[Diagnostic value of ischemia-modified albumin in patients with acute coronary syndrome].

Objective: To investigate the diagnostic value of ischemia-modified albumin (IMA) for patients with acute coronary syndrome (ACS).

Methods: We detected the IMA levels by albumin cobalt-binding (ACB) test and observed its dynamic changes in 492 patients with ACS, 74 patients with high blood pressure, 78 patients with viral myocarditis (VMC), 395 patients with acute chest pain (133 patients with acute ACS and 262 follow-up patients due to chest pain), 68 patients underwent percutaneous coronary intervention (PCI) and 830 healthy controls. Cardiac troponin I (cTnI) levels were assayed and electrocardiogram (ECG) recorded in patients with ACS.

[Collagen type I and interleukin-1 beta gene expression in human atria during atrial fibrillation].

Objective: To determine whether gene expression of collagen type I and interleukin-1 beta (IL-1beta) is altered in patients with atrial fibrillation (AF).

Methods: Right atrial tissue samples were taken from 75 patients with rheumatic heart disease who underwent heart valve replacement surgery. 34 patients had no history of AF, 11 patients had paroxysmal AF and 30 patients had persistent AF.

[Effects of tetramethylpyrazine on fibrosis of atrial tissue and atrial fibrillation in a canine model of congestive heart failure induced by ventricular tachypacing].

Objective: To explore the effects of tetramethylpyrazine (TMP) on fibrosis of atrial tissue and atrial fibrillation in a canine model of congestive heart failure (CHF) induced by ventricular tachypacing.

Methods: Twenty-one healthy mongrel dogs were randomly divided into three groups, which were normal control group, untreated group and TMP-treated group. Atrial fibrillation (AF) was induced by burst of atrial pacing, after the canine model of CHF was established.
