Circulating exosomal lncRNA contributes to the pathogenesis of spinal cord injury in rats.

Exosome-derived long non-coding RNAs (lncRNAs) are extensively engaged in recovery and repair of the injured spinal cord, through different mechanisms. However, to date no study has systematically evaluated the differentially expressed lncRNAs involved in the development of spinal cord injury. Thus, the aim of this study was to identify key circulating exosome-derived lncRNAs in a rat model of spinal cord injury and investigate their potential actions.

The effect of poly(lactic-co-glycolic acid) conduit loading insulin-like growth factor 1 modified by a collagen-binding domain on peripheral nerve injury in rats.

Peripheral nerve injury (PNI) exists widely and seriously affects patients' daily lives. However, the effect of nerve repair is still limited, and only 50% of patients can recover useful functions. To overcome these obstacles, collagen-coated poly(lactic-co-glycolic acid) (PLGA) conduits loaded with CBD-IGF-1 were designed and tested in vitro and in vivo.

Sanders II type calcaneal fractures: a retrospective trial of percutaneous versus operative treatment.

Objective: The purpose of this study was to compare the clinical results of percutaneous reduction and Steinman pin fixation for Sanders II calcaneal fractures with those of operative management through an extensile lateral approach.

Methods: Fifty-three patients treated with standard open reduction and internal fixation (ORIF group) and 54 patients who had undergone percutaneous reduction and Steinman pin fixation (CRIF group) were retrospectively reviewed. There were no differences between the groups regarding sex, age or fracture classification.
