Synthetic analyses based largely on the platform/inner shelf trilobite faunas suggest that the Chinese eastern Peri-Gondwanan plates and terranes may have belonged to a single biogeographic province during the Tremadocian and the late Katian-Hirnantian, but may be divided into two sub-provinces during the Floian-early Katian (Arenig-Caradoc): One consists of South China, Tarim and Annamia, and the other may include North China, Sibumasu, southern Tibet, Tianshan-Beishan and possibly Hainan.

对这些属于东泛冈瓦纳的中国区块的台地或内陆棚三叶虫动物群的综合分析研究证明，它们在特马豆克期以及凯迪晚期－赫南特期(late Katian-Hirnantian)或阿石极期应归属同一生物地理区，而在弗洛期－凯迪早期(Floian-early Katian)或阿仑尼克期－卡拉多克期(Arenig-Caradoc)则可划分为两个生物地理亚区：一个由华南、塔里木板块和安南或印支地体组成，另一个包括华北板块以及滇缅马、藏南、中天山－北山地体。

Objective To study the antigenpresenting function of splenic dendritic cells in mice after hemorrhage plus closed fracture.Methods Splenic DCs were isolated 24h after hemorrhage plus closed fracture,then the ability to stimulate nonadherent splenocytes proliferation in the presence of conalbumin in vitro was detected,IL12 and IL10 levels in cell supernatants were measured by ELISA kits.
