| 1 | Grain-size Characteristics of Sediments Formed Since 8600 yr B.P. in Middle Reaches of Yarlung Zangbo River in Tibet and Their Paleoenvironmental Significance显示文摘Widespread aeolian sediments have been found in the middle reaches of the Yarlung Zangbo River, China. The grain-size characteristics of sediments from Cha’er Section in the area were analyzed. The results show that the section include one stratum of paleo-mobile dunes, four strata of paleo-semi-fixed dunes, two strata of paleo-fixed dunes, one stratum of sandy immature soils. The paleo-mobile and paleo-semi-fixed dune sand in this section are simi- lar to modern aeolian sand in either grain-size composition or Mz and σ distribution. Compared the above types of dunes each other, the content of sand substance decreases, while the content of silt and clay increases for paleo-fixed dunes and sandy immature soils. Combined with age data for each stratum, the analysis shows that these strata are the products of climate changes and the evolution of aeolian landforms. The evolutionary sequence of the paleoclimate and of aeolian activities in the valley since 8600 yr B.P. reveals four stages: 8600–5700 yr B.P., when the paleoclimate was cold and dry, with strong winds, thereby activating dunes; 5700–3600 yr B.P., when it was warm and wet, with weak winds, causing dunes to undergo soil-forming processes; 3600–1900 yr B.P., when climate shifted from cold-dry with strong winds to warm-wet with weak winds, and activated dunes were fixed again; and 1900 yr B.P. –present, when the climate became fine, with weak winds, fixing dunes again. | ZHENG Yinghua WU Yongqiu LI Sen TAN Lihua GOU Shiwei ZHANG Hongyan | 2009 | Chinese Geographical Science2009，19，2： | 10 |
| 2 | Effect of Yang-activating and stasis-eliminating decoction from Traditional Chinese Medicine on intestinal mucosal permeability in rats with ulcerative colitis induced by dextran sulfate sodium显示文摘OBJECTIVE: To evaluate the effect of decoction prepared with Yang-activating and stasis-eliminating medicinals from Traditional Chinese Medicine(TCM) on the intestinal mucosal permeability in rats with ulcerative colitis induced by dextran sulfate sodium(DSS).METHODS: Totally 55 male Wistar rats(body weight of 170-190 g) were randomly divided into the blank group(n = 10) and the model duplication group(n = 45). The blank group was not intervened, while the other was modeled with 5% dextran sulfate sodium by gavaging in a dosage of4 m L per day to induce ulcerative colitis, a total of7 days. Then, the model rats were divided into model blank group, mesalazine group and TCM group,and each group was consisted of 15 rats. They were given retention enema 10 min with normal saline,mesalazine enema(0.036 g/m L), and Yang-activating and stasis-eliminating decoction [0.54 g/m L of a decoction boiled by Puhuang(Pollen Typhae), Xiebai(Bulbus Allii Macrostemonis) and Wulingzhi(Faeces Trogopteri)] for 10 days respectively. Afterwards,all of the rats were evaluated by disease activity index(DAI), histological changes of distal colon, expression of occludin protein and ultrastructure of intestinal epithelial cells. Furthermore, ratio of lactulose to mannitol(L/M) discharged in urine was evaluated.RESULTS: Comparing the results between TCM and model control groups, scores of DAI and histological lesions decreased significantly(P = 0.000 <0.01), ultrastructures of intestinal epithelial cells and tight junctions were more complete. The expression of occludin protein(P = 0.001 < 0.01) increased while the L/M value decreased significantly(P = 0.000 < 0.01) in TCM group. There was no statistical difference between the TCM and mesalazine groups in results of each item(P > 0.05).CONCLUSION: The decoction prepared with Yang-activating and stasis-eliminating TCM medicianls can restore intestinal mucosal epithelial cells and tight junctions the model rats with ulcerative colitis; it can reduce histological lesions and protect the permeability of intestinal mucosa barrier in the rats as well. | Shi Lijie Shi Lei Liu Leilei Feng Xiuxian Wang Jing Yang Qiang Chai Shiwei Gou Jing Zang Fenglin He Sufei | 2017 | Journal of Traditional Chinese Medicine2017，37，4： | 7 |
