Background: Osteoarthritis (OA) is one of the most common chronic diseases today, and its prevalence and incidence are expected to increase as life expectancy increases. By investigating the inhibition of long non-coding RNA maternally expressed gene 3 (lncRNA MEG3) in OA, we hope to provide some new insights into the treatment of osteoarthritis.
Methods: By constructing an osteoarthritis model, the knee joint tissue of the model was observed using hematoxylin and eosin staining (HE) and computed tomography (CT).
Background: This study aimed to investigate the role of long non-coding (Lnc) RNA MEG3 on the osteogenesis of human bone marrow mesenchymal stem cells (hBMSCs).
Materials And Methods: The binding of miR-21-5p to LncRNA MEG3 and SOD3 was determined using luciferase reporter assay; fluorescence quantitative PCR was used to detect the expression of LncRNA MEG3 at different induction times. hBMSCs were transfected with LncRNA MEG3 overexpression vector and induced for osteoblasts for 14 days.
Background And Purpose: Suitable tissue-engineered scaffolds to replace human anterior cruciate ligament (ACL) are well developed clinically as the development of tissue engineering. As water-soluble polymer compound, polyvinyl alcohol (PVA) has been wildly used as the materials to replace ACL. The aim of this study was to explore the feasibility of constructing tissue-engineered ACL by the copolymerization of PVA and collagen (PVA/COL).

A total of 25 necrotic cartilage tissue samples and 25 normal tissue samples were collected from patients diagnosed with osteoarthritis at our hospital from December 2015 to December 2018. The mRNA expression levels of Bcl-xL, caspase-3, and matrix metalloproteinase-3 (MMP-3) in the normal and necrotic tissues were examined via quantitative polymerase chain reaction, and their protein expression levels were detected via western blotting.

Materials And Methods: HUCSCs were isolated and identified. Lentiviral encoding Bcl-xL was applied to modify HUCSCs.
Objectives: MicroRNA-21 (miR21) is aberrantly elevated in rheumatoid arthritis (RA) patients, the significance of this microRNA in RA pathogenesis and treatment, however, has not been investigated. In this study, by using RA-derived fibroblast-like synoviocyte (FLS) cells as a model, we investigated the effect and corresponding mechanism of miR21 inhibition on FLSs invasion.
Materials And Methods: miR21 expression in synovial tissue and FLSs in RA patients and non-RA controls were determined by stem-loop RT-PCR.
Objective: To investigate the clinical outcome of modified Blair ankle fusion for ankle arthritis.
Methods: Between November 2009 and June 2012, 28 patients with ankle arthritis were treated, among whom 11 had obvious foot varus deformity, and 17 were almost normal in appearance. There were 13 males and 15 females with an average age of 49.
