We should continue to carry out monitoring work, and focus on strengthening health education for pregnant women, and guide them to supplement iodine scientifically and accurately.

Purpose To identify whether serum-free culture can enrich breast cancer stem cells from MCF-7 human breast cancer cell line. Methods MCF-7 human breast cancer cell line by serum-free culture and serum culture technology were cultured, its cell mor-phology and growth pattern were observed by the inverted microscope. The expression of stem cell surface molecular makers CD24, CD44 was observed by the inverted fluorescence microscope and the flow cytometry, the proportion of different subpopulation cells was detected by the flow cytometry. At the same time, difference of the cell cycle was detected by the flow cytometry. Results The cell line cultured by serum-free culture grew in the form of suspended microspheres of different sizes in the medium, but the cell line cul-tured by serum culture grew in the form of monolayer adherent growth. There was no obvious difference in the expression of stem cell surface molecular makers CD44 between the suspended microsphere cells and the adherent cells, but the expression of CD24 in the sus-pended microsphere cells decreased compared to the adherent cells. The proportion of CD44 + /CD24 -/low phenotype cells in the suspen-ded microsphere cells and the adherent cells was (86. 93 ± 0. 53)% and (19. 98 ± 0. 62)%, respectively (P<0. 05), the proportion of CD44 + /CD24 + phenotype cells was (12. 68 ± 0. 59)% and (79. 90 ± 0. 57)%, respectively (P<0. 05). The proportion of mitotic cells in the suspended microsphere cells and the adherent cells was ( 18. 85 ± 2. 26 )% and ( 43. 91 ± 1. 81 )%, respectively ( P<0. 05), the proportion of quiescent cells was (64. 92 ± 2. 07)% and (39. 82 ± 1. 77)%, respectively (P<0. 05). Conclusion CD44 + /CD24 -/low breast cancer stem cells can be effectively enriched by the serum-free culture technology.

Objective To investigate the efficacy of using crude polysaccharides extracted from cultivated Artemisia rupestris L. ( CARCP) in Xinjiang as an immunologic adjuvant for ovalbumin ( OVA) . Methods The mice were subcutaneously immunized twice with OVA vaccine formulated with CARCP. ELISA assay was performed to measure the levels of IgG, IgG1 and IgG2a antibodies. Flow cytometry analy-sis was performed to detect the percentages of different T lymphocyte subsets ( CD3+CD4+ and CD3+CD8+T cells, CD4+CD44+ and CD8+CD44+T cells) in splenocytes as well as the expression of intracellular cyto-kines ( CD4+IFN-γ, CD8+IFN-γ) and CD4+CD25+Foxp3+Treg cells. Results The levels of IgG, IgG1 and IgG2a antibodies in serum, the percentages of CD3+CD4+, CD3+CD8+, CD4+CD44+ and CD8+CD44+T cells as well as the ratio of CD4+/CD8+T lymphocytes increased significantly in mice immunized with OVA in combination with CARCP (P<0. 05). Moreover, CARCP enhanced the expression of CD4+IFN-γand CD8+IFN-γ( P<0. 05 ) , but inhibited the expression of CD 4+CD 2 5+Foxp 3+Treg cells ( P<0. 05 ) . Conclusion As an adjuvant for OVA, CARCP enhanced the humoral and cellular immune responses, especially the T cell immune responses.
