Essential blood molecular signature for progression of sepsis-induced acute lung injury: Integrated bioinformatic, single-cell RNA Seq and machine learning analysis.

In this study, we aimed to identify an essential blood molecular signature for chacterizing the progression of sepsis-induced acute lung injury using integrated bioinformatic and machine learning analysis. The results showed that a total of 88 functionally related ALI-associated hub genes in sepsis were identified by MCODE analysis and they were enriched in infection and inflammtory responses, lung and cardiovascular disease pathways. These hub genes stratified ALI-sepsis and sepsis and further stratified two subtypes of sepsis-ALI with differential ALI scores, hub gene expression patterns, and levels of immune cells.

Thinking Induced by Acute Kidney Injury of Diquat Poisoning: Cases Report.

Diquat poisoning is a fatal condition that is becoming increasingly common. The mortality risk of patients taking lethal doses of diquat is extremely high. It typically leads to rapid dysfunction of multiple organs, including the kidneys, heart, lungs, and brain.

Origin recognition complex subunit 6 (ORC6) is a key mediator of LPS-induced NFκB activation and the pro-inflammatory response.

Lipopolysaccharide (LPS)-activated pro-inflammatory responses play a critical role in sepsis, a life-threatening condition. This study investigates the role of origin recognition complex subunit 6 (ORC6) in LPS responses in macrophages and monocytes. Silencing ORC6 using targeted shRNA significantly reduced LPS-induced expression and production of IL-1β (interleukin-1 beta), TNF-α (tumor necrosis factor alpha), and IL-6 (interleukin-6) in THP-1 human macrophages, peripheral blood mononuclear cells (PBMCs), and bone marrow-derived macrophages (BMDMs).

Physicochemical Characterization and Pharmacological Evaluation of Novel Propofol Micelles with Low-Lipid and Low-Free Propofol.

We developed safe and stable mixed polymeric micelles with low lipids and free propofol for intravenous administration, to overcome the biological barrier of the reticuloendothelial system (RES), reduce pain upon injection, and complications of marketed propofol formulation. The propofol-mixed micelles were composed of distearoyl-phosphatidylethanolamine-methoxy-poly (ethylene glycol 2000) (DSPE mPEG2k) and Solutol HS 15 and were optimized using Box Behnken design (BBD). The optimized formulation was evaluated for globule size, zeta potential, loading content, encapsulation efficiency, pain on injection, histological evaluation, hemolysis test, in vivo anesthetic action, and pharmacokinetics, in comparison to the commercialized emulsion Diprivan.

PERFORM: Pulmonary embolism risk score for mortality in computed tomographic pulmonary angiography-confirmed patients.

Background: Current prognostic scores for pulmonary embolism (PE) were partly based on patients without PE confirmation via computed tomographic pulmonary angiography (CTPA), involving subjective parameters and complicated scoring methods. Therefore, we sought to develop an objective, accurate, and simple prognostic model in CTPA-confirmed patients to predict the risk of 30-day mortality.

Methods: We retrospectively evaluated 509 patients with objectively confirmed PE by CTPA from 2010 to 2017 in the Minhang Hospital, which is affiliated to Fudan University.

Glucocorticoids Regulate the Activation of Neutrophils and Inhibit the Formation of Pulmonary Embolism.

Background: There is a close relationship between neutrophil extracellular traps (NETs) and venous thromboembolism (VTE). The regulatory role and mechanism of glucocorticoids (GC) in the formation of NETs are unclear.

Objective: This study was conducted to assess the effect of GC on the formation of NETs.

Supramolecular Hunter Stationed on Red Blood Cells for Detoxification Based on Specific Molecular Recognition.

Efficient removal of deadly toxicants by blood purification remains predominant in poisoning treatment. Current strategies mainly rely on absorptive scavengers that normally have no selectivity to the adsorbates, which could result poor clinical outcomes to certain toxic species due to the passivity and inaccuracy of the detoxification procedure. Herein, a positive, accurate, and customized detoxification strategy was proposed.

Long noncoding RNA colorectal neoplasia differentially expressed alleviates sepsis-induced liver injury via regulating miR-126-5p.

In this study, we intended to determine the detailed function and mechanism of long noncoding RNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) in liver injury induced by sepsis. Cecal ligation and perforation (CLP) models were adopted to induce sepsis in vivo with rats, and hepatic epithelial cells L02 were treated with lipopolysaccharide (LPS) to mimic sepsis in vitro. Enzyme-linked immunosorbent assay was conducted to detect the levels of tumor necrosis factor (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), and interferon-γ (IFN-γ) in the serum of rats.

Down-regulation of LncRNA CRNDE aggravates kidney injury via increasing MiR-181a-5p in sepsis.

Long non-coding RNA (lncRNA) colorectal neoplasia differentially expressed (CRNDE) is reported to be linked to inflammation and cell apoptosis. However its role in sepsis induced kidney injury remains unclear. This study aims to explore the possible mechanism of CRNDE in kidney injury induced by sepsis.

LIN28B-AS1-IGF2BP1 association is required for LPS-induced NFκB activation and pro-inflammatory responses in human macrophages and monocytes.

Insulin-like growth factor 2 (IGF2) mRNA-binding protein 1 (IGF2BP1) mediates lipopolysaccharide (LPS)-induced NFκB activation and pro-inflammatory cytokines production in human macrophages. Recent studies have identified a novel IGF2BP1-binding LncRNA LIN28B-AS1. In the present study we show that LPS induced LIN28B-AS1-IGF2BP1 association in THP-1 macrophages, required for LPS-induced IGF2BP1-p65-p52 association and NFκB activation.

Bioinformatics-based study to detect chemical compounds that show potential as treatments for pulmonary thromboembolism.

The objectives of the present study comprised the recognition of major genes related to pulmonary thromboembolism (PTE) and the evaluation of their functional enrichment levels, in addition to the identification of small chemical molecules that may offer potential for use in PTE treatment. The RNA expression profiling of GSE84738 was obtained from the Gene Expression Omnibus database. Following data preprocessing, the differently expressed genes (DEGs) between the PTE group and the control group were identified using the Linear Models for Microarray package.

Disulfide-based PEGylated prodrugs: Reconversion kinetics, self-assembly and antitumor efficacy.

The prodrug strategy serves well in drug formulation and delivery. Two disulfide-based PEGylated prodrugs were developed and the drug reconversion upon different conditions were studied in detail. The reconversion-induced oversaturation phenomenon was firstly reported here.

Vaccine based on antibody-dependent cell-mediated cytotoxicity epitope on the H1N1 influenza virus increases mortality in vaccinated mice.

Antibody-dependent cell-mediated cytotoxicity bridges humoral immunity and cellular immunity. Thus vaccine candidates which can elicit both broadly neutralizing antibodies and potent antibody-dependent cell-mediated cytotoxicity (ADCC) are recommended. Previously, a panel of functional epitopes that can elicit ADCC effects is isolated and characterized on the H1N1 Influenza Virus.

CC-223 blocks mTORC1/C2 activation and inhibits human hepatocellular carcinoma cells in vitro and in vivo.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related human mortalities. Over-activation of mammalian target of rapamycin (mTOR) is important for HCC tumorigenesis and progression. The current study assessed the potential anti-HCC activity by a novel mTOR kinase inhibitor, CC-223.
