为探讨肝移植术后胆系并发症与移植术中胆道再建方式的关系,对100例次肝移植资料进行总结。70例次采用胆总管端端吻合法,30例次采用roux-Y法(胆-肠吻合法)。前者术后共10例次发生胆系并发症,后者15例次发生胆系并发症,两者比较,差异显著。25例次胆系并发症中,14例为胆道狭窄。认为胆道狭窄与手术技术有关,另外,胆道血供受损、供肝冷缺血时间过长、保存期间胆汁的直接毒性作用、ABO血型不符以及排斥等均可导致胆道狭窄。采取器官储存前清除残余胆汁、UW液胆系灌注保护、保护动脉血运、缩短或消除胆道热缺血时间、改进操作方法等,可降低胆道狭窄的发生率。

The use of in-seam waves for void detection in mines requires the capability of capturing high frequency signals over large distances. For instance, the Airy phase of Love waves which are used for void detection in coal mines ranges from several hundred to over one thousand Hertz and the expected travel distance of these signals is at least 90 m （equivalent to a detection distance of 45 m） for the technique to be considered practical. In order to obtain high quality and broadband signals, sensors are conventionally grouted at the bottom of boreholes so that the attenuation due to the fractured surface is minimized and the coupling effect is improved. However, to be economically feasible, the expensive and high sensitive sensors must be retrievable so that they can be used repeatedly at the same or other locations. Because of these concerns, a retrievable sensor installation technique was developed. This paper provides a detailed review of the technique as well as a brief discussion of its applications. The technique is simple and reliable for both installation and retrieval operations and can be used for boreholes oriented in any directions. The technique has been demonstrated in over 200 sensor installation/retrieval operations under various borebole conditions, including bituminous coal, anthracite coal, shale, sandstone and trona. With this technique, we were able to detect the high frequency signals required for our projects. For instance, the signals used at a trona mine for void detection have a typical frequency of 5 kHz with the travel distance of 150-200 m. The results of these operations have shown that sensors installed in the prescribed manner exhibit predictable, consistent, and repeatable performance. The technique also provides an economical and reliable means for many other field seismic monitoring applications where high quality and broadband signals are essential, such as microseismic monitoring and geotomography studies.

Ecosystems in Mediterranean climate regions are projected to undergo considerable changes as a result of shifting climate, including from extreme drought and heat events. A severe and sudden dieback event, occurring in regionally significant Eucalyptus gomphocephala woodland in Western Australia, coincided with extreme drought and heat conditions in early 2011. Using a combination of remote sensing and field- based approaches, we characterized the extent and severity of canopy dieback following the event, as well as highlighted potential predisposing site factors. An estimated 500 ha of woodland was severely affected between February and March 2011. Tree foliage rapidly discolored and died over this period. In the af-fected portion of the woodland, approximately 90% of trees greater than 20 cm DBH were impacted, while in the adjacent unaffected woodland 6% showed signs of damage. Tree density in the unaffected area had approximately 4.5 times more trees than the affected woodland. Precipitation drainage patterns are thought to explain the difference between affected and unaffected woodland. Dropping groundwater levels, a relatively shallow soil profile, and extreme drought and heat in 2010-2011 are thought to predispose water-shedding sites to drought-triggered canopy dieback during extended periods of dryness. Tracking forest health changes in response to severe disturbance is an important key to deciphering past and future vegetation change.

目前古代淀粉粒鉴别的两种方法,即显微镜观察法和碘着色测试法,均不能确保鉴别的准确性。针对耐热性α-淀粉酶只对淀粉产生降解的特点,设计出古代淀粉粒鉴别的"耐热性α-淀粉酶降解法",并运用到考古样品中淀粉粒的分析和鉴定之中。本文详细介绍了耐热性α-淀粉酶降解法的原理和流程,并通过古代淀粉粒的鉴别实验,确定了该方法在确切鉴别考古样品中淀粉粒的实用性和有效性;同时现代大麦和莲藕淀粉粒的降解实验结果表明不同植物来源以及同种植物内部不同粒径的淀粉粒其降解速率存在明显差异,而古代淀粉粒在耐热性α-淀粉酶作用下出现的降解速率差异的现象,或可揭示古代淀粉粒的植物来源,甚至长期埋藏对其产生的影响。

分析了赛前情绪与运动成绩的关系。研究表明,赛前的自信心程度、梦境、焦虑水平、对操作表现和个人潜力的知觉等因素与运动成绩有关。用《心境状态量表》(POMS)和《8种状态问卷》(8SQ)进行测验,发现了不同水平运动员的不同的情绪模式。由于认知先于情绪,因此,调节情绪应首先从调节认知着手,建立积极的内部条件反射;同时,还应将认知-情绪-行为链式反应各环节作为不可分割的整体。
