在板块重建过程中,大洋扩张、俯冲到陆陆碰撞等关键地质过程的起始或结束时间,经常缺少直接的证据来精确限定。在亚洲中西段的大陆形成演化过程中,发育在古生代-早中生代的古特提斯构造系统起到了至关重要的作用,但是其中的关键构造阶段的时间线却不甚清楚。本文选取了伊朗东北部古特提斯构造域中的Binalud山脉为研究对象,通过构造和碎屑锆石年代学相结合的手段开展详细研究,来恢复该地区的古特提斯构造演化。Binalud山脉强烈的挤压构造揭示了三叠纪的碰撞过程;而对于连续的俯冲碰撞历史则通过对该地区古生代-中生代地层的碎屑锆石研究揭示。我们主要得到以下主要结论:

Journal of Diabetes Mellitus 2013年第3期3卷 134-138页

作者： allen mark Jacobs Dunlei Cheng Saint Louis University School of Medicine Saint Louis USA University of Texas School of Public Health Dallas USA

Objective: To study the effect of addition of Metanx?on burning parasthesias in patients with symptomatic diabetic neuropathy who had obtained only partial symptom resolution with pregabalin. Research design and methods: This was an open-label pilot study. There were 16 patients (7 males, 9 females) in the study group and 8 patients (3 males, 5 females) in the control group. A patient numeric rating scale (0 - 10) of neuropathy associated pain was obtained at baseline and at 20 weeks. The control group continued on a fixed dosage of pregabalin (Lyrica) without additional medication, while the study group was supplemented with Metanx?(L-methylfolate, methylcobalamin, and pyridoxal 5- phosphate), in addition to being continued on a fixed dosage of pregabalin. Results: After 20 weeks, patients in the study group experienced greater pain relief compared to the control group, (87.5% vs. 25% respectively, p = 0.005). The average pain score reduction after 20 weeks in the study group was 3 compared to0.25 inthe control group (p < 0.001). Conclusion: Our study suggested that addition of Metanx?may be used for the relief of pain in patients that have obtained only partial resolution of symptomatology from pregabalin.

The North Qilian orogen on the northeast margin of the Tibet plateau, records the significant tectonic evolution history of Proto-Tethys Ocean from its spreading, subduction to closure. However, the timing of subduction initiation, the polarity and the arc volcanic process of the Proto-Tethys Ocean remain controversial. In this contribution,
