Meningiomas are among the most common primary intracranial tumors. Up to 20% of cases will show increased malignancy at histological examination (World Health Organization grade II or III). Effective pharmacotherapy, except for radiotherapy, is lacking. Therefore, it is necessary to study the pathogenesis of malignant meningioma to provide more treatment strategies. ⋯ Our results have suggested a tumor suppressive role for miR-195 in the tumorigenesis and progression of malignant meningioma by targeting FASN. In addition, NUP210, SPIRE2, SLC7A1, and DMTN might act as ceRNAs to regulate FASN expression by sponging miR-195.

To determine the rate and anatomical location of dural tears associated with spinal surgery using a percutaneous biportal endoscopic surgery (PBES) technique. We investigated the relationship between dural tears and the type of procedure and type of instrument used. ⋯ Most cases of incidental dural tear during PBES were treated with an endoscopic procedure. The incidence of dural tear was no greater than that associated with microscopic surgery. Our management strategy for incidental dural tears during PBES has been shown to be safe and effective.

To assess the role of the difference between the proximal junctional angle (PJA) and rod contouring angle (RCA) (PJA-RCA) in the development of postoperative proximal junctional angle (PJK) in Lenke I and II adolescent idiopathic scoliosis (AIS) patients. ⋯ Large postoperative PJA-RCA and decreased TK are risk factors for PJK in Lenke I and II AIS patients, especially those with PJA-RCA greater than 5°, and the occurrence of PJK should be highly considered.

To investigate the risk factors and predictive model of diarrhea among patients with severe stroke. ⋯ The National Institutes of Health Stroke Scale score at admission, the Glasgow Coma Scale score at admission, antibiotic use, gavage feeding time, and hospital stay before the occurrence of diarrhea independently predict diarrhea among patients with severe stroke. This model can be used to predict the risk of diarrhea among patients with severe stroke.

Spinal dural arteriovenous fistulas (DAVFs) are usually associated with neurologic dysfunction adjacent to the shunt point; however, the symptoms are uncommon far from the site of the fistula. To our knowledge, this is the first report of a patient with rapidly progressive isolated pseudobulbar palsy because of thoracic DAVF. ⋯ Although rare, thoracic DAVFs may present symptoms resembling brainstem infarction. Prompt surgical intervention is necessary for patients with thoracic DAVF presenting with rapidly progressive pseudobulbar palsy.
