RESUMO
Alternation of surface markers on monocytes is associated with the development of inflammation. The goals of the present study were to detect CD47 expression on monocytes by flow cytometry and explore its relationship with disease severity and MODS in burned patients. The results show CD47 expression on monocytes from all burned patients (n = 21) was lower than that from the healthy population (n = 21) for 24 days after burn. There was a significant difference in CD47 expression on monocytes between the patients with differing burn severity in the first 7 days after injury (P < 0.05). Considering the relationship between CD47 expression and MODS, we found the CD47 expression on monocytes from patients with MODS was lower (P < 0.05) in the first 3 days after injury than that from patients without MODS. In conclusion, diminished CD47 expression on monocytes is associated with burn severity and the occurrence of MODS in burn patients.

Burn-induced tracheal stenosis is rare. This article reports an extensive burn patient who developed severe tracheomalacia and stenosis before wound healing. Given the ineffectiveness of the conventional techniques available for the treatment of tracheal stenosis, we used an extended tracheal cannula to dilate the narrowed part of the trachea successfully. As a result, the extensive burn wound was repaired, and the symptoms of tracheal stenosis were eventually relieved. No serious restenosis was observed during a 2-year follow-up period.
