Efficacy of platelet-rich plasma injection in the treatment of frozen shoulder: A systematic review and meta-analysis.

Background: Frozen shoulder (FS) is characterized by progressive shoulder pain and a limited range of motion. Recently, platelet-rich plasma (PRP) injection is a newly developed treatment option for patients with FS and its efficacy needs to be examined.

Objective: By conducting a systematic review and meta-analysis, this study attempted to evaluate the efficacy of PRP injection in the treatment of patients with FS.

A Targeted Erythrocyte Membrane-Encapsulated Drug-Delivery System with Anti-osteosarcoma and Anti-osteolytic Effects.

Chemotherapy is one of the main treatment methods for osteosarcoma. However, conventional chemotherapy lacks targeting properties, and its long-term and extensive use will have serious side effects on patients. For this reason, a multifunctional nanodrug system (V-RZCD) targeting osteosarcoma was developed in this study.
