Leptospirosis has historically been a severe public health concern across multiple Chinese provinces. Despite an overall decline in incidence recent years, the disease continues to exhibit fluctuations and occasionally triggers localized outbreaks. This study aimed characterize demographic spatiotemporal patterns of leptospirosis Anhui Province - significant epidemic region from 2004 2023, investigate potential climatic environmental risk factors, identify critical targets for prevention...
Patients undergoing general anesthesia frequently encounter difficulties when the conventional nasogastric tube (NGT) is placed, resulting in low success rates. This study investigates a novel, free-hand, and blind technique aimed at enhancing first-attempt rate without need for any medium. One hundred thirty-two eligible patients were randomly allocated to either experimental group or control group. In group, patients' heads turned 45-90° right while supine position, NGT was inserted...
摘要: 漠河盆地位于蒙古‒鄂霍茨克缝合带(MOSB)东段南缘,是研究蒙古‒鄂霍茨克洋东段演化的绝佳窗口.本文对漠河盆地东缘出露的绣峰组砂岩进行详细的岩相学、U-Pb锆石定年和主微量元素地球化学分析,综合前人研究成果,限定了蒙古‒鄂霍茨克洋乃至中亚造山带东段演化历史.结果表明,绣峰组砂岩碎屑物磨圆度较低、分选差,表现出近源剥蚀的特点;U-Pb锆石定年共获得217个谐和年龄,可划分为3个年龄组,其峰值均与盆地南缘额尔古纳地块的岩浆事件相吻合,其中最年轻的碎屑锆石206Pb/238U年龄加权平均值为158±2 Ma(N=5);样品相对富集大离子亲石元素(LILEs)和轻稀土元素(LREEs),亏损高场强元素(HFSEs)和重稀土元素(HREEs),具有明显的Eu负异常.样品源岩为上地壳长英质岩石,形成于大陆岛弧的构造环境,源区可能为漠河盆地南侧的大陆岛弧、额尔古纳地块以及盆地的古老基底.综上所述,绣峰组的最大沉积年龄为晚侏罗世,物源区构造背景为活动大陆边缘的大陆岛弧环境,形成于晚侏罗世蒙古‒鄂霍茨克洋向南俯冲、闭合造山的构造背景下,指示在绣峰组沉积时期(约158...
This article presents new zircon U–Pb ages, data on whole‐rock major and trace elements for the Early Ordovician to Cretaceous granitic rocks exposed in Mohe Basin of North‐east China, reveals tectonic evolution history area during this period. The dating results indicate that magmatic activities from can be divided into six stages, which are ~473, ~281, ~247, ~215, ~130, ~124 Ma, respectively. mainly originated by partial melting a depleted heterogeneous lower crust, except quartz diorites...
摘要: 辽北清原地区位于华北板块北缘东段,是研究古太平洋构造域的典型地区之一.研究区中生代岩浆岩的成因及构造背景对认识古太平洋构造域的演化具有重要意义.本次研究对清原夏家堡地区辉长苏长岩、石英闪长岩和花岗闪长岩进行了锆石U-Pb年代学和岩石地球化学分析.锆石U-Pb测年结果表明,辉长苏长岩形成于中侏罗世晚期((163.8±2.4)Ma),石英闪长岩形成于中侏罗世中期((169.9±2.2)Ma),花岗闪长岩形成于中侏罗世中期(169.9~167.3...
This study investigates the influence of CYP3A4 gene polymorphisms on postoperative pain sensitivity and analgesic response in lung cancer patients undergoing intercostal nerve block with local anesthetics. Sixty (ages 31-74) thoracoscopic surgery were enrolled divided into two groups based expression level: Group I (high CYP3A4) II (low CYP3A4). Postoperative was assessed using Visual Analogue Scale (VAS), patient-controlled intravenous analgesia (PCIA) pump usage, ECG ST-T segment changes,...
The tectonic evolutionary history between the Xing'an Block (XB) and Songnen (SB) in eastern Central Asia Orogenic Belt (CAOB) has been hotly debated. In this study, we present a series of new data to provide better constraint on magmatic process during plate subduction its implications for regional evolution XB SB, even CAOB. whole-rock geochemistry zircon U-Pb chronology syenogranite Chaihe area Great Range have carried out. dating results show that was formed Late Carboniferous...
摘要: 大兴安岭扎兰屯南部位于中亚造山带东段，兴安地块（XB）与松嫩地块（SB）之间，是探究兴安地块与松嫩地块构造演化过程，乃至中亚造山带东段微地块聚合过程的关键地区. 对该地区出露的花岗质糜棱岩进行地质学、地球化学、锆石U-Pb测年分析，以期查明板块俯冲过程中的岩浆作用特征，并尝试限定兴安地块与松嫩地块碰撞拼合时间.LA-ICP-MS锆石U-Pb测年结果表明，花岗质糜棱岩分为两期：Ⅰ期为早泥盆世（~398.8 Ma），Ⅱ期为晚泥盆世末‒早石炭世（351.6~365.7 Ma）. 两期岩石均具有高SiO2（68.20%~77.90%），富碱（K2O+Na2O=6.32%~9.67%），贫镁（MgO=0.22%~0.97%），偏铝质，高钾钙碱性系列的特征. 稀土元素分布模式均为右倾[（La/Yb）N=4.33~10.77]，Eu负异常（δEu=0.03~0.13），富集LILE，亏损HFSE，具有Ⅰ型花岗岩的特征. 两期花岗质糜棱岩可能为俯冲背景下岛弧岩浆活动形成的Ⅰ型‒分异Ⅰ型花岗岩....
