Correlation between abdominal computed tomography signs and postoperative prognosis for patients with colorectal cancer.

Background: Patients with different stages of colorectal cancer (CRC) exhibit different abdominal computed tomography (CT) signs. Therefore, the influence of CT signs on CRC prognosis must be determined.

Aim: To observe abdominal CT signs in patients with CRC and analyze the correlation between the CT signs and postoperative prognosis.

Low-intensity pulsed ultrasound promotes osteoarthritic cartilage regeneration by BMSC-derived exosomes via modulating the NF-κB signaling pathway.

Osteoarthritis is the most common disabling joint disease throughout the world, and the effect of therapy on its course is still unsatisfactory in clinical practice. Recent studies have shown that mesenchymal stem cell (MSC)-derived exosomes can promote cartilage repair and regeneration in osteoarthritis, indicating that these exosomes could be a novel and promising strategy for treating osteoarthritis. This study investigated whether low-intensity pulsed ultrasound (LIPUS) enhances the effects of bone marrow MSC (BMSC)-derived exosomes on cartilage regeneration in osteoarthritis and examined the underlying mechanism.
