Patients will be chosen according to the inclusion and exclusion standard and written informed consent will be obtained from all participants.
Exit criteria: During the research, for his / her own consideration or at the request of the investigator the patient may withdraw from the trial at any time. For each subject who withdrew from the trial, the investigator must detail the subject's exit date, the reason, and other information in case report form(CRF).

exosomal miRNAs in serum samples
Periodo de tiempo: samples will be collected every 12 months later until 5 years
|
In discovery set, miRNA sequencing of serum exosomes will be performed for each sample.
Data will be analyzed using statistical methods.
Potential miRNAs that show group-differentiation will be selected in combination with information and test results.Based on these selected miRNAs, the same assays will be repeated on all validation set samples to screen out significant miRNA.
