Promoted and mediated by an ionic liquid-[bmim][BF4], fused pyrans or arylbis（4-hydroxy-6-methyl-2-oxo-2H-pyran-3- yl）methanes were efficiently and selectively prepared from the reaction of aldehyde and 4-hydroxy-6-methyl-2-oxo-pyran with or without acetic anhydride. By using these novel procedures, pyrimidine nucleoside-fused pyran and arylbis（pyranon-3-yl）methane hybrids with potential biological activities were constructed.

对近年来国内已发表的744个辉钼矿Re-Os同位素测年数据进行了汇总,发现所有样品辉钼矿中的Re含量具有混合分布的特征。按照岩性和共生矿物种类对所有数据进行了分类统计分析,结果显示辉钼矿中Re含量（质量分数,下同）与岩性和共生矿物种类存在密切的关系：长英质脉和花岗岩中辉钼矿的Re含量最低,几何平均值分别为7.41×10^-6和7.99×10^-6,多在n×10^-6-n×10^-5;矽卡岩中辉钼矿Re含量中等,几何平均值为58.1×10^-6,多在n×10^-5^-n×10^-4;碳酸岩中辉钼矿Re含量最高,几何平均值为231×10^-6,多在n×10^-4左右。辉钼矿的共生矿物种类影响其Re含量的变化,仅与白钨矿（或黑钨矿）和（或）方铅矿、闪锌矿、自然金和自然银共生时辉钼矿Re含量最低,几何平均值为n×10^-7,多在n×10^-8-n×10^-6;仅与黄铜矿和（或）磁铁矿（或磁黄铁矿）共生时辉钼矿Re含量最高,几何平均值为n×10-4,多在n×10^-5-n×10^-3;同时与黄铜矿（磁铁矿或磁黄铁矿）和白钨矿（或黑钨矿、方铅矿、闪锌矿、自然金和自然银）共生时辉钼矿Re含量处在前两者之间,几何平均值为n×10^-6,多在n×10^-7-n×10^-5。综合分析说明,辉钼矿与白钨矿（或黑钨矿、方铅矿、闪锌矿、自然金和自然银）共生或产在长英质脉和花岗岩中可能促使其Re含量降低,与黄铜矿、黄铁矿和磁铁矿（或磁黄铁矿）共生或产在矽卡岩和碳酸岩中可能促使其Re含量升高,辉钼矿Re含量的级数变化可能与其产出状态（岩性和共生矿物种类）密切相关,以及结合近年来辉钼矿Re含量示踪和其他同位素示踪结果间矛盾的存在,认为辉钼矿Re含量的级数变化似乎不能有效地反映出其成矿物质来源。

目的:探讨在高场强3.0T磁共振中扩张型心肌病(扩心病)的影像学表现及临床诊断价值。方法:选择扩心病患者20例,正常对照组15例,均行心脏磁共振(CMR)、心脏超声、冠状动脉造影检查。CMR主要技术包括心脏形态平扫、心脏功能、心肌活性、心肌灌注成像技术。应用Argus心脏功能软件对所得图像进行分析,测定左心室射血分数(LVEF),其结果与超声测得LVEF对比分析。结果:正常对照组分别运用心脏超声与CMR测左室LVEF,结果差异无统计学意义(P>0.05)。扩心病中19例出现室壁运动异常,表现为左室壁弥漫性运动减弱,心脏超声测20例扩心病患者LVEF为(37.7±16.7)%,CMR测LVEF为(30±11.2)%,结果差异有统计学意义(P<0.05)。扩心病中20例(100.0%)出现心肌延迟强化,表现为左心室心外膜下和(或)中层心肌片状强化,共计136个节段扩心病纤维化多表现为肌壁间弥漫性分布,其中发生部位以基底部及中间部间隔壁最为显著;心肌纤维化程度与心肌灌注呈正比。结论:3.0T的CMR检查可以显示扩心病的病变部位、形态、范围、程度、心功能及心肌灌注情况。综合分析CMR各个序列的结果,可以为心肌病的诊断与鉴别诊断提供影像学依据。

A porous monolithic sol-gel column with the solution of methacryloxypropyltrimethoxysilane in toluene with an acid catalyst was prepared in the presence and absence of sodium dodecyl sulfate. In situ polymerization was carded out by γ-ray irradiation within the capillary. The γ-radiation-initiated synthesis could generate radicals directly on the monomer avoiding use of any initiator. The chromatographic behavior of the capillary monolithic columns were studied in the modes of CEC, p-CEC and low pressure-driven separation, all the tests exhibited reversed-phase character. It provided a viable alternative to either thermally initiated or photo polymerization method for the preparation of monolithic columns.

关键词： Monolithic columns electrochromatography γ-ray irradiation polymerization.
