To identify susceptibility loci for ankylosing spondylitis, we performed a two-stage genome-wide association study in Han Chinese. In the discovery stage, we analyzed 1,356,350 autosomal SNPs in 1,837 individuals with ankylosing spondylitis and 4,231 controls; in the validation stage, we analyzed 30 suggestive SNPs in an additional 2,100 affected(More)
The objective of this study was to investigate the expression of IL-23 and IL-17 and the influence of IL-23 on IL-17 production in ankylosing spondylitis (AS) patients. IL-23 and IL-17 levels in the serum and supernatants of cultured peripheral blood mononuclear cells (PBMCs) were determined by ELISA. IL-23p19 mRNA expression in PBMCs were analyzed using(More)
OBJECTIVE To assess the usefulness of measuring serum matrix metalloproteinase 3 (MMP-3) and macrophage colony-stimulating factor (M-CSF) in patients with ankylosing spondylitis (AS). METHODS Serum levels of MMP-3 and M-CSF were measured in AS patients who did and did not receive infliximab treatment. These were compared with those of 28 healthy subjects.(More)
OBJECTIVE To investigate the role of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) in spondylarthropathy (SpA) synovitis. METHODS Paired samples of synovial biopsy tissue as well as serum and synovial fluid (SF) from 41 patients with SpA and 20 patients with rheumatoid arthritis (RA) and serum samples from 20(More)
Ankylosing spondylitis (AS) is a potentially disabling form of seronegative spondyloarthritis. The main symptom of AS is inflammatory spinal pain; with time, some patients develop ankylosis and spinal immobility. The pathology mainly affects the entheses, where ligaments, tendons and capsules are attached to the bone. Three processes are observed at the(More)
INTRODUCTION Dendritic cells (DCs) are capable of inducing immunity or tolerance. Previous studies have suggested plasmacytoid DCs (pDCs) are pathogenic in systemic lupus erythematosus (SLE). However, the functional characteristics of directly isolated peripheral circulating blood pDCs in SLE have not been evaluated previously. METHODS Peripheral blood(More)
MicroRNAs (miRNAs) play a key role in the regulation of almost all the physiological and pathological processes, including bone metabolism. Recent studies have suggested that miR-27 might play a key role in osteoblast differentiation and bone formation. Increasing evidence indicates that the canonical Wnt signaling pathway contributes to different stages of(More)
The objective of this study is to evaluate the efficacy and safety of rhTNFR:Fc: a recombinant tumor necrosis factor receptor:Fc fusion protein compared with methotrexate (MTX) in patients with rheumatoid arthritis in China. We treated 238 patients with active rheumatoid arthritis with either twice weekly subcutaneous injection rhTNFR:Fc (25 mg) or weekly(More)
OBJECTIVES The prevalence of spondyloarthritis (SpA) and its prototype ankylosing spondylitis (AS) varies considerably in different parts of the world. With 20% of the world's population in China, there is potential for a significant disease burden. Eight of the 10 articles providing primary data on the prevalence of SpA in China are in the Chinese(More)
To investigate the prevalence of hepatitis B virus (HBV) infection in systemic lupus erythematosus (SLE) patients in southern China, SLE inpatients were retrospectively investigated for their HBV infection rate. Fifteen SLE patients positive for hepatitis B surface antigen (HBsAg) were followed up. Furthermore, serum interferon (IFN)-α levels among SLE(More)
