description To construct recombination eukaryote expression plasmid for human parathyroid hormone (PTH) gene, assay PTH expression and biological activity after transfection in vitro and evaluate gene therapy effect on hypoparathyroidism (HPT). (1) PTH gene was amplified from human embryonic parathyroid gland tissue, and plasmid pcDNA3.1-PTH-GFP (pcDPG) was constructed by TOPO recombination technique. Digestion, PCR and sequencing were used to identify the positive vectors. (2) pcDPG was transformed into 293 cells by Lipofectamine 2000(TM), fluorescent inverted microscope was used to observe GFP expression, and PTH gene expression was assayed by RT-PCR technique. (3) PTH protein in supernatant was purified and evaluated biological activity. (4) HPT rabbit models were developed and plasmid pcDPG was injected in skeletal muscles, respectively. Serum calcium, phosphonium and PTH were assayed and pathological changes observed. (1) The findings in digestion and PCR were accorded to anticipation and sequences in report were id
