Various combinations of diamond, moissanite, zircon, quartz, corundum, rutile, titanite, almandine garnet, kyanite, and andalusite have been recovered from the Dangqiong peridotites. More than 80 grains of diamond have been recovered, most of which are pale yellow to reddish-orange to colorless. the grains are all 100-200 μm in size and mostly anhedral, but with a range of morphologies including elongated, octahedral and subhedral varieties. their identification was confirmed by a characteristic shift in the Raman spectra between 1325 cm^-1 and 1333 cm^-1, mostly at 1331.51 cm^-1 or 1326.96 cm^-1. Integration of the mineralogical, petrological and geochemical data for the Dongqiong peridotites suggests a multi-stage formation for this body and similar ophiolites in the Yarlung-Zangbo suture zone. Chromian spinel grains and perhaps small bodies of chromitite crystallized at various depths in the upper mantle, and encapsulated the UHP, highly reduced and crustal minerals. Some oceanic crustal slabs containing the chromian spinel and their inclusion were later trapped in suprasubduction zones（SSZ）, where they were modified by island arc tholeiitic and boninitic magmas, thus changing the chromian spinel compositions and depositing chromitite ores in melt channels.

Low-dose total body irradiation （LtBI） is used in the treatment of some cancers mainly for immune enhancement rather than cell killing. However, the mechanism underlying LtBI remains unknown. In this study, by analyzing the immune patterns of lymphocytes, we found that the percentage and absolute number of CD4^＋CD25^＋Foxp3^＋ regulatory t cells are markedly decreased in naive mice following treatment with LtBI. On the contrary, the CD4^＋CD44^＋/CD8^＋CD44^＋ effector-memory t cells are greatly increased. Importantly, naive mice treated with dendritic cell-gp100 tumor vaccines under LtBI induced an enhancement of antigen-specific proliferation and cytotoxicity as well as interferon-γ, （IFN-γ） secretion against FIO melanoma tumor challenge, compared to treatment with either the tumor vaccine or LtBI alone. Consequently, the treatment resulted in a reduced tumor burden and prolonged mouse survival. Our data demonstrate that LtBI＇s enhancement of antitumor immunity was mainly associated with selectively decreasing the proportion and number of t regulatory cells, implying the potential application of the combination of LtBI and a tumor vaccine in antitumor therapy.

已有的锻炼行为理论均是以理性决策为基础,认为人们只要意识到锻炼的益处,就会产生参与锻炼的意图、动机,从而进行规律的体育锻炼。然而,行为并非完全由理性系统控制,还受非理性系统的影响。本研究以针对健康行为提出的双加工模型——熟虑-冲动双系统模型为基本理论框架,构建应用于身体活动领域的熟虑-冲动双系统模型并检验。研究一:构建身体活动领域熟虑-冲动双系统模型,构建的模型包括熟虑前因、冲动前因、影响熟虑与冲动对身体活动作用的调节变量。研究二:选择1 519名参与者对身体活动熟虑-冲动双系统模型进行检验,并检验各调节变量。结果显示:1)身体活动的熟虑系统与冲动系统是两个独立的加工过程,身体活动由两个系统共同决定;2)冲动系统与熟虑系统对身体活动的影响,受行为习惯性的调节,行为习惯性越强,冲动作用越小,反之越大;3)冲动系统与熟虑系统对身体活动的影响,受意志品质的调节,意志品质越高,熟虑系统对身体活动影响更大,反之冲动系统起作用更大。

the binding of chelerythrine （CHE） iminium to calf-thymus （Ct） DNA is characterized by hypochromism and bathochromism in the absorption band, enhancement of fluorescence intensity, increase in fluorescence polarization, and the perturbation of the CD spectra of DNA. these changes are characteristic of intercalation. Scatchard plots constructed from fluorescence titration data gave a binding constant of 5.77×10^5 and a binding site size of 3,4 base pairs at 25 ℃. the intercalative interaction is exothermic with a Van＇t Hoff enthalpy of -33.7 kj/mol. In addition, △G =-32.9 kj/mol, and △S =-2.9 j/mol/K. the intercalation of CHE into the DNA helix is enthalpy-driven.
