Radiomics in Carotid Plaque: A Systematic Review and Radiomics Quality Score Assessment.

Imaging modalities provide information on plaque morphology and vulnerability; however, they are operator dependent and miss a great deal of microscopic information. Recently, many radiomics models for carotid plaque that identify unstable plaques and predict cardiovascular outcomes have been proposed. This systematic review was aimed at assessing whether radiomics is a reliable and reproducible method for the clinical prediction of carotid plaque.

Alkaloid Derivative ()-3β-Ethylamino-Pregn-17(20)-en Inhibits Triple-Negative Breast Cancer Metastasis and Angiogenesis by Targeting HSP90α.

Metastasis is an important cause of cancer-related death. Previous studies in our laboratory found that pregnane alkaloids from had antimetastatic activity against breast cancer cells. In the current study, we demonstrated that treatment with one of the alkaloid derivatives, ()-3β-ethylamino-pregn-17(20)-en (), led to the downregulation of the HIF-1α/VEGF/VEGFR2 pathway, suppressed the phosphorylation of downstream molecules Akt, mTOR, FAK, and inhibited breast cancer metastasis and angiogenesis both in vitro and in vivo.

Rational Design of Quinoxalinone-Based Red-Emitting Probes for High-Affinity and Long-Term Visualizing Amyloid-β In Vivo.

Alzheimer's disease (AD) is a progressive neurodegenerative disease with insidious onset, and the deposition of amyloid-β (Aβ) is believed to be one of the main cause. Fluorescence imaging is a promising technique for this task, but the Aβ gold standard probe ThT developed based on this still has shortcomings. The development of a new fluorescent probe to detect Aβ plaques is thought to be essential.

Prevalence of recommended anticoagulation by guidelines preadmission and its impact on the incidence of acute myocardial infarction (AMI) and in-hospital outcomes after AMI in atrial fibrillation patients.

This study was designed to explore the prevalence of recommended anticoagulation by guidelines before admission and its impact on the incidence of acute myocardial infarction (AMI) and the AMI associated in-hospital outcomes in patients with atrial fibrillation (AF). 10,725 patients with AF at their first hospitalizations in our hospitals were retrospectively reviewed, with a prevalence of recommended anticoagulation preadmission 24.41% (Number = 2618).

Discovery of an Ultra-rapid and Sensitive Lysosomal Fluorescence Lipophagy Process.

Non-invasive dynamic tracking of lysosomes and their interactions with other organelles is important for the study of lysosomal function and related diseases. However, many fluorescent dyes developed so far to target lysosomes cannot be used to monitor these processes due to the high concentrations required for imaging, long cell penetration times, and non-ideal photostability. In this regard, we synthesized three lysosomal targeting probes with large Stokes shifts, good stability, and high brightness.

Discovery of Antimetastatic Chiral Ionone Alkaloid Derivatives Targeting HIF-1α/VEGF/VEGFR2 Pathway.

Novel chiral ionone alkaloid derivatives were synthesized and their antimetastatic effects were evaluated in human breast cancer cells using chemotaxis assay. Compared with positive control LY294002, a PI3 K inhibitor, derivatives 10 a, 11 a, 11 c, 11 g, 11 j, 11 k and 11 w exhibited significant inhibitory effects against cancer cell migration. Especially, the IC for compound 11 g was as low as 0.

Patients with acute myocardial infarction and atrial fibrillation: association of anaemia with risk of in-hospital bleeding, stroke and other death causes.

Purposes: To explore the association of anaemia with risk of outcomes of in-hospital patients with acute myocardial infarction (AMI) and atrial fibrillation (AF).

Methods: Patients with AF and AMI at their first hospitalizations in three hospitals (Beijing Tongren Hospital, Beijing Friendship Hospital, Capital Medical University and China-Japan Friendship Hospital) were retrospectively reviewed and divided into two groups (with vs. without anaemia) according to haemoglobin within one day before or after admission.

The relationship among social capital, eHealth literacy and health behaviours in Chinese elderly people: a cross-sectional study.

Background: Social capital has been linked to health behaviours, but the underlying mechanism is unclear. Previous studies have found that health literacy played the role of a mediator in the relationships among social capital, individual physical activity and nutrition. But it is not clear whether eHealth literacy mediates the impact of social capital on health behaviours.

Elevated triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio increased risk of hyperuricemia: a 4-year cohort study in China.

Purpose: Previous studies revealed that high serum uric acid (SUA) levels correlated with increased triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio. However, evidence is lacking regarding whether TG/HDL-C is an independent risk factor or just a simple marker of hyperuricemia. We aimed to investigate the relationship between TG/HDL-C and the risk of hyperuricemia in Chinese population.

Global identification of alternative splicing in Shiraia bambusicola and analysis of its regulation in hypocrellin biosynthesis.

Hypocrellins, as natural pigments from Shiraia bambusicola, have extensive applications in the agricultural, cosmetic, food, and feed industries, and play a vital role in photodynamic therapy for anticancer and antiviral treatments. However, environmental stresses are always the bottlenecks for increasing hypocrellin yield during the process of fermentation. Pre-mRNA alternative splicing (AS) is an essential mechanism in the defense of abiotic stresses in the animal and plant kingdom, but is seldom involved in fungi.

Membranous subaortic stenosis coexisting with hypertrophic cardiomyopathy: A case report.

Subaortic stenosis (SAS) is a congenital heart disease, and its association with hypertrophic cardiomyopathy is very rare and clinically underappreciated. We report here a case of a 45-year-old female who was admitted to our hospital with chest tightness and shortness of breath. Both transthoracic and transesophageal echocardiography revealed asymmetric left ventricular hypertrophy and a membrane-like echo below the level of the aortic valve.

Differences of Matrix Metalloproteinase 2 Expression between Left and Right Ventricles in Response to Nandrolone Decanoate and/or Swimming Training in Mice.

Background: Matrix metalloproteinase (MMP)-2 plays an important role in the remodeling of left ventricles (LVs) and right ventricles (RVs). We investigated the differences of MMP-2 expression between LV and RV in response to nandrolone decanoate (ND), swimming training (ST), and combined ND and ST (NS) in mice, based on their structural, functional, and biochemical characteristics.

Methods: Totally 28 male C57B1 mice (6 weeks old; 20-23 g) were divided into four groups, including the control (n = 7), ND (n = 6), ST (n = 8), and NS (n = 7) groups.

High-efficiency biosynthesis of hypocrellin A in Shiraia sp. using gamma-ray mutagenesis.

Hypocrellin A (HA), well known as one of the best natural pigments and bioactive agent to treat skin diseases, is further anticipated to play a vital role in photodynamic therapy (PDT) in anticancer and antiviral treatments. In this study, an HA-producing strain ZZZ816 (Shiraia sp.) was isolated from the moso bamboo (Phyllostachys edulis) seeds, and gamma irradiation was used to mutagenize spores of the original strain.

Value of Neutrophil Counts in Predicting Surgery-Related Acute Kidney Injury and the Interaction of These Counts With Diabetes in Chronic Kidney Disease Patients With Hypertension: A Cohort Study.

As a component of routine blood cell analyses, the quantity of neutrophils present is a proven predictor of morbidity and mortality in several clinical settings. However, whether episodes of acute kidney injury (AKI) are associated with higher neutrophil counts in vulnerable groups, such as chronic kidney disease (CKD) patients with hypertension, are unknown. This study was conducted to investigate the relationship between neutrophil counts and the incidence of surgery-related AKI in CKD patients with hypertension.

Safety of antithrombotic drugs in patients with atrial fibrillation and non-end-stage chronic kidney disease: Meta-analysis and systematic review.

Objective: To evaluate the safety of antithrombotic drugs used in patients with both atrial fibrillation (AF) and non-end-stage chronic kidney disease (NECKD).

Methods: A search was performed for studies on major bleeding outcomes in patients with concurrent AF and NECKD using Medline and Cochrane databases on 19th February, 2015. Fixed- or random-effects meta-analysis was adopted for evaluating pooled effect sizes according to whether heterogeneity existed.

Differences in Quality of Life Between Atrial Fibrillation Patients with Low Stroke Risk Treated With and Without Catheter Ablation.

Background: Impacts of a single radiofrequency ablation (RFA) on quality of life (QoL) were not well investigated in atrial fibrillation (AF) patients with low stroke risk.

Methods And Results: Nine hundred AF patients with low CHADS2 score (ie, CHADS2 ≤1) who completed both a baseline and 6-month Atrial Fibrillation Effect on QualiTy-of-life (AFEQT) questionnaire were selected from The Chinese Atrial Fibrillation Registry between 2011 and 2013. A final cohort of 222 patients was constructed after a propensity score matching with 74 in the RFA group and 148 in the non-RFA group.

Every patient with atrial fibrillation has his (her) own optimal heart rate.

Heart rate control is an important part of atrial fibrillation (AF) treatment and the recommendation for the target rate has become lenient in the recent guideline. Since heart rhythm of AF patients is irregularly irregular with great rate variation, the number of effective ventricular contractions may be different within a given time period among patients with similar heart rates and it may further lead to different levels of cardiac output. Therefore, we propose that every AF patient has his (her) own optimal heart rate, or to say that, the target for rate control in each AF patient should be individualized.
