[Whole esophagus deep burns with a metal foreign body in the stomach: a case report].

Whole esophagus deep burn is an extremely rare upper gastrointestinal tract disease. We report a case of severe burns of involving extensive body skin, eyes, throat, and esophagus. Endoscopic examination revealed acute necrotizing esophagitis and detected a metal foreign body in the stomach.

[Exogenous putrescine causes renal function impairment and cell apoptosis in rats].

Objective: To explore the effect of exogenous putrescine on renal function and cell apoptosis in rats.

Methods: Ninety SD rats were randomized into control group (n=10), high-dose putrescine group (P1 group, n=40), and low-dose putrescine group (P2 group, n=40) with intraperitoneal injections of 2 ml of normal saline, 50 µg/g putrescine, and 25 µg/g putrescine, respectively. At 24, 48, 72 and 96 h after the injections, 10 rats from each group were sacrificed to examine serum Cr and BUN levels, histological changes in the kidneys, and renal cell apoptosis (TUNEL assay).

[Clinical application of composite skin graft consisting of acellular allogenic dermis and autologous skin].

Objective: To study the procedures of applying composite skin graft consisting of acellular allogenic dermis and autologous skin in the treatment of full-thickness burns and scar formation.

Methods: Fifteen burn wounds in 8 patients were treated with the composite skin graft using one-stage grafting.

Results: Complete wound healing was achieved in 13 wounds.

[Effect of protein kinase on endothelial cytoskeleton induced by septic shock].

Objective: To study the effect of cGMP-dependent protein kinase (PKG) on the pathogenesis of septic shock.

Methods: Confluent endothelial cells were disintegrated and centrifugated to obtain cell lysates after being treated with LPS or PKG activator 8-Br-cGMP. PKG activity of lysates was measured with radioactive isotope label method in a reaction system of phosphorylation of specific substrate H2B by PKG, and the shape and the distribution of intracellular filamentous actin were detected by specific fluorescence staining.

[The applied anatomy of axial subdermal vascular network skin flap and its application in the management of deep burn wound].

Objective: To explore the anatomical basis and clinical application of axial subdermal vascular network skin flap (ASVNF) in the management of deep burn wounds.

Methods: Twelve samples of skin and subcutaneous tissue of lower extremities from adult cadavers were anatomically observed. The course, branching and the architecture of the subdermal vascular network (SVN) in the superficial facia and the ultra-thin area of the anterolateral femoral and saphenous axial subdermal vascular network skin flaps were intensively studied.
