Intra-hepatic and extra-hepatic cholangiocarcinoma:New insight into epidemiology and risk factors

Cholangiocarcinoma(CCA) is a malignant tumour that arises from biliary epithelium at any portion of the biliary *** is currently classified as intra-hepatic or extra-hepatic CCA(EH-CCA).Recent evidences suggest that intra-hepatic CCA(IH-CCA) and EH-CCA are biologically different cancers,giving further support to a number of recent epidemiological studies showing large differences in terms of incidence,mortality and risk *** purpose of this manuscript is to review recent literature dealing with the descriptive epidemiology and risk factors of CCA with a special effort to compare IH-with EH-CCA.

Synthesis, structural model and vibrational spectroscopy of lutetium tricalcium phosphate Ca9Lu(PO4)7

Journal of Rare Earths 2018年第11期36卷 1162-1168页

Lutetium β-tricalcium phosphate Ca9Lu（PO4）7 was synthesized by solid-state reaction at 1200 ℃, and investigated by means of a combination of scanning electron microscopy （SEM） equipped with energy dispersive X-ray spectroscopy （EDS）, X-ray diffraction （XRD）, Fourier transform infrared （FTIR） and Raman spectroscopies. SEM morphological analysis reveals the presence of sub spherical and prismatic micro crystalline aggregates, while EDS semi-quantitative analysis confirms the nominal Lu/Ca compo- sition. The unit cell and the space group were determined by X-ray powder diffraction data showing that the compound crystallizes in the rhombohedral R3c wfiitlockite-type structure, with unit cell constants a - b 1.04164（1） nm, c 3.7302（1） nm and cell volume V 3.5051（1） nm^3. The investigation was completed with the structural refinement by the Rietveld method, and discussion of the distribution of Lu within cationic sites according to the results of the Rietveld refinement. The FIIR and Raman spectra, correlated to isostructural rare earth phosphates from literature, show slight band shifts of the phosphate modes correlated to the evolving size of the rare earth elements.
