研究远古历史的科学家们已有大批惊奇发现,并利用这些发现来勇敢预测人类未来。201504/367576Ceramic figures like these were made in huge numbers for about 50 years, around 700. Their sole purpose was to be placed in high-status tombs. They have been found all around the great Tang cities of north-west China, where Liu Tingxun held office. The ancient Chinese believed you needed to have in the grave all the things which were essential to you in life. So the figures were just one element in the total contents of Liu Tingxuns tomb, which would also have contained sumptuous burial objects of silk and lacquer, silver and gold. While the animal and human statues would serve and entertain him, the supernatural guardian figures warded off malevolent spirits. You could hardly make better preparation for being dead!公元700年左右,类似的陶俑在五十年间被大量制造,而其唯一用途便是立于位高权重者的坟墓之中。在刘廷荀任职的中国西北部,大型城市大量出土了这种陶俑。古代中国人认为,人应该用一切在世时的必需品作陪葬,因而陶俑只是刘廷苟墓葬的一部分,此外还有可观的丝绸、漆器、白银、黄金等奢侈物品。人俑与兽俑能够侍和取悦墓主,神兽俑则用于驱邪镇魔。Between their manufacture and their entombment, the ceramic figures would have been displayed to the living only once, when they were carried in the funeral cortege. They were never intended to be seen again. Once in the tomb, they took up their unchanging positions around the coffin, and then the stone door was firmly closed for eternity. A Tang poet of the time, Zhang Yue, commented:从制造完工到人葬,这些陶俑应该只有一次在世人面前露面的机会,即在出殡时被运往墓地的过程中,此后便该永不再见天日。进入墓室之后,它们便按照一定位置围绕若棺木摆放,其后石门会被永久闭合。其时有位诗人张说评价道:;All who come and go follow this road,往来皆此路,But living and dead do not return together.;生死不间归。Like so much else in eighth-century China, the production of ceramic figures like these ones was controlled by an official bureau, just one small part of the enormous civil service that powered the Tang state.与8世纪中国的各种物品一样,陶俑制造业受某个官方部门的控制,而该部门只是维系唐朝社会运行的庞大官吏系统中的一小部分。201601/422583According to the celiac sprue association根据乳糜泻研究协会的说法there are three major steps that are taken in order to诊断一个人是否患有乳糜泻diagnose a person with celiac disease.需要三个主要的步骤The first step includes a thorough physical examination第一步是进行一个全面的身体检查to look for any signs of celiac disease看被检查人是否有乳糜泻预兆such as fatigue or weight loss.比如疲惫和体重下降A blood panel is also conducted, sometimes referred to还要进行全血细胞计数as a celiac blood panel to look at有时被称为腹腔全血细胞计数other indicators of celiac disease such as antibodies.来检查其中是否有乳糜泻的预兆,如出现抗体Second, a multi-sample biopsy of the duodenal portion第二步,对十二指肠进行多样本组织检查of the intestine is done in order to look at查看是否有由麦胶蛋白引起的possible damage from the gluten.可能的损害The third step includes implementing第三步是the gluten-free diet.执行无麦胶蛋白饮食When the persons health begins to improve当健康状况开始改善的时候symptoms start to diminish and the intestinal villi乳糜泻的症状就会逐渐消失start to repair themselves celiac disease is diagnosed.小肠绒毛也会进行自我修复Please be aware that it is important to keep gluten请注意为了保诊断的准确性in the diet for an accurate diagnosis.要在食品中保留麦胶蛋白Removal of gluten too early before seeing a physician如果去医院检查之前就提前不吃含有can remove signs and symptoms of celiac disease麦胶蛋白的食物,可能会导致乳糜泻的一些症状needed for a successful diagnosis.消失,从而无法做出正确的诊断As you can see in this diagram这张图显示的是there are three different areas of the intestine.三个不同区域The duodenum is the portion of the intestine十二指肠紧连胃部that immediately follows the stomach and也正是where biopsy samples需要从这里提取样本are taken to diagnose celiac disease.进行乳糜泻诊断Now that you understand现在你已经明白了how celiac disease is diagnosed and that乳糜泻如何诊断someone with celiac disease needs to follow乳糜泻患者应该a strict gluten-free diet.严格执行无麦胶蛋白饮食Lets discuss what gluten is现在我们来讨论一下何为麦胶蛋白and where you may find it in the food supply.在何种食物中可以找到麦胶蛋白Gluten is a protein麦胶蛋白是一种蛋白质that gives b dough elasticity在二氧化碳作用下which allows it to rise without collapsing可以使面团膨胀while trapping the CO2.并具有弹性Gluten is what gives b and b-like products麦胶蛋白可以使面包和面包类产品a desirable volume and texture.按人们的要求呈现出不同的大小和质地It is found in wheat, rye and barley as well as麦胶蛋白存在于小麦,黑麦和大麦以及all wheat derivatives including bulgar, couscous麦类衍生品中,如碾碎的干小麦,蒸粗麦粉,面筋mataza, seitan, semolina, triticale, spelt, kamut粗粒小麦粉,黑小麦,斯佩尔特小麦and einkorn and emmer and anything with wheat呼罗珊小麦,单粒小麦,二粒小麦等in the title except for buckwheat.以及除荞麦之外的以麦来命名的物质Someone who is following a strict gluten-free diet执行无麦胶蛋白饮食的人must stay away from these grains应该远离这些谷物as they contain gluten.因为它们含有麦胶蛋白This is a flow chart showing这张流程图显示的是where the grains that contain gluten含有麦胶蛋白的谷物fall within the plant kingdom.在植物王国中如何分布Notice they are all grouped注意,虽然被划分为同一种类in the same species so wheat, rye and小麦,黑麦和大麦中含有麦胶蛋白barley contain gluten while rice, corn, teff而水稻,玉米,埃塞俄比亚画眉草buckwheat, quinoa and amaranth are gluten-free.荞麦,藜麦以及苋菜中没有麦胶蛋白Currently the FDA has目前美国食品及药物no definition for gluten free.对无麦胶蛋白还没有明确的定义The proposed definition of gluten is有人建议应该把麦胶蛋白定义为proteins that naturally occur in a prohibited grain在一些谷物中自然存在的蛋白质and that may cause adverse health effects若进入乳糜泻患者体内则会对健康造成in persons with celiac disease不利影响where a prohibited grain would be defined as wheat其中,一些谷物,被定义为小麦,黑麦和大麦rye, barley or cross-bred hybrids of wheat以及这三者的rye or barley.杂交作物For example triticale is a cross between比如,黑小麦就是wheat and rye.黑麦和小麦的杂交产物This labeling is voluntary for those companies这种分类方法由生产whose products meet the definition of gluten-free.无麦胶蛋白食品的公司自由采纳Gluten-free labeling was proposed in 20072007年就有人提出了无麦胶蛋白分类and as of still remains in draft form.的建议,但到年依然还处于筹备状态Because of this lack of labeling it is important因为缺少这种分类for those who have celiac disease所以对于乳糜泻患者来说to carefully labels in order to determine仔细阅读标签确定食品是否whether the food contains gluten or not.含有麦胶蛋白是非常重要的201505/377199
