1Magnetic resonance imaging in breast cancer:A literature review and future perspectives显示文摘Early detection and diagnosis of breast cancer are essential for successful treatment. Currently mammography and ultrasound are the basic imaging techniques for the detection and localization of breast tumors. The low sensitivity and specificity of these imaging tools resulted in a demand for new imaging modalities and breast magnetic resonance imaging(MRI) has become increasingly important in the detection and delineation of breast cancer in daily practice. However, the clinical benefits of the use of pre-operative MRI in women with newly diagnosed breast cancer is still a matter of debate. The main additional diagnostic value of MRI relies on specific situations such as detecting multifocal, multicentric or contralateral disease unrecognized on conventional assessment(particularly in patients diagnosed with invasive lobular carcinoma), assessing the response to neoadjuvant chemotherapy, detection of cancer in dense breast tissue, recognition of an occult primary breast cancer in patients presenting with cancer metastasis in axillary lymph nodes, among others. Nevertheless, the development of new MRI technolo-gies such as diffusion-weighted imaging, proton spectroscopy and higher field strength 7.0 T imaging offer a new perspective in providing additional information in breast abnormalities. We conducted an expert literature review on the value of breast MRI in diagnosing and staging breast cancer, as well as the future potentials of new MRI technologies.Gisela LG Menezes Floor M Knuttel Bertine L Stehouwer Ruud M Pijnappel Maurice AAJ van den Bosch 2014World Journal of Clinical Oncology2014,5,2:25
2大别山双河和碧溪岭超高压变质岩流体包裹体研究显示文摘对大别山双河和碧溪岭含柯石英榴辉岩和硬玉石英岩进行了详细的流体包裹体研究。根据流体包裹体的成分和盐度的不同 ,可以划分出至少五种类型不同的气液包裹体 :( 1) N2 包裹体 ;( 2 )高盐度流体包裹体 ;( 3) CO2 包裹体 ;( 4) CO2 -H2 O包裹体 ;( 5 )低盐度流体包裹体。N2 包裹体仅见于含柯石英榴辉岩 ,而高盐度流体包裹体则几乎存在于所有的榴辉岩和硬玉石英岩中。 CO2 包裹体沿榴辉岩中微剪切带分布 ,或存在于强变形的硬玉石英岩中 ,而低盐度流体包裹体分布较为局限。N2 和高盐度流体被认为是超高压变质作用平衡的产物 ,来源于变质前的古孔隙流体。而且榴辉岩中含有一系列盐度不同的流体显微域 ,其大小与矿物颗粒相当。在板块折返过程中 ,包裹体中流体可能发生迁移 ,但是不会超出寄主晶体的范围。CO2流体明显是外来的 ,可能来自共生大理岩或含碳酸盐的变质沉积岩。这与菱镁矿和柯石英等共生组合所指示的进变质过程中大理岩不存在脱碳反应的结论相一致。而低盐度流体则可能系顶峰变质矿物分解而成 。傅斌 肖益林 J L R Touret A M Van den Kerkhof JHoefs 郑永飞 2000岩石学报2000,16,1:14
3改进医疗服务质量、确保病人安全的教学方法显示文摘提高医疗服务质量、确保病人安全是当前医学教育及培训面临的巨大挑战。今天的医生及医务工作者应具备良好的沟通能力,掌握如何在临床实践中鉴别、预防和处理不良事件及接近过失事件(nearmisses),如何使用当前获得的证据及相关信息,如何安全有效地在团队中工作,如何在实践中教授和学习病人安全知识,如何根据认可的伦理原则服务公众。Merrilyn M Walton Bruce H Barraclough Samantha A Van Staalduinen Susan L Elliott 段玉蓉(译) 张鸣明(审校) 2009中国循证医学杂志2009,9,9:7

5TAT-Gap19通过抑制啮齿动物星形胶质细胞的连接蛋白43半通道发挥抗惊厥作用显示文摘越来越多的证据表明,星形胶质细胞连接蛋白43(Cx43)信号在癫痫中发挥至关重要的作用。但是,由于通过实验方法鉴别Cx43间隙连接通道(GJCs)和半通道(HCs)的技术尚不成熟,导致目前尚无法确定哪个通道在癫痫的发生中发挥更重要的作用。因此,本研究观察TAT-Gap19(Cx模拟肽)是否通过抑制Cx43半通道而非Cx43间隙连接通道影响实验诱导的啮齿动物癫痫发作。急性海马切片小鼠染料摄取实验表明,星形胶质Cx43半通道响应化学惊厥毛果芸香碱的作用而开放,并且可被TAT-Gap19抑制。体内实验中,毛果芸香碱诱导的癫痫发作及相伴随的D-丝氨酸微透析液的增长水平被Cx43半通道的抑制所抑制。此外,TAT-Gap19的抗惊厥作用被外源性D-丝氨酸给药逆转,这表明,抑制Cx43半通道可以通过降低细胞外D-丝氨酸水平来防止癫痫发作。抑制Cx43半通道的抗惊厥特性在电癫痫小鼠模型(如急性6 Hz难治性癫痫发作模型和慢性6 Hz角膜点燃模型)中得到了进一步的证实。总而言之,这些结果表明,Cx43半通道在癫痫发作中可以起到一定作用,并且有成为癫痫治疗中新型用药靶点的潜力。Walrave L Pierre A Albertini G Aourz N De Bundel D Van Eeckhaut A Vinken M Giaume C Leybaert L Smolders I 聂昊 2018神经损伤与功能重建2018,13,6:5
