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.

AIM: To investigate the amiloride-sensitive Na~+ channel current (Iamil) in primary cultured human bronchial epithelium cells of chronic obstructive pulmonary disease (COPD) patients and the influence of interleukin 4 and interleukin 6. METHODS: Human bronchial epithelium cells were isolated and cultured from 18 patients undergone pueumonectomy in hospital. Interleukin 4 or interleukin 6 at concentration of 10 ?g/L was used to treat these cultured cells, and Iamil was measured by whole cell patch clamp techniques. RESULTS: There was no markedly difference among normal no-smoking group, normal smoking group and COPD group. Interleukin 4 down-regulated the Iamil in normal no-smoking group, normal smoking group and COPD group. The down-regulated percentages were 59.7%, 54.7% and 30.0%. Interleukin 4 down-regulated the Iamil in normal no-smoking group (44.8%) and normal smoking group (34.9%) but not in COPD group, and the current forms were not changed after IL-4 or IL-6 treatment. CONCLUSIONS: Interleukin 4 and interleukin 6 down-regulated the Iamil in primary cultured human bronchial epithelium cells. It may contribute to the hypersecretion of COPD, and the up-regulated interleukin 4 and interleukin 6 in COPD patients may cause them react weaker to the treatment of interleukin 4 and interleukin 6.

AIM: To study the effect of cigarette smoke extract (CSE) on adhesion and migration of human airway epithelial cells and it's mechanism. METHODS: After 24 h culture, the airway epithelial cells were treated with different concentrations of CSE. The rate of cell attachment and the velocity of cell migration were measured. The expression of FIP200 mRNA and protein were analyzed by RT-PCR and Western blotting. RESULTS: CSE inhibited the rate of cell attachment and the velocity of cell migration. Meanwhile CSE increased the expression level of FIP200 mRNA and FIP200 protein. The effects of CSE became more evident with increased concentration of CSE. Expression of FIP200 mRNA and FIP200 protein were positively correlated to the decreased rate of cell attachment and the velocity of cell migration. CONCLUSION: CSE inhibits the rate of cell attachment, the velocity of cell migration and increases the expression of FIP200.

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.
