[Association of fibrinogen B beta-chain gene polymorphism with factors affecting obesity].

Objective: To study the association of fibrinogen(Fg) B beta -854G/A, -455G/A, -249C/T, -148C/T, 448G/A and Bcl-1G/A gene polymorphisms with factors affecting obesity, and the fibrinogen function such as plasma fibrinogen concentration and molecular reactivity.

Methods: One thousand and three hundred ninety-one subjects from Kailuan corporation were enrolled by medical examination and questionnaire survey, and were divided into normal weight, overweight and obese groups based on body mass index (BMI). Blood biochemistry, fibrinogen concentration, fibrin monomer polymerized velocity (FMPV), and FMPV/A(max) were measured.

Relational analysis among fibrinogenic Bβ-chain gene polymorphisms and its functional expression and obesity.

Recently, there have been a few studies showing the association between obesity and fibrinogen (Fg) gene polymorphisms, but the reasons still do not clear completely. In this research, we studied the relationship among overweight, obesity and -854G/A, -455G/A, -249C/T, -148C/T, 448G/A, Bcl-1G/A gene polymorphisms of Fg β-chain and its functional expression such as plasma Fg concentration and molecule conglomerate function. 1391 subjects of retired aged employees from Kailuan Group were enrolled with medical examination and questionnaire survey, and which were divided into normal weight group (597 cases), overweight group (609 cases), obese group (185 cases) based on body mass index (BMI).
