The achievements of burn metabolism and nutrition in China are briefly presented. Advance a new theory "Enterogenous Hypermetabolism". Develop a formula to calculate calorie needs in Chinese burn adults. Put forward new ideas on glucose absorption, neo glycogenesis, insulin resistance, and the use of hypoglycemic agent after burn injury. Observe the variation of plasma level of free aminoacids, investigate the changes and mechanisms of 26S proteasome and 19S regulator in skeletal muscle of burn trauma, and the clinical application and its mechanism of glutamine and arginine. Introduce the approach of (13)C NMR spectroscopy to investigate the alterations of hepatic anabolism functions in severely burned rats. Offer supplying the suitable dosage of vitamin A, C, E and microelement of zinc, copper, ferrum for burn patients. Carry out serial studies of early enteral and parenteral nutrition, and compare enteral nutrition with parenteral nutrition. Early enteral nutrition with synbiotics might be beneficial to the controlling of burn infection. Both glucagon like peptide-2 (GLP-2) and intestinal trefoil factor (ITF) exhibit protective effect on intestinal mucosa in minimizing injury and protecting barrier function. The choice of suitable opportunity to use rhGH (growth hormone) is investigated. In addition, advance the view points of ischemia and anoxia in metabolism, anti-inflammatory immune and nutrition.

Purpose: Previous studies have reported divergent sexual responses to aging; however, specific variations in gene expression between aging males and females and their potential association with age-related retinal diseases remain unclear. This study collected data from public databases and developed a comprehensive comparison of retina between aging females and males.
Methods: Single-cell RNA (scRNA) and bulk RNA sequencing data of the aging retina from females and males in public databases were utilized for integrated analysis to investigate sex-biased expression in retina.

Introduction: Patients with suspected bacterial infection frequently receive empiric, broad-spectrum antibiotics prior to pathogen identification due to the time required for bacteria to grow in culture. Direct-from-blood diagnostics identifying the presence or absence of bacteria and/or resistance genes from whole blood samples within hours of collection could enable earlier antibiotic optimisation for patients suspected to have bacterial infections. However, few randomised trials have evaluated the effect of using direct-from-blood bacterial testing on antibiotic administration and clinical outcomes.

Wound healing is a central physiological process that restores the barrier properties of the skin after injury, comprising close coordination between several cell types (including fibroblasts and macrophages) in the wound bed. The complex mechanisms involved are executed and regulated by an equally complex, reciprocal signalling network involving numerous signalling molecules such as catabolic and anabolic inflammatory mediators (e.g.

Chronic wounds and injuries remain a substantial healthcare challenge, with significant burdens on patient quality of life and healthcare resources. Mesenchymal stromal cells (MSCs) present an innovative approach to enhance tissue repair and regeneration in the context of wound healing. The intrinsic presence of MSCs in skin tissue, combined with their roles in wound repair, ease of isolation, broad secretory profile, and low immunogenicity, makes them especially promising for treating chronic wounds.
