RESUMEN
Ginkgolide B has been known to inhibit cell apoptosis by modulating multiple cytokines and plays an important role in neuroprotection. Signal transducer and activator of transcription 1 (STAT1) has been studied in a spinal cord injury (SCI) model. However, the role of Ginkgolide B in SCI treatment remains unclear. This study investigated the potential mechanism of Ginkgolide B using an SCI rat model. SD rats were used to generate an SCI model followed by Ginkgolide B injection (4 mg/kg) for 14 days. Spinal cord tissue samples were examined using hematoxylin and eosin (H&E) staining. The expression of STAT1 was determined by western blot. Using a dyskinesia scale, intervention with Ginkgolide B significantly decreased the severity of SCI. H&E staining revealed less nuclear condensation and cell necrosis in SCI rats after treatment with Ginkgolide B. STAT1 expression was significantly increased in SCI model rats, but was lower after Ginkgolide B treatment. Therefore, Ginkgolide B can effectively inhibit STAT1 expression and alleviate SCI.

Amputations associated with fireworks are customarily treated by stump revision resulting in permanent disability. In this case report, we present an eight-year old boy who suffered an amputation of his right distal index finger at the level of the epiphyseal disk with degloving injury of the amputated finger caused by fireworks. Successful re-implantation was achieved. Two-year follow-up revealed fair cosmesis and acceptable functional and aesthetic recovery though the free distal phalanx had been absorbed completely. Re-implantation of a degloving amputation finger caused by fireworks is possible and can provide good distal soft tissue coverage and recovery of sensory and motor functions.
