The structure and properties of mixed monolayer or LB film of 5,10,15,20-tetra-4-oxy(2-stearic acid)phenyl porphyrin/C60 were studied. A isotherms and small angle X-ray diffraction (SAXD) results show that C60 molecules were incorporated into the cavities of por-phyrin molecules in mixed monolayer and LB film . UV-vis spectra of mixed LB films show that the absorption intensity of porphyrin varied compared with pure porphyrin film, probably arising from the interactions between C60 and porphyrin ring. C60 molecules in mixed systems are well-dispersed. The TPP(CO2H)/C60 mixed LB film is a kind of two-dimensional host-guest system.

CD134, a member of the tumor necrosis factor receptor superfamily, plays a crucial role in T cell survival. In this study, peripheral blood mononuclear cells （PBMCs） stimulated with phytohemagglutinin （PHA, 50 μg/ml） were treated by CD134 mAb （1μg/ml, 5 μg/ml, 10 μg/ml） for 6 h, 12 h, 24 h and 48 h. The level of perforin mRNA was measured by reverse transcription-polymerase chain reaction （RT-PCR） technique. Our data showed that the expression of perforin mRNA in PBMCs was down-regulated by CD134 mAb in a dose-dependent manner in range of 1 μg/ml to 5 μg/ml and dropped down to its minimum on 24 h （p 〈 0.05）. The level of perforin mRNA reached a plateau when the concentration of CD134 mAb exceeded 5 μg/ml. In conclusion, CD134 mAb can inhibit perforin expression, which may enhance the ability of T cells for survival. Cellular ＆ Molecular Immunology. 2005;2（6）： 467-471.

In this paper, human capital is considered a kind of goods in terms of investment. Basic consumption and profit margin are the two important components of human capital goods value. Compared with that of the material capital, the human capital consumption has the following features. The importance of human capital investment determined by the supply-demand mechanism, is growing gradually; The course of investment and return takes a long period of time; Human capital is characterized by strong technicality and weak negotiability; The investment profit margin is changeable and discriminating.
