Construction of a miRNA Signature Using Support Vector Machine to Identify Microsatellite Instability Status and Prognosis in Gastric Cancer.

Background: The specific role and prognostic value of DNA repair and replication-associated miRNAs in gastric cancer (GC) have not been clearly elucidated. Therefore, comprehensive analysis of miRNAs in GC is crucial for proposing therapeutic strategies and survival prediction.

Methods: Firstly, clinical information and transcriptome data of TCGA-GC were downloaded from the database.

Perfect pair, scopes unite - laparoscopic-assisted transumbilical gastroscopy for gallbladder-preserving polypectomy: A case report.

Background: Gallbladder polyps are one indication for cholecystectomy, but this procedure carries some disadvantages, including the potential for severe injury and high risk of post-operative complications. Laparoscopy combined with endoscopic surgery is a minimally invasive treatment option. We herein report a young patient with a gallbladder polyp who was successfully discharged from the hospital after laparoscopic-assisted endoscopy.
