AIM: To identify risk factors related to pancreatic fistula in patients undergoing distal pancreatectomy (DP) and to determine the effectiveness of using a stapled and a sutured closed of pancreatic stump. METHODS: Sixty-four patients underwent DP during a 10-year period. Information regarding diagnosis, operative details, and perioperative morbidity or mortality was collected. Eight risk factors were examined. RESULTS: Indications for DP included primary pancreatic disease (n = 38, 59%) and non-pancreatic malignancy (n = 26, 41%). Postoperative mortality and morbidity rates were 1.5% and 37% respectively; one patient died due to sepsis and two patients required a reoperation due to postoperative bleeding. Pancreatic fistula was developed in 14 patients (22%); 4 of fistulas were classified as Grade A, 9 as Grade B and only 1 as Grade C. Incidence of pancreatic fistula rate was significantly associated with four risk factors: pathology, use of prophylactic octreotide therapy, concomitant splenectomy, and texture of pancreatic parenchyma. The role that technique (either stapler or suture) of pancreatic stump closure plays in the development of pancreatic leak remains unclear. CONCLUSION: The pancreatic fistula rate after DP is 22%. This is reduced for patients with non-pancreatic malignancy, fibrotic pancreatic tissue, postoperative prophylactic octreotide therapy and concomitant splenectomy.

目的：旨在评价在开放性网膜疝修补术中，通过采用不同的保留生殖股神经的生殖支、髂腹股沟神经、髂腹下神经的手术方案，是否能有效缓解慢性术后疼痛。背景：近年来，出于对其治疗和法律意义的关注，疝修补术后出现的慢性腹股沟疼痛日益引起人们的兴趣。然而，应采取何种治疗方案以保留3支腹股沟感觉神经仍存在许多争议。方法：一项由11家意大利研究中心参与多中心、前瞻性研究、募集了973例疝修补病例。要求所有手术医生报告是否每一根神经都被识别，并予以保留或分离。本研究的主要终点为评价6个月和1年时中重度慢性疼痛的情况。结果：6个月和1年随访时，分别有9．7％和4．1％的患者出现腹股沟疼痛。在6个月时，7．9％的患者为轻度疼痛，2．1％为中重度疼痛，而在1年时，3．6％的患者为轻度疼痛，0．5％的患者为中重度疼痛。单变量和多变量分析显示，并未发现与慢性疼痛存在显著相关的神经，随着未检测到的神经数量的增加，腹股沟疼痛的发生危险也随之增加。同样的，神经分离与慢性疼痛的发生明显相关。结论：目前的研究结果显示，在开放性腹股沟疝修补术中，分辨并保留神经可减少慢性失能性腹股沟疼痛，并且对于大多数6个月时出现慢性疼痛的患者，只有采取保守或内科治疗方法才能缓解其1年时的疼痛症状。

An optimal design method for two materials based on small amplitude homogenization is presented. The method allows to use quite general objective functions at the price that the two materials should have small contrasts in their relevant physical parameters. The following two applications are shown: Stress constrained compliance minimization and defect location in elastic bodies.

Encapsulation of different guestspecies such as molecules and ions inside carbon nanotubes （CNTs） has been reported in the literatures during the last 15 years and repre sents an exciting development of nanoengineering of novel materials and composites. The reported nanocomposite mate rials show the semiconducting properties with potential applications in nanosensors, nanounits and nanocircuits as well as advanced energy transfer and storage properties, and encompass manufacturing for novel nanowires, nanoelectronic devices with properties designed with optoelectronic, spin tronic and nanomagnetic qualities. This review reports on a wide range of encapsulation references with particular focus on single molecules, atomic chains, metal halides and polymers encapsulated inside CNTs. The encapsulation methods and the chemical and physical qualities of these novel materials are crucial for the future manufacturing of novel innovations in nanotechnology, and represent therefore the current stateof theart of encapsulation methods in advanced manufacturing.

Nanomaterials composed of metals and metal alloys are the most valuable components in emerging micro- and nano-electronic devices and innovations to date. The composition of these nanomaterials, their quantum chemical and physical properties, and their production methods are in critical need of summarization, so that a complete state of the art of the present and future of nanotechnologies can be presented. In this review, we report on the most recent activities and results in the fields of spintronics, nanophotonics, and nanomagnetics, with particular emphasis on metallic nanoparticles in alloys and pure metals, as well as in organic combinations and in relation to carbon-based nanostructures. This review shows that the combinatory synthesis of alloys with rare metals, such as scandium, yttrium, and rare earths imparts valuable qualities to high-magnetic-field compounds, and provides unique properties with emphasis on nanoelectronic and computational components. In this review, we also shed light on the methods of synthesis and the background of spintronic, nanomagnetic, and nanophotonic materials, with applications in optics, diagnostics, nanoelectronics, and computational nanotechnology. The review is important for the industrial development of novel materials, and for summarizing both fabrication and manufacturing methods, as well as principles and functions of metallic nanoparticles.
