目的虽然自体脂肪移植在面部软组织缺损重建中的应用呈增长的趋势，但在移植前对所获取脂肪的最佳处理方法仍没有达成一致。所有报道的脂肪移植处理技术中，将简单过滤和洗涤的脂肪与使用纯离心脂肪的临床效果进行对比。方法自2006年1月至2006年6月，选取25例即将接受面部脂肪移植的患者进行一项前瞻性的双盲研究。在同一患者的面部，一半注入经过简单过滤和洗涤的脂肪，而另一半注入经过离心的脂肪。用主观和客观的方法对结果进行评估。主观的方法即给所有的患者发一份调查问卷和一封解释信；客观方法即由一个3人组成的评审团对患者术前和术后的照片进行评估。平均随访12个月。结果本研究表明，两种脂肪处理技术无显著性差异。长期随访发现，注入面部的两种脂肪临床效果类似。结论作者从已报道数据中获得了个人经验，在应用了数年离心脂肪后，重新回归到使用简单过滤的脂肪。

In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to Observatory Science targets. These include flaring stars, supernova remnants, accreting white dwarfs, low and high mass X-ray binaries, radio quiet and radio loud active galactic nuclei, tidal disruption events, and gamma-ray bursts. eXTP will be excellently suited to study one common aspect of these objects: their often transient nature. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in the mid 2020s.

背景胰管置管胰液外引流曾被建议使用在胰十二指肠切除术中,以减少术后胰漏的发生率。目的比较行胰十二指肠切除术且胰腺高风险的患者置管胰液外引流和未置管引流的预后。方法:回顾性评价前瞻性获得的数据。2000－2008年间有598位行胰十二指肠切除术的患者;其中有186位(32.7%)存在残余胰腺高风险(胰管≤3mm,胰腺质软)。当中93例行胰管置管外引流(使用5-8号导尿管),另93例未置管。外引流的选择根据手术医生的个人喜好。主要评价指标为胰漏的发生率和严重性(根据国际胰漏定义研究小组对胰漏的定义)。结果:置管组平均胰管直径为2.12mm,而未置管组平均胰管直径为2.49mm(P<0.01)。胰漏发生率在置管组较高(P<0.01):置管组胰漏的发生率为59.1%(A级63.6%;[第一段]

本研究通过外凝胶交联法制备了含有ungeremine (CTUn)的壳聚糖(C)三聚磷酸酯(T)亚微粒子,这种生物碱对造成烘焙产品变质的青霉菌尤其有效。制备了热塑性淀粉基聚合物材料(MBi),并获得了MBi/CTUn生物活性复合材料。结果表明,该膜具有一定的生物活性。特别是对不同浓度的CTUn和不同p H值的膜进行了生物测定。CTUn颗粒影响MBi结晶(DSC分析),促进了MBi淀粉组分(TGA)的热降解。形态分析证实了亚微粒子在聚合物基体中的均匀分布。如预期的那样,水的渗透性略有增加,而氧的渗透性却降低了。拉伸试验表明,CTUn亚微粒子改善了膜的刚度和拉伸强度,但牺牲了延性。最后,MBi/CTUn生物复合材料在生物活性烘焙食品包装材料中具有很好的开发潜力。
