[Efficacy of Hebi Formula Combined Methotrexate on Early Rheumatoid Arthritis Patients with Dis- harmony of Gan and Pi Syndrome and Its Effects on Serum MMP-3 and RANK/RANKL/OPG Expressions].

Objective To observe the efficacy of Hebi Formula (HF) combined Methotrexate (MTX) on early rheumatoid arthritis (RA) patients with disharmony of Gan and Pi syndrome (DGPS) and its effects on matrix metalloproteinase-3 (MMP-3) activator of nuclear factor-KB/receptor activator of nu- clear factor-KB/osteoprotegerin (RANK/RANKL/OPG). Methods Totally 72 early RA patients with DGPS were assigned to the treatment group and the control group according to random digit table, 36 in each group. Patients in the control group took MTX, while those in the treatment group additionally took HF. MTX dose was increased from 7. 5 mg to 12. 5 mg gradually, once per week, and the course of treatment was 24 weeks. Efficacy for Chinese medicine (CM) syndromes, ACR20 improvement rate, laboratory re- lated indices [ rheumatoid factor ( RF ) , erythrocyte sedimentation rate ( ESR ) , C-reactive protein (CRP) , anti-cyclic citrullinated peptide antibody (CCP)], serum levels of MMP-3, OPG, RANKL, and adverse reactions were observed. Results The standard arriving rate of ACR20 was 82. 86% (2935) in the treatment group, higher than that in the control group [51. 52% (173) ;P <0. 05). The effective rate of CM syndrome was 85. 7% (30f35) in the treatment group, higher than that in the control group [63. 6% (21/33) ;P <0. 05). Compared with before treatment in the same group, levels of RF,ESR,CRP,MMP-3, and RANKL decreased, the OPG level increased in the two groups after treatment (P <0. 05, P <0. 01). Compared with the control group, levels of RF, ESR, CRP, and RANKL all decreased with statistical difference (P <0. 01 , P <0. 05). Liver dysfunction occurred in 1 case of the treatment group. Leucopenia occurred in 1 case and liver dysfunction occurred in 2 cases of the control group. Conclusion HF com- bined MTX could improve symptoms of early RA patients with DGPS, and regulate bone destruction in- duced by RANK/RANKL/OPG systems.
