Objective:To explore the role and significance of IL-17 on the pathogenesis of rheumatoid arthritis ( RA).Methods:The levels of IL-17 mRNA in peripheral blood mononuclear cell ( PBMC) of 66 RA patients (32 active,34 inactive) and 44 healthy controls were detected by reverse transcription-polymerase chain reaction ( RT-PCR ).The levels of serum IL-17 were detected by enzyme-linked immunosorbent assay ( ELISA).The levels of RF were detected by immunoturbidimetric assay.The correlations of serum IL-17 and RF were analyzed.Results: In RA patients the levels of IL-17 mRNA in PBMC were significantly higher than those in healthy controls ( P＜0.05 ) , but there was no difference between the active and inactive RA ( P>0.05 ).The serum IL-17 levels in active RA patients were significantly higher than those in inactive RA patients and healthy controls ( P＜0.05 ).The levels of serum IL-17 were positively correlated with RF in RA patients.Conclusion: IL-17 and RF play an important role in the pathogenesis and pathology process of RA ,and IL-17 may be associated with RA activity.

As an online and offline mixed teaching method,the"1233"ideological and political teaching reform in Medical Immunology can improve students'independent learning ability,thinking ability,practical ability,ideological and political literacy.It has been piloted on a large scale at Fenyang College of Shanxi Medical University.Moreover,the quality course on the Wisdom Tree online platform has been recognized as the second batch of national first-class quality course.Currently,thirty universities have chosen this quality course.Starting from the actual development of the current"1233"ideological and political teaching reform,this paper uses the SWOT analysis method to systematically analyze the internal advantages and weaknesses,as well as the opportunities and threats of the external competitive environment of the course.Based on this,propose some relevant improvement suggestions and directions,and provide important support for the subsequent optimization and improvement of"1233"ideological and political teaching reform in Medical Immunology.
