Application of the laparoscopic auxiliary needle device in the treatment of pediatric inguinal hernia: an eight-year experience.

Background: Pediatric inguinal hernia is a common surgical condition among children. In this study, we present the application of a self-designed laparoscopic auxiliary needle device (China Patent Number: ZL 201320479515.5) and evaluate its effectiveness in laparoscopic percutaneous extraperitoneal closure in pediatric patients.

Molecular Dynamics Simulation on the Wettability of Nanoscale Wrinkles: High Water Adhesion of Rose Petals.

Understanding the high water adhesion of rose petals is of great significance in artificial surface design. With all-atom molecular dynamics simulation, the wettability of nanoscale wrinkles was explored and compared to that of nanoscale strips with favorable hydrophobicity. The dewetting and wetting of gaps between nanoscale structures represent the Cassie-Baxter (CB) and Wenzel (WZ) states of the macroscopic droplet deposited on the textured surface, respectively.
