ABSTRACT

Objective To study on the metal clip installation to avoid post-operative bleeding in pa- tients accepted papilla sphinctecotomy.Methods One hundred and eighty five patients who accepted ERCP +EST were divided into two groups:Group 1 was given routine regimen alone(N=95),group 2,given routine regimen and metal clip to prevent post-operative bleeding.Results The postoperative bleeding hap- pened in 3(3.2%)cases of Group 1 and none in Group 2,there is significant difference between these two groups(P<0.05).The breeding cases in group 1 were controlled by metal clip under endoscopy successful- ly.Conclusion Preventive usage of metal clip was significantly decreased the incidence of post-operative bleeding in EST patients.

ABSTRACT

Objective To study antibiotic resistance phenotypes and genotypes of extended spectrum ?-lactamases (ESBLs) and AmpC ?-lactamase-producing Klebsiella oxytoca isolated from specimens of respiratory tract in children.Methods Bacterial isolates were identified by API or VITEK32. Agar dilution was used for antibiotic susceptibility test,and ESBLs and AmpC were detected by confirmatory test recommended by CLSI/NCCLS and by 3-aminophenylboronic acid (APB) disk potentiation test, respectively.Microarray was used to determine the genotypes of ESBLs and AmpC ?-lactamases.Genotypes of Klebsiella oxytoca were determined by enterobacterial repetitive intergenic consensus (ERIC)- PCR.Results ESBLs were positive in 129 out of 165 isolates (78.2%).Both ESBLs and AmpC ?- lactamases were positive in 16 out of 165 isolates (9.7%).AmpC ?-lactamase alone producer was not detected in term of phenotype and genotype.CTX-M was the most common type of ESBLs and DHA was the only type of AmpC ?-lactamase in these isolates.Most antibiotic resistant strains of Klebsiella oxytoca possessed the same genotype by ERIC-PCR.Although all strains were susceptible to carbpenem,Klebsiella oxytoca with ?-lactamases were more resistant to other antibiotic agents than those without ?- lactamases.Conclusions There is high prevalence of ESBLs production among Klebsiella oxytoca isolated from children in Urumqi.The main genotypes of ESBLs and AmpC ?-lactamases are CTX-M and DHA.
