The coast of southern Hainan island is characterized by wide sandy embayments, which consist of ( i) drowned valleys bounded by steep bedrock hills and only locally receiving sediments, and embayments of various dimensions covered either by (ii) alluvial-deltaic deposits or by (iii) sands of coastal beach ridges/barriers and associated elongated lagoons. During the late Tertiary-Pleistocene the area has experienced isostatic and eustatic movements associated with neotectonics and climatic changes. Such history isrecorded in terraces at various altitudes (SO, 40, 20 m asl) and sequences of coastal sand ridges/baymouth bars. The Holocene variations in sea level and climate are recorded in the dated coastal ridges, coral reef and beachrock. Conditions suitable for reef development started about 8000 a BP. The GPR profiles also show that the internal structures of the sand ridges have composite nature being formed by several superimposed secondary ridges.

北美五大湖区的安大略湖北岸Don Valley Brickyard、Scarborough Bluffs、Bowmanville Bluffs剖面共同构成了北美东北部最长也是最厚的陆地第四纪沉积记录,较完整地记录了晚更新世劳伦泰德冰盖(the Laurentide ice Sheet)的演化.晚更新世劳伦泰德冰盖演化的重建有赖于这些经典剖面中重要沉积地层单元的准确年代学控制.传统的地层年代学主要是依靠少量14C年代,将主要的混杂堆积单元(diamicton)解释为气候变冷环境下的冰川扩张,并与指示全球冰量变化的深海氧同位素曲线一一比对建立起来的.这样建立起来的年代学存在很大的不确定性.20世纪80-90年代的少量热释光年代也不相吻合,最近的13个长石红外释光定年则只集中于Bowmanville Bluffs的一个分层,并未建立整个剖面的地层年代学,使这些经典沉积剖面的年代学一直没有得到系统的建立.应用石英光释光SAR-SGC法测试了Bow manville Bluffs剖面Glaciofluvial Sand单元的2个冰水沉积样品,年代结果分别为(41.6±3.8)ka、(48.1±4.4)ka,分析表明这一年代结果偏老,石英颗粒可能晒褪不完全.由于大测片无法识别晒褪不完全的颗粒,因此,测试更多的剖面序列的光释光年代并尝试采用粗颗粒小测片或单颗粒技术解决样品颗粒晒褪不完全的问题将是必要的.

The Boao coastal system along the eastern coast of Hainan island is a dynamic delta-tidal inlet-barrier formed during the late Holocene. The delta developed inside a shallow lagoon barred by a sandy barrier with a narrow, shallow tidal inlet opening. Two major distributary channels separated by small islands characterize the delta. The lagoon is silting up receiving and trapping sediments from both the river and, in minor measure during storms, through the tidal inlet opening and barrier washovers. The barrier at the tidal inlet is highly dynamic and changes its form, accreting (migrating spit) against the inlet during fair-weather conditions and being eroded during storms and river floods. The delta has almost completely filled the lagoon and major concerns exist on the effect that ongoing large development plans may have on the environment. These concerns include the effect on floods and rate of siltation once banks of the islands have been stabilized and floodwater and sediment load are impeded from spreading over the lowlands, and the effect of increasing pollutant loads from the new facilities on the ecosystems of the increasingly restricting lagoon water and on the seashores.

通过钻孔资料和探地雷达（GPR）反射剖面,揭示了海南岛东部博鳌地区晚更新世以来沙坝-泻湖体系的演化。研究结果显示探地雷达可以很好地提供7-8m深度以上沙体的内部反射结构,岩性特征、沙体平面展布、潜水面深度等参数,是海岸带环境调查的有效手段。对资料的综合分析表明博鳌地区的沙坝-泻湖体系随晚全新世以来海平面的上升经历了基岩侵蚀面→河流、河漫滩相→滨岸浅海、泻湖→沿岸沙坝、半封闭泻湖、河口湾的演化过程,构成了粗-细-粗的沉积旋回。沿岸沙坝出现于早全新世,发育于中全新世,3000年来海平面的微微上升到稳定构成了海岸平原上部的最年轻的砂坝-泻湖、海滩岩、砂堤岩、风成沙丘和现代海滩。

Sedimentary successions and internal structure of the coastal barrier-lagoon system of Boao, eastern Hainan island were studied through utilizing data from test holes and trenches and ground-penetrating-radar (GPR) profiles. During late Pleistocene, fluvial and delta plains developed over an unevenly eroded bedrock during low sea level stand, followed by the formation of littoral and lagoon facies and defined coastal barrier-lagoon-estuary system during the post-glacial uppermost Pleistocene-lower Holocene eustatic rise of the sea level, and the upper Holocene high stand. GPR results show that Yudaitan, a sandy coastal bar backed by a low-laying land (shoal) just east of the active lagoon, is a continuous, parallel and slightly-wavy reflectors indicating homogeneous sandy or sandy gravel sediments, and inclined reflectors partly caused by progradation and accumulation of beach sand and gravel. Quasi-continuous, hummocky and chaotic reflectors from the shoal of Nangang village correspond to mixed accumulation of sands and clay. This research indicates the GPR is a non-intrusive, rapid, and economical method for high-resolution profiling of subsurface sediments in sandy gravelly coast.

近来的研究表明,由于围术期神经肌肉阻滞管理不当,肌肉松弛药(肌松药)残留阻滞及其术后并发症的发生率居高不下。需要重视神经肌肉功能监测仪、肌松药及其拮抗剂的合理应用,以利于改善神经肌肉阻滞管理。欧洲麻醉和重症监护学会(European Society of Anaesthesiology and intensive Care,ESAiC)首次发布围术期神经肌肉阻滞管理临床指南,旨在为临床医生提供最佳医疗管理的循证建议,以提高围术期患者安全。本指南主要聚焦在3个临床问题:肌松药是否有助于成人气管插管?神经肌肉阻滞深度是否影响腹部手术患者的预后?肌松药残留阻滞的诊断和治疗策略有哪些?根据PiCO原则(患者、干预、对照、结局;patient,intervention,comparator,outcome;PiCO)构建临床问题并进行文献检索。初始纳入的临床研究为24 000篇,采用逐步筛选策略,最终临床研究88篇纳入指南分析。应用GRADE方法学(Grading of Recommendations,Assessment,Development and Evaluation,GRADE)对结局指标证据、质量等级进行评价。运用两轮德尔菲法收集专家组建议并形成统一推荐:R1推荐应用肌松药辅助气管插管(1A)。R2推荐应用肌松药以减少气管插管导致的咽部和(或)喉部损伤(1C)。R3推荐在快速顺序诱导插管(rapid sequence induction intubation,RSii)时使用短效肌松药,例如琥珀胆碱1 mg/kg或罗库溴铵0.9~1.2 mg/kg(1B)。R4推荐在需要改善外科手术条件时,加深神经肌肉阻滞深度(1B)。R5尚无足够的证据推荐深度神经肌肉阻滞可减轻术后疼痛或降低围术期并发症的发生率(2C)。R6推荐在拇内收肌处刺激尺神经,定量监测神经肌肉阻滞深度以排除肌松药残留阻滞(1B)。R7推荐应用舒更葡糖钠逆转甾体类肌松药(罗库溴铵、维库溴铵)诱导的深、中及浅度神经肌肉阻滞(1A)。R8推荐在使用新斯的明前,TOFr自行恢复至>0.2,并继续定量监测神经肌肉功能,直至TOFr超过0.9(1C)。
