Identification of spin effects in the anomalous Righi-Leduc effect in ferromagnetic metals.

The emerging of spin caloritronics leads to a series of new spin-thermal related effects, such as spin Seebeck effect (SSE), spin Nernst effect (SNE) and their corresponding inverse effects. Anomalous Righi-Leduc effect (ARLE) describes that a transverse temperature gradient can be induced by a longitudinal heat flow in ferromagnets. The driving force and the response of the ARLE are all involved with heat.

[Influence of omega-3 polyunsaturated fatty acids on inflammation-related parameters in lung tissue of rats with severe scald].

Objective: To study the effect of omega-3 polyunsaturated fatty acids (omega-3 PUFA) on inflammation in lung tissue of rats with severe scald and its mechanism.

Methods: Seventy-two adult SD rats were divided into sham scald group (SS, n = 8), treatment group 1 (T1, n = 32), treatment group 2 (T2, n = 32) according to the random number table. Rats in T1 group and T2 group were inflicted with 30% TBSA full-thickness scald, and then they were respectively injected with 100 g/L omega-3 PUFA (1 mL/kg) and 200 g/L long-chain fatty acid (2 mL/kg) via tail vein within 5 minutes after burn.

[Analysis of drug resistance and risk factors of Enterobacteriaceae in burn units].

Objective: To study the risk factors of infection of extended-spectrum beta-lactamases (ESBL)-producing strains and drug resistance of Enterobacteriaceae that infected burn patients.

Methods: A retrospective study was performed on clinical information of 92 patients with Enterobacteriaceae infection in our burn unit from January 2001 to December 2008. The distribution and drug resistance of Enterobacteriaceae, and the detection rate, drug resistance of ESBL-producing strains, and its risk factors of nosocomial infection were analyzed.

[The influence of changes in the levels of calcitonin gene-related peptide and neuropeptide Y on cardiac function of severe burn patients during shock stage].

Objective: To investigate the influence of the changes in the levels of calcitonin gene-related peptide (CGRP) and neuropeptide Y (NPY) on cardiac function of severe burn patients during shock stage.

Methods: Sixty severe burn patients with total burn surface area larger than 30% were enrolled as experiment group (E group) , and they received fluid resuscitation and debridement during shock stage. Sixty healthy volunteers were enrolled as control group (C group).

[Protective effects of enteral immuno-nutrition on intestinal mucosa injury in burned rats].

Objective: To investigate the protective effects of enteral immuno-nutrition on intestinal mucosa injury following severe burn.

Methods: Sixty-four Wistar rats with 30% total body surface area (TBSA) full-thickness burn were randomly divided into enteral nutrition (EN, n=32) group and enteral immuno-nutrition (EIN, n=32) group. Another 8 Wistar rats were used as normal control group.

Ligustrazine attenuates acute lung injury after burn trauma.

Acute lung injury is a common complication in patients with extensive burns in which the burned area exceeds 30% of the total body surface area (TBSA). This study was undertaken to evaluate the effect of Ligustrazine on burn-induced lung injury as well as the release of interleukin-8 (IL-8) in rats to characterize the role of Ligustrazine and IL-8 in lung injury after burn trauma. Sprague-dawley rats were divided into three groups: (1) sham group, rats who underwent sham burn; (2) control group, rats given third-degree burns over 30% TBSA and lactated Ringer solution for resuscitation; and (3) Ligustrazine group, rats given burn injury and lactated Ringer's solution with Ligustrazine inside for resuscitation.
