Orthotopic liver transplantation ( OLT) has evolved over the last forty years from an experimental endeavor to standard of care therapy for many patients with end stage hepatic disease. Many technical advances have contributed to the current success of OLT, but surgical complications, especially involving the biliary reconstruction, remain a morbid problem. Biliary complications after OLT include leaks and strictures. Strictures may be anastoinotic or intrahepatic and diffuse, as seen in cases of hepatic artery thrombosis. Current efforts to expand the limited donor pool include the use of non-heart beating donors. The organ procurement process in these donors entails an increased period of warm ischemia and results with non-heart beating donor grafts have been mixed. It is now appreciated that there is an increased incidence of subsequent diffuse biliary stricturing or ' ischemic cholangiopathy' in recipients of these organs. Animal models of this phenomenon and potential therapeutic strategies targeted at ischemic cholangiopathy are being developed with potential applicability to non-heart beating donation and will be the focus of this review.

The transiting exoplanet system HAT-P-24 was observed by using CCD cameras at Yunnan Observatory and Hokoon Astronomical Centre, China in 2010 and 2012. In order to enhance the signal to noise ratio of transit events, the observed data are corrected for systematic errors according to Collier cameron et al.＇s coarse de- correlation and Tamuz et al.＇s SYSREM algorithms. Three new complete transit light curves are analyzed by means of the Markov chain Monte Carlo technique, and the new physical parameters of the system are derived. They are consistent with the old ones from the discovered paper except for a new larger radius Rp = 1.364 Rj of HAT- P-24b, which confirms its inflated nature. By combining the five available epochs of mid-transit derived from complete transit light curves, the orbital period of HAT-P- 24b is refined to P = 3.3552479 d and no obvious transit timing variation signal can be found from these five transit events during 2010-2012.

We report new photometric observations of the transiting exoplanetary system WASP-32 made by using CCD cameras at Yunnan Observatories and Ho Koon Nature Education cum Astronomical Centre, China from 2010 to 2012. Following our usual procedure, the observed data are corrected for systematic errors according to the coarse decorrelation and SYSREM algorithms so as to enhance the signal of the transit events. Combined with radial velocity data presented in the literature, our newly observed data and earlier photometric data in the literature are simultaneously analyzed to derive the physical parameters describing the system by employing the Markov chain Monte Carlo technique. The derived parameters are consistent with the result published in the original paper about WASP-32b, but the uncertainties of the new parameters are smaller than those in the original paper. Moreover, our modeling result supports a circular orbit for WASP-32b. Through the analysis of all available mid-transit times, we have refined the orbital period of WASP-32b; no evident transit timing variation is found in these transit events.

利用云南天文台1 m望远镜以及丽江天文观测站2.4 m望远镜,分别在2009年和2012年对凌食太阳系外行星系统HAT-P-8进行了测光观测.为了提高凌食信号的信噪比,使用coarse de-correlation和SyeRem两种方法对测光数据中的系统误差进行了改正.应用MCMC(Markov Chain Monte Carlo)方法对3组数据进行同时分析求解获得了HAT-P-8系统新的物理参数.得到HAT-P-8b的半径为Rp=1.28 R_J(R_J为木星半径),这比该行星发现时Latham等人给出的数值要小,而与最近Mancini等人所得的结果一致.通过线性拟合23个慎重挑选的凌食中心时刻,得到HAT-P-8b新的轨道周期P=3.0763461±0.0000021 d,并且从(O-G)(观测值减计算值)分析中没有发现显著的TTV(Transit Timing Variation)信号.

To assist with the commissioning [1] of the Five-hundredmeter Aperture Spherical radio Telescope (FAST), we performed a pulsar search, with the primary goal of developing and testing the pulsar data acquisition and processing pipelines. We tested and used three pipelines, two (Pl and P2 hereafter) searched for the periodic signature of pulsars whereas the other one was used to search for bright single pulses (P3 hereafter).
