A study on the effect of IL-6 gene polymorphism on the prognosis of non-small-cell lung cancer.

Background: Lung cancer is one of the most commonly diagnosed clinical diseases. IL-6 is a multifunctional cytokine that is related to chemotactic factors and tumor biological regulation. -174G/C polymorphism in the promoter region of the IL-6 gene single-nucleotide polymorphism is the -174 position change from G to C.

Effectiveness and safety of macrolides in bronchiectasis patients: a meta-analysis and systematic review.

Purpose: Macrolides has been studied as a potential therapeutic anti-inflammatory agent for bronchiectasis patients, which has used as an immunoregulation agent. However, the efficacy and safety results of macrolides across available randomized controlled trials (RCTs) are controversial. The aim of this systematic review is to evaluate the efficacy and safety of macrolides in bronchiectasis.

[Mechanism of impaired attention network in patients with stable chronic obstructive pulmonary disease].

Objective: To explore the influences of stable chronic obstructive pulmonary disease (COPD) on attention functions.

Methods: The research objects came from the Hospital Affiliated to Anhui Medical University from February to September in 2011. Attention network test (ANT) was employed to compare stable COPD patients (n = 38) with healthy controls (n = 36) in the efficiencies of anatomically defined attentional networks: alertness, orientation and executive attention.
