Abstract: A composition gel for surgical efficiency improvement of urinary stone lithotripsy and stone fragments removal in renal collecting system includes component A and component B. The component A contains fibrinogen and fibrin stabilizing factors. The component B contains thrombin. Moreover, at least one of the components A and B contains Ca2+, plasminogen and a coloring agent. The composition gel may quickly form plasminogen-containing fibrin gel with color, and certain toughness and plasticity in urine and normal saline environments, may adhere to and wrap stone fragments in such environments, and is removed by negative pressure suction and/or stone basket. The composition gel is suitable for efficiently removing stone fragments which remain after lithotripsy and are unable to be removed by an effective method at present. It has good biosafety, and achieves stone clearance rate of more than 85% without damage to the kidney and surgical instruments.

Abstract: A liquid crystal display is configured such that a composite layer thereof is transparent to incident light in one voltage condition (e.g., in the absence of an applied voltage) and scatters incident light out of the display in another voltage condition (e.g., when a voltage is applied). The liquid crystal display does not need polarizers or color filters.

Abstract: This invention discloses a liquid crystal display (LCD) device and a method of manufacturing the same. The LCD device comprises a first substrate and a second substrate opposing each other, and a nematic liquid crystal layer disposed therebetween and comprising a nematic liquid crystal and a polymer network. The polymer network is formed by irradiation polymerization of a functional monomer in a nematic liquid crystal mixture. The polymer network can reduce the scattering phenomena caused by the refractive index mismatch between liquid crystal and polymer in the prior LCD devices and significantly reduce the dark-state light leakage, so that the contrast is improved. Moreover, since there is no polymer projection disposed on the alignment layer according to the invention, the dark-state light leakage caused by polymer projections is avoided and thus the contrast is further improved.
