1Intrahepatic cholestasis of pregnancy:When should you look further?显示文摘Pruritis with abnormal liver function tests is the classical presentation of intrahepatic cholestasis of pregnancy(ICP),a condition associated with significant fetal complications.Although the etiology of ICP is unclear in many cases,certain features of the clinical presentation should alert the practitioner to the possibility of an underlying metabolic defect, which may not only affect subsequent pregnancies, but may be an indicator of more serious subsequent liver disease.We report a kindred of Anglo-Celtic descent,among whom many members present with ICP,gallstones or cholestasis related to use of oral contraception.Genetic studies revealed a novel mutation in the ABCB4 gene,which codes for a phospholipid transport protein.The clinical significance of this mutation and the importance of identifying such patients are discussed.Winita Hardikar Shivani Kansal Ronald P J Oude Elferink Peter Angus 2009World Journal of Gastroenterology2009,15,9:22
2Observation of ocean current response to 1998 Hurricane Georges in the Gulf of Mexico显示文摘The ocean current response to a hurricane on the shelf-break is examined. The study area is the DeSoto Canyon in the northeast Gulf of Mexico, and the event is the passage of 1998 Hurricane Georges with a maximum wind speed of 49 m/s. The data sets used for analy- sis consist of the mooring data taken by the Field Program of the DeSoto Canyon Eddy Intrusion Study, and simultaneous winds ob- served by NOAA (National Oceanic and Atmospheric Administration) Moored Buoy 42040. Time-depth ocean current energy density images derived from the observed data show that the ocean currents respond almost immediately to the hurricane with important differ- ences on and off the shelf. On the shelf, in the shallow water of 100 m, the disturbance penetrates rapidly downward to the bottom and forms two energy peaks, the major peak is located in the mixed layer and the secondary one in the lower layer. The response dissipates quickly after external forcing disappears. Off the shelf, in the deep water, the major disturbance energy seems to be trapped in the mixed layer with a trailing oscillation; although the disturbance signals may still be observed at the depths of 500 and 1 290 m. Verti- cal dispersion analysis reveals that the near-initial wave packet generated off the shelf consists of two modes. One is a barotropic wave mode characterized by a fast decay rate of velocity amplitude of 0.020 s-1, and the other is baroclinic wave mode characterized by a slow decay rate of 0.006 9 s-1. The band-pass-filtering and empirical function techniques are employed to the frequency analysis. The results indicate that all frequencies shift above the local inertial frequency. On the shelf, the average frequency is 1.04f in the mixed layer, close to the diagnosed frequency of the first baroclinic mode, and the average frequency increases to 1.07f in the thermocline. Off the shelf, all frequencies are a little smaller than the diagnosed frequency of the first mode. The average frequency decreases from 1.035f in the mixed layer to 1.02f in the thermocline, implying a trend for the shift in frequency of the oscillations towards f with the depth.ZHENG Quanan LAI Ronald J HUANG Nortlen E PAN Jiayi LIU W Timothy 2006Acta Oceanologica Sinica2006,25,1:20
3Variation and mechanisms of clastic reservoir quality in the Paleogene Shahejie Formation of the Dongying Sag, Bohai Bay Basin, China显示文摘Reservoir quality varies greatly in the Shahejie Formation in the Dongying Sag. It is essential to analyze the variation and mechanisms of reservoir quality for determining the controlling factors based on cores, porosity measurements and fluid inclusion techniques and so on. The sandstones in the fluvial,(fan) delta-front have the best reservoir quality due to the depositional conditions mechanically controlling the petrology configuration and the primary porosity, and chemically influencing the diagenesis and development of secondary pores. The activity of the boundary faults and the sedimentary facies dominate the variation of reservoir quality in different areas and intervals. The reservoir quality varies with the position of sandstone beds in different vertical models of sandstone and mudstone. This mainly arose from the strong cementation or strong dissolution in the sandstone caused by the diagenesis evolution of adjacent mudstone. With higher oil saturation reservoir quality is better because the hydrocarbon charge favors dissolution and restricts cementation. Diagenesis, depositional conditions and tectonic setting are the key controls of reservoir quality in the Shahejie Formation of the Dongying Sag.Zhang Qin Zhu Xiaomin Ronald J Steel Zhong Dakang 2014Petroleum Science2014,11,2:16
485岁及以上老年冠心病患者经皮冠状动脉支架治疗的临床观察显示文摘目的探讨85~94岁冠心病患者经皮冠状动脉支架治疗的疗效和预后。方法回顾性分析90例85岁以上冠心病患者经皮冠状动脉支架治疗的临床和造影特点、住院期间和长期疗效。结果90例中,21例应用金属裸支架(BMs),69例应用药物洗脱支架(DES)。三支病变41例,2支病变21例,单支病变28例。手术成功率为94.4%,术前与术后TIMI-3级血流比例分别为72.2%和94.4%。手术相关并发症为15.6%,主要为冠脉夹层(11.1%)。住院期间主要心血管不良事件(MACE)为7.8%,其中DES组住院期间MACE为5.8%,BMS组为14.3%。DES组出现2例严重出血。86例患者随访1年时,总的MACE为4.6%,其中DES组为6.0%,BMS组没有任何MACE。DES组出现1例脑卒中和1例严重出血。47例患者随访2年时,总的MACE为14.9%,其中DES组MAcE为19.4%,BMS组无任何MACE。DES组1例发生严重出血,BMS组1例发生脑卒中。多因素C0x回归分析表明,肌酐水平和高血压是影响长期预后的重要因素。结论85岁以上冠心病患者经皮冠状动脉支架治疗手术成功率较高,住院期间和长期的MACE事件发生率较低,并存高血压和严重肾功能不全的患者MACE的发生率相对较高。马涵英 周玉杰 Ronald J Dick 赵迎新 吴小滢 梁静 杨丽霞 张琳琳 2008中华老年医学杂志2008,27,7:8
5牧草如何生长——植物生长与放牧管理之关联(英文)显示文摘适当管理饲料饲草资源的基本原则是理解多年生牧草如何生长。长期以来 ,对根系生长有了基本的了解 ,对去叶和环境对根系生长的影响也知之甚多。然而 ,对去叶、干旱及其他环境因素对多年生牧草的影响以及这些牧草对去叶的反应缺乏应有的理解。从牧草返青到开花 ,植物处于短枝阶段 ,适度放牧并不对多年生牧草的健康和活力造成危害 ,因为植物会弥补其失去的叶片。然而 ,当牧草从短枝向长枝阶段 (节间伸长和开花期 )转移时 ,碳水化合物主要用于节间伸长和开花过程。在开花后和休眠前期 ,碳水化合物主要向茎基和植物基部转移 ,以供来年新枝条的发育。因此 ,在花后和休眠前期 ,放牧系统必须被调节到“无放牧”状态。“无放牧”状态 ,如休息、轮牧、延迟轮牧和快速轮牧制 ,其价值在于这种定期的禁牧可提高多年生牧草的活力 ,改善草地的健康状况 ,并且在不利的环境条件下 。Ronald E Sosebee David B Wester J Carlos Villalobos Carlton M Britton Changgui Wan Hisham Nofal 2005草业学报2005,14,1:8
6Molecular mechanism and functional consequences of lansoprazole-mediated heme oxygenase-1 induction显示文摘AIM:To investigate the molecular mechanism and functional consequences of heme oxygenase-1(HO-1) activation by lansoprazole in endothelial cells and macrophages. METHODS:Expression of HO-1 mRNA was analyzed by Northern blotting.Western blotting was used to determine the HO-1 and ferritin protein levels. NADPH-dependent reactive oxygen species(ROS) formation was measured with lucigenin-enhanced chemiluminescence.HO-1 promoter activity in mouse fibroblasts,stably transfected with a 15-kb HO-1 gene that drives expression of the reporter gene luciferase, was assessed using in vivo bioluminescence imaging. RESULTS:Lansoprazole increased HO-1 mRNA levels in endothelial cells and HO-1 protein levelsin macrophages.In addition,lansoprazole-induced ferritin protein levels in both cell systems.Moreover, induction of the antioxidant proteins HO-1 and ferritin by lansoprazole was followed by a decrease in NADPH- mediated ROS formation.The radical scavenging properties of lansoprazole were diminished in the presence of the HO inhibitor,chromium mesoporphyrin IX.Induction of HO-1 gene expression by lansoprazole was not related to oxidative stress or to the activation of the mitogen-activated protein kinase pathway. However,the phosphatidylinositol 3-kinase inhibitor LY294002 showed a concentration-dependent inhibition of HO-1 mRNA and promoter activity. CONCLUSION:Activation of HO-1 and ferritin may account for the gastric protection of lansoprazole and is dependent on a pathway blocked by LY294002.Stephanie Schulz-Geske Kati Erdmann Ronald J Wong David K Stevenson Henning Schrder Nina Grosser 2009World Journal of Gastroenterology2009,15,35:7
