We examine the evolution of quark-gluon plasma（QGP） droplets with viscous hydrodynamics and analyze the pion transverse-momentum spectrum, elliptic flow, and Hanbury-Brown-Twiss（HBT） interferometry in a granular source model consisting of viscous QGP droplets. The shear viscosity of the QGP droplet speeds up and slows down the droplet evolution in the central and peripheral regions of the droplet, respectively. The effect of the bulk viscosity on the evolution is negligible. Although there are viscous effects on the droplet evolution, the pion momentum spectrum and elliptic flow change little for granular sources with and without viscosity. On the other hand,the influence of viscosity on HBT radius Rout is considerable. It makes Rout decrease in the granular source *** determine the model parameters of granular sources using the experimental data of pion transverse-momentum spectrum, elliptic flow, and HBT radii together, and investigate the effects of viscosity on the model parameters. The results indicate that the granular source model may reproduce the experimental data of pion transverse-momentum spectrum, elliptic flow, and HBT radii in heavy-ion collisions of Au-Au at√s（NN）=200 GeV and Pb-Pb at√s（NN） =2.76 Te V in different centrality intervals. The viscosity of the droplet leads to an increase in the initial droplet radius and a decrease of the source shell parameter in the granular source model.

We investigate the squeezed back-to-back correlation（BBC） of D^0~0 in relativistic heavy-ion collisions, using the in-medium mass modification calculated with a self-energy in hot pion gas and the source space-time distributions provided by the viscous hydrodynamic code VISH2＋1. It is found that the squeezed BBC of D^0~0 is significant in peripheral Au＋Au collisions at the relativistic heavy ion collider energy. A possible way to detect the squeezed BBC in an experiment is presented.

Objective To identify a method for health education using the example of an educational seminar on AIDS prevention and control at Hebei Medical University in China, *** Our goal is the theoretical formulation of a unified community approach for problem solving through the combination of the self regulative approach and the case analytical approach. “Quality improvement”, “essential quality” and “human ecosystems” provide the basic ideas for better understanding the integration of culture, science and technology within the “cultural norm”.Results The present seminar was successfully organized for Chinese medical students based on the theme of “living with AIDS”. Through this program, we identified that self regulative and case analytical approach were major issues for holistic approach to health education. We also identified that a community approach provides the scientific basis for health education in the *** The present paper generates a healthcare paradigm for surveillance in health/medical education. Through a better understanding of community approach, we related “community care” (emphasizing self, mutual, professional and institutional care) to the “practical norm”; and “preventive epidemiology” (emphasizing the unification of quality and quantity, as well as systems and population) to the “research norm”.

Objective To investigate the effects ofamiodarone （AMD） on simvastatin （SV） in human liver microsomes and the possible underlying mechanisms. Methods Time-, NADPH- and concentration-dependent inhibitions were tested in HLM. The logarithm of relative inhibition values was plotted versus preincubation time （0, 5, 10, 15, 20min） for a series concentration of AMD used （0, 2, 5, 25, 50 umol/L）, and the slopes determined by linear regression. These slope values represente the observed inactivation rate constants （kobs ）. A double-reciprocal plot was then constructed using the reciprocal of the kobs （y-axis） and the reciprocal of the associated inhibitor concentration （x-axis） to estimate the values of kinact and K1, which were two principal kinetic constants that were specific for mechanism-based inhibition （MBI）.drug-drug interactions （DDI） potential was predicted based on in vitro data and by using the in vitro-in vivo extrapolation. Results The time-, concentration- and NADPH-dependent characteristics confirmed that when SV was the substrate of CYP3A4, the inhibition of AMD to CYP3A4 is MBI. KI and kinact value were calculated to be 5.1umol/L and 0.018minL The CLant of SV was reduced 2.96-5.63 fold when it was administrated with AMD. Conclusion Based on the results, AMD would inhibit SV metabolism via the mechanism-based manner, which would lead to DDI when they are taken together. Careful clinical observation is recommended when AMD and SV have to be simultaneously prescribed.

Post-modernism began to rise in the mid 20th century, and also rapidly played an influence on the cultures of all the countries in the world. Its combination with the design of art in the development process has brought about a new idea for the aesthetic appreciation of people. The combination of postmodernism with fashion design was mainly reflected in sublation. This has exerted a profound influence on the development of fashion design, which is demonstrated in design theme, design idea, and design methods. In this paper, this is introduced from the concept and characteristics of postmodernism, the influence of postmodernism on fashion design, and the reflection of postmodernism in fashion design. It is found that the post-modernism ideological trend plays a certain role in promoting fashion design.

Aim： To study the molecular mechanism of epididymal protease inhibitor （Eppin） modulating the process of prostate specific antigen （PSA） digesting semenogelin （Sg）. Methods： Human Sg cDNA （nucleotides 82-849） and Eppin cDNA （nucleotides 70-423） were generated by polymerase chain reaction （PCR） and cloned into pET-100D/TOPO. Recombinant Eppin and Sg （rEppin and rSg） were produced by BL21 （DE3）. The association of Eppin with Sg was studied by far-western immunoblot and radioautography. In vitro the digestion of rSg by PSA in the presence or absence of rEppin was studied. The effect of anti-Q20E （N-terminal） and C-terminal of Eppin on Eppin-Sg binding was monitored. Results： Eppin binds Sg on the surface of human spermatozoa with the C-terminal of Eppin （amino acids 75-133）. rSg was digested with PSA and many low molecular weight fragments were produced. When rEppin is bound to rSg, then digested by PSA, incomplete digestion and a 15-kDa fragment results. Antibody binding to the N-terminal of rEppin did not affect rSg digestion. Addition of antibodies to the C-terminal of rEppin inhibited the modulating effect of rEppin. Conclusion： Eppin protects a 15-kDa fragment of rSg from hydrolysis by PSA.
