[The correlation of myxovirus resistance 1 and 2'5'-ollgoadenylate synthetase 1 with clinical features of systemic lupus erythematosus].

Objective: To investigate the expression of myxovirus resistance 1(MX1) and 2'5'-oligoadenylate synthetase 1(OAS1) genes in the peripheral blood leukocyte of patients with systemic lupus erythematosus (SLE), and to evaluated the relations between these genes expression levels and disease activity.

Methods: In this study, there were 50 SLE petients, 20 non-SLE patients with rheumatic dieases, and 25 normal controls. The peripheral blood samples of these patients were collected, and the expression levels (indicated as delta Ct value) of MX1 and OAS1 were measured by Sybr green dye based real-time quantitative PCR method.
