A. phagocytophilum infection has been reported in I. persulcatus and engorged D. silvarum ticks in northeastern China (3). In this study, we also found Haemaphysalis spp. ticks, including H. longicornis and H. concinna ticks, to be infected by the agent. This fi nding indicates that various tick species may be involved in the maintenance and transmission of(More)
AIM To investigate the roles of c-Jun N-terminal kinase (JNK) signaling pathway in vitamin E succinate-induced apoptosis in human gastric cancer SGC-7901 cells. METHODS Human gastric cancer cell lines (SGC-7901) were treated with vitamin E succinate (VES) at 5, 10, 20 mg/L. Succinic acid and vitamin E were used as vehicle controls and condition medium(More)
OBJECTIVE In order to investigate the roles of mitochondria in vitamin E succinate (VES)-induced apoptosis in human gastric cancer SGC-7901 cells. METHODS Mitochondrial transmembrane potential (deltapsi(m)) was observed by confocal laser scanning microscopy, while the expression of cytochrome c in cytosol and caspase-3 was measured by western blotting(More)
OBJECTIVE To study the biological characteristics of natural reservoirs of Yesinia (Y.) pestis in China. METHODS Species and genera of natural reservoirs of Y. pestis in China and their faunal distribution were characterized with modern taxonomic techniques. The ecological roles of natural reservoirs of Y. pestis in the natural plague foci were determined(More)
BACKGROUND China experienced an unprecedented outbreak of dengue fever in 2014, the National Health and Family Planning Commission of the People's Republic of China (NHFPC) carried out a series of supervision work on integrated vector management (IVM), and Chinese Center for Disease Control and Prevention (China CDC) conducted a rapid detection on vector(More)
We performed genetic analysis of Bartonella isolates from rodent populations from Heixiazi Island in northeast China. Animals were captured at four sites representing grassland and brushwood habitats in 2011 and examined for the prevalence and genetic diversity of Bartonella species, their relationship to their hosts, and geographic distribution. A high(More)
OBJECTIVE To group and characterize natural plague foci in China. METHODS A novel two-class typing method as well as a three-indication nomenclature method were established to group and characterize the natural plague foci, on the basis of eco-geographical landscapes of plague foci, genetics of Yersinia pestis, zoology of rodent reservoirs and the(More)
