目的:观察针刺对失眠大鼠自发活动近日节律周期、丘脑网状核(TRN)内γ-氨基丁酸(GABA)能神经元、神经元上α7烟碱型乙酰胆碱受体(α7-nAChRs)和神经元突触可塑性的影响,探讨针刺治疗失眠的中枢调节机制。方法:将24只SPF级雄性SD大鼠随机分为空白组、模型组、针刺组,每组8只,采用对氯苯丙氨酸(PCPA)腹腔注射法建立失眠大鼠模型。针刺组于每日ZT授时因子时间(ZT4)(11:00)针刺单侧内关、足三里,每日1次,每次15 min,每5分钟行平补平泻的捻转手法1 min,共5 d。观察大鼠24 h自发活动昼夜节律周期及TRN内小清蛋白阳性神经元(PV)/α7-nAChRs、PV/突触后致密蛋白-95(PSD-95)的共表达情况。结果:造模后,模型组及针刺组自发活动近日节律周期显著缩短(P<0.01,P<0.05);针刺治疗后,针刺组自发活动近日节律周期延长,恢复至正常状态(P<0.05)。免疫荧光结果显示,模型组TRN内PV/α7-nAChRs、PV/PSD-95共表达水平均显著降低(P<0.01,P<0.05);针刺组TRN内PV/α7-nAChRs、PV/PSD-95的共表达水平均显著增加(P<0.05)。结论:针刺可能通过上调PV阳性神经元上α7-nAChRs的表达,激活TRN内GABA能神经元并改善神经元突触可塑性,恢复失眠大鼠自发活动近日节律周期,从而发挥治疗失眠的作用。

Recently, kilometer-scale Martian ionospheric irregularities have been measured by the Mars Atmosphere and Volatile EvolutioN(MAVEN) mission(Fowler et al., 2020). In this study, we carried out a simulation of these irregularities, assuming a uniform Martian zonal neutral wind and a cosinusoidal perturbation of the plasma density as the seeding source. Results show that a vertical electric field shear could be induced by such a plasma density perturbation. We find that the vertical electric field shear causes a velocity shear of the plasma between the topside and bottomside ionosphere, which in turn is able to produce kilometer-scale ionospheric irregularities — irregularities of a smaller scale than were seen in previous simulations(Jiang CH et al., 2021). These kilometer-scale variations with altitude, in plasma density and magnetic field profiles, are comparable to the MAVEN observations.

The pre-earthquake ionospheric anomalies in Wenchuan,China(21°-41°N,93°-113°E)are studied and analyzed using the summer nighttime data from 2005 to 2008 measured by DEMETER(Detection of Electro-Magnetic Emission Transmitted from Earthquake Regions)satellite detectors ICE(Internet Communications Engine),IAP(In Application Programming),and ISL(Interior Switching Link).In this paper,we take the 12 May 2008 Wenchuan earthquake as an example,use the spatial gridding method to construct the background field over the epicenter,analyze the background characteristics of very low frequency(VLF)electric field components,low-energy particle parameters,and plasma parameters,and define the perturbation intensity index of each parameter before the earthquake to extract each parameter anomaly in both space and time *** results show that the background values of some ionospheric parameters in the Wenchuan area are related to spatial ***,anomalous enhancement of low-frequency electric field power spectral density,H+concentration,He+concentration and ion concentration with different intensities and anomalous weakening of ion temperature were extracted in the fifteen days before the Wenchuan *** filtering the data to exclude external interference,such as solar activity,this paper concludes that there is some connection between these anomalies and the Wenchuan earthquake.

为了更好地探究我国城市地区大气污染问题,2019年10月15—2020年3月1日在山西省运城市采用四通道大气颗粒物采样仪每23 h进行1次细颗粒物(PM_(2.5))样品采集,分析了样品中有机碳(OC)、元素碳(EC)、水溶性有机碳(WSOC)、水溶性离子的浓度,并对比分析了甲醇提取液和水提取液的紫外-可见吸光特性.结果显示,采样期间PM_(2.5)质量浓度变化范围为6.21—325μg·m^(−3),其中有41 d达到《环境空气质量指数(AQI)技术规定(试行)》(HJ 633—2012)规定轻度污染及以上的标准,占总天数的64%,说明运城市冬季污染严重.其中,二次无机水溶性离子和有机质为PM_(2.5)的主要组成成分,分别占PM_(2.5)质量浓度的39.6%、29.7%(优良天),38.9%、30.8%(轻-中度污染),40.4%、29.1%(重度污染),38.9%、26.5%(严重污染).NO_(3)^(−)是含量最高的水溶性离子,并且4个时期NO_(3)^(−)/SO_(4)^(2−)的比值分别为2.15、2.11、2.31和1.93,说明机动车尾气排放的NO_(x)是污染的主要来源.对运城市水溶性棕碳(WSBrC)和甲醇溶性棕碳(MSBrC)在365 nm下不同时期Abs、AAE、MAE进行分析,发现所有时期甲醇提取液的有机组分光吸收效率均高于水提取液.对MSBrC与SOC和POC进行线性拟合,结果显示Abs_(365,M)与SOC(r=0.80)和POC(r=0.69)都具有较强相关性,表明其二次光化学反应为BrC主要来源.

The perfect sequences are so ideal that all out-of-phase autocorrelation coefficients are zero, and if the sequences are used as the coding modulating signal for the phase-modulated radar, there will be no interference of side lobes theoretically. However, it has been proved that there are no binary perfect sequences of period 4 〈 n ≤ 12100. Hence, the almost perfect sequences with all out-of-phase autocorrelation coefficients as zero except one are of great practice in engineering. Currently, the cyclic difference set is one of most effective tools to analyze the binary sequences with perfect periodic autocorrelation function. In this article, two characteristic formulas corresponding to the autocorrelation and symmetric structure of almost perfect sequences are calculated respectively. All almost perfect sequences with period n, which is a multiple of 4, can be figured out by the two formulas. Several almost perfect sequences with different periods have been hunted by the program based on the two formulas and then applied to the simulation program and practical application for ionospheric sounding.
