青藏高原东缘北川和彭灌断层的活动构造

青藏高原东缘地区地形陡峭、起伏大,经历了新生代的快速冷却和剥蚀,却没有显示出该前陆盆地产生过大量级地壳缩短或调解过程的证据。我们通过应用各种地貌观测结果对平行于该高原边缘的几条大断层的运动和滑动速率进行约束,来论述这一矛盾。北川和彭灌断层主要是右旋滑动的活动构造,沿该高原边缘可连续追踪达200km。这两条断层都断错了河流填充阶地,得到的宇宙成因核素10Be经继承校正后,暴露物的年龄少于15ka,说明了晚更新世的活动。彭灌断层沿走向的两个地点在全新世看来活动过。两条断层晚第四纪的视下落速率沿走向是变化的,但一般都小于1mm/a。走滑位移的速率很可能要高出几倍,可能约为1～10mm/a,但仍旧约束不好。四川盆地西缘特别是山前带,在晚第四纪也发生了褶皱和右旋走滑活动。这些观测证明了该高原东缘形成和保持的模式,没有发生大的上地壳缩短。这些也表明,与青藏高原东缘平行的断层的活动可能预示着人口密集的四川盆地存在很大的地震危险性。

Effect of a hydrogymnastics program on the serum levels of high-sensitivity C-reactive protein amongst elderly women

中国毒理学会第三届全国学术会议

作者： l.R.Ferguson Discipline of nutrition and ACSRC The University of AucklandFaculty of Medical and Health SciencesAucklandNew Zealand

＜正＞ With the exception of tobacco consumption, diet is probably themost important factor in the etiology of human cancer, responsiblefor around one third of all cases. Despite strenuous attempts in i-dentification, no single causal factor stands out. However, car-cinogens may be introduced through preservation methods （n-ni-troso compounds）, high temperature cooking （heterocyclic aminesand polycyclic aromatic hydrocarbons） and spoilage （mycotoxins）.

The aim of this study was to evaluate the effect of a hydrogymnastics training program on highsensitivity C-reactive protein in elderly women. The subjects were randomly divided into the experimental group who participates in the hydrogymnastics training program and the control group who was not involved in the training and remained sedentary. The serum levels of highsensitivity C-reactive protein were determined by immunoturbidimetry using C-reactive protein (CRP), the training protocol consisted of hydrogymnastics sessions 5 times per week during 12 weeks of intervention, executed in a pool of 1.3 meters divided into three phases: a 10-minute warm-up, 30 minutes of aerobic exercise at 50%-60% of maximum heart rate (monitored by heart rate monitor) and a 10-minute cool down. As a statistical method to compare the results between groups of variables pre and post training, the analysis of variance (AnOVA) mixed 2 × 2 (group × measurement) test was done using SPSS version 17. The founds showed significant changes in the level of high-sensitivity C-reactive protein, and a greater percentage decrease of hs-CRP (Δ%= -37%, p = 0.001) in the experimental group in relation to the control ***, it can be inferred that a hydrogymnastics program is effective in reducing the metabolic rate of high-sensitivity C-reactive protein amongst elderly women.
