背景本文旨在观察不同速率输注瑞芬太尼是否会降低使脑电双频指数（bispectral index，BIS）≤50的丙泊酚EC50（半数有效浓度）值。方法将72例ASA分级Ⅰ或Ⅱ级拟行气管内插管并靶控输注（TCI）丙泊酚维持麻醉的成人患者，随机分为6组。瑞芬太尼输注速率分别为：B组0．1μg·kg^-1·min^-1,C组0．15μg·kg^-1·min^-1,D组0．2μg·kg^-1·min^-1,E组0．3μg·kg^-1·min^-1,F组0．4μg·kg^-1·min^-1,A组作为对照组不使用瑞芬太尼。在同一浓度瑞芬太尼组中，以第1例患者对TCI4μg/ml丙泊酚的反应决定岳一例患者的效应室浓度（Dixon的“序贯法”）。如果BIS〉50，后一例患者TCI丙泊酚的效应室浓度增加，如果BIS≤50，后一例患者TCI丙泊酚的效应室浓度则减少。同时研究了联合用药的血流动力学效应。结果EC50变化范围为2．4-2．9μg/ml.未发现瑞芬太毫对丙泊酚EC50的累加效应。但是未使用瑞芬太尼的空白对照组对丙泊酚的反应差异较大。使用瑞芬太尼组患者心率下降。结论瑞芬太昆输注不会减少无刺激麻醉患者丙泊酚需求量。在联合输注瑞芬太尼时不应当降低丙泊酚TCI浓度．

AIM To correlate the length of endoscope hang time and number of bacteria cultured prior to *** Prospectively, we cultured specimens from 19 gastroscopes, 24 colonoscopes and 5 side viewing duodenoscopes during the period of 2011 to 2015. A total of 164 results had complete data denoting date of cleansing, number of days stored and culture results. All scopes underwent initial cleaning in the endoscopy suite utilizing tap water, and then manually cleaned and flushed. High level disinfection was achieved with a Medivator~? DSD(Medivator Inc., United States) automated endoscope reprocessor following manufacturer instructions, with Glutacide~?(Pharmax Limited, Canada), a 2% glutaraldehyde solution. After disinfection, all scopes were stored in dust free, unfiltered commercial cabinets for up to 7 d. Prior to use, all scopes were sampled and plated on sheep blood agar for 48 h; the colony count was obtained from each plate. The length of endoscope hang time and bacterial load was analyzed utilizing unpaired t-tests. The overall percentage of positive and negative cultures for each type of endoscope was also calculated. RESULTS All culture results were within the acceptable range(less than 200 cfu/mL). One colonoscope cultured 80 cfu/mL after hanging for 1 d, which was the highest count. ERCP scopes cultured at most 10 cfu, this occurred after 2 and 7 d, and gastroscopes cultured 50 cfu/mL at most, at 1 d. Most cultures were negative for growth, irrespective of the length of hang time. Furthermore, all scopes, with the exception of one colonoscope which had two positive cultures(each of 10 cfu/mL), had at most one positive culture. There was no significant difference in the number of bacteria cultured after 1 d compared to 7 d when all scopes were combined(day 2: P = 0.515; day 3: P = identical; day 4: P = 0.071; day 5: P = 0.470; day 6: P = 0.584; day 7: P = 0.575). There was also no significant difference in the number of bacteria cultured after 1 day compared

在综合大洋钻探计划308航次中，使用孔隙压力贯人仪分别在墨西哥湾的深水区和路易斯安娜近海的U1322和U1324站位海底下200m内进行了测量，测量到的超压达到了流体静有效应力（λ＊=（u-uk）／（α′th））的60％-70％。强超压出现在低渗透性的泥岩层中，其中有多个非常大的更新世海底滑坡。在U1324站位，海底200m之下的孔隙压力显著下降：在泥岩、粉砂岩和砂岩的交互层中没有海底滑坡。我们认为所观察到的强超压是由来自古密西西比河的低渗透率物质的快速沉积所导致的。

Ursa盆地水深1000m，位于密西西比峡谷的东部隆起上，是研究大型无震滑坡现象的超级天然实验室。近期的研究表明，本地区有记载的地震活动有可能是由浅层重力滑动而不是深层构造作用导致的。在Ursa盆地，块体运移沉积物广泛存在，其时空关系在多波束以及地震反射资料中都有显示。2005年6月，综合大洋钻探项目（IODP）308航次在靠近全新世大滑坡以及泥火山型流体溢出构造附近钻了三个孔，钻穿了更新世-全新世一系列块体运移沉积物，采集了这几个钻孔的测井、沉积学以及土工资料，
