1Carbon Nanotubes in Biology and Medicine:In vitro and in vivo Detection,Imaging and Drug Delivery显示文摘Carbon nanotubes exhibit many unique intrinsic physical and chemical properties and have been intensively explored for biological and biomedical applications in the past few years.In this comprehensive review,we summarize the main results from our and other groups in this field and clarify that surface functionalization is critical to the behavior of carbon nanotubes in biological systems.Ultrasensitive detection of biological species with carbon nanotubes can be realized after surface passivation to inhibit the non-specific binding of biomolecules on the hydrophobic nanotube surface.Electrical nanosensors based on nanotubes provide a label-free approach to biological detection.Surface-enhanced Raman spectroscopy of carbon nanotubes opens up a method of protein microarray with detection sensitivity down to 1 fmol/L.In vitro and in vivo toxicity studies reveal that highly water soluble and serum stable nanotubes are biocompatible,nontoxic,and potentially useful for biomedical applications.In vivo biodistributions vary with the functionalization and possibly also size of nanotubes,with a tendency to accumulate in the reticuloendothelial system(RES),including the liver and spleen,after intravenous administration.If well functionalized,nanotubes may be excreted mainly through the biliary pathway in feces.Carbon nanotube-based drug delivery has shown promise in various In vitro and in vivo experiments including delivery of small interfering RNA(siRNA),paclitaxel and doxorubicin.Moreover,single-walled carbon nanotubes with various interesting intrinsic optical properties have been used as novel photoluminescence,Raman,and photoacoustic contrast agents for imaging of cells and animals.Further multidisciplinary explorations in this field may bring new opportunities in the realm of biomedicine.Zhuang Liu Scott Tabakman Kevin Welsher Hongjie Dai 2009Nano Research2009,2,2:50
2High Performance In Vivo Near-IR (>1 μm) Imaging and Photothermal Cancer Therapy with Carbon Nanotubes显示文摘Short single-walled carbon nanotubes(SWNTs)functionalized by PEGylated phospholipids are biologically non-toxic and long-circulating nanomaterials with intrinsic near infrared photoluminescence(NIR PL),characteristic Raman spectra,and strong optical absorbance in the near infrared(NIR).This work demonstrates the first dual application of intravenously injected SWNTs as photoluminescent agents for in vivo tumor imaging in the 1.0-1.4μm emission region and as NIR absorbers and heaters at 808 nm for photothermal tumor elimination at the lowest injected dose(70μg of SWNT/mouse,equivalent to 3.6 mg/kg)and laser irradiation power(0.6 W/cm2)reported to date.Ex vivo resonance Raman imaging revealed the SWNT distribution within tumors at a high spatial resolution.Complete tumor elimination was achieved for large numbers of photothermally treated mice without any toxic side effects after more than six months post-treatment.Further,side-by-side experiments were carried out to compare the performance of SWNTs and gold nanorods(AuNRs)at an injected dose of 700μg of AuNR/mouse(equivalent to 35 mg/kg)in NIR photothermal ablation of tumors in vivo.Highly effective tumor elimination with SWNTs was achieved at 10 times lower injected doses and lower irradiation powers than for AuNRs.These results suggest there are significant benefits of utilizing the intrinsic properties of biocompatible SWNTs for combined cancer imaging and therapy.Joshua T.Robinson Kevin Welsher Scott M.Tabakman Sarah P.Sherlock Hailiang Wang Richard Luong Hongjie Dai 2010Nano Research2010,3,11:20
32018年急性缺血性卒中患者早期管理指南美国心脏协会/美国卒中协会为医疗专业人员制定的指南显示文摘背景和目的本指南旨在在单个文件中为治疗成年急性动脉性缺血性卒中患者的临床医生提供最新全面的系列推荐意见。目标读者为院前急救人员、医生、综合医疗保健人员和医院管理人员。本指南将取代2013年版指南及其后续更新。方法写作组成员由美国心脏协会卒中委员会的科学声明监督委员任命,代表各领域的医学专家。严格遵循美国心脏协会的利益冲突原则。不允许写作组成员对存在企业利益关系的相关议题进行讨论或投票。所有推荐意见必须得到写作组成员的一致通过,除非企业利益关系妨碍了成员投票。由4名同行评议专家以及卒中委员会的科学声明监督委员会和领导委员会成员对指南草案进行发布前评审。本指南采用了美国心脏病学学会/美国心脏协会2015年推荐意见分类和证据级别标准以及新版美国心脏协会指南格式。结果本指南详细介绍了院前医疗、紧急和急诊评估、静脉和血管内治疗以及院内管理,包括在发病后最初2周内启用的二级预防措施。本指南支持院前和院内卒中医疗系统的一体化概念。结论本指南基于目前可获得的最佳证据。然而,许多情况资料有限,迫切需要对急性缺血性卒中的治疗进行持续研究。William J.

4伴有脑肿胀的大脑和小脑梗死的管理推荐意见美国心脏协会/美国卒中协会对医疗专业人员的声明显示文摘背景和目的关于缺血性卒中后脑肿胀患者的最佳管理方案,仍有许多尚未确定的问题。需要制定相关指南来指导如何处理这种严重并发症,如何提供最佳的综合性神经科和内科治疗,以及在患者病情恶化时如何与面临外科干预复杂决策的家属进行良好的沟通。本科学声明为大脑或小脑半球缺血性卒中伴脑肿胀的患者提供了早期的管理方案。方法写作组利用系统文献综述,参考公开发表的临床和流行病学研究、发病率和死亡率报告、临床与公共卫生指南、权威声明、个人文件以及专家意见,对现有证据进行总结并指出与当前知识水平的差距。写作组通过对MEDLINE、EMBASE和Web of Science数据库进行医学文献计算机检索(最后检索时间为2013年3月,研究对象为成年人)回顾最相关的文献。在美国心脏协会(American Heart Association,ARIA)框架背景下对证据进行组织,根据AHA/美国心脏病学学会基金会以及AHA卒中委员会的证据强度分级方案进行分类。这份声明经过AHA内部的广泛同行评议。结果已有适用于由缺血性梗死引起的半球(累及整个大脑中动脉供血区或更大范围)和小脑(累及小脑后下动脉或小脑上动脉供血区)肿胀的临床标准。幕上半球缺血性卒中伴脑肿胀发生恶化的临床表现包括新发意识障碍或意识障碍加重、脑性上睑下垂以及瞳孔大小变化。在小脑梗死伴肿胀患者中,意识水平下降是脑干受压的结果,因此可能出现早期角膜反射丧失和瞳孔缩小。应制定标准化定义以促进多中心和基于人群的发病率、患病率、危险因素和转归研究。脑肿胀高危患者的识别应包括临床和神经影像学资料。如果大面积卒中患者有必要进入全面复苏状态,则需要收入具备神经监护功能的病房。这些患者最好被收入由技术熟练和经验丰富的医生(如神经重症监护医生或神经血管科医生)负责的重症监护室或卒中单元。综合性医疗管理包括气道管理和机械通气、血压控制、液体管理以及血糖和体温控制。在幕上半球缺血性卒中伴肿胀患者中,不需行常规颅内压监测或脑脊液引流,但神经功能继续恶化的患者应考虑行去骨瓣减压和硬脑膜切开术。去骨瓣减压术在≥60岁的患者中的疗效尚不确定。在神经功能恶化的小脑卒中伴肿胀患者中,应行枕骨下颅骨切除和硬脑膜切开术。当应用脑室造瘘术缓解小脑梗死后梗阻性脑积水时,应同时行枕骨下颅骨切除术以防小脑向上移位导致的病情恶化。幕上半球梗死伴肿胀患者可获得令人满意的转归,但即使行去骨瓣减压术,仍有1/3的患者会遗留严重残疾和完全生活依赖。多数小脑梗死患者在术后能获得可接受的功能转归。结论大脑和小脑梗死伴肿胀是需要立即给予专业神经重症监护、并常需要进行神经外科干预的危重情况。去骨瓣减压术是很多患者的必然治疗选择,经过选择的患者能从中受益匪浅,尽管他们可能会遗留残疾,但仍可生活自理。Eelco F.

5Operative considerations for rectovaginal fistulas显示文摘To describe the etiology, anatomy and pathophysiology of rectovaginal fistulas(RVFs); and to describe a systematic surgical approach to help achieve optimal outcomes. A current review of the literature was performed to identify the most up-to-date techniques and outcomes for repair of RVFs. RVFs present a difficult problem that is frustrating for patients and surgeons alike. Multiple trips to the operating room are generally needed to resolve the fistula, and the recurrence rate approaches40% when considering all of the surgical options. At present, surgical options range from collagen plugs and endorectal advancement flaps to sphincter repairs or resection with colo-anal reconstruction. There are general principles that will allow the best chance for resolution of the fistula with the least morbidity to the patient. These principles include: resolving the sepsis, identifying the anatomy, starting with least invasive surgical options, and interposing healthy tissue for complex or recurrent fistulas.Kevin R Kniery Eric K Johnson Scott R Steele 2015World Journal of Gastrointestinal Surgery2015,7,8:7

7Air quality monitoring using mobile microscopy and machine learning显示文摘Rapid,accurate and high-throughput sizing and quantification of particulate matter(PM)in air is crucial for monitoring and improving air quality.In fact,particles in air with a diameter of≤2.5μm have been classified as carcinogenic by the World Health Organization.Here we present a field-portable cost-effective platform for high-throughput quantification of particulate matter using computational lens-free microscopy and machine-learning.This platform,termed c-Air,is also integrated with a smartphone application for device control and display of results.This mobile device rapidly screens 6.5 L of air in 30 s and generates microscopic images of the aerosols in air.It provides statistics of the particle size and density distribution with a sizing accuracy of~93%.We tested this mobile platform by measuring the air quality at different indoor and outdoor environments and measurement times,and compared our results to those of an Environmental Protection Agency–approved device based on beta-attenuation monitoring,which showed strong correlation to c-Air measurements.Furthermore,we used c-Air to map the air quality around Los Angeles International Airport(LAX)over 24 h to confirm that the impact of LAX on increased PM concentration was present even at 47 km away from the airport,especially along the direction of landing flights.With its machinelearning-based computational microscopy interface,c-Air can be adaptively tailored to detect specific particles in air,for example,various types of pollen and mold and provide a cost-effective mobile solution for highly accurate and distributed sensing of air quality.Yi-Chen Wu Ashutosh Shiledar Yi-Cheng Li Jeffrey Wong Steve Feng Xuan Chen Christine Chen Kevin Jin Saba Janamian Zhe Yang Zachary Scott Ballard Zoltán Göröcs Alborz Feizi Aydogan Ozcan 2017Light(Science & Applications)2017,6,1:5

114号染色体短臂微卫星多态性与鼻咽癌相关性的研究显示文摘鼻咽癌(NPC)是一种多因素复杂疾病。其发病过程涉及EB病毒慢性感染、环境致癌因素及宿主基因之间的相互作用。在这一过程中,那些宿主基因在EB病毒感染及鼻咽癌的发生发展中起了关键作用仍不清楚。本研究的目的是发现与鼻咽癌发生发展中两个关键步骤相关的遗传变异,即EB病毒持续性感染鼻咽部上皮细胞和鼻咽癌的形成。我们在广西梧州市及苍梧县鼻咽癌高发区收集汉族鼻咽癌患者350例、EB病毒壳抗原IgA抗体阳性者(IgA/VCA+)288例和EB病毒壳抗原IgA抗体阴性者(IgA/VCA—)346例。对先前鼻咽癌家系研究显示的鼻咽癌易感区4号染色体短臂(4p15.1~q12)进行了微卫星精细扫描,在18Mb的范围内选择34个微卫星标记,包括319个等位基因,对其进行基因分型。比较分析NPC组和IgA/VCA+组等位基因频率结果显示,9个等位基因与鼻咽癌呈相关,其中5个为易感等位基因(OR=1.51~5.36,P=0.01~0.03),4个为限制性等位基因(OR值为0.3~0.71,P值为0.02~0.045)。比较分析IgA/VCA+组和IgA/VCA-组及比较所有IgA/VCA+者(包括NPC患者)和IgA/VCA-者等位基因频率的结果显示,12个等位基因与EB病毒壳抗原IgA抗体持续存在相关,其中3个在两组比较中均呈显著相关。等位基因D4S3241~136(P=0.004,OR=1.9,95%CI=1.2~3.0)和D4S3347-213(P=0.001,OR=1.6,95%CI=1.2~2.1)可增加EB病毒IgA/VCA抗体形成的危险,为易感基因;而等位基因D4S174.202(P=0.001,OR=0.5,95%CI=0.3~0.7)可限制IgA/VCA抗体的形成。但上述结果经多因素比较校正后,均失去相关性。结果不能确定该区域与非家族性鼻咽癌的形成相关,但本研究却提供了进一步发现鼻咽癌相关基因的研究模式。有关4号染色体短臂与EB病毒慢性持续感染及鼻咽癌的形成仍值得进一步深入研究。郭秀婵 O’BRIEN Stephen J WINKLER Cheryl SCOTT Kevin HUTCHESON Holli DAVID Victor KESSING Bailey 郑裕明 廖建 刘彦 GUY de The 曾毅 2006遗传2006,28,7:2
