Fermion particle pair production in strong SU（2）-gauge chromoelectric fields is studied using the Boltzmann-Vlasov equation in a classical way. The existence of a preproduction process in a classical description is shown using the distribution evolution of non-Abelian particle production. It is interesting to find that the distribution of the particle number density is centered on two islands and shows a split on the color charge sphere as it evolves, ultimately reaching a steady state that is related to the amplitude and variation of the field.

Objective: To explore the correlation between tumor-associated macrophages and the proliferation and invasion of type endometrial carcinoma. Methods: Immunohistochemistry was used to investigate the infiltration of macrophages in normal and different types of hyperplastic endometrial lesions. The proliferation and invasion ability of type endometrial carcinoma cell line RL95-2 influenced by mononuclear macrophage cell line THP-1(constructed M2 type macrophages) was detected by CCK8 and transwell technologies respectively. Transwell was used to evaluate the recruiting ability of RL95-2 on THP-1 cells. Otherwise, the western blot was also used to detect the expression of Cyclin D1 and MMP-2 in RL95-2 with the influence of THP-1. Results: Immunohistochemistry result showed a positive correlation between the number of infiltrating macrophages and the progression of endometrial ***-1 recruited by RL95-2 could promote its proliferation and invasion and enhance the expression of the Cyclin D1 and MMP-2 protein in a time dependent manner(P<0.05). Conclusions: Increase of the number of infiltrating macrophages and its contribution to the tumor inflammatory microenvironment may result in the development of the type endometrial carcinoma.

Data were collected in different successional stages using a simultaneous sampling method and analyzed through quantitative classification method. Three large groups and 12 classes were made to represent the community patterns of three succession stages and 12 succession communities. The succession series of plant community in the study area was as follows: saline bare land→community Suaeda salsa→community Tamarix chinensis→grassland. Succession degree and succession process of 12 succession communities were calculated. Most of these communities were in the lower succession stage, however, community Phragmites communis+Glycine soja and community Imperata cylindrica+G. soja were close to the succession stage of grassland climax. Five species diversity indices were used to study the changes in species richness, species evenness and diversity during succession of community. Heterogeneity index and richness index increased gradually during the community succession process, but species evenness tended to decrease with succession development. The relation between succession and environment was studied by ordination technique, and the results showed that the soil salt content was an important factor to halarch succession of the modern Yellow River Delta. It affected community structure, species composition and succession process.

Massless quark pair production in SU(2) gauge chromoelectric field is investigated by solving the Wigner function with back reaction. The temporal evolution of specific field and its current are obtained self consistently. For the quark distribution function, both its time and momentum dependence are studied. In particular, some interesting phenomena are found, for example, the more abundant symmetry or/and antisymmetry characteristics, the existence of the attractive basin structure and the existence of the momentum "gap" in the quark distribution and so on. All the phenomena are associated with the quark-gluon plasma oscillation, which due to the back reaction effect. The study and analysis qualitatively about the components of the Wigner function are expected to be helpful to deepen the understanding of the QCD vacuum.

Spatial characteristics of Thomson scattering spectra are studied for an electron moving in the circularly polarized laser field in the presence of a strong uniform magnetic field. The results show that the angular distributions of the spectra with respect to the azimuthal and polar angles exhibit different symmetries, respectively, which depend on the fields and electron parameters sensitively and significantly. Moreover, for relatively large parameters such as high laser intensity, high magnetic resonance parameter as well as large initial momentum of electron, the two lobes in spectra tend to the laser-propagating direction so that the radiation can be collimated in the forward direction. Furthermore, an important finding is that by choosing the appropriate fields and initial momentum of electron, the high frequency part of the Thomson scattering spectra can reach the frequency range of soft x-ray,in which a high radiation power per solid angle as ~10^11 a.u. can be obtained.
