Anagalidae is an important group of the endemic eutherians in the Asian early Cenozoic. It has been sixty years since Simpson(1931) created the family Anagalidae and described the first monotypic genus Anagale (which was later revised by McKenna, 1963). Up to now, there are 13 genera, including 18 species, are assigned to Anagalidae. The earliest member occurs in Early or Middle Paleocene while the last in the Oligocene. Distributed in Guangdong, Jiangxi, hunan, Shaanxi, Anhui, Gansu, Nei Mongol of China and Gashato of Mongolia, the Anagalidae is a group of long continuation and wide distribution although the assignment of some genera may be questionable. The evolution of anagalids is among the essential for understanding of endemic Asian eutherians (Table 1).This paper describes two relatively well-preserved specimens collected in 1990—1991 from the Middle Paleocene of Qianshan Basin, Anhui, which represent two new genera of Anagalidae, and studies the phylogeny of anagalids and emends the family Anagalidae.I thank my graduate advisor, Prof. Li Chuan-kuei for his supervisions and advise, Drs. Wang Yuanqing and Zhu Min, Messrs. Zhang Jie, Xie Shuhua and Li Rongshah, Prof. Yu Ben’ai for their help, and Profs. Tong Yongsheng, huang Xueshi, Zheng Jiajian, and M. C.

The close relatives of Ctenodactylidae were present early in Eocene of Asia. As basal members of early rodents, they are important for us to understand the early history of rodents. In the present paper a new genus and species, Hohomys lii, referred to Youmyidae, and a specirnen of gen. indet., referred to Cocomyidae, are described. They were collected from Yuhuangding Formation near Wangjiazhai Village, Xijiadian Town, Danjiangkou City (formerly Junxian County), hubei. The taxa of the vertebrate fauna associated with these two new ctenodactyloid rodents are Rhombomylus ***, R. sp., Advenimus hubeiensis, A. sp., cf. Heptondon sp.,Asiocoryphodon conicus, Heterocoryphodon flerowi and Zhongvuanus sichuanensis etc., which suggest an age of late Early Eocene.

[Objective] This study aimed to optimize the ultrasonic extraction process of total flavonoids from Angelica keiskei Koidzumi. [Method] Using the yield of total flavonoids as an indicator, the ultrasonic extraction process of total flavonoids from A. keiskei was optimized by orthogonal experimental design. [ Result ] Among four factors in orthogonal experimental design, extraction time exhibited the most significant effect on the extraction result; ethanol concentration exhib- ited a significant effect on the extraction result; ultrasonic power and solid-to-liquid ratio had no significant effect. The optimal conditions for ultrasonic extraction of total flavonoids from A. keiskei were extraction time of 25 min, ethanol concentration of 80%, ultrasonic power of 60 W, solid-to-liquid ratio of 1：20 （g/ml）, under which the yield of total flavonoids reached 1.56%. [ Conclusion] This study provides the basis for further development and utilization of total flavonoids from A. keiskei.

A multituberculate skeleton from the Lower Cretaceous Yixian Formation at Dawangzhangzi, Lingyuan City, Liaoning Province, Northeast China, provides new morphological information for early multituberculates. The specimen is the holotype of Sinobaatar lingyuanensis gen. et sp. nov. It has a narrow skull that lacks the superorbital crest or postorbital process. The dental formula is 3·?·5·2/1·0·3·2. The dental morphology, especially that of cheek teeth, of S. lingyuanensis is similar to that of Eobaatar, which places it in the family Eobaataridae. The postcranial skeleton of Sinobaatar is similar to that of other multituberculates. As in Holotheria, Metatarsal V of Sinobaatar articulates only with the cuboid and has no contact with the calcaneus, which probably represents the primitive condition of multituberculates. Nine carpals of Sinobaatar resemble those of Zhang-heotherium, except the centrale being larger than the trape-zoid. The dental features of Sinobaatar show again that eo-baatarids are

本文选取1998年第一季度-2007年第二季度的数据,运用Johansen协整检验、格兰杰因果检验、向量自回归模型（VAR）、脉冲响应函数和方差分解等多种计量方法,对我国利率途径的货币政策传导机制进行实证分析,研究结果表明,我国利率途径不通畅而不能充分发挥其传导作用,而货币供给量却表现出相对显著的传导效果。本文在此基础上揭示我国应重视对利率传导渠道的完善,并提出应进一步推进利率市场化、企业与金融机构改革、微观主体对利率的敏感性改革的相关政策建议。
