Gouty arthritis

Suppressive effect of Sanmiao formula on experimental gouty arthritis by inhibiting cartilage matrix degradation: An in vivo and in vitro study.


Sanmiao formula (SM) is a compound prescription, which has been used in traditional Chinese medicine since the Ming Dynasty for gouty and rheumatoid arthritis treatments. However, no evidence has been unfolded to show the relationship between SM and gouty arthritis (GA), particularly inhibiting cartilage matrix degradation. In the present study, we undertook a characterization of anti-GA activity of SM using an in vivo rat model induced by potassium oxonate and cold bath together with in vitro studies with chondrocytes for further molecular characterization. Potassium oxonate and cold bath rats were treated with SM at doses of 7.2g/kg per day for 5days. SM treatments significantly suppressed the swelling rate and the severe pathologic changes in the joints of the animals in gout model. Inflammatory factors count by ELISA analysis, SM exhibited inhibition on IL-1β and TNF-α. Moreover, histological analysis of the joints and SM-serum substantially interfered with the MSU-induced expression of glycosaminoglycans (GAG), up-regulated the content of proteoglycan. Importantly, SM interfered with GA-augmented expression of matrix metalloproteinases (MMPs) -3 and aggrecanases (ADAMTS)-4, which are considered to be key enzymes in cartilage matrix degradation, and simultaneously augmented GA-reduced tissue inhibitors of metalloproteinases (TIMPs) -1 and -3 expression in the joints and chondrocytes. Therefore, SM is looking forward to be a potential novel agent that could prevent cartilage matrix degradation effectively in gouty arthritis, and this provides a new target for development of new medicines.

Traditional Chinese Medicine Treatment of Gouty Arthritis Based on Syndrome Differentiation



To observe the clinical effect and safety of traditional Chinese medicine (TCM) treatment in gouty arthritis (GA) based on syndrome differentiation.


81 patients of GA were enrolled from August 2013 to August 2014. They were divided into syndrome differentiation treatment group (27 cases), disease differentiation treatment group (27 cases) and basic treatment group (27 cases). The patients in syndrome differentiation treatment group were given corresponding TCM drug granules prescription by dialectical syndromes classification. The patients in disease differentiation treatment group were given TCM drug granules prescription. The patients in basic treatment group.were only given Diclofenac Sodium sustained-release tablets in acute phase, and Benzbromarone tablets in chronic phase. After 12 weeks treatments, all the patients received the measurements of serum uric acid (SUA), serum creatinine (SCr), blood urea nitrogen (BUN), triacylglycerol (TG), cholesterol (TC). The clinical efficacy, recurrence rate and adverse reactions were recorded and analyzed.


Syndrome differentiation treatment group achieved higher clinical efficacy than basic treatment group and disease differentiation treatment group (P<0. 05). Moreover, syndrome differentiation treatment were superior to disease differentiation treatment in improving of recurrence rate (P<0. 05). There were no obvious adverse reactions occurred. There were no clinical significant changes in blood, urine routine analysis, and electrocardiogram examination before and 3 months after the treatments.


The treatment of TCM in patients with GA based on syndrome differentiation showed definite therapeutic effects.

Therapeutic Effects of Chinese Medicine Herb Pair, Huzhang and Guizhi, on Monosodium Urate Crystal-Induced Gouty Arthritis in Rats Revealed by Anti-Inflammatory Assessments and NMR-Based Metabonomics.


The present study was undertaken to evaluate the therapeutic effects of Huzhang-Guizhi herb pair (HG), firstly included in Hu-Zhang Power documented in Taiping Shenghui Fang, on monosodium urate (MSU) crystals-induced gouty arthritis in rats. We found that pretreatment with HG in rats with gouty arthritis could significantly attenuate the ankle joint swelling, and this beneficial antigout effect might be mediated, at least in part, by inhibiting tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) production in synovial fluid as well as nuclear transcription factor-κB p65 (NF-κB p65) protein expression in synovial tissue. Moreover, metabonomic analysis demonstrated that 5 and 6 potential biomarkers associated with gouty arthritis in plasma and urine, respectively, which were mainly involved in energy metabolism, amino acid metabolism, and gut microbe metabolism, were identified. HG could reverse the pathological process of MSU-induced gouty arthritis through regulating the disturbed metabolic pathways. These results provided important mechanistic insights into the protective effects of HG against MSU-induced gouty arthritis in rats.
