1.Research progress of correlation between NF-?B and CPB
Journal of Medical Postgraduates 2003;0(11):-
Nuclear factor kappa B(NF-?B) is an important transcription factor in the expression of many inflammatory media. With the recent progress of molecular biological technique, the modulated mechanism of NF-?B in immunity, stress, inflammatory responses, and the differentiation and growth of lymphocyte has been the focus. This review presents the role of NF-?B in ischemia-reperfusion and cardiopulmonary bypass, and the research progression of intervention therapy in inhibition of the activation of NF-?B is also introduced herein after.

Objective: To seek the direct evidence of myocardial inflammatory activation in a cohort of patient undergoing surgery on cardiopulmonary bypass (CPB). Methods: Twenty patients undergoing surgery on CPB had plasma samples obtained for tumor necrosis factor-? (TNF-?), perioperatively. Myocardial tissue samples were obtained intraoperatively, both pre-and post-CPB. Myocardial nuclear factor ?B (NF-?B) nuclear translocation and plasma TNF-? concentrations were analyzed by standard enzyme-linked immunosorbent assay (ELISA). Cross clamp times, CPB times and the time to extubation were recorded. The change of myocardial NF-?B nuclear translocation and plasma TNF-? concentrations was assessed by analysis of variance (ANOVA). The regression analysis was utilized to define the correlations among the optical densities of NF-?B, concentrations of plasma TNF-?, influencing factors and heart function. Results: (1) Seventeen patients had NF-?B nuclear translocation before initiation of CPB, the optical density (OD) of myocardial NF-?B was significantly increased at the end of CPB in nineteen patients. (2) The correlation between the activity of NF-?B and concentration of TNF-? was signi ficant. (3) The correlation between the activity of NF-?B and clinic outcomes and other influencing factors was not significant. Conclusion: Myocardial inflammatory activation may be present in the patients before CPB. CPB could increase the activity of myocardial NF-?B.

Physiology course has become an important teaching part of non-medical professions in medical colleges,but there are no normative teaching textbooks and the corresponding teaching syllabus for these non-medical professions,which causes teaching contents chaos and affects the teaching effect.According to their attributes and characteristics,the research group explores continuously the physiology teaching contents suitable for non-medical professions,pays attention to contents settings which are common-sense,practical,systematic and flexible,in order to promote physiology teaching development in non-medical professions.

To separate the biological radar echo signals in different breathing modes. Echo signals of bioradar-based vital signs monitoring system were acquired in different breathing modes, and an improved signal separa-tion algorithm was used to obtain respiratory and heartbeat signals as well as their parameters. Under two breath-ing modes, the center frequencies of the signals from the self-adaptive filter were kept consistent with those of heartbeat signals, and the signals with other frequencies were suppressed effectively. The algorithm can be used to sep-arate heartbeat signals while suppress other interference signals effectively. ZHANG Jing and LIU Qian are the first au-thors who contributed equally to the article.

Objective To investigate the method of directed differentiation dendritic cells from embryonic stem cells(ESC) and to amplify high purity DCS in vitro for immunity therapy.Methods E14 ESC line were generated ESC-derived dendritic cells(ES-DC) in complete medium further supplemented with granulocyte-macrophage colony-stimulating factor(GM-CSF) and interleukin-3(IL-3).ES-DCs was used flow cytometry to determine CD11c,CD80,CD86,MHC-Ⅱ cell surface phenotype. Lipopolysaccharide (LPS) were added to induce the ES-DCs matured. The matured ES-DCs was harvested 24 hours later to be identified with morphology, transmission electron microscopy, analyzed by flow cytometry and compared with the immatured ES-DCs phenotype. The antigen presenting was evaluated by mixed lymphocyte responses.Results The ES-DC had obviously dendritic processes under scanning electron microscope . The immature DCs express low level of CD11c(4.33±0.23)%,CD80 (7.62±0.19) %, CD86 (4.77±1.22) % and MHC-Ⅱ (9.68±0.15) %, but the mature DCs express higher lerve of CD11c(47.36±2.68)%,CD80 (74.4±1.47) %, CD86 (29.77±2.00) % and MHC-Ⅱ (87.56±2.75) %. MLR showed that ES-DCs could effectively stimulate lymphocyte to proliferate.Conclusion These results provide evidence that DCs can be generated from E14 ESC with GM-CSF and IL-3, express high level of CD11c,CD80, CD86, MHC-Ⅱ and can effectively stimulate lymphocyte to proliferate. ES cells may become new origin for DCs which provided the immunotherapy.
