目的探讨微动敏感床垫睡眠监测应用于儿童阻塞性睡眠呼吸暂停综合征的价值。方法选择本院2.15年9月至2.17年9月收治的阻塞性睡眠呼吸暂停综合征患儿100例,按照随机数字法分为观察组与对照组,各50例。观察组使用微动敏感床垫式睡眠监测系统,对照组使用常规多导睡眠监测(PSG)系统,比较两组不同睡眠阶段的血氧饱和度、呼吸监测相关指标、睡眠呼吸暂停及夜间周期性腿动发生情况。结果观察组在快动眼睡眠、慢动眼睡眠及苏醒前30 min的血氧饱和度均显著低于对照组(P<0.05);观察组的AI、OAI、HI、睡眠呼吸暂停及夜间周期性腿动发生率显著高于对照组(P<0.05)。结论对于儿童阻塞性睡眠呼吸暂停综合征,使用微动敏感床垫睡眠监测系统进行监测,能提高对呼吸相关参数的监测敏感度、临床诊断效率,从而更好地为临床治疗提供指导。

The origin of the noticeablc magnificent plateau is thought of a key for bringing to light the crustal movement of continent. Several hypotheses so far for the mechanism of the plateau-building have been summarized, which is mainly a collision between the Indian and Tibetan continents. This paper proposes that the plateau-building is resulted by subduction of basins surrounding the plateau. The upper mantle within the Qinghai-Tibet Plateau is subsided, which is governed by gravitational iso-static process of the Earth.

埃达克质火成岩在中国东部,包括燕山带是很常见的,一般认为它们是下地壳不均匀的镁铁质岩石及/或富集的上地幔岩石在高压(≥1.5 GPa)下部分熔融的结果。在燕山带内埃达克岩浆的形成有一个很长的时间(约190～80 Ma),然而岩浆活动的峰期却与约170～130 Ma间有基底岩石卷入的陆壳收缩期相一致。尽管埃达克质岩浆活动的历史很长,但那种把岩浆活动与岩石圈的拆沉效应相联系的模式似乎是不适当的。在该带内,埃达克质与非埃达克质岩浆活动有一部分是同时的,而且在地理分布上也是相间的,这说明了在下地壳和上地幔岩石的部分熔融中成分是相当不均匀的。侏罗纪及白垩纪熔融作用的热源应当是与古太平洋板块俯冲相关的中生代板底垫托的玄武岩浆。除了局部例外,在燕山带,埃达克质岩浆活动的终结和碱性岩浆活动的开始约在130～12. Ma,在此时期收缩作用使东亚大达2.0万km^2.上的地区发生了NW—SE向的区域性伸展作用。强烈的地壳伸展仅局限于华北克拉通北缘分布的少数几个变质核杂岩中。陆壳的伸展减薄合理地解释了130～12. Ma间发生高压埃达克质熔融条件的终结,尽管还有局部年轻的埃达克火山活动(约12.～80Ma)可以在伸展规模有限而厚的地壳依然存在的地区继续出现。燕山区早白垩世的碱性侵入体中的锆石不存在前寒武纪?

地学前缘 2000年第S1期7卷 338-338页

Geological evidences have indicated large\|scale crustal shortening by thrust faultings in Himalaya , such as MCT and MBT. The thrust faulting near Yarlungzampbo suture was also observed. However, it is still unknown to what depth those thrust faultings have been going down into the crust or upper mantle . Seismological evidences indicate that the thrust faultings in Himalaya and southern Tibet have extended to a depth of 80 to 100km , and stopped there. The thrust faultings underneath MCT MBT and Yarlungzampbo suture are closely related to the multiple crustal subductions in Himalaya and southern Tibet. It provides important constraints for the collision process between India and Eurasia. The incomplete crustal subductions in this region suggest that the impinging Indian crust is too light to prevent it going further down, and retreat of crustal subduction is required for the continuing northward {4. of the Indian plate. The multiple crustal subductions are compatible to the multiple episodes of the geological activities in Himalaya and southern Tibet. At first, the crustal subduction was produced at Yarlungzampbo suture , and stopped at a depth of 80～100km. Then, it migrated to the south, other new crustal subductions would start successively at MCT and MBT respectively. They stopped at a depth of 80 to 100km also. Beside the north\|dipping seismic zones in Himalaya and Yarlungzamp bo suture, another gentle south\|dipping seismic zone,extending from Tangula Shan at the surface to the Moho at Yarlungzampbo suture was also observed. It can be interpreted to be an obduction at Tangula Shan. The multiple incomplete crustal subductions in Himalaya and Yarlungzampbo suture highly imply that the impinging Indian crust has been splitted apart from its upper\|most mantle, which may b e subducted deeper into the Eurasian mantle.

前人对四川盆地上三叠统的沉积相进行过很多研究,但迄今为止认识分歧仍然很大。为此,根据数十年的野外露头剖面及岩心观察,结合对岩石薄片鉴定、测井等资料的综合分析,反复思索,认为:①须一段为海湾中形成的海陆交互相沉积;②香二段、香四段、香六段砂岩在盆地中西部主要为三角洲前缘水进河床与河口砂坝至滨湖滩、坝沉积,夹香三段、香五段湖相砂泥;③四川盆地东部的整个上三叠统均为泛滥平原—三角洲平原辫状河道砂和河间湖沼沉积。特别指出,盆地中西部香二段、四段、六段中许多与湖泊有密切联系的正粒度韵律砂体应属水进型三角洲的水进河床充填砂微相,所谓"水下分流河道"一词实际上是与客观情况不太吻合的。
