The current study was designed to determine the safety, tolerability and pharmacokinetic parameters of recombinant human parathyroid hormone [rhPTH (1-84)] used for the treatment of osteoporosis. In the single-dose format pharmacokinetic study, thirty-six healthy male volunteers received three dose levels of rhPTH (1-84) subcutaneously: 1, 2, and 4 mug/kg. The blood was timing drawn and the serum concentration of rhPTH (1-84) was determined by enzyme linked immunosorbent assay (ELISA). Serum concentration-time curves of PTH (1-84) exhibited a double-peak pattern, the first peak appearing about 10 to 30 min after administration and the second peak occurring about 1.5 to2 h after administration. Serum terminal half-time of PTH (1-84) was approximately 2 h. The parameters indicated the serum levels were directly proportional to the administered dose, with the mean C(max) and AUC(0-24) ranging from approximately 543.47 to 1845 pg/mL and 2358.6 to 9232.12 pg.h.mL(-1) over the dose range. The drug was well tolerated, the clinical symptoms were generally mild and of short duration.

Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

Objective To investigate the influence of high intensity interval exercise (HIIT) on peroxidation and vascular endothelial function for experimental hyperhomocysteinemia (HHcy) rats. Methods Thirty five male rats were randomly divided into 4 groups. Control group (n=8) was given ordinary feed. High methionine group (n=27) was given 3% methionine on this basis, and divided into model group, folic acid group and HIIT+ folic acid group, with 9 rats per group for 16 weeks. Serum homocysteine (Hcy) , content of plasma malondialdehyde (MDA) , hydroxyl radical (OH-), total antioxidant capacity (T-AOC), activity of glutathione peroxidase (GSH-PX) and superoxide dismutase (SOD) were measured, as well as the level of Nitric Oxide (NO), Nitric Oxide Synthase (NOS) and Endothelin 1 (ET-1) . The pathology of abdominal aortas was analyzed.Results Sixteen weeks after intervention, there was no significant difference between HIIT + folic acid group and the control group (P>0.05) . The levels of serum Hcy in the model group, folic acid group and the HIIT+folic acid group were (23.95±3.35) μmol/L,(8.73±0.60) μmol/L, and (6.19±0.34) μmol/L respectively (P<0.05) . Sixteen weeks after intervention, the content of MDA in HIIT+ folic acid group reduced, and there was no significant difference compared with the control group (P>0.05). The level of SOD and GSH-PX increased in HIIT+ folic acid group and folic acid group, and there was a significant difference compared with the model group. There were significant differences in activities of SOD and GSH-PX in HIIT+ folic acid group when compared with folic acid group (P<0.05). Compared with the control group, there were significant differences in levels of ET-1, NOS and NO in folic acid group (P<0.05), while there was no significant difference in the level of ET-1 and NOS between HIIT+folic acid group and control group (P>0.05) . Mild atherosclerotic lesions were observed in the HIIT+folic group. Conclusion High methionine diet can reduce the level of serum Hcy in HHcy rats, and high intensity interval exercise combined with folic acid intervention could reduce the level of serum Hcy, improve oxidative stress state, reduce the injury of endothelial function, and thus to alleviate atherosclerotic lesion.
