Gas chromatography-mass spectrometry was used to identify a series of n-alkanes in the sediments of a typical glacially eroded lake in the eastern Tibetan *** comparing the distribution patterns of n-alkanes in lake sediments,surface soils and cow manure,it was shown that n-C 27-n-C 33 alkanes in the soil ecosystem of Ximen Co are derived from vascular plant species and that the distribution pattern of n-C 27-n-C 33 alkanes remains unchanged during the feeding and digestion processes of *** relative percentage of C 27,C 29 and C 31 n-alkanes decreased from the bottom to the top of the sediment core showing a trend of degradation of higher plants in the Ximen Co lake region during the formation of the 44 cm core.210 Pb dating,combined with pre-existing AMS 14 C dating results showed that the depositional core reflects climatic and environmental variations since about 900 years before *** n-alkane indexes (ACL 27-33,P aq,P wax) are comparable with regional temperature variation,especially recording the Little Ice Age event (LIA).This study highlights that n-alkanes are valid proxies for paleo-climate and paleo-environment reconstruction,despite the same distribution patterns in n-alkane molecular fossils derived from a typical glacially eroded lake.

AIM:To determine the impact of a clinical pathway(CP) on acute pancreatitis(AP) treatment ***:A retrospective analysis of medical records was performed. We compared the results of AP treatment outcome over two time periods in our centre,before(2006-2007) and after(2010-2012) the implementation of a CP. The CP comprised the following indicators of quality:performance of all laboratory tests on admission(including lipids and carbohydrate deficient transferrin),determination of AP aetiology,abdomen ultrasound(US) within the first 24 h after admission,contrast-enhanced computed tomography of the abdomen in all cases of suspected pancreatic necrosis,appropriately selected and sufficiently used antibiotic therapy(if necessary),pain control,adequate hydration,control of haemodynamic parameters and transfer to the Intensive Care Unit(ICU)(if necessary),endoscopic retrograde cholangiopancreatography(ERCP) in biliary AP,surgical treatment(if necessary),and advice on outpatient follow-up after discharge. A comparison of the length of stay with that in other Slovenian hospitals was also ***:There were 139 patients treated in the three-year period after the introduction of a CP,of which 81(58.3%) were male and 58(41.7%) female. The patients' mean age was 59.6 ± 17.3 years. The most common aetiologies were alcoholism and gallstones(38.8% each),followed by unexplained(11.5%),drug-induced,hypertriglyceridemia,post ERCP(2.9% each) and tumours(2.2%). Antibiotic therapy was prescribed in 72(51.8%) patients. Abdominal US was performed in all patients within the first 24 h after admission. Thirty-two(23.0%) patients were treated in the ICU. Four patients died(2.9%). In comparison to 2006-2007,we found an increased number of alcoholic and biliary AP and an associateddecrease in the number of unexplained aetiology cases. The use of antibiotics also significantly decreased after the implementation of a CP(from 70.3% to 51.8%; P = 0.003). There was no statistically

利用气相色谱一质谱联用仪从青藏高原东部典型冰蚀湖湖泊沉积物中检测出正构烷烃系列分子化石，将其与湖区表层土壤及牛粪中正构烷烃的分布特征进行对比，认为冰蚀湖湖泊沉积物中C27-C33正构烷烃主要来自流域内土壤生态系统中的高等植物，且食草动物对高等植物的摄食消化过程并未显著改变C27-C33正构烷烃的分布特征．在0—44cm的湖泊沉积物岩芯中，陆生高等植被来源的正构烷烃相对含量从底部到顶部总体上呈现下降趋势，由此推测，湖区高等植被在0～44cm沉积时段内有逐渐退化的趋势．根据210Pb定年并结合已有的AMSH14^C年代，认为该沉积岩芯记录了希门错湖区过去近900a以来的气候和环境变化历史，其正构烷烃指标（ACL27-33，Paq以及Pwax）与区域温度记录具有一定的对应关系，特别是记录了相对寒冷的小冰期气候事件（LIA）．说明冰蚀湖湖泊沉积物中正构烷烃即使分布模式不变，其代用指标依然精细地记录了古气候、古环境变化信息．
