A human skull, buried about 2500 years ago in a Bronze Age cemetery at Jinggouzi, a site of an important ethnic group in ancient China, appeared to have characteristics of fibrous dysplasia. The CT images indicated a reduction in bone density and relatively homogeneous lesions. More features were revealed using CT reconstruction techniques. Lesions seen in low‐magnification images using a 3D deep‐field microscope had an irregular honeycomb‐like structure. At higher magnification, the trabeculae morphology and the gaps between the trabeculae were irregular and varied in size and shape. Paraffin‐embedded specimens stained with HE showed trabeculae with tortuous irregular arrangements varying in shape and width. The irregular trabeculae of woven bone has been described as having fibrous dysplasia. Molecular analysis of the GNAS gene indicated no mutation. This provides a non‐invasive approach for us to make more comprehensive diagnoses and to assist research into ancient human diseases. 相似文献

The provenance of more than 2200-year-old terracotta warriors and horses in the Qin Shihuang Mausoleum is still a mystery, even though some researchers have inferred that the terracotta figures were produced near the mausoleum. The sporomorphs (pollen and spores) extracted from terracotta fragments of a warrior and a horse and compared with those obtained from soil samples from the Qin Dynasty layer in Pit No. 2 of the Qin Shihuang Mausoleum indicate that the pollen spectrum from the terracotta horse is different from that of the warrior, but similar to the local soil samples. Herbaceous pollen was dominant in the warrior sample, while arboreal pollen predominates in the horse and soil samples. Palynological evidence suggests that the terracotta horses were produced at a locality near the mausoleum, while the warrior came from a site which was further afield. 相似文献

自来水的出现对近代城市的影响是巨大的,它改变了城市的空间结构,促进了城市市政体系的形成。天津作为一个商埠城市,租界的存在和城市行政的分割,使得水供给逐渐形成两大系统。不同的社会环境和市政制度,使自来水以不同的方式被城市社会接受。在租界,自来水的供给是近代化社区形成的基础,在老城区,自来水的传入更多表现出传统与新生活方式之间的冲突与交融。然而无论如何,从清末到民国时期,伴随着自来水进入人们的生活,健康、卫生等新的观念逐步被接受,近代城市生活方式逐渐形成。 相似文献

冀北地区是中国北方青铜文化的一个重要分布区,也是北方文化和中原文化的交错地带,其文化遗存非常丰富,尤其是东周时期的青铜短剑遗存最为集中,而且文化因素极其复杂。本文在对该地区发现的青铜短剑进行类型学分析的基础上,结合前人的研究成果,试图揭示这些复杂的文化面貌中所含的各种文化因素。 相似文献

新石器时代,南北陶器装饰已出现不同面貌,大体说来,黄河中上游为一种,表现为彩绘的样式:长江中游为一种,表现出素面刻划的特征。造成差异的原因,地理资源即无机质矿物颜料的多寡是第一位的,这一推论大体符合彩陶分布状况,和历史献记载以及现代探矿资料。 相似文献

咸丰年间,清政府为了解决财政上的困难,发行了大清官票和大清宝钞,但由于发行过滥,造成通货膨胀、纸币贬值,引起百姓的不满和抵制,不得不于同治年间停止了纸币的制造和发行。本文介绍了河北大学博物馆收藏的几件清代官票和宝钞。 相似文献
