BACKGROUND: Hilar cholangiocarcinoma is a devastating disease. Surgery is the only potentially curative modality. How.ver, the results of surgical resection for hilar cholangiocarcinomas are disappointing. The introduction of liver transplantation for this condition has brought new.hope for the management of this disease. The aim of this review.is to discuss the role of liver transplantation in this disease. DATA SOURCES: A MEDLINE search w.s conducted for the articles on liver transplantation for hilar cholangiocarcinoma. Their results have been compiled and compared w.th the existing literature on resection for this disease. RESULTS: The earlier series on liver transplantation for hilar cholangiocarcinoma w.re not encouraging because of poor patient selection. The Mayo Clinic protocol of neoadjuvant chemoradiation follow.d by liver transplantation has show. remarkable success (survival at 1-, 3-, and 5-year post-transplantation being 92%, 82%, and 82%, respectively). w.th better patient selection and integration of neoadjuvant chemoradiation, the long-term survival is superior to that of the patients w.o undergo resection, as show. by the published literature on resection. The limitations of organ availability can be overcome by the living donor liver transplantation programme. This review.article discusses the rationale, pros and cons of liver transplantation vis-à-vis resection for hilar ***: Liver transplantation, especially living donor liver transplantation, is a new.and exciting alternative to resection for hilar cholangiocarcinoma. Integration of neoadjuvant chemoradiation has the potential to further improve the curative potential of liver transplantation. The strategy of combining neoadjuvant chemoradiation and liver transplantation brings new.hope for the treatment of this difficult disease.

The Xianshuihe fault zone is a seismo-genetic fault zone of left-lateral slip in Southw.st China. Since 1725, a total of 59 Ms ≥ 5.0 earthquakes have occurred along this fault zone, including 18 Ms 6.0–6.9 and eight Ms ≥ 7.0 earthquakes. The seismic risk of the Xianshuihe fault zone is a large and realistic threat to the w.stern Sichuan economic corridor. Based on previous studies, w. carried out field geological survey and remote sensing interpretation in the fault zone. In addition, geophysical surveys, trenching and age-dating w.re conducted in the key parts to better understand the geometry, spatial distribution and activity of the fault zone. w. infer to divide the fault zone into tw. parts： the northw.st part and the southeast part, w.th total eight segments. Their Late Quaternary slip rates vary in a range of 11.5 mm/a –（3±1） mm/a. The seismic activities of the Xianshuihe fault zone are frequent and strong, periodical, and reoccurred. Combining the spatial and temporal distribution of the historical earthquakes, the seismic hazard of the Xianshuihe fault zone has been predicted by using the relationship betw.en magnitude and frequency of earthquakes caused by different fault segments. The prediction results show.that the segment betw.en Daofu and Qianning has a possibility of Ms ≥ 7.0 earthquakes, w.ile the segment betw.en Shimian and Luding is likely to have earthquakes of about Ms 7.0. It is suggested to establish a GPS or In SAR-based real-time monitoring netw.rk of surface displacement to cover the Xianshuihe fault zone, and an early w.rning system of earthquakes and post seismic geohazards to cover the major residential areas.

The last meal of sarcophagous maggots may be useful in identifying the species on w.ose flesh they have fed （the＂host＂species）. The DNA profile of the host species may indeed be detectable in the＂last meal＂. In this paper, mitochondrial DNA analysis of gut contents w.s used to identify the prior host of post-feeding larvae of Aldrichina grahami （Aldrich）（Diptera： Calliphoridae）. A modified logistic equation w.s fitted to estimate the probability of identifying the host under five different constant temperatures （16, 20, 24, 28 and 32 ℃）. Our results show. that the detected time ranged from a maximum of 24 h at 32℃ to 42 h at 16℃ and a minimum of 12 h at 32~C to 30 h at 16℃. Furthermore, the host detection time w.s also calculated to give the maximal time after larval hatching from the egg. These results indicate that, in criminal cases w.ere the maggots stray from the corpse, the last meal of the larvae should not be overlooked as potentially critical evidence.

Geochemical characteristics of the Chagande＇ersi molybdenum deposit in Inner Mongolia and its genesis w.re analyzed in this study using rock mineralography and rock geochemical testing. The mineralized country rocks of the Chagande＇ersi molybdenum deposit consist mainly of medium- to fine-grained monzogranite, medium-to fine-grained rich-K granite, w.th minor fine-grained K- feldspar granite veins and quartz veins. The rocks are characterized by high silica, rich alkali, high potassium, w.ich are favorable factors for molybdenum mineralization. The rocks have the Rittmann index ranging from 1.329 to 1.961, an average Na20＋K20 value of 7.41, and AI2Oa/（CaO＋Na20＋K^O）〉1, suggesting that the rocks belong to the high-K calc-alkaline peraluminous granite. The typical rock samples are enriched in Rb, Th, K and light rare earth elements, depleted in Sr, Ba, Nb, P and Ti, and these features are similar to that of the melt granite resulting from collision of plate margins. The JEu of the rocks falls the zone betw.en the crust granite and crust-mantle granite, and are close to that of the crust granite; （La/LU）N indicates the formation environment of granite is a continental margin setting. The Nb/Ta ratios are close to that of the average crust （10）; the Zr/Hf ratios of monzogranite are partly below.the mean mantle （34-60）, w.ile the Zr/Hf ratio of K-feldspar granite are close to the mean value in the crust. Comprehensive analyses show.that the granite in this area formed during the transition period betw.en tectonic collision and post-collision. During the plate collision and orogeny, the crust and mantle material w.re mixed physically, remelting into lava and then crystal fractionation, finally gave rise to the formation of the rock body in this area. This has close spatial and temporal relation w.th the molybdenum mineralization.

This paper describes a numerical simulation of the rigid rotation of the Moon in a relativis- tic framew.rk. Follow.ng a resolution passed by the International Astronomical Union （IAU） in 2000, w. construct a kinematieally non-rotating reference system named the Selenocentric Celestial Reference System （SCRS） and give the time transformation betw.en the Selenocentric Coordinate Time （TCS） and Barycentric Coordinate Time （TCB）. The post-New.onian equations of the Moon＇s rotation are w.itten in the SCRS, and they are integrated numerically. w. calculate the correction to the rotation of the Moon due to total relativistic torque w.ich includes post-New.onian and gravitomagnetic torques as w.ll as geodetic precession. w. find tw. dominant periods associated w.th this correction： 18.6 yr and 80.1 yr. In addition, the precession of the rotating axes caused by fourth-degree and fifth-degree harmonics of the Moon is also analyzed, and w. have found that the main periods of this precession are 27.3 d, 2.9 yr, 18.6 yr and 80.1 yr.

China＇s government statement recently reported the plan of constructing Xiong＇an New.Area, w.ich aims to phase out some extra capital functions from Beijing and to explore an innovative urban development mode w.th the priority in eco-environmental protection. The New.Area is located in the semi-arid North China Plain （NCP） and is home to NCP＇s largest natural freshw.ter w.tland, Baiyangdian Lake. A comprehensive realization of surface w.ter dynamics w.uld be crucial for policy-makers to outline a sustainable environment development strategy for New.Area. In this study, w. used a total of 245 time slices of cloud-free Landsat images to document the continuous changes of w.ter bodies w.thin Xiong＇an City dur- ing 1984-2016 and to provide detailed evidence of w.ter presence and persistency states and changes under the influences of climate change and human actions. Our results reveal that the New.Area w.ter body areas varied dramatically during the past 33 years, ranging from 0.44 km^2 in April 1988 to 317.85 km^2 in February 1989. The change of surface w.ter area w.s not characterized by a monotonically decreasing tendency. The evolution processes can be divided into four sub-stages： the first extreme desiccation in mid-1980s, the w.t stage w.th the most extensive inundation areas and strong inter-annual fluctuations from late-1988 to late 1999, another desiccation stage in early 2000s, and the overall recovering stage betw.en 2007 and 2016. w. also mapped the maximum w.ter inundation extents and frequencies of all-season, pre-w.t season （February-May） and post-w.t season （September-December） for the 33 years and different sub-periods. Although there is good agreement betw.en time series of surface w.ter area evolution in the New.Area and station-based precipitation and evaporation variations, multipie lines of evidences review.d in previous research indicate that the degraded Baiyangdian Lake w.s also tightly associated w.th human activities from various aspects, inc
