Abstract: A pharmaceutic composition for treating an allergic skin disorder. It has an active component and a carrier. The active component has a major active ingredient osthol and a group of minor active ingredients: xanthotoxol, xanthotoxin, isopimpinellin, bergapten, and imperatorine. The major active ingredient osthol accounts for at least 90% by weight of the active component, which accounts for 5-35% by weight of the overall pharmaceutic composition.

Abstract: For a terminal located in any area of a first cell in a first system, a sum of actual interference of all second cells to any spectrum resource to be used by the terminal can be determined according to a pre-established interference matrix for representing historical reference interference of each second cell in a second system to each area in the first cell and a spectrum resource real-time occupation status of each second cell; when it is determined that the sum does not exceed a preset interference threshold value range, it is determined that the terminal can use the any spectrum resource; or when it is determined that the sum exceeds a preset interference threshold value range, it is determined that the terminal cannot use the any spectrum resource.

Abstract: The present invention is applicable to the field of mobile terminals and provides an antenna switching system and method. The antenna switching system includes a radio-frequency transceiver circuit, a primary antenna, and a parasitic antenna, where the primary antenna is connected to the radio-frequency transceiver circuit, and further includes a switch circuit, configured to connect, when the parasitic antenna is used to receive or send a radio-frequency signal, the parasitic antenna and the radio-frequency transceiver circuit. If the parasitic antenna is grounded, the parasitic antenna may be configured to spread a spectrum. In addition, when carrier aggregation is needed, the parasitic antenna is connected to the radio-frequency transceiver circuit, so as to become an independent receive or transmit antenna.
