Drug sensitive test and three-dimensional test220 strains of Pa were isolated from hospitalized patients between 2003 and 2007. K-B method was used to tested the susceptibility of 10 different antibiotics. IRPa was screened by testing the minimal inhibitory concentration of imipemem by using agar diluiion method.The susceptibility of these IRPa to the antibiotics was analysised. Three-dimensional test was used to identify the different kinds of beta lactamases from 220 strains of Pa.2.Carbarpenems hydrolytic enzyme genes and oprD2 gene were detectedamong the selected IRPa strains, PCR method was performed to detect carbapenemase genes which included GES、KPC、SPM、VIM、IMP、GIM gene and the oprD2 gene;Multiplex PCR were used to detect OXA genes and plasmid-mediated AmpC beta lactamase genes; The expression of the chromosomal AmpC beta lactamases and oprD2 genes in IRPa strains were analyzed by Real-time PCR.3.Identification and characterization of integronsIntegrase gene was detected by PCR, and the classification of integrons was performed by using restriction fragment length polymorphism.PCR was performed to detect the qacE△1-sull gene,and the gene cassetes which are located at variable region of integrons in the strains were detected to be positive.

方法1、药敏实验和三维实验收集2003～2007年临床分离的220株Pa，对这些菌株采用K-B法测定10种临床常用抗生素的药敏情况，同时采用琼脂稀释法检测亚胺培南的最低抑菌浓度(Minimal inhibitory concentration，MIC)，筛选出对亚胺培南耐药的铜绿假单胞菌，并分析其对其它抗生素的药物敏感率；采用三维实验的方法分析220株Pa产β内酰胺酶的类型。2、碳青霉烯类水解酶和oprD2蛋白的检测针对鉴定的IRPa菌株，采用普通PCR方法检测具有碳青霉烯水解作用的β内酰胺酶耐药基因(GES、KPC、SPM、VIM、IMP、GIM基因)和oprD2基因，采用多重PCR的方法检测OXA型基因和质粒携带的AmpC酶基因，用荧光定量RT-PCR方法检测oprD2蛋白基因表达情况；同时对产AmpC酶的Pa(25株，含IMP耐药和敏感株)用RT-PCR方法检测AmpC酶基因的表达量情况。3。

The diluent solution of glyoxylic acid and oxalic acid was used as the separation object.TOA (in n-octanol) was used as the solvent. The extraction characteristics of single acid and two-acid solution were studied,and the influence of pH and the concentration of complexing agent on the distribution coefficients were measured. The suitable mathematic models were proposed to describe the relationship between TOA and carboxylic acid based on assumed extraction reaction in organic phase.
