History evolution on processing technology and modern research of Polygonatum cyrtonema in Jiuhua Mountain / 中草药

Polygonatum cyrtonema, which is growing in Jiuhua Mountain, is genuine medicinal materials. The main processing methods of it are cutting, single-steamed, re-steamed, nine times steamed and nine times shined, wine-steamed, wine-stewed, copying and so on. Its effective components are polysaccharides and steroidal saponins, and they also have pharmacological activities such as anti-oxidation, regulating immunity, lowering blood sugar, antitumor, antibiosis, and antiviral. The development history and modern research progress of processing technology of P. cyrtonema in Jiuhua Mountain were summarized, which provides reference and basis for its processing research and lays the foundation for its standard operation rules of GMP processing.

Diversity and distribution of host animal species of hantavirus and risk to human health in Jiuhua mountain area, China.

OBJECTIVE: To investigate the diversity and the distribution of host animal species of hantavirus and the effect on human health in Jiuhua Mountain area, China. METHODS: The host animal species of hantavirus was surveyed by using the trap method and the species diversity was evaluated by using the Simpson, Shannon-Weaner, and Pielou indices. Hantavirus antigens or antibodies in lung and blood samples of all the captured host animals were detected by direct or indirect immunofluorescence. RESULTS: Nine animal species of hantavirus were distributed in the forest ecosystem of Jiuhua Mountain. Of these, Niviventer confucianus and Apodemus agrarius were predominant, and N. confucianus, Rattus norvegicus, and Mus musculus had relatively large niche breadth index values. The host animals in the eastern and western mountain regions shared similar biodiversity index characteristics, predominant species, and species structures. Hantavirus was detected in 5 host animal species in Jiuhua Mountain area, the carriage rate of hantavirus was 6.03%. The average density of host animals in forest areas of the mountainous area was only 2.20%, and the virus infection rate in the healthy population was 2.33%. CONCLUSION: The circulation of hantavirus was low in the forest areas of Jiuhua Mountain and did not pose a threat to human health.
