Recent advances on genuineness evaluation of Lingnan herbal drugs / 中国中药杂志

Chinese medicine is the traditional treasure of China nation. As the basis of Chinese medicine, traditional Chinese medicine(TCM) plays an important part for the development of Chinese medicine. Genuine medicinal materials with special characteristics of TCM growing in special ecological environment, is recognized as the high quality medicine. Research on genuineness evaluation of TCM is the key to ensure its clinical applications, efficacy and the process of modernization and internationalization for Chinese medicine. Lingnan region of China is situated in the tropical and subtropical zones, where there are rich geothermal and hydrothermal resources. The superior natural and geographic environment of Lingnan has given birth to a variety of native herbal drugs. And treating and preventing diseases with Lingnan herbal drugs has a long story. This study mainly evaluated the genuineness of Lingnan herbal drugs from the aspects of ecological factor, thegenetic information, the history, the culture, the clinical efficacy and the processing, and proposed a new idea to investigate the genuineness of TCM, aiming to provide a scientific basis for genuineness evaluation.

Ecological developmental characteristics of rats in the epidemic areas of hemorrhagic fever with renal syndrome in Huangdao District of Qingdao City, Shandong Province / 中华地方病学杂志

Objective To understand the ecological developmental characteristics of rats in the epidemic areas of hemorrhagic fever with renal syndrome (HFRS) so as to provide a basis for effective control of HFRS.Methods Based on the China National Disease Surveillance Reporting and Management System,data of HFRS cases from 2010 to 2014 were collected and analyzed by retrospective analysis.Meanwhile surveillance data of rats were collected and the capture rates in different seasons,genders and districts were also analyzed.Results Totally 51,92,129,85 and 71 cases of HFRS were reported from 2010 to 2014.Most HFRS cases occurred from October to November which were 43,59,78,37 and 37,respectively.Totally 2902 rats were captured from 2010 to 2014.The five-year average capture rate was 4.87％ (2902/59610).The highest capture rate was 6.94％ (910/13107) in the third quarter and the outdoor capture rate (5.80％,1681/28987) was higher than that of indoor(3.99％,1221/30623,x2 =324.35,P ＜ 0.05).More male rats were captured than female rats and the overall proportion was 62.82％ (348/554) and 37.18％ (206/554),respectively.The outdoor rats were mainly Apodemus agrarius (556),Cricetulus triton (432),Rattus noruegicus (217),Mus musculus (211) and Sorex araneus (139),and the indoor rats were mainly Mus musculus (514),Rattus noruegicus (469) and Sorex araneus (181).The black rat disappeared and White-bellied rat appeared.Conclusions The rat density keeps higher all year round and the type of rats has become increasingly complex.Mixed living of indoor and outdoor rats increased the infection probability of different types of Hantavirus,which has an immediate impact on the spreading pattern of HFRS.
