Abstract: The present disclosure provides a biomarker for detecting lung cancer and use thereof. A proteomics method is used to analyze a protein with significant differences in blood of a patient with lung cancer and normal people, such that a series of biomarkers capable of early predicting an occurrence risk of lung cancer are screened out, a group of biomarkers are further screened to construct a diagnosis model for lung cancer, and the model may be used for conveniently, non-invasively and effectively predicting whether an individual suffers from lung cancer or not, and meets clinical needs.

Abstract: Embodiments of the present invention provide a method for implementing a heartbeat service of a high availability cluster, including: writing, by a server, heartbeat counting information to a disk array, where the heartbeat counting information includes a write heartbeat message sequence number, a read peer heartbeat message sequence number, active-standby state information, a heartbeat message, and a heartbeat message length of the server, so that one or more corresponding servers read the heartbeat counting information, in the disk array, of the server; and reading heartbeat counting information, which is written by the one or more corresponding servers to the disk array, of the one or more corresponding servers, and repeating the write operation and the read operation. Correspondingly, the embodiments of the present invention further provide a server, which solves a spit-brain problem, and improves data security.
