The 100 most cited articles in ectopic pregnancy: a bibliometric analysis.

Ectopic pregnancy (EP) remains a major gynecological emergency and is a cause of morbidity or even mortality in women. As a consequence, top citation analysis of EP research in database of the Science Citation Index Expanded is needed to assess the publication trends of leading countries/territories and institutes as well as the research hotspots of EP. A total of 4881 articles relevant to EP were retrieved in the database of the Science Citation Index Expanded from 1965 to present, in which the 100 top-cited articles were selected for further analysis.

Serum salusin-β levels are associated with the presence and severity of coronary artery disease.

Objectives: We sought to assess whether serum salusin-β levels are correlated with the presence and severity of coronary artery disease (CAD).

Methods: We measured serum salusin-β levels in 278 consecutive patients undergoing coronary angiography (CAG) for the evaluation of CAD and in 126 healthy controls. Serum salusin-β levels were measured by enzyme-linked immunosorbent assay.

Serum S100A12 concentrations are correlated with angiographic coronary lesion complexity in patients with coronary artery disease.

The neutrophil activation marker S100A12 is an important pro-inflammatory cytokine and a potential biomarker for a range of inflammatory diseases. This study aims to investigate whether serum S100A12 concentrations are associated with angiographic coronary lesion complexity in patients with coronary artery disease (CAD). We enrolled 240 CAD and 68 healthy controls.

[Association of ABCG2 gene C421A polymorphism and susceptibility of primary gout in Han Chinese males].

Objective: To assess the association between a C421A single nucleotide polymorphism (SNP) in exon 5 of ATP-binding cassette, sub-family G (WHITE), member 2 (ABCG2) gene and susceptibility of primary gout in Han Chinese males.

Methods: For 200 male patients with primary gout and 235 controls, the genotype of C421A locus was analyzed by PCR and direct sequencing. Blood glucose, uric acid, total cholesterol, triglycerides, creatinine and urea nitrogen was measured by an automatic biochemical analyzer.
