吉林省38所医院护理工作抽查情况分析

吉林省第一周期的医院评审工作基本结束,为了巩固成果,防止滑坡,吉林省医院评审委员会多次组织专家对38所二三级甲乙等医院护理工作进行现场抽查。对吉林省护理工作的概况及抽查中发现的共性问题进行了分析。同时建议:加强护理人员的职业道德教育;解决护理人员编制不足问题;提高护理人员技术劳务价值;运用激励手段提高护理工作质量。     

急性脑出血患者血清白介素-6和转化生长因子-β1含量的变化及其临床意义

目的探讨急性脑出血患者血清白介素-6(IL-6)和转化生长因子β1(TGF-β1)水平在发病过程中的动态变化及其临床意义.方法采用双抗体夹心法检测30名正常人(对照组)和30例急性脑出血患者病后第1、3、7、14 d的血清IL-6和TGF-β1浓度.结果脑出血组在病程第1、3、7 d血清IL-6水平均比对照组明显增高(均P<0.05),TGF-β1水平均明显减低(均P<0.05),至第14 d血清IL-6、TGF-β1水平均接近正常水平.血清IL-6水平在病程第1 d达到峰值(P<0.05),TGF-β1在病程第3 d为低谷值(P<0.05).大量脑出血患者血清IL-6水平均明显高于中、小量出血患者(均P<0.05).不同出血量患者之间TGF-β1水平的差异无显著性(P>0.05).神经功能缺损程度与血清IL-6水平呈正相关(r＝0.625,P<0.05),与TGF-β1水平无关(r＝0.001,P>0.05).IL-6水平与TGF-β1水平无明显相关性.结论 IL-6、TGF-β1与脑出血的病理过程有密切关系.血清IL-6浓度测定对判断脑出血的病情严重程度有一定意义.     

Small bowel rupture after blunt trauma: Computed tomographic signs and their sensitivity

The purpose of this study is to describe the characteristic computed tomographic (CT) signs of small bowel perforation after blunt abdominal trauma and to evaluate their sensitivity. Nineteen preoperative CT scans were obtained from 16 patients with surgically proven small bowel rupture secondary to blunt abdominal trauma. Only the CT findings described in the original CT reports were used. Eleven of 19 CT scans (58 %) had findings that were unequivocal for bowel rupture (i.e., extraluminal air and/or extravasation of oral contrast medium). Seven CT scans (37 %) had findings that were suggestive of severe small bowel injury (i.e., focal small bowel wall thickening and/or free peritoneal fluid without other accompanying organ injuries). In all, 95 % of cases of small bowel rupture had either pathognomonic or suggestive CT findings. One CT scan did not demonstrate small bowel wall thickening, although a hemoperitoneum was present. CT is a sensitive method for suggesting severe small bowel injury and rupture secondary to blunt abdominal trauma.     

2010—2021年国内外老年多重慢病研究热点分析

背景 随着人口老龄化进程的加快,同时患有多种慢病已成为老年人的常态,老年多重慢病相关研究也不断丰富,但鲜有对其研究进展及热点进行分析。目的 分析国内外老年多重慢病的研究热点,揭示近十年来（2010—2021年）老年多重慢病领域研究前沿的热点主题,为相关研究者追踪前沿信息提供参考。方法 基于文本挖掘技术和文献计量学等方法,检索Web of Science核心合集、Scopus、中国知网、万方数据知识服务平台、维普网、PubMed、中华医学会期刊全文数据库、APA-PsycINFO美国心理学会数据库中老年多重慢病领域的相关文献,检索时间为2010—2021年。使用CiteSpace 6.1.3、PASW 18、BICOMB 2.04等软件对文献的发文量趋势、来源、作者、机构、关键词等方面进行分析及可视化,并绘制战略坐标图对领域研究热点进行分析。结果 最终纳入老年多重慢病相关文献9 392篇,其中外文文献5 776篇,中文文献3 616篇。2010—2021年老年多重慢病领域中外文献发文量均呈指数型增长,中文文献年增长率为13.27%,外文文献年增长率为15.84%,该领域正处于发展阶段。中...     

基于太赫兹时域光谱技术的名贵动物药材龟甲的真伪品鉴别

目的： 建立一种利用太赫兹时域光谱和多种化学计量学方法鉴别龟甲真伪的新方法。方法： 选用正品乌龟和伪品红耳彩龟的腹甲进行实验,先用经典的性状鉴别、显微鉴别方法比较两种样品的典型性状特征,后利用太赫兹时域光谱仪测得样品的光谱信息,对样品谱图进行平滑处理和基线校准,并运用化学计量方法进行数据分析以区分正品和伪品龟甲。结果： 性状鉴别结果显示完整正、伪品龟甲样品仅有细微差异,且其碎片或粉末基本无差异;显微鉴别未在两种样品中发现明显的特征差异性结构;两种样品的太赫兹时域光谱曲线图经快速傅里叶变换滤波器平滑滤波处理、正交偏最小二乘法判别分析处理后呈现显著差异。结论： 利用太赫兹时域光谱技术结合正交偏最小二乘法判别分析可以实现龟甲真伪品的精准鉴别。     

Renal and hormonal effects of alpha1-adrenoceptor blockade by bunazosin in essential hypertension

Summary The renal and hormonal effects of the ₁-adrenoceptor blocker bunazosin were examined in 6 patients with essential hypertension. Oral bunazosin for 4 to 12 weeks significantly decreased mean blood pressure by 10%, increased effective renal blood flow and creatinine clearance by 34% and 37%, respectively, the plasma norepinephrine concentration was elevated by 60%, and the plasma atrial natriuretic peptide level was lowered by 22%. The plasma renin activity and aldosterone concentration were unchanged. Thus, a moderate reduction in blood pressure was produced by bunazosin treatment while maintaining renal perfusion.
