Cerebral ischemia was induced using photothrombosis 1.hour after intraperitoneal injection of the p38 mitogen-activated protein kinase （MAPK） inhibitor $B2.9063 into Swedish mutant amyloid precursor protein （APP/SWE） transgenic and non-transgenic mice. The number of surviving neurons in the penumbra was quantified using Nissl staining, and the activity of p38 MAPKs was measured by western blotting. The number of surviving neurons in the penumbra was significantly reduced in APP/SWE transgenic mice compared with non-transgenic controls 7 days after cerebral ischemia, but the activity of p38 MAPKs was significantly elevated compared with the non-ischemic hemisphere in the APP/SWE transgenic mice. SB2.9063 prevented these changes. The APP/SWE mutation exacerbated ischemic brain injury, and this could be alleviated by inhibiting p38 MAPK activity.

Ⅰ.INTRODUCTION The direct detection of dark matter particles,especially the weakly interacting massive particles(WIMPs),is being actively carried out by a couple of experiments worldwide[1..In recent years,the PandaX-Ⅱ experiment located in the china Jinping Underground Laboratory(CJPL)[1.3],which uses the {1. of dual phase liquid xenon time projection chambers(TPCs),has pushed the limits of the cross section between WIMPs and nucleons to a new level for most of the possible WIMP masses;other experiments of the same type are also being performed[4–1.].

Background: This study aimed to explore the characteristics of event-related potential induced by facial recognition in patients with first-episode schizophrenia and their siblings. Methods: In this case-control study, 30 first-episode schizophrenia patients, 2. siblings and 30 healthy controls were enrolled, who completed facial emotion recognition tasks from the Ekman Standard Faces Database, as an induction for evoked potentials. Evoked potential data were obtained using a 64-channel electroencephalography system. Average evoked potential waveforms were computed from epochs for each stimulus type. The amplitudes and latency of the event-related potentials P1.0, N1.0, N2.0 were investigated. Results: There were significant differences between the groups in amplitude of P1.0(F=1..52., P1., position(F=450.592. P1.;emotion(F= 1.2..467, P1., and intensity(F=1.37.1.9, P1.. Post hoc analysis showed significantly larger amplitudes in the schizophrenia patient group at O1. O2. P7, and P8. Conclusions: Patients with schizophrenia demonstrated abnormalities in the amplitude of P1.0. Our results provide evidence of dysfunctional event related potential patterns underlying facial affect processing in schizophrenia patients. P1.0 may be the characteristic index of schizophrenia.

The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the china Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a {1.8-ton fiducial mass and the signal region between 1.1. keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 1.^(-5) kg^(-1. d^(-1. keV^(-1.. The nuclear recoil background in the same region is {1.8 × 1.^(-7) kg^(-1. d^(-1. keV^(-1.. With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 1.^(-48) cm^{1.at a dark matter mass of 40 Ge V/c^{1.
