ABSTRACT
Global minimum essential requirements in medical education(GMER) was established by the Institute for Intemational Medical Education(IIME),which consisted of members from all over the world,the GMER should be reached by all of the graduates.This paper analyzes the importance and possibilities that the university of the extrovert type ushers in the international medical education standard,and according to actual work,put forward some suggestions.
ABSTRACT
OBJECTIVE: To provide reference for Chinese pharmaceutical enterprises to promote marketing strategy under the new condition of medical system reform.METHODS: The marketing strategies for pharmaceutical enterprises under the new condition of medical system reform were analyzed systematically from aspects of the pharmaceutical target market,marketing concepts and pricing system.RESULTS & CONCLUSIONS: Under the new medical system,the pharmaceutical enterprises have to reconsider their marketing strategies such as by marching into primary level market,adjusting their marketing concepts from aspects of strengthening brand innovation construction and reorganizing the staff structure of marketing team etc,and adjusting pricing strategy etc to achieve a sustainable satisfactory development.
ABSTRACT
AIM: To study the pathological change in mouse organs immunitied by inactivated SARS-CoV vaccine. METHODS: Inactivated SARS-CoV vaccine was injected into BALB/c and C57BL/6 mice. Anti-SARS antibody was analyzed by ELISA. After 8 weeks, the immunitied mice were killed and those organs were analyzed by pathological methods. RESULTS: Anti-SARS antibody in mice was positive after 8 days. Only minimal injury was observed in a few lungs and livers, but the other organs were not. CONCLUSIONS: Inactivated SARS-CoV vaccine induced mice to create antibody, whereas they did not cause severe injury. This result will be valuable for vaccine into clinical research. [
ABSTRACT
AIM: To investigate the antitumor and immunological activities of the polysaccharides obtained from rabdosia rubescens (RRP). METHODS: In vitro and in vivo tumor inhibitory experiments as well as MTT method were used. RESULTS: With increasing concentration, the RRP exerted direct cytotoxicity effect in vitro on the cell growth of EAC mice,and its inhibitory rate in vivo against sarcoma 180 reached 35% ( P
ABSTRACT
nm-23 gene is the first antimetastatic gene which was found to have close relationship with metastasis and prognosis of many malignant carcinoma.This review briefly summarizes the development of nm-23 gene and hepatocellular carcinoma in recent years.
ABSTRACT
AIM:To study the action of nucleoside diphosphate kinase A(NDPK-A)on the growth of S_ 180,H_ 22,Lewis and H460.METHODS:S_ 180 or H_ 22 cell(5?106)were inoculate subcutaneously into the right armpit of 85 Kunming mice,which were randomized into 8 groups.Lewis lung carcinoma cells(2?105)were inoculate subcutaneously into the right armpit of 85 C57BL/6 mice,which were randomized as Kunming mice.From the 2nd day,the treated groups were given different dose of rhNDPK-A once a day for 8 days(for S_ 180 or H_ 22 by iv)or for 10 days(for Lewis by ip),and the control group was given physiological saline only.H460 tissue pieces about 1.5 mm?1.5 mm?1.5 mm each were inoculated subcutaneously into the armpit of 38 Balb/c/neu mice.After the volume of xenograft become 100 mm?100 mm?100 mm,the nude mice were randomized into 5 groups and given different dose of rhNDPK-A once a day for 17 days.2 days after above treatments,the mice were killed and dissected.The knubs were peeled off and weighted.RESULTS:The growth of S_ 180,H_ 22 and H460 were inhibited by rhNDPK and the growth of H_ 22 was inhibited by rhNDPK at dose of 20 mg/kg combined with cisplatin(0.5 mg/kg).But the growth of Lewis lung cancer was not inhibited.CONCLUSION:rhNDPK-A inhibited the growth of S_ 180,H_ 22 and H460.rhNDPK-A(20 mg/kg)potentiated the antitumor action of cisplatin on H_ 22.
ABSTRACT
AIM: To investigate the behaviour of 3T3 fibroblast and macrophage co-culture on blood fibrin clot or adipose tissue with recombinant basic fibroblast growth factor (rhbFGF). METHODS: MTT method, inverted contrast microscopy, Giemsa staining as well as scanning electron microscope were used in the present study. RESULTS: The effect of rhbFGF on co-culture of 3T3 fibroblast and mouse macrophage on blood fibrin clot in low-serum DMEM with rhbFGF were monitored, and 3T3 fibroblast and macrophage growed well on the blood fibrin blot in low-serum DMEM with rhbFGF. CONCLUSION: The blood fibrin clot, with its low immunogenicity, could be used as a bionic support for three-dimensional tissue culture, and also a physiological carrier to distribute the growth factor rhbFGF for the cells.
