Textual research of Wudu earthquake in 186 B.C. in Gansu Province, China and discussion on its causative structure

On the basis of the textual research on the historical earthquake data and the field investigation of Wudu earthquake occurred in 186 B.C., we suggest that the earthquake parameters drawn from the present earthquake catalogs are not definite and amendments should be made. The heavily-damaged area of this earthquake should be located between Jugan township of Wudu County and Pingding township of Zhouqu County. Its epicenter should be in the vicinity of Lianghekou in Wudu County with a magnitude of about 7-7 1/4 and an intensity of about IX-X. The major axis direction of the heavily-damaged area should be in the WNW direction that is approximately consistent with the strike of the middle-east segment of Diebu-Bailongjiang active fault zone, and the origin time should match up to that of the latest paleoearthquake event [before （83±46） B.C.] obtained by the trench investigation. Certain seismic rupture evidences are still preserved on this fault segment. Therefore, we propose on the basis of comprehensive analysis that the causative structure of the M 7-7 1/4 Wudu earthquake in 186 B.C. should be in the middle-east segment of Diebu-Bailongjiang active fault zone.

A Textual Research on Materia Medica of Origin of Orthonym and Synonym of Cuscutae Semen

A textual research on materia medica of origin of orthonym and synonym of Cuscutae Semen and synonym of Nu Luo was conducted in this study,and the trade name,regional synonym and nickname of Cuscutae Semen were reviewed.The records of orthonym and synonym of Cuscutae Semen in the past dynasties,and the first published literature and writing date of orthodox and synonym were summarized.The textual research showed that Nu Luo and Cuscutae Semen were not the same plant,which had positive significance for the identification of the origin and modern application of Cuscutae Semen.

Herbal Textual Research of Inulae Flos in Chinese Classic Prescription

The herbal textual research of Inulae Flos was carried out from the aspects of name,origin,habit and distribution,nature and flavor,meridian,efficacy and indications by referring to ancient Chinese herbal books and different editions of Pharmacopoeia of People’s Republic of China.After textual research,Inulae Flos has been named as"Inulae Flos"since Shennong Bencaojing(Shennong’s Herbal Classic).Its original plant is Inula japonica Thunb.or I.britannica L.,which is easy to multiply and widely distributed.Inulae Flos is used medically with clean and dry capitulum,and there is also honey-burning method.The description of Inulae Flos in Pharmacopoeia of People’s Republic of China,such as nature and flavor,meridian,efficacy and indications,is generally consistent with the records in traditional herbal books.

Historical Evolution of Traditional Medicine in Japan

Traditional Japanese Medicine originated from traditional Chinese medicine and was first introduced to Japan directly from the mainland of China or the Korean Peninsula.After its dissemination,integration,adaption,and development in Japan for generations,it had evolved into Kampo medicine with Japanese characteristics and taken a leading role in Japanese medical practice.In history,there appeared successively schools such as Followers of Later Developments in Medicine,Followers of Classic Methods,Integrated School,and School of Textual Research.Alter Meiji Restoration,Kampo medicine experienced a tremendous impact by western medicine.However after World War II,with unremitting endeavors from learned scholars,traditional Japanese medicinje was revived again.

Textual Research on the Historical Data of the 1573 AD Minxian Earthquake in Gansu Province and Discussion on Its Seismogenic Structure

According to the detailed study of the historical earthquake records and causative structure of the Minxian M6 1/2 earthquake in 1573 A.D., we have found that the most grievous disaster area lies nearby the Minxian county seat （Minzhou county at that time ）. So, we have identified the extremely seismic area of the 1573 A.D. The Minxian M6 1/2 earthquake was located in Minxian city, the intensity of the meizoseismal region is Ⅷ - Ⅳ, the epicenter is 34.4°N, 104.0°E, the location precision is Ⅱ and the deviation of location is less than or equal to 25km. Tectonically, this area lies in the transition region of stress transfer and structural transform between the east Kunlun fault and the northern margin of the west Qiuling fault. The differential activity of the Lintan-Dangchang fault zone is obvious, and only parts of the segment put up Holocene activity. There are landslides and rock bursts of different sizes in the meizoseismal region. By integrated analysis, we conclude that the Minxian-Dangchang segment of the Lintan-Dangchang fault is the seismogenic structure of the 1573 A.D. M6 1/2 Minxian earthquake, in Gansu Province.
