背景在心脏手术中可以通过自体血回收来避免输注同种异体血。另外已有人提出，血液中的碎片可能会增加卒中或神经意识功能障碍的风险，因此，清除回收血中的碎片可改善患者的预后。在此研究中，我们试图通过系统性回顾已发表的随机控制性试验进行荟萃分析，明确在心脏手术中自体血回收的整体安全性和有效性。方法全面检索找出关于所有有关心脏手术中应用自体血回收技术的所有随机试验。截止到2008年11月的MEDLINE、Cochrane图书馆、EMBASE和摘要资料库均被检索完全。将所有心脏手术中应用自体血回收技术与未应用自体血回收技术进行比较，并且报道至少一个明确的临床结果的随机试验均被列为研究对象。随机效应模型被用来依次计算比值比（OR，95％可信区间）、二分法加权平均差（WMD，95％可信区间）和连续变量。结果包括2282例患者在内的31个随机试验最终被作为研究对象进行荟萃分析。在心脏手术中，进行手术中自体血回收减少了接触同种异体异基因血制品（比值比0．63，95％可信区间：0．43—0．94，P=0．02）及红细胞（比值比0．60，95％可信区间：0．39—0．92，P=0．02）的概率，也降低了平均每例患者输注同种异体异基因血制品的总量（加权平均差-256ml，95％可信区间：-416--95ml，P=0．002）。但在以下几个方面进行自体血回收组与未进行自体血回收组之间并无差异，包括：院内死亡率（比值比0．65，95％可信区间：0．25—1．68，P=0．37）、手术后卒中或短暂缺血性发作（比值比0．59，95％可信区间：0．20～1．76，P=0．34）、房颤（比值比0．92，95％可信区间：0．69—1．23，P=0．56）、肾功能衰竭（比值比0．86，95％可信区间：0．41—1．80，P=0．70）、感染（比值比1．25，95％可信区间：0．75—2．10，P=0．39）、接受新鲜冰冻血浆治疗（比值比1．16，95％可信区间：0．82—1．66，P=0．40）以及接受血小板输注治疗（比值比0．90，95％可信区间：0．63—1．28，P=0．55）。结论现有的证据表明应用自体血回收技术可减少心脏手术中患者异体血制品或红细胞的输注。进一步的分析认为，只有在收集失血和（或）剩余机血，或在整个手术过程中应用自体血回收技术才是有利的。如果只在体外循环期间用自体血回收技术作为心内吸引，则对于血液保护没有明显效应且增加新鲜冰冻血浆的输注。

Chirality, which describes the broken mirror symmetry in geometric structures, exists macroscopically in our daily life as well as microscopically down to molecular levels. Correspondingly, chiral molecules interact differently with circularly polarized light exhibiting opposite handedness(left-handed and right-handed). However, the interaction between chiral molecules and chiral light is very weak. In contrast, artificial chiral plasmonic structures can generate "super-chiral" plasmonic near-field, leading to enhanced chiral light-matter(or chiroptical) interactions. The "super-chiral" near-field presents different amplitude and phase under opposite handedness incidence, which can be utilized to engineer linear and nonlinear chiroptical interactions. Specifically,in the interaction between quantum emitters and chiral plasmonic structures, the chiral hot spots can favour the emission with a specific handedness. This article reviews the state-of-the-art research on the design, fabrication and chiroptical response of different chiral plasmonic nanostructures or metasurfaces. This review also discusses enhanced chiral light-matter interactions that are essential for applications like chirality sensing, chiral selective light emitting and harvesting. In the final part, the review ends with a perspective on future directions of chiral plasmonics.

We report holographic fabrication of nanoporous distributed Bragg reflector(DBR) films with periodic nanoscale porosity via a single-prism conuration. The nanoporous DBR films result from the phase separation in a material recipe, which consists of a polymerizable acrylate monomer and nonreactive volatile solvent. By changing the interfering angle of two laser beams, we achieve the nanoporous DBR films with highly reflective red,green, and blue colors. The reflection band of the nanoporous DBR films can be tuned by further filling different liquids into the pores inside the films, resulting in the color change accordingly. Experimental results show that such kinds of nanoporous DBR films could be potentially useful for many applications, such as color filters and refractive index sensors.
