This study explores the potential protective effects and underlying mechanisms of phosphocreatine (PCr) in the context of HI/R. We established an in vitro ischemia/reperfusion model using hepatocellular carcinoma HepG2 cells and normal liver L02 cells. For in vivo assessments, C57BL/6 mice were subjected to the HI/R model to evaluate the impact of PCr on liver protection. PCr pretreatment significantly improved liver cell survival rates, maintained mitochondrial membrane potential (MMP), reduced apoptosis, and alleviated oxidative damage and inflammatory responses. Importantly, PCr exerted its protective effects by downregulating TLR4 and activating the Akt signaling pathway, which suppressed inflammation, mitigated oxidative stress, inhibited apoptosis, and modulated key biomarkers, including ALT, AST, IL-6, IL-1β, TNF-α, SOD, MDA, and reactive oxygen species (ROS). Western blot analyses demonstrated PCr's anti-inflammatory effects through the regulation of UCP2, Cyp-D, Cyt-C, and PGC-1α, thereby preserving mitochondrial structure and function, maintaining MMP, and regulating membrane pores. Transmission electron microscopy further highlighted PCr's role in sustaining mitochondrial integrity. In conclusion, our findings suggest that PCr helps maintain mitochondrial homeostasis by intervening in the TLR4 inflammatory pathway and activating the Akt signaling pathway, ultimately reducing liver injury.

Thus, spinal and cerebral veins from five formalin-fixed human cadavers were examined through macroscopic and histological analysis, using hematoxylin, eosin and safran (HES), and orcein stains to compare them. Twenty-four cerebral veins and thirteen spinal veins were analyzed. The mean diameter of the cerebral veins was 1.02 ± 0.59 mm, while that of spinal veins was 0.52 ± 0.26 mm (p = 0.003).

In most of the analyzed vessels, the venous wall was composed of endothelial cells resting on layers of smooth muscle, separated by elastica lamina. Cerebral and spinal veins exhibit distinct calibers while maintaining comparable wall thicknesses, resulting in a greater diameter-to-thickness ratio for cerebral veins compared to spinal veins.
