retrieved with keywords "Embryonic stem cell, differentiation, and induce" from 2000 to 2004. Additionally, papers published in Wanfang database were also retrieved with keywords "Embryonic stem cell" in Chinese from 2000 to 2004.STUDY SELECTION: Data were analyzed firstly in order to select papers related to induced differentiation. The inclusion criteria were selection of the original works, but the summaries and Meta analysis were excluded.DATA EXTRACTION: A total of 369 papers were chosen according to correlation with keywords; among them, 364 papers were in foreign language. After reading through summaries of these papers, 15 papers thoroughly discussing induced differentiation of ES cells were chosen for further intensive reading. Papers discussed various kinds of differential models, neural cells, cardiac muscle cells, epithelial cells and hematopoietic cells.DATA SYNTHESIS: The induced differential models of neural cells, cardiac muscle cells, epithelial cells and hematopoietic cells from ES cells were introduced comprehensively in the seven literatures. Based on these references mentioned above and other references which introduced cell model separately, all data were generally studied, sorted out and summed up.CONCLUSION: ES cells can be induced to be various kinds of cell models such as neural cells, epithelial cells, cardiac muscle cells and hematopoietic cells, which may be used to clarify the mechanism of cellular development and differentiation to provide good respects for clinical cellular therapy and screening of medicines.

Objective To observe the effect of Puerarin on the level of tau phosphorylation in the olfactory bulb of Alzheimer's disease rat brain, and explore the underlying molecular mechanism.Methods ① Twenty-two male SD rats were randomly divided into the normal control group, model control group and Puerain-treated group.The levels of tau-1, PS396 and tau-5 in the olfactory bulb were detected by Western blotting.② Twenty male SD rats were randomly divided into model control group, low-dose Puerarin (40 mg·kg-1·d-1), medium-dose puerarin (80 mg·kg-1·d-1) and high-dose puerarin (160 mg·kg-1·d-1) groups.The levels of tau-1 and PS396 phosphorylation in the olfactory bulb were detected by Western blotting.③ The level of GSK-3β phosphorylation in the olfactory bulb of the normal control group, model control group A and puerain-treated group was detected by Western blotting.Results ① It was shown by Western blotting that the relative expression of tau-1 was significantly decreased in the olfactory bulb of the model group A(0.49±0.07)rat brain compared with the normal control group(0.85±0.03)(P<0.01), and the level of tau-1 was obviously higher in the puerarin-treated group(0.58±0.03)compared with that of the model group A(P<0.05).The differences of the levels of tau-5 and PS396 in the olfactory bulb were insignificant among the 3 groups.②Compared with the model group B, the expression of tau-1 in the olfactory bulb was significantly enhanced in the low-, medium-and high-dose of puerarin group: (0.39±0.09)vs(0.69±0.11),(0.55±0.11),(0.70±0.04);and the level of PS396 was significantly decreased in the olfactory bulb of low-dose puerarin group(0.36±0.07) compared with the model group B(0.55±0.05)(P<0.01).③Compared with the normal control group(0.96±0.07), the ratio of pS9-GSK-3β/tGSK-3β was obviously decreased in the olfactory bulb of the model group A(0.51±0.12),while that was significantly increased in the puerarin group(0.62±0.03) compared with the model group A(P<0.01).Conclusion Puerarin can attenuate AD-like tau hyperphosphorylation in the olfactory bulb of Alzheimer's disease rat brains, and decreased activity of GSK-3β might be involved in the effects of puerarin on tau hyperphosphorylation.

Objective: Vascular dilation dysfunction has been linked with risk of cardiovascular disease. This study was undertaken to investigate the relationship between physical activity and vascular dilation function in healthy middle-aged adults to help explaining the effect of physical activity on preventing cardiovascular disease. Method: We recruited 91 healthy middle-aged adults to complete a serf-report 7-day physical activity recall questionnaire and an exam of brachial artery flow-mediated dilation(FMD) and Nitroglycerin-mediated dilation (NMD) detected by ultrasound. The relationship between physical activity level (PAL) and FMD and NMD were explored. Result: Physical activity showed a significant and positive relationship with the brachial artery FMD, even after adjustment for possible confounding factors (r=0.363, P<0.01). The group of high physical activity level had the highest FMD. The means of FMD (%) in low, moderate and high PAL groups were respectively 8.70%±3.93%,9.01%±3.22% and 12.38±5.67% with significant difference between individuals of low and high PAL and between moderate and high PAL group(P<0.01). The means of NMD (%) is 25.13%±6.52%,24.38%±5.44% and 29.50%±7.25% respectively (P> 0.05) and there was no significant difference among three groups. There was no positive relation between PAL and FMD in premenopausal females but in men and postmenopausal females. Although individuals of high PAL have the best FMD, the moderate PAL can also retard FMD decrease with ageing. Conclusion: Maintaining high physical activity level can enhance endothelial-dependent vascular dilation, and moderate or high physical activity level can prevent endothelial-dependent vaseular dilation declining with aging, which may contribute to decrease risk of cardiovascular disease in healthy middle-aged adults.
