RESUMO

Objective To verify the detection ability of experimental animal quality detection laboratories in China for Staphylococcus aureus.Methods The testing samples for Staphylococcus aureus detection were prepared by bacterial culture, homogeneity test and stability test, according to the study plan approved by CNAS.Then the samples and operation instruction were sent to the participant laboratories.The detection reports from these laboratories should be submitted before the deadline expires, and the collected data were summarized and analyzed.Results There were 28 laboratories which joined to this test plan.Among them 22 laboratories ( 78.57%) achieved satisfactory test results, and six laboratories (21.43%) had unsatisfactory test results.27 Laboratories used the national standard detection assay, while only one labo-ratory used PCR assay.Conclusions Most of experimental animal quality testing laboratories in China have sufficient pro-ficiency in detection of Staphylococcus aureus.The obtained information are very helpful for the laboratory ability verification testing in future.

RESUMO

Objective To study the expression and clinical significance of anty-apoptosis protein BAG-1 in non-small cell lung cancer(NSCLC),and its relationship with cell apoptosis and expression of Bcl-2 protein. Methods Immunohisto chemistry streptavidin-peroxidase conjugated (SP)method was used to examine the expression of BAG-1protein and Bcl-2 protein,and terminal deoxynucleotidyl transferase mediated UTP nick end labeling(TUNEL) method was used to examine the apoptosis index in 54 cases of NSCLC.The expression of BAG-1 protein in 20 cases of normal bronchus mucosa tissue also be detected as control. Results Express positive rate of BAG-1 protein in NSCLC is 74.07%,obviously higher than that in normal bronchus mucosa tissue(positive rate is 5%).In cases of NSCLC,the expression of BAG-1 protein has not correlation with the age,gender,pathologic classification,but have closed correlation with lymph node metastasis,degree of differentiation,pTNM stage(P
