Emerging antibacterial nanozymes for wound healing.

Wound infections continuously impose a huge economic and social burden on public healthcare. Despite the effective treatment of bacteria-infected wounds after using traditional antibiotics, the misuse of antibiotics usually causes the spread of bacterial resistance and decreases therapeutic outcomes. Therefore, the development of efficient antibacterial agents is urgently needed.

The clinical comparative study on high and low viscosity bone cement application in vertebroplasty.

Objective: To investigate the clinical effect of high and low viscosity bone cement in vertebroplasty for treatment of osteoporotic vertebral compression fractures.

Methods: 40 cases of patients with osteoporotic thoracolumbar compression fractures admitted into department of orthopeadics in our hospital were reviewed. All patients were divided into high viscosity bone cement group (20 cases) and low viscosity bone cement group (20 cases).
