The frequency and intensity of extreme high temperature（EHT） in the northern hemisphere exhibit remarkable low-frequency（LF） variations in summer over the time period 1951-2017. Seven hotspots featuring both a high occurrence of EHT and large LF variations in EHT were identified in the northern hemisphere. The probability density functions show that the higher probabilities of the occurrence of EHT over these hotspots in recent decades are consistent with the shift in the mean temperature and an increased variance in the daily mean temperature. The common features of the LF variation in EHT frequency over all domains are a remarkable increasing trend and an evident decadal variations（DV）. The DV component makes the main contribution to the large LF variations. Further analysis shows that the DV over the six hotspots are the footprints of two dominant natural internal signals: the Atlantic Multi-decadal Oscillation（AMO） and the Inter-decadal Pacific Oscillation（IPO）. The coherent variation in temperature over western North America-Mexico, eastern Siberia, Europe, the Mongolian Plateau and southeastern China is significantly influenced by the AMO. The AMO contributes to the variations in temperature over the first four hotspots via its associated barotropic circum-global teleconnection, which imposes a striking anomalous pressure over these regions. The IPO governs the DV in temperature over the Indo-China Peninsula through an anomalous Walker circulation driven by the IPO-associated sea surface temperatures in the tropical Indian Ocean. The inconsistency between the in situ observations and the reanalysis datasets causes the uncertainty in the physical linkage between the natural internal variability and variations in EHT over southeastern China and the Indo-China Peninsula. This implies that natural internal forcing plays an important role in making hotspots more vulnerable to EHT.

Using the daily records derived from the synoptic weather stations and the NCEP/NCAR and ERA-Interim reanalysis data, the variability of the winter haze pollutions(indicated by the mean visibility and number of hazy days) in Beijing-Tianjin-Hebei(BTH) region during the period 1981 to 2015 and its relationship to the atmospheric circulations in middle-high latitude were analyzed in this study. The winter haze pollution in BTH had distinct inter-annual and inter-decadal variabilities without a significant long-term trend. According to the spatial distribution of correlation coefficients, six atmospheric circulation indices(I1 to I6) were defined from the key areas in sea level pressure(SLP), zonal and meridional winds at 850 h Pa(U850, V850), geopotential height field at 500 h Pa(H500), zonal wind at 200 h Pa(U200), and air temperature at 200 h Pa(T200), respectively. All of the six indices have significant and stable correlations with the winter visibility and number of hazy days in BTH. In the raw(unfiltered) correlations, the correlation coefficients between the six indices and the winter visibility(number of hazy days) varied from 0.57(0.47) to 0.76(0.6) with an average of 0.65(0.54);in the high-frequency(<10 yr) correlations, the coefficients varied from 0.62(0.58) to 0.8(0.69) with an average of 0.69(0.64). The six circulation indices together can explain 77.7%(78.7%) and 61.7%(69.1%) variances of the winter visibility and number of hazy days in the year-to-year(inter-annual) variability, srespectively. The increase of Ic(a comprehensive index derived from the six individual circulation indices) can cause a shallowing of the East Asian trough at the middle troposphereand a weakening of the Siberian high pressure field at sea level, and then accompanied by a reduction(increase) of horizontal advection and vertical convection(relative humidity) in the lowest troposphere and a reduced boundary layer height in BTH and its neighboring areas, which are favorable for t

背景脑脊液（cerebrospinalfluid，CSF）运动是影响等比重蛛网膜下隙麻醉药椎管内扩散的重要因素。由于各自特性的不同，麻醉前给予晶体或胶体负荷液对CSF脉冲式运动的影响不完全相同。因此，本研究观察了麻醉前预充晶体或胶体负荷液是否对CSF动力学（脉冲式运动）引起的等比重蛛网膜下隙麻醉药椎管内扩散有不同影响。方法等比重蛛网膜下隙麻醉药的临床研究中，患者随机分为两组：晶体液负荷组（η=30）及胶体液负荷组（η=30）。等比重蛛网膜下隙麻醉药为0．5％丁卡因。同时．通过MRI对23名健康志愿者讲行研究．分别观察给予品体及及胶体负荷液0、30分钟、60分钟后．CSF在L2-3节殿强中脑水管中部的运动。结果临床研究中，与胶体负荷液组（13．9±7．0分钟）相比，晶体负荷液组（27．1±17．8分钟）达感觉阻滞峰值时间明显延长（P〈0．01）。15分钟及20分钟时，晶体负荷液组平均感觉阻滞平面（15分钟：T10；20分钟：T9．5）显著低于胶体负荷液组（15分钟：T8；20分钟：T7）（P〈0．05）。MRI志愿者研究中，晶体负荷液组在30分钟时，直接来自头侧的CSF脉冲式运动在L2—3节段降低，而胶体负荷液组未出现显著变化。与基础值（448μl/min）相比，晶体负荷液组30分钟时CSF生成速度显著增加（637μl/min，P〈0．05），而在60分钟时轻微下降（609μl/min）。与基础值相比，胶体负荷液组30分钟及60分钟时CSF生成率没有统计学差异（基础值：464μl/min；30分钟：512μl/min；60分钟：542μl/min）。结论麻醉前给予胶体负荷液与无液体预充情形类似，而给予晶体负荷液，由于CSF生成增加，减弱了CSF脉冲式运动，进而延长等比重蛛网膜下隙麻醉药椎管内阻滞的感觉阻滞峰值时间。
