Background: Tissue expansion for treating giant congenital melanocytic nevi (GCMN) is a commonly used surgical method. However, the procedure's efficacy is often hindered by anatomical and histologic characteristics and blood supply, particularly in the extremities and trunk. Enhancing expansion efficiency while reducing complications is thus a topic to be investigated, especially for pediatric patients undergoing rapid physical and psychological development with higher risks of noncompliance to medical instructions.

Background: Hypertrophic scars (HSs) cause functional impairment and cosmetic deformities following operations or burns (30% to 94%). There is no target therapy yet because the pathogenesis of HS progression is not well known. In tissue fibrosis, abnormal up-regulation of zinc finger E-box binding homeobox 1 (ZEB1) is an important cause for extracellular matrix (ECM) overexpression, which is the main molecular change in HSs.

Sepsis often causes organ dysfunction and is manifested in increased endothelial cell permeability in blood vessels. Early-stage inflammation is accompanied by metabolic changes, but it is unclear how the metabolic alterations in the endothelial cells following lipopolysaccharide (LPS) stimulation affect endothelial cell function. In this study, the effects of 1 μg/ml of LPS on the metabolism of human umbilical vein endothelial cells (HUVECs) were investigated, and the metabolic changes after LPS stimulation were explained from the perspective of mRNA expression, chromatin openness and metabolic flux.

One of the key targets of the inflammatory response in acute lung injury (ALI) is the human pulmonary micro-vascular endothelial cells (HPMVECs). Owing to its role in the activation of endothelial cells (ECs), CD40L figures prominently in the pathogenesis of ALI. Increasing evidences have showed that CD40L mediates inflammatory effects on ECs, at least in part, by triggering NF-κB-dependent gene expression.

Broadening the visible light absorption range and accelerating the separation and migration process of charge carriers are effective ways to improve photocatalytic quantum efficiencies. In this study, we show that poly heptazine imides with enhanced optical absorption and promoted charge carrier separation and migration could be obtained by means of a rational design of the band structures and crystallinity of polymeric carbon nitride. Copolymerization of urea with monomers such as 2-aminothiophene-3-carbonitrile would first generate amorphous melon with enhanced optical absorption, while further ionothermal treatment of melon in eutectic salts would increase the polymerization degree and create condensed poly heptazine imides as final products.

Common commercial porcine acellular dermal matrix (PADM) products take the form of a thin membrane. Given its dense structure, delaying vascularization after implantation remains an issue to be solved. In addition, overlaying multiple sheets to address deep wounds and large tissue defects that are difficult to repair by self-tissues could hinder tissue ingrowth, angiogenesis, and integration.

Diabetic wounds significantly affect the life quality of patients and may cause amputation and mortality if poorly managed. Recently, a wide range of cell-based methods has emerged as novel therapeutic methods in treating diabetic wounds. Adipose-derived stem cells (ASCs) are considered to have the potential for widespread clinical application of diabetic wounds treatment in the future.

Objective: We aimed to construct a novel prognostic model based on N6-methyladenosine (m6A)-related autophagy genes for predicting the prognosis of lung squamous cell carcinoma (LUSC).

Methods: Gene expression profiles and clinical information of Patients with LUSC were downloaded from The Cancer Genome Atlas (TCGA) database. In addition, m6A- and autophagy-related gene profiles were obtained from TCGA and Human Autophagy Database, respectively.

Quick and effective sterilization of drug-resistant bacteria inevitably became an ever-growing global challenge. In this study, a multifunctional composite (PDA/Cu-CS) hydrogel mainly composed of polydopamine (PDA) and copper-doped calcium silicate ceramic (Cu-CS) was prepared. It was confirmed that PDA/copper (PDA/Cu) complexing in the composite hydrogel played a key role in enhancing the photothermal performance and antibacterial activity.

Although many researches have explored the prognostic factors associated with length of hospital stay (LOS) of adult burn patients, fewer reports concerning pediatric burn patients have been conducted. The present study employed pediatric burn data to identify factors related to LOS and developed a novel model to assess the possibility of requiring surgery. A total of 750 children admitted for burns met the criteria for enrollment.

Under septic conditions, Lipopolysaccharide (LPS)-induced apoptosis of lung vascular endothelial cells (ECs) triggers and aggravates acute lung injury (ALI), which so far has no effective therapeutic options. Genistein-3'-sodium sulphonate (GSS) is a derivative of native soy isoflavone, which has neuro-protective effects through its anti-apoptotic property. However, whether GSS protects against sepsis-induced lung vascular endothelial cell apoptosis and ALI has not been determined.

Acute lung injury (ALI) is characterized by protein-rich pulmonary edema, critical hypoxemia, and influx of pro-inflammatory cytokines and cells. There are currently no effective pharmacon therapies in clinical practice. Syndecan-1 in endothelial cells has potential to protect barrier function of endothelium and suppress inflammation response.

Purpose: Point mutations of TP53 tumour suppressor are very rare in schwannomas. We aim to characterize the frequency of exonic copy-number changes of the gene in the tumour and to examine the association between TP53 alterations, phosphorylation status of p53 protein and clinical phenotypes.

Methods: The alterations of TP53 were screened by a combination of Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA) in a total of 44 vestibular schwannomas.

Due to the complexity of the skin tissue structure, the regeneration of the entire skin, including skin appendages such as hair follicles, is a big challenge. In addition, skin trauma is often accompanied by bacterial infections that delay the wound healing. Therefore, developing wound dressings, which promote hair follicle regeneration and inhibit bacterial infection in the wound healing process, is of great clinical significance.

Inflammation is characterized by early influx of polymorphonuclear neutrophils (PMNs), followed by a second wave of monocyte recruitment. PMNs mediate monocyte recruitment via their release of heparin binding protein (HBP), which activates CCR2 (CC-chemokine receptor 2) on monocytes. However, the pathways for such signal transmission remain unknown.

Thrombocytopenia is a common event in severely burned patients and associated with adverse outcome. The underlying relationship between the dynamic changes of platelet counts and mortality has not been well defined. We performed a 6-year retrospective chart of adult patients with a burn index of 50 or greater admitted to two burn centers and collected data on patient demographics, laboratory results, and patient outcomes.

The bacterial endotoxin or lipopolysaccharide (LPS) leads to the extensive vascular endothelial cells (EC) injury under septic conditions. Guanine nucleotide exchange factor-H1 (GEF-H1)/ROCK signaling not only involved in LPS-induced overexpression of pro-inflammatory mediator in ECs but also implicated in LPS-induced endothelial hyper-permeability. However, the mechanisms behind LPS-induced GEF-H1/ROCK signaling activation in the progress of EC injury remain incompletely understood.

Gram-negative bacterial lipopolysaccharide (LPS) induces a pathologic increase in lung vascular leakage under septic conditions. LPS-induced human pulmonary micro-vascular endothelial cell (HPMEC) apoptosis launches and aggravates micro-vascular hyper-permeability and acute lung injury (ALI). Previous studies show that the activation of intrinsic apoptotic pathway is vital for LPS-induced EC apoptosis.
