AIM: To observe the efficacy of ketosteril in treatm en t of chronic renal failure with high level of plasma Cys-C. METHODS: 60 patients with chronic renal failure were randomly divided into treatmen t group and control group. The control group was adopted a low protein and low p hosphorum diet and correcting symptoms; the treatment group, based on the therap y of the control group, was given ketosteril; 30 healthy subjects were used as t he normal control to observe changes of Cys-C, Scr, TC, HB, and HDL before and after the treatment. RESULTS: The levels of Cys-C and Scr decre ased after the administration of ketosteril (P

Type I interferons play an important role in the pathogenesis of autoimmune diseases such as systemic lupus erythematosus(SLE).Monoclonal antibody shows therapeutic potential by blocking the signaling pathway.This study used recombinant human subunit 1 of the type I interferon receptor(IFNAR1)protein to immunize New Zealand white rabbits,and applied B cell cloning technology to screen and obtain rabbit parental antibodies.After humanization modification,QX006N was obtained.In vitro biological studies showed that QX006N could specifically bind to human IFNAR1 with an affinity of 108 pmol/L,and neutralize the type I interferon signaling pathway and this pathway mediated biological effects.This study provides a solid foundation for the development of antibody drugs targeting the type I interferon signaling pathway for the treatment of SLE.
