RESUMO
Objective: To develop a efficient management system of medical equipment through utilized informational and intelligent technique in achieving scientific management of whole life cycle of medical equipment so as to enhance the operating efficiency of hospital. Methods: Through combined the existing management model of medical equipment and experience of hospital, and utilized many kinds of program languages to develop a software, and then to test and improve it in the interior of hospital. Results: The developed management system of medical equipment was able to implement accurate and efficient management throughout the processes of whole life circle, included of purchase, technique, economic calculation, quality control, risk assessment and disposition of scrapped equipment, of medical equipment of hospital. Conclusion: Management system of medical equipment is powerful tool and assistant of the decision maker of hospital, management department of medical equipment and the department of using equipment.
RESUMO
Aim To observe homoharringtonine(HHT) distribution in eyeball tissue of rabbit. Methods Harringtonine(HT) was used as internal standard. The chromatography consisted of Kromasil C18 column with methanol 0.01mol?L-1 (60∶40,pH 2.5) as the mobile phase at the flow rate of 0.8ml?min-1. Results The chromatography retention time of HHT and HT were 6.35min and 4.70min. The standard curve was linear in the concentration range of 5～200 ?g?L-1 in serum and the relation coefficient was 0.994. The recovery of spiked sample was(93.17?4.31)%. After injection of 2mg of HHT in side of rabbit eyeball, the contents in sclera, cornea, retina, vitreous body and crystalline lens were reduced progressively, but the eliminate rate were reduced in a proper order. Conclusion HHT can distribute to every eyeball tissue when it was injected in side of rabbit eyeball.
