Development and validation of nomogram including high altitude as a risk factor for COPD: A cross-sectional study based on Gansu population.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a common and harmful disease that requires an effective tool to early screen high-risk individuals. Gansu has unique environments and customs, leading to the different prevalence and etiology of COPD from other regions. The association between altitude and COPD once attracted epidemiologists' attention.

Predictive value of LncRNA on coronary restenosis after percutaneous coronary intervention in patients with coronary heart disease: A protocol for systematic review and meta-analysis.

Background: Evidence shows that long-stranded non-coding RNA (LncRNA) can predict coronary artery restenosis in patients suffering from coronary heart disease after percutaneous coronary intervention, suggesting that LncRNA may become a promising biomarker for the diagnosis of coronary artery restenosis after percutaneous coronary intervention. However, its accuracy has not been systematically evaluated. Therefore, it is necessary to perform meta-analysis to certify the diagnostic value of LncRNA on coronary artery restenosis after percutaneous coronary intervention.

Associations Between Common Polymorphisms of and Susceptibility to ASCVD.

This meta-analysis was conducted to estimate associations between CDKN2B antisense () polymorphisms and susceptibility to atherosclerotic cardio-cerebral vascular diseases (ASCVD). A systematic literature research of PubMed, Medline, Web of Science, Embase, and CNKI was performed to identify eligible studies. Overall, 34 studies were included for meta-analyses.

WITHDRAWN: A meta-analysis on associations of CDKN2B-AS variants with atherosclerotic cardio-cerebral vascular diseases.

Association between α-adducin rs4961 polymorphism and hypertension: A meta-analysis based on 40 432 subjects.

Background: Recently, the role of α-adducin rs4961 polymorphism in hypertension (HTN) was intensively analyzed, but the results of these studies were inconsistent. Therefore, we performed this study to better assess the relationship between α-adducin rs4961 polymorphism and the likelihood of HTN.

Methods: Eligible studies were searched in PubMed, Medline, Embase, and Web of Science.

Changes in matrix metalloproteinase-9 levels during progression of atrial fibrillation.

Objectives: To observe levels of matrix metalloproteinase (MMP)-9 and evaluate their significance in various stages of idiopathic atrial fibrillation (AF).

Methods: Patients with idiopathic AF were recruited into this prospective study and classified into one of three groups according to stage of disease progression: paroxysmal AF; persistent AF; permanent AF. Healthy individuals were enrolled as control subjects.
