Objective To investigate the gene therapy of hypoparathyroidism (HPT) with hemopoietic stem cell s(HSCs) integrated with parathyroid hormone (PTH) gene.Methods Human PTH gene was amplified by polymerase chain reaction from pcDNA 3.1 -PTH templates and inserted into murine stem cell virus (MSCV) vectors. The plasmids recombinated with PTH gene were transfected into PA317 packaging cells and screened for positive clones with Geneticin. The condensed recombinant retroviruses were obtained and used to infect HSCs coming from umbilical cord blood. The infected HSCs were injected into the mice suffering from HPT. The change of symptoms and serum level of PTH and calcium in each group of mice was observed.Results Human PTH gene was proved to be inserted into MSCV vectors and the titres were up to 2?10 7 colony forming unit (CFU)/ml in condensed retroviral solution. The secretion of PTH reached 15 ng per 10 6 cells per 48 h. The wild type viruses were not detected by PCR amplification. The mice suffering from HPT recovered quickly and the serum level of calcium and PTH remained normal for about 3 months after the HSCs recombinated with PTH gene were injected into them. In the groups of mice subject to the injection of the recombinant retroviruses containing PTH gene, the serum level of PTH and Calcium was significantly increased in a short time, and then declined slowly. And the mice took on the manifestation of hypoparathyroidism again. The mice only subject to the implantation of HSCs were all dead within 20 days.Conclusion A long term therapeutic effect could be obtained by infusing the HSCs which were integrated with PTH gene into the mice suffered from hypoparathyroidism.

PurposeTo evaluate the existence and extent of magnetic resonance(MR) artifacts caused by frequently used metallic dental materials and to compare the influence of different MRI sequences on artifacts.MethodsA total of 22 kinds and 25 metallic dental samples were tested with 1.5 T MR imager and gradient-echo sequence. Spin-echo and fast spin-echo were added to parts of these samples. Results Of all the 25 metallic dental samples, 11 including gold, amalgam, and silver point did not produce artifact. Titanium alloy and porcelain product fused in metal had mild artifacts. Whereas the remaining 12 samples such as the retention pin and pivot pin showed severe artifacts. Artifacts produced by retention pin, nickel chromium crown and so on were less severe on fast spin-echo. ConclusionsAttention should be paid to some of the metallic dental materials, which could cause severe MR artifacts and image degradation, when undergoing face,jaw and head MR examination. Artifacts can be alleviated by using proper metallic materials or choosing proper imaging sequence and parameters.

OBJECTIVETo study the effect of Bushen Tongdu Capsule (BTC) on RANK/RANKL/ OPG pathway of collagen induced arthritis (CIA) rats, thereby laying theoretic evidence for treating rheumatic arthritis (RA) by Chinese medicine.
METHODSRA model was induced by CIA. Totally 42 rats were randomly divided into six groups, i.e., the normal control group, the model group, the low dose BTC (BSL) group, the medium dose BTC (BSM) group, the high dose BTC (BSH) group, and the Tripterygium Glycosides (TG) group, 7 in each group. BTC at the daily dose of 120, 240, and 480 mg/kg was given by gastrogavage to rats in the BSL, BSM, and BSH group respectively from the 13th day of modeling. TG at the daily dose of 24 mg/kg was given by gastrogavage to rats in the TG group. All medication was given once daily, 2 mL each time. Two mL normal saline was administered to rats in the normal control group and the model group. All medication lasted for 18 days. Samples were taken at day 31. The TRAP section of the ankle joint was fixed in 10% formalin for TRAP stain. Serum levels of osteoprotegerin (OPG), receptor activator of nuclear factor-κB ligand (RANKL), and macrophage colony-stimulating factor (M-CSF) were detected using ELISA.
RESULTSCompared with the normal control group, positive reactions of pathological ankle joint section, inflammation, and osteoclasia degree were significantly improved in the model group, serum levels of RANKL and M-CSF were up-regulated, levels of OPG and OPG/RANKL were significantly lowered (all P < 0.01). Compared with the model group, positive reactions of pathological ankle joint section, inflammation, and osteoclasia degree also significantly decreased in the BSH group and the TG group (all P < 0.01). RANKL and M-CSF were significantly down-regulated in each medicated group, while levels of OPG and OPG/RANKL were significantly up-regulated (all P < 0.01). Compared with the TG group, M-CSF was lower, but levels of OPG and OPG/RANKL were significantly up-regulated in the normal control group (all P < 0.01). RANKL and M-CSF were significantly up-regulated, while levels of OPG and OPG/RANKL were significantly down-regulated in the model group and each BS group (all P < 0.01).
CONCLUSIONBTC could relieve bone damage of CIA rats possibly through regulating and controlling osteoclasts.
