Abstract
The present disclosure relates to a method for preventing and treating or diagnosing coronavirus infection. SARS-CoV2 lung infection animal models are established using rhesus macaques and human ACE2 transgenic mice, innate immune characteristics that occur in the body in the early stage of SARS-CoV2 infection are explored, and S100A8 protein is found as the root cause initiating the inflammatory storm and becomes an immune indicator for early diagnosis of a patient with SARS-CoV2 infection. Then inhibition of the function of S100A8/S100A9 dimer finally inhibits the virus titer in tissues, thereby decreasing the inflammation level, which proves that a dimer inhibitor can be used as an effective drug for preventing and treating coronavirus infection.

This application provides a data transmission method. The method includes: An electronic device first establishes an MPTCP connection to an application server, where the MPTCP connection includes two TCP connections. Then, the electronic device receives indication information from an application server, where the indication information includes a type identifier and a parameter.
