1.Study on Antimicrobial Resistance of Moraxella Catarrhalis in the Nasopharyngeal Secretions of Children with Respiratory Infection
Journal of Applied Clinical Pediatrics 1994;0(04):-
Objective To explore the antimicrobial resistance of Moraxella Catarrhalis in children with respiratory infection.Methods Eleven strains of Moraxella Catarrhalis were isolated from nasopharyngeal secretion in 145 children with community-acquired respiratory tract infection in Beijing Friendship Hospital from 2004 to 2006.Segregated stocks were isolated from upper respiratory infection in 5 cases,bronchitis in 3 cases and pneumonia in 3 cases.Agar dilution method was used to determine minimal inhibition concentrations (MIC),including 8 kinds of antibiotics,and ?-lactamase was detected.WHONET 5 and SPSS 11.5 software were used to analyze data.Results Ten of the 11 strains were ?-lactamase positive.The rates of resistance to ampicillin,cefuroxime and erythromycin were 81.8%,63.6% and 18.2% respectively,however,all the strains were susceptible to ceftriaxone.MIC90 of penicillin and cefradine was 32.0 mg/L and 8.0 mg/L respectively.MIC90 of roxithromycin and azithromycin was 2.0 mg/L and 0.25 mg/L respectively.Conclusions Moraxella Catarrhalis is an opportunistic pathogen.The ?-lactamase positive rate of Moraxella Catarrhalis from children is high,and there is also a high resistance percen-tages of Moraxella Catarrhalis to penicillin,ampicillin,first and second generation cephalosporins.Moraxella Catarrhalis is susceptible to Cefuroxime.

Objective To investigate antirnierobial resistance of comlnon pathogenic bacteria isolated from children's respiratory tract in Beijng friendship Hospital during the period between January 2004 and December 2006.Methods Forty-nine strains of Streptococcus pneumoniae,fifty-five strains of Staphylococcus aureus and fifteen strains of Group A β-hemolytic streptococcus were isolated from children with community-acquired respiratory tract infeetion in pediatric department of Beijng Friendship Hospital.Kirby-Bauer agar dilution method Was used to determine the susceptibility to antimicrobial agents.Results Ninety percent of Streptococcus pneumoniae strains were resistant to erythromycin.Penicillin-non-susceptible streptococcus pneumoniae accounted for 10%,while 90% of which were multi-drug resistant.For Staphylococcus aureu strains,the resistant rates of ampicillin,penicillin and oxacfllin were 86%,82%,and 9% respectively,and serere multi-drug resistance was found.Eighty percent of the group A β-hemolytic streptococcus strains were resistant to erythromycin,however all remained sensitive to penicillin and ampicillin.Conclusion The antimicrobials resistant pathogenic bacteria isolated from children with respiratory tract infection have become a severe prdblem.The resistant rates of macrolides are high for Streptococcus and Group A β-hemolytic streptococcus.MeticiUin resistant staphylococcus aureus(MRSA)strains were found in the study.Severe multi-drug resistance was found.Non β-lactam antibiotics should be avoided when respiratory tract bacterial infection occurred in children.

Objective To investigate the characteristics and possibility of using an image analyzer-aided method to count axotomized retinal ganglion cells (RGCs). Methods The left optic nerves of 18 rats were transected intraorbitally and a piece of gelform soaked in 5% fluorogold was applied to the ocular stump to retrogradely label the surviving RGCs. All animals were executed 2, 7 or 14 days after the operation (n=6 for each time point), respectively. The left retinae were removed, post-fixed and whole-mounted on the slides. The numbers of labeled RGCs were counted using both the conventional sampling method and image analysis, and compared statistically between the two methods. Results The number of surviving RGCs decreased sharply [(12 0663?9 089), (59 285?17 071) and (17 802?19 84) cells/mm 2 for image analyzer-aided method, and (118 237?7 898), (57 648?14 533) and (18 070?1 461) cells/mm 2 for conventional sampling method] when the survival time increased from 2 to 7 and 14 days. No significant difference was detected between the two groups at any corresponding time points. Conclusion The image analyzer-aided method is convenient, objective and reproducible, which can be used in the studies where counting RGCs is needed.

The implementation of cancer genome scientific program has promoted the diagnosis, prevention and tar-get treatment of diseases at molecular level with massive cancer genome data accumulated. Effective mining and use of cancer genome data have thus become the focus in the field of cancer genome. The cancer genome was annotated and demonstrated according to the mining of high-throughput cancer genome data from American National Cancer Research Center, namely the disease-named entity and drug-named entity were identified from the gene function descriptive text and the mined high-throughput data were annotated from their clinical application, in order to help scientific workers to find the relationship between diseases, drugs and genes in scientific literature.
