OBJECTIVE To study the carbapenemase genotypes among Acinetobacter calcoaceticus isolates infected after liver transplantation. METHODS The 5.4 software was used to analyze the resistance of Acinetobacter species. Eight strains of imipenem-resistant A. calcoaceticus which were resistant to multiple drugs were collected. Analytical isoelectric focusing electrophoresis was used to measure the pI of the ?-lactamase. The homology of the isolates was determined by pulsed field gel electrophoresis(PFGE). blaTEM, blaSHV, blaIMP, blaVIM, blaOXA Genes for resistant isolates were amplified and sequenced. RESULTS Imipenem-resistant A. calcoaceticus infected after liver transplantation was resistant to multiple drugs. All of 8 strains were produced OXA-23 carbapenemases (pI of 6.7). The results of PFGE indicated there was a trend of resistant clone transmisstion in the transplantation ward. CONCLUSIONS There is a transmisstion of A. calcoaceticus producing OXA-23 carbapenemase in the transplantation ward of our hospital. It is important to monitor powerfully the bacterial resistance to control infection more effectively.

Objective:To explore the effects of infant sleep patterns on maternal sleep quality.Methods:Three hundred and nineteen pairs of mothers and infants from two grade three class-a hospitals in Nantong City were enrolled. Infant sleep patterns were assessed by the Brief Infant Sleep Questionnaire (BISQ). Maternal sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI). The effect of infant sleep patterns on maternal sleep quality was analyzed by one-way ANOVA followed with multivariate analysis.Results:The maternal sleep quality scored 7.08±2.60. Single factor analysis pointed out that the sleep quality of women whose infants slept in bed near parents, woke up more than 3 times a night, was nocturnal wakefulness more than 60 minutes or nocturnal sleep duration less than 8 hours was significantly worse. After controlling for confounding variables, the way of baby falling asleep, numbers of night wakings, nocturnal sleep duration, maternal age, infant′s gender and primary caregiver were independent factors of maternal sleep quality.Conclusion:Infant sleep pattern is an important factor affecting maternal sleep quality. Nurses should provide information about the sleep patterns of infants to mothers and their family members to promote their babies′ sleep habits so as to improve the maternal sleep quality.

HSP90, which is the biomarker of cell stress and endogenous protective protein, functions as a molecular chaperone. Many client proteins of HSP90, including EGFR, Met, Raf-1, IKK and p53, play important roles in the occurrence and development of tumor. Binding of HSP90 inhibitors triggers the deactivation of HSP90, resulting in client protein degradation, and hence inhibits the tumor growth by blocking multiple targets involved in signaling of tumor proliferation. This review summarizes recent development of small molecule inhibitors bound to N-terminal of HSP90.

In order to research the biologic activity of osteoblast-stimulating factor 1 (OSF-1), the pPIC9K/osf-1 yeast expression vector was constructed to express and purify OSF-1. Firstly, the osf-1 gene sequence was obtained by artificial synthesis and cloned into Pichia pastoris expression vector pPIC9K to generate pPIC9K/osf-1. The recombinant plasmid was linearized by Sac I and transformed into P. pastoris GS115 by electroporation. Recombinant P. pastoris GS115/ pPIC9K/osf-1 was screened by MD and G418-YPD plates and further identified by PCR. The positive P. pastoris was induced with 1% methanol at 25 degrees C for 96 h. The target protein was analyzed by SDS-PAGE showing a special band about 18 kDa. The target protein was successfully purified from the supernatant of the broth using ion exchange chromatography of SP-Sephadex C-50. The purity of target protein was above 98%. Western blotting appeared a good antigenicity of the purified protein. Bioassay results show that the recombinant protein OSF-1 can promote the differentiation and proliferation of osteoblasts MC3T3-E1. We successfully expressed OSF-1 by recombinant P. pastoris for further development of anti-osteoporosis of research and industrial production of OSF-1.
