高精地图的“非视觉”和面向机器特性,使其与传统面向人的时空产品有明显不同,相应的描述地图主、客体及其与产品之间关系的传输模型也面临巨大变革。已有的传输模型重构了上述关系,包括新增用户个性信息及其传输,但也存在信息传递工具仍采用面向人而非机器的地图语言等不足。为此,结合自动驾驶中地图信息的传输特点,构建面向机器认知的高精地图信息传输模型,通过对已有的传输模型进行扩展:GIS语言代替地图语言,将用户个性信息整合到高精地图的用户图层中,将行动指导扩展为行动实践。研究结果表明,构建的全机器认知的高精地图信息传输模型实现了地图信息认知的主体由人到机器的扩展,适应了高精地图在感知、定位、规划、控制等传输过程中全人工智能的特性。所提出的模型一方面有助于准确把握高精地图的本质及内容结构,提升认知效果;另一方面,对驾驶服务具有重要的指导作用,包括内容选取、表达方法、系统功能框架设计等,提高传输效率。

高精地图是自动驾驶的“传感器”,为自动驾驶提供必要的先验数据以及相应的超视距感知、校验定位、动态规划和决策控制。然而,高精地图数据供给与自动驾驶知识需求仍存在鸿沟,包括数据量大导致查询困难、数据关联弱导致语义理解和智能决策困难。知识图谱是将知识以图的结构表达出来,以描述实体及其关系,涉及实体抽取和关系抽取。为此,在高精地图数据基础上,引入知识图谱,提出高精地图知识图谱的构建方法,以架起地图数据供给与驾驶知识需求之间的桥梁,支撑高精地图数据到自动驾驶知识的转化。构建的知识图谱实例,一方面将高精地图海量数据采用图进行了二次表达,建立了类似于索引的结构;另一方面显式表达了面向自动驾驶需求的语义关系。实验结果表明,知识图谱能为高精地图的语义查询、知识推理和局部决策规划提供基础。所提出的方法能实现高精地图先验数据的语义结构化,推进高精地图由数据到信息到知识的跨越,为自动驾驶的落地贡献先验知识。

Portal vein thrombosis is a common complica- tion in cirrhotic patients. When portal vein thrombectomy is not a suitable option, a large collateral vessel can be used for allograft venous inflow reconstruction. We describe an unusu- al case of successful portal revascularization using the right gastroepiploic vein. The patient underwent a cadaveric or- thotropic liver transplantation with end-to-end anastomosis of the portal vein to the right gastroepiploic vein. Six months after liver transplantation the patient is well with good liver function. The use of the right gastroepiploic vein for allograft venous reconstruction is feasible and safe, with a great advan- tage of avoiding the need of venous jump graft.

反刍动物的甲烷排放量占人为排放源的33%。现有研究的重点在于确定影响肠道甲烷(CH)排放的重要因素,例如采食量、日粮组成和消化率等。目前,日粮优化是国内外相关学者提出的有关CH减排策略中最具可行性的方案之一。本研究系统采用文献搜集、信息提取和Meta分析的方法评估了国内外不同日粮系统下肉牛的肠道甲烷排放情况,合计筛选出22篇文章中的62个实验组,分析了三种不同日粮饲草比例下的肠道甲烷排放,三种饲草比例分别为(1)饲草比例>70%(n=31),(2)饲草比例为15-70%(n=18)和(3)饲草比例70%的日粮组,平均CH排放量分别为140.0 g/头/天,171.52 g/头/天和193.40 g/头/天。针对各日粮组所包含的研究结果,其组内异质性都很高(I>95%;P0.05)。

Acute antibody-mediated rejection after intestinal transplantation

World Journal of Transplantation 2016年第4期6卷 719-728页

作者： Guo-Sheng Wu ruy J Cruz Jr Jun-Chao Cai Division of Gastrointestinal Surgery Xijing Hospital of Digestive Diseases the Fourth Military Medical University Thomas E. Starzl Transplantation Institute University of Pittsburgh Medical Center Terasaki Foundation Laboratory

AIM To investigate the incidence, risk factors and clinical outcomes of acute antibody-mediated rejection(ABMR) after intestinal transplantation(ITx).METHODS A retrospective single-center analysis was performed to identify cases of acute ABMR after ITx, based on the presence of donor-specific antibody(DSA), acute tissue damage, C4 d deposition, and allograft *** Acute ABMR was identified in 18(10.3%) out of 175 intestinal allografts with an average occurrence of 10 d(range, 4-162) after ITx. All acute ABMR cases were presensitized to donor human leukocyte antigens class Ⅰand/or Ⅱ antigens with a detectable DSA. A positive cross-match was seen in 14(77.8%) cases and twelve of 18 patients(66.7%) produced newly-formed DSA following ITx. Histological characteristics of acute ABMR include endothelial C4 d deposits, interstitial hemorrhage, and severe congestion with focal fibrin thrombin in the lamina propria capillaries. Multivariate analysis identified a liver-free graft and high level of panel reactive antibodyas a significant independent risk factor. Despite initial improvement after therapy, eleven recipients(61.1%) lost transplant secondary to rejection. Of those, 9(50%) underwent graft removal and 4(22.2%) received second transplantation following acute ABMR. At an average follow-up of 32.3 mo(range, 13.3-76.4), 8(44.4%) recipients *** Our results indicate that acute ABMR is an important cause of intestine graft dysfunction, particularly in a liver-exclusive graft and survivors are at an increased risk of developing refractory acute rejection and chronic rejection. More effective strategies to prevent and manage acute ABMR are needed to improve outcomes.

Comparison of Clonidine and Metoprolol Effectiveness on the Control of Post-Operative Blood Pressure in Otorhinolaryngology-Head and Neck Surgeries: A Clinical Trial

引用

Open Journal of Anesthesiology 2021年第2期11卷 49-58页

作者： Sérgio Menezes Silvio Caldas Neto ruy Lins Filho Jayme Santos Neto Rossana Lins Universidade Federal de Pernambuco Recife Brazil

Objectives: Adequate control of hemodynamic parameters in patients undergoing otolaryngology-head and neck (OLHN) surgeries is one of the objectives of peri-operative anesthesia management. In this context, we seek to evaluate the effectiveness of metoprolol compared to clonidine in the post-operative control of systolic (SBP) and diastolic (DBP) blood pressures, and heart rate (HR), when these medications are used in the immediate pre-operative period. Method: this is a randomized double-blind clinical trial. Patients over 18 years old, according to the American Society of Anesthesiologists Physical Status Classification (ASA) I or II, who would undergo OLHN surgery, presenting with greater than 140 mmHg (SBP) or 90 mmHg (DBP), upon arrival at the surgical ward, were included in the study. 46 patients were randomized into two groups (C or M) who received clonidine (75 or 150 mcg) or metoprolol (5 or 10 mg), respectively. The averages of SBP, DBP and HR were compared between groups upon arrival at the post anesthesia care unit (PACU) and four hours post-surgery. Results: In group C, SBP (127.7 ± 18.8 vs 137.3 ± 14.1 mmHg, p = 0.03) and DBP (73.1 ± 15.46 vs 82.6 ± 7.9 mmHg, p 0.01) were lower, when compared with group M. No difference was observed in HR immediately upon PACU arrival. In addition, for four hours post-surgery, no change was noted in the SBP, DBP or HR. Conclusion: metoprolol was less effective than clonidine in reducing systolic and diastolic blood pressures in the immediate post-operative period of OLHN surgeries.
