A novel nomogram for predicting postoperative pneumonia risk in patients with localized bronchiectasis.

Background: Pneumonia is one of the most common complications after lung resection. However, there are currently no reports of postoperative pneumonia in patients with bronchiectasis.

Objectives: Our study aims to construct a new nomogram to predict the risk of postoperative pneumonia in patients with localized bronchiectasis.

A multiplexed electrochemical quantitative polymerase chain reaction platform for single-base mutation analysis.

Detection of single-based mutation (SbM), which is of ultra-low abundance against wild-type alleles, are typically constrained by the level of multiplexing, sensitivity for single-base resolution and quantification accuracy. In this work, an electrochemical quantitative polymerase chain reaction (E-PCR) platform was developed for multiplexed and quantitative SbM analysis in limited and precious samples with single-nucleotide discrimination. A locked nucleic acid (LNA)-mediated multiplexed PCR system in a single, closed tube setup was firstly constructed to selectively amplify the SbM genes while suppressing the wild-type alleles.

A novel EZH2/NXPH4/CDKN2A axis is involved in regulating the proliferation and migration of non-small cell lung cancer cells.

NXPH4 is discovered to be a neuropeptide-like glycoprotein, belonging to the Neurexophilins (Nxphs) family. NXPH4 shares a similar domain structure with NXPH1, which, however, is poorly understood in terms of its function. Bioinformatics analysis and experimental verification in this study confirmed the abnormal high expression of NXPH4 in non-small cell lung cancer (NSCLC) tissues and cells.
