ABSTRACT
The 14th Asia Pacific Burn Congress, the 18th Chinese Symposium on Burn Medicine, and the 2023 Huaxia Burn Forum was held successfully in Chongqing from September 13th to 16th, 2023. More than 1 000 participants from more than 10 countries and regions attended the congress, including over 100 overseas experts. The theme of the congress was homage, heritage, and innovation, and three-day academic exchange was held in the form of academician forum, keynote forum, and seven thematic sub-forums focused on the hot spots and difficulties in the fields of burns, trauma, wound repair, and related fields. The congress was compact, comprehensive, in-depth, and fruitful, with warm atmosphere at the meeting site.

Cognitive disorders after burns is an important problem that cannot be ignored in the diagnosis and treatment of burn patients. Its mechanism may be related to the activation of inflammatory response, destruction of the blood-brain barrier, hypothalamic-pituitary-adrenal axis imbalance, nerve cell changes, etc. Mechanism-specific prevention and treatment will be the best choice to reduce post-burn cognitive disorders in the future. This review introduces the research advances in epidemiology, risk factors, possible pathogenesis, diagnosis, treatment, and prevention of cognitive disorders in burn patients, in order to provide a reference for timely and accurate assessment, treatment, and prevention of cognitive disorders in burn patients.

Wound healing is a complex and critical process, which includes three stages: inflammation, proliferation, and remodeling. The epidermal cells are precisely regulated in this process. On one hand, keratinocytes around the wound edge migrate and proliferate to form a new basement membrane to cover the wound. On the other hand, the epidermal stem cells are activated with the proliferation and differentiation being enhanced, and the terminal differentiation and apoptosis being inhibited; and together with keratinocytes, epidermal stem cells promote the process of re-epithelialization under the regulation of various factors. In the epidermis, there is a group of resident T cell subsets, dendritic epidermal lymphocytes (DETCs) that play a key role in protecting the function of epidermal tissue. DETCs are activated after recognizing unknown antigens, the activated DETCs secret cytokines such as insulin-like growth factor â , keratinocyte growth factor-1/2, granulocyte-macrophage colony stimulating factor, interferon-γ, and transforming growth factor-ß, which promote epidermal homeostasis and re-epithelialization by regulating the dynamic balance among keratinocytes migration, proliferation, and apoptosis, and the differentiation of epidermal stem cells around the wound edge. This article discusses the biological characteristics of DETCs and their roles in the maintenance of epidermal homeostasis and wound healing.

Our previous study showed that the membrane viscosity of human umbilical vein endothelial cells (HUVECs) increased with lipopolysaccharide (LPS) concentration after direct LPS damaging, implying that LPS could change the membrane structure and composition of HUVECs. The purpose of the present study was to investigate the modification of HUVECs membrane lipid by LPS under direct LPS injury to HUVECs. Phospholipid components of HUVEC membrane were determined with high performance capillary electrophoresis (HPCE), and HUVECs were directly damaged by LPS of different concentrations: 0, 0.313, 0.625, 1.25, 2.5, 5 and 10 microgram/ml for 3 h, and by 0.625 microgram/ml for 1, 3, 6, 12, 24 and 48 h. The results show that total phospholipid content of HUVECs increased with the increase of LPS concentration at 3 h, and decreased with the duration of LPS effect at 0.625 microgram/ml. Phosphatidylinositol (PI) and phosphatidylcholine (PC) contents increased with the increase of LPS concentration and decreased with the duration of LPS effect; LPS contents and its effect duration had slight effect on sphingomyelin (SM), phosphatidylethanolamine (PE) or phosphatidylserine (PS) contents. The LPS activating effect of HUVEC membrane lipid showed a typical property of enzymatic dynamics. These experimental results indicate that LPS directly activates the metabolism of HUVEC membrane lipid and induces the modification of HUVEC membrane phospholipid, which implies that the mechanism of the impairment of HUVECs by LPS may be related to the membrane structure of HUVECs and the metabolism of HUVEC membrane lipid.
