Objective: To analyze the blood supply and metabolism in the marginal area of foci of hepatic alveolar echinococcosis by quantitative perfusion parameters.
Methods: Thirty patients with hepatic alveolar echinococcosis were scanned with the Revolution CT and the images were analyzed. The perfusion parameters, such as the bloodflow (BF), time to peak (TTP), blood volume (BV), mean transit time (MTT) and hepatic arterial fraction (HAF) were compared among different groups.
Results: The BF, TTP, BV and MTT values of the peripheral infiltration zone and the values of the surrounding normal liver tissues were significantly different ( = 24.579, 8.343, 20.535 and 21.843, all <0.05), but the HAF values of the peripheral infiltration zone and the values of the surrounding normal liver tissues were not significantly different in the hepatic alveolar echinococcosis patients ( = 2.621, > 0.05) .
Conclusions: The whole hepatic perfusion Revolution CT can accurately and quantitatively analyze the alveolar echinococcosis foci, especially the peripheral infiltration zone, which has important guiding significance for the formulation of surgical plan.

The role of chromatin biology and epigenetics in disease progression is gaining increasing recognition. Genes that escape X chromosome inactivation (XCI) can impact neuroinflammation through epigenetic mechanisms. Our previous study has suggested that the X escapee genes Kdm6a and Kdm5c are involved in microglial activation after stroke in aged mice.

Despite identifying specific CD8 T cell subsets associated with immunotherapy resistance, the molecular pathways driving this process remain elusive. Given the potential role of CD38 in regulating CD8 T cell function, we aimed to investigate the accumulation of CD38CD8 T cells in lung cancer and explore its role in immunotherapy resistance. Phenotypic analysis of tumoral CD8 T cells from both lung cancer patients and immunotherapy-resistant preclinical models revealed that CD38-expressing CD8 T cells consist of CD38 and CD38 subsets.

Background: Anti-amyloid-β (Aβ) immunotherapy trials have shown amyloid-related imaging abnormalities (ARIA) as the most common and serious adverse events linked to pathological changes in cerebral vasculature. Nevertheless, the mechanisms underlying how amyloid immunotherapy triggers vascular damage, increases vascular permeability, and results in microhemorrhages remains unclear. Notably, activation of perivascular macrophages and infiltration of peripheral immune cells have been implicated in regulating cerebrovascular damage.

Background: The brain is shielded from the peripheral circulation by central nervous system (CNS) barriers, comprising the well-known blood-brain barrier (BBB) and the less recognized blood-cerebrospinal fluid (CSF) barrier located within the brain ventricles. The gut microbiota represents a diverse and dynamic population of microorganisms that can influence the health of the host, including the development of neurological disorders like Alzheimer's disease (AD). However, the intricate mechanisms governing the interplay between the gut and brain remain elusive, and the means by which gut-derived signals traverse the CNS barriers remain unclear.

Most of advanced non-small cell lung cancer (NSCLC) patients will experience tumor progression with immunotherapy (IO). Preliminary data suggested an association between high plasma HGF levels and poor response to IO in advanced NSCLC. Our study aimed to evaluate further the role of the HGF/MET pathway in resistance to IO in advanced NSCLC.
