The purpose of this study is to evaluate whether tyrosine kinase receptor Axl affects the dialysis prognosis in chronic hemodialysis patients

It is reported that hemodialysis (HD) patients often develop chronic systemic inflammatoion, and increased inflammatory activity is associated with vascular access failure, cardiovascular disease and death in HD patients. The interaction of Axl and its ligand Gas6 plays an important role in modulating immune response, inhabiting toll-like receptor (TLR) signaling and suppressing inflammatory cytokines production. Thus, we want to investigate the relationship between tyrosine kinase receptor Axl and the dialysis prognosis in HD patients in three-years follow-up.

• patients with chronic infectious disease or acute infection;
• patients with hemodialysis inadequacy;
• the age of patients is older than 65 years or younger than 18 years.
• patients who can not sign an informed consent or disagree to follow up
