The invention provides a circuit and method for detecting power of transmitting signals. The circuit comprises a power detection module and a data processing module. The circuit particularly comprises a down converter, a controllable gain amplifier, an anti-alias filter, an ADC chip, an FPGA and an MCU, wherein the down converter, the controllable gain amplifier, the anti-alias filter, the ADC chip, the FPGA and the MCU are sequentially connected. The method particularly includes the steps that when equipment transmits large signals, the attenuation value of a feedback circuit is increased through adjustment, gains of a link are reduced, saturation of an ADC of the feedback circuit is avoided, and therefore the power of the transmitting signals is accurately measured; when the power of the transmitting signals becomes smaller, the attenuation value of the feedback circuit is reduced through adjustment, the gains of the link are increased, and radio frequency power under the small signal ...

The invention provides construction and application of a low-pH targeting CAR-T cell, and belongs to the technical field of immune targeting therapy. The chimeric antigen receptor (CAR) of the CAR-T cell comprises pHLIP (pH-low polypeptide), and is mainly formed by connecting a CD8 signal peptide, a HiS tag, pHLIP, a CD8 hinge region, a CD8 transmembrane structure region, a 4-1BB costimulatory signal transduction region and intracellular signal regions of CD28 and CD3 zeta in series. The CAR-T cell provided by the invention can realize expression of pHLIP on the CAR-T cell, so that solid tumors are identified in a targeted manner, and the limitation of targeted therapy of traditional tumor markers is avoided.

The invention discloses a signal processing method and a signal processing device applied to a responder and the responder. The method comprises the following steps of: distributing a power signal received by the responder to be a clock frequency signal and a carrier energy signal which conform to a preset proportion, and converting the clock frequency signal into a clock signal; processing the carrier energy signal to obtain a direct current energy signal; and inputting the direct current energy signal and the clock signal to a memory control module of the responder. In the signal processingmethod applied to the responder disclosed by the embodiment of the invention, the problem of increased power consumption brought by the method for generating a clock frequency by using crystal oscillation in the responder in the prior art is solved by adopting a mode of extracting the clock signal from the power signal. The method further solves the problem of increased technical complexity caused by ...
