AIM: To identify potential magnetic resonance imaging (MRI) biomarkers to predict the aggressiveness of endometrial cancer. MATERIALS AND METHODS: Seventy-one patients with endometrial cancer who underwent MRI staging were analysed retrospectively. The signal intensity (SI) of the tumours was assessed on sagittal T2-weighted imaging (WI) and sagittal T1WI sequences). The depth of myometrial invasion, tumour grade and subtype, lymphovascular invasion, and microsatellite stability status were assessed histopathologically, and these findings were compared with MRI findings using logistic regression...

BACKGROUND: It has been shown that intracranial atherosclerotic stenosis (ICAS) has heterogeneous features in terms of plaque instability and vascular remodeling. Therefore, quantitative information on the changes of intracranial atherosclerosis and lenticulostriate arteries (LSAs) may potentially improve understanding of the pathophysiological mechanisms underlying stroke and may guide the treatment and work-up strategies. Our present study aimed to use a novel whole-brain high-resolution cardiovascular magnetic resonance imaging (WB-HRCMR) to assess both ICAS plaques and LSAs in recent stroke patients...

BACKGROUND: Although research on pediatric intracranial aneurysms is well documented, studies of pediatric intracranial distal arterial aneurysms (PIDAAs) remain scarce. METHODS: All pediatric patients (≤ 18 years) with intracranial aneurysms located distally to the M2 segment of the middle cerebral artery (MCA), A2 segment of the anterior cerebral artery, P2 segment of the posterior cerebral artery, and other cerebral arteries distal to the main branch who were treated at our center between January 2012 and April 2017 were retrospectively reviewed...

Aldehyde dehydrogenase 2 (ALDH2) is a new therapeutic target in the central nervous system. However, the association between ALDH2 and brain edema following ischemic stroke (IS) remains unclear. The present study was investigated to whether active ALDH2 can attenuate brain edema by using a rat model of IS, with the aim of clarifying the underlying mechanisms involved. Rats were administered the ALDH2 agonist Alda-1, vehicle or the ALDH2 inhibitor cyanamide (CYA) 15 min prior to a 1.5 h middle cerebral artery occlusion (MCAO) surgery...

BACKGROUND: The skeletal muscle mass-to-visceral fat area ratio (SVR) has been linked to arterial stiffness in non-diabetic adults. We examined the association between the SVR and arterial stiffness in patients with type 2 diabetes mellitus (T2DM). METHODS: Patients with type 2 diabetes mellitus (252 men and 171 women) aged 40-75 years were enrolled and divided into three groups according to SVR tertiles. Arterial stiffness was measured as brachial-ankle pulse wave velocity (baPWV), with baPWV> 1800 mm/s defined as high...

BACKGROUND: Currently, many methodological approaches have been developed to assess peripheral endothelial function. However, a development of the noninvasive and automated technique for routinely assessing endothelial function is still required. We evaluated the potential value of a new method to measure peripheral endothelial function with reactive hyperemia peripheral arterial volume (RH-PAV) in patients with chest pain. METHODS: We used a novel oximeter-like probe to detect the peripheral arterial volume (PAV) of the finger and compared it with brachial flow-mediated dilation (FMD) performed in 93 consecutive patients with chest pain...

Our previous studies have demonstrated that the activation of the nuclear factor-kappa B (NF-κB) signaling pathway contributes to the development of lipopolysaccharide (LPS)-induced acute lung injury (ALI) as well as an inflammatory reaction, and its inhibition may provide future therapeutic values. Thereby, this study aims to explore the effects of miR-326 on inflammatory response and ALI in mice with septic shock via the NF-κB signaling pathway. The study included normal mice and LPS-induced mouse models of septic shock with ALI...

The influence of shunts between the coronary artery (CA) and the left ventricle (LV), on chest pain (CP) in patients with hypertrophic cardiomyopathy (HCM) is unknown. We examined the incidence of CA-LV shunts and their influence on CP in HCM patients. Twenty normal control subjects (NCS), 3 with CP due to CA-LV shunts (CP patients), and 60 with HCM participated. Interventricular septal wall thickness (IVST), LV posterior wall thickness (LVPWT), cardiac and stroke indexes (CI and SI), LV end-diastolic pressure (LVEDP), and proximal diameters of the CA were measured...

PURPOSE: To develop a better understanding of pediatric intracranial aneurysms (PIAs). METHODS: All PIAs treated in our center from January 2012 to April 2017 were retrospectively included. Clinical data, treatment summaries, and follow-up outcomes were retrieved and analyzed. RESULTS: A total of 66 PIAs were found in 64 patients with a mean age of 11.4 ± 5.7 years, 68.8% of whom were male. The most common symptoms were seizure (n = 7, 63...

The association of sex hormone (estradiol, testosterone, and progesterone) with cardiopulmonary disease has already attracted great attention, especially in pulmonary arterial hypertension (PAH). However, the impact of sex hormones and their pituitary stimulators (follicle-stimulating hormone and luteinizing hormone) on PAH in men remains unclear. We conducted a prospective cohort study recruiting 95 patients with idiopathic PAH from 2008 to 2014 and following up for a median of 65 months for death. Compared with control, abnormal plasma levels of sex hormones were more common in patients with PAH...

Background: Acute Ischemic Stroke (AIS) is a common cause of death worldwide and the leading cause of long-term severe disability. Endovascular bridging therapies (EBT), including endovascular thrombectomy (ET) and intra-arterial thrombolytic (IAT), have been recommended to realize a favorable functional outcome for AIS patients. Methods: An overview of meta-analyses of primary randomized controlled trial (RCT) studies was performed evaluating EBT for AIS patients compared with usual care...

PURPOSE: Hemodilutional anemia is associated with acute kidney injury (AKI) and mortality in patients undergoing cardiac surgery by mechanisms that may include tissue hypoxia. Our hypothesis was to assess if changes in the potential hypoxic biomarkers, including methemoglobin and erythropoietin, correlated with a decrease in hemoglobin (Hb) concentration following hemodilution on cardiopulmonary bypass (CPB). METHODS: Arterial blood samples were taken from patients (n = 64) undergoing heart surgery and CPB at baseline, during CPB, following CPB, and in the intensive care unit (ICU)...

BACKGROUND AND AIMS: Recent studies have suggested that heat shock protein 70 (HSP70) may play critical roles in cardiovascular disease. However, the effects of HSP70 on the development of atherosclerosis in apoE-/- mice remain largely unknown. This study was to investigate the role and potential mechanism of HSP70 in atherosclerosis. METHODS: HSP70 was overexpressed in apoE-/- mice and THP-1-derived macrophages with lentiviral vectors. Oil Red O, hematoxylin-eosin, and Masson staining were performed to evaluate atherosclerotic plaque in apoE-/- mice fed the Western type diet...

BACKGROUND: Hypoxic pulmonary arterial hypertension (PAH) is a crippling disease with limited therapeutic methods. The imbalance of T helper 17 cell (Th17)/regulatory T cell (Treg) plays an important role in the development of Hypoxic PAH. However, whether targeting the ras homolog family member A-Rho kinase (RhoA-ROCK) pathway (activation and inhibition) by lysophosphatidic acid (LPA) and fasudil (FSD) regulate T-cell homeostasis in Hypoxic PAH remain unknown. OBJECTIVE: To examine the effects of LPA and FSD on hypoxic pulmonary vascular remodeling and homeostasis of Th17/Treg cells in Hypoxic PAH...

BACKGROUND: It remains unknown whether Non-POU-domain-containing octamer-binding protein (NonO) plays a causative role in plaque destabilization. We hypothesized that NonO gene silencing may stabilize atherosclerotic plaque by increasing P4Hα1 expression and inhibiting the inflammation. METHODS AND RESULTS: Vulnerable atherosclerotic plaques were induced in ApoE-/- mice by high fat diet, perivascular collar placement and mental stress. Compared with normal carotid arteries, those contained vulnerable plaques had high NonO expression...
