目的:观察电针治疗对躯体形式障碍(SFD)患者睡眠脑电及事件相关电位(ERP)的影响。方法:选择75例SFD患者为电针组,予以电针神庭和百会治疗,每次30 min,每日1次,连续治疗6 d为1个疗程,疗程间休息1 d,共治疗4个疗程。治疗前采用躯体症状检查报告单对患者的主要症状进行调查。治疗前和治疗后进行睡眠脑电Quisi监测,检测ERP失匹配负波(MMN)和P300。对40名正常人进行相同的睡眠脑电Quisi监测和ERP检测,作为正常对照组数据。结果:研究过程中电针组13例患者因资料不全被剔除,最终有62例纳入统计分析。在62例SFD患者中,困扰患者的主要症状依次是认知功能障碍、睡眠障碍、呼吸系统、消化系统、五官及心血管系统症状。与正常对照组比较,治疗前电针组患者ERP的MMN及P300潜伏期延长,波幅下降,组间差异均有统计学差异(P0.05);Quisi指标中电针组的TST增加,RL延长,SL缩短,AT减少;睡眠结构的主要改变是S1占比减少,S2占比增加,SE提高,与本组治疗前差异均有统计学意义(P0.05)。除TST、RT、S1占比及SWS外,其他Quisi指标(包括RL、NRP、SL、AT、SE及S2占比)的组间差异均无统计学意义(P>0.05)。结论:SFD患者的临床症状表现多样,多数患者存在睡眠脑电及ERP异常;电针治疗可纠正SFD患者异常的睡眠脑电指标及ERP的MMN和P300。

目的分析子痫前期患者的肠道菌群特征。方法收集2020年7月至2022年7月在南昌大学第一附属医院接受治疗或住院的42例子痫前期患者(PE组)和20例正常孕妇(NP组)的粪便标本,通过16Sr RNA基因测序技术检测两组的肠道菌群,并分析肠道菌群特征。结果与NP组比较,PE组肠道微生物α多样性、β多样性降低(P<0.01)。在门水平上,两组粪便微生物主要由拟杆菌门、厚壁菌门、变形菌门、放线菌门和脱硫杆菌门等类别组成,其中拟杆菌门、厚壁菌门和变形菌门在肠道微生物群落中占据优势地位;在属水平上以拟杆菌属、普雷沃氏菌属、柔嫩梭菌属为优势菌属。结论PE患者较正常孕妇肠道菌群的多样性和丰富度降低,两者菌群结构存在差异。

In this investigation, basalt mineral fiber softening agent was prepared in order to obtain desirable flexible performance. Stability and physical chemistry natures of softening agent were evaluated by particle size distribution, dilution, storage and folding endurance etc. Constitutes of basalt and wood fibers were determined by energy dispersion analysis X-ray which served as an accessory of scanning electron microscopy (SEM-EDAX). Naturally degradable ecocomposite was prepared by basalt and wood fibers. The results of SEM observation illustrated that the wood and basalt fibers were blended uniformly. The impact factors of beating degree, content of wood fibers and adhesive etc. were discussed. The structure of the naturally degradable ecocomposite was contrasted with that of pure wood fibers and the cause of excellent filtration performance was analyzed. Compared with traditional methods, it was of saving wood resource, a large amount of water and reducing second pollution. As a consequence, the ecocomposite harmonized with environment and accorded with requirement of benignly friendly environment.

On the northern fringe of Mt. huangshan, many fiver terraces are developed at the junction between mountains and plains. The fiver terraces are most typical in the Jingxian Basin, anhui Province, where the Qingyijiang River, one of the longest tributaries of the lower Yangtze River, developed three staircase terraces. The topmost terrace （i.e., the T3 terrace） tread is 38 - 39 m above fiver level, and the top of the gravels is generally covered by 3 - 10.9 m of red clay deposits. Systematic magnetostratigraphy and electron spin resonance dating are used to research the timing of the establishment of the Qingyijiang River. The main results show that the topmost terrace developed no later than 900 kyr ago and that the appearance of the Qingyijiang River occurred correspondingly at least before 900 kyr ago on the northern fringe of Mt. huangshan. In view of the almost synchronous age,the establishment of the Qingyijiang River was seemingly a response to the Mid-Pleistocene Revolution when the 100 kyr cycle commenced, and the Kunlun-huanghe movement during the early- middle Pleistocene transition. In addition, the establishment of the Qingyijiang River possibly reflected the birth of the modem Yangtze River to some degree. Therefore the timing of the formation of the Yangtze River is restricted to no later than 900 kyr ago based on the appearance of the Qingyijiang River .

Control policies such as "odd-and-even license plate rule" were implemented by the Chinese government to restrict traffic and suspend factory production in Beijing and neighboring cities during the Asia-Pacific Economic Cooperation summit. We use ozone monitoring instrument(OMI), mobile differential optical absorption spectroscopy(DOAS), and multi-axis differential optical absorption spectroscopy(MAX-DOAS) to measure the variation of the spatial and temporal patterns of NO2 column densities from October 24, 2014 to November 22, 2014. It is found that the NO2 column densities during the episode of control policies are significantly lower than those during other periods, and the emission flux of NO2 calculated by mobile DOAS is also lower than the results from other periods. Some daily low NO2 column densities occur with the northwest wind direction. We then compare the relationship between OMI and mobile DOAS NO2 column density observations, and the results of mobile DOAS are approximately 2.7 times larger than the OMI values. The largest discrepancy occurs in the northern part of Beijing city. In other parts, the two instruments have a better correlation coefficient(R2) of 0.61. The low NO2 column densities that occur during the episode of control policies are affected by the control policies as well as meteorological conditions.

为了解未来气候和土地利用变化综合作用下白鹤(Leucogeranus leucogeranus)越冬适宜生境的分布格局变化特征,基于72个白鹤分布位点和10个环境变量构建白鹤越冬分布与环境因子的关系,识别其潜在适宜生境分布,预测未来气候及土地利用变化情景下白鹤潜在适宜生境分布的时空变异和发展趋势.结果表明:(1)距水源距离、海拔、最干季降水量、坡度、最冷季平均温度以及距城镇距离是影响白鹤越冬分布的主导环境因子.(2)当前(2020)气候及土地利用情景下,白鹤高适生区面积为1.26×10^(4) km^(2),主要分布于江西鄱阳湖、湖南洞庭湖、湖北龙感湖、安徽升金湖、江苏盐城、山东黄河三角洲等气候温和湿润、地势平缓且人为干扰强度相对低的低海拔湿地.(3)SSP126(低排放)、SSP245(中排放)和SSP585(高排放)情景下,白鹤适生区面积均大幅度缩减,未来(2050-2090)平均面积的缩减比例依次为28.69%、34.02%和43.22%.(4)未来气候及土地利用变化情景下,白鹤适宜生境表现为大幅度收缩和小幅度扩张.收缩区域主要集中于长江中下游湿地,扩张区域则分布于莱州湾、渤海湾和辽东湾地区.(5)气候和土地利用共同导致了白鹤适宜生境面积的缩减.气候特别是最干季平均温度的升高,是导致白鹤分布质心向东北高纬度地区迁移的主要因素.总体而言,气候和土地利用变化将对白鹤分布产生负面影响,导致其越冬适宜生境的收缩和破碎化,加剧其灭绝风险,应采取措施加强白鹤种群及其生境的保护和管理.

自言自语,指自己对自己说话。它是人类一种普遍的心理、生理和语言现象。自言自语作为一种人内传播,能帮助言说主体调节情绪,从而达到某种程度的放松与自我满足、自我反省,有着积极的作用。自言自语在一定的条件下能够从人内传播向人际传播转化,其转化条件包括场合、目的与他人接话。传递言外之意和保持主动地位是说给你听这类作为语用修辞策略的自言自语的两个基本的语用修辞功能,在此基础上,可以派生出许多具体的语用修辞功能。

本文报道了皖南叶附生苔4科10属17种,较前记录增加了3科7属15种;11种为安徽省新记录,其中粗柱疣鳞苔(新拟名)(Cololejeunea ornata Ev.)为中国新记录;原为热带太平洋岛屿分布的狭瓣细鳞苔(Lejeuneaborneensis Horik.)首次在大陆上被发现.皖南叶附生苔种类丰富,仅次于福建武夷山而在华东地区居第二位.尖叶薄鳞苔(Leptolejeuneaelliptica)、尖舌扁萼苔(Radula acuminata)、棉毛疣鳞苔(Cololejeunea floccosa)和狭叶残叶苔(Leptocolea oblonga)是组成本地区叶附生苔群落的常见种.对附主植物的研究表明叶附生苔对附主的选择并不严格,光滑无毛,质地较厚的叶面似更适合叶附生苔的生长.
