Interleukin 24(IL 24),also called the melanoma differentiation associated gene 7(MDA 7),is stably expressed in human tissues associated with the immune system such as the spleen,thymus,peripheral blood leukocytes and normal melanocytes. IL 24 binds to IL 20 and IL 22 receptor complexes(IL 22R1/IL 20R2 and IL 20R1/IL 20R2),and induces secretion of high levels of IL 6,TNF alpha,and IFN gamma and low levels of IL 1beta,IL 12,and GM CSF from human PBMC. Adenoviral IL 24(Ad IL 24) induces growth suppression and apoptosis selectively in diverse human cancers and tumor cell lines without producing any apparent harmful effect in normal cells. The effects of Ad IL 24 are associated to the ratio of pro apoptotic(BAX,BAK) to anti apoptotic(Bcl 2) proteins,and the up regulation of p38 MAPK and a family of growth arrest and DNA damage(GADD) inducible genes. These demonstrate the potential therapeutic effects of Ad IL 24 in human cancer.

The effect of cigarette smoke extract (CSE) on the proliferation of human airway epithelial cells and the possible mechanism was studied. After airway epithelial cells were treated with different concentrations of CSE for 24 h, the cell proliferation was measured by MTT and the distribution of different cell cycles by flow cytometry. The FAK expression level was detected by Western blot and the degree of tyrosine phosphorylation by immunoprecipitation. The results showed that CSE could inhibit the proliferation of human airway epithelial cells, arrest the epithelial cells in G1 phase of cell cycle, dramatically decrease the number of epithelial cells in S and G2 phases; Meanwhile CSE could decrease the expression level of FAK and the degree of its tyrosine phosphorylation. The above effects of CSE were concentration-dependent. The expression of FAK and the degree of its phosphorylation was positively correlated to the increased number of epithelial cells in G1 phase, and negatively to the number of epithelial cells in S and G2 phases. It was concluded that the mechanism by which CSE could inhibit the proliferation of human epithelial cells was contributed to the increased expression and activation of FAK.

The present study used the experimental patterns of Go/No Go and no motion contingent negative variation (CNV) task into the research in order to study whether the CNV can express the implication of expectation. Through comparing the CNV under different conditions, the data collected from experiment showed that the key to evoked CNV was close to the warning signal and command signal. Whether the command signal was related to the task would impact on the amplitude of the CNV. This characteristics responses to the subjects' expectation. On this basis, CNV can be used as the electrophysiological index for the reflection of expected value in the conditions of this experiment.

AIM: To study the role of adrenomedullin(AM) in the pathogenesis of hypoxic pulmonary hypertension. METHODS: Rats were exposed to chronic hypoxia for 14 days. After the measurement of the right ventricular systolic pressure (RVSP), the rats were executed. The weight of the right ventricle (RV), the left ventricle(LV) and the ventricular septum(SP) were determined. The ration RV/(LV+SP) was used to express the thickness of RV. In situ hybridization was used for the detection of the expression of AM mRNA in the lung and RV. RESULTS: The RVSP in the hypoxic group was (63.63?3.42) mmHg,which was significantly higher than that in control group [(34.13?3.40) mmHg]. The RV/(LV+SP) in hypoxic group was 0.439?0.039,which was increased obviously when compared with that of control (0.230?0.025). The level of AM mRNA expressed in the RV in the hypoxia group was significantly higher than that in the control group. CONCLUSION: The expression of AM mRNA in RV increased in the hypoxic condition, which suggests that AM may attenuate the inappropriate increase in pulmonary artery pressure.
