January 2025

Department of Oral and Maxillofacial Surgery, The Affiliated Stomatological Hospital of Nanjing Medical University; State Key Laboratory Cultivation Base of Research, Prevention and Treatment for Oral Diseases; Jiangsu Province Engineering Research Centre of Stomatological Translational Medicine, Nanjing Medical University, Nanjing, 210029, China.

Delayed tooth extraction socket (TES) healing can cause failure of subsequent oral implantation and increase socioeconomic burden on patients. Excessive amounts of M1 macrophages, apoptotic neutrophils (ANs), and neutrophil extracellular traps (NETs) impair alveolar bone regeneration during TES healing. In the present study, we first discovered that conditioned medium (CM) collected from berberine-treated human bone marrow mesenchymal stem cells (BBR-HB-CM) accelerated TES healing.

Gout is a systemic metabolic disorder caused by elevated uric acid (UA) levels, affecting over 1% of the population. The most common complication of gout is gouty arthritis (GA), characterized by swelling, pain or tenderness in peripheral joints or bursae, which can lead to the formation of tophi. At present, western medicines like colchicine, febuxostat and allopurinol are the primary treatment strategy to alleviate pain and prevent flare-ups in patients with GA, but they have significant side effects and increased mortality risks.

Shear Wave Elastography (SWE) is an imaging technique that detects shear waves generated by tissue excited by Acoustic Radiation Force (ARF), and characterizes the mechanical properties of soft tissue by analyzing the propagation velocity of shear wave. ARF induces a change in energy density through the nonlinear propagation of ultrasound waves, which drives the tissue to generate shear waves. However, the amplitude of shear waves generated by ARF is weak, and the shear waves are strongly attenuated in vivo.
