The present invention provides a method for sequencing a nucleic acid using an immersion reaction protocol. The immersion reaction protocol comprises sequentially immersing a solid support having nucleic acid molecules immobilized thereon in different reaction containers to realize nucleic acid sequencing. FIG. 1 is published together with the abstract

Button cell and electronic device

The present disclosure provides a button cell and an electronic device. In the button cell, a conductive member covers an opening of a top cover, and the top cover is connected to the conductive member. A cell is placed in an accommodating cavity of a bottom shell. A first tab is welded to an inner bottom wall of the bottom shell, and then the top cover having the conductive member is connected to the bottom shell in a sealed manner, with a second tab on the cell being electrically connected to the conductive member. Finally, an electrolyte solution is injected into the accommodating cavity. After the electrolyte solution is injected, a sealing member covers the liquid injection port, and the sealing member is connected to the liquid injection port in a sealed manner.

Models and methods for rapid screening the efficacy of immunoregulating drugs

The present invention provides a model and method for rapid screening the efficacy of immunoregulatory drugs. The method comprises constructing an animal model containing PVDF capsule tubes, and further comprises analyzing the pharmacodynamic data for the animal model in vivo, phenotype identification by paired flow cytometry and multi-omics data. The PVDF capsule tubes have cells comprising tumor cells and immune cells in a single cell suspension; wherein the tumor cells and immune cells are derived from fresh tumor tissues or body fluids of clinical patients. The animal model constructed according to the present invention can be used for immune system targeting and drug efficacy regulation screening, and drug screening for multiple patients at the same time. It provides a rapid and effective method and model for clinical precision medicine and new drug development.

Packet transmission method, apparatus and system, network device, and storage medium

This application discloses a packet transmission method, apparatus, and system, a network device, and a storage medium, and relates to the field of communication technologies. The method includes: A first network device receives an IP packet, and adds indication information to the IP packet and sends the IP packet. The indication information indicates to add processing information to an error packet corresponding to the IP packet. The processing information indicates a manner for processing the error packet. The error packet is generated by a second network device when the IP packet reaches a corresponding maximum hop count. According to the method, the processing information indicating the manner for processing the error packet can be carried in the error packet corresponding to the IP packet, so that the first network device can process the error packet based on the processing information.
