Tubeimu（TBM）, the rhizome of Bolbostemma paniculatum（Maxim.） Franquet, is one of the Chinese medicinal herbs used for breast diseases since the ancient times. The present study evaluated the efficacy, especially the anti-metastatic effects of the dichloromethane extract of Tubeimu（ETBM） on TNBC orthotopic mouse models and cell lines.Methods： We applied real-time imaging on florescent orthotopic TNBC mice model and tested cell migration and invasion abilities with MDA-MB-231 cell line. Digital gene expression sequencing was performed and Kyoto Encyclopedia of Genes and Genomes（KEGG） analysis applied to explore the pathways influenced by ETBM.Moreover, quantitative real-time polymerase chain reactions（q RT-PCR） and Western blot were delivered to confirm the gene expression changes.Results： ETBM exhibited noticeable control on tumor metastasis and growth of TNBC tumors with no obvious toxicity. In compliance with this, it also showed inhibition of cell migration and invasion in vitro. Its impact on the changed biological behavior in TNBC may be a result of decreased expression of integrin β1（ITGβ1）, integrin β8（ITGβ8） and Rho GTPase activating protein 5（ARHGAP5）, which disabled the focal adhesion pathway and caused change in cell morphology.Conclusions： This study reveals that ETBM has anti-metastatic effects on MDA-MB-231-GFP tumor and may lead to a new therapeutic agent for the integrative treatment of highly invasive TNBC.展开更多

Cephalalgia is associated with an increased risk of developing pregnancy complications or psychological difficulties. Objectives: To investigate the prevalence and the characteristics of maternal cephalalgia during pregnancy and early postpartum and identify associated risk factors. Study Design: This study was conducted between May 2012 and August 2012. The study population comprised 170 mothers. The interviews were conducted in a postnatal ward during the first postpartum week and information on the characteristics of maternal cephalalgia before and during pregnancy was collected. Data regarding previous history of cephalalgia, pregnancy and postpartum health history, as well as the mode of delivery were also recorded. Mothers were given a cephalalgia diary in order to record medication use, as well as cephalalgia attack frequency, severity (5-level scale) and duration. The following surveys were administered: Edinburgh Postnatal Depression Scale (EPDS), Mediterranean Diet Score (Medi Score), International Physical Activity Questionnaire (IPAQ) and Women Abuse Screening Tool (WAST) within the first week postpartum. Statistical analyses were performed using SPSS 19. The level of statistical significance was set at p Results: Maternal self-reported cephalalgia in pregnancy and early postpartum was significantly associated with scores in EPDS (depressive symptoms) (p = 0.005), hypertension (p Conclusion: Pregnancy and early postpartum is a graceful period in women with cephalalgia. However, cephalalgia is associated with an increased risk of developing pregnancy complications or psychological difficulties. Further studies should elucidate the safety and recommended use of cephalalgia medication during pregnancy and breastfeeding.展开更多
