| 1 | Late Cretaceous biota and the Cretaceous-Paleogene(K--Pg)Boundary in Jiayin of Heilongjiang,China显示文摘An international cooperative study of the Late Cretaceous biota and non-marine strata including the Cretaceous-Paleogene(K--Pg) boundary in Jiayin near the Heilongjiang River,China during 2002-2010,is summarized in this paper. The strata includes the Upper Cretaceous Yong'ancun-,Taipinglinchang-,Yuliang-zi-,and Furao formations,and the Paleocence Wuyun Formation consisting of Baoshantou Member and a Coalbearing Member. Seven palynological assemblages from Santonian to Paleocene are recognized,which is used for definition of the K--Pg boundary. Through the palynological analysis of three drilled boreholes (XHY-2005,2006,2008) in Xiaoheyan of western Jiayin,the K--Pg boundary is defined within 20. 00-20. 05 m in the borehole XHY-2006 (as a standard boundary) which is just between the top of Furao Formation (late Maasterichtian) and the base of Baishantou Member (early Danian) . These new research results are supported by paleo- magnetic,geochemical and other analyses,also. On the other hand,the presence of eight taxa of Maasterichtian dinosaurs (mostly hadrosaurids) have been recognized by the authors; and two mega-plant assemblages from the Yong'ancun Fm (Santonian) to Taipinglinchang Fm (Campanian) are confirmed. These research a-chievements indicate that the Upper Cretaceous-Paleocene in Jiayin can be well correlated to the strata in the neighboring Zeya-Bureja basin,Russia. The K--Pg boundary definited in Jiayin is the first well documented non-marine K--Pg boundary in China. Also the related paleoclimate,paleoenvironment and the mass extinctions in this area during the Cretaceous-Paleocene transition are also discussed. | Sun G. Akhmetiev M. Markevich V. Ashraf A. R.

| 5 | 输液方式行部分肠道营养治疗儿童活动性克罗恩病:一项随机对照试验显示文摘Background and aims: Total enteral nutrition (TEN) with a liquid formula can suppress gut inflammation and induce remission in active Crohn’s disease. The mechanism is obscure. Studies have suggested that long term nutritional supplementation with a liquid formula (partial enteral nutrition (PEN)) may also suppress inflammation and prevent relapse. The aim of this study was to compare PEN with conventional TEN in active Crohn’s disease. Patients and methods: Fifty children with a paediatric Crohn’s disease activity index (PCDAI) > 20 were randomly assigned to receive 50% (PEN) or 100% (TEN) of their energy requirement as elemental formula for six weeks. The PEN group was encouraged to eat an unrestricted dietwhile those receiving TEN were not allowed to eat. The primary outcome was achievement of remission (PCDAI < 10). Secondary analyses of changes in erythrocyte sedimentation rate (ESR), C reactive protein, albumin, and platelets were performed to look for evidence of anti-inflammatory effects. Results: Remission rate with PEN was lower than with TEN (15% v 42% ; p = 0.035). Although PCDAI fell in both groups (p = 0.001 for both), the reduction was greater with TEN (p = 0.005). Moreover, the fall in PCDAI with PEN was due to symptomatic and nutritional benefits. With both treatments there were significant improvements in relation to abdominal pain, “ sense of wellbeing', and nutritional status. However, only TEN led to a reduction in diarrhoea (p = 0.02), an increase in haemoglobin and albumin, and a fall in platelets and ESR. Conclusions: TEN suppresses inflammation in activeCrohn’s disease but PEN does not. This suggests that long term nutritional supplementation, although beneficial to some patients, is unlikely to suppress inflammation and so prevent disease relapse. | Johnson T. Macdonald S.

| 8 | Correlates of subjectively and objectively measured physical activity in young adolescents显示文摘背景:很多研究利用自我报告评价青少年个体活动水平,而不是通过客观测量。利用自我报告方式得到的结果与客观测量体力活动相比,可能产生并不存在的关联。本研究旨在探讨与体力活动相关的假设在主客观测量体力活动间的联系。方法:通过加速度计测量对被试青少年(共232人,其中男性101名,平均年龄12.3岁)进行至少4天体力活动检测,同时完成调查评估,包括中高强度体力活动(MVPA)、运动能力、参与度、享受度和自我效能感,并测量身高、体重和BMI。结果:用分层回归模型通过控制性别、种族和BMI的Z值,发现性别、BMI的Z值与客观测量得到的MVPA明显相关:同时,仅性别与客观测量的体力活动总量明显相关。相反,用单一模型衡量主观MVPA关系时发现,仅体力活动的享受度、自我效能感与自我报告的体力活动明显相关。结论:通过自我报告和使用加速度计的客观监测方法测量青少年MVPA,两者所得结果存在较大差异。今后研究若要确定与青少年MVPA相关的因素,应谨慎选择测量方式。 | Kelly Kavanaugh Justin B.
