Cherts in the zhongba melange of the western Yarlung Zangbo Suture Zone(YZSZ) contain well preserved radiolarian assemblages. These radiolarian assemblages indicate that the zhongba melange has middle Jurassic-early Cretaceous remnant, are coeval with those from the central and eastern parts of the YZSZ. Cherts from the Najiu area yield Aalenian to Aptian radiolarians, while cherts interbedded with siliceous mudstones from the Bielongjiala area yield Aptian radiolarians, indicating that terrigenousderived sediments were deposited during early Aptian. The above observations indicate that the entire YZSZ have a similar geochronological framework and thus they underwent similar geological evolution:(1) during the Jurassic, the Neo-Tethys was a wide ocean with pelagic sediments distal from continents;(2) during the Cretaceous(around 130-120 Ma), the Neo-Tethys started to subduct along the southern margin of the Lhasa block, and terrigenous-derived siliceous mudstone began deposition.

Paleogeography is the merger of lithology,depositional environments,tectonic plate movements,topography,climate patterns and ecosystems(reefs,vegetation)through time(e.g.,Scotese,2014,2016,2017;Blakey,2019).The construction of paleogeographic maps using tectonic plate reconstructions requires a multi-year community effort that shares databases,standards and computer projection methods.

Paleogeographic analysis accounts for an essential part of geological research,making important contributions in the reconstruction of depositional environments and tectonic evolution histories(Ingalls et al.,2016;Merdith et al.,2017),the prediction of mineral resource distributions in continental sedimentary basins(Sun and Wang,2009),and the investigation of climate patterns and ecosystems(Cox,2016).

混杂岩是古增生楔存在的标志之一,一般由枕状玄武岩、灰岩、放射虫硅质岩、硅质页岩、砂岩等混乱无序组成。目前"大洋板块地层"(OPS)运用放射虫地层学方法对混乱的增生楔断片进行重建取得了良好效果,并清晰地展示了大洋板块俯冲和洋底物质连续增生的历史。在西藏仲巴地区填图过程中,结合放射虫年代学分析鉴定结果,以OPS重建的思路和理论作为指导,重建了仲巴地区混杂岩的大洋板块地层,并恢复了该区域特提斯洋在洋中脊大洋板块增生至消亡的岩石序列,自下而上分别为侏罗纪海山玄武岩、海山覆盖物侏罗系—白垩系碳酸盐岩、海山周围沉积的侏罗系—白垩系放射虫硅质岩和硅质页岩,以及海沟附近的白垩系陆源碎屑岩等,为特提斯洋大洋板块俯冲的方向、持续时间和古大地构造环境提供了信息。

目的探索病友之家模式在急性心肌梗死患者出院后康复中的应用及其效果。方法选取我院2014年7月-2015年10月急性心肌梗死行介入手术的患者共100例,随机分为对照组和干预组,每组各50例。对照组患者出院时进行常规出院健康指导,干预组患者在此基础上邀请其加入病友之家,参与一系列活动。观察两组患者在出院后12个月的左室射血分数(Left ventricular ejection fraction,LVEF)、左室舒张末期内径(Left ventricular end-diastolic diamete,LVEDD)改善情况、主要不良心脑事件(Major adverse cadiac and cerebral events,MACCE)的发生情况、再入院率。结果干预组出院后12个月的左室射血分数(LVEF%)显著增加、左室舒张末期内径明显低于对照组,MACCE的发生率、再入院率明显低于对照组。结论开展多种方式相结合的病友之家模式能够有效促进急性心肌梗死患者出院后的心脏康复,降低患者MACCE的发生率,从而提高患者的生活质量,降低再入院率。
