Journal of Third Military Medical University 2003;0(15):-
Objective To study the gene expression profiles in cardiac muscles at the early phase after electrical injury. Methods The total RNA in both injured group and control group were isolated and hybridized with BioStar-40 cDNA microarray that contains 4 096 genes or expressed sequence tags (EST) randomly selected from a rat cDNA library. Results A total of 71 genes or ESTs were differently expressed in the cardiac muscles in 3 h after electrical injury with 35 up-regulated genes or ESTs and 36 down-regulated genes or ESTs. Some of these genes were involved in coagulation, inflammation, signal transduction and cell homeostasis. Conclusion The genomic response to heart electrical injury is complex and a great number of genes involved in this pathophysiological process. The analysis of differently expressed genes is helpful to learn the molecular mechanisms of heart electrical injury.

Chinese Journal of Postgraduates of Medicine 2014;37(2):21-23
Objective To investigate the death risk factors of severe cerebrovascular disease.Methods The clinical data of 226 patients with severe cerebrovascular disease were analyzed retrospectively.All of the death risk factors were divided into three types.Type Ⅰ was the uncontrollable factors,including age,gender and family genetic history.Type Ⅱ was morbid risk factors,including hypertension,hyperlipemia,diabetes,valvular heart disease,cardiovascular diseases and history of stroke.Type Ⅲ was life style risk factors,including smoking,drinking,obesity,high salt diet,high protein diet and less movement.The risk factors were evaluated with single factor and multiple factors analysis.Results Single factor analysis showed that age,hypertension,diabetes,history of stroke,smoking,drinking,high salt diet and less movement were the high risk factors (P < 0.01 or < 0.05).Multiple factors analysis showed that age (OR =1.242,P =0.001),history of stroke (OR =2.325,P =0.000),less movement (OR =-1.172,P =0.010) were correlated with the death.Conclusions Severe cerebrovascular disease is associated with multiple factors.Early intervention to the risk factors in patients with severe cerebrovascular disease can effectively decrease the risk of death and reduce the mortality.
4.Dose distribution of oblique incidence electron beam
Chinese Journal of Radiation Oncology 1992;0(01):-
ObjectiveTo analyze the dose distribution of oblique incidence electron beam. MethodsIn water phantom,the relative dose values were measured along the central axis of electron beam. The slope angles of 80% and 50% isodose lines were measured in the penumbra area. All these measured data were compared with those without oblique angle. Results1. When the oblique incidence angle of electron beam increased,the depth of the maximal dose and the isodose lines of 90%,80%,50% and 10% decreased. 2.The higher the beam energy ,the greater the depth of maximal dose and the isodose lines of 90%,80%,50% and 10%. 3.The effect of oblique incidence was also related to field size. When the beam size increased,the depth of maximal dose and the isodose lines of 90%,80%,50% and 10% decreased. 4. For the same oblique incidence angle,the effect of electron energy is more obvious than that of beam size. 5. Because of the oblique incidence of electron beam,the 80% and 50% isodose lines in the penumbral area would slope up to the direction with air gap and the slope angle was wider than the oblique incidence angle of the electron beam. Conclusions The oblique incidence of electron beam not only reduces the depth of maximum ionization,but also weakens the transmissive ability of electron beam. The weakening extent of the transmissive ability is related to electron energy and field size. In the oblique incidence,the movement of 80% and 50% isodose lines in horizontal direction should be noted,otherwise the dose of some tumor will be very low.

Chinese Journal of Biologicals 2024;37(5):571-576
Objective To study the effects of attenuated Salmonella(Ty21a-pIRES-IL-2-NK4,TPIN)carrying interleukin-2(IL-2)/4-kringle antagonist of hepatocyte growth factor(NK4)double gene on humoral and cellular immune function.Methods Eighteen BALB/c mice,half male and half female,were randomly divided into control group(1. 5 mL 10%NaHCO3 by gastric tube feeding),Ty21a group(0. 1 mL Ty21a by gastric tube feeding)and TPIN group(0. 1 mL TPIN by gastric tube feeding),with 6 mice in each group. The immunization was boosted twice 7 d after the initial immunization. At 21d after administration,the blood samples were collected from eyeballs and the serum was separated,which was detected for the serum IgG antibody level by ELISA. The thymus and spleen of mice were isolated aseptically,and the spleen cells were stimulated by Ty21a and TPIN respectively in vitro. After 72 h,the proliferation ability of spleen cells was measured by CCK-8 assay,and the expression level of cytokines in spleen cells was detected by ELISA. The spleen and thymus were weighed,the spleen and thymus indexes were analyzed,and HE staining was performed.Results Compared with the control group and Ty21a group,the serum IgG level(F = 111. 74,P < 0. 01)and the contents of IFNγ,IL-4 and IL-10 in spleen cell supernatant(F = 38. 21,11. 37 and 26. 92,respectively,each P < 0. 05)increased significantly,as well as the spleen and thymus indexes(F = 10. 419 and 5. 859,respectively,each P < 0. 05)showed significant increase. In mice of Ty21a and TPIN group,the thymus cortex widened,lymphocytes increased,and there was mild inflammatory reaction;the white pulp and lymphocytes in spleen increased with neutrophil infiltration.Conclusion TPIN has a good immune protective effect,and can significantly stimulate the body to produce humoral immunity and cellular immunity,which may have a good therapeutic effect on tumors.

9.Network pharmacology: new opportunity for the modernization of traditional Chinese medicine.
Acta Pharmaceutica Sinica 2012;47(6):696-703
Traditional Chinese medicine (TCM) with the characteristics of holistic view and treatment based on syndrome differentiation, has rich clinical experience thousands of years and demonstrates promising effects to cure complex disease. However, due to the features of multi-component, multi-target and synergistic effect existed in TCM, the effective substances and mechanisms of action are not clear, the qualities of TCM are out of control, and scientific and correct assess system is waiting to be established. The network pharmacology is a novel subject based on the construction of multi-layer networks of disease-phenotype-gene-drug to predict the drug targets in a holistic view, and promote efficiency of drug discovery. Methodologically, network pharmacology integrated the notions of comprehensive research and systematic assessment which agree with the characteristics of holistic view and treatment based on syndrome differentiation in Chinese medicine. Our paper reviewed the challenge and chance within the modernization of TCM, the concept and technology of network pharmacology, and its preliminary application in investigation of TCM. The theoretical system of network pharmacology is emphasized, and the potential prospect of its application in modernization in TCM is focused.
