Objective:In the present study,from the functional perspective,the effect of neonatal repeated sevoflurane anesthesia on the synaptic plasticity at juvenile and adult age was observed in the SD rat model. Also,the related mechanism was probed in depth. Methods:*** and estab{1.shing models for repeated inhaled anesthesia:32.healthy P7 Sprague-Dawley（SD） rats,weight 1.;9 g,female and male either,were assigned into experimental group（group Sev） and control group（group C）(n=1.). Each group was divided into 2.subgroups:juvenile group（P37） and adult group（P97）. During juvenile stage,group Sev inhaled 2.6% sevoflurane and carrier gas（1.L·min-1.Air+1.L·min-1.O2. for 2.h at day 7,1. and 2.1}repeatedly,while group C inhaled carrier gas merely in the same time points. 2. Electrophysiological experiment:On postnatal day 37（P37） and P97,8 rats were extracted from each groups respectively for electrophysiological recording in vivo.（1.The tip of recording electrode located in the pyramidal cell body layer of CA1.the bipolar stimulating electrode was inserted into the ipsilateral Schaffer collaterals.（2.A test stimulation with duration of 0.2.ms and intensity of 3;m A was given every 1. s to e{1.cit the adequate wave shape. 50% of intensity to e{1.cit maximum amp{1.tude of population spike was regarded as intensity of basic stimulation. The response to basic stimulation was recorded for 30 min stably.（3） 5 min power spectrum analysis was implemented before basal stimulation,before HFS and after the whole recording to maintain the similar anesthetic level of each sample in the experiment.（4）After 30 min steady basal stimulus,paired stimulation with different interstimulus interval of 2.,50,75,1.0,1.0,2.0 and 2.0 ms were implemented. High frequency stimulation（HFS） was performed and thereafter shifted into basal stimulation for subsequent 90 min recording.（5）The population spike amp{1.tude（PSA）,slope of field excitatory postsynaptic potential（f EPSP） and the response to paired stimu

The Active Particle-induced X-ray Spectrometer （APXS） is an important payload mounted on the yutu rover, which is part of the Chang＇e-3 mission. The sci- entific objective of APXS is to perform in-situ analysis of the chemical composition of lunar soil and rock samples. The radioactive sources, 55Fe and 109Cd, decay and produce a-particles and X-rays. When X-rays and a-particles interact with atoms in the surface material, they knock electrons out of their orbits, which release energy by emitting X-rays that can be measured by a silicon drift detector （SDD）. The elements and their concentrations can be deter{2.ed by analyzing their peak energies and in- tensities. APXS has analyzed both the calibration target and lunar soil once during the first lunar day and again during the second lunar day. The total detection time lasted about 2.6 {2. and more than 2.00 frames of data records have been acquired. APXS has three operating modes： calibration mode, distance sensing mode and detection mode. In detection mode, work distance can be calculated from the X-ray counting rate collected by SDD. Correction for the effect of temperature has been performed to convert the channel number for each spectrum to X-ray energy. Dead time correction is used to eli{2.ate the systematic error in quantifying the activity of an X-ray pulse in a sample and derive the real count rate. We report APXS data and initial results during the first and second lunar days for the yutu rover. In this study, we analyze the data from the calibration target and lunar soil on the first lunar day. Seven major elements, including Mg, A1, Si, K, Ca, Ti and Fe, have been identified. Comparing the peak areas and ratios of calibration basalt and lunar soil the {12. site was found to be depleted in K, and have lower Mg and A1 but higher Ca, Ti, and Fe. In the future, we will obtain the elemental concentrations of lunar soil at the Chang＇e-3 {12. site using APXS data.

像木星和土星这样的冷巨行星对类地行星的形成和宜居性起到了关键作用,因此,对像太阳系这样具有多个冷巨行星的系统的搜寻具有重要意义.Kepler以及TESS (Transiting Exoplanet Survey Satellite)太空望远镜成功地通过凌星的方法发现了大量短周期行星,然而这些巡天项目的观测基线不足以发现更长周期的行星.为此,天语计划将部署两台1.望远镜(天语一号和天语二号),用于结合天语和其他计划的数据通过凌星法来发现冷巨行星及其他行星,并最终发现类太阳系.天语一号具有约1.平方度的视场以及高速CMOS (complementary metal-o{1.de-semiconductor)科学相机,将对超过1.00万颗恒星每小时进行一次高精度测光采样,并通过天语二号的多波段测光、光谱仪以及高分辨率成像对天语一号发现的候选行星进行确认.天语望远镜将放置于海拔约4000m的中国青海冷湖,是目前中国境内最好观测台址之一.天语对亮于1.等星的测光精度为0.1.,对亮于1.等星的测光精度优于1.,天语预计在5yr内将在类太阳周期发现超过300颗凌星行星,其中包括约1.颗冷巨行星.基于系统轨道共面以及孪生地球发生率为1.%的假设,天语预计将发现1.2.类太阳系,并可被未来的地球2.0计划所证实.此外,天语还将通过多种巡天观测模式测量从亚秒到周时标的光变,探测不同时标的时域现象,包括超新星早期光变、稀有变星和双星、潮汐瓦解事件、Be星、彗星活动以及系外小行星等.这些发现不仅将深化我们对宇宙的理解,还将为公众科学和科普提供重要平台.
