BACKGROUND:Pulsed laser deposition synthesis technology has been used to prepare new nano-hydroxyapatite thin film coating by colagen deposition on artificial mechanical heart valve. OBJECTIVE: To investigate the toxicity of new nano-hydroxyapatite thin film on human umbilical vein endothelial cels. METHODS: Human umbilical vein endothelial cels were cultured with nano-hydroxyapatite film room-temperature leaching solution, nano-hydroxyapatite film high-temperature leaching solution, high-density polyethylene and phenol solution. Within 72 hours, cel growth was observed under the inverted phase contrast microscope. At 7 days after culture, cel proliferation and toxicity grading were detected using Cel Counting Kit-8. RESULTS AND CONCLUSION:At 24 hours after culture, cels grew wel, showed fusiform shape, and had strongrefraction in the nano-hydroxyapatite film room-temperature leaching solution, nano-hydroxyapatite film high-temperature leaching solution, high-density polyethylene groups, and no significant differences in cel morphology and number were detected among above groups. Cels in the phenol solution group were suspended, round, pyknotic and dead. At 48 hours, except phenol solution group, cel number increased significantly, and cel grew densely in other three groups. At 72 hours, cels grew strongly, and the gap became smal obviously. Within 7 days after culture, cel proliferation activity was not significant in the nano-hydroxyapatite film room-temperature leaching solution, nano-hydroxyapatite film high-temperature leaching solution, and high-density polyethylene groups, which was significantly higher than in the phenol solution group (P < 0.05). The toxicity of nano-hydroxyapatite film graded 0 to 1. These results suggested that nano-hydroxyapatite artificial mechanical heart valve has good histocompatibility, but no toxicity.

OBJECTIVE:To provide reference for promoting the development of related legislation work on ensuring pediatric drug use in China. METHODS:The legislation process of pediatric drug use in US,the effects of current Best Pharmaceuticals for Children Act and Pediatric Research Equity Act on pediatric drug use in US were intrduced and analyzed,suggestions on guarantee-ing the accessibility and safety on pediatric drug use in China were put forward. RESULTS & CONCLUSIONS:The policy6-month period of pediatric exclusive protectionin Best Pharmaceuticals for Children Act has motivated the enthusiasm of phar-maceutical companies developing pediatric studies,while it affects the marketing of generic drugs. Pediatric Research Equity Act has achieved remarkable effect in terms of ensuring the safety of pediatric drug use by forcing pharmaceutical companies to carry out pediatrics assessments,while there is no enough force for the marketed drugs that has not been widely used for children. En-couragement and enforcement are useful methods for promoting development of pediatric drug use. It is suggested to take measures like modifingone drug two formsin Prescription Management Regulations,accelerating approvals of related pediatric drugs on the premise that safety is guaranteed,implementing tax preference for related pharmaceutical companies that produced pediatric drugs,promoting the entry of drug reimbursement list and empowering CFDA to force pharmaceutical companies to implement pedi-atric studies to promote the accessibility and safety of pediatric drugs.
