Based on statistical analysis of 3 863 specimens identified in 10 samples from Hantaichuan, Nianpanlianggou and Liugou sections, the sporo-pollen assemblage from the Yan'an Formation in Dongsheng region was established, which is generally characterized by the slight dominance of gymnospermous pollen grains (generally attaining proportion of 51%-54%), whereas the pteridophytic spores reach 46%-49% in abundance. In comparison with those of adjacent regions as well as Eurasia and North America, the present sporo-pollen assemblage is regarded to early Middle Jurassic (corresponding to Bajocian Stage) in geological age. According to the climatic conditions reflected by the palynoflora, the paleoclimate in Dongsheng region is suggested to be warm temperate or subtropical warm and humid during the early Middle Jurassic.展开更多

文摘“气”作为中医学特有概念的出现,对中医学术理论体系的建立具有划时代意义。对气本质的认识应从古人对气功能的原始论述中去探讨,与西医学的神经、内分泌、免疫功能具有高度相关性。气络与神经—内分泌—免疫网络(NEI 网络)在多维立体网络系统、生命运动的稳态机制、整体系统的生命观、生命运动的功能状态研究、符合生物—心理—社会医学模式的转变等共性特征方面高度相似,揭示气络与 NEI 网络具有高度相关性和内在一致性。由此提出“气络—NEI 网络”的概念,对应用中西医两种医学从宏观整体和微观领域认识生命现象及把握疾病的发生发展和演变规律,指导现代多种疑难性疾病的诊断治疗,研究络脉及络病理论具有重要意义。
