Vascular calcification occurs in more than half of chronic renal failure patients, which mainly appears in the large and medium size arteries [3, 4]. It seems that vas¬cular calcification is caused by dynamic imbal-ance of intravascular calcium and phosphorus. However, more and more studies pointed out that vascular calcification were related with local cell's function and biological characteris¬tics.~The aim of this study is to assess the effect of supplementation of vitamin K2 (menaquinone, MK-7) and cholecalciferol (inactive vitamin D) on circulating levels of calcification regulators and to assess their safety in pediatric patients on regular hemodialysis patients.
