Methods: Patients with renal anemia were randomly divided into two groups, the ICWM group and the control group, supporting treatment such as dialysis, supplementing of ferrous, foliac acid and vitamin B12, was given to both groups. Additionally, to the ICWM group, 50 IU/kg of EPO subcutaneous injection for twice every week, and oral intake of BJR, one dose per day taken in two parts, were given, and to the control group, EPO alone, 50IU/kg by subcutaneous injecting, 3 times perweek, was given. The therapeutic course for two groups was 3 months. Blood levels of hemoglobin (Hb), hematocrit (Hct), TNF-α were measured before treatment and the therapeutic effect was observed. Results: After treatment, the levels of Hb and Hct increased significantly in both groups (P<0. 01) , comparison between the two groups in Hb and Hct after treatment for 3 months showed significant difference (P<0. 05). The serum level of TNF-α was markedly higher than normal range in both groups before treatment, it significantly lowered after treatment in the ICWM group (P< 0.05), but unchanged in the control group. Conclusion: Combination of BJR and EPO could significantly inhibit the production of TNF-α, this may be an important factor for ICWM in effectively improving sensitivity to EPO.Original article on CJITWM (Chin) 2004;24 (2): 106展开更多

They were reacted with a photoactive arylazide-4-azidobenzoic acid, resulting in photoactive TNF-α and IFN-γ. The infrared （IR） spectra of these products showed the characteristic absorption of an azido group at 2127 cm^-1. By photo-immobilization, this modified TNF-α and IFN-γ were immobilized on polystyrene membranes for cell culture to prepare biomaterials. The micro-morphology of photoactive cytokines was observed with a scanning electron microscope （SEM）. The inhibitory effect on growth of Hela cells and inducing apoptosis activity of these two cytokines were analyzed by growth curve, transmission electron microscope （TEM） and fluorescence active cell sorter （FACS）. The results showed that co-immobilization of IFN-γ and TNF-α had significant inhibitory effect on growth of Hela cells, inhibitory rate up to 82%, and IFN-γ had obviously synergistic action.展开更多
