Historical records show that there are 14 earthquakes of 〉Ms 8 occurring in the two regions, eight of which occurred along the latter tectonic belt. The 2008 Wenchuan earthquake located on both the NS tectonic zone and the Longmenshan fault zone along the eastern margin of the Qinghai-Tibet Plateau.展开更多

The prevalence of siliceous pneumoconiosis was 7.09%, and that over 40 years of age was 21%. The histological findings of lungs from a camel living in that area for 20 years also confirmed to have siliceous pneumoconiosis.展开更多

In primary schools there, only about 20% of the pupils achieve a passing grade for the two basic subjects of Chinese and mathematics, less than one-third of the average local rate. However, this has changed markedly thanks to a bilingual education experiment.展开更多

However, the causative organism has not yet been described in animal hosts. In July 1990, postmortem examinations were made on 59 dogs (Canis familiaris) from the Caotan region of Zhang County. Of them, 6 were found to be infected with the adult worms of Echinococcus multilocularis. The morphological characteristics of the adult were compared in detail with those reported from different parts of China. Our adult specimens were closely resembling those of E. multilocularis reported from Ningxia. The role of domestic dogs in the epidemiology of alveolar echinococcosis in Zhang County was discussed.展开更多
