Abstract: The disclosure provides a mesenchymal stem cell (MSC) over-expressing CXCR5, preparation method and use thereof. Overexpression of CXCR5 can allow directed migration of MSCCXCR5 to an inflammation area in vivo so as to play a role in immunomodulation but not make MSCCXCR5 randomly scattered at various parts in a body. Treatment of diseases using the mesenchymal stem cells will have more targeting and effectiveness, and will effectively improve the treatment effect of MSC.

Abstract: A method of sending cell measurement configuration information and a device thereof, and a method of receiving cell measurement configuration information and a device thereof are provided. The method of sending cell measurement configuration information includes: sending, by a network device through a dedicated signaling, to a terminal first measurement configuration information used by the terminal, where the first measurement configuration information includes cell change configuration information and indication information configured to identify the cell change configuration information; sending, by the network device, second measurement configuration information through a system broadcast message, where the second measurement configuration information includes cell change configuration indication information.

Abstract: Provided are a method and device for detecting signal strength. The method comprises: receiving measurement configuration information and report configuration information about received signal strength indication (RSSI) measurement issued by a network side; conducting RSSI measurement according to the measurement configuration information to obtain an RSSI sample value; and according to the report configuration information, processing the RSSI sample value to obtain a report value of the RSSI measurement, and reporting the report value of the RSSI measurement to the network side.

Abstract: An answer information feedback method includes steps of: with respect to a current uplink subframe of a primary carrier in a TDD mode, determining, by a terminal, a downlink subframe of a secondary carrier in an SDL mode and corresponding to the current uplink subframe in answer information feedback as a to-be-fed-back downlink subframe, the to-be-fed-back downlink subframe being determined from designated downlink subframes of the secondary carrier in accordance with a downlink retransmission timing mode for a DL-reference UL/DL configuration of the secondary carrier, the designated downlink subframes including downlink subframes except a downlink subframe having a location identical to an uplink subframe indicated by the DL-reference UL/DL configuration, the DL-reference UL/DL configuration being identical to a timeslot configuration of the primary carrier; and transmitting answer information for the to-be-fed-back downlink subframe to a network side using the current uplink subframe.

Abstract: Disclosed is a solid state biological reaction device, comprising a main tank (1), wherein the device further comprises a support (2) supporting the main tank (1), and the support (2) makes the main tank (1) be rotational in the horizontal position, and be statically cultured in the vertical position. The device is relatively simple, in particular, the mixing of materials uses the method of a vehicle-tank in combination with rotation, achieving the tank free conversion between the two different poses of vertical and the horizontal; and the device conducts the work of loading, inoculation, cultivation and transplantation and so on in the upright pose, and completes the work of sterilization and mixing of materials and so on in the horizontal pose. The device is not only quick to use and easy to move, but also omits the stirring system which occupies a lot of manufacturing costs, and is easy to use in large-scale production.

Abstract: A solid-state biological reaction device, comprising a main tank body and a collector is provided. A top air outlet, a bottom air inlet and a material entrance and exit are provided on the main tank body. The collector is connected to the main tank body through the top air outlet. Also provided is a method for preparing filamentous fungus spores utilizing the solid-state biological reaction device, comprising the steps of: feeding a culture substrate into the main tank body through the material entrance and exit, performing steam sterilization by injecting steam through the bottom air inlet, inoculating the filamentous fungus strains onto a sterile culture substrate in the main tank body for culturing so as to obtain mature filamentous fungus spores, and then passing dry air into the main tank body through the bottom air inlet, so that the filamentous fungus spores enter the collector through the top air outlet.
