Objective:To investigate the inhibitory effect of RXRγ and RARβ on the growth of human gastric carcinoma cell line SGC7901 treated by RXR agonist(9-cis-RA). Methods:The human gastric carcinoma cell line SGC7901 was treated with 9-cis-RA, and then the morphological changes were observed by H-E staining. The cell growth was detected by MTT assay. The apoptosis and the cell cycle progression were analyzed by flow cytometry. The expressions of RXRγ and RARβ were detected by immunocytochemistry staining and western-blot assay. Results: HE stain showed that the SGC7901 cells were sparser with the increasing concentration of 9-cis-RA. The growth of SGC7901 cell was inhibited by 9-cis-RA at the concentration of 20 μmol/L in time and dose depended manner. The apoptotic rate of the tumor cells increased after 72 hours at the concentration of 20 μmol/L 9-cis-RA and the tumor cells were arrested in G0/G1 phase. Immunocytochemistry and Western-blot assay showed that the expressions of RXRγ and RARβ increased after 72 hours, compared with those of negative control group. Conclusion: RXR agonist 9-cis-RA can inhibit the growth of SGC7901 cells via inducing cell apoptosis through upgrading the expressions of RXRγ and RARβ.

Objective:To investigate the occurrence of antenatal anxiety and possible influencing factors,and analyze its relationship with spontaneous delivery.Methods: 590 healthy puerperal women who delivered in Taihe hospital during Dec 2007 and Dec 2008 were randomly selected and investigated for their psychological status,with T-A1 anxiety scale and SDS depression scale employed.Results: 569 effective questionnaires were gathered,with 114 cases divided into the anxiety group and 159 cases into the depression group.Influencing factors of antenatal anxiety include fear of delivery,worry about the safety of babies,understanding of delivery knowledge,puerperal age,and the family financial status.Conclusion: Factors including a relatively older age of primipara,poor financial status,insufficient support from family,worry about the safety of oneself and baby,and fear for delivery pain all have close connections with antenatal mental disorders.Meanwhile,antenatal mental disorders have a direct influence on delivery quality and the choice of delivery modes,and increase the failure rate of spontaneous delivery.
