作者： Jie Han Jian Wang Jiaoying H Wang Department of Digestology the First Affiliated Hospital of Henan University of Chinese Medicine Queensland Herbarium Department of Environment and Resource ManagementBrisbane Botanic Gardens School of Pharmacy University of Queensland

OBJECTIVE: To compare the effects of a Chinese herbal suppository(Jianpi suppository) and Western Medicine(mesalazine) on hemorheology and CD62p in patients with ulcerative colitis(UC).METHODS: In a randomized trial, 120 mild to moderate UC patients were randomly divided into two equal groups. The Jianpi suppository group used Chinese herbal suppository rectally, while the mesalazine group was treated with mesalazine tablets orally. Two 15-day courses of treatment were carried out in both groups. Changes in the hemorheology and CD62p indices in patients were ***: The hemorheology and CD62p indices in the Jianpi suppository group decreased significantly more than those of the mesalazine ***: Jianpi suppository is effective in improving the hypercoagulability of UC patients, and therefore may be worth using in clinical practice.

Why ‘the uplift of the Tibetan Plateau’ is a myth

National Science Review 2021年第1期8卷 156-174页

作者： Robert A.Spicer Tao Su Paul J.Valdes Alexander Farnsworth Fei-Xiang Wu Gongle Shi Teresa E.V.Spicer Zhekun Zhou CAS Key Laboratory of Tropical forest Ecology Xishuangbanna Tropical Botanical Garden Chinese Academy of Sciences Center of Plant Ecology Core Botanical GardensChinese Academy of Sciences School of Environment Earth and Ecosystem Sciences The Open University School of Geographical Sciences University of Bristol Key Laboratory of Vertebrate Evolution and Human Origins Institute of Vertebrate Paleontology and PaleoanthropologyChinese Academy of Sciences State Key Laboratory of Palaeobiology and Stratigraphy Nanjing Institute of Geology and Palaeontology and Center for Excellence in Life and PaleoenvironmentChinese Academy of Sciences

The often-used phrase ‘the uplift of the Tibetan Plateau’ implies a flat-surfaced Tibet rose as a coherent entity, and that uplift was driven entirely by the collision and northward movement of India. Here, we argue that these are misconceptions derived in large part from simplistic geodynamic and climate modeling, as well as proxy misinterpretation. The growth of Tibet was a complex process involving mostly Mesozoic collisions of several Gondwanan terranes with Asia, thickening the crust and generating complex relief before the arrival of India. In this review, Earth system modeling, paleoaltimetry proxies and fossil finds contribute to a new synthetic view of the topographic evolution of Tibet. A notable feature overlooked in previous models of plateau formation was the persistence through much of the Cenozoic of a wide east–west orientated deep central valley, and the formation of a plateau occurred only in the late Neogene through compression and internal sedimentation.

DEAR EDITOR,Muntjac deer(Cervidae: Muntiacus) are often cited as an excellent model for the study of vertebrate evolution due to their fast rate of change in chromosome number among vertebrates. However, the phylogenetic relationships within Muntiacus generally, and the taxonomic status of Muntiacus gongshanensis specifically, remain unclear.
