BACKGROUND Increased platelet aggregation is implicated in the pathogenesis of ischemic stroke and anti-platelet strategy may contribute to its therapy. Panaxatriol saponin (PTS), the main components extracted from Panax notoginseng, has been shown to be efficacious in the prevention and treatment of ischemic stroke in China. The aim of this study is to… (More)
Nonlinear conjugate gradient method is very popular in solving large-scale unconstrained minimization problems due to its simple iterative form and lower storage requirement. In the recent years, it was successfully extended to solve higher-dimension monotone nonlinear equations. Nevertheless, the research activities on conjugate gradient method in… (More)
BACKGROUND Pinelliae Rhizoma is a commonly used Chinese herb which will change brown during the natural drying process. However, sulfur fumed Pinelliae Rhizoma will get a better appearance than naturally dried one. Sulfur fumed Pinelliae Rhizoma is potentially toxical due to sulfur dioxide and sulfites formed during the fuming procedures. The odor… (More)
Panaxatriol saponins (PTS), the main components extracted from Panax notoginseng, have been shown to be efficacious in the prevention and treatment of cerebrovascular diseases in China. NF-E2-related factor 2 (Nrf2), a transcription factor regulating antioxidant and cytoprotective responses to oxidative stress, has received particular attention as a… (More)
Herbalogical textual study indicated "Guanzhong" recorded in Bencaojing at Han Dynasty had pteridophyte characters. In the period of Wei and Jin Dynasties, the name of "Guanzhong" was really belonged to spermatophyte. Since Southern and Northern Dynasties, fern has been the main source of "Guanzhong" in which Woowardia japonica was used longer than others.
