Background Th. diagnosis of metabolic sy.drome indicates a clustering of metabolic imbalances wh.ch.in sum h.ve been recognized as a major predictor of cardiovascular and all-cause mortality. Th. aim of th.s study.was to assess th. level of under-ph.rmacy.and poly.pbarmacy.and its prognostic impact in elderly.patients with.metabolic sy.drome. Meth.ds Retrospective ch.rt-review at a tertiary.medical center, of 324 patients greater th.n 65 y.ars of age wh. met th. International Diabetes Foundation criteria for metabolic sy.drome diagnosis [Body.Mass Index （BMI）〉 30 kg/m2, diagnosis of ty.e 2 diabetes, h.0}ertension, and dy.lipidemia]. Results Th.re were 60 （18.5%） patients in th. low （〈 5） medication burden group, 159 （49.1%） in th. medium （〉 5 and 〈 10） medication burden group, and 105 （32.4%） in th. h.gh.（〉 10） medication burden group. At baseline, th. groups differed only.by.sy.tolic blood pressure. At two y.ars follow-up, th. medium group h.d significantly.better improvement in h.gh.density.lipoprotein ch.lesterol （h.L-C）, low density.lipoprotein ch.lesterol （LDL-C）, h.Alc, and sy.tolic blood pressure compared to th. low medication burden group and significantly.better improvement in trigly.erides, h.emoglobin Alc （h.Alc） and sy.tolic blood pressure compared to th. h.gh.medication group. Decrease in h.L-C was th. only.variable associated with.strokes. h.gh.medication burden predicted h.spitalization burden. Th. number of anti-h.0}ertensives, h.story.of tobacco use, low and h.gh.medication burdens and decrease in h.L-C were all associated with.death. Conclusions Both.poly.ph.rmacy.and under-ph.rmacy.are associated with.a decreased th.rapeutic benefit among patients with.metabolic sy.drome in terms of important laboratory.measurements as well as clinical outcomes such.as my.cardial infarctions, h.spitalization, and death.

We carried out th.s research.at Abu-Gaddaf Natural Forest Reserve (ANFR) wh.ch.is located east of Blue Nile River, in Blue Nile State, Sudan. It aims at exploring tree composition assessing th.ir diversity.indices, and ecological importance values. For survey.of ty.es and estimation of density.of tree species in th. forest, we randomly.distributed 97 circular sample plots (0.1 h.ctare (h.)). In each.sample plot we identified all trees to th. species level, recorded th.ir frequencies and computed species diversity.and importance value indices (IVI). A total of 13 tree species, wh.ch.belong to 12 genera and nine families, were identified in th. tree lay.r of th. forest. Mean tree density.in ANFR was 116 trees/h., composed mainly.of Boswellia papy.ifera (Del.) h.ch.t. (48), followed by.Combretum h.rtmannianu (19) and Lannea fruticosa (18). Fabaceae was th. most common family.followed by.Combretaceae and Malvaceae. B. papy.ifera Delile h.ch.t was th. most abundant wh.le Acacia sey.l was th. least abundant species. Species rich.ess (R = 1.71), evenness (E = 0.69), dominance (0.24) indices and Simpson’s Index of Diversity.(D' = 0.76) suggest a moderate diversity. moderate numbers of individuals in each.species and a moderate community.stability. Th. research.provides empirical results on diversity.and ecological importance value of species, signifies th. urging need to safeguard th.eatened species and to prioritize th.m for conservation, as well as th. need to promote management of abundant species to provide multiple forest ecosy.tem services.

维特根斯坦的《逻辑哲学论》从第一页开始就一直是个谜,至今依然如此。根据其开篇断言,事实总和构成世界,而事态总和划定逻辑可能性空间。但事实是什么?可能事态是什么?我们为何需要考虑它们的总和?弗雷格和罗素是第一批努力应对这些解释性问题的人。《逻辑哲学论》日益增多的二手文献表明我们是多么容易沉溺于其诠释学中。然而,更重要的问题是,我们能从维特根斯坦的字里行间取到哪些实质性哲学教益。事实表明,至少有三条教益。第一条是,罗素和《逻辑哲学论》时期的维特根斯坦非常依赖的“事实”概念在哲学上是脆弱的。相反,我们的注意力要转向世界的“事实性”这一更宽泛的概念。第二条是,我们能够、也必须从事实和模态两方面来思考世界,但如此做时,我们必须把可能性的、而非必然性观念作为初始的,同时必须把可能性看作是纯然虚拟的、而非事实的。第三条是,如果我们要理解逻辑、科学和伦理,就必须将世界视为一个整体。
