The middle Permian Cryptospirifer fauna （brachiopod） has hitherto been found in more than 30 localities in the Yangtze Platform, South China. Examination of data from various localities shows that it occurs stratigraphically in three intervals in the range from the upper Kungurian to Wordian. In the Baoshan block in western Yunnan the fauna occurs in the basal part of the Daaozi Formation and is of possibly an early Wordian age. Outside China the Cryptospirifer fauna has been reported from central and northwest Iran and central Turkey, where the fauna may have an age around the Wordian／Capitanian boundary. Rapid global warming since the late Early Permian and possession of other suitable environmental factors such as proper substrate, clastic input and water depth enabled the Gondwana-derived Baoshan Block and related tectono-stratigraphic units in Iran and Turkey to host the Cryptospirifer fauna, a fauna evolved in the Yangtze Platform that is a type area of the Cathaysian province.

In Southwest China, Gondwana-affinity Permo-Carboniferons deposits are known to occur in the Northern Himalayas, the Lhasa Block and the South Qiangtang Block, the Baoshan Block and the Tengchong Bock. The three-fold clastic successions, namely diamictite-pebbly mudstone-dark mudstone and shale are commonly interpreted as representing deposits of glacial-deglacial-postglacial periods in marine environments. Deposits, for example, the Dingjiazhai Formation in the Baoshan Block, the Kongshuhe Formation in the Tengchong Block, the Yongzhu Group and the Poindo Group in the Lhasa Block, are all succeeded by carbonate deposits. This marks a significant change from post-glacial clastic environment to a carbonate environment. Available paleontological data show that the change from post-glacial clastic environment to carbonate environment took place in the Baoshan, Tengchong and Lhasa Block at the beginning of the Artinskian. The carbonate environment in the Baoshan Block was spoiled by the eruption of the Woniusi Basalts, and in the Xainza area of the Lhasa Block was shortly replaced by clastic environment until the Kungurian. In the northern Himalayas limestones began to occur in the Late Permian in a fluctuating manner.

On the basis of existing conodont data, the authors have studied the Late Permian-Early Triassic conodonts of different forms and biofacies in detail. Five conodont biofacies are recognized, from shallow to deep waters 1. Hindeodus conodont biofacies, 2. Pachycladina-Parachi rognathus conodont biofacies, 3. Gondolella -Hindeodus conodont biofacies, 4. Gondolella-Neospathodus conodont biofacies, and 5. Xaniognathus conodont biofacies. Considering the temporal and spatial changes of these conodont biofacies, 3 conodont bloprovinces have been divided. In light of the biofacies changes of each bioprovince, the authors also discuss, in this paper, the regularity of transgression-regression cycles of eastern Tethys and their possible relation to the mass biotic alternation.

西藏拉萨林周地区的下二叠统旁多群的地层层序以前并不十分清楚,其中“杂砾岩”的成因也争议很大。通过详细的野外地质调查和研究,在林周旁多地区新发现了其中部的含有坠石的纹层状粘土岩,并建立了旁多群中部和上部的地层序列。旁多群中部以陆源碎屑少、悬浮泥质为主的欠补偿深水盆地相沉积为特征,而上部以陆源碎屑丰富的滨、浅海相沉积为特征。旁多群自下而上反映了两期岩浆构造事件:第一期发生在该群中部沉积之初,伴随着基性玄武岩的喷发,该群中部沉积时,盆地进入裂谷鼎盛时期,随后进入以旁多群上部为代表的裂谷充填阶段;第二期构造事件可能发生在旁多群和乌鲁龙组沉积之交,乌鲁龙组沉积物中含有大量的长石碎屑、火山岩岩屑和凝灰质沉积岩,指示这期岩浆构造活动的存在。旁多群中的坠石沉积指示旁多群的形成背景是裂谷构造环境下的冰海相。旁多群中的杂砾岩按照成因可以划分为:具有正粒序结构的杂砾岩,为重力流沉积岩,反映侧向水流的搬运;不具有正粒序结构的厚层块状、含有坠石沉积的杂砾岩,为水下冰碛岩,反映冰川、冰筏作用存在,指示大陆上有冰川作用。这种分类和命名有助于石炭-二叠纪冰川发育过程和旋回性的研究,也有助于提高冰海相地层的划分和对比的可靠性和精度。

目的评价右美托咪啶联合利多卡因胶浆对双腔气管插管患者拔管应激反应的影响。方法择期行开胸肺叶切除术患者100例,ASA分级Ⅰ或Ⅱ级,随机分为4组(n=25):对照组、右美托咪啶组、利多卡因胶浆组及联合治疗组(右美托咪啶联合利多卡因胶浆治疗组)。于静脉输注右美托咪啶前(T0)、DLT拔管前(T1)、拔管后5 min(T2)、拔管后10 min(T3)测定血浆中肾上腺素和去甲肾上腺素水平,记录各时点MAP和收率(HR),评估拔管时呛咳程度。结果与T0时比较,4组患者T1时血浆肾上腺素及去甲肾上腺素水平升高,对照组、右美托咪啶组和利多卡因胶浆组T1时MAP、HR升高,对照组T2-3时各指标水平升高(P<0.05);与对照组比较,右美托咪啶组、利多卡因胶浆组及联合治疗组T1、T2、T3时各指标水平及拔管时呛咳程度降低(P<0.05);与联合治疗组比较,右美托咪啶组和利多卡因胶浆组T1时各指标水平及拔管时呛咳程度升高(P<0.05)。结论右美托咪啶联合利多卡因胶浆可减轻双腔气管插管患者拔管时的应激反应。
