Introduction Short bowel syndrome(SBS)is a disorder characterized by malabsorption due to the absence or resection of a long small intestine tract,with an incidence of 2 per million of *** adults,SBS is defined as less than 200 cm without colon and less than 50 cm with residual colon in continuity[1].The causes of SBS in adult patients are different,but the most frequent one(33.3%of the cases)is the need for surgery in patients with Crohn’s disease(CD)[2].

Reperfusion of myocardial tissue is the main goal of primary percutaneous coronary intervention(PPCI) with stent implantation in the treatment of acute ST-segment elevation myocardial infarction(STEMI). Although PPCI has contributed to a dramatic reduction in cardiovascular mortality over three decades, normal myocardial perfusion is not restored in approximately one-third of these patients. Several mechanisms may contribute to myocardial reperfusion failure, in particular distal embolization of the thrombus and plaque fragments. In fact, this is a possible complication during PPCI, resulting in microvascular obstruction and no-reflow phenomenon. The presence of a visible thrombus at the time of PPCI in patients with STEMI is associated with poor procedural and clinical outcomes. Aspiration thrombectomy during PPCI has been proposed to prevent embolization in order to improve these outcomes. In fact, the most recent guidelines suggest the routine use of manual aspiration thrombectomy during PPCI(class Ⅱa) to reduce the risk of distal embolization. Even though numerous international studies have been reported, there are conflicting results on the clinical impact of aspiration thrombectomy during PPCI. In particular, data on long-term clinical outcomes are still inconsistent. In this review, we have carefully analyzed literature data on thrombectomy during PPCI, taking into account the most recent studies and meta-analyses.

汽车行驶稳定动力学优化控制,旨在通过确定汽车行驶状态下纵向车速、横摆角速度、质心侧偏角等重要的状态变量,提前预知汽车未来时刻的可能的行驶状态,并将其输送到汽车底盘主动控制系统,实现动力学优化控制,提高汽车的主动安全性,减少道路交通事故。寻找一种低成本、高精度且能够实时获得车辆重要状态参数的方法,是汽车稳定行驶动力学优化控制的关键技术之一。利用Matlab/Simulink仿真工具,分别建立了汽车动力学仿真模型和车辆行驶状态Kalman滤波估计仿真模型,可以同时实现对车辆行驶状态的仿真和对车辆行驶过程中横摆角速度、侧向加速度和质心侧偏角的估计,并且模型具有可扩展性。最后进行了实车场地试验,完成了阶跃曲线、双移线等操作,通过模型仿真、试验数据和状态估计结果的比较得出,三者一致性较好,同时验证了车辆动力学仿真模型和状态估计算法仿真模型的有效性和通用性。

AIM To investigate by immunostaining glucose transporter expression in human colorectal mucosa in controls and patients with inflammatory bowel disease(IBD). METHODS Colorectal samples were obtained from patients undergoing lower endoscopic colonoscopy or rectosigmoidoscopy. Patients diagnosed with ulcerativecolitis(n = 18) or Crohn's disease(n = 10) and scheduled for diagnostic colonoscopy were enrolled. Patients who underwent colonoscopy for prevention screening of colorectal cancer or were followed-up after polypectomy or had a history of lower gastrointestinal symptoms were designated as the control group(CTRL, n = 16). Inflammatory status of the mucosa at the sampling site was evaluated histologically and/or endoscopically. A total of 147 biopsies of colorectal mucosa were collected and processed for immunohistochemistry analysis. The expression of GLUT2, SGLT1, and GLUT5 glucose transporters was investigated using immunoperoxidase labeling. To compare immunoreactivity of GLUT5 and LYVE-1, which is a marker for lymphatic vessel endothelium, doublelabeled confocal microscopy was used. RESULTS Immunohistochemical analysis revealed that GLUT2, SGLT1, and GLUT5 were expressed only in short epithelial portions of the large intestinal mucosa. No important differences were observed in glucose transporter expression between the samples obtained from the different portions of the colorectal tract and between the different patient groups. Unexpectedly, GLUT5 expression was also identified in vessels, mainly concentrated in specific areas where the vessels were clustered. Immunostaining with LYVE-1 and GLUT5 antibodies revealed that GLUT5-immunoreactive(-IR) clusters of vessels were concentrated in areas internal to those that were LYVE-1 positive. GLUT5 and LYVE-1 did not appear to be colocalized but rather showed a close topographical relationship on the endothelium. Based on their LYVE-1 expression, GLUT5-IR vessels were identified as lymphatic. Both inflamed and nonin

减少二氧化碳排放,放特别是减少汽油发动机的二氧化碳排放是目前正在急剧上升的一项要求。从能源的生命周期考虑,能源载体即化石燃料是产生二氧化碳排放问题的根本原因。采用从可再生能源中提炼出的合成燃料(eFuel),可使汽油发动机接近或达到二氧化碳排放的碳中和要求,因此配置eFuel的成分和性质至关重要,因为它将影响汽油发动机的工作过程和效率。eFuel的成分变化会显著影响汽油发动机的喷射、混合气形成、燃烧,以及后氧化和排气后处理等过程,因此,*** AG和FKFS合作开展了一系列相关研究,将不同的eFuel在单缸发动机试验台和喷雾试验台上进行了测试,并将其结果用于标定三维流体的仿真模型。同时,对eFuel的组成、混合气形成及燃烧特性进行深入分析,旨在提高汽油发动机效率,同时改善碳排放效果。除了进行单缸发动机测试外,还对汽油发动机配置进行虚拟优化,即通过替代燃料与发动机优化的相结合来提升汽油发动机的效率。
