Impacts of anti-inflammatory phosphodiesterase inhibitors on a murine model of chronic pulmonary inflammation.

Chronic obstructive pulmonary disease (COPD) often tends to respond poorly to glucocorticoid (GC) therapy. Reduced Histone deacetylase-2 (HDAC-2) activity is an important mechanism behind this GC insensitivity. In this study, we investigated the effects of three phosphodiesterase inhibitors (PDEIs), with an anti-inflammatory propensity, on cigarette smoke (CS)-induced pulmonary inflammation and HDAC-2 activity.

Effect of neutrophil CD64 for diagnosing sepsis in emergency department.

Background: The aim of this study is to investigate the diagnostic and prognostic value of neutrophil CD64 (nCD64) as a novel biomarker in sepsis patients.

Methods: One hundred fifty-one adult patients diagnosed with sepsis and 20 age-matched healthy controls were enrolled in the study. Patients with sepsis were further subdivided into a sepsis group and a septic shock group.

Efficacy of cytokine-induced killer cell-based immunotherapy for hepatocellular carcinoma.

In attempts to delay tumor progression after surgery or minimally invasive local treatments, multidisciplinary strategies have been broadly studied in patients with hepatocellular carcinoma (HCC). The objective of this present study was to evaluate the efficacy of autologous transplantations of cytokine-induced killer (CIK) cells as an adjuvant therapy for patients with HCC. A total of 264 patients with HCC were enrolled in this retrospective study.

MicroRNA‑192 acts as a tumor suppressor in colon cancer and simvastatin activates miR‑192 to inhibit cancer cell growth.

Colon cancer is one of the most common malignant tumors worldwide. Understanding the underlying molecular mechanisms is crucial for the development of therapeutic strategies for the treatment of patients with colon cancer. In the present study, a novel tumor suppressive microRNA, miR‑192, was demonstrated to be markedly downregulated in colon cancer cells compared with normal colon cells.

Fluorescence Resonance Energy Transfer-based Biosensor Composed of Nitrogen-doped Carbon Dots and Gold Nanoparticles for the Highly Sensitive Detection of Organophosphorus Pesticides.

The present article reports a novel biosensor for organophosphorus pesticides based on fluorescence resonance energy transfer (FRET) between nitrogen-doped carbon dots (NC-dots) and gold nanoparticles (AuNPs). The effective NC-dots/AuNPs assembly through the Au-N interaction results in good fluorescence quenching. Active acetylcholinesterase (AChE) catalyzes the hydrolysis of acetylthiocholine into -SH containing thiocholine to replace the NC-dots and trigger the aggregation of AuNPs.

[Role of BCG-depleted immunodominant antigens derived from M. tuberculosis in serological test for tuberculosis].

Objective: To explore the roles of BCG-depleted immunodominant antigens derived from M. tuberculosis in serological tests for tuberculosis (TB).

Methods: Four different combinations of current mainstream antigens used for serological diagnosis of TB were selected: Reagent A [Mycobacterium TB immunoglobulin G (IgG) antibody assay kit]; Reagent B (Mycobacterium TB detection kit); Reagent C (M.
