研究型军队总医院科研建设的实践与思考

医院的发展模式随着内外环境的变化而从粗放型向集约型过渡,科研水平的提高将对医院全面建设起到良好的支撑引领作用。立足研究型军队总医院建设需求,从科研管理体系、平台构建、品牌打造、技术创新和人才储备建设等方面进行了初步探讨。     

以“五新”推动医院精品学科建设

抓住电子病历应用共享核心 推进数字化医院建设

国家卫生部对电子病历应用水平验收主要是对医院、区域电子病历共享进行验收,意在促进区域协同医疗和全民健康管理。长安医院紧紧抓住全国电子病历试点医院这一契机,努力建设数字化医院,获得国家卫生部“电子病历系统应用水平”考核全国第一,医院建设获得全面推进。     

椎管内分娩镇痛医护体系协调策略

????? 许多医院产科医师和麻醉科医师合作开展椎管内麻醉分娩镇痛已经多年,但依然未成规模,究其原因,人员紧张和科室协调成为制约我国椎管内分娩镇痛广泛开展的瓶颈之一。这是由于参与分娩镇痛的人员虽然职能明晰,但缺乏协调机制,具体工作中又容易脱节所致。在助产士中建立以护士为基础、以麻醉医师为督导的急性疼痛服务体系有良好的理论和工作基础,有助于优化工作流程,提高工作效率,保证产妇安全,推动这一工作的进一步开展。

On the causes of density banding in skeletons of corals of the genus Montastraea

To obtain a reliable climate reconstruction from coral skeletons it is first necessary to understand the way these grow and incorporate information. Thickness of skeletal elements (exothecal and endothecal dissepiments, costae, septa, and theca-wall) as well as the spacing between exothecal and endothecal dissepiments of the four extant Atlantic species of Montastraea (M. annularis, M. faveolata, M. franksi and M. cavernosa) were measured through high and low density bands. Our results show that growth periodicity, controlled by the effect of temperature, is expressed in changes in thickness of costae and exothecal dissepiments in the four studied Montastraea species, with no changes in endothecal elements and theca-wall thickness which, in turn, has implications for research on inclusive records using these species. Spacing between both exothecal and endothecal dissepiments resulted without changes along the high and low density bands, and we found evidence that there is a rhythmical formation of these structures linked somehow to lunar cycles.     

Soil dematiaceous hyphomycetes from Dahingganling Mountain Range, Inner Mongolia, China Ⅰ

A total of 50 isolates of soil dematiaceous hyphomycetes belonging to 39 species in 18 genera were found from the area of Dahingganling Mountain Range. Among them, Monodictys arxanensis is a new species. Chrysosporium fastidium, Exserohilum pedicellatum, Monodictys asperospora, Papulaspora brachiata, Scolecobasidium anelli, Scolecobasidium verruculosum and Ulocladium tuberculatum are new to China. The other 31 taxa which have been previously reported from China are also listed. Specimens （dried cultures） and living cultures of all fungi studied have been deposited in the Herbarium of Shandong Agricultural University： Plant Pathology （HSAUP）.     

Permineralized rhizomes of the Osmundaceae (Filicales): Diversity and tempo-spatial distribution pattern

The family Osmundaceae is among the most primitive ferns of the Filicales, with an extensive fossil record dating back to the Late Paleozoic. Numerous fossil osmundaceous rhizomes have been documented in the geological history. However, the diversity, variation and distribution pattern of permineralized rhizomes remain poorly known. Here we intend to analyze the fossil records with regard to the diversity and distribution pattern of the osmundaceous rhizomes based on available data. To date, about 83 species ascribed to 14 genera of fossil osmundaceous rhizomes have been described worldwide, assigned to two subfamilies, namely, Thamnopteroideae and Osmundoideae. Geologically, two groups (i.e., Thamnopteroideae and Palaeosmunda) have been reported in the Permian. All the Triassic taxa are from the southern hemisphere. Jurassic osmundaceous rhizomes are abundant and widespread throughout the world, most dominant in the southern hemisphere. During the transition of Jurassic to Cretaceous, the diversity of osmundaceous rhizomes declined rapidly. In the Cretaceous, however, the osmundaceous rhizomes from the northern hemisphere surpass those from the southern hemisphere in generic level for the first time. The Cenozoic taxa diversified in the northern hemisphere with the rise of angiosperms. Geographically, the osmundaceous fossil rhizomes have been found in both hemispheres; the major localities include Ural area of the former USSR, Tasmania of Australia, southern Argentina, Antarctica, northern India, central and western part of North America and northern China. We discuss the origin, radiation, and development of the Osmundaceae based on rhizomes, to help further understand the systematic relation and evolutionary history of the family Osmundaceae.
