Mesenchymal Stem Cells Injection Is More Effective Than Hyaluronic Acid Injection in the Treatment of Knee Osteoarthritis With Similar Safety: A Systematic Review and Meta-Analysis.

Purpose: To evaluate the efficacy and safety of intra-articular injection of mesenchymal stem cells (MSCs) versus hyaluronic acid (HA) in the treatment of knee osteoarthritis (KOA).

Methods: Eligible randomized controlled trials (RCTs) were identified through a search of PubMed, Embase, the Cochrane Library, Web of Science, SinoMed, and CNKI databases from inception to March 2024. For meta-analysis, data on clinical outcomes were measured using visual analog scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and data on cartilage repair were measured using the Whole-Organ Magnetic Resonance Imaging Score (WORMS); data on safety were evaluated by the incidence of adverse events.

A single atom cobalt anchored MXene bifunctional platform for rapid, label-free and high-throughput biomarker analysis and tissue imaging.

Few of single-atom materials have been served as platform to analyze small molecules for surface assisted laser desorption/ionization mass spectrometry (SALDI-MS). Herein, a novel single Co atom-anchored MXene (Co-N-TiC) is prepared to achieve enhanced SALDI-MS and mass spectrometry imaging (MSI) performance for the first time. The Co-N-TiC films were prepared by a simple in situ self-assembly strategy to generate an efficient SALDI-MS platform.

Can radiologic parameters used to detect cervical spinal instability be used in patients with ankylosing spondylitis?

Introduction: Cervical spinal instability can be difficult to detect in the shock room setting even with the utilization of computed tomography (CT) scans. This may be especially true in patients with cervical degenerative disease, such as ankylosing spondylitis (AS). The purpose of this study was to investigate the influence AS has on various radiologic parameters used to detect traumatic and degenerative instability of the cervical spine, to assess if CT imaging in the shock room is diagnostically appropriate in this patient population.

Analysis of Factors Affecting Early Functional Recovery of Bernese Periacetabular Osteotomy.

Objectives: To explore factors affecting the efficacy of Bernese periacetabular osteotomy for the treatment of hip dysplasia.

Methods: A retrospective study was conducted on 44 patients with hip dysplasia who underwent Bernese periacetabular osteotomy with a modified Smith-Peterson approach between January 2017 and November 2019. Among them, 40 were women and four were men.

Additive Effects of VDBP and 1,25(OH)2D3 on the Viability and Apoptosis of Rheumatoid Arthritis Synovial Fibroblasts.

Aim: This study is to investigate the additive effect of Vitamin D-binding protein (VDBP) and 1,25(OH)2D3 on the viability and apoptosis of synovial cells from patients with rheumatoid arthritis (RA).

Methods: Synovial tissues and synovial fluid of patients with RA and osteoarthritis (OA) were collected. The expression of VDBP was analyzed with immunohistochemistry and ELISA.

IgMCD27 B cells possessed regulatory function and represented the main source of B cell-derived IL-10 in the synovial fluid of osteoarthritis patients.

Synovial inflammation is observed in patients with osteoathritis (OA) and likely contributed to its exacerbation. Regulatory B (Breg) cells are shown to suppress inflammation in various diseases, including rheumatoid arthritis (RA). To examine whether Breg cells also participated in OA, we examined the synovial fluid from OA patients, and compared with that in RA patients.

1,25-Dihydroxyvitamin D3 attenuates disease severity and induces synoviocyte apoptosis in a concentration-dependent manner in rats with adjuvant-induced arthritis by inactivating the NF-κB signaling pathway.

An aggressive proliferation of synoviocytes is the hallmark of rheumatoid arthritis (RA). Emerging evidence shows that inhibiting the NF-κB signaling pathway with 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] may be a therapeutic approach for controlling inflammatory diseases. In this study, we demonstrated the protective effects of three different 1,25(OH)2D3 concentration on adjuvant-induced arthritis (AA) rats through the NF-κB signaling pathway and their pro-apoptotic roles in cultured adjuvant-induced arthritis synoviocytes (AIASs).

Using IL-6 concentrations in the first 24 h following trauma to predict immunological complications and mortality in trauma patients: a meta-analysis.

Purpose: In previous studies, interleukin-6 (IL-6) has been shown to have a high predictive value for the development of complications and mortality after trauma; however, there is some uncertainty around these results. The aim of this meta-analysis was to assess the value of early IL-6 levels (within the first 24 h after trauma) for predicting post-traumatic complications [acute respiratory distress syndrome (ARDS), systemic inflammatory response syndrome (SIRS), sepsis, multiple organ failure (MOF), and multiple organ dysfunction syndrome (MODS)] and mortality.

Methods: A systemic literature review (from January 01, 1990, to June 03, 2017) of English-language articles was carried out using Pubmed, the Cochrane Central Register of Controlled Trials, Embase, and Web of Science.

Analysis of skeletal muscle microcirculation in a porcine polytrauma model with haemorrhagic shock.

Polytraumatised patients with haemorrhagic shock are prone to develop systemic complications, such as SIRS (systemic inflammatory response syndrome), ARDS (acute respiratory distress syndrome) and MOF (multiple organ failure). The pathomechanism of severe complications following trauma is multifactorial, and it is believed that microcirculatory dysfunction plays an important role. The aim of this study was to determine the changes in the microcirculation in musculature over time during shock and subsequent resuscitation in a porcine model of haemorrhagic shock and polytrauma.

Dose-dependent effects of peroxisome proliferator-activated receptors β/δ agonist on systemic inflammation after haemorrhagic shock.

Introduction: PPARβ/δ agonists are known to modulate the systemic inflammatory response after sepsis. In this study, inflammation modulation effects of PPARβ/δ are investigated using the selective PPARβ/δ agonist (GW0742) in a model of haemorrhagic shock (HS)-induced sterile systemic inflammation.

Methods: Blood pressure-controlled (35±5mmHg) HS was performed in C57/BL6 mice for 90min.

Outcomes of surgery for acromioclavicular joint dislocation using different angled hook plates: a prospective study.

Purpose: Hook plate fixation is widely used to treat acromioclavicular joint dislocation. However, there are many post-operative complications affecting the effect of treatment. The aim of this study is to evaluate the efficacy of the clavicular hook plate with different hook angles as a method of treatment in AC joint dislocation, and to guide the clinical application of hook plate.

The low binding affinity of ADAMTS4 for citrullinated fibronectin may contribute to the destruction of joint cartilage in rheumatoid arthritis.

Objectives: Rapid cartilage degradation in the joints is observed in rheumatoid arthritis (RA). ADAMTS4 (a disintegrin and metalloproteinase with thrombospondin motifs-4) degrades aggrecan, the primary component of cartilage, therefore contributing to joint erosion in RA. The proteolytic activity of ADAMTS4 is inhibited by fibronectin (FN).
