Objective:To establish a new method to detect Amp C?-lactamase by PCR. Methods:The amp C and amp D gene fragments of E. cloacae were amplified by the amp C and amp D primers to detect Amp C ?-lactamase, especially the enduring and highly productive enzymes. Results:Totally 193 of 214 strains of E. cloacae were positive for amp C gene , implicating most strains of E. cloacae had the ability to produce the enzyme. Sixteen of the 193 strains (amp C positive) were negative for amp D genes, implicating these 16 strains could produce the enduring and highly productive enzymes. The results were confirmed by cefoxitin three-dimensional test. Conclusion:The new method to detect Amp C ?-lactamase, especially the enduring and highly productive enzymes,by amp C and amp D primers is a rapid and accurate method.

To study performance problems found in China's essential medicine system.The SmithModel of system implementation was called into play in a systematic collation and analysis for the ideal policies,system implementation agencies,target groups and policy environment in its performance,along with relationships among the four factors.The system is found with a number of loopholes as the system itself is highly idealized,its system objectives set inappropriately,problems found with the four factors,and tension and conflicts among these factors.Given these problems found in its performance,it is inappropriate to make drastic changes to avoid instability of the system at its early stage.Government departments in question are advised to comprehensively analyze the four factors and their relationships then taking effective measures to deal with them and the tension,conflict among them.This can ensure effectively implementation of the essential medicine system.

Objective To explore the association of ATP-binding cassette (ABC) efflux pump gene Rv1217c-Rv1218c and the drug resistance of Mycobacterium tuberculosis.Methods A total of 34 Mycobacterium tuberculosis clinical isolates including 24 drug-resistance isolates which were resistant to riffampicin,isoniazid,streptomycin or ethambutol and resistant to at least one second-line antituberculosis drug,and 10 drug-sensitive isolates were involved in this study.The RNA of isolated strains was extracted and then reverse transcribed. Gene expression was performed by real-time polymerase chain reaction (PCR) and data was analyzed by t test and Logistic regression analysis.Results The expressions of Rv1217c in rifampicin-resistant group (2.13 ± 1.89,t =3.44,P<0.01),isoniazid-resistant group ( 1.84 ± 1.86,t =3.16,P< 0.05),streptomycin-resistant group ( 1.86 ±1.96,t=2.78,P<0.05) and ethambutol-resistant groups (3.36±2.35,t=3.04,P<0.05) were all higher than sensitive isolates (0.42 ± 0.31).The expressions of Rv1218c in rifampicin-resistant group (2.54±1.84,t=3.82,P<0.01),isoniazid-resistant group (2.34± 1.84,t=3.72,P<0.01),streptomycin-resistant group (2.15±1.86,t=3.01,P<0.01) and ethambutol-resistant groups (3.78± 1.78,t=4.22,P<0.01 ) were all higher than sensitive isolates (0.65 ± 0.42).The expressions of Rv1217c and Rv1218c in multidrug resistant group were 2.74±2.07 and 3.33± 1.77,respectively,which were both higher than polydrug resistant group (0.79 ± 0.47 and 1.03 ± 0.79,respectively; t =2.91,P<0.05 ; t =3.84,P<0.01,respectively).Logistic regression analysis found that high Rv1217c expression was positively correlated with rifampicin resistance and negatively correlated with isoniazid resistance (both P< 0.01 ),while high Rv1218c expression was negatively correlated with rifampicin resistance and positively correlated with isoniazid resistance (both P<0.01 ).High expressions of two genes were both positively correlated with ethambutol resistance and multidrug resistance (both P<0.01 ) and not statistically correlated with streptomycin resistance (P>0.05).Conclusions The expressions of ABC efflux pump gene,Rv1217c-Rv1218c,are correlated with multiple drug resistance.The overexpression may contribute to the multidrug resistance of Mycobacterium tuberculosis.

Objective To assess the feasibility and efficacy of Amplatzer duct occluder Ⅱ (ADOⅡ) in occlusion of aortopulmonary collateral arteries. Methods Seven patients,6 males and 1 female, with aortopulmonary collateral circulation diagnosed previously by cardiac Computed Tomograpy or cardioangiography from Mar 2014 to Apr 2015 were enrolled. All of them were treated with ADO Ⅱ. Results The age of the patients ranged between 5 - 71 months old and weight 4. 2 - 22. 0 kg. Successful hybrid approach was achieved in 6 of 7 patients. One patient failed the occlusion because of severe hypoxemia and mild-moderate residual shunt after catheter intervention. Total 15 aortopulmonary collateral vessels were embolized by 7 ADO-Ⅱ, 22 non-detachable coils ( Cook corp. ) and 2 detachable micro-coils ( Boston Scientific corp. ). Complete embolization was achieved in 2 patients,4 patients had mild residual shunt and 1 patient had mild-moderate residual shunt after the embolisation. No interventional complications recorded. Conclusions ADO Ⅱ has high controllability and suitable for application through small delivery catheter for minimally-invasive procedures to the vessels. It is a preferable alternative in treating pediatric patients with large and tortuous aortopulmonary collateral arteries.
