Splenic lymphoma with villous lymphocytes （SLVL） or splenic marginal zone lymphoma with circulating villous lymphocytes is rare, and prolymphocytic transformation of SLVL is rarer. At present, only one case of SLVL with t（8;14）（q24;q32） translocation has been reported. In this study, we report a case of B- lymphoproliferative disorder with villous lymphocytes harboring t（8;14）（q24;q32） chromosome translocation that we inclined to SLVL with a prolymphocytic transformation. A 73-year-old female showed marked hepatosplenomegaly and high lymphocytosis （lymphocytes 〉 200 × 10^9/L）. The abnormal lymphocytes had short coarse villi and round nuclei with prominent nucleoli. The immunophenotypes showed CD19^＋, CD20^＋, HLA- DR^＋, CD22^＋, CD5^＋, Kappa^＋, CD25^dim, CD71^dim, Lambda, CD7, CD10-, CD23 , CD34, CD33, CD13 , CD14, CDll7, CD64, CD103, and CD11c-. The karyotype showed complex abnormality： 46XX,＋ 3,-10, t（8;14）（q24; q32）lll]/46XX[9]. The cytoplasmic projection, immunological characteristics, and trisomy 3 chromosome abnormality supported the diagnosis of SLVL. However, the presence of prominent nucleoli and high lymphocytosis suggested prolymphocytic transformation, probably as a result of t（8,14） chromosome translocation. In this report, we described an unusual case of B-lymphoproliferative disorder with villous lymphocytes harboring t（8;14）（q24;q32） translocation, which could provide help in the diagnosis and differential diagnosis of B-lymphocytic proliferative diseases.

The relationship between ultrasonic nonlinearity and microstructure of the liner was studied during the whole curing process by ultrasonic transmission method and infrared *** of input instrumentation was minimized by the natural filtering effect of piezoelectric discs and the maximum excitation energy was acquired simultaneously so as to improve the accuracy of the measuring *** experimental results indicate that in the liner curing reaction at40℃ultrasonic nonlinearity parameter decreases gradually after a sharp decline,which is consistent with the outcome of infrared spectroscopy as the curing degree *** research suggests an effective nondestructive approach to detect the curing properties of the liner in a nonlinear ultrasonic way.

Effects of Cr2O3 doping on the microstructure and electrical properties of （ba,Ca）（Zr,ti）O3 lead-free ceramics

引用

Frontiers of materials Science 2016年第2期10卷 203-210页

作者： Xiang XlA Xiangping jiang Chao CHEN Xingan jiang Na TU Yunjing CHEN jiangxi key Laboratory of Advanced Ceramic materials School of Materials Science and Engineering Jingdezhen Ceramic Institute Jingdezhen 333001 China

Lead-free ceramics （ba0.85Ca0.15）（Zr0.1ti0.9）O3-x wt,%Cr2O3 （BCZT-xCr） were prepared via the conventional solid-state reaction method. The microstructure and electrical properties of BCZT-xCr samples were systematically studied. XRD and Raman results showed that all samples possessed a single phased perovskite structure and were close to the morphotropic phase boundary （MPB）. With the increase of the Cr content, the rhombohedral-tetragonal phase transition temperature （TR-T） increases slightly, and the Curie temperature （Tc） shifts towards the low temperature side. XPS analysis reveals that Cr3. and Cr5＊ ions co-existed in Cr-doped BCZT ceramics, indicating the different impact on the electrical properties from Cr ions as ＂acceptor＂ or ＂donor＂. For the x = 0.1 sample, relative high piezoelectric constants d33 （-316 pC/N） as well as high Qm （-554） and low tan6 （-0.8%） were obtained. In addition, the AC conductivity was also investigated. Hopping charge was considered as the main conduction mechanism at low temperature. As the temperature increases, small polarons and oxygen vacancies conduction played important roles.

The Taiwan mountain belt, one of the youngest orogenies in the world, is caused by the collision of the Luzon arc with the Eurasian margin, which leads to post-collisional extension and magmatism in the Northern Taiwan Volcanic Zone(NTVZ). The magma chamber process in this region has not previously been elucidated in detail. In this paper, the textural and compositional features of plagioclase phenocrysts in basalt from the Tatun Volcanic Group(TTVG) were studied to restrict the dynamics of magma system. results show that the magma melts in TTVG are mainly sourced from the underlying MORB-like mantle wedge but influenced by incorporation of subduction components, causing the elevated Sr/Y and ba/Y ratios in magma melts. The subduction components are mainly transported in the form of sediment melt. The plagioclase phenocrysts in the TTVG volcanic rocks are generally coarsely core-sieved with a clear rim. The An contents in the rims of plagioclase are much lower than those of cores, and elevated FeO concentrations are detected in the plagioclase rims. We propose there exists a double-layer magma chamber in this region. The core of the plagioclase was crystalized in the deeper quiescent magma chamber(~21 km), which was subsequently partially dissolved during the ascent of magma melt under H_(2)O-undersaturated condition, forming the typical coarsely sieved texture and synneusis. When this crystal-rich melt migrates into the shallower chamber, water saturation is reached and more sodic plagioclase formed as the rim of phenocryst. Due to the considerably higher fO_(2) in the shallow chamber than in the deeper one, and the distribution of Fe between plagioclase and melt positively correlates with fO_(2), the FeO content in the plagioclase rim elevates in conjunction with increasing fO_(2).

Gross Nitrification Rates and Nitrous Oxide Emissions in an Apple Orchard Soil in Northeast China

引用

Pedosphere 2015年第4期25卷 622-630页

作者： GE Shunfeng jiang Yuanmao WEI Shaochong State key Laboratory of Crop Biology College of Horticulture Science and Engineering Shandong Agricultural University

A better understanding of nitrogen （N） transformation in agricultural soils is crucial for the development of sustainable and environmental-friendly N fertilizer management and the proposal of effective N20 mitigation strategies. This study aimed： i） to elucidate the seasonal dynamic of gross nitrification rate and N20 emission, ii） to determine the influence of soil conditions on the gross nitrification, and iii） to confirm the relationship between gross nitrification and N20 emissions in the soil of an apple orchard in Yantai, Northeast China. The gross nitrification rates and N20 fluxes were examined from march to October in 2009, 2010, and 2011 using the barometric process separation （baPS） technique and the static chamber method. During the wet seasons gross nitrification rates were 1.64 times higher than those under dry season conditions. multiple regression analysis revealed that gross nitrification rates were significantly correlated with soil temperature and soil water-filled pore space （WFPS）. The relationship between gross nitrification rates and soil WFPS followed an optimum curve peaking at 60% WFPS. Nitrous oxide fluxes varied widely from march to October and were stimulated by N fertilizer application. Statistically significant positive correlations were found between gross nitrification rates and soil N20 emissions. Further evaluation indicated that gross nitrification contributed significantly to N20 formation during the dry season （about 86%） but to a lesser degree during the wet season （about 51%）. Therefore, gross nitrification is a key process for the formation of N20 in soils of apple orchard ecosystems of the geographical region.

Weathering geochemistry and palaeoclimate implication of the Early Permian mudstones from eastern Henan Province, North China

引用

Journal of Palaeogeography 2017年第4期6卷 370-380页

作者： jiang-Hai Yang Yuan-Sheng Du State key Laboratory of Biogeology and Environmental Geology China University of Geosciences

Terrigenous clastic sediments are generated by the integration of the Earth surface processes and their deep-time counterparts provide a valuable archive for regional/global climatic, geographic and landscape evolution. It is thus important to read and interpret these deep-time sedimentary records, especially for reconstructing continent climate. Previous studies on the Early Permian sequences from the North China document a dominant control of source chemical weathering on mudstone compositions and its linkage with continent climate conditions. based on the weathering geochemical data of these mudstones, element mobility during weathering can be ordered as Ca 〉 Na ≥ Mg 〉 Sr 〉 K ≥ ba 〉 Rb. The weathering regime in the source area is inferred to be supply-limited according to the estimated continent physical erosion rate and regional tectonic evolution, sedimentation in North China. Further exploration of palaeoclimate implication is presented in terms of variation of high-to-low latitudinal temperature gradient across the Early Permian glacial to post-glacial climate transition.
