  • Patent number: 10136078
    Abstract: A random grating based compressive sensing wideband hyperspectral imaging system comprising a front imaging component, an optical splitting component, more than two branches, and a computer, with each branch having an exit pupil transformation component and a compressive spectral imaging component. The system is based on compressive sensing theory, makes use of the correlation between spectra, increases compression rate on the spectral dimension, realizes three-dimensional compressive collection of wideband spectral image data, and greatly reduces data collection amount. The system is capable of measuring spectral image information on a wideband spectrum with a single exposure, and may obtain high spatial resolution and high spectral resolution by means of designing the random gratings on the various spitting paths.

  • Patent number: 9795585
    Abstract: The inventive subject matter relates to the use of L-butylphthalide in the manufacturing of medicaments for the prevention and treatment of cerebral ischemia-induced disease. Cerebral ischemia of the animals or human induces cerebral infarction, neurological deficit, memory disorder, cerebral edema, cerebral apoplexy, metabolic disorder of energy, changes of cerebral blood flow, and the like. The in vivo experiments show that L-butylphthalide can effectively reduce the above-mentioned adverse symptoms induced by cerebral ischemia.

  • Patent number: 8728518
    Abstract: The present invention relates to a novel drug delivery and release system, i.e. Self-emulsifying Drug Delivery System (SEDDS), of butylphthalide, to a preparation process thereof, and to a use thereof in a pharmaceutical formulation. The drug delivery system comprises as essential ingredients 1% to 65% of butylphthalide and 10% to 65% of a emulsifying agent, together with various excipients as required depending on the desired dosage forms. The present invention significantly increases the contact area between butylphthalide and the mucous membrane of the gastrointestinal tract, and therefore improves the absorptivity of the drug.
