OBJECTIVE Anti-mutated citrullinated vimentin (MCV) antibodies have been reported as a fairly sensitive serological marker of rheumatoid arthritis (RA). We evaluated the diagnostic value of anti-MCV in a large cohort of Chinese patients with early RA. METHODS One hundred seventy patients with early RA (<1 yr duration), 66 with other rheumatic diseases, 10(More)
OBJECTIVE To detect anti-peptidylarginine deiminase 4 (PAD4) antibody in patients with rheumatoid arthritis (RA) and to investigate its clinical significance in the pathogenesis of RA. METHODS Serum samples were obtained from 109 patients with RA, 67 systemic lupus erythematosus (SLE), 48 primary Sjögren's syndrome (pSS), 41 systemic sclerosis (SSc), 34(More)
Rheumatoid arthritis (RA) is a systemic autoimmune disease mediated by T cells. Collagen type II (CII) is one of the autoantigens associated with RA. CII263-272 is a predominant CII antigenic peptide that can induce T-cell activation upon binding to MHC and interaction with the appropriate T-cell receptor (TCR). Altered CII263-272 peptides with substitution(More)
To examine the incorporation of anti-CCP antibodies into the American College of Rheumatology (ACR) classification criteria for rheumatoid arthritis (RA) and to evaluate the advantages of the revised anti-CCP criteria in diagnosing Chinese patients. Patients who suffered from arthritic problems during the recent 2 years were selected from the Department of(More)
This study examined the psychometric properties of the Spence Children's Anxiety Scale (SCAS) in a Mainland Chinese community sample. The 38-item Chinese version of SCAS was administered to 1878 children and adolescents. Multiple group confirmatory factor analyses supported a common 6-factor model of SCAS for children and adolescents, and for boys and(More)
OBJECTIVES To develop classification criteria for early rheumatoid arthritis (ERA) based on a large cohort of early inflammatory arthritis patients and to evaluate the performance of these criteria. METHODS The study population comprised a cohort of early inflammatory arthritis patients with symptom duration less than one year. Classification criteria of(More)
Cytokines play a key role in the bone destruction of rheumatoid arthritis (RA). Interleukin-21 (IL-21) promotes osteoclastogenesis in RA in a receptor activator of nuclear factor-κB ligand (RANKL)-dependent way. Whether IL-21 is capable of promoting osteoclastogenesis directly in the absence of RANKL remains unknown. In the present study, we examined the(More)
OBJECTIVE Antibodies against citrulline-containing epitopes, such as antiperinuclear factor (APF), antikeratin antibodies (AKA), antifilaggrin antibodies, and anticyclic citrullinated peptide (anti-CCP) antibodies, are specific in rheumatoid arthritis (RA). Detection of APF, AKA, and anti-CCP has been widely used in clinical practice. However, studies on(More)
The receptor activator of nuclear factor-κB ligand (RANKL), as a member of the tumor necrosis factor (TNF) family, plays an essential role in osteoclast differentiation and function. Chemokines and their receptors have recently been shown to play critical roles in osteoclastogenesis, however, whether CXCL16-CXCR6 plays role in RANKL-mediated(More)
The present study investigated anxiety disorder symptoms in Chinese preschool children. A total of 1,854 mothers of children aged 3-6 years completed the 28-item Chinese version of Spence Preschool Anxiety Scale (PAS). Results demonstrated that the structure of anxiety in Chinese preschool children included five factors, and this five-factor structure(More)
