Objective: To evaluate the clinical effect of a subspecialty standardized temperature management process in a hybrid surgery for treating acute aortic dissection.

Methods: From January 2020 to June 2021, 102 patients who underwent hybrid surgery for acute aortic dissection in the Department of Cardiovascular Surgery at the Huai'an First People's Hospital were selected as the control group, receiving routine temperature maintenance measures. From August 2021 to November 2022, 105 similar patients from the same hospital were enrolled in the experimental group, where a subspecialty standardized temperature management process was implemented.

Objective: To determine whether a transesophageal echocardiography (TEE) probe can accurately measure temperature and be used to monitor temperature changes over time without overheating in an experimental model of hypothermia and rewarming.

Methods: A 6L water bath was heated with a sous vide immersion circulator to 24C, 28C, 32C and 36C to simulate severe hypothermia, moderate hypothermia, mild hypothermia, and normothermia. A TEE probe, esophageal temperature probe, and bladder temperature probe were used to measure temperature.

: Research on the roles of stem cells in necrotizing enterocolitis (NEC) has primarily focused on the effects of bone marrow- and amniotic fluid-derived stem cells in mitigating the clinical manifestations of the disease. However, the potential of adipose tissue-derived stem cells (ADSCs) remains unexplored in this context. The aim of this study was to evaluate the therapeutic potential of ADSC administration during the active inflammatory phase of NEC, with a specific focus on reducing the levels of the inflammatory cytokines IL-1 and IL-6.

Hydrogen sulfide (HS) is a gasotransmitter that modulates vascular tone, causing either vasodilation or vasoconstriction depending on the vascular bed, species, and experimental conditions. The cold-sensitive transient receptor potential ankyrin-1 (TRPA1) channel mediates HS-induced effects; however, its contribution to the vasomotor responses of different arteries at different temperatures has remained unclear. Here, we aimed to fill this gap by comparing the effects of sodium sulfide (NaS), which is a fast-releasing HS donor, on the isolated carotid and tail skin arteries of rats and mice at cold and normal body temperature with wire myography.

Remote ischemic conditioning (RIC) has attracted considerable attention as a brain protection strategy, although its impact remains unclear. Hypothermia is the most effective strategy in experimental transient cerebral ischemia. Therefore, we compared the efficacy of RIC, hypothermia, and no treatment on cerebral ischemia.
