The study about the flux and index of gamma-ray loud blazars show:(1)there is significant correlation between the luminosities in gamma-ray and VLBI radio energy band;(2)there are strong anticorrelarions among the observed indices of soft X-ray, hard X-ray and gamma-ray. For the FSRQs, the whole X-ray emission was contributed by synchrotron self-Compton emission, for the HBLs, the X-ray emission was dominated by synchrotron emission while the soft X-ray emission is dominated by synchrotron emission and the SSC emission dominate the hard X-ray energy band for LBLs;(3) there are strong radio-radio and radio-optical flux correlations for the quasar 3C 273. The higher frequency emission leads those in lower frequency. The multi-band complex indices strongly correlated with the high frequency flux which implies that the object is becoming bright when the energy spectrum is harden.

Results The activation of NF-κB, proliferation response, and expression of IL-4 and I L-5 mRNA and protein in T lymphocytes stimulated by PMA were significantly hig her than those of their blank control (P.01), while those indexes of T l ymphocytes stimulated by PMA and PDTC simultaneously were significantly lower th an those stimulated by PMA alone (P.01). The apoptotic index of T lympho cytes stimulated with PMA were significantly lower than that of their blank cont rol (P.01), and the apoptotic index of asthmatic guinea pig T lymphocytes stimulated with PMA and PDTC simultaneously were significantly higher than that stimulated by PMA alone (P.01). The significant positive correlations w ere found between the activation of NF-κB and the proliferation (r=0.64, P.001), and the expression of IL-4 and IL-5 mRNA and protein of T lymph ocytes, respectively (r=0.55-0.68, P.001). There was also signific ant negative correlation between the activation of NF-κB and apoptosis of T l ymphocytes (r=0.62, P.001). Conclusions NF-κB may participate in the signal conduction of PKC regulated proliferation, apoptosis and expression of IL-4 and IL-5 of T lymphocytes in asthma.
