Objective To investigate the effect of cerebrospinal lfuid replacement combined with vancomycin and dexamethasone intrathecal therapy on biochemical indicators of postoperative intracranial infection, in order to improve the clinical diagnosis and treatment. Methods 70 cases with intracranial infection collected in Third Hospital of Beijing Armed Police Corps from February 2010 to April 2013 were as subject, and randomly divided into two groups. Control group(n=35) were given cerebrospinal lfuid replacement and ceftriaxone intravenously, observation group(n=35) were given cerebrospinal lfuid replacement combined with vancomycin and dexamethasone intrathecal injection. The clinical effects and biochemical indicators were observed after treatment in two groups. Results In control group, the cure rate was 22.86%and total efifciency was 77.14%. In observation group, the cure rate was 37.14% and total efficiency was 91.43%. The differences between two groups were statistically significant (P<0.05). The differences of leukocytes, glucose, protein, intracranial pressure in two groups after treatment were also statistically signiifcant(P<0.05). Conclusion Cerebrospinal lfuid replacement combined with vancomycin and dexamethasone intrathecal injection therapy can increase intracranial infection.

Objective To express the recombinant protein VP1-Z, and investigate whether VLP-Z has the physiological functions like as wild-type VLP. Methods The expression plasmid pET15b-VP1-Z was introduced into competent E. coil BL21 (DF3)/pLys cells by transformation, and the expression of re-combinant protein VP1-Z was induced by incubation of the cells with IPTG. The protein was prepared as pre-viously described for wild-type VLP. The morphous of VLP-Z were observed by electron microscopy, and the physiological functions of VLP-Z were investigated by hemagglutination test and by immunofluorescence. Re-sults The purified VLP-Z composed of VP1-Z possessed hemagglutination activity and yielded a prominent band of 50×10~3 on SDS-PAGE and staining with Coomassie Brilliant Blue. The VLP-Z exhibited virus-like particles structure like as wild-type VLP with a diameter of 45-50 nm, which was slightly bigger than that of wild-type VLP(42-45 nm). In immunofluorescence test, VP1-Z was detected within the cytoplasm and nu-cleus after HeLa cells were inoculated with VLP-Z. Conclusion The physiological functions of recombinat-ed protein VLP-Z were comparable with wild-type VLP.

Objective To construct the vector pET15b-Z-VP1 by inserting the Z fragment into amino-terminal of JCV VP1.Methods The VP1 and Z fragment were amplified by PCR from plasmid pET15b and pEZZ18 respectively,and then they were linked by recombinant PCR.The Z-VP1 fragment was inserted into plasmid pET15b by restriction enzyme BamHⅠ and NcoⅠ.Results The VP1 and Z fragment were obtained by PCR and gel purification.The Z-VP1 fragment,which was linked by recombinant PCR from VP1 and Z fragment,was inserted into plasmid pET15b between BamHⅠ and NcoⅠ sites,and confirmed by enzyme digestion and DNA sequencing.The expression of VP1-Z was confirmed by Western blotting.Conclusion The plasmid pET15b-Z-VP1 has been constructed successfully by inserting Z fragment into amino-terminal of VP1.
