Hypoxic/ischemic brain damage is well-known catastrophic injury. The specific treatment, socalled neuroprotective therapy, aims to prevent or diminish this havoc damage. However, approved neuroprotective therapy in clinical practice is limited. Targeted temperature management (TTM) shows the most promising neuroprotective therapy. Moreover, TTM is also useful for intracranial pressure (ICP) control. Many methods of TTM have been reported. TTM can apply to several clinical conditions associated with hypoxic/ischemic brain injury or elevated intracranial pressure.

PURPOSE: The purpose of this study was to determine the characteristics of hypoxic-ischemic encephalopathy (HIE) on diffusion-weighted imaging (DWI) and the role of DWI for the diagnosis of HIE. MATERIALS AND METHODS: Six patients with HIE underwent MRI including DWI. MR examinations were performed within 4 - 32 days (mean, 11.8 days) after hypoxic brain insult. We assessed the distribution of the lesions and compared the DWI and T2, FLAIR images for the subjective conspicuity of the lesions. RESULTS: In all patients, symmetrical hyperintense lesions were demonstrated in the bilateral basal ganglia on T2, FLAIR, and DWI. On ADC map image, the lesions were hypointense in four of six patients and isointense in other two patients. Lesion conspicuity on DWI was higher than on T2 and FLAIR images in four of six patients and similar in other two patients. For the involvement of the cortex and subcortical white matter, in five of six patients, bilateral symmetric hyperintense lesions were seen on T2, FLAIR, and DWI. Lesion conspicuity on DWI was higher than on T2 and FLAIR images in three of them and similar in other two patients. On ADC map image, the lesions showed hypointensity in three of five patients and isointensity in other two patients. For the involvement of the deep cerebral white matter, T2, FLAIR, and DWI showed bilateral symmetric hyperintense lesions in four of six patients. Among them, Lesion conspicuity on DWI was higher than on T2 and FLAIR images in only one patient. CONCLUSION: HIE is characterized by symmetrical hyperintense lesions in the bilateral basal ganglia, cerebral cortex, and white matter on DWI and the lesions are more conspicuously demonstrated on DWI than on T2 and FLAIR images.

Autophagy is a highly evolutionarily conserved physiological mechanism of organism, including several stages such as autophagosomes formation, the fusion of lysosomes and autophagosomes, and autophagosomes degradation. In physiological conditions, autophagy is responsible for clearing the spoiled organelles and long-lived proteins to maintain the homeostasis of cells and organism. Meanwhile, autophagy is also involved in the formation and development of diseases, but the mechanism has not been confirmed yet. The relationship between autophagy and hypoxic ischemic brain injuries represented by stroke is a research hotpot in recent years, but there is no clear conclusion about autophagy's role and mechanism in hypoxic ischemic brain injuries. We reviewed the activation, function and mechanism of autophagy in hypoxic ischemic brain injuries, in order to provide some perspectives on these researches.
