Purpose: Aortic dissection (AoD) is one of the most common catastrophes involving the aorta. Nevertheless, early diagnosis remains to be a challenge in the Emergency Department (ED), particularly in young individuals. In this study, we attempted to identify the characteristics of acute AoD among young individuals, particular in patients with Marfan syndrome. Materials and Methods: This was an retrospective chart-review study conducted in a tertiary referring hospital. The hospital database was queried for the combination of AoD and patients under age of 40 years. The medical charts were reviewed to obtain demographic data, clinical data and laboratory characteristics by using a standardized data collection sheet. A comparison between Marfan syndrome and non-Marfan syndrome patients was performed. Results: During the 10- years period, 18 of 344 patients with acute AoD were younger than 40 years-old. Patients with Marfan syndrome developed acute AoD at a younger age than patients without Marfan syndrome. The mean diastolic blood pressure was significantly lower in patients with Marfan syndrome upon presenting to the ED than those without. Patients with Marfan syndrome had trends toward higher risk of development of type A AoD, increased recurrence rate and higher mortality rate than those without. However, statistical significance was not present. Conclusion: ED physicians should have high alert to acute AoD in young patients presenting with severe unexplained chest and back pain, particularly in those patients with a history of heart diseases, hypertension, and Marfan syndrome or featuring Marfanoid habitus. Acute coronary syndrome, unexplained abdominal symptoms, and sudden cardiac arrest could be the initial manifestation of AoD in young patients. A low threshold to perform enhanced computed tomography may facilitate early diagnosis and timely treatment in this patient population.

Hepatic ischemia/reperfusion (IR) injury is a complication that occurs during liver surgery, whereby hepatic tissue is injured by oxygen deficiency during ischemia, then further damaged by a cascade of inflammatory and oxidative insults when blood is resupplied during reperfusion. Antrodia camphorata is an indigenous fungus in Taiwan and an esteemed Chinese herbal medicine with various bioactivities. This study examined the effect of ergostatrien-3β-ol (EK100), an active compound found in both the fruiting body and mycelia of A. camphorata, on IR injury pathologies in rats and cell models of oxidative and inflammatory stress. Male Sprague-Dawley rats were randomly assigned to receive a vehicle or 5 mg/kg EK100 prior to hepatic IR injury induced by 1 h ischemia followed by 24 h reperfusion, or a sham operation. RAW 264.7 murine macrophages and HepG2 hepatocytes were pretreated with EK100, then inflammation was induced with lipopolysaccharides in the former and oxidative stress was induced with hydrogen peroxide in the latter. EK100 decreased IR-induced elevation in serum levels of alanine aminotransferase and aspartate aminotransferase and lowered levels of the inflammatory cytokines tumor necrosis factor-α, interleukin (IL)-6, and IL-1β. In addition, EK100 significantly reduced hepatic mRNA levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2, as well as nitrite production and iNOS gene expression in both hepatocyte and macrophage cell lines. We demonstrated that EK100 exhibits potent protection against hepatic IR injury, which may be used to design strategies to ameliorate liver damage during liver surgery.
