Age and sex effects on the association between body composition and bone mineral density in healthy Chinese men and women.

Objective: Many studies have examined the relationships between body composition and bone mineral density (BMD), but little attention has been given to how these relationships vary by age and sex. The aim of this study was to investigate the distributions of lean mass (LM), fat mass (FM), and BMD and the correlation between body composition and BMD in Chinese men and women of different ages.

Methods: In total, the body compositions of 1,475 men and 1,534 women aged 20 to 96 years were analyzed.

Increased plasma acylation-stimulating protein in pediatric proteinuric renal disease.

Hyperlipidemia has been well recognized as a striking feature of nephrotic syndrome and other renal diseases. However, the underlying pathophysiological mechanisms still have not yet been elucidated. In this study, we evaluated acylation-stimulating protein (ASP) and complement component 3 (C3) in children (n=48) with various forms of proteinuric renal disease [nephrotic syndrome, acute poststreptococcal infection glomerulonephritis (APSGN), and lupus nephritis (LN)] in comparison with age- and gender-matched controls (n=279).
