164320例烧伤病人的分析显示文摘本文收集和分析了全军1980~1992年29个单位烧伤住院病人64320例,并与前阶段(1958~1979年)分析的16个单位48978例病人进行了对比。本阶段病人伤情虽较前阶段为重,但平均住院日明显缩短,特别有Ⅲ度者缩短达12d之多,总LA50(半数面积死亡率)及有Ⅲ度LA50分别由前阶段的75.93%和46.19%提高到96.99%和90.87%。治疗进步的主要原因,与本阶段广泛采用了早期切痂全覆盖植皮以及休克和感染的防治进步有关。另分析本阶段主要死亡原因为内脏功能不全(50.30%)、全身性感染(19.04%)和吸入性损伤(16.24%),三者占死亡总数的85%以上。为今后防治的重点。内脏功能不全中又以肺功能不全居首位,认为与吸入性损伤关系密切。Li Ao Huang Yaosheng Zhang Ning et al.(Third Military Medical College, Chongching 630038) 1995解放军医学杂志1995,20,1:29
2China's wetland change (1990-2000) determined by remote sensing显示文摘Two wetland maps for the entire China have been produced based on Landsat data acquired around 1990 and 2000. Wetlands in China have been divided into 3 broad categories with 15 sub-categories except rice fields. In 1990, the total wetland area in China was 355208 km2 whereas in 2000 it dropped to 304849 km2 with a net loss of 50360 km2. During an approximate 10-year period, inland wetland reduced from 318326 to 257922 km2, coastal wetland dropped from 14335 to 12015 km2, while artificial wetland increased from 22546 to 34911 km2. The greatest natural wetland loss occurred in Heilongjiang, Inner Mon- golia, and Jilin with a total loss of over 57000 km2 of wetland. In western China, over 13000 km2 of wetlands were newly formed in Xinjiang, Tibet, and Qinghai. About 12000 km2 of artificial wetlands were also added for fish farm and reservoir constructions. The newly formed wetlands in western China were caused primarily by climate warming over that region whereas the newly created artificial wetlands were caused by economic developments. China’s wetland loss is caused mainly by human activities.Peng Gong ZhenGuo Niu Xiao Cheng KuiYi Zhao DeMin Zhou JianHong Guo Lu Liang XiaoFeng Wang DanDan Li HuaBing Huang et al. 2010Science China Earth Sciences2010,53,7:28

4中日竞走运动员高原训练的生理机能及运动能力的研究显示文摘10名世居高原(2260米)的中国竞走运动员和10名居平原(10m)的日本竞走运动员在多巴(2366米),作4周高原训练。高原训练后期与前期、高原与平原相比,观察到有益的代偿性改变。如运动后的恢复心率(1分至1分10秒)下降加快(13次/分降至105次/分);在负荷心率相近条件下,步速加快(3.61m/s增至3.80m/s),无氧阈速度加快(中方,3.01增至3.22;日方,2.78增至3.30m/s);左室功能有改善(SV:日男由85.4→98.1ml;C1:中男由3.10→3.28L/m^2·min);乳酸—速度曲线右移(日男由7.2→5.4mM,中男由6.2→5.6mM);缓冲系统的能力有改善(女子:BE,—4.7→0.2mM;HCO_3,18.6→25.2mM);肺通气功能有所加强(MVV:中方,108.6→113.5L/min,日方,139.8→146.6L/min)。高原训练后,下平原比赛,中日各有8名队员提高了本人最好成绩。Li Hua, et al.

5Progress and records in the study of endogenetic mineralization during collisional orogenesis显示文摘To develop and perfect the theory of plate tectonics and regional metallogeny, metal-logenesis during collisional orogenesis should be thoroughly studied and will attract increasing at-tention of more and more scientists. This paper presents the main aspects of research and discus-sions on metallogenesis during collisional orogenesis after the development of plate tectonics, and accordingly divides the study history into two stages, i.e. the junior stage during 1971-1990 and the senior stage after 1990. Beginning with the negation of mineralization in the collision regime by Guild (1971), the focus of study was put on whether there occurred any mineralization during collisional orogenesis at the junior stage. At the senior stage, which is initiated by the advance of met-allogenic and petrogenic model for collisional orogenesis, scientists begin to pay their attention to the geodynamic mechanism of metallogenesis, spatial and temporal distribution of ore deposits, ore-forming fluidization, relationshipYanjing Chen Huayong Chen Yulin Liu Guangjun Guo Yong Lai Shan Qin Baoling Huang Zengjie Zheng Yinghui Sui Chao Li et al. 2000Chinese Science Bulletin2000,45,1:13
6Nerve Growth Factor Prevents the Apoptosis-associated Increase in Acetylcholinesterase Activity after Hydrogen Peroxide Treatment by Activating Akt显示文摘Acetylcholinesterase (疼痛) 被认为玩结果显示出的重要角色 duringapoptosis.Our 那 H_2O_2 导致了疼痛活动,功能的标记 inapoptosis,象 neuronal 一样 PC 12 房间的增加。谷胱甘肽,涉及细胞的氧化还原作用动态平衡,禁止了疼痛活动的增加,建议在这个过程的那个反应的氧种类(ROS ) 千盐湖钥匙角色。进一步的调查证明疼痛的举起在 Akt,从进 cytosol 的线粒体的细胞色素 c 的版本,和 caspase 家庭成员的激活的降级以后被观察。神经生长因素(NGF ) 什么时候是在场的,与 Akt 水平,疼痛的举起,细胞色素 c 散开,以及 apoptosis 的维护,显著地在对待 H_2O_2 的 PC12 细胞被稀释。然而, wortmannin, PI3K/Aktpathway 的一个禁止者,加速了 apoptosis 并且增加了疼痛活动。过去表示 ofconstitutively 激活 Akt,它是 NGF receptorTrkA,推迟的 mitochondrial 倒塌和疼痛活动的禁止的举起的一个下游的发信号元素。因此, NGF preventedapoptosis 和由激活 Akt 小径并且稳定线粒体的功能的疼痛活动的举起。Hua JIANG~(1,3) Jingya ZHANG~(1,3) Hui ZHU~(1,3) Hong LI~2 and Xuejun ZHANG~1 ~1Laboratory of Molecular Cell Biology,Institute of Biochemistry and Cell Biology,Shangha Institutes for Biological Sciences,Chinese Academy of Sciences,Shanghai 200031,China ~2DEFEMA,Faculté de Medecine et de Pharmacie,University of Rouen,Rouen 76821,France ~3Graduate school of the Chinese Academy of Sciences,Beijing 100080,China 2007Acta Biochimica et Biophysica Sinica2007,39,1:9
7Microelement analysis of source of raw materials of terracotta warriors and horses of Qin's Mausoleum in pits No.1 and No.2显示文摘In order to search for sources of the raw material of the Qin’s terracotta warriors and horses, we selected 20 samples of pottery warriors and pottery horses of the Qin’s Mausoleum from pit No. 1,19 samples of pottery warriors and brick from pit No. 2, 20 samples of clays near the Qin’s Mausoleum and 2 samples of Yaozhou porcelain bodies. The 32 kinds of element content of each sample were measured by neutron activation analysis (NAA). These data were analyzed by fuzzy cluster analysis, the trend cluster analysis diagram was obtained. The results showed that samples of terracotta warriors and horses from pits No.1 and No. 2 were closely related to the loam layer near Qin’s Mausoleum, but their relations with the loess layers were not so close, and they were out of all relation to Yaozhou porcelain bodies. Thus, it could be deduced that the Li Mountain clay may be considered as the original place of the raw materials of the terracotta warriors and horses, the kiln sites might be located nearby the Qin’sWeijuan Zhao Aijun Xu Rongwu Li Zhengyao Gao Guoxia Li Jianzhong Xie Guohe Han Songlin Feng Dongyu Fan Ying Zhang et al. 2002Chinese Science Bulletin2002,47,16:6

9上海医务人员中幽门螺杆菌感染的血清流行病学调查显示文摘本文对上海市16所大、中型医院的部分消化科医生、护士及医护人员1050人进行了血清HP抗体检测,结果提示:1.医务人员,特别是从事消化内镜工作的医生和护士是易受HP感染的高危人群。揭示HP通过口-口或粪-口途径传播,医务人员要加强自我防护。2.有消化不良症状者的HP感染率高于无症状者,提示HP感染与症状相关。3.家庭密切接触成员中有消化性溃疡病史者的HP感染率高于无溃疡病史者。Liu Wenzhong Xiao Shudong Li Rongrong,et al.(Shanghai Intitute of Digestive Disease) 1995中华消化杂志1995,15,S1:3
10An L-band HTS duplexer with improved performance显示文摘An L-band HTS duplexer with improved performance for communication applications has been developed.This is an improved version of the duplexer previously developed by our group.The duplexer was composed of a T-junction and two channels.Each channel has a 10-pole quasi-elliptic function bandpass HTS filter with a bandwidth of 27 MHz,and center frequencies at 1200 MHz and 1260 MHz.To achieve higher performance,especially a good balance between selectivity and flat group delay,the two pairs of transmission zeros from the two filters were reassigned so that one pair is used for high selectivity and the other for flat group delay.To reduce the influence of parasitical coupling,new coupling structures were developed in the simulation process.The duplexer was fabricated on a 2 inch diameter,0.5 mm thick LaAlO3 wafer with a double-sided YBCO film.The measured results showed a very high performance:a mid-band insertion loss of 0.2 dB,a return loss better than-14 dB,a shape factor better than 1.4:1,an out-of-band rejection of better than 70 dB in a wide frequency range up to 3 GHz and excellent isolation(higher than 80 dB) between the two channels.In addition,the frequency band 5 ns group delay variation is over 10.5 MHz(38.7% of 1 dB bandwidth).Jia Wang Qiang Zhang Bin Cui Jin Guo YongBo Bian XiaoFeng He ChunGuang Li XueQiang Zhang Hong Li WuXia Li et al. 2010Chinese Science Bulletin2010,55,31:2
11Nuclear transfer using nonquiescent adult fibroblasts from a bovine ear显示文摘The natural reproduction of mammal is sexual reproduction, which needs fertilization involving sperm and oocyte. Nuclear transfer provided an asexual reproduction method for mammal. Donor cells used in previous experiments of nuclear transfer were mostly from undif-ferentiated or non-terminally differentiated cells, such as embryonic or fetal cells. However, since Wilmut et al. obtained a viable lamb by transfer of an adult sheep somatic cell intoJilong Liu Minkang Wang Li Lian Jinsong Li Shaorong Gao Zhiming Han Qingyuan Sun Xiangfen Song Dongmei Zhang Yihai Li et al. 1999Chinese Science Bulletin1999,44,21:2
