地佐辛超前镇痛对隐匿性阴茎矫治术患儿苏醒期谵妄的临床观察
目的观察地佐辛超前镇痛对隐匿性阴茎矫治术患儿苏醒期谵妄(ED)的影响。方法筛选2020年7月至2020年10月62例6~10岁拟行隐匿性阴茎矫治术的男孩,按随机数字表法分为生理盐水对照组(C组,n=32例)和地佐辛组(D组,n=30例),所有患者均采用静吸复合全麻(喉罩)。2组分别在麻醉诱导前5 min给予等容量的0.9%生理盐水10 mL或地佐辛0.1 mg/kg (0.9%生理盐水稀释至10 mL)。比较2组入PACU即刻(T1)、10 min(T2)、出PACU即刻(T3)、术后1 h(T4)、术后6 h(T5)PAED评分及FLACC疼痛评分;比较2组术后ED、导尿管相关膀胱不适(CRBD)发生率。问卷患儿父母术后48 h内新发适应不良行为发生情况并比较;比较2组麻醉诱导前30 min(T0)、T1、T4、T5外周静脉血皮质醇(Cor)、肾上腺素(E)、血糖(Glu)水平。结果D组在T2 ~ T5点 PAED评分明显低于C组(P<0.001);FLACC评分低于C组(P<0.001);D组ED的发生率明显低于C组(16.67% vs. 40.63%,P=0.039),术后48 h内新发适应不良行为的总发生率低于C组(13.33% vs. 37.50%, P=0.042);CRBD发生率低于C组(6.67% vs. 28.13%,P=0.044)。D组在T1、T4、T5点E、Cor、Glu水平明显低于C组(组间P值分别为P<0.001,P=0.009,P=0.012)。结论地佐辛超前镇痛可明显降低小儿隐匿性阴茎术后ED的发生率;降低术后新发适应不良行为的发生率,可能与地佐辛降低术后疼痛应激及CRBD的发生率有关

THE MAMMALIAN FOSSILS FROM WESTERN TAIWAN STRAIT
本文简要记述了出自台湾海峡西部海域的170件哺乳动物化石,其中的102件分属于urSuSSP,ElEPHASMAXIMuS,dICErOrHInuSSP,CErVuSunICOlOr,CErVuSnIPPOn,SuSSP,和bubAluSbubAluS,时代为更新世晚期;67件属全新世早期,包括CETACEAgEn.ETSP.IdET,ElEPHASSP,SuSSCrOfACErVuSunICOlOr和CErVuSnIPPOn等;属于第三纪晚期的仅有1件鹿超科角化石。台湾海峡西部海域更新世晚期和全新世早期的哺乳动物组合不同于已知的我国海域其他地点的哺乳动物组合,也异于福建中、西部山区的哺乳动物组合。Numerous mammalian Fossils From Western Taiwan Strait were brieFly discri-bed here.Concerning the age, besides an antler of Cervidea dated to late Tertiary,other specimens were suggested to be of late Pleistocene, such as Ursus sp., Elcphasmaximus, Dicerorhinus sp., Sus sp., Cervus unicolor, Cervus nippon and Bubalus bu-balus, and early Holocene, incIuding Cetacea gen.et sp.indet., Elephas sp.Susscrofa, Cervus unicolor and Cervus nippon etc.The Late Pleistocene and Early Holocene Faunal assemblages of Western Tai-wan Strait diFFer From contemporary Faunal assemblages either From other sea areain Cbina or localities at middle-western mountain area in Fujian, they probablyrepresent a local branch of Ailuropoda-Stegodon Fauna occured along the Soutbeasterncoast of China.国家自然科学基

Charge state distribution analysis of Al and Pb ions from thelaser ion source at IMP
<span style="color: rgb(51, 51, 51); font-family: arial, helvetica, sans-serif; font-size: 13px; line-height: 22px; background-color: rgb(248, 248, 248);">A prototype laser ion source that could demonstrate the possibility of producing intense pulsed high charge state ion beams has been established with a commercial Nd:YAG laser (E-max=3 J, 1064 nm, 8-10 ns) to produce laser plasma for the research of Laser Ion Source (LIS). At the laser ion source test bench, high purity (99.998%) aluminum and lead targets have been tested for laser plasma experiment. An Electrostatic Ion Analyzer (EIA) and Electron Multiply Tube (EMT) detector were used to analyze the charge state and energy distribution of the ions produced by the laser ion source. The maximum charge states of Al12+ and Pb7+ were achieved. The results will be presented and discussed in this paper.</span
