The aortic medial degeneration is the key histopathologic feature of Thoracic aortic dissection (TAD). The aim of this study was to identify the change of autophagic activity in the aortic wall during TAD development, and to explore the roles of autophagy on regulating functional properties of smooth muscle cells (SMCs). Firstly, compared with control group (n = 11), the increased expression of autophagic markers Beclin1 and LC3 was detected in the aortic wall from TAD group (n = 23) by immunochemistry and western blot...

ADAMTS13 is a von Willebrand factor-cleaving protease. The mutant types of p.P475S (c.1423C>T) polymorphism in ADAMTS13 have a reduced activity in comparison with the wild type. In the present study, we investigated the frequency of the C-to-T substitution in 2584 genomic DNA samples from 25 Asian, European, and African populations using APLP (amplified product length polymorphism) and/or HRM (high-resolution melting) assays. Allele T (ADAMTS13(∗)T) was detected only in Asian populations and its frequency was observed to decrease gradually from north to south in 24 East Asian populations...

Objective A fever is observed in approximately one-third of cases of acute aortic dissection (AAD); however, the causes remain unclear. We investigated the mechanism of a fever in AAD by measuring the serum concentrations of inflammatory markers, mediators of coagulation and fibrinolysis, and procalcitonin, a marker of bacterial infection. Methods We retrospectively studied 43 patients with medically treated AAD without apparent infection. Patients were divided into those with (Group A; n=19) and without (Group B; n=24) a maximum body temperature >38°C...

Objective Admission D-dimer and C-reactive protein (CRP) values have been reported to predict the short-term outcomes in acute aortic dissection (AAD). However, the association between D-dimer values and the long-term outcomes has not been investigated. Methods The primary endpoints included events determined to be all-cause death, recurrence of aortic dissection, aortic rupture, and surgical intervention for the aortic aneurysm following the first hospital discharge. We performed a receiver operating characteristic analysis and determined the optimal cut-off levels of admission D-dimer, admission CRP and peak CRP values in terms of the sensitivity and specificity for predicting the presence of events...

INTRODUCTION: /Objectives: Acute aortic dissection (AAD) can cause limb ischemia due to branch vessel occlusion. A minority of patients have persistent ischemia after central aortic repair and require peripheral arterial revascularization. We investigated whether the need for limb revascularization is associated with adverse outcomes. METHODS: We reviewed our cases of AAD from 2000 to 2014 and identified patients with malperfusion syndromes (coronary, cerebral, spinal, visceral, renal, or peripheral ischemia)...

Marfan syndrome (MFS) is a pleiotropic connective tissue disease inherited as an autosomal dominant trait, due to mutations in the FBN1 gene encoding fibrillin 1. It is an important protein of the extracellular matrix that contributes to the final structure of a microfibril. Few cases displaying an autosomal recessive transmission are reported in the world. The FBN1 gene, which is made of 66 exons, is located on chromosome 15q21.1. This review, after an introduction on the clinical manifestations that leads to the diagnosis of MFS, focuses on cardiovascular manifestations, pharmacological and surgical therapies of thoracic aortic aneurysm and/or dissection (TAAD), mechanisms underlying the progression of aneurysm or of acute dissection, and biomarkers associated with progression of TAADs...

Acute cardiothoracic and respiratory diseases frequently remain a challenge to diagnose and differentiate in the emergency setting. The main diseases that manifest with chest pain include ischaemic heart disease, myocarditis, acute pericarditis, aortic dissection/rupture and pulmonary embolism (PE). Diseases that primarily present with dyspnoea include heart failure (HF), acute respiratory distress syndrome (ARDS), pneumonia, asthma exacerbations and chronic obstructive pulmonary disease. Pre-test probabilities of clinical findings play a vital part in diagnostic decisions, and the use of a Bayesian approach to these greatly improves the ability to stratify patients more accurately...

BACKGROUND AND PURPOSE: Patients with acute aortic dissection (AAD) sometimes present predominantly with neurological symptoms from cerebral ischemia. Such stroke patients must not receive thrombolysis therapy, which can be fatal. However, patients remain at risk if there is a failure to notice concurrent AAD. We aimed to clarify the characteristics of AAD patients with stroke to identify markers for early AAD detection before thrombolysis. METHODS: Using the single-center database of Stanford type A-AAD patients between 2007 and 2013, we selected those presenting with acute focal neurological deficits, presumably due to cerebral ischemia...

In patients with cancer of the pancreatic head, metastasis to para-aortic lymph nodes (LN16) is considered distant metastasis and a poor prognostic marker. However, the incidence of LN16 involvement in pancreatic head cancer is high, and it is unclear whether all such patients have poor surgical outcomes. We investigated the significance of LN16 involvement in resectable pancreatic head cancer by retrospectively analyzing 579 ductal adenocarcinoma patients treated with para-aortic lymph node dissection at two high-volume Chinese centers...

BACKGROUND: αVβ3-integrin is expressed by activated endothelial cells and macrophages in atherosclerotic plaques and may represent a valuable marker of high-risk plaques. We evaluated (99m)Tc-maraciclatide, an integrin-specific tracer, for imaging vascular inflammation in atherosclerotic lesions in mice. METHODS: Apolipoprotein E-negative (ApoE(-/-)) mice on a Western diet (n = 10) and normally fed adult C57BL/6 control mice (n = 4) were injected with (99m)Tc-maraciclatide (51...

OBJECTIVES: Resveratrol (RES) is a polyphenol compound that has been shown a promising cardioprotective effect. However, some reports have yielded conflicting findings. Herein, we investigated the anti-atherosclerotic effects of RES in apolipoprotein E (apo E)-deficient mice on a high cholesterol diet. MATERIALS AND METHODS: Firstly, atherosclerosis was induced by feeding a high cholesterol diet to apo E-deficient mice. Then, we examined its effects on weight control, and serum interleukin-6 (IL-6) levels and used histopathological methods to analyze morphology and inflammatory marker of atherosclerotic lesions in mice orally supplemented with high (25 mg/kg/day) and low (5 mg/kg/day) doses of RES for 8 weeks...

BACKGROUND: Thoracic aortic aneurysm is usually a clinically silent disease; timely detection is largely dependent upon identification of clinical markers of thoracic aortic disease (TAD); (bicuspid aortic valve, intracranial aortic aneurysm, bovine aortic arch, or positive family history). Recently, an association of simple renal cysts (SRC) with abdominal aortic aneurysm and aortic dissection was established. The aim of our study was to evaluate the prevalence of SRC in patients with TAD in order to assess whether the presence of SRC can be used as a predictor of TAD...
