N klA Case Report on a IV-degree Thermal Crush Injury of Right Upper Arm: The Application of Functional Prosthesis Implantation Technology.

Severe IV-degree thermal crush injury of limbs involved the subcutaneous fascia, muscle and bone, which may lead to amputation and has a great impact on the patient's quality of life. We can repair wounds with pedicle flaps or even free flaps, However, there are still huge challenges in bone defect of extremities and functional reconstruction. In recent years, with the development of functional prostheses, we have reconstructed limb functions in many patients helping them to complete their daily lives.

Management of combined massive burn and blast injury: A 20-year experience.

Introduction: Blast injuries are complex types of physical trauma resulting from direct or indirect exposure to an explosion, which can be divided into four classes: primary, secondary, tertiary, and quaternary. Primary blast injury results in damage, principally, in gas-containing organs such as the lungs (blast lung injury, BLI). BLI is defined as radiological and clinical evidence of acute lung injury occurring within 12h of exposure to an explosion and not due to secondary or tertiary injury.

Effects of depression on healing and inflammatory responses of acute wounds in rats.

This study aimed to elucidate the effect of depression on the healing of acute wounds in rats. We hypothesized that depression would have negative effects on inflammation and wound healing and that antidepressant therapy would reverse these effects. This study included 100 rats randomly allocated into five groups: control group (CG), depression group (DG), pre-depression group (PDG), antidepressant group (AG), and pre-antidepressant group (PAG).

Interleukin-35 Attenuates D-Galactosamine/Lipopolysaccharide-Induced Liver Injury via Enhancing Interleukin-10 Production in Kupffer Cells.

Interleukin (IL) -35 is an anti-inflammatory cytokine which exerts various beneficial effects on autoimmune diseases. However, whether IL-35 plays a role in endotoxin induced hepatitis demands clarification. This study aims to reveal the effect and mechanism of IL-35 on endotoxin induced liver injury.

A new method of wound treatment: targeted therapy of skin wounds with reactive oxygen species-responsive nanoparticles containing SDF-1α.

Objective: To accelerate wound healing through promoting vascularization by using reactive oxygen species (ROS)-responsive nanoparticles loaded with stromal cell-derived factor-1α(SDF-1α).

Methods: The ROS-reactive nanomaterial poly-(1,4-phenyleneacetone dimethylene thioketal) was synthesized, and its physical and chemical properties were characterized. ROS-responsive nanoparticles containing SDF-1α were prepared through a multiple emulsion solvent evaporation method.

Use of Amniotic Microparticles Coated With Fibroblasts Overexpressing SDF-1α to Create an Environment Conducive to Neovascularization for Repair of Full-Thickness Skin Defects.

As angiogenesis and vasculogenesis involve the complex network structures of various types of cells, extracellular matrix components, and cytokines, it is still difficult to exactly mimic the microenvironment of vascularization in vivo. In our study, we constructed a complex containing highly proliferative fibroblasts that can secrete extracellular matrix components and growth factors to chemotaxize endothelial progenitor cells (EPCs) in an attempt to create an ideal microenvironment for quick vascularization. Amniotic membrane microparticles (mAM) rich in type IV collagen (COL IV) and laminin (LN) were prepared, and human dermal fibroblasts (HDF) were infected with lentivirus (LV) of overexpression of SDF-1α to construct SDF-1α(ov)HDF.

Role of inhibition of p38 mitogen-activated protein kinase in liver dysfunction after hemorrhagic shock and resuscitation.

Background: The liver is one of the organs most frequently affected by trauma and hemorrhagic shock; the exact role of p38 mitogen-activated protein kinase (MAPK) activation in response to hepatic hemorrhagic shock/resuscitation (HS/R) remains unclear.

Materials And Methods: C57Bl/6 mice were divided into four groups: sham-operated group, SB-only group, control group, and SB + HS/R group. Hepatocellular injury (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) and tumor necrosis factor (TNF-α) and interleukin (IL-1β) messenger ribonucleic acid (mRNA) expression in the liver were assessed 6 h after resuscitation, p38 MAPK activation in the liver was assessed at 30 min after resuscitation.

Pathogenic alteration in severe burn wounds.

The present study aims to define the trend of time related changes with local bacterial alteration of bacterial resistance in severe burns in our burn center during a 12-year period. Retrospective analysis of microbiological results on severely burned wounds between 1998 and 2009 was carried out. A study of 3615 microbial isolates was performed.

A new strategy of promoting vascularization of skin substitutes by capturing endothelial progenitor cells automatically.

How to promote vascularization of a skin substitute is the key to successful skin transplantation. Current methods are mainly through releasing angiogenesis-related factors (ARF) or seeding angiogenesis-related cells (ARC), but the efficacy of these methods is not satisfactory, because angiogenesis needs participation of multiple factors, extracellular matrix and related cells. The latest research has demonstrated that endothelial progenitor cells (EPCs) originating from bone marrow and existing in peripheral blood are the key element participating in revascularization of adult tissues.

Successful treatment of a patient with an extraordinarily large deep burn.

Background: Treatment of extraordinarily large deep burns remains a huge clinical challenge.

Case Report: This article is a summary of our experience with the treatment of a patient with an extraordinarily large deep burn (99.5% TBSA and 23% fourth degree burn) by using the "microskin autografting and alloskin repeated grafting" method to close the deep burn wound because of scarcity of skin sources of the patient.

Reduction of CD47 on monocytes correlates with MODS in burn patients.

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.
