Objective To separate the side population cells(SP) from breast cancer MCF-7 cell line,and observe its biological characteristics.Methods Flow cytometry and Hcechst 33342 dye efflux assay were used to isolate SP cells and non-SP cells from the MCF-7 cell line of human breast cancer.Tumorigenicity of the two subpopulations was observed by a soft agar cloning method.Results The results of FACS analysis indicated that (6.5 ± 0.4 ) ％of the MCF-7 cells were SP cells;The vitro colony formation rate of SP cells was(38.5 ±9.4)％,and higher than that of non-SP cells ( 8.4 ± 2.6 ) ％ ( t =5.34,P ＜ 0,05 ).Concluslon The SP cells sorted from MCF-7 cell line enriched tunor stem cells,which exhibited high tumorigenicity.It indicated that SP cells should play a principal role in breast cancer.

Background: Xiaochaihu Tang was a compound traditional Chinese herbal medicine recorded in ancient Chinese medical book Shanghanlun, and has been widely used for chronic liver diseases especially in Japan. Objective: To assess the beneficial effects and safety of Xiaochaihu Tang, for chronic hepatitis B (CHB). Search strategy: Electronic and manual searches were conducted and the search ended in November 2009. Inclusion criteria: We included randomized clinical trials testing Xiaochaihu Tang against placebo, non-specific treatment, antivirals, or combined with antivirals against antivirals alone. Data extraction and analysis: Selection of trials for inclusion, assessment of methodological quality by Jadad score, data extraction and data syntheses were conducted according to the Cochrane Hepato-Biliary Group methods. Results: Sixteen randomized trials (involving 1 601 CHB patients) with various methodological quality were included. One trial published in English had good quality, while other trials published in Chinese were of poor quality. The pooled results showed that Xiaochaihu Tang combined with antiviral drugs was more effective in serum loss of hepatitis B viral markers and in improving liver function compared with antiviral drugs alone. Xiaochaihu Tang was not different from placebo in terms of viral clearance or improving liver function. However, Xiaochaihu Tang was superior to non-specific treatment in liver function improvement. There were no adverse effects reported in the trials regarding Xiaochaihu Tang, but adverse effects were reported in patients treated by interferon, and severe adverse effects occurred in few cases. Conclusion: Xiaochaihu Tang in this review appears to be effective in improving liver function and clearance of serum hepatitis B viral markers in patients with chronic hepatitis B. However, due to poor methodological quality in the majority of included trials the potential benefits need to be confirmed in rigorous clinical trials following international standards.

OBJECTIVETo study the effect of Ti-TiO2 nanotubes with different diameters on the adhesion of fibroblast and osteoblast, and to find which diameter was more favorable for cells' respective adhesion.

METHODSPure titanium sheets were polished and then anodized at different potentials for 1 h with Ti as anode and Pt as cathode. TiO2 nanotubes formed at 1, 5, 10 and 20 V potentials served as experimental groups and polished pure titanium served as control group. Field emission scanning electron microscopy (Fe-SEM) was used to analyze the surface topography. Stained nucleus with Hoechst33342 were used to measure the cell adhesion. The cell shape on the sample surface were analyzed with Fe-SEM.

RESULTSTiO2 nanotube array of different inner diameters from 15 nm to 100 nm were grown on titanium sheets by anodization at potentials from 1 to 20 V. At 30, 60 and 120 min, fibroblast adhesion at nanotubes anodized at 5 V was (141 ± 9), (388 ± 14) and (489 ± 15) respectively, significantly less than any other nanotube surface at the same time (P < 0.01). Nanotubes anodized at 20 V had the least inhibitory effect for fibroblast adhesion with a number of (579 ± 14) at 120 min, and the cell shape was also inhibited. At 30, 60 and 120 min, osteoblast had a significant better adhesion on nanotubes formed at 5 V than it did on any other surface at the same time (P < 0.01), except the control group at 30 min, with the adhesion number of (198 ± 10), (431 ± 10) and (501 ± 10) respectively, and osteoblast had a abundant spread on nanotubes formed at 5 V; while osteoblast adhesion on nanotubes anodized at 20 V was (152 ± 11), (403 ± 9) and (465 ± 12) respectively, less than on any other nanotube surface within the same time (P < 0.05), and the cell shape on the surface changed to be more elongate.

CONCLUSIONSFibroblast adhesion is inhabited more or less on Ti-TiO2 nanotubes of different diameters. Nanotubes formed at 5 V have the most osteoblast adhesion, and inhibit fibroblast adhesion.
