The typical aza-BODIPYs in the dye family are known for bright fluorescence,excellent stability,and tunable absorption wavelengths.Hence,these dyes are attracting the increasing attention.Aza-BODIPYs having the maxima absorption in the near-infrared (NIR) region (650-900 nm) are very favorable for bioimaging in vivo due to the less photo-damage,deeper tissue penetration,and less interference from background auto-fluorescence by biomolecules in the living systems.Many strategies have been employed to modify the structures of the aza-BODIPY core to provide the NIR absorbing dyes.Among these,the most effective method is the fusion of the aromatic rings in aza-BODIPY system.This review allsidedly summarizes the recent development of ring-fused aza-BODIPY dyes (λabs ＞ 700 nm) focusing on the design,synthesis,and potential applications in the NIR region since 2002.

随着我国经济的快速发展,推动了医疗保险的普及与覆盖,增加了保险基金的收支结余数值,为了提升保险基金的稳定性与安全性,必须要加强医保基金会计核算和财务管理.但从目前会计核算与财务管理的状况来看,还存在基金筹集不到位、缺乏基金的监管力度等问题,所以必须要意识到会计核算与财务管理的薄弱之处,不断提升医保基金的信息化水平,规范医保基金管理的各项流程,加强对于医保基金的监督与管理,从而提升医保的管理效率与水平.本文对上述等问题进行了深入的研究与分析,提出了合理化的解决措施,以期提供一些思考.
通过“部门预算支出经济分类科目-校内各部门-经费项目”三维的高校教育培养成本项目模型构建,对LL大学的教育培养成本核算进行研究,分析高校成本核算情况下财务会计核算应关注的问题,提出应注重部门预算支出经济分类科目的核算和高校经费项目属性的管理,规范高校成本费用以及费用受益期间的确认依据和核算标准,按照人、财、物使用方向准确划分费用类型等针对高校财务管理特点的财务会计核算优化建议,从而真实、准确地反映高校教育培养成本.
