| 1 | A study of soil organic carbon distribution and storage in the Northeast Plain of China显示文摘采用联合起来的土壤碳数量(USCA ) 途径,土壤碳存储基于在 20042006 进行的多种用途的地区性的 Geochemical 调查(MRGS ) 越过中国的东北平原被计算。结果显示在表层土(00.2 m ) 的器官的碳(SOC ) 存储,心土(01 m ) 和深土壤(01.8 m ) 是的土壤有 3327.8 t/km2, 12,904.7 t/km2 和 16,157.5 t/km2 的密度的 768.1 山, 2978.4 山和 3729.2 山分别地。而土壤碳密度从东北平原(辽宁)的南部的区域显示出一个清楚的增加趋势,这些价值以表层土特别地与国家一般水准一致,到中间(吉林)和北平原( Heilongjiang )碳密度,从 2284.2 增加了,到 3436.7 和 3861.5 t/km2 ,分别地。与在 19841986 从第二国家土壤调查获得的碳数据(SNSS ) 相比,从 MRGS 的表层土 SOC 存储值被发现由 320.59 山(29.4%) 减少了,与在 20 年的 16.0 山(l.73%) 的平均年度衰落。在平原的南部、中间、北的区域,分别地,土壤碳密度为整个平原与 1389.0 t/km2 的平均价值由 1060.6 t/km2, 1646.4 t/km2 和 1300.2 t/km2 减少了。这些调查结果显示在土壤碳密度的减少根据不同生态系统和陆地使用类型变化了。因此,土壤碳密度的比率被计算以便学习碳,并且进一步探索分发特征在生态系统之间的动态平衡,以及 SOC 的隐遁潜力。 | Xiaohuan Xi Zhongfang Yang Yujun Cui Shumei Sun Chengguang Yu Min Li | 2011 | Geoscience Frontiers2011，2，2： | 5 |
| 2 | Definition of the Quaternary Qiangtang Paleolake in Qinghai-Tibetan Plateau, China显示文摘Since the Quaternary, many lakes have been present in the Qinghai-Tibetan Plateau. As peculiar geological processes in the evolution of the uplifting of Qinghai-Tibetan Plateau, the distributions and evolutions of the Quaternary paleolakes in the Qinghai-Tibetan Plateau have been the focus of interest among the international geosciences circle. Comparisons of the newly obtained and existing data from field surveys, remote sensing images, characteristics of tectonic landforms and distribution of the lacustrine strata, the author have, for the first time, defined a large-sized Quaternary Qiangtang Paleolake. The paleolake starts from the east-westerly direction at Rutog in western Tibet, passing through Gêrzê, and finally ends at Nagqu in eastern Tibet. Its length is approximately 1,200 km; it is about 420 km at its widest point (north-southerly). The Paleolake forms an E-W (or NWW) ellipsoid with an estimated area of 354920 km2 . The Paleolake is bordered by the Mts. Gangdisê and Nyainqêntanglha to the south and the Karakorum Pass-Tozê Kangri-Zangbagangri-Tanggula Pass to the north. It generally appears as a basinal landform with low mountains and valleys in the central part (altitudes of 4400 m) and higher altitudes (5000 m) in the peripheries. The formation and development of the Paleolake was controlled by the nearly E-W trending structures. There are three east-westerly extending tectonic sutures inside the Paleolake area, from north to south: (1) the Shuanghu Suture; (2) the Bangong Co-Nujiang River Suture; (3) the Shiquanhe-Lhari Suture. These three sutures have generally controlled the spreading features of the Paleolake and act as the first grade lake-controlling structures. In the southern Paleolake basin, there are a series of south-northerly rift basins, which are controlled by the normal faults and exist as a series of south-northerly grabens and semi-graben faulted basins. The south-northerly rift zones have clearly exerted control over the south margin of the Paleolake as well as the distribution of the residual lake basins after the Paleolake's break up. They are the secondary lake-controlling tectonics. Discoveries of the lacustrine strata inside the Plateau, especially the successive discoveries of many high-stand lacustrine strata, are direct evidence supporting the existence of the paleolakes in the Plateau. The dating results of the lake-eroded travertine in the Dong Co in the hinterland of the Quaternary Qiangtang Paleolake have revealed that the lake-eroded travertine is of Late Pleistocene sediments. By considering the analysis of the lacustrine strata as well, the researchers have revealed that the Quaternary Qiangtang Paleolake begins its embryonic form in the Early Pleistocene, successively develops till the Middle Pleistocene, and reaches its full blossom in the middle stage of the Late Pleistocene; it further shrinks and separates by the end of the Late Pleistocene, and finally ceases its whole life as the paleolake. After the Holocene, the huge Late Pleistocene Qiangtang Paleolake no longer exists, leaving a series of widely distributed smaller lakes on the Qiangtang Plateau. These smaller, isolated water systems receive the Holocene lacustrine sediments. | SHAO Zhaogang MENG Xian'gang HAN Jian'en ZHU Dagang YANG Chaobin WANG Jin YU Jia WANG Yan HE Chengguang | 2013 | Acta Geologica Sinica(English Edition)2013，87，2： | 1 |
| 3 | Repurposing diacerein to suppress colorectal cancer growth by inhibiting the DCLK1/STAT3 signaling pathway显示文摘Double cortin-like kinase 1(DCLK1)exhibits high expression levels across various cancers,notably in human colorectal cancer(CRC).Diacerein,a clinically approved interleukin(IL)-1βinhibitor for osteoarthritis treatment,was evaluated for its impact on CRC proliferation and migration,alongside its underlying mechanisms,through both in vitro and in vivo analyses.The study employed MTT assay,colony formation,wound healing,transwell assays,flow cytometry,and Hoechst 33342 staining to assess cell proliferation,migration,and apoptosis.Additionally,proteome microarray assay and western blotting analyses were conducted to elucidate diacerein’s specific mechanism of action.Our findings indicate that diacerein significantly inhibits DCLK1-dependent CRC growth in vitro and in vivo.Through high-throughput proteomics microarray and molecular docking studies,we identified that diacerein directly interacts with DCLK1.Mechanistically,the suppression of p-STAT3 expression following DCLK1 inhibition by diacerein or specific DCLK1 siRNA was observed.Furthermore,diacerein effectively disrupted the DCLK1/STAT3 signaling pathway and its downstream targets,including MCL-1,VEGF,and survivin,thereby inhibiting CRC progression in a mouse model,thereby inhibiting CRC progression in a mouse model. | YE Qiaobei ZHU Yu SHI Meng LV Linxi GONG Yuyan ZHANG Luyao YANG Lehe ZHAO Haiyang ZHAO Chengguang XU Huanhai | 2024 | Chinese Journal of Natural Medicines2024，22，4： | 0 |
| 4 | Design of Wireless Transmission System for Shallow Seismograph Based on 433 M Module显示文摘Because of its portability,the non-cable seismograph has become the future development trend of geophysical instruments.A new wireless data transmission device of 433 M module was proposed;a wireless network was built using the EL1663B_PA module of the SI4463 core,and through the SPI interface to modify the internal parameters.Data transmission used dual antenna mode,the main station as the center of the wireless network coverage up to 550 m or more.The wireless time synchronization system was designed to realize the wireless connection communication between the shallow seismograph and the sensor of each observation point.This program aimed to eliminate the necessary connecting cable and batteries between the conventional shallow seismograph and the detector,greatly reducing the weight of the equipment,and making the shallow seismograph truly low cost,lightweight,flexible and easy to operate and so on. | Li Liu Chengguang Zhang Taiquan Li Yu Liu Yan Jin Chao Zhou | 2019 | Open Journal of Yangtze Oil and Gas2019，4，2： | 0 |
