p27kip1 is an important negatively regulator of cell cycle progression and plays a central role in the pathogenesis of a member of tumors including breast cancer. In breast cancer cells, the level of p27kip1 expression usually decreases during tumor development and progression, in addition, cytoplasm mislocalization of p27kip1 has been reported, but less is known about the exact molecular mechanisms. Studies have indicated that phosphorylation is the key regulation way, several signal transduction pathways are involved in the regulation of the expression and distribution of p27kip1. To further understand the mechanism, the disparity of the interacting protein profiling between tumor cells and normal cells must be identified first. Including cyclins, cyclin-depend kinases, CRM1, jab1, SKP2, p27kip1 has various interacting molecules. There are also several interacting molecules especially for breast cancer cells. It seems that different protein profiling cause the different expression and intracellular distribution in different cell cycle phase. So, disparity of the p27kip1 protein profiling may be the main mechanism of its down-expression and mislocalization in breast cancer cells.

[Abstract ] Objective Difficulties with the preparation of gastric cancer stem cells (CSCs) have been a main obstacle to the studies of gastric cancer .This article addresses the technology of the serum-free medium suspension cultivation of the MKN-45 gastric cancer cell line and screening of stem cells from the cell line based on the biomarkers of gastric CSCs . Methods MKN-45 cells were cultured in serum-free medium for 8 weeks and those in the logarithmic phase cultivated with hoechst 33342 followed by detection of the side cells by flow cytometry .When the side population cells reached 25%, all the cell microspheres were collected , hatched with CD133 and CD44, and subjected to fluorescence-activated cell sorting.The CDl33 +and CD44 +cells were selected as gastric CSCs . Results About 40%of the MKN-45 gastric CSCs were alive , prolif-erated, and formed floating cell balls .Side population cells constitu-ted 3.4% of the MKN-45 cells and 26.9% of the cell balls.The CDl33 +and CD44 +cells made up 11.2% of the MKN-45 cells and 90.3%of the cell balls. Conclusion Cell balls rich in CSCs can be successfully obtained by serum-free medium suspension culti-vation and CSCs can be screened out with hoechst 33342 and surface markers , which may serve as an experimental ground for the stud-ies of gastric CSCs .

Objective To investigate the characteristics of distribution and the changes in drug resistance of Enterococci,providing reference for clinical treatment.Methods The distribution and drug resistance in 2547 clinical isolates of Enterococci from 2001 to 2007 in Huzhou Central Hospital and the First People's Hospital of Huzhou were retrospectively analyzed.Results A total of 2547 strains of Enterococci were isolated from 94876 clinical specimens(2.68%),in which Enterococcus faecalis wag primary and Enterococcus faecium Wag ranking the second.The positive rate of Enterococci in urine specimens was the highest,and that in sputum specimens was increasing recently.Enterococci showed higg resistance to erythromycin,rifampin,ciprofloxacin and levofloxacin;Enterococcus faecalis Wag more sensitive to penicillin,ampiciilin and ndtrofurantoin than Enterococcus faecium,while Euterococcus faecium was more sensitive to chloramphended and tetracycline than Enterococcus faecalis;both of them were sensitive to vaneomycin and teicoplanin.Conclusions Enterococcus faecalis and Enterococcus faecium are the common pathogen in Enterococci infections.Enterococci show high drug resistance,so the clinical use of antibiotics should be based on the resuhs of drug sensitivity test.

OBJECTIVE To study the mechanism of drug-resistance of multi-resistant Pseudomonas aeruginosa,and provide the guideline for treatment and control of P.aeruginosa infection in hospital.METHODS Fifty strains of multi-resistant P.aeruginosa were selected with K-B susceptibility method.The three-dimensional method was taken to differentiate the various beta-lactamases.The relative drug-resistance gene was detected by polymerase chain reaction(PCR).RESULTS Among 50 strains of multi-resistant P.aeruginosa,there were 2 strains(4%)producing ESBLs,20 strains(40%)producing AmpC beta-lactamases,and 11 strains(22%) producing ESBLs and AmpC beta-lactamases at the same time.There were 8 positive genes in the detected drug-resistance gene,the most common sources of gene were CTX(56%),OprD(60%) and aac(6′)-Ⅱ(60%),respectively.CONCLUSIONS The main beta-lactamases are AmpC beta-lactamases and the main genotype is CTX in the multi-resistant P.aeruginosa cultured in our area.The main course of imipenem-resistance was deletion of outer membrane proteins,and the aminoglycoside modifying enzyme gene and disinfectant-resistance gene in multi-resistant P.aeruginosa are acquired.In order to reduce the drug-resistance strains and control the infection of P.aeruginosa,antibiotics should be used reasonably according to drug susceptibility testing clinically.
