ABSTRACT
Objective The clinical distribution and drug resistance of isolated Acinetobacter Bauman strains were retrospectively analyzed in Xiangya Hospital Central South University in 2015,and its resistant transitions in ten years were also analyzed,to provide theoretical guidance for clinical rational use of antibiotics and control of infection.Methods 534 Acinetobacter Bauman strains were collected at Xiangya Hospital in 2015,the clinical distribution characteristics and drug resistance of Acinetobacter Bauman strains were analyzed according to specimen type,department,age and drug resistance result.Meanwhile,the drug resistance situation was compared with that in 2006 and 2011.Results The isolation rate of Acinetobacer Bauman from respiratory tract specimen was 76.78％,the tolal isolation rate from ICU,respiratory department of internal medicine,neurology department of internal medicine and neurosurgery department ward was 57.87 ％,and the infection patients over the age of 61 occupied 37.83 ％.Risperidone/Shubatan showed the best antibiotic activity with the resistance rate 3.02 ％ in ten drugs,the Acinetobacter Bauman strains were resist to other nine drugs in different level,with the percent from 50.0％ to 85.0％.The drugs of tobramycin and imipenem showed the greatest growth,with the resistance rate of 1.87％ and 11.70％ in 2006 in Xiangya hospital,increased to 69.85％ and 80.53％ in 2015,respectively.The drug of levofloxacin and cefepime also showed great growth in ten years with the increase of 58.81％ and 55.98％,respectively.Conclusion The clinical isolates of Acinetobacter Bauman strains mainly derived from respiratory tract specimen,and mainly distributed in ICU,the most infection people were from the older.The resistance rate of common drugs showed a significant increase in ten years,especially for cephalosporins and carbapenems.With the increase of multiple drug resistant strains,the monitoring of drug resistance of Acinetobacter Bauman and use of antibiotics rationally should be strengthened.
ABSTRACT
Objective To detect the clinical value of measuring glycosaminoglycan sulfate segments to the diagnosis of non small cell lung carcinoma(NSCLC).Methods Using the new regent manufactured by the USA POLY labs,LTA emulsion regent,we have measured the distinctive glycosaminoglycan sulfate of the 30 NSCLC serums and 30 normal serums and 26 pneumonia serums.Result The method of using LTA emulsion regent to measure content of the distinctive glycosamingoglycan sulfate had the peculiar quality of 90% and the sensitive quality of 83 33% in NSCLC.The CEA's sensitive quality was 56 67% in the same sample.The unite sensitive quality of LTA and CEA was 93 33%.The pneumonia had no significant effect on the LTA's peculiar quality.Conclusion LTA emulsion regent has higher peculiar and sensitive qualities to the diagnosis of NSCLC by measuring the content of glycosaminoglycan sulfate,combined with CEA,the sensitive quality can be improved and make the diagnosis more accurate.It is quite valuable to the clinical diagnosis.And the prospect is wide in applying to the clinical general investigations.
