目的本研究通过Meta分析对传统缝合修补与补片修补在治疗巨大食管裂孔疝的效果和安全性进行评价。方法检索Pubmed、Embase和Cochrane数据库所有已发表的有关传统缝合修补对比补片修补治疗巨大食管裂孔疝的临床研究。主要评价指标为复发率和并发症。结果 5项临床试验符合标准入选Meta分析,共有465名研究对象纳入分析。合并分析表明,初次食管裂孔疝传统缝合修补组的复发率是补片修补组的2.5~4倍。长期观察（〉6个月）表明,补片修补组复发危险度OR=0.48（95%CI,0.22~1.01,P=0.05）;随访期内没有观察到因补片引起的脏器损伤。结论补片修补治疗巨大食管裂孔疝是安全的,在降低术后复发率方面优于传统缝合修补,但长期效果有待更多高质量的长期随机对照试验来进一步明确。

Strontium speciation transferring in strontium residue and mixing strontium ore are investigated with extracting experiment, X-ray powder diffraction(XRD), X-ray fluorescence spectrometer(XRF) and Atomic Absorption Spectroscopy(AAS). The results show that there are strontium carbonate, strontium sulfate, strontium sulfide, and a little amount of strontium silicate and strontium ferrite in strontium residue. Impurities in strontium residue mainly contain carbonate and oxide of calcium, iron, magnesium and aluminum etc. The amount of strontium sulfide in strontium residue is larger than that in strontium ore. And a little strontium silicate and strontium ferrite are found in strontium ore. It is concluded that acid soluble method is used firstly in the process of producing strontium carbonate from mixing strontium ore. In addition, mechanical smash method and surface active treatment to strontium samples are beneficial to the ratio-leaching increase of strontium. The research achievement helps to save energy and decrease pollutants emission in strontium processing industry.

A glass frit containing Li_(2)O-MgO-ZnO-B_(2)O_(3)-SiO_(2)component was used to explore the low-temperature sintering behaviors and microwave dielectric characteristics of tri-rutile MgTa_(2)O_(6)ceramics in this *** good low-firing effects are presented due to the high matching relevance between Li_(2)O-MgO-ZnO-B_(2)O_(3)-SiO_(2)glass and MgTa_(2)O_(6)*** pure tri-rutile MgTa_(2)O_(6)structure remains unchanged,and high sintering compactness can also be achieved at 1150℃.We found that the Li_(2)O-MgO-ZnO-B_(2)O_(3)-SiO_(2)glass not only greatly improves the low-temperature sintering characteristics of MgTa_(2)O_(6)ceramics but also maintains a high(quality factor(Q)×resonance frequency(f))value while still improving the temperature ***,great microwave dielectric characteristics when added with 2wt%Li_(2)O-MgO-ZnO-B_(2)O_(3)-SiO_(2)glass can be achieved at 1150℃:dielectric constant,ε_(r)=26.1;Q×f=34267 GHz;temperature coefficient of resonance frequency,τ_(f)=-8.7×10^(-6)/℃.

为探究更加高效、环保的三角梅繁殖方法,以樱花三角梅(Bougainvillea peruviana ‘Imperial Delight’)半木质化枝条为试验材料,比较研究生长调节剂NAA预处理对三角梅水培和基质培扦插生根的影响。结果表明:200 mg/L NAA预处理能促进三角梅水培和基质培扦插生根;但在相同NAA浓度下,基质培各组生根率均高于水培组,且生根数及根长情况也优于水培组;根粗细及颜色与扦插方式无关。说明200 mg/L的NAA适合‘樱花’三角梅扦插繁殖;同时,水培扦插方式还需进一步优化。

目的:了解首次参加在线巴林特小组者对在线工作方式的意见和体验,为改善和推广在线巴林特小组工作提供参考。方法:自行设计参加巴林特小组工作前和工作后调查问卷,于小组工作前后分别通过微信平台发给参与者,由其自愿完成线上匿名调查。收集有效问卷101份。结果:本研究纳入在线巴林特小组参与者101名,女性成员88名(87.1%),上海地区81名(80.2%)。参与者均对巴林特小组工作有一定了解。29名参与者进组工作,72名参与者在组外观摩。在对小组工作的5项体验和小组进程8个指标的评价等方面,进组成员与观摩人员间差异皆无统计学意义(p>0.05)。在线小组工作后,参与者最担心的三项分别是参与过程中容易被周围的事物打扰;网络环境不安全,有人录音和录像;情绪和非语言的表达受限。结论:作为传统巴林特小组工作形式的有益补充,疫情期间在线巴林特小组工作可以作为线下面对面小组工作的扩展,得到了参与者的认可,今后也可以成为值得推广的长期工作形式。在线巴林特小组工作中需特别强调保密协议和安全设置。
