Objective To analyze the antimicrobial resistance and the profile of pathogens from lower respiratory tract infections in pediatric in patients. Methods Sputum bacterial isolates were identified by an automated biochemical identification system. Antimicrobial resistance was detected by an automated drug susceptibility detection system and the disc diffusion method. The β-lactamases was tested by the nitrocefin disc detection method. Results Five hundred and eighteen bacterial pathogens were isolated from sputum samples during 2011-2015, including streptococcus pneumoniae(21.62%), staphylococcus aureus(16.99%), haemophillus influenzae(14.48%), klebsiella pneumoniae(11.97%), escherichia coli(8.11%), moraxelle catarrhalis(3.8%), acinetobacter baumanii(3.86%) and pseudomonas aeruginosa(3.86%). High resistant rates were detected for S. pneumoniae to clindamycin(90.18%), erythromycin(92.86%) and sulfamethoxazole (85.50%), while S. aureus was highly resistant to penicillin G(90.91%) and erythromycin(68.18%). Resistance to vancomycin and linezolid was not detected for gram positive cocci. The resistant rate to ampicillin was 32% for H. influenzae, which was in concordance with the production of β-lactamases. Relatively high resistance was detected for K. pneumoniae and E. coli to cephalosporins and quinolones. A carbapenem-resistant K. pneumoniae isolate was also detected. Conclusion Multiple bacterial species were isolated from lower respiratory tract infections in our hospital, including different species of gram positive cocci and gram negative bacilli, and these isolates exhibited high resistance to antibiotics tested. The clinical use of antibiotics and hospital infection and transmission of these pathogens should be controlled.

Objective The aim of this study was to explore induction and differentiation of endogenous neural stem cells(ENSCs) in the hippocampus soluble factors(HSF) from the hippocampus of adult Wistar rats by mimicking an intracranial microenvironment. Methods After Wistar rats sacrificed, the hippocampus tissue was obtained in cold DMEM/F12. After centrigued and filtered, the HSF was stored at -20℃. The ENSCs was obtained from the hippocampus tissue of a neonate Wistar rat. Collected the tissue, digested and obtained the ENSCs. After we observed the morphology, the ENSCs were cultured in different concentration (0、50、100、200、400 μl/mL) of HSF for 6 days, and compared the expression of Nestin and CD133 by immunocytochemistry. Meanwhile,we compared the Nestin and CD133 protein by western blot. And then we explored the optimal concentration of HSF by the numbers of all groups on the second and sixth day. Furthermore, we did the differentiated experiment using the same concentration of HSF. Results The number of neurospheres in the 100 μg/mL group was significantly higher than those in the other groups on the 6th day. Immunofluorescence revealed that the neurospheres from ENSCs in the 100 μg/mL group more highly expressed nestin and CD133 than control. This result was confirmed by western blot analysis. The neurospheres can differentiate into glia-like cells in 100 μg/mL HSF and 1% FBS expressing GFAP, S100 and P75 NGFR by immunofluorescence. Conclusion These data indicated that HSF alone, mimicking a destination of ENSCs in vitro, could induce and differentiate neurospheres from ENSCs, as a new method to get NSCs and glia-like cells differentiated from ENCs to repair the diseases of center nervous system.
