Abstract
Traumatic brain injury (TBI) produces excess iron, and increased iron accumulation in the brain leads to lipid peroxidation and reactive oxygen species (ROSs), which can exacerbate secondary damage and lead to disability and death. Therefore, inhibition of iron overload and oxidative stress has a significant role in the treatment of TBI. Functionalized hydrogels with iron overload inhibiting ability and of oxidative stress inhibiting ability will greatly contribute to the repair of TBI. Herein, an injectable, post-traumatic microenvironment-responsive, ROS-responsive hydrogel encapsulated with deferrioxamine mesylate (DFO) was developed. The hydrogel is rapidly formed via dynamic covalent bonding between phenylboronic acid grafted hyaluronic acid (HA-PBA) and polyvinyl alcohol (PVA), and phenylboronate bonds are used to respond to and reduce ROS levels in damaged brain tissue to promote neuronal recovery. The release of DFO from HA-PBA/PVA hydrogels in response to ROS further promotes neuronal regeneration and recovery by relieving iron overload and thus eradicating ROS. In the Feeney model of Sprague Dawley rats, HA-PBA/PVA/DFO hydrogel treatment significantly improved the behavior of TBI rats and reduced the area of brain contusion in rats. In addition, HA-PBA/PVA/DFO hydrogel significantly reduced iron overload to reduce ROS and could effectively promote post-traumatic neuronal recovery. Its effects were also explored, and notably, HA-PBA/PVA/DFO hydrogel can reduce iron overload as well as ROS, thus protecting neurons from death. Thus, this injectable, biocompatible and ROS-responsive drug-loaded hydrogel has great potential for the treatment of TBI. This work suggests a novel method for the treatment of secondary brain injury by inhibiting iron overload and the oxidative stress response after TBI.

Abstract
Deep tissue injuries (DTIs) are a serious type of pressure injuries that mainly occur at the bony prominences and can develop rapidly, making prevention and treatment more difficult. Although consistent research efforts have been made over the years, the cellular and molecular mechanisms contributing to the development of DTIs remain unclear. More recently, ferroptosis, a novel regulatory cell death (RCD) type, has been identified that is morphological, biochemical and genetic criteria distinct from apoptosis, autophagy and other known cell death pathways. Ferroptosis is characterized by iron overload, iron-dependent lipid peroxidation and shrunken mitochondria. We also note that some of the pathological features of DTI are known to be key features of the ferroptosis pathway. Numerous studies have confirmed that ferroptosis may be involved in chronic wounds, including DTIs. Here, we elaborate on the basic pathological features of ferroptosis. We also present the evidence that ferroptosis is involved in the pathology of DTIs and highlight a future perspective on this emerging field, desiring to provide more possibilities for the prevention and treatment of DTIs.

Abstract
Traumatic brain injury (TBI) is one of the main factors of death and disability in adults with a high incidence worldwide. Nervous system injury, as the most common and serious secondary injury after TBI, determines the prognosis of TBI patients. NAD+ has been confirmed to have neuroprotective effects in neurodegenerative diseases, but its role in TBI remains to be explored. In our study, nicotinamide mononucleotides (NMN), a direct precursor of NAD+, was used to explore the specific role of NAD+ in rats with TBI. Our results showed that NMN administration markedly attenuated histological damages, neuronal death, brain edema, and improved neurological and cognitive deficits in TBI rats. Moreover, NMN treatment significantly suppressed activated astrocytes and microglia after TBI, and further inhibited the expressions of inflammatory factor. Besides, RNA sequencing was used to access the differently expressed genes (DEGs) and their enriched (Kyoto Encyclopedia of Genes and Genomes) KEGG pathways between Sham, TBI, and TBI+NMN. We found that 1589 genes were significantly changed in TBI and 792 genes were reversed by NMN administration. For example, inflammatory factor CCL2, toll like receptors TLR2 and TLR4, proinflammatory cytokines IL-6, IL-11 and IL1rn which were activated after TBI and were decreased by NMN treatment. GO analysis also demonstrated that inflammatory response was the most significant biological process reversed by NMN treatment. Moreover, the reversed DEGs were typically enriched in NF-Kappa B signaling pathway, Jak-STAT signaling pathway and TNF signaling pathway. Taken together, our data showed that NMN alleviated neurological impairment via anti-neuroinflammation in traumatic brain injury and the mechanisms may involve TLR2/4-NF-κB signaling.
