Abstract:
Objective To investigate the relation of synovial anti-citrullinated epitope peptide(CCP)expression and peptidyl arginine deiminase 4 (PADI4)gene in the rheumatoid arthritis patient.Methods From February 2013 to 2015 in Dongfeng General Hospital Affiliated to Hubei University,selected 110 patients with rheumatoid arthritis as the observation group, and selected 110 healthy people at the same period in this hospital for medical examination as the control group,both groups were given the synovial CCP expression positive rate and PADI4 gene expression detecting and correlation analysis.Results The synovial anti-CCP expression positive rates in the observation group and the control group were 70.9% and 9.1% re-spectively,and the observation group were significantly higher than the control group (P<0.05).The PADI4-104 genotype expression frequency compared between the observation group and control group,the difference were statistically significant (P<0.05).The G/G expression was more in the observation group,while the control group was more wit the C/G expres-sion.Pearson correlation analysis showed that in the observation group,synovial CCP positive expression were significant correlated to the expression of genotype PADI4-104 (r=0.344,P<0.05).Logistic regression analysis showed PADI4-104 genotype frequency were the main factors for the synovial CCP epitope expression (P<0.05).Conclusion The rheumatoid arthritis was more with synovial anti-CCP positive expression.There were also PADI4 polymorphism disorder expression, and clear correlation between the two.Thus impact the incidence of rheumatoid arthritis.
