Abstract: A method for the site-directed integration of a target gene into a specific site of an immune cell and a use thereof, in particular being a method for the site-directed integration of a target gene (such as a CAR gene) into a specific site of an immune cell (such as HPK1) based on a non-viral vector, and a use thereof. The method completes gene knockout and target gene introduction in one step, and prepares a cell that has undergone gene knockout at a specific site and that stably expresses a target gene. Moreover, the method has the characteristics of simple preparation, low costs, stable expression, and stable function, and does not affect the gene characteristics of a cell. In addition, the obtained cell has high killing efficiency and strong infiltration capability.

Abstract: Techniques for data replication involve determining, based on a metadata log, whether an overlap exists between a target input/output operation or target IO and previous IOs, wherein the metadata log records metadata related to data replication. Such techniques further involve writing the target IO to a source data volume according to a determination that no overlap exists between the target IO and the previous IOs. Such techniques further involve replicating data within the range of the overlap from the source data volume to a data log according to a determination that the overlap exists between the target IO and the previous IOs, and writing the target IO to the source data volume after completion of the replicating. Such techniques further involve replicating the target IO to a target data volume based on the metadata log and the data log.

Abstract: Techniques manage application systems in an application environment. The application environment includes a first application system, a second application system and a third application system. First snapshot information of a first group of snapshots of the first application system is obtained, the first application system being in active state. Second snapshot information of a second group of snapshots of the second application system is obtained, the second application system being in standby state. It is determined whether the second application system and the third application system have a common snapshot based on the first snapshot information and the second snapshot information. Data is synchronized to the third application system depending on whether the second application system and the third application system have a common snapshot. Overheads required during data synchronization may be reduced as far as possible, and the efficiency of data synchronization may be improved.
