[Arthroscopic Eden-Hybinette procedure with Triple-Pulley and four point anti-rotation fixation technique for recurrent anterior dislocation of shoulder joint].

Objective: To explore effectiveness of arthroscopic Eden-Hybinette procedure with Triple-Pulley and four point anti-rotation fixation technique in the treatment of recurrent anterior dislocation of shoulder joint.

Methods: A clinical data of 14 patients with recurrent anterior dislocation of shoulder joint and glenoid bone defect, who were met the selective criteria and admitted between February 2021 and February 2022, was retrospectively analyzed. All patients were treated with arthroscopic Eden-Hybinette procedure and the bone blocks were fixed by using Triple-Pulley and four point anti-rotation fixation technique.

Long-term hypoxic atmosphere enhances the stemness, immunoregulatory functions, and therapeutic application of human umbilical cord mesenchymal stem cells.

Aims: Mesenchymal stem cells (MSCs) are usually cultured in a normoxic atmosphere (21%) in vitro, while the oxygen concentrations in human tissues and organs are 1% to 10% when the cells are transplanted in vivo. However, the impact of hypoxia on MSCs has not been deeply studied, especially its translational application.

Methods: In the present study, we investigated the characterizations of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) in hypoxic (1%) and normoxic (21%) atmospheres with a long-term culture from primary to 30 generations, respectively.

Amentoflavone maintaining extracellular matrix homeostasis and inhibiting subchondral bone loss in osteoarthritis by inhibiting ERK, JNK and NF-κB signaling pathways.

Amentoflavone (AF), a plant biflavone isolated from Selaginella sinensis ethanol extract, is characterized by anti-inflammatory and anti-oxidant properties. According to previous studies, inflammation and oxidative stress are closely related to the pathophysiology of osteoarthritis (OA). However, the effects and mechanisms of AF on OA have not been elucidated.

Galangin Promotes Tendon Repair Mediated by Tendon-Derived Stem Cells through Activating the TGF-β1/Smad3 Signaling Pathway.

Tendon injury is a prevalent orthopedic disease that currently lacks effective treatment. Galangin (GLN) is a vital flavonoid found abundantly in galangal and is known for its natural activity. This study aimed to investigate the GLN-mediated molecular mechanism of tendon-derived stem cells (TDSCs) in tendon repair.

Bidirectional two-sample mendelian randomization analysis identifies causal associations between age at menarche and sarcopenia-related traits.

Background: Observational studies have shown that the age of menarche is associated with sarcopenia, but confounding factors make the causal relationship difficult to infer.

Objective: Therefore, we conducted a bidirectional two-sample Mendelian randomized (MR) analysis to evaluate the potential causal relationship between age at menarche and sarcopenia-related traits (hand grip strength, lean mass, walking pace).

Methods: We obtained the latest aggregate statistics from the Genome-wide association studies (GWAS) database on the age of menarche of 182,416 participants from ReproGen, the appendicular lean mass of 244,730 participants from EMBL's European Bioinformatics Institute, the left-hand grip strength of 401,026 participants, the right-hand grip strength of 461,089 participants and the usual walking pace of 459,915 participants from the UK Biobank.

Xanthorrhizol Ameliorates Oxidative Stress and Inflammation in Freund's Complete Adjuvant-Induced Rheumatoid Arthritis in Rats.

Rheumatoid arthritis (RA) is an inflammatory disease and a common cause of disability. This study is aimed to ascertain the therapeutic potentials of the xanthorrhizol against Freund's complete adjuvant (FCA)-stimulated RA in rats. The RA was initiated in the rats via injecting FCA (0.
