Red cell size factor is a sensitive index in the early diagnosis of nondigestive tract cancer-related anemia: An observational study.

Cancer-related anemia (CRA) is a common comorbidity in cancer patients, and it can lead to a worse prognosis. The aim of this cross-sectional study is to investigate the clinical value of the red cell size factor (Rsf) in the early diagnosis of nondigestive tract CRA. A total of 231 patients with nondigestive tract solid cancer were included, and they were divided into anemic and nonanemic subjects according to the hemoglobin (Hb) levels.

JMJD2A mediates transcriptional activation of SFRP4 and regulates oxidative stress and mitochondrial dysfunction in heart failure.

The importance of mitochondrial dysfunction and oxidative stress has been indicated in the progression of heart failure (HF). The molecular mechanisms, however, remain to be fully elucidated. This study aimed to explore the role and underlying mechanism of secreted frizzled-related protein 4 (SFRP4) in these two events in HF.

Glycolytic regulatory enzyme PFKFB3 as a prognostic and tumor microenvironment biomarker in human cancers.

The 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFK-2/FBPase-2, PFKFB3) is a glycolysis regulatory enzyme and plays a key role in oncogenesis of several cancers. However, the systematic study of crosstalk between PFKFB3 and Tumor microenvironment (TME) in pan-cancer has less been examined. In this study, we conducted a comprehensive analysis of the relationship between expression, patient prognostic, Tumor mutational burden (TMB), Microsatellite instability (MSI), DNA mismatch repair (MMR), and especially TME, including immune infiltration, immune regulator, and immune checkpoint, across 33 types of tumors using datasets of The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO).

HDAC1 Promotes Myocardial Fibrosis in Diabetic Cardiomyopathy by Inhibiting BMP-7 Transcription Through Histone Deacetylation.

Objective: Diabetic cardiomyopathy (DCM) constitutes a primary cause of mortality in diabetic patients. Histone deacetylase (HDAC) inhibition can alleviate diabetes-associated myocardial injury. This study investigated the mechanism of HDAC1 on myocardial fibrosis (MF) in DCM.

Evaluation of Cardiac Space-Occupying Lesions by Myocardial Contrast Echocardiography and Transesophageal Echocardiography.

Heart space-occupying lesions are a disease that occurs frequently in clinical setting, and therefore, it is important to diagnose and treat this type of pathologies properly. Angiographic echocardiography and transesophageal sonogram are widely used for clinical diagnosis. Their application provides a guarantee for the diagnosis of cardiac space-occupying lesions.

Overexpression of miR-1298 attenuates myocardial ischemia-reperfusion injury by targeting PP2A.

Previous studies reported that microRNA-1298 was abnormally expressed in the myocardium of rat hearts after hypoxia/normoxia injury. This study aims to investigate the function and specific mechanism of miR-1298 in myocardial ischemia/reperfusion (IR) injury. Neonatal rat cardiomyocytes (NRCMs) were isolated from neonatal rat hearts and subjected to oxygen/glucose deprivation/reperfusion (OGD/R) to induce I/R injury.

LncRNA H19 regulates smooth muscle cell functions and participates in the development of aortic dissection through sponging miR-193b-3p.

Background: Multiple studies showed that long-chain noncoding RNA H19 (LncRNA H19) is high-expressed in human and mouse abdominal aortic aneurysms (AAAs). We speculated that it plays an important role in arterial disease, and therefore studied the role and mechanism of H19 in aortic dissection (AD).

Methods: The expressions of related genes in human aortic smooth muscle cells (HASMCs) induced by platelet-derived growth factor BB (PDGF-BB) or in the aortic tissue of AD patients/mice were identified by Western blot and quantitative real-time polymerase chain reaction.

Comparison of curative effect between different anticoagulation regimens in continuous renal replacement therapy after cardiac valve replacement.

Objectives: To compare the clinical effect of low molecular weight heparin (LMWH) and regional citrate anticoagulation (RCA) in continuous renal replacement therapy (CRRT) after heart valve replacement.

Methods: Retrospective analysis of clinical data from 60 patients undergoing continuous renal replacement therapy after heart valve replacement in Peking University Shenzhen Hospital from January 2015 to July 2019, including 35 males and 25 females, aged (58.83 ±16.

[Purification and characterization of two PR-10 protein isoforms from the crude drug of Angelica sinensis].

Two proteins of similar molecular weight (named as ASPR-C-1 and ASPR-C-2) from the crude drug of Angelica sinensis were purified and characterized by 80% ammonium sulfate precipitation, Sephadex G-50 gel filtration chromatography, and DEAE-Sepharose anion exchange chromatography. The molecular weight of ASPR-C-1 and ASPR-C-2 on SDS-PAGE was 17.33 kDa and 17.

Mesoporous Silica Nanoparticles Rescue HO-induced Inhibition of Cardiac Differentiation.

The anti-oxidative property of mesoporous silica nanoparticles (MSNs) has been proposed previously, which prompted us to investigate the potential protective effect of MSNs on human embryonic stem cells (hESCs) against oxidative stress. To this purpose, the cell viability was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay. Apoptosis was analyzed by Annexin V/propidium iodide double-staining method.

Purification and characterization of two pathogenesis-related class 10 protein isoforms with ribonuclease activity from the fresh Angelica sinensis roots.

In this study, two pathogenesis-related (PR) class 10 protein isoforms, ASPR-1 and ASPR-2, were purified from fresh roots of the Chinese medicinal plant Angelica sinensis (A. sinensis) using 80% ammonium sulfate precipitation, Sephadex G50 gel filtration chromatography, and DEAE-Sepharose ion-exchange chromatography. The molecular masses of ASPR-1 and ASPR-2 were estimated to be 16.

Role of VR1 in the differentiation of bone marrow-derived mesenchymal stem cells into cardiomyocytes associated with Wnt/β-catenin signaling.

Aim: Accumulating evidence showed that transient receptor potential channels play an important role in the regulation of cardiomyocyte differentiation. The vanilloid receptor 1 (VR1) is a member of the transient receptor channel super family and is expressed in cardiomyocytes. However, its function in cardiomyocytes remains unclear.
