Journal of Practical Radiology 2001;17(1):41-43
Objective:To evaluate the value of DSA in diagnosis of intestinal vascular malformation.Methods:The clinical and DSA characters in 8 patients with small intestinal malformation were analyzed.There were 6 males and 2 females.All patients were underwent selective and supper selective superior mesenteric inferior mesenteric or colic artery angiographies.Results:The clinical fectures:1)the main sympton is acute lower gastrointestinal bleeding;(2)the results of conventional examination were generally negative;(3)the hemoglobin was dropped down to 4~6 g/ml in a short period.DSA feactures included:(1)artery-vein fistula;(2)markedly stainning in local small intestinal walls;(3)abnormal hyperplasia and distubance of small vessels.Conclusion:DSA is the most valuable method in diognosis of atute intestinal bleeding.
4.Lipopolysaccharide stimulates TNFα and endothelin- 1 secretion from cultured rat kupffer cells
Chinese Journal of Pathophysiology 2000;16(12):1298-1300
AIM:To investigate LPS(lipopolysaccharide)stimulated cytokine secretion from normal rat kupffer cells in vitro. METHODS: Kupffer cells were isolated from wistar rats liver and cultured. Tumor necrosis factor - α (TNF- α) and endothelin- 1 (ET- 1 ) secreted by LPS stimulated kupffer cells were detected. RESULTS: LPS had an stimulative effect on kupffer cell activity. LPS in definite concentrations promoted kupffer cell secretion. CONCLUSION: LPS promotes kupffer cell secretion, which may be associated with liver injury induced by LPS.

7.Exploration of Reform of Experiment Teaching Mode in Pharmaceutical Analysis for Pharmacy Major in Sec-ondary Vocational Education School
China Pharmacy 2015;(30):4303-4305
OBJECTIVE:To investigate the reform mode of experiment teaching in pharmaceutical analysis in the new situation of vocational education and provide reference for improving the teaching quality of secondary vocational education. METHODS:The present situation of experiment teaching in pharmaceutical analysis was assessed deeply and in detail,and the problems exist-ing in teaching were analyzed;the reform plan and measures according to the disadvantages of the current teaching were raised. RE-SULTS:The experiment teaching in pharmaceutical analysis existed some problems,involving lagging textbook compilation,single teaching mode,“heavy theory,light practice”for time arrangement,obsolete laboratory apparatus and lack of advanced equipments. So a series of measures were adopted,including writing supplementary teaching materials and experimental guidance;reforming the contents of the experiment teaching;reforming the model of teaching and improving the students’participation;reforming the time arrangements;increasing the investment in laboratory equipment and attaching great importance to extramural cooperation;estab-lishing the virtual laboratory;and establishing a flexible,comprehensive and effective experimental evaluation mechanism.CON-CLUSIONS:Reform experimental teaching mode has fully mobilized the enthusiasm and initiative of students and improved the abil-ity of operating skills,and cultivated the strict scientific research style of students. The reform mode of experimental teaching in pharmaceutical analysis is in accordance with the students’learning needs of pharmaceutical majors,and lay a good foundation for the students better and faster adaption to the job.
