Hepatic encephalopathy is a common and serious complication of end-stage liver diseases such as liver cirrhosis， and it is basically a neuropsychiatric syndrome resulting from metabolic disorders caused by severe acute or chronic liver dysfunction or portosystemic shunt. In clinical practice， the onset of hepatic encephalopathy does not completely correlate linearly with the level of blood ammonia and is often triggered by extrahepatic factors， suggesting the presence of complex multiorgan crosstalk in the pathogenesis of hepatic encephalopathy. Based on the four main pathogeneses of ammonia toxicity， inflammation， neurotransmitter imbalance， and oxidative/nitrosative stress， this article systematically elaborates on the mechanism of multiorgan crosstalk in hepatic encephalopathy and discusses the emerging risk factors such as sarcopenia and diabetes mellitus， in order to provide a novel theoretical framework for deepening the understanding of the pathophysiological mechanisms of hepatic encephalopathy and formulating clinical diagnosis and treatment strategies in the future.

Objective:To investigate the impact of blood pressure outcomes on the risk of arteriosclerosis in non-hypertensive populations.Methods:This study was a retrospective cohort study. All data were derived from Kailuan Cohort. Non-hypertensive individuals who completed two brachial-ankle pulse wave velocity (baPWV) measurements between January 2014 and December 2019 (using the first measurement as the baseline and the second as the follow-up) were enrolled, and clinical data such as blood pressure and baPWV were collected. According to the blood pressure level at baseline and follow-up, participants were divided into new-onset hypertension group (no hypertension at baseline but diagnosed at follow-up) and non-hypertension group (no hypertension at both baseline and follow-up). Multiple linear regression and multivariate logistic regression were used to analyze the impact of new-onset hypertension on arteriosclerosis progression. Subgroup analysis further classified participants into six blood pressure transition categories: normal-maintained, normal-to-high-normal, normal-to-hypertensive, high-normal-to-normal, high-normal-maintained, and high-normal-to-hypertensive groups. Multivariate logistic regression analysis was used to assess the impact of different blood pressure outcomes on arteriosclerosis progression.Results:A total of 7 049 participants were enrolled, with the age of (40.45±9.04) years, including 3 645 males (51.71%). There were 800 cases in the new-onset hypertension group and 6 249 individuals in the non-hypertension group. During follow-up, arteriosclerosis occurred in 2 154 cases (30.56%). Multivariable linear regression analysis revealed a positive correlation between new-onset hypertension and baPWV levels. The baPWV in the new-onset hypertension group was significantly higher by 63.94 cm/s compared to the non-hypertension group ( β=63.94, P<0.01). Additionally, the risk of arteriosclerosis in the new-onset hypertension group was 2.09 times that of the non-hypertension group ( OR=2.09, 95% CI: 1.77-2.46, P<0.01). Subgroup analysis revealed significantly higher arteriosclerosis risks in normal-to-high-normal ( OR=1.65, 95% CI 1.38-1.98, P<0.01), normal-to-hypertensive ( OR=2.47, 95% CI 1.70-3.59, P<0.01), high-normal-maintained ( OR=1.50, 95% CI 1.21-1.86, P<0.01), and high-normal-to-hypertensive groups ( OR=2.86, 95% CI 2.20-3.73, P<0.01) than normal-maintained group, except for a non-significant difference in high-normal-to-normal group ( OR=0.95, 95% CI 0.74-1.20, P>0.05). Conclusion:Blood pressure outcome in non-hypertensive populations is closely related to arteriosclerosis risk. Progression to or maintenance of high-normal blood pressure or higher levels substantially increases arteriosclerosis risk, while regression from high-normal to normal blood pressure shows no significant increase in arteriosclerosis risk.
