The invention belongs to the technical field of cellular immunotherapy, and particularly relates to a targeted FAP chimeric antigen receptor macrophage as well as a preparation method and application thereof. According to the invention, FAP is taken as a target spot to design a CAR carrier of a specific targeted activated hepatic stellate cell, and a CAR-M cell for treating hepatic fibrosis is constructed. The macrophage expressing the chimeric antigen receptor has a remarkable killing effect on FAP positive cells, and a new thought is provided for clinical treatment of hepatic fibrosis, liver cirrhosis and liver cancer.

The application relates to a DSFP radio frequency connector, which comprises a terminal unit and a shielding piece inserted into the terminal unit. The application reduces the crosstalk between the signals transmitted by the DSFP radio frequency connector through the following modes: the ground terminal of the terminal unit adopts a double-contact structure to contact the circuit board, the shielding piece is arranged between the terminal units and contacts the inner side of the accommodating groove of the circuit board, and the DSFP radio frequency connector is fixed to the printed circuit board through three welding legs of the shielding piece. The DSFP radio frequency connector has good high-speed transmission efficiency, can replace the common radio frequency connector in small base stations, and reduces the cost. In addition, the shielding piece of the DSFP radio frequency connector contacts the inner side of the accommodating groove of the circuit board through a double-contact structure, and the resonance problem caused by single-point contact can be avoided.

This application discloses a transmission gearbox and a power tool. The transmission gearbox includes a gearbox housing, a gear transmission module, and an intermediate section. The gearbox housing includes a first gearbox housing and a second gearbox housing. The gear transmission module includes a first gear reduction assembly housed in the first gearbox housing and a second gear reduction assembly housed in the second gearbox housing. The first gear reduction assembly drives the second gear reduction assembly for output. The first gear reduction assembly includes a transmission internal gear ring. The intermediate section axially separates the first gear reduction assembly and the second gear reduction assembly. The intermediate section includes an anti-rotation part integrally formed with the gearbox housing and a support part at least partially integrally formed with the gearbox housing. The transmission internal gear ring is axially moved to engage or disengage from the anti-rotation part to switch the speed of the first gear reduction assembly. The support part supports the second gear reduction assembly to prevent the axial force of the second gear reduction assembly from being transmitted to the anti-rotation part. The support part is located at the end of the first gearbox housing and is disposed opposite to the second gearbox housing. The anti-rotation part has multiple stop teeth and multiple matching grooves located between adjacent stop teeth in the circumferential direction. The central angle of adjacent matching grooves is less than or equal to 30°.

This application discloses a vibrating and unblocking screen device for flour sieving. The vibrating and unblocking screen device includes: a base with a mounting bracket; a sieving assembly mounted on the mounting bracket, the sieving assembly including a screen body and a screen mesh, the screen body being movably mounted on the mounting bracket, and the screen mesh being rotatably mounted on the screen body; and a cleaning assembly fixedly mounted on the screen body and close to the screen mesh, which can clean and unblock the screen mesh. The advantages of this invention are its ease of use and high sieving efficiency.
