摘要:
Use of a racemate of pinocembrin, a racemate of pinocembrin salt, a racemate of pinocembrin precursor or a racemate of pinocembrin hydrate in manufacture of a medicament for prophylaxis and treatment of stroke. Particularly, use of pinocembrin racemate in manufacture of a medicament for treatment of acute ischemic stroke.
摘要:
Inclusion complexes of pinocembrin with cyclodextrin or its derivatives and their preparation are provided. The inclusion complexes can be used to make drugs.

摘要:
The present invention relates to a method for resolution of a mixture of pinocembrin optical isomers, in particular a pinocembrin racemate, using a chiral primary amine or a chiral sulfinamide. The present invention also relates to a (R)-(+)-pinocembrin obtained by the method.

摘要:
Two crystalline forms of pinocembrin of formula (I): α and β, their preparation and their use for manufacture of pharmaceutical compositions. There exists difference between them in bioavailability. They are used for treating and preventing cerebral ischemic diseases by protective action of neurovascular unit, and enhancing blood drug level in vivo.

摘要:
The use of extract form Wangla (coeloglossum viride (L) Hartm. Var. Bracteatum (Willd.) Richter), succinate derivative esters, and a derivative and pharmaceutical acceptable salts thereof, for the manufacture of a pharmaceutical preparation for the treatment of dementia, particularly for the treatment of Alzheimer' disease and Vascular dementia. Through Animal experiment, it has been demonstrated that, succinate derivative esters can improve learning and memory ability in dementia rats induced by scopolamine and cyclohexenyl imine; improve learning and memory ability in dementia rats induced by β-amyloid; improve learning and memory ability in dementia rats induced by permanent ligation of bilateral carotid; and improve memory ability of normal animals. It has the advantage of high activity, low toxicity and no inhibition to cholinesterase.

摘要:
The present invention discloses a method for improving channel transmission efficiency in a wireless network. In the course of data transmission, a length of a data frame split from a Media Access Control (MAC) layer service data packet is changed in real-time according to a channel state of the wireless network. The inventive method for improving channel transmission efficiency in a wireless network can effectively improve the efficiency of wireless channel data transmissions and can be easily implemented.
