Abstract
BACKGROUND
Rheumatoid arthritis (RA) is a prevalent clinical autoimmune disease that is commonly treated with diclofenac and methotrexate. In recent years, the application of traditional Chinese medicine in RA has received widespread attention; it promotes blood circulation, strengthens the immune system, and eliminates evil. The sinomenine preparation of Zhingqeng Fengtongning is studied as a possible treatment for patients with RA.
AIM
To explore the value of sinomenine injection into the articular cavity for the treatment of RA.
METHODS
A total of 94 patients with RA treated from January 2019 to January 2021 were selected and divided into the study and control groups with 47 patients each using a simple random number table method. Both groups received conventional treatment with diclofenac sodium and methotrexate tablets. The control group received diproxone and lidocaine by intra-articular administration while the study group received an intra-articular administration of the sinomenine preparation of Zhengqing Fengning and lidocaine. χ2 test was used to evaluate the therapeutic effect and synovial thickness, degree of pain through the visual analog scale (VAS), blood flow grade, arthroinflammatory indexes [rheumatoid factor (RF), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR)] before and after treatment in the two groups.
RESULTS
The total effective rate of the study group (93.62%) was higher than that of the control group (78.72%) (P < 0.05). Before treatment, there were no significant differences between the two groups in terms of synovial thickness, VAS score, blood flow grading, levels of RF, and ESR (P > 0.05). After treatment, the synovial thickness and VAS score were significantly lower (P < 0.05) in the study group than in the control group (2.05 ± 0.59 mm vs 2.87 ± 0.64 mm and 2.11 ± 0.62 vs 2.90 ± 0.79 scores, respectively). The rate of blood flow at grade 0 in the study group (76.60%) was higher than that in the control group (57.45%), and the rate of blood flow at grade I (10.64%) was lower than that in the control group (31.91%) (P < 0.05). Furthermore, the levels of RF (55.61 ± 6.13 U/mL), CRP (11.43 ± 3.59 mg/L), and ESR (29.60 ± 5.56 mm/h) in the study group were lower than those in the control group (73.04 ± 9.23 U/mL, 15.07 ± 4.06 mg/L, 36.64 ± 6.10 mm/h, respectively) (P < 0.05).
CONCLUSION
Sinomenine administration of Zhengqing Fengtongning in the articular cavity with conventional treatment of RA can improve ultrasonographic blood flow and synovial thickness, reduce pain, regulate inflammation, and enhance therapeutic effect.
