Rheumatoid, fasting venous blood
BLOOD
First, 5 mL of fasting venous blood was collected from patients in both groups before and after treatment. After centrifugation at 3000 r/min for 10 minutes, the supernatant was pretreated and stored at low temperature and used to detect the relevant indexes of patients. Blood ESR was measured by the Westergren methods. CRP was measured by immunodiffusion. Rheumatoid factor (RF) was measured by latex agglutination test. Anti-cyclic citrullinated peptide (anti-CCP) was measured by enzyme-linked immunosorbent assay. The reagents were purchased from Shanghai Chemical Biotechnology Co., and the operation procedure was performed strictly according to the manufacturer instructions.
