The method includes: shooting a cone-shaped group of viewing-frustum rays from a target character object for a hit object in a three-dimensional scene picture; determining object attribute information of the hit object based on an interaction between the viewing-frustum rays and the hit object; performing vector conversion on the object attribute information of the hit object, to obtain a ray-feature vector; collecting, by using a location of the target character object as a collection center, a plurality of height-value matrices corresponding to different granularities; performing feature dimension reduction on the height-value matrix corresponding to each granularity, to obtain a height-map feature vector; and integrating the ray-feature vector and the height-map feature vector into a three-dimensional scene feature.

[Weiwei LIU, Lufan WANG, Zhifeng GUO, Junsong MAO, Chenyang GAO, Yuanrui TIAN, Zhen GU, Xiaoxi LIU] CN Shanghai The present invention provides a mRNA composition for microneedle administration and its application. The composition includes an aqueous phase solution and a lipid solution, wherein the lipid solution encapsulates the substance in the aqueous phase solution to form lipid nanoparticles (LNPs), and the aqueous phase solution includes mRNA encoding the corresponding protein and a buffer. It was found that an improved buffer pH could substantially increase the drug loading capacity of LNPs, and reduce the use level of composition and excipients and the dose for microneedle administration with less toxic side effects and better therapeutic effects, and the microneedle administration technology could achieve increased effective expression, decreased expression in the liver, and prolonged in vivo expression of mRNA composition, and increased antibody titer in response to low-dose mRNA in vivo. The present invention really realizes microneedle intradermal administration of mRNA composition. The composition for microneedle intradermal administration enables stable long-term storage, and has a potential application prospect of reducing toxicity and increasing efficacy.
