A predictive model to explore risk factors for severe COVID-19.

With the rapid spread of the novel coronavirus (COVID-19), a sustained global pandemic has emerged. Globally, the cumulative death toll is in the millions. The rising number of COVID-19 infections and deaths has severely impacted the lives of people worldwide, healthcare systems, and economic development.

Biomarker of severity in hospitalised patients with COVID-19: a retrospective study.

Background: The novel COVID-19 was rapidly spreading and was highly contagious. COVID-19 caused over 6 million deaths worldwide, with high mortality rates, particularly in severe cases.

Objective: This study aimed to investigate whether serum albumin-neutrophil count to lymphocyte count ratio (NLR) score (ANS) could be used as a prognostic indicator of COVID-19 severity.

Application of Monocyte-to-Albumin Ratio and Neutrophil Percentage-to-Hemoglobin Ratio on Distinguishing Non-Small Cell Lung Cancer Patients from Healthy Subjects.

Objective: This study aims at assessing the potential benefits of observation of monocyte-to-albumin ratio (MAR) and neutrophil percentage-to-hemoglobin ratio (NPHR) in the detection of non-small cell lung cancer (NSCLC).

Methods: This study retrospectively involved 195 NSCLC patients and 204 healthy volunteers. The correlations between the clinicopathological characteristics of NSCLC and the two ratios including MAR and NPHR were assessed.

Additional diagnostic value of the monocyte to red blood cell count ratio and the product of lymphocyte count and albumin concentration in lung cancer management.

The present study aimed to evaluate the potential of the monocyte to red blood cell count ratio (MRR), the neutrophil to red blood cell count ratio (NRR), the lymphocyte to red blood cell count ratio (LRR) and the product of lymphocyte count and albumin concentration (LA) for the diagnosis of lung cancer. The cases of 216 patients with newly diagnosed lung cancer and 184 healthy volunteers were retrospectively analysed. The MRR and NRR were found to be higher in patients with lung cancer compared with those in healthy controls, while the LRR and LA were lower.

miR‑625‑5p suppresses inflammatory responses by targeting AKT2 in human bronchial epithelial cells.

Asthma is a common chronic inflammatory airway disease; however, whether microRNAs (miRs) could be used in the treatment of asthma remains unclear. The aim of the present study was to investigate the role of miR‑625‑5p in the inflammatory response of human bronchial epithelial cells (HBECs). Inflammation in the HBEC line, 16HBEC, was induced using different concentrations of lipopolysaccharide (LPS), which demonstrated that 1 µg/ml LPS was an appropriate concentration for further experiments.

Associations of Toll-like receptor 7 and 8 Polymorphisms with Asthma and Asthma-related Phenotypes in a Chinese Han Population.

Toll-like receptor (TLR) 7 and 8 mediate anti-virus immunity and are of particular relevance to asthma. However, very little information about genetic association on TLR7/8 and asthma are available. This study aimed to evaluate the effects of polymorphisms in TLR7 and 8 on asthma risk and asthma-related phenotypes in a Chinese Han population.

High-sensitivity C-reactive protein: a predicative marker in severe asthma.

Background And Objective: Serum levels of high-sensitivity CRP (hs-CRP) are associated with asthma but the relationship between higher levels of hs-CRP and the degree of asthma severity remains unclear. This study investigated whether hs-CRP is associated with asthma severity as well as with other clinical indices of asthma activity (pulmonary function, total serum IgE, and peripheral blood eosinophil counts).

Methods: Levels of hs-CRP and clinical indices of asthma were determined among 177 control subjects and 281 asthmatic patients (84 intermittent, 30 mild, 63 moderate and 104 severe).

Increased RhoGDI2 and peroxiredoxin 5 levels in asthmatic murine model of beta2-adrenoceptor desensitization: a proteomics approach.

Background: Beta(2)-adrenoceptor (beta(2)AR) desensitization is a common problem in clinical practice. beta(2)AR desensitization proceeds by at least such three mechanisms as heterologous desensitization, homologous desensitization and a kind of agonist-induced rapid phosphorylation by a variety of serine/threonine kinases. It is not clear whether there are other mechanisms.

Expression of surface markers on peripheral CD4+CD25high T cells in patients with atopic asthma: role of inhaled corticosteroid.

Background: CD4(+)CD25(+) regulatory T cells (Tregs) mediate immune suppression through cell-cell contact with surface molecules, particularly cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), glucocorticoid-induced tumor necrosis factor receptor family-related protein (GITR), and transforming growth factor beta (TGF-beta), but little is known about the exact role of Tregs in the pathogenesis of asthma. This study sought to characterize the expression of surface markers on peripheral blood mononuclear cells-derived Tregs in patients with atopic asthma and healthy subjects, and to investigate the effect of inhaled corticosteroid on them.

Methods: The expression of surface molecules on CD4(+)CD25(high) Tregs was detected by flow cytometry.
