The paper was designed to consider the effect of vitamin E on metabolism of cyclic nucleotide in cold exposed male rats. The urinary excretion of cyclic nucleotide was investigated by radioimmunoassay after male rats treated with vitamin E in 4℃ exposure. The results showed that urinary excretion of cyclic nucleotide had been increasing and cAMP/cGMP ratio had been not changing in cold exposed male rats. When one week of the experiment vitmin E could increase urinary cAMP excretion more in its treated group than cold exposed group alone (P

Objective:To study the relationship between MMPs and the metastasis and the malignant degree of tumors in children.Methods:The expression of MMPs in different tumor groups was measured by means of immuno-histochemistry.Results:The expressions of MMP-3 in cytoplasm of tumor cells were observed.There was significant difference( P

?AIM:To improve the efficiency and quality of teaching, and to cultivate students’ ability to analyze and solve clinical problems, the case - based learning ( CBL ) combined with problem-based learning ( PBL ) teaching mode is introduced into the clinical teaching of ophthalmology.?METHODS:Two classes ( total 131 students ) of 2013 grade major in clinical medicine, Kunming Medical University, were randomly selected as experimental group using CBL combined with PBL teaching mode, and control group using traditional teaching mode. The part of acute angle-closure glaucoma was taught. The scores of the experimental group were compared with that of control group at the end of term.?RESULTS:The mean scores of CBL combined with PBL teaching group were significantly higher than that of traditional teaching group.?CONCLUSION: The application of CBL combined with PBL in the clinical teaching of ophthalmology has obvious advantages in improving the learning interests and promoting students’ self-learning ability. It is helpful in improving the students’ ability of independent-thinking, analyzing and solving problem.

Objective To investigate the changes and clinical signficance of nitric oxide(NO) and endothelin(ET) in children with lymphoma.Methods NO and ET of 39 cases with lymphoma and 33 normal controls were examined by using nitrose reductase method and RIA method.Results Compered to normal controls,NO and ET were higher in children with lymphoma;smilar to normal controls in complete remission(CR) and partial remission(PR);relapse cases were higher than remission.Conclusions NO and ET could have relation to lymphoma in children,testing the changes of NO and ET have signficanc to the assistant diagnosis,observeing effect and judging prognosis.
