Fe (III) 2,9,16,23 tertracarboxy phthalocyanine (Fe (III) taPc) was synthesized, and bonded to polystyrene (PS) with covalence by Friedel Crafts reaction to form a new polymer (Fe (III) taPc PS) (polymer (II)). UV VIS and Infrared spectra indicated that Fe (III) taPc was successfully bonded to PS. A photoreceptor device of sandwich structure consisting of alternate layers of polymer (II) and fullerene (C 60 ) was prepared. The experiment results show that the photoconductivity of the photoreceptor is higher than that of the single layer film of polymer (II) or C 60 , because of the charge transfer effect between the layers.

非转移性黑色素瘤糖蛋白b(glycoprotein non-metastatic melanoma protein b,GPNMB)及其同系物色素细胞特异性黑色素细胞蛋白(pigment cell-specific melanocyte protein,PMEL)对黑素体的形成和黑色素的生成具有重要的作用,而GPNMB和PMEL的功能还有待深入研究。本文旨在探索GPNMB和PMEL在不同毛色绵羊皮肤表达是否存在差异,确定紫外线b(UVB)对GPNMB和PMEL是否有影响。免疫组织化学结果表明,GPNMB在不同毛色绵羊皮肤的毛基质、内外毛根鞘、毛乳头等区域均有表达。Western印迹和qRT-PCR结果显示,黑色绵羊皮肤中GPNMB和PMEL表达量,高于白色绵羊皮肤。黑色素细胞经UVB照射后,GPNMB和PMEL的表达增高。UVB照射剂量为100 m J/cm2时,黑色素细胞活性最高;单次UVB辐射后,GPNMB和PMEL mRNA表达量在72h达到顶峰,两者的曲线变化趋势大致相同。UVB连续辐射后,GPNMB mRNA表达量在4 d达到顶峰,而PMEL mRNA表达量虽然在3 d升高,但且对GPNMB作用更明显。上述结果提示,GPNMB和PMEL在不同毛色绵羊皮肤存在差异性表达。UVB单次或者连续照射,均促进GPNMB和PMEL表达,且对GPNMB影响更显著。GPNMB和PMEL可能通过影响黑素体的成熟进而调节黑色素的生成。

子宫内膜容受性(ER)是指子宫内膜允许胚胎黏附和侵入并诱导内膜间质发生一系列变化,最终植入内膜的一种状态。子宫内膜腔上皮可作为寻找ER标志物的切入点。胞饮突是目前最有临床价值的ER形态学指标,然而将其作为ER标志物仍存在争议。蛋白质组学和子宫内膜功能测试(EFT)是目前评估ER的新方法。通过采取多种方法来改善ER,可以有助于提高妊娠率。

A new selective Zn^2＋ fluorescent chemosensor, o-vanillin-4-ethoxybenzoylhydrazone （1）, was designed and prepared. Free 1 mainly displayed very weak fluorescence at 480 nm upon excitation at 403 nm. It displayed high selectivity for Zn^2＋ and had a 518- fold fluorescent enhancement upon binding of Zn^2＋, while the other cation ions had only little influence on the fluorescence of 1. Mechanism of enhancement of l＇s fluorescence by Zn^2＋ was briefly discussed.

Dear editor,Boerhaave’s syndrome is a barogenic tear of the esophagus,typically at the gastroesophageal junction,caused by a sudden increase in intraluminal pressure in the distal esophagus.[1]In recent years,the number of Boerhaave’s syndrome cases has increased,and a growing proportion of clinicians have recognized this rare but life-threatening disease.
