BACKGROUND:Side population(SP)cells,with varied contents,are widely distributed in adult tissues,embryos,and certain tumor cells.Haematological tumor is one of the main pathological conditions,which endangers human life.Thus,it is important to recognize SP cells in haematological tumor cell lines.OBJECTIVE:To identify whether hematologic tumor cell lines contain SP cells,and to explore a stable detection and separation methods.METHODS:Cells with the characteristics of stem cells being capable of fluorescent dye Hoechst33342 were isolated by flow cytometry;whether there were SP cells in logarithmic growth period of NB4,Raji,K562/ADM and K562 or not were detected.After sorting K562 subpopulations,the purity of sorted cells was detected.RESULTS AND CONCLUSION:After Hoechst33342 staining,flow cytometry results showed that the SP cells appeared in the haematological tumor NB4,Raji,K562/ADM and K562 cell lines,which accounted for 0.8%,2.7%,1.3% and 2.7%,respectively.These cells could be blocked by Verapamil.The purity was greater after a second detection of SP and Non SP cells in K562 cells.

Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays an important role in several pathological processes of cardiovascular diseases. In this study, the effects of XCT790, a potent and selective inverse agonist of estrogen-related receptor alpha (ERRalpha), on rat VSMCs proliferation and related signal pathways were investigated. The proliferative activity of VSMCs was determined by CCK-8 assay. The mRNA levels of ERRalpha, PGC-1alpha, OPN and MCAD were assayed by RT-PCR. The protein levels of ERRalpha, ERK2 and p-ERK1/2 were evaluated by Western blotting. ELISA was used to assess the protein expression of VEGF. The results showed that XCT790 (5-20 micromol x L(-1)) inhibited rat VSMCs proliferation, and the expression of ERRalpha and its target genes, as well as p-ERK1/2, were also inhibited. XCT790 inhibited VSMCs proliferation in a dose-dependent manner at the dose range from 5 to 20 micromol x L(-1) and in a time-dependent manner at the dose range from 10 to 20 micromol x L(-1). These findings demonstrate that XCT790 inhibits rat VSMCs proliferation by down-regulating the gene level of ERRalpha and thus inhibiting the ERK signal pathway, suggesting that ERRalpha may be a novel potential target for therapeutic approaches to inhibit VSMCs proliferation, which plays an important role in several cardiovascular diseases.

To obtain the optimal preparation technology of Fang-bing nasal inhalant from components of traditional Chinese medicine by central composite design, with an apparatus containing nasal inhalant that simulated the expiration and inspiration of nose, the dissolution in vitro of different optimized inhalant samples designed through central composite design were investigated. The accumulative release of linalool, borneol, menthol was detected with GC. Response surface methodology was used to optimize the conditions of preparation technology by establishing multiple linear regression and second-order quadratic models. Then, deviation was carried out through comparing the observed and predicted values. It was showed that the coefficient of correlation of second-order quadratic model was high. The related coefficient reached 0.999 3, 0.998 0, 0.944 9, separately. The optimum conditions of preparation technology were as following: 84.39% of alcohol concentration, the weight of starch 1.45 g and the weight of carmellose sodium (CMC-Na for short) 1.22 g. The deviations between observed and predicated values showed -0.36%, 1.52%, 2.40%, separately. In this experiment, the established model can describe the good relation between factors and indexes from preparation technology of Fang-bing nasal inhalant and the outcome of prediction is well. This optimal Fang-bing nasal inhalant was used to study its in vivo effect on model rats deprived from sleep and showed sedative and sleep aiding, which will bring an instruction on inhalants of components from traditional Chinese medicine.
