[Exploration of relationship between postoperative serum caveolin-1 contents and delayed healing of tibial fracture patients].

Objective: To explore relationship between postoperative serum caveolin-1 contents after open reduction and internal fixation and delayed healing of tibial fracture patients.

Methods: From April 2018 to June 2020, 134 tibial fracture patients underwent open reduction and internal fixation were included, and divided into delayed healing group and normal healing group according to fracture healing condition. Contents of serum caveolin-1 protein before operation, 1, 4, 8, 12 weeks after operation between two groups were compared.

Multimaterial 3D Printing of Highly Stretchable Silicone Elastomers.

3D printing of silicone elastomers with the direct ink writing (DIW) process has demonstrated great potential in areas as diverse as flexible electronics, medical devices, and soft robotics. However, most of current silicones are not printable because of their low viscosity and long curing time. The lack of systematic research on materials, devices, and processes during printing makes it a huge challenge to apply the DIW process more deeply and widely.
