Three new chromophores with triphenylamine as molecular focal point bearing one, two, or three 4-(n-butyloxystyryl) group(s) at the periphery respectively, (named as T1, T2, and T3) have been synthesized and characterized. It is interesting to find that the fluorescence quantum yield increases from T1 (0.489), to T3 (0.535), and to T2 (0.628) in cyclohexane, meanwhile the lifetime for T3 is shorter than T1 and T2, which is an important characteristic for applications in light emitting diode. Also PMMA (polymethyl methacrylate) film doped with T3 gives stronger fluorescence than T1, and T2. Cyclic voltammetry showed that T3 exhibited lowest oxidation potential of 0.52 V vs SCE, suggesting its better hole-transport property.

The thermodynamic behavior of twin-roll casting （TRC） lead alloy strip process directly affects the forming of the lead strip, the quality of the lead strip and the production efficiency. However, there is little research on the thermodynamics of lead alloy strip at home and abroad. The TRC lead process is studied in four parameters： the pouring temperature of molten lead, the depth of molten pool, the roll casting speed, and the rolling thickness of continuous casting. Firstly, the thermodynamic model for TRC lead process is built. Secondly, the thermodynamic behavior of the TRC process is simulated with the use of Fluent. Through the thermodynamics research and analysis, the process parameters of cast rolling lead strip can be obtained： the pouring temperature of molten lead： 360-400 ℃, the depth of molten pool： 250-300 mm, the roll casting speed： 2.5-3 m/min, the rolling thickness： 8-9 mm. Based on the above process parameters, the optimal parameters（the pouring temperature of molten lead： 375-390 ℃, the depth of molten pool： 285-300 mm, the roll casting speed： 2.75-3 m/min, the rolling thickness： 8.5-9 mm） can be gained with the use of the orthogonal experiment. Finally, the engineering test of TRC lead alloy strip is carried out and the test proves the thermodynamic model is scientific, necessary and correct. In this paper, a detailed study on the thermodynamic behavior of lead alloy strip is carried out and the process parameters of lead strip forming are obtained through the research, which provide an effective theoretical guide for TRC lead alloy strip process.

To study the radioiodinating condition of interleukin-8(IL-8) and observe its biodistribution in mice for understanding the possibility of its application in nuclear medicine, we labelled IL-8 with 125I using Bolton-Hunter reagent, and the distributions in mice at 5 min, 30 min, 1h, 6h and 24h after injection of 125I –IL-8 were measured. The blood clearance curve was obtained and fitted with the two-compartment model. The results showed that 125I-IL-8 was obtained with a labeling efficiency of 12.2% ±6.5% and a radiochemical purity of 91.4%±6.5%. Its spe- cific activity was 14.8 kBq/μg IL-8. A fast phase half – life T1/2 of 0.32 h and a slow phase half – life T1/2 of 8.01 h α β were calculated from the blood clearance curve. The uptakes of radioactivities in kidneys and lung had the peaks of 85.87%ID /g and 16.17%ID /g at 30 min after intravenous injection, respectively. The uptakes in liver and spleen were 12.05%ID /g and 8.97%ID /g as the maximum at 5 min after injection. The clearance in blood and other organs was fast. Except for kidneys and lung, 125I –IL-8 was less than 1%ID/ g 24 h after administration. It is concluded that radioiodinated IL-8 is a promising radiopharmaceutical in nuclear medicine, especially for imaging infection. But to enhance the labeling efficiency of radioiodinated IL-8 and to decrease its in vivo deiodination are the subjects neces- sary to be further investigated.

The apoptosis in human bone tumor cells induced by internal irradiation with 153Sm was studied. The morphological changes in bone tumor cells were observed by electronic and fluorescent microscopy, as well as DNA agarose gel eletrophoresis. DNA chain fragmentation, microautoradiographic tracing and the inhibition rate of prolif- eration in bone tumor cells exposed to 153Sm with different duration time were examined. It was demonstrated that the bone tumor cells exposed to 153Sm displayed nuclear fragmentation, pyknosis, margination of condensed chroma- tin, and formation of membrane bounded apoptotic bodies, whereas the percentage of DNA chain fragmentation of bone tumor cells increases in direct proportion to the duration of irradiation with153 Sm, as well as DNA ladder for- mation in apoptotic cells. Also a marked inhibition effect of proliferation in bone tumor cells after exposure with 153Sm was observed.

The comet assay (single cell gel electrophoresis assay) was used to evaluate the radiotoxicity of Augerelectron emitters in the human osteosarcoma cell line (HOS-8603). After internal exposure to 67Ga-EDTMP, the sar-coma cell has been injured severely. The comet length was longer along with the increase of dose, the appearance ofcomet tail was different from that with respect to the 60Co γ-ray irradiation. DNA damage of cell was mainly due tothe radiation effect of Auger electrons. The 67Ga may be a therapeutic radionuclide with good prospect for tumortreatment and palliation of bone pain induced by metastasis.

AIM：To prepare the effcient tumor-DC vaccines,dendritic cells(DC) derived from 6-8 weeks Balb/c mice bone marrow progenitor cells were pulsed by apoptotic SP2/0 tumor cells and induced maturation by SP2/0 tumor lysates supermatants. Then SP2/0 tumor burdening Balb/c mice were immunized by the tumor-DC vaccines to observe the therapeutic effects in ***:Immature DC were derived by recombinant murine GMCSF and IL-4,then were pulsed by SP2/0 apoptotic cells. Tumor-DC vaccines were stimulated by LPS and SP2/0 tumor lysates supernatants by four cycles repetitive freezing and thawing,respectively. [^3H]-thymidine incorporation test and standard 4h [^51Cr] release assay were used to detect the proliferation and activation of cytotoxic T lymphocytes (CTL) stimulated by DC in vitro.(4-5)×10^5 DC were immunized in the right inguen of SP2/0 tumor burdening Balb/c mice and most mice received three cycles immunization every two weeks. Changes of the tumor and mice lifespans were recorded .RESULTS:In vitro proliferation and activation of CTL induced by the tumor-DC vaccines of tumor lysates supernatants or LPS stimulation group were more powerful than other groups (P<0.05). According to the regression of tumor and the life-spans of tumor burdening mice,therapeutic effects of tumor lysates supernatants stimulation group were the best, compared with other groups(P<0.05).CONCLUSION:Tumor-DC vaccines,pulsed by apoptotic SP2/0 tumor cells and induced maturation by tumor lysates supernatants,could activate the efficient tumor specific immunity and prolong the life-span of tumor burdening mice.
