Objective To investigate antimicrobial resistance and pathogen in hebei antibacterial resistance investigation net in 2012.Methods Antimicrobial susceptibility test was detected by Kirby-Bauer method or broth dilution test.Results were analyzed according to CLSI 2010 breakpoints.WHONET 5.5 software was used to analyze the data.Results A total of 10 504 clinical isolates were collected in 2012,of which gram negative bacilli and gram positive cocci accounted for 76.2%, 23.8%,respectively.The most common pathogen in gram-negative rod was E.coli,K.pneumoniae,P.aeruginosa, A.baumanii and E.cloacae respectively.The most common pathogen in gram-positive cocci was S.aureus,E.facium,E-.faecalis,S.pneumoniae and S.epidermidis.ESBL rate of E.coli and K.pneumoniae was 66.5 and 46.7%.The resistant rate of E.coli,K.pneumoniae,E.cloacae to imipenem was 0.1%,0.5%,8.9% and to meropenem was 0.1%,0.6%,4.2%, respectively.P.aeruginosa was resistant to imipenem and meropenem were 38.9% and 32.3%.A.baumanii was resistant to imipenem and meropenem were 5 6.5% and 5 9.7%.Methicillin-resistant strains accounted for an average of 5 7.5% in S.aureus and 87.3% in coagulase negative staphylococcus.Staphylococcus was still susceptible to minocycline and chloram-phenicol.No staphylococcal strains were found resistant to vancomycin,linezolid.But a few coagulase negative staphylococcal strains were resistant to teicoplanin.Conclusion Surveillance of antimicrobial agents played an important role in controlling hospital infection.

Objective To study the sedative and hypnotic effects of Yening Capsules and investigate its bioactive mechanism in mice. Methods The mice were randomly divided into control group, estazolam group （0.8 mg/kg）, low, medium and high-dose Yening Capsules groups （400, 600 and 800 mg/kg）. The locomotor activity, latency to persistent sleep, sleep duration and sleep rate were determined respectively in mice via the open field test and injection of pentobarbital sodium in subthreshold and suprathreshold doses. The content of GABA, 5-HT, DA and NE in brain tissue of mice were detected by enzyme-linked immunosorbent assay（ELISA）. Results Compared with the control group, Yening Capsules medium and high dose group （P<0.05, P<0.01）significantly decreased the locomotor activity of mice.The sleep latency in Yening Capsules medium and high dose group were significantly shorten （P<0.05, P<0.05）and the sleep duration （P<0.05, P<0.01）were extended. The sleep rate of Yening Capsules medium and high dose groups （P<0.05, P<0.01） was significantly increased. Compared with the control group, high dose of Yening Capsules can significantly increase GABA (P<0.05), 5-HT (P<0.05), DA (P<0.05), NE (P<0.01) in mouse brain tissue. Conclusion Yening Capsules had obvious sedative and hypnotic effects, and its mechanism may be related to the increasement of GABA, 5-HT, DA and NE level in brain tissue of mice.
