Abstract: A use of THP (Pirarubicin) in preparation of a medicament for enhancing antitumor efficacy of V?9V?2 T cells is provided. It is discovered that a surface marker MIC A/B of tumor cells treated with THP is significantly enhanced, and THP-induced tumor cells enable V?9V?2 T cells to highly express NKG2D. An NKG2D/MIC A/B pathway is a classical pathway through which V?9V?2 T cells exert a killing effect. THP significantly enhances an ability of V?9V?2 T cells to kill hepatocellular carcinoma cells through regulating the NKG2D/MIC A/B pathway, and provides a new therapeutic solution for TACE (transcatheter arterial chemoembolization) surgical treatment of clinical cancer patients.

Abstract: A titanium-based composite catalyst for polyester synthesis, preparation method and application thereof are provided. The preparation method is: preparing a titanium-silicon catalyst precursor first, adding the titanium-silicon catalyst precursor to a biochar material in a certain mass ratio and mixing evenly, and aging, drying, calcining and wet grinding to obtain a titanium-silicon composite catalyst, and then mixing the titanium-silicon composite catalyst and a phosphate ester with a mass ratio of 1:(0.001-0.5) to obtain the titanium-based composite catalyst. The titanium-based composite catalyst is composed of the phosphate ester and the titanium-silicon composite catalyst, wherein the phosphate ester is adsorbed and wrapped on the surface of the titanium-silicon composite catalyst; the phosphate ester is combined with a titanium-silicon catalyst in the titanium-silicon composite catalyst by van der Waals force.

Abstract: The invention discloses a method for realizing an arbitrary ultrasonic field. The method uses a pulsed laser generated by a pulsed laser machine, modulated into a specific two-dimensional or three-dimensional light field distribution by a phase-type spatial light modulator, and the specific distribution of light acts on photoacoustic media. Due to the photoacoustic effect, a sound field distribution corresponding to the light field will be generated in the photoacoustic medium. The sound field constitutes a two-dimensional or three-dimensional spatial sound source. The sound waves emitted by the sound source are transmitted through a certain distance. The expected ultrasonic field distribution can be formed on a surface or inside of samples. The invention can transform the coherent ultrasonic field distribution formed on the surface or inside of the target object, simply by adjusting the phase distribution diagram input to the spatial light modulator, which has great flexibility.
