Ethylene/ethane divorce in the secure hydrogen-bonded natural and organic composition by way of a gating procedure.
MiR-495 expression was remarkably increased in H9c2 cells treated with hypoxia. Inhibiting miR-495 expression markedly alleviated the hypoxia-induced injury in H9c2 cells, while silencing NFIB aggravated the hypoxia-induced damage. In addition, NFIB was confirmed to be the target of miR-495.

MiR-495 expression was increased in hypoxia-treated H9c2 cells. Silencing miR-495 could significantly inhibit hypoxia-induced apoptosis of H9c2 cells by targeting NFIB.

The incidence of acute myocardial infarction (AMI) has increased significantly in recent years, seriously threatening human life and health. This paper focused on the role of microRNA-802-5p (miR-802-5p) in myocardial infarction (MI) and its underlying mechanisms.

Quantitative Real-Time Polymerase Chain Reaction (RT-PCR) was employed to detect miR-802-5p expression. Western blot was performed to detect protein expression. Flow cytometry and terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) staining were performed to observe myocardial apoptosis. Hematoxylin-eosin (HE) staining was used to observe the morphology of myocardial tissue. The cardiac function of rats was detected using echocardiography.

The expression of miR-802-5p was increased in hypoxic-treated H9c2 cells and infarcted myocardium in MI rats. Hypoxia treatment reduced the viability of cardiomyocytes and increased the level of lactate dehydrogenase (LDH) in the cell supernatant. Hypoxia treatment increased Bainjury and improving cardiac function of MI rats.
Multiple pathophysiological conditions are associated with disturbance of myocardial osmotic equilibrium, exerting detrimental effects on cardiac performance. Cardiac myocytes may encounter hyperosmotic stress during hyperglycemia, ischemia/reperfusion injury, myocardial infarction, diabetes mellitus, severe dehydration, hypoxia or heat stress. Aquaporins (AQPs) constitute transmembrane channels that facilitate water transport in response to osmotic gradients. Therefore, the present study aimed at probing into AQPs mode of response and potential role as effector molecules and sensors, under hyperosmotic stress.

H9c2 cardiac myoblasts were left untreated (control) or were exposed to 0.5 M sorbitol so as to induce hyperosmotic stress conditions. After the experimental treatments, MTT assay was performed to assess cell viability. Endogenous mRNA levels of AQP1 and AQP7 were assessed by ratiometric RT-PCR. Their subcellular localization pattern was revealed by immunofluorescence microscopy. Protein levels of s sensor and response factor, exerts a beneficial effect against the sorbitol-induced apoptosis, potentially favoring preservation of cardiac function.
Coronary artery disease (CAD) is the main cause of mortality worldwide. How stable coronary artery disease (SCAD) progresses to acute myocardial infarction (AMI) is not known. This study was aimed to explore the differentially expressed genes (DEGs) and pathways involved in the progression of SCAD to AMI.

Publicly available gene-expression profiles (GSE71226, GSE97320, GSE66360) were downloaded from the Gene Expression Omnibus (GEO) database and integrated to identify DEGs. The GSE59867 dataset was further used to verify the result of screened DEGs. Functional-enrichment analyses, protein-protein interaction network, microRNA-transcription factor (TF)-mRNA regulatory network, and drug-gene network were visualized.

Sixty common DEGs (CDEGs) were screened between the SCAD-Control group and AMI-Control group in the integrated dataset. Four upregulated DEGs were selected from GSE59867. Twenty hub genes were discovered, and three significant modules were constructed in the PPI network. The intersection of fu-α2 glycoprotein-1 (LRG1), mothers Against Decapentaplegic Homolog 4 (SMAD4) and miRNA-149-5p, miRNA-6778-3p, and miRNA-520a-3p. Inflammation and the immune response had important roles in the progression from SCAD to AMI.
This study aims to evaluate the changes in left ventricular diastolic function after coronary artery bypass grafting through tissue Doppler imaging (TDI) and N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration and the correlation between the two.

A total of 133 patients who underwent coronary artery bypass grafting between January 2016 and December 2018 were included in this study. Echocardiography and NT-proBNP concentration were reviewed pre-operation, 1 month post-operation, and 3-6 months post-operation. The transmitral peak flow velocity (E) of the mitral valve was measured at each of the three-time points using spectral Doppler imaging. The mitral annulus displacement (Ea peak and Aa peak) was then measured at each of the time points using TDI, and the E/Ea ratio was calculated. Subsequently, the correlation of the E value, Ea value, and E/Ea ratio with NT-proBNP concentration was statistically analyzed.

The data obtained at the three-time points were compared with the respective concentrations of NT-proBNP. Multiple linear regression analysis revealed a correlation between NT-proBNP concentration and E value, Ea value, and E/Ea ratio.

Left ventricular diastolic function gradually recovered at 1 month and 3-6 months after coronary artery bypass grafting. There was a correlation between TDI-related values and NT-proBNP concentration.

Changes of microRNAs (miRNAs) may contribute to the pathogenesis and progression of postoperative atrial fibrillation (POAF) in patients undergoing cardiac valve surgery. This study aimed to measure the expression levels of miRNAs in peripheral blood, as well as their target mRNAs, in POAF patients and normal controls (non-POAF), and to evaluate the potential of miRNAs as promising biomarkers to predict POAF.

The expression of miRNAs in peripheral blood, including miR-27b, miR-133a, miR-328, miR-499 and their target mRNAs, was analyzed in 109 POAF patients and 96 non-POAF patients via quantitative real-time polymerase chain reaction (RT-PCR). We compared differences between the two groups and also analyzed the treat reaction to amiodarone.

All miRNAs in POAF patients were significantly highly expressed. Compared to non-POAF, the expression of miR-27b, miR-133a, miR-328, miR-499 increased in both groups of POAF patients, and miR-499 was the only upregulated miRNAs in the amiodarone - group versus amiodarn POAF patients compared to non-POAF patients. Further, the present results showed that miR-499 was significantly upregulated in amiodarone - patients, compared to non-POAF, and amiodarone + patients. This finding indicates that miR-499 may be a potential biomarker for predicting the occurrence of POAF after cardiac valve surgery and treat the reaction to amiodarone.
Although many previous meta-analyses of epidemiological studies have demonstrated a relationship between body mass index (BMI) and mortality, inconsistent findings among cardiovascular disease patients have been observed. Thus, we performed an umbrella review to understand the strength of evidence and validity of claimed associations between BMI and mortality in patients with cardiovascular diseases.

We comprehensively re-analyzed the data of meta-analyses of observational studies and randomized controlled trials on associations between BMI and mortality among patients with cardiovascular diseases. We also assessed the strength of evidence of the re-analyzed outcomes, which were determined from the criteria including statistical significance of the p-value of random-effects, as well as fixed-effects meta-analyses, small-study effects, between-study heterogeneity, and a 95% prediction interval.

We ran comprehensive re-analysis of the data from the 21 selected studies, which contained a total of 108 meta-analyses; 23 were graded as convincing evidence and 12 were suggestive, 42 were weak, and 23 were non-significant.

The importance of continuous monitoring of fasting blood sugar (FBS) levels of diabetic patients has been established.

An observational prospective study was conducted. Our analysis included 1,700,796 individuals from the nationwide South Korean National Health Insurance System cohort. FBS variability was measured by standard deviation (SD).

Kaplan-Meier curves demonstrated elevated disease probability in the higher FBS fluctuation group compared with the lower FBS fluctuation group. After adjusting for confounding variables, Cox proportional hazards analysis showed that the hazard ratios of 411 individuals in the highest quartile of SD variation of FBS were 1.77 (95% confidence interval 1.37-2.28, p<0.001) compared with the lowest quartile of SD variation of FBS. The impact of FBS fluctuation on the risk of cardiovascular diseases (CVDs), cerebrovascular diseases, CVD mortality and all-cause mortality in the highest quartiles of diabetic and non-diabetic individuals was statistically significant.

Visit-to-visit FBS variability has prognostic value for predicting micro- and macrovascular disease, cardiovascular mortality, and all-cause mortality.

We aimed to systematically review biological agents' efficacy and safety in patients with Takayasu arteritis (TAK).

A systematic literature search of 7 electronic databases, including MEDLINE (via PubMed), EMBASE, Elsevier ScienceDirect, EBSCO, Springer Link, Web of Science, and Cochrane Library on the efficacy of biological agents on patients with TAK was conducted. Only studies published in English and with a sample size >5 patients with TAK were included. Two reviewers independently selected studies, extracted data and assessed its methodological quality. Random effects meta-analyses of various effect measures were performed.

According to the title and abstract, 961 studies were identified and screened. Subsequently, 31 studies from 29 observational studies and 2 randomized-controlled trials (RCTs), which included a total of 517 patients with TAK that met the inclusion and exclusion criteria, were selected. Observational studies showed a high risk of bias. Pooled remission rates of biological agenagents was infection (6%, 95%CI 2%-10%). No deaths were reported.

Although the beneficial effects of biological agents are encouraging in enhancing disease remission, reducing the levels of acute phase inflammation markers and decreasing the treatment doses of GC in patients with TAK, there is still a risk of relapse. More refined studies with larger cohorts are necessary before drawing a definitive opinion.
