Strata of the Late Cretaceous Niobrara Formation and Pierre Shale Group include bentonites that provide a distal record of volcanic activity taking place to the west. Detailed stratigraphic analysis combined with mineralogy and geochemistry of the bentonites indicates the following timing of events: 1) Eustatic sea level fall as a result of the end of the Niobrara Cycle;2) Tectonic deformation of the Western Interior Seaway coincident with tectonism on the Absoroka Thrust in Wyoming and Late Canyon Range Thrust in Utah;3) Backarc volcanism in Montana associated with the Little Elkhorn Mountain volcanic complex;4) Forearc volcanism in the Cascades area indicates subduction of a hot oceanic crust where plagioclase in the oceanic crust is being incorporated into the melt;5) Cessation of tectonic activity results in a return of sedimentation patterns to north-south trending belts with the Boyer Bay and Burning Brule members of the Sharon Springs Formation deposited to the east and the Mitten Black Shale Formation deposited in the basin.

Tight focusing properties of an azimuthally polarized Gaussian beam with a pair of vortices through a dielectric interface is theoretically investigated by vector diffraction theory. For the incident beam with a pair of vortices of opposite topological charges, the vortices move toward each other, annihilate and revive in the vicinity of focal plane, which results in the generation of many novel focal patterns. The usable focal structures generated through the tight focusing of the double-vortex beams may find applications in micro-particle trapping, manipulation, and material processing, etc.

Asthma and chronic obstructive airway disease ,（COAD） are chronic inflammatory disorders of the airways which are usually associated with widespread airway obstruction that is often relieved by treatment. β2-adrenoreceptor agonists and corticosteriods are the mainstay of the management of this disease. The preferred route of administration of these agents is by inhalation. This allows the drug to be delivered directly to the airway with more rapid relief and fewer side effects than systemic route. The main disadvantage of metered-dose inhaler （MDI） use is that the correct use requires good technique;

目的探讨教师多维态度对全纳教育模式下语前聋人工耳蜗植入儿童教育安置中的作用及影响。方法选取2010年以来山西省人民医院行人工耳蜗植入术后采用随班就读安置的语前聋儿童60名,以教育安置效果是否满意划分为2组,记录全纳教育教师的多维态度量表(teacher’s multidimensional attitudes towardinclusive education scale,TMATIES)得分。结果全纳教育模式下,两组儿童教师多维态度量表得分存在显著差异(P0.05);教师多维态度是影响语前聋人工耳蜗植入儿童教育安置效果的正相关因素(rs=0.381,P1,CI:1.069~1.268,P0.05)。结论语前聋人工耳蜗植入儿童全纳教育状态下,应持续提升教师多维态度的积极性,可提高全纳教育安置效果的满意度。

Previously, we established a model in which physiologically adequate function of the autologous β cells was recovered in non-obese diabetic （NOD） mice after the onset of hyperglycemia by rendering them hemopoietic chimera. These mice were termed antea-diabetic. In the current study, we addressed the role of T regulatory （Treg） cells in the mechanisms mediating the restoration of euglycemia in the antea-diabetic NOD model. The data generated in this study demonstrated that the numbers of Treg cells were decreased in unmanipulated NOD mice, with the most profound deficiency detected in the pancreatic lymph nodes （PLNs）. The impaired retention of the Treg cells in the PLNs correlated with the locally compromised profile of the chemokines involved in their trafficking, with the most prominent decrease observed in SDF-1. The amelioration of autoimmunity and restoration of euglycemia observed in the antea-diabetic mice was associated with restoration of the Treg cell population in the PLNs. These data indicate that the function of the SDF-1/CXCR4 axis and the retention of Treg cells in the PLNs have a potential role in diabetogenesis and in the amelioration of autoimmunity and β cell regeneration in the antea-diabetic model. We have demonstrated in the antea-diabetic mouse model that lifelong recovery of the β cells has a strong correlation with normalization of the Treg cell population in the PLNs. This finding offers new opportunities for testing the immunomodulatory regimens that promote accumulation of Treg cells in the PLNs as a therapeutic approach for type 1 diabetes （TID）.
