Synthesized researches on biotic evolution, alternation and accurate chronological dating, taphonomy of vertebrate or invertebrate fossils and elemental or isotopic geochemistry of bones of fossils and sediments, i.e., HBCNOS and COSr, could help us to well understand the biotic and environmental response to the geological events on the Earth surface system and reconstructed the palaeogeography, palaeoecologic environment and palaeoecosystem of the Late Mesozoic, North China.

陆地生物群分布、演化、更替与精确定年，脊椎无脊椎生物埋葬特征，生物演化速率、消长关系和生物群更替的形式和性质，以及脊椎动物骨骼、牙齿的常量、微量元素、H-B-C-N-O-S 和C-O-Sr等地球化学特征的研究可以恢复和重建古地理、古生态环境和古生态系统。

In vertebrate organisms,thesignaling pathway is initiated by the binding of ligandsto the membranousreceptor patchedwhich in turn alleviates the suppression on smoothened,subsequently Smo triggers a series of intracellular events with resultant activation of thezinc-finger transcription effectors,glioma-associated oncogenes(Glil,Gli2,Gli3)transcription factor,which induces the expression of numerous target genes,such as Ptch-1,Hip,Gli1 and Wnt,that regulate proliferation,differentiation.

Hedgehog信号通路是高度保守的调控胚胎组织分化发育的通路，在脊柱动物体内，Hh蛋白与跨膜受体Ptch结合后，解除了Ptch对Smo的抑制，随后Smo从共受体上解离下来进入胞浆，将信号下传并激活锌指转录因子Gli，后者启动Ptch-1、Hip、Gli1、Wnt等目的基因的表达，进而调控细胞的增殖、分化。

As vertebrate genome sequences near completion and research refocuses to their analysis, the issue of effective genome annotation display becomes critical. A mature web tool for rapid and reliable display of any requested portion of the genome at any scale, together with several dozen aligned annotation tracks, is provided at http://genome.ucsc.edu.
