Effect of Kidney Yin/Yang Replenishment on Bone Metabolism in Patients With Renal Osteodystrophy

In this study patients with chronic renal insufficiency and secondary osteoporosis or bone loss will be evaluated with traditional Chinese medicine standard and allocated into kidney Yin deficiency and kidney Yang deficiency groups. In Yin deficiency group, patients will be divided into Zuogui granules treatment group and placebo group. In Yang deficiency group, patients will be divided into Yuogui granules treatment group and placebo group. All the patients will also accept basic treatment. After 3-month-treatment, we will detect blood urea nitrogen, creatinine, bone mineral density, bone metabolism markers including FGF23, 1,25(OH)2D3, Osteocalcin, PTH, BALP, serum and urinal Ca, P. We will also perform miRNA array. The data before treatment and after treatment will be compared. The data of treatment groups and placebo groups will also be compared.
