Clinical pharmacological study of cefuroxime was carried out in 8 normal volunteers. The drug obeyed two-compartment model kinetics in serum. The mean peak serum concentrations were 32.14, 89.06 and 63.11 (.is/ml respectively after IM, IV injection and IV infusion of 0.75g cefuroxime. Serum concentrations after IV administration dec re- ased rapidly, the elimination half lives ranged from 1.05-1.48 hours Absorption after IM injection was rapid and complete, the bioava-ilability being 98.89%,The apparent volume of distribution. ranged from 0.34 L/kg to 0.37 L/kg after IM and IV administration which showed that cefuroxime distributed mainly in extracellular fluid.The mean urinary recovery of cefuroxime was more than 90% within 24 hours after the administration of the drug.Based on its pha.rmacokinetic characteristics and antimicrobial activity, a therapeutic regimen is suggested for use in the treatment of various infections.

Objective To investigate the intelligence level and its structure of children with cerebral palsy, and to discuss the effect of degree on them. Methods The intelligence function of 45 children with cerebral palsy was tested by means of Wechsler Intelligence Scale for Children-Chinese Revised ~WISC-CR). The total IQ, verbal IQ, performance IQ and Bannatyne four factors were analyzed and compared among the children grouped on the basis of severity of their dysfunction. Results For children with cerebral palsy, the total IQ ~70.02?(19.50)) was lower than that of the normal children, the ratio of mental deficiency was 55.6%; their verbal IQ was higher than performance IQ ~79.80?18.88 vs 64.24?19.28),P

Aime To study the anti-C. albicans activity of baicablin,and to explore its anti-C.albicans mechanism preliminarily. Method ① The minimum inhibitory concentration (MIC) and the minimum fungicidal concentration(MFC) of baicalin against C.albicans were determined by microdilution method. ② By means of incorporation experiment of isotope-labelled precursor, the incorporation inhibitation rates of [ 3H]-TdR,[ 3H]-UdR,[ 3H]-leucine were measured after treatment with various concentrations of baicalin respectively. Result ① The MIC and MFC of baicalin (above purity 98%) against C albicans(1?107 cfu?L -1) were both 1.0 g?L -1. The MIC and MFC of baicalin (above 98% purity) against C albicans(2.5?107 cfu?L -1) both 2.0 g?L -1. ② The dose of baicalin of 0.5, 1 and 2 MIC could obviously inhibit incorporation of the precursors and there were significant differences among the inhibition rate of three precursors incorporation (P0.05). Conclusion ① Baicalin had strong anti-C albicans activity in vitro. ② Baicalin(above purity 98%) could obviously inhibit incorporation of [ 3H]-TdR, [ 3H]-UdR and [ 3H]-leucine into C albicans and the incorporation inhibition rate of [ 3H]-UdR was highest among them, suggesting that the anti-C albicans mechanism of baicalin may be involved with the inhibition of DNA, RNA and protein synthesis.

Objective To summarize the minimally invasive transthoracic ventricular septal defect (VSD) occlusion operation experience in the clinical application. Methods 142 VSD patients (admitted from August, 2013 to October, 2014) were chosen. All patients were treated with minimally invasive transthoracic device closure under the monitoring of transoesophageal echocardiogram. Results 136 cases received successful closure, and 6 cases still need CPB conventional extracorporeal circulation operation. After follow-up for 3 ~ 12 months for 102 patients, 16 cases remain residual shunt. Conclusion The short-term therapeutic effect of minimally invasive transthoracic device closure of VSD is satisfying. However , the long-term follow-up remains to be studied.

OBJECTIVE To characterize clinical feature,frequency of isolation and antimicrobial susceptibility of bacterial pathogens isolated from patients with healthcare-associated bacterial meningitis(HABM).METHODS We review the charts of all patients in whom the diagnosis was based on(national) diagnostic criteria of healthcare-(associated) infections at Huashan Hospital from 1995 through 2004.The pathogens were routinely isolated,(identified) and susceptibilities against antimicrobial agents were determined by Kirby-Bauer methods.RESULTS During the 10-year study period,109 patients were treated for 120 episodes of HABM.Most of patients had a(history) of recent and remote neurosurgery.Fever was present in all patients,while nuchal rigidity and decrease consciousness were present in less than half of all patients.CSF opening(pressure,) white blood cell count and(protein) were elevated with predominance of neutrophils.A total of 120 strains were isolated from CSF specimen,Gram-positive bacteria and Gram-negative bacilli were accounted for 35.8% and(64.2%) of all isolates,respectively.Acinetobacter spp(24.2%),coagulase-negative staphylococci(22.5%),Klebsiella pneumoniae(12.5%),Pseudomonas aeruginosa(10%),Enterobacter cloacae(8.3%) and Staphylococcus aureas(7.5%) were the 6 most frequent isolates and resistance to the first line antibiotics was common among all pathogens isolated.(CONCLUSIONS) The most common risk factor for HABM is neurosurgery.Gram-negative bacilli and staphylococci are important causes of HABM,resistance to the first line antibiotics is common among all pathogens isolated.

20 antimicrobial agents were determined by Kirby-Bauer methods by the participating institutions.RESULTS A total of 428 strains were isolated,Gram-positive cocci and Gram-negative bacilli accounted for 49.8% and 50.2%,respectively.The Gram-positive bacteria increased from 44.6% to 51.2% from 1995-1996 through 2003-2004 and Gram negative bacteria decreased from 55.4% to 48.2% in the meantime.The most frequent Gram-positive isolates were coagulase negative staphylococci,Staphylococcus aureus,Enterococcus spp and Streptococcus pneumoniae;the most frequent Gram-negative isolates were Acinetobacter spp,Klebsiella spp,Escherichia coli,Pseudomonas aeruginosa and Enterobacter spp;Neisseria meningitidis,Haemophilus influenzae,Flavobacterium spp and Citrobacter spp were relative less common.No strains resistant to vancomycin were found in staphylococci and enterococci.Gram-negative bacilli were highly susceptible to carbapenem.CONCLUSIONS Gram-positive cocci play an increasing role in central nervous sysytem infections,especilly coagulase negative staphylococci,and Gram-positive cocci have been increasing from 1995-1996 through 2003-2004,resistance to the first line antibiotics is common among all cerebrospinal fluids isolates.

OBJECTIVE To investigate the trend of resistance of antimicrobial agents among clinical isolates of Klebsiella pneumoniae 1996-2005.METHODS Agar diffusion test was used to analyze the changes in drug susceptibility of K.pneumoniae isolated from 11 hospitals in Shanghai to antimicrobial agents.RESULTS The resistance rates of K.pneumoniae to antimicrobial agents mostly increased 1996-2005.The resistance rates to piperacillin,cefazolin and cefuroxime remained at high levels(more than 50%),while which to cefotaxime(29.3-45.2%) and piperacillin/tazobactam(5.1-20.6%) were increased obviously.Carbapenems were the most active agents against the K.pneumoniae isolates.The resistance rates to ciprofloxacin increased from 14.4% to 35.8%.The detectable rate of extended-spectrum beta-lactamases-producing strains in K.pneumoniae increased from 30.1% to 42.0%.CONCLUSIONS The trend of resistance of K.pneumoniae to commonly used antimicrobials was upward 1996-2005.

Objective To detect the clinical pathogenic bacteria and antimicrobial-resistant genes quickly and sensitively using DNA chip.Methods Based on the analysis of 23S rRNA gene se- quences and other genes sequences associated with antimicrobial resistance(SHV＜CTX_M),oligo nucleotide microarray was designed according to different bacteria and antimicrobial-resistant genes. The DNA fragments were amplified by labeling Cy5 fluorescence and detect clinical pathogenic bacte- rias and antimicrobial-resistant genes by hybridization.Results The result of detection(10~3-10~6 bac- teria/ml)was consistent with that of some documents in domestic and overseas under ideal circum- stances of detecting bacteria genomic DNA by the Reagent Box.And it was specific and reproducible when the detection system were evaluated with some clinical isolates and drug-resistant standard strain.DNA chip could identify 16 species and 7 generics including common diverse clinical pathogenic bacteria,and could detect the drug-resistant of extended spectrum?lactamase gene simultaneously. Conclusions The methods that we have established DNA chip is a sensitive,specific and reproducable tool for supplying routine methods.
