1整合HPV状态、侵袭模式,形态学和分子标记的宫颈腺癌分类显示文摘宫颈腺癌(ECA)是一组病因、分子驱动因素及形态不同,对治疗的反应和预后各异的肿瘤。HPV筛查及疫苗时代,适当的分类对患者管理至关重要,国际宫颈腺癌标准和分类(IECC)率先突破基于传统形态学的WHO分类,根据高倍镜下HPV相关形态学存在,即有无易于识别的腔缘顶端'漂浮'核分裂和/或凋亡小体,将ECA分为HPV相关性(HPVA)及非HPV相关性(NHPVA)腺癌。该分类简单、实用、可重复,与免疫组化和原位杂交结果高度一致,具有重要临床意义,为过去50年妇科病理学最重要的进展。Park KJ 方三高(译) 魏建国(校) 2020诊断病理学杂志2020,27,5:26

3肽酰基精氨酸脱亚氨酶4和中性粒细胞胞外诱捕网形成在实验性动脉粥样硬化和动脉损伤中的作用:浅表糜烂的影响显示文摘中性粒细胞可能促进人类动脉粥样硬化的血栓并发症的发生。特别是中性粒细胞胞外诱捕网(neutrophil extracellular traps,NETs)可加剧局部炎症,并放大和加剧动脉内膜损伤和血栓形成。肽酰基精氨酸脱亚氨酶4(peptidyl arginine deiminase 4,PAD4)参与NET的形成,但对该酶在动脉粥样硬化血栓形成中的作用的认识仍然不足。刘青 叶鹏 Franck G Mawson TL Folco EJ Molinaro R Ruvkun V Engelbertsen D Liu X Tesmenitsky Y Shvartz F Sukhova GK Michel JB Nicoletti A Lichtman AH Wagner DD Croce KJ Libby P 2018中华高血压杂志2018,26,5:13
4Treatment of malignant gastric outlet obstruction with endoscopically placed self-expandable metal stents显示文摘Malignant gastroduodenal obstruction can occur in up to 20%of patients with primary pancreatic,gastric or duodenal carcinomas.Presenting symptoms include nausea,vomiting,abdominal distention,pain and decreased oral intake which can lead to dehydration, malnutrition,and poor quality of life.Endoscopic stent placement has become the primary therapeutic modality because it is safe,minimally invasive,and a cost-effective option for palliation.Stents can be successfully deployed in the majority of patients. Stent placement appears to lead to a shorter time to symptomatic improvement,shorter time to resumption of an oral diet,and shorter hospital stays as compared with surgical options.Recurrence of the obstructive symptoms resulting from stent occlusion,due to tumor ingrowth or overgrowth,can be successfully treated with repeat endoscopic stent placement in the majority of the cases.Both endoscopic stenting and surgical bypass are considered palliative treatments and,to date,no improvement in survival with either modality has been demonstrated.A tailored therapeutic approach,taking into consideration patient preferences and involving a multidisciplinary team including the therapeutic endoscopist,surgeon,medical oncologist, radiation therapist,and interventional radiologist, should be considered in all cases.Jill KJ Gaidos Peter V Draganov 2009World Journal of Gastroenterology2009,15,35:12
5Long-term survival following radiofrequency ablation of colorectal liver metastases: A retrospective study显示文摘AIM: To retrospectively evaluate the long-term survivalof patients that received radiofrequency ablation(RFA) therapies of colorectal liver metastases. METHODS: In 2005 to 2008, RFA of 105 colorectal liver metastases(CRLM) were performed on 49 patients in our institution. The liver metastases were evaluated, both before and after ablation therapies, with contrast enhanced computerised tomography and contrast enhanced ultrasonography. Histological evidence of malignant liver metastases was obtained in the few instances where contrast enhanced ultrasonography gave equivocal results. Accesses to the CRLM were guided ultrasonically in all patients. The data obtained from records of these ablations were retrospectively analysed and survival data were compared with existing studies in the literature.RESULTS: 1-, 2-, 3-, 4- and 5-year survival rates, when no stringent selection criteria were applied, were 92%, 65%, 51%, 41% and 29% respectively. To explore the impact of the number and size of CRLM on patients' survival, an exclusion of 13 patients(26.5%) with number of CRLM ≥ 5 and tumour size ≥ 40 mm resulted in 1-, 2-, 3-, 4- and 5-year survival rates improving to 94%, 69%, 53%, 42% and 31% respectively. It is of note that 9 of 49 patients developed extra-hepatic metastases, not visible or seen on pretreatment scans, just after RFA treatment. These patients had poorer survival. The development of extra-hepatic metastases in nearly 20% of the patients included in our study can partly account for modestly lower survival rates as compared with earlier studies in the literature.CONCLUSION: Our study underscores the fact that optimum patients' selection before embarking on RFA treatment is vitally important to achieving a superior outcome.Simeon Niyi Babawale Thomas MandФe Jensen Jens BrФndum FrФkjr 2015World Journal of Gastrointestinal Surgery2015,7,3:11

7Voltage regulation in LV grids by coordinated volt-var control strategies显示文摘The increasing penetration level of photovoltaic(PV)power generation in low voltage(LV)networks results in voltage rise issues,particularly at the end of the feeders.In order to mitigate this problem,several strategies,such as grid reinforcement,transformer tap change,demand-side management,active power curtailment,and reactive power optimization methods,show their contribution to voltage support,yet still limited.This paper proposes a coordinated volt-var control architecture between the LV distribution transformer and solar inverters to optimize the PV power penetration level in a representative LV network in Bornholm Island using a multi-objective genetic algorithm.The approach is to increase the reactive power contribution of the inverters closest to the transformer during overvoltage conditions.Two standard reactive power control concepts,cosu(P)and Q(U),are simulated and compared in terms of network power losses and voltage level along the feeder.As a practical implementation,a reconfigurable hardware is used for developing a testing platform based on real-time measurements to regulate the reactive power level.The proposed testing platform has been developed within PVNET.dk project,which targets to study the approaches for large PV power integration into the network,without the need of reinforcement.Miguel JUAMPEREZ Guangya YANG Søren Bækhøj KJÆR 2014Journal of Modern Power Systems and Clean Energy2014,2,4:10
8Impaired contractility and remodeling of the upper gastrointestinal tract in diabetes mellitus type-1显示文摘AIM: To investigate that both the neuronal function of the contractile system and structural apparatus of the gastrointestinal tract are affected in patients with longstanding diabetes and auto mic neuropathy. METHODS: The evoked esophageal and duodenal contractile activity to standardized bag distension was assessed using a specialized ultrasound-based probe. Twelve type-1 diabetic patients with autonomic neuropathy and severe gastrointestinal symptoms and 12 healthy controls were studied. The geometry and biomechanical parameters (strain, tension/stress, and stiffness) were assessed. RESULTS: The diabetic patients had increased frequency of distension-induced contractions (6.0 ± 0.6 vs 3.3 ± 0.5, P < 0.001). This increased reactivity was correlated with the duration of the disease (P = 0.009). Impaired coordination of the contractile activity in diabetic patients was demonstrated as imbalance between the time required to evoke the first contraction at the distension site and proximal to it (1.5 ± 0.6 vs 0.5 ± 0.1, P = 0.03). The esophageal wall and especially the mucosa-submucosa layer had increased thickness in the patients (P < 0.001), and the longitudinal and radial compressive stretch was less in diabetics (P <0.001). The esophageal and duodenal wall stiffness and circumferential deformation induced by the distensions were not affected in the patients (all P > 0.14). CONCLUSION: The impaired contractile activity with an imbalance in the distension-induced contractions likely reflects neuronal abnormalities due to autonomic neuropathy. However, structural changes and remodeling of the gastrointestinal tract are also evident and may add to the neuronal changes. This may contribute to the pathophysiology of diabetic gut dysfunction and impact on future management of diabetic patients with gastrointestinal symptoms.Jens BrΦndum FrΦkjΦr SΦren Due Andersen Niels EjskjΦr Peter Funch-Jensen AsbjΦrn Mohr Drewes Hans Gregersen 2007World Journal of Gastroenterology2007,13,36:8
9AKT and ERK1/2 signaling in intrahepatic cholangiocarcinoma显示文摘Intrahepatic cholangiocarcinomas (ICC) are neoplasms that originate from cholangiocytes and can occur at any level of the biliary tree. Surgical resection is the current therapy of choice for this highly aggressive cancer. However, the 5-year survival still is poor, with high recurrence rates. Due to the intrahepatic growth a signifi cant proportion of patients present with advanced disease and are not candidates for curative surgery or transplantation. The existing palliative options are of limited benefit and there is a great necessity for novel therapeutic options. In this article we review the role of the phosphoinositide 3-kinase(PI3K)/ AKT and extracellular regulated kinase (ERK) signaling pathways in ICC and present new data on the prognostic value of these protein kinases. Finally, we discuss future upcoming therapeutic options based on targeting these signaling pathways.KJ Schmitz H Lang J Wohlschlaeger GC Sotiropoulos H Reis KW Schmid HA Baba 2007World Journal of Gastroenterology2007,13,48:8
10Morphological and functional evaluation of chronic pancreatitis with magnetic resonance imaging显示文摘Magnetic resonance imaging(MRI)techniques for assessment of morphology and function of the pancreas have been improved dramatically the recent years and MRI is very often used in diagnosing and follow-up of chronic pancreatitis(CP)patients.Standard MRI including fat-suppressed T1-weighted and T2-weighted imaging techniques reveal decreased signal and glandular atrophy of the pancreas in CP.In contrast-enhanced MRI of the pancreas in CP the pancreatic signal is usually reduced and delayed due to decreased perfusion as a result of chronic inflammation and fibrosis.Thus,morphological changes of the ductal system can be assessed by magnetic resonance cholangiopancreatography(MRCP).Furthermore,secretin-stimulated MRCP is a valuable technique to evaluate side branch pathology and the exocrine function of the pancreas and diffusion weighted imaging can be used to quantify both parenchymal fibrotic changes and the exocrine function of the pancreas.These standard and advanced MRI techniques are supplementary techniques to reveal morphological and functional changes of the pancreas in CP.Recently,spectroscopy has been used for assessment of metabolite concentrations in-vivo in different tissues and may have the potential to offer better tissue characterization of the pancreas.Hence,the purpose of the present review is to provide an update on standard and advanced MRI techniques of the pancreas in CP.Tine Maria Hansen Matias Nilsson Mikkel Gram Jens Brφndum Frφkjr 2013World Journal of Gastroenterology2013,19,42:7

13糖尿病性上消化道感觉和运动功能异常显示文摘糖尿病患者胃肠感觉运动功能异常非常常见,其可涉及胃肠道各个部位。糖尿病性胃肠异常经常是亚临床的,庆幸的是罕有严重和危及生命的问题发生。人们尚未完全了解糖尿病性上消化道感觉运动功能异常的发病机制,但是其机制似乎是多源性的。研究表明,糖尿病性自主神经病变和急性血糖异常可损伤感觉运动功能。糖尿病发展过程中胃肠道结构和生物力学特性的重构也可能与感觉运动功能异常有关。本综述只讨论糖尿病性上消化道感觉运动功能异常,同时结合讨论胃肠道结构和生物力学特性的重构在糖尿病性上消化道感觉运动功能异常发展中的作用。赵静波 Jens Brφndum Frφkjr Asbjφrn Mohr Drewes Niels Ejskjaer 2008医学综述2008,14,23:6
14TKA术后慢性假体周围感染治疗策略的思考——应用决策分析法在一期和二期全膝翻修术中寻找最佳策略显示文摘随着全膝关节置换术(total knee arthroplasty,TKA)手术量的逐年增加,术后假体周围感染(periprosthetic joint infection,PJI)受到越来越多的关注。尽管二期翻修手术被认为是治疗PJI 的金标准,但术后仍有很高的再发率和死亡率。与之相比,一期翻修手术死亡率更低,患者术后生活质量更高。如何在两种术式之间做出选择,需要综合考虑感染控制效果、健康效用以及费用支出等情况。本研究目的在于全面分析TKA术后PJI 的治疗措施,运用决策分析法明确最佳的治疗策略。Srivastava K Bozic KJ Silverton C 李昌钊(摘译) 李凭跃(审校) 2019中国骨科临床与基础研究杂志2019,11,1:6
15Pain and chronic pancreatitis: A complex interplay of multiple mechanisms显示文摘Despite multiple theories on the pathogenesis of pain in chronic pancreatitis,no uniform and consistently successful treatment strategy exists and abdominal pain still remains the dominating symptom for most patients and a major challenge for clinicians.Traditional theories focussed on a mechanical cause of pain related to anatomical changes and evidence of increased ductal and interstitial pressures.These observations form the basis for surgical and endoscopic drainage procedures,but the outcome is variable and often unsatisfactory.This underscores the fact that other factors must contribute to pathogenesis of pain,and has shifted the focus towards a more complex neurobiological understanding of pain generation.Amongst other explanations for pain,experimental and human studies have provided evidence that pain perception at the peripheral level and central pain processing of the nociceptive information is altered in patients with chronic pancreatitis,and resembles that seen in neuropathic and chronic pain disorders.However,pain due to e.g.,complications to the disease and adverse effects to treatment must not be overlooked as an additional source of pain.This review outlines the current theories on pain generation in chronic pancreatitis which is crucial in order to understand the complexity and limitations of current therapeutic approaches.Furthermore,it may also serve as an inspiration for further research and development of methods that can evaluate the relative contribution and interplay of different pain mechanisms in the individual patients,before they are subjected to more or less empirical treatment.Jakob Lykke Poulsen Sφren Schou Olesen Lasse Paludan Malver Jens Brφndum Frφkjr Asbjφrn Mohr Drewes 2013World Journal of Gastroenterology2013,19,42:5
