RÉSUMÉ
Objective To study the diagnostic value of combined detection of CEA,CA19-9,CA242 and CA72-4 on colorectal cancer. Methods Serum levels of CEA,CA19-9, CA242, CA72-4 were measured by chemiluminesence immunoassay method in all the patients. Results The results showed that the serum levels of CEA, CA19-9, CA242,CA72-4 content were significantly higher in the colorectal carcinoma group than those in the benign colorectal diseases group(P<0.05),the sensitivity,specificity,availability of united detection serum CEA,CA19-9,CA242,CA72-4 for rectal carcinoma were 81.7%and 95.1%,there was significant difference compared to single detection (P<0.05). Con-clusion United detection of serum CEA,CA19-9,CA242,CA72-4 can improve the sensitivity for the early diagnosis of cancers.
RÉSUMÉ
OBJECTIVE:To observe the effects of clarithromycin and fleroxacin on Pseudomonas aeruginosa(PA) biofilm METHODS:Clinical isolates of 7 strains of PA from respiratory tract were cultured with modified plate culture method;bacterial biofilm model was identified by silver nitrate staining;MICs were determined by broth microdilution The number of viable bacteria in biofilm was measured by using MTT method and bacterial adherence was measured by crystal violet staining RESULTS:1/16MIC and 1/4MIC of clarithromycin could inhibit the adherence of PA to silica-gel film(P
