The aim of the present study was to observe the effect of sacubitril valsartan on cardiac function and vascular endothelial function in patients with chronic heart failure with reduced ejection fraction (HFrEF).<br /><br /> A total of 80 patients with HFrEF were randomly divided into an observation group and a control group, with 40 patients in each group. Sacubitril valsartan was added to the conventional treatment in the observation group, and perindopril was added to the conventional treatment in the control group. Both groups were treated continuously for 12 weeks. The left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), flow-mediated vasodilatory function (FMD) of the brachial artery, and levels of plasma Ang II, endothelin 1 (ET-1), and calcitonin gene-related peptide (CGRP), together with the serum nitric oxide (NO) and NO synthase (NOS) were compared before and after treatment in the groups.<br /><br /> Before the treatment, the levels of LVEF, LVEDD, FMD, Ang II, ET-1, CGRP, NO, and NOS in the observation group were not significantly different from those in the control group (P &gt; 0.05). However, the levels of LVEF, FMD, CGRP, NO, and NOS in both groups were significantly higher after the treatment than those before the treatment (P &lt; 0.05) and significantly higher in the observation group than those in the control group. The difference was statistically significant (P &lt; 0.05). Meanwhile, the levels of LVEDD, Ang II, and ET-1 in both groups decreased significantly after the treatment (P &lt; 0.05) and were significantly lower in the observation group than those in the control group. The difference was statistically significant (P &lt; 0.05).<br /><br /> Sacubitril valsartan might improve endothelial function while increasing cardiac function in HFrEF patients.<br /><br />Sacubitril valsartan might improve endothelial function while increasing cardiac function in HFrEF patients.<br /><br /> The aim of the present study was to evaluate the effectiveness and safety of nicorandil in improving the area of myocardial infarction in patients with acute myocardial infarction (AMI).<br /><br /> One hundred and twenty patients with acute ST-segment elevation myocardial infarction (STEMI) admitted to our hospital between December 1, 2018 and December 31, 2019 were selected and randomly allocated to the experimental group (group A, n = 60) and the control group (group B, n = 60). In the experimental group, an infusion of nicorandil was given intravenously before the first balloon dilation or 1 minute before the stent placement, and with the completion of the infusion, nicorandil maintenance infusion was given. In the control group, only balloon dilation and stent placement were undertaken.<br /><br /> The postoperative peak levels of myoglobin, creatine kinase isoform and hypersensitive troponin T were significantly lower in group A than in group B (p &lt; 0.05). Moreover, the left ventricular ejection fraction (LVEF) on thel in patients with STEMI during the perioperative percutaneous coronary intervention (PCI) period was effective in reducing the area of myocardial infarction and myocardial injury without increasing the incidence of malignant arrhythmias, hypotension, or composite cardiovascular events during the drug administration period.<br /><br /> Calcium, vitamin D and insulin resistance are linked to osteoporosis and cardiovascular disease in menopause.<br /><br /> Determine if hemorheological parameters related to blood viscosity in microcirculation are linked to calcium metabolism and insulin resistance in menopause.<br /><br /> 25-Hydroxyvitamin D (25(OH)D)), 1, 25-dihydroxyvitamin D3 (1, 25(OH)2D), parathyroid hormone, ionized calcium, glucose, insulin and hemoglobin A1c were measured in blood from 43 volunteers. Red blood cells (RBC) aggregation, RBC deformability and whole blood viscosity were also performed.<br /><br /> 25(OH)D showed a positive correlation with RBC deformability 0.60 Pa. Subjects with 25(OH)D≤29.00 ng/mL had lower RBC deformability 0.60 Pa, and higher RBC aggregation and higher HOMA-IR. Ionized calcium showed a negative correlation with RBC aggregation. Subjects with ionized calcium ≤1.24 mmol/L showed higher RBC aggregation. There was a positive correlation between HOMA-IR and RBC aggregation and HOMA-IR showed a negative correlation with RBC deformability 0.30 Pa. Subjects with HOMA-IR &lt;1.80 showed lower RBC aggregation and higher RBC deformability at 0.30 Pa, 0.60 Pa, 1.20 Pa, 3.0 Pa and 6.0 Pa.<br /><br /> Low 25(OH)D, low ionized calcium and high HOMA-IR are related to impaired hemorheology in menopause. RBC aggregation and deformability can be used as biomarkers of calcium metabolism and insulin resistance in menopause.<br /><br />Low 25(OH)D, low ionized calcium and high HOMA-IR are related to impaired hemorheology in menopause.

Moreover, human CRC epithelial cell lines, including HT29, SW480, SW620 and LoVo, were purchased in advance, and their activity was estimated after transfection of si-XIST or miR-137 mimic. Furthermore, 5-FU/cisplatin-resistance of CRC cells was determined through MTT assay, and glycolytic potential of CRC cells was appraised based on oxygen consumption rate (OCR) and extracellular acidification rate (ECAR).<br /><br /> Highly-expressed XIST were predictive of severe symptoms and unfavorable 3-year survival of CRC patients (P&lt; 0.05). Besides, silencing of XIST not only diminished proliferative, migratory and invasive power of CRC cells (P&lt; 0.05), but also enhanced sensitivity of CRC cells responding to 5-FU/cisplatin (P&lt; 0.05). Glycolytic potency of CRC cells was also undermined by si-XIST, with decreased maximal respiration and maximal glycolytic capacity in the si-XIST group as relative to NC group (P&lt; 0.05).

Ultimately, ratio of PKM2 mRNA and PKM1 mRNA, despite being up-regulated by pcDNA3.1-XIST, was markedly lowered when miR-137 mimic was co-transfected (P&lt; 0.05).<br /><br /> LncRNA XIST/miR-137 axis reinforced glycolysis and chemo-tolerance of CRC by elevating PKM2/PKM1 ratio, providing an alternative to boost chemo-therapeutic efficacy of CRC patients.<br /><br />LncRNA XIST/miR-137 axis reinforced glycolysis and chemo-tolerance of CRC by elevating PKM2/PKM1 ratio, providing an alternative to boost chemo-therapeutic efficacy of CRC patients.
