Allyl terminated polyether was used to improve the hydrophilicity of addition-cured room temperature vulcanization silicone rubber. With the increasing of the polyether, both the hydrophilicity and water absorbed of the vulcanizates were increased. The mechanical properties were also improved by adding the polyether. The result showed that 1.5wt% of the polyether provided the silicone rubber with proper hydrophilicity.

A model describing the propagation of optical waves in a hologram volume grating is studied. Then the effects of the change in the average permittivity and conductivity of a grating on diffraction efficiency are discussed. Finally a comparision of the results of this model with those by Solymar is made. The authors come to a conclusion that the effects of the change can be compensated.

Mounting evidence has shown that dyshomeostasis of the redox-active biometals such as Cuand Fe can lead to oxidative stress,which plays a key role in the neuropathology of Alzheimer's disease（AD）.Here we demonstrate that with the formation of Cu（Ⅱ）·Aβ1-40 complexes,copper markedly potentiatesthe neurotoxicity exhibited by β-amyloid peptide （Aβ）.A greater amount of hydrogen peroxide was releasedwhen Cu（Ⅱ）·Aβ1-40 complexes was added to the xanthine oxidase/xanthine system detected by potassiumiodide *** bound to Aβ1-40 was observed by electron paramagnetic resonance（EPR） *** dichroism （CD） studies indicated that copper chelation could cause a structuraltransition of Aβ.The addition of copper to Aβ introduced an increase on β-sheet as well as α-helix,whichmay be responsible for the aggregation of Aβ.We hypothesized that Aβ aggregation induced by copper maybe responsible for local injury in *** interaction between Cu2+and Aβ also provides a possible mechanismfor the enrichment of metal ions in amyloid plaques in the AD brain.

目的观察急性冠状动脉综合征(ACS)患者窦性心率震荡(HRT)的变化以及与冠状动脉病变的相关性。方法分别选择109例确诊为ACS患者(ACS组)和69例心脏正常者(对照组),行24 h动态心电图检查,并计算震荡初始值(TO)和震荡斜率(TS)及心率变异指标。同时检测临床资料和冠状动脉造影结果。并根据心肌酶以及心电图的变化对所有ACS患者分为急性心肌梗死(AMI,AMI亚组,51例)、不稳定性心绞痛(UAP,UAP亚组,58例)。比较各组HRT的差异,并根据冠状动脉造影结果分析HRT与Gensini评分的相关性。结果与对照组比较,ACS组TO明显升高(P<0.05),TS明显降低(P<0.01)。与UAP亚组比较,AMI亚组患者Gensini评分升高,TS明显降低(P<0.05,P<0.01)。Pearson相关分析显示,冠状动脉病变程度与TO呈正相关(r=0.23,P<0.05),与TS呈负相关(r=-0.46,P<0.01)。结论 ACS患者HRT现象明显受损,提示ACS患者的心脏自主神经调节功能下降,并且反映冠状动脉病变程度。

The dominant annual cycle of sea surface temperature(SST)in the tropical Pacific exhibits an antisymmetric mode,which explains 83.4%total variance,and serves as a background of El Niño-Southern Oscillation(ENSO).However,there is no consensus yet on its anomalous impacts on the phase and amplitude of *** on data during 1982-2022,results show that anomalies of the antisymmetric mode can affect the evolution of ENSO on the interannual scale via Bjerknes feedback,in which the positive(negative)phase of the antisymmetric mode can strengthen El Niño(La Niña)in boreal winter via an earlier(delayed)seasonal cycle transition and larger(smaller)annual *** magnitude of the SST anomalies in the equatorial eastern Pacific can reach more than±0.3◦C,regulated by the changes in the antisymmetric mode based on random sensitivity *** reveal the spatial pattern of the annual cycle associated with the seasonal phase-locking of ENSO evolution and provide new insight into the impact of the annual cycle of background SST on ENSO,which possibly carries important implications for forecasting ENSO.

目的研究急性冠状动脉综合征（ACS）患者窦性心率震荡（HRT）现象的变化及与左心室收缩功能的关系。方法103例ACS患者和62例健康者行24h动态心电图检查，根据心电图检查结果计算HRT指标：震荡初始值（TO）、震荡斜率（Ts）、心率变异（HRV）和全部窦性心搏RR问期的标准差（SDNN）。测量左心室射血分数（***）和左心室舒张末期直径（LVEDD）。根据心肌酶及心电图的变化将ACS患者分为急性心肌梗死、不稳定心绞痛两个亚组。比较ACS组与对照组及ACS各亚组各变量的差异，分析HRT与LVEF及LVEDD的相关性。结果（1）ACS组TO高于对照组（0．17±1．40）％与（一0．26±0．99）％，差异有统计学意义（P〈0．05）；TS低于对照组（RR问期分别为（0．88±2．51）ms与（2．60±2．76）ms，差异有统计学意义（P％0．01）]。（2）ACS患者两亚组比较，TS、LVEF、LVEDD差异有统计学意义（均P％0．01）。（3）LVEF与TS呈正相关（r=0．21，P〈0．05）；与TO负相关（r=-0．26，P〈0．05）。结论ACS患者窦性HRT减弱，提示ACS患者的心脏自主神经调节功能下降，HRT可作为一个评价左心室功能和预后的指标。
