Ultrasound-Guided Sialendoscopy Surgery for Parotid Sialolithiasis Using Yttrium Aluminum Garnet (YAG)-Holmium Laser: A Prospective Case Series.

Background: Parotid sialolithiasis is a common condition in middle-aged individuals, with most cases occurring in the submandibular and sublingual glands, followed by the parotid glands and minor salivary glands. The treatment of salivary gland stones, particularly those of the parotid glands, remains challenging. Endoscopic surgery using a yttrium aluminum garnet (YAG)-holmium laser for parotid sialolithiasis is a minimally invasive approach that provides effective treatment for patients.

Ability to regulate immunity of mesenchymal stem cells in the treatment of traumatic brain injury.

Traumatic brain injury (TBI) is characterized by broad clinical symptoms in brain insult by external damages to the skull. TBI potentially leads to severe physical, cognitive, and emotional impairment. The complex biochemical reactions of inflammatory processes in TBI significantly influence brain function and clinical sequelae's overall severity.
