This system consists of the Vlasov-Fokker-Planck equation for the dispersed phase (particles) coupled to the incompressible Euler equations modelling a dense phase (fluid) through the friction forcing. Global existence of classical solutions to the Cauchy problem in the whole space is established when initial data is a small smooth perturbation of a constant equilibrium state, and moreover an algebraic rate of convergence of solutions toward equilibrium is obtained under additional conditions on initial data. The proof is based on the macro-micro decomposition and Kawashima's hyperbolic-parabolic dissipation argument. This result is generalized to the periodic case, when particles are in the torus, improving the rate of convergence to exponential.

Methods: MTT assay was used to determine the inhibitory effect of berbamine alone or combined with chemotherapeutic drugs. Flow cytometry was performed to characterize cell cycle profile in response to berbamine treatment. Western blot was used to measure the protein levels of p65, IκB Kinase α (IKKα), TNFAIP3 (A20), IκBα, p-IκBα, cyclinD1, Bcl-2, BAX, Bcl-x L , Bid, and survivin. Results: Berbamine inhibits the proliferation of KM3 cells in a dose-and time-dependent manner. Combination of berbamine with dexamethasone (Dex), doxorubicin (Dox) or arsenic trioxide (ATO) resulted in enhanced inhibition of cell growth. Flow cytometric analysis revealed that KM3 cells were arrested at G 1 phase and apoptotic cells increased from 0.54% to 51.83% for 36 h. Morphological changes of cells undergoing apoptosis were observed under light microscope. Berbamine treatment led to increased expression of A20, down-regulation of IKKα, p-IκBα, and followed by inhibition of p65 nuclear localization. As a result, NF-κB downstream targets such as cyclinD1, Bcl-x L , Bid and survivin were down-regulated. Conclusion: Berbamine inhibits the growth of KM3 cells by inducing G 1 arrest as well as apoptosis. Berbamine blocks NF-κB signaling pathway through up-regulating A20, down-regulating IKKα, p-IκBα, and then inhibiting p65 nuclear translocation, and resulting in decreased expression of the downstream targets of NF-κB. Our results suggest that berbamine is a novel inhibitor of NF-κB activity with remarkable anti-myeloma efficacy.
