Protein fulfilling the their roles, one of important ways is through protein-protein interaction. In functional genomic era, identifying all of protein-protein interaction in proteome and mapping the protein interactions that have been attracting many scientists' attention , of which large-scale yeast two-hybrid system is one strategy of most widely used. In recent two years, ambitious projects have launched to examine all of the protein-protein interaction in Saccharomyces cer-evisiae using large-scale yeast two-hybrid system. Nevertheless, huge protein network is larger than that we predict and single yeast two-hybrid system cannot solve all the problems, which need be complemented by other wags.

Objective To investigate the effect of CDA-Ⅱ on the cell cycle progression of breast cancer cells.Methods The effects of CDA-Ⅱ on growth curve, cell cycle progression and morphology of breast cancer cell lines MCF-7 and MDA-MB-231 were observed when CDA-Ⅱ and MCF-7 or CDA-Ⅱ and MDA-MB-231 were blended to cultivate in vitro, in comparison with the classical cell differentiation inducer ATRA. Results CDA-Ⅱ decreased the growth speed and inhibit proliferation ability in breast cancer cell lines MCF-7 and MDA-MB-231.It caused G0/G1 phase block of cell cycle and reduced the rate of S phase of breast cancer cells. Conclusion CDA-Ⅱ has remarkable effect of anti-cell-proliferation and can induce cell cycle block of G0/G1 on breast cancer cells. This results provide experimental bases for the treatment of breast cancer with CDA-Ⅱ.

Objective To study the effect of fat emulsion intravenous infusion on serum free fatty acids(FFAs) in rats.Methods 24 male Wistar rats were divided randomly into 3 groups,8 rats in each group.(1)Control group(NS),the rats were infused with normal saline intravenously and regular chow;(2)Group LCT,infused with 10% intralipid fat emulsion intravenously;(3)Group MCT/LCT,infused with 10% lipofundin fat emulsion. Group LCT and group MCT/LCT were continuously received equal calorie,nitrogen and volemin in 'All-in-One'solutions. Serum samples were drawn on the 8th day after PN for fatty acid determination. Results The FFAs in Group LCT and group MCT/LCT were remarkably higher than that in control group, but no difference between Group LCT and group MCT/LCT. Conclusions Fat emulsion intravenous infusion can increase the serum free fatty acids considerately.

Objective To investigate the effect of CDA-II on apoptosis of breast cancer cells. Methods The effects of CDA-II on growth curve, cell apoptosis and morphology of breast carcinoma cell lines MCF-7 and MDA-MB-231 were observed by in vitro cultures, and compared with the classical cell differentiation inducer ATRA. MCF-7 and MDA-MB-231 cell lines have their different biologic characteristics. Results CDA-II can reduce growth and proliferation ability and induce cell apoptosis of breast cancer cell lines( MCF-7 and MDA-MB-231). Conclusions CDA-II has remarkable effect of anti-cell-proliferation and induction of (apoptosis) on breast cancer cells MCF-7 and MDA-MB-231 . Our results provide experimental bases for the treatment of breast carcinoma with CDA-II.

Objective:To explore the value of different MRI sequences in the diagnosis of breast lesions. Methods:Using Philips Achieva 1.5T Nova Dual MRI with SENSE~ breast coil, MRI scanning was performed on 21 patients clinically suspected suffering from breast cancer. MRI sequences included T1WI/TSE,T2WI/TSE (turbo spin echo), short TI inversion recovery(STIR),diffusion weighted whole body imaging with background body signal suppression (DWIBS) and dynamic contrast-enhanced MRI scanning THRIVE. MRI findings were compared with histopathological results. Results:The detection rates of breast lesions of the five sequences were 53.85%, 65.38%, 80.77%, 88.46% and 100%. The sensitivity, specificity and accuracy of dynamic contrast-enhanced MRI scanning were 100%, 77.78%, and 92.31% respectively, which were better than other sequences in the differential diagnosis of the lesions. Conclusion:Dynamic contrast-enhanced MRI scanning could accurately show the numbers of the lesions, describe the morph and size of the lesions and provide more information for the surgeons. DWIBS and STIR could detect the breast lesions more sensitively than T1WI/TSE and T2WI/TSE sequences.

Objective To investigate the feasibility of macrophages as cell carriers to deliver floate modified oxygen loaded ultrasound contrast agent . Methods The phagocytic activity of macrophages was analyzed by ink phagocytose test , and the expression of folate recepters ( FRs ) on macrophages cell membrane surface was tested by immunofluofluorescence assay . Oxygen/paclitaxel loaded lipid microbubbles( OPLMB) and folate‐targeted OPLMB ( TOPLMB) were synthesized by mechanical shock method and incubated with macrophages in vitro . According to different treatment conditions ,the cells were divided into three groups:group A ( OPLMB) ,group B ( free folic acid + TOPLMB) and group C ( TOPLMB) , the fluorescence intensity of the cells were observed under fluorescence microscope ,and the phagocytic percentage and the phagocytic index of macrophages uptake OPLMB and TOPLMB were observed by bright field microscope . Results The phagocytic percentage of macrophages phagocytose ink was (99 .3 ± 1 .0)% ,FRs was highly expressed on macrophages cultured in vitro . After incubation for 30 minutes ,the fluorescence intensity of group C was significantly higher than those of A and B ,the phagocytic percentage in three groups were (19 .5 ± 0 .2)% ,(21 .0 ± 0 .2)% and (81 .2 ± 10 .0)% respetively . The phagocytic percentage of group C were significantly higher than those in group A and group B ( P <0 .05) . Conclusions Macrophages cultured in vitro possess highly phagocytic activity and these cells highly express FRs ,and can be used as cell carriers to deliver floate modified oxygen loaded multimodality ultrasound contrast agent .
