Bacterial infection and oxidative stress are serious complications in emergency burn patients, as the increase of oxygen free radicals in burn wounds can aggravate vascular endothelial cell injury, make the wounds ischemic and hypoxic, and delay wound healing. Traditional dressings cannot meet the first-aid needs of burn patients. In this study, polycaprolactone/chitosan (PCL/CS) was used as an electrospun nanofiber matrix, and curcumin (CUR), a molecule with excellent anti-inflammatory and antioxidant properties, was introduced to construct polycaprolactone/ chitosan graft copolymer-zein-curcumin electrospun nanofibers (PCL/CS-ZE-CUR). The results of clinical experiments suggest that compared with traditional dressings, based on the excellent mechanical properties and antibacterial activity of PCL/CS, the new dressing can exhibit oxygen free radical-scavenging abilities of CUR to accelerate wound healing and is expected to provide a beneficial upgrade for wound emergency care.

This study was aimed at exploring the new management mode of medical information processing and emergency first aid nursing management under the new artificial intelligence technology. This study will use the artificial intelligence algorithm to optimize medical information processing and emergency first aid nursing management process, in order to improve the efficiency of emergency department and first aid efficiency. The successful rescue rates of hemorrhagic shock, coma, dyspnea, and more than three organs injury were 96.7%, 92.5%, 93.7%, and 87.2%, respectively, after the emergency first aid nursing mode was used in the hospital emergency center. The success rates of first aid within three years were compared, which were 91.8%, 93.4%, and 94.2%, respectively, showing an increasing trend year by year. 255 emergency patients in five batches in June and five batches in July were selected as the research objects by convenience sampling method. Among them, 116 cases in June were taken as the experimental group, and 139 cases in July were taken as the control group, which was used to verify the efficiency of the design model in this study. The results showed that the triage time of the two groups was 8.16 ± 2.07  min and 19.21 ± 6.36  min, respectively, and the difference was statistically significant ( P < 0.01 ). The triage coincidence rates were 96.35% and 90.04%, respectively, and the difference was statistically significant ( P < 0.05 ). The research proved that the design of intelligent medical information processing and emergency first aid nursing management research model can effectively improve the triage efficiency of the wounded, assist the efficiency of emergency nursing of medical staff, and improve the survival rate of emergency patients, which is worthy of clinical promotion.

The use of lignocellulosic natural fibres has gained a growing interest during the last few years, principally due to many advantages these fibres can provide in terms of cost, renewability, biodegradability, aesthetic properties, environmental impact etc. Keeping in mind the immense advantages of natural fibres, the present communication is a study on the synthesis and characterization of lignocellulosic Saccaharum cilliare fibre-reinforced polymer biocomposites through compression-moulding technique using phenol-formaldehyde (PF) resin as anovel polymer matrix. The effect of fibre loading on the mechanical, morphological and thermal properties of cellulose fibre reinforced biocomposites has been investigated. Mechanical properties such as tensile strength, flexural strength, compressive strength and wear resistance of fibre-reinforced polymer composites have been investigated as a function of fibre loading. Reinforcing of the polymer resin with lignocellulosic fibres was done in the particle (200 micron) form. The intact polymer biocomposites fabricated showed a common trend of enhancement in the mechanical properties with fibre loadings up to 30%, and beyond this loading the properties decreased. Fibre/matrix interaction has been analyzed by mechanical and morphological (SEM) studies. Thermal (TGA/ DTA/ DTG) studies have also been carried out on the PF matrix, Saccaharum ciliare fibre and particle-reinforced (P-Rnf) biocomposites.
