目的:观察高原军事训练期间等长运动对武警战士血管功能影响,为指导在高原的军事训练提供科学依据。方法:试验于2005/2006在青海(海拔约3000m,大气压力在60.49kPa)和天津(海拔约4m,大气压力约101.08kPa)完成。受试者为武警某部新兵连战士。将受试者分为3组,高原籍高原训练组(简称高原Ⅰ组,38人)、平原籍高原训练组(简称高原Ⅱ组,62人)、平原籍平原训练组(简称平原组,60人)。所有受试者进行12周训练,训练强度相同。训练前、训练第4,8,12周用XXG-E3型自动心血管功能诊断仪记录血管功能指标,每次在静态和50%单手最大握力状态下3min末同步纪录桡动脉脉搏图和肱动脉血压。结果:160名受试者均进入结果分析。①与等长运动前比较,3个组运动后平均收缩压升高[如第12周,平原组:(94.6±13.3)mmhg(1mmhg=0.133kPa)→(109.1±12.1)mmhg;高原Ⅰ组:(93.9±7.3)mmhg→(108.7±10.7)mmhg;高原Ⅱ组:(98.0±10.6)mmhg→(114.2±10.8)mmhg;P均hg→(87.5±11.1)mmhg;高原Ⅰ组:(73.1±7.1)mmhg→(89.2±11.7)mmhg;高原Ⅱ组(77.3±8.9)mmhg→(97.1±9.7)mmhg;P均hg→(98.3±11.4)mmhg;高原Ⅰ组:(83.5±7.0)mmhg→(99.0±11.0)mmhg;高原Ⅱ组(87.7±9.5)mmhg→(105.7±10.0)mmhg;P均hg→(34.2±9.3)mmhg,P0.05)。结论:①在低氧环境军事训练期间50%等长握力运动对体循环血管的功能影响较大,对肺循环血管的功能影响较小。②低氧军事训练对平原籍战士影响较大,但未见损伤心室和肺循环功能。

在磁云内部常常观测到反常高的重离子电离态,这些增加的重离子高价电离成分可以揭示其源区的温度特性.利用ACE卫星数据检查了1998年2月至2008年12月期间的74个磁云事件,发现14个磁云事件的内部具有明显的局部高温质子区.通过对这些高温区域内部质子温度与O^7/O^6比值和铁平均电离态áFe?进行相关性分析发现:9个磁云事件内部高温区域的质子温度和O^7/O^6比值或铁平均电离态áFe?具有一定的相关性,其余5个磁云事件内高温区域的质子温度与O^7/O^6比值和铁平均电离态都没有明显的相关性.这表明9个磁云事件内部的高温现象起源于太阳.

This report is a retrospective analysis of 27 patients who received Tacrolimus because of intol- erance or for refractoriness to Cyclosporin A (CyA) as prophylaxis against acute and chronic GvhD at a single institution. 9 patients were treated with Tacrolimus as acute GvhD developed despite optimal concentrations of CyA and 8 developed chronic GvhD despite continuation of CyA. 10 patients developed World health Organisation Score (WhO) grade 2–3 toxicity to CyA. Overall 21 of 27 patients responded to Tacrolimus. Patients who underwent reduced conditioning responded as well as those patients who un- derwent conventional conditioning regimens. Tacrolimus is well tolerated and e?ective and might be an alternative primary agent for prevention of GvhD. Its role in reduced conditioning regimens needs to be further explored.

We estimate oceanic excitations on polar motion using outputs from a data assimilating ocean general circulation model (OGCM) and satellite radar altimeter observations. The data include OGCM estimates of variations in ocean bottom pressure (OBP) and meridional and zonal velocities. Sea level anomalies from TOPEX/Poseidon (T/P) satellite altimeter measurements and steric sea surface height changes deduced from the model are also used to estimate OBP effects. The results are compared with observed polar excitations not accounted for by the atmosphere, and with results from previous studies. Estimated oceanic contributions from both the data-assimilating OGCM and T/P altimeter show considerably better agreement with polar motion observations compared with previous results based on non-data -assimilating and earlier T/P data. The improvement is particularly signitficant at intra-seasonal time scales. Both OBP and ocean current variations provide important contributions to seasonal polar motion. At intra-seasonal time scales, the oceans appear to be a dominant contributor to residual polar motion not accounted for by the atmosphere. The oceans also play an important role in seasonal excitation. Combined OBP and ocean current contributions explain much of the residual semiannual variability.

Autism spectrum disorder（ASD） is a developmental disorder that is characterized by symptoms of impaired social interactions, restricted interests and repetitive behaviors. Recent studies in humans and animal-models suggest that reduced GABAergic neurotransmission in the brain may underlie autism-related behavioral symptoms. It has been shown that propofol, a commonly used anesthetic, facilitates γ-aminobutyric acid-mediated inhibitory synaptic transmission. The present study investigated whether propofol improved autistic phenotypes in BTBR T + Itpr3 tf/j（BTBR） mice, a model of idiopathic autism. We found that i.p. injection of propofol in BTBR mice significantly improved aspects of social approach and repetitive behaviors without affecting reciprocal social interactions and without any detrimental effects in C57 BL/6 j mice. The ability of propofol to improve autistic phenotypes in BTBR mice through GABAergic neurotransmission suggests a potential pharmacological target for interventions to treat symptoms of autism.
