背景小儿消化不良(即小儿功能性消化不良)是儿科临床常见病症,复发率较高,严重的小儿消化不良会影响儿童营养摄入,进而影响儿童身体生长发育乃至心理健康。目的对肠炎宁颗粒治疗小儿消化不良的有效性和安全性进行系统评价。方法计算机检索中文数据库:中国知网、万方数据知识服务平台、维普网、中国生物医学数据库,外文数据库:PubMed,The Cochrane Libarary,EMBase,Web of Science;检索时间从建库起至2021年5月,筛选出肠炎宁颗粒治疗小儿消化不良的随机对照试验(RCT),试验组使用肠炎宁颗粒或肠炎宁颗粒联合西医常规治疗(金双歧或吗丁啉);对照组为中成药常规治疗(小儿喜食片)或西医常规治疗(金双歧或吗丁啉),且不含肠炎宁颗粒,用药剂量、给药方式和疗程不限;主要结局指标为显效率,次要结局指标为不良反应发生率、临床症状消失时间。应用Cochrane Handbook 5.1评价标准和RevMan 5.3评价软件对最终纳入的研究进行Meta分析。结果共纳入6项研究进行Meta分析,包含1150例患儿,试验组575例,对照组575例。Meta分析结果显示:肠炎宁颗粒治疗小儿消化不良的显效率高于中成药常规治疗〔RR=1.57,95%CI(1.27,1.94),P0.05);肠炎宁颗粒联合西医常规治疗小儿消化不良临床症状消失时间短于单用西医常规治疗(P<0.05)。结论基于现有数据和方法,肠炎宁颗粒单用或联合西医常规治疗可提高显效率、缩短临床症状消失时间,且不良反应发生率相对较低。但由于纳入研究质量不高,欲得到更有力的证据,还需采用大样本、设计严谨、符合国际规范的临床试验方案提高证据质量级别。

目的分析单张纸胶印的递纸机构,寻求当最高印刷速度提高时需要改进的设计环节。方法采用实验模态法对单张纸胶印机的递纸机构进行分析,将实验模态分析技术引入递纸机构动态响应的求解过程,并通过求解结果指导并改进设计。结果在有样机可提供测试的情况下,用试验模态分析方法建模的精度会高于常用的单自由度集中质量法,对系统进行测试分析能够达到更准确的结果。运用该方法将一款单张纸胶印机的最高速度由13 000张/h提高到了16 500张/h。结论试验模态方法能为胶印机的改进设计提供依据,既是结构设计和动力学设计的有效补充,也是校核的工具。其他关键机构如输纸头、前规和咬牙开闭机构等凸轮连杆机构也可以使用此方法进行分析研究。

身体政治是身体美学研究的一个重要范畴,它将身体从生物学层面中抽离出来,在政治和社会层面加以审视,从而摆脱以往的固有阈限,得出更为综合的结论。笔者运用权力话语、德勒兹生成理论,全面考察巴勒斯围绕身体所构建的独特的文学世界。具体而言,巴勒斯通过肉体“辖制”与欲望“生成”两种维度,对身体政治加以展现,一方面深刻揭示出隐性资本权力与技术主义对身体的强烈控制;同时也展现出对“赤裸生命”的本能追求。

In this paper, we study the consensus problem for multi-agent systems under a directed graph. First, the velocity-free consensus algorithm for double-integrator dynamics is proposed, in which the graph theory and Lyapunov stability theory are *** proposed consensus algorithm guarantees that the states of all agents can reach consensus asymptotically. Then, the obtained results and techniques are extended to the attitude consensus for multiple rigid bodies. Numerical simulations are given to validate the effectiveness of the proposed method.
