OBJECTIVE: To investigate neuropsychological features of post-stroke cognitive impairment with no dementia(PSCIND) patients with different Traditional Chinese Medicine(TCM) ***: We recruited 50 patients with PSCIND between April 2012 and March 2013. Patients were divided into different groups according to TCM classifications. Patients were assessed using neuropsychological tests, including cognitive screening(mini-mental state examination), memory testing (auditory verbal learning test), executive/attention[shape trails test, stroop color-word test(SCWT),reading the mind in the eyes test, the digit ordering test-A(DOT-A), and symbol digit modalities test], language(action naming test, Boston naming test, famous face test, similarity test, and verbal fluency test), and visuospatial functioning [complex figure test(CFT)].RESULTS: We found no significant differences between patients with and without a diagnosis of turbid phlegm blocking the upper orifices on neuropsychological test performance. Patients diagnosed with upper hyperactivity of liver Yang syndrome scored significantly lower on the SCWT-C executive test and the CFT-delayed recall memory test. Patients with excess syndrome scored significantly lower on the SCWT-C executive test, and significantly higher on the DOT-A executive ***: Neuropsychological characteristics differ between PSCIND patients with different TCM classifications.

High pressure solidification rules of Al-Mg alloy needs to be discussed further for its wide range of application. Microstructures and phases of Al-25wt% Mg alloy solidified at 4 GPa were studied by optical microscope,X-ray diffractmeter,energy dispersive X-ray spectroscopy and transmission electron microscopy( TEM). The microstructure evolution mechanism of Al-25Mg alloy under high pressure was analyzed. The result shows that the alloy consists of α-Al phase and Al 3 Mg 2 phase under normal pressure. However,only Al 12 Mg 17 phase forms without Al 3 Mg 2 phase at 4 GPa. In addition,Mg concentration in α-Al phase increases and that of the lattice constant also increases. The α-Al dendrite presents the broken arms under normal pressure, after high pressure solidification,the morphology of the dendrite tends to integrate and the size of the dendrite arms

Constructing and maintaining a stable terrestrial reference frame （TRF） is one of the key objectives of fundamental astronomy and geodesy. The datum realization for all the global TRF versions, such as ITRF2014 and its predecessor ITRF2008, assumes linear time evolution for transformation parameters and then imposes some conditions on these Helmert transformation parameters. In this paper, we investigate a new approach, which is based on weekly estimation of station positions and Helmert transformation parameters from a combination of the solutions of four space-geodetic techniques, i.e., Satellite Laser Ranging （SLR）, Very Long Baseline Interferometry （VLBI）, Global Positioning System （GPS） and Doppler Orbitography and Radiopositioning Integrated by Satellite （DORIS）. For this study, an interval of one week is chosen because the arc length of the SLR solutions is seven days. The major advantage of this weekly estimated reference frame is that both the non-linear station motions and the non-linear origin motion are implicitly taken into account. In order to study the non-linear behavior of station motions and physical parameters, ITRF2008 is used as a reference. As for datum definition of weekly reference frame, on one hand SLR is the unique technique to realize the origin and determine the scale together with VLBI, and on the other hand the orientation is realized via no net rotation with respect to ITRF2005 on a subset of core stations. Given the fact that without enough collocations an inter-technique combined TRF could not exist, the selection and relative weight of local ties surveyed at co-location sites are critical issues. To get stable results, we first assume that, if there were no events such as equipment changes between the measurement epoch of the local tie and that of the space- geodetic solution, the relative position between the two co-located stations should be invariant and this local tie could be used for computing the inter-technique combined ref

Four ＂picket fence＂ porphyrin atropisomers were respectively synthesized from the four corresponding atropisomers of meso-tetra（o-aminophenyl）porphyrin that had been chromatographed on a column eluted with petroleum ether and ethyl acetate. Results show that each atropisomer could be successfully synthesized by controlling the acylation temperature at 0 ℃. They were characterized by 1H NMR, HRMS, IR, UV-Vis and Langmuir-Blodgett（LB） film analyses. Although the results of HRMS, IR, UV-Vis analyses indicate there is no remarkable difference among the atropisomers, the results of the 1H NMR and the mean molecular areas obtained by LB film technique imply that the atropisomers are significantly discrepant. The former shows that the chemical shifts of the methyl and amide protons of each atropisomer are distinct, while the later presents that the different atropisomer molecules can occupy the different surface areas at the air/water interface.
