This invention provides a multi-to-multi drug screening method for CRISPRa / i GPCR libraries based on a three-dimensional spatial hybrid screening model and its applications, belonging to the field of biomedical technology. The method includes the following steps: Step (1): Constructing a screening cell pool; Step (2): Classifying the drugs to be screened; Step (3): Constructing a drug hybrid screening model; Step (4): Grouping drugs according to mutually perpendicular X, Y, and Z planes, with drugs in each plane mixed to form independent pools; Step (5): Processing each pool into a cell pool; Step (6): Detecting and analyzing the changes in sgRNA abundance in each pool; Step (7): Decoding to determine the drug-GPCR interaction pairs. This invention offers higher screening throughput, realizes a multi-target, multi-drug screening mode, reduces costs and time, and enables large-scale research on drug-gene interaction networks, which is of great significance for drug research and development.

The application discloses a high-perturbation gene priority ranking system, which comprises a gene interaction network, a hub gene identification module, a knockout perturbation initialization module and a perturbation propagation network.
