背景:与传统的缝合方式相比,采用补片修复腹壁缺陷的无张力疝修补手术能有效减少术后疼痛和疝气复发率,已经成为近年来治疗腹疝的首选方法。目的:归纳总结不同疝修复补片在应用过程中的优缺点。方法:以“腹壁缺损,疝气补片,疝气治疗”为中文检索词,以“abdominal wall defect,hernia patches,hernia treatment”为英文检索词,分别检索中国知网、谷歌学术和PubMed数据库,检索时限主要为2018年1月至2024年2月,同时采用少数经典的早期文献以概述疝修复补片的发展历程,通过阅读题目和摘要进行初步筛选,排除与疝修复材料相关性较低的文献,最终纳入90篇文献进行归纳总结。结果与结论:根据制备材料的不同可以将疝修复补片分为不可吸收人工合成补片、可吸收人工合成补片、天然高分子补片和复合补片。不可吸收补片具有较高的机械强度,有益于疝气区域的组织愈合,但体内长期存在的补片可能会引发身体的免疫反应,导致炎症和疼痛。可吸收人工合成补片与天然高分子补片具有良好的组织相容性、降解性,但机械强度不稳定。复合材料补片继承了传统不可吸收补片优良的机械性能,同时通过可吸收部分的设计降低了一些并发症发生的风险。在疝修复补片的后续研究中,科研人员应重点关注如何将新技术与复合补片结合起来,形成多功能的疝修复补片。

Adaptive output regulation of uncertain nonlinear systems with unknown control directions

作者： jingyu chen Zhenhong LI Zhengtao DING School of Electrical and Electronic Engineering University of Manchester

Dear editor,The output regulation problem for nonlinear systems with unknown exosystems has been an important research topic over the last few decades [1].The early results commonly assume that the sign of the high-frequency gain is known. It is shown [2]that a nonlinear system can be transformed into a special observer form under geometric coordinate-

Mono-functionalized pillar[n]arenes: Syntheses, host–guest properties and applications

引用

Chinese Chemical Letters 2024年第1期35卷 16-30页

作者： Wenzhi Yang Wenjie Zhang jingyu chen Jiong Zhou Department of Chemistry College of SciencesNortheastern UniversityShenyang 110819China

Pillar[n]arenes are a novel class of macrocyclic hosts reported by Ogoshi and co-workers in 2008. Because of their rigid pillar structures, interesting host-guest properties and ease of modifications, pillar[n]arenes have been developed rapidly in the field of functional materials and biomedicine. The modifications of pillar[n]arenes at different positions can give them varied characteristics. Functional groups can be introduced into one position of pillar[n]arenes without changing host-guest properties of pillar[n]arenes. A series of pillar[n]arene dimers, trimers, tetramers and metallacycles can be constructed by mono-functionalized pillar[n]arenes. In this review, two synthetic methods of mono-functionalized pillar[n]arenes are summarized and structures containing mono-functionalized pillar[n]arenes are described. Furthermore, the applications of mono-functionalized pillar[n]arenes in different fields (e.g., supramolecular polymers, sensors, molecular machines, catalysis, biological applications and light-harvesting systems) are also introduced. Hopefully, this article will be useful for researchers studying pillar[n]arenes, especially the mono-functionalized pillar[n]arenes.

Reasoning about knowledge, belief and certainty in hierarchical multi-agent systems

Multi-agent systems （MAS） have received exten- sive studies in the last decade. However, little attention is paid to investigation on reasoning about logics in MAS with hier- archical structures. This paper proposes a complete quantified temporal KBC （knowledge, belief and certainty） logic and corresponding reasoning in hierarchical multi-agent systems （HMAS）. The key point is that internal beliefs and certainty, and external belief and certainty are considered in our logic. The internal beliefs and certainty show every agent is au- tonomous, while the external belief and certainty indicate the mutual influence of mental attitudes between two different agents on different layers in HMAS. To interpret this logic, we propose four classes of corresponding quantified interpreted systems, and define first-order KBC axiomatisations over HMAS, which are sound and complete with respect to the corresponding semantical classes. Finally, we give a case study to show the advantages in terms of expressiveness of our logic.

Lung transplantation for bronchiolitis obliterans syndrome after allogenic hematopoietic stem cell transplantation

Frontiers of Medicine 2018年第2期12卷 224-228页

Bronchiolitis obliterans syndrome （BOS） after hematopoietic stem cell transplantation （HSCT） is a major cause of morbidity and mortality with limited treatment options. Lung transplantation （LTX） has been rarely reported as a treatment option for selected HSCT recipients with this problem. In the present study, we reported six patients who underwent LTX due to BOS after HSCT （two females, four males） from January 2012 to December 2014 in our center. The median time from HSCT to diagnosis of BOS was 2.5 years （ranging from 1 to 5 years）. At a median time of 4 years （ranging from 2 to 5 years） after diagnosis of BOS, four patients received bilateral sequential LTX, and two patients received single LTX. One of the recipients suffered from mild acute rejection after LTX, another suffered from primary lung graft dysfunction on post-operation day 2, and three experienced fungal infections. The median time for follow-up after LTX was 19.5 months （ranging from 12 to 39 months）. At present, all patients are alive with good functional capacity and no relapse of BOS and hematologic malignancy conditions. Patients who received bilateral LTX have better pulmonary functions than patients who received single LTX.

Electrospinning and calcination technique have been combined to fabricate N-doped carbon nanofibers(N-CNFs)by introducing amino grafted few-layered hexagonal boron nitride(amino@BN)into polyacrylonitrile(PAN)matrix as filler followed by *** the high N-doping level(10.7%,atomic fraction)with the final product,the as-prepared N-CNFs exhibit interesting surface wettability(superamphiphilicity in air and underwater oleophilicity).Moreover,compared with pristine PAN derived carbon nanofibers(marked as CNFs),N-CNFs exhibit higher graphic structure under fixed carbonizing temperature as *** these advantages aforementioned,the as-prepared N-CNFs exhibit good specific capacitance(ca.200.1 F/g)without activation treatment at the current density of 0.5 A/g in three-electrode configuration,which is about 149%that of CNFs(ca.134 F/g).What’s more,our N-CNFs also display the unexpected capacity to demulsify diverse surfactant free oil-in-water emulsions by simple filtration in large scale with the high water flux ca.(23578±150)L·m^(−2)·h^(−1).
