| 2 | 黄芪总黄酮对扑热息痛所致肝损伤的防护机理探讨显示文摘目的 :研究黄芪总黄酮对扑热息痛所致肝损伤的防护机理。方法 :用高压液相测定扑热息痛及代谢产物和苯巴比妥诱导睡眠模型研究黄芪总黄酮 (TFA)对扑热息痛的代谢及TFA抗扑热息痛所致损伤的机理。结果 :TFA可明显降低尿中硫醚胺酸的浓度 ,其变化与TFA浓度成反比 ;但对其它代谢产物的影响无明显统计学差异。苯巴比妥诱导小鼠睡眠实验结果显示 ,TFA (10 0mg·kg-1)本身对苯巴比妥代谢无明显影响 (P >0 .0 5 ) ,扑热息痛 (40 0mg·kg-1)可显著延长小鼠的睡眠时间 (P <0 .0 0 1) ;但TFA (10 0mg·kg-1)明显缩短扑热息痛所延长的苯巴比妥诱导的睡眠时间 (P <0 .0 0 5 )。结论 | 汪德清 Critchley Julian AJH 丁保国 马艳青 赵海潞 Thomas G Neil 田亚平 Tomlinson B rian Critchley Lester AH James Anthony Edward | 2001 | 中国中药杂志2001，26，9： | 13 |
| 3 | Relationship between Physical and Chemical Soil Attributes and Plant Species Diversity in Tropical Mountain Ecosystems from Brazil显示文摘Although the high diversity of plant species in the rupestrian fields has been primarily attributed to the existence of a set of distinct habitats, few studies support this assertion. The present study aimed to further investigate the relationship between physical and chemical attributes of soils with the diversity of plant species in this unique ecosystem. The rupestrian field is a unique vegetation formation that covers some of the southeastern Brazilian mountains in the transition of the Atlantic rain forest and the Cerrado(savanna). Different habitats occur according to soil characteristics(e.g., presence of rocks, sand, fertility, hydrology, etc.). These attributes ultimately influence the vegetation that is highly adapted to the harsh edaphic and climatic mountain conditions. Five distinct habitats were studied by us: rocky outcrops, peat bogs, sandy bogs, quartz gravel fields, and 'cerrado'(savanna). A floristic survey indicated that four families are found at greater frequency: Poaceae, Asteraceae, Cyperaceae, and Leguminosae. The greatest diversity of plant species was found in the rocky outcrops habitat, followed by cerrado, peat bog, quartz gravel grassland, and sandy bogs, respectively. The main difference in the floristic composition among these habitats was related to the dominant species. Trachypogon spicatus(Poaceae) was the most dominant species in the rocky outcrops, Axonopus siccus(Poaceae) in the peat bogs, Lagenocarpus rigidus(Cyperaceae) in the sandy bogs, Schizachyrium tenerum(Poaceae) in the cerrado, while Vellozia sp. 8(Velloziaceae) dominated the vegetation in the quartz gravel grassland. This study demonstrated that physical and chemical soil properties strongly related the diversity of plant species occurring in the different habitats of rupestrian fields. | Ferna de CARVALHO Edward Luis GODOY Francy J.

| 4 | Dirichlet Process Gaussian Mixture Models:Choice of the Base Distribution显示文摘In the Bayesian mixture modeling framework it is possible to infer the necessary number of components to model the data and therefore it is unnecessary to explicitly restrict the number of components.Nonparametric mixture models sidestep the problem of finding the'correct'number of mixture components by assuming infinitely many components.In this paper Dirichlet process mixture(DPM) models are cast as infinite mixture models and inference using Markov chain Monte Carlo is described.The specification of the priors on the model parameters is often guided by mathematical and practical convenience.The primary goal of this paper is to compare the choice of conjugate and non-conjugate base distributions on a particular class of DPM models which is widely used in applications,the Dirichlet process Gaussian mixture model (DPGMM).We compare computational efficiency and modeling performance of DPGMM defined using a conjugate and a conditionally conjugate base distribution.We show that better density models can result from using a wider class of priors with no or only a modest increase in computational effort. | Dilan Grür Carl Edward Rasmussen | 2010 | Journal of Computer Science & Technology2010，25，4： | 5 |
| 5 | Gastric intestinal metaplasia is associated with gastric dysplasia but is inversely correlated with esophageal dysplasia显示文摘AIM To determine which clinical factors might be associated with gastric intestinal metaplasia(IM) in a North American population.METHODS Pathology and endoscopy databases at an academicmedical center were reviewed to identify patients with and without gastric IM on biopsies for a retrospective cohort study. Patient demographics, insurance status, and other clinical factors were reviewed.RESULTS Four hundred and sixty-eight patients with gastric IM(mean age: 61.0 years ± 14.4 years, 55.5% female) and 171 without gastric IM(mean age: 48.8 years ± 20.8 years, 55.0% female) were compared. The endoscopic appearance of atrophic gastritis correlated with finding gastric IM on histopathology(OR = 2.05, P = 0.051). Gastric IM was associated with histologic findings of chronic gastritis(OR = 2.56, P < 0.001), gastric ulcer(OR = 6.97, P = 0.015), gastric dysplasia(OR = 6.11, P = 0.038), and gastric cancer(OR = 6.53, P = 0.027). Histologic findings of Barrett's esophagus(OR = 0.28, P = 0.003) and esophageal dysplasia(OR = 0.11, P = 0.014) were inversely associated with gastric IM. Tobacco use(OR = 1.73, P = 0.005) was associated with gastric IM.CONCLUSION Patients who smoke or have the endoscopic finding of atrophic gastritis are more likely to have gastric IM and should have screening gastric biopsies during esophagogastroduodenoscopy(EGD). Patients with gastric IM are at increased risk for having gastric dysplasia and cancer, and surveillance EGD with gastric biopsies in these patients might be reasonable. | Justin M Gomez James T Patrie Wissam Bleibel Jeanetta W Frye Bryan G Sauer Vanessa M Shami Edward B Stelow Christopher A Moskaluk Andrew Y Wang | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，2： | 3 |
