Objective To observe the therapeutic effect of Wangbi Capsules combined with Loxoprofen Sodium Tablets in treatment of rheumatoid arthritis. Methods A total of 101 patients with rheumatoid arthritis in Wuxi Hospital of Traditional Chinese Medicine from January 2021 to January 2023 were selected,and were divided into a control group (51 cases) and a treatment group (50 cases) using a random number table and sealed letter method. Patients of the control group orally took Loxoprofen Sodium Tablets,1 tablets/time,3 times daily. On this basis,patients in the treatment group orally took Wangbi Capsules,4 tablets/time,3 times daily. Patients of two groups were treated for 3 months. The clinical efficacy,joint tenderness,number of swelling,immune indicators,serum factors,and serum inflammatory factors were compared between two groups. Results After treatment,the total effective rate (96.00%) of the treatment group was higher than 82.35% of the control group (P<0.05). After treatment,the number of joint tenderness and swelling in both groups decreased (P<0.05),and the number of joint tenderness and swelling in the treatment group was less than that in the control group (P<0.05). After treatment,peripheral blood T helper cell 17 (Th17),Th17/Treg ratio,ESR,levels of serum CRP,RF,anti-CCP,IL-6,and TNF-α in both groups were decreased,while regulatory T cells (Treg) were increased (P<0.05). The peripheral blood Th17),Th17/Treg ratio,ESR,levels of serum CRP,RF,anti-CCP,IL-6,and TNF-α in the treatment group were lower than those in the control group,while Treg levels were higher than those in the control group (P<0.05). Conclusion The combination of Wangbi Capsules and Loxoprofen Sodium Tablets has shown good efficacy in treating rheumatoid arthritis,effectively reducing joint tenderness and swelling,and improving immune function and inflammatory response.
