5AGNP精神科治疗药物监测共识指南:2011显示文摘治疗药物监测(Therapeutic drug monitoring,TDM),如通过定量测定血清或血浆药物浓度指导用药剂量优化,已经成为对患者进行精神药物治疗的很有价值的工具。在患者用药依从性难以判断、药物耐受性不佳、治疗剂量下无效以及可能存在药代动力学药物-药物相互作用等情况下,测定药物浓度是很有用的。在精神科,有可能明显获益于TDM的主要患者群体包括儿童、孕妇、老年患者、智力障碍患者、涉及司法的患者、已知或怀疑携带药代动力学相关基因变异的患者,以及合并躯体疾病影响药代动力学的患者。然而,只有将TDM充分整合到临床治疗过程中去,才能发挥其优化药物治疗的潜在优势。为了促进TDM的合理应用,神经精神药理学与药物精神病学协会(Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie,AGNP)的TDM专家组在2004年发表了精神药物治疗药物监测指南。之后,随着知识不断更新,又有许多可能需要进行TDM的新药上市。因此,本次更新将神经精神药物的种类扩展到了128种,并将其TDM必要性划分为从'强烈推荐'到'可能有用'的四个等级。经过大量细致且全面的文献检索与分门别类的汇总整理,将基于循证医学理念的'治疗参考浓度范围'和'剂量相关参考浓度范围'呈现给大家。本共识指南引入了'实验室警戒浓度'的新概念,即实验室需要马上告知治疗医生的药物浓度上限。本共识指南还给出了诸如药物作为细胞色素P450酶的底物和抑制剂的性质,代谢物与母药浓度比值的常见范围,以及与结果解释相关的内容,还提供了何时将TDM与遗传药理学检测相结合的建议。遵循本指南,有助于改善许多患者精神药物治疗的效果,特别是那些存在药代动力学异常的患者。TDM是一门交叉学科,有时针对看起来不一致的数据,需要多学科坦诚地讨论,只有这样,患者才能从这种合作中获益。Hiemke C Baumann P Bergemann N Conca A Dietmaier O Egberts K Fric M Gerlach M Greiner C Gründer G Haen E Havemann-Reinecke U Jaquenoud Sirot E Kirchherr H Laux G Lutz UC Messer T Müller MJ Pfuhlmann B Rambeck B Riederer P Schoppek B Stingl J Uhr M Ulrich S Waschgler R Zernig G 李文标(译) 果伟(译) 阮灿军(译) 贺静(译) 汤宜朗(审校) 王传跃(审校) 2016实用药物与临床2016,19,10:37

7Prognostic significance of tumor immune microenvironment and immunotherapy:Novel insights and future perspectives in gastric cancer显示文摘Despite a decrease in gastric cancer incidence, the development of novel biologic agents and combined therapeutic strategies, the prognosis of gastric cancer remains poor. Recently, the introduction of modern immunotherapy, especially using immune checkpoint inhibitors, led to an improved prognosis in many cancers. The use of immunotherapy was also associated with manageable adverse event profiles and promising results in the treatment of patients with gastric cancer, especially in heavily pretreated patients. These data have led to an accelerated approval of some checkpoint inhibitors in this setting. Understanding the complex relationship between the host immune microenvironment and tumor and the immune escape phenomenon leading to cancer occurrence and progression will subsequently lead to the identification of prognostic immune markers. Furthermore, this understanding will result in the discovery of both new mechanisms for blocking tumor immunosuppressive signals and pathways to stimulate the local immune response by targeting and modulating different subsets of immune cells. Due to the molecular heterogeneity of gastric cancers associated with differentclinico-biologic parameters, immune markers expression and prognosis, novel immunotherapy algorithms should be personalized and addressed to selected subsets of gastric tumors, which have been proven to elicit the best clinical responses. Future perspectives in the treatment of gastric cancer include tailored dual immunotherapies or a combination of immunotherapy with other targeted agents with synergistic antitumor effects.Daniela Cornelia Lazǎr Mihaela Flavia Avram Ioan Romosan Mǎrioara Cornianu Sorina Tǎan Adrian Goldis 2018World Journal of Gastroenterology2018,24,32:24

10Contribution of oxidative stress to pulmonary arterial hypertension显示文摘Recent data implicate oxidative stress as a mediator of pulmonary hypertension (PH) and of the associated pathological changes to the pulmonary vasculature and right ventricle (RV). Increases in reactive oxygen species (ROS), altered redox state, and elevated oxidant stress have been demonstrated in the lungs and RV of several animal models of PH, including chronic hypoxia, monocrotaline toxicity, caveolin-1 knock-out mouse, and the transgenic Ren2 rat which overexpresses the mouse renin gene. Generation of ROS in these models is derived mostly from the activities of the nicotinamide adenine dinucleotide phosphate oxidases, xanthine oxidase, and uncoupled endothelial nitric oxide synthase. As disease progresses circulating monocytes and bone marrow-derived monocytic progenitor cells are attracted to and accumulate in the pulmonary vasculature. Once established, these inflammatory cells generate ROS and secrete mitogenic and fibrogenic cytokines that induce cell proliferation and fibrosis in the vascular wall resulting in progressive vascular remodeling. Deficiencies in antioxidant enzymes also contribute to pulmonary hypertensive states. Current therapies were developed to improve endothelial function, reduce pulmonary artery pressure, and slow the progression of vascular remodeling in the pulmonary vasculature by targeting deficiencies in either NO (PDE-type 5 inhibition) or PGI 2 (prostacyclin analogs), or excessive synthesis of ET-1 (ET receptor blockers) with the intent to improve patient clinical status and survival. New therapies may slow disease progression to some extent, but long term management has not been achieved and mortality is still high. Although little is known concerning the effects of current pulmonary arterial hypertension treatments on RV structure and function, interest in this area is increasing. Development of therapeutic strategies that simultaneously target pathology in the pulmonary vasculature and RV may be beneficial in reducing mortality associated with RV failure.Vincent G DeMarco Adam T Whaley-Connell James R Sowers Javad Habibi Kevin C Dellsperger 2010World Journal of Cardiology2010,2,10:21

14Comprehensive and innovative techniques for livertransplantation in rats: A surgical guide显示文摘AIM: To investigate our learning curves of orthotopic liver transplantation (OLT) in rats and the most important factor for successful surgery. METHODS: We describe the surgical procedures for our rat OLT model, and determined the operator learning curves. The various factors that contributed to successful surgery were determined. The most important surgical factors were evaluated between successful and unsuccessful surgeries.RESULTS: Learning curve data indicated that 50 cases were required for operator training to start a study. Operative time, blood loss, warm ischemic time, anhepatic phase, unstable systemic hemodynamic state, and body temperature after surgery significantly affected surgery success by univariate analysis, while the anhepatic phase was the most critical factor for success by multivariate analysis. CONCLUSION: OLT in rats is the only liver transplantation model that provides clinically relevant and reliable results. Shortened anhepatic phase is key to success in this model.Tomohide Hori Justin H Nguyen Yasuhiro Ogura Toshiyuki Hata Shintaro Yagi Ann-Marie T Baine Norifumi Ohashi Christopher B Eckman Aimee R Herdt Hiroto Egawa Yasutsugu Takada Fumitaka Oike Seisuke Saka-moto Mureo Kasahara Kohei Ogawa Koichiro Hata Taku Iida Yukihide Yonekawa Lena Sibulesky Kagemasa Kuribayashi Takuma Kato Kanako Saito Mie Torii Naruhiko Sahara Naoko Kamo Tomoko Sahara Motohiko Yasutomi Shinji Uemoto 2010World Journal of Gastroenterology2010,16,25:14
15Role of PRMTs in cancer: Could minor isoforms be leaving a mark?显示文摘Protein arginine methyltransferases(PRMTs) catalyze the methylation of a variety of protein substrates, many of which have been linked to the development, progression and aggressiveness of different types of cancer. Moreover, aberrant expression of PRMTs has been observed in several cancer types. While the link between PRMTs and cancer is a relatively new area of interest, the functional implications documented thus far warrant further investigations into its therapeutic potential. However, the expression of these enzymes and the regulation of their activity in cancer are still significantly understudied. Currently there are nine main members of the PRMT family. Further, the existence of alternatively spliced isoforms for several of these family members provides an additional layer of complexity. Specifically, PRMT1, PRMT2, CARM1 and PRMT7 have been shown to have alternative isoforms and others may be currently unrealized. Our knowledge with respect to the relative expression and the specific functions of these isoforms is largely lacking and needs attention. Here we present a review of the current knowledge of theknown alternative PRMT isoforms and provide a rationale for how they may impact on cancer and represent potentially useful targets for the development of novel therapeutic strategies.R Mitchell Baldwin Alan Morettin Jocelyn C té 2014World Journal of Biological Chemistry2014,5,2:14
16EFNS的神经病理性痛药物治疗指南:2010修订显示文摘背景和目的欧洲神经病学协会联盟第2届工作组的目的是对2005年以来的关于神经病理性痛的药物治疗证据进行更新。方法使用Cochrane数据库和Medline选择相关研究,并根据病因学对研究分类。所有Ⅰ类和Ⅱ类随机对照研究(RCTs)均入选,低级别研究仅在没有高级别研究的情况下入选。考虑到对门诊患者治疗的可行性,只选择单药治疗或重复给药的研究。结果多数大型RCT的研究对象是糖尿病性多发性神经病和疱疹后神经痛的患者,越来越多的小型研究则对其他病因导致的神经病理性痛的治疗进行了探索。总体而言,药物治疗在除三叉神经痛、慢性神经根病和人类免疫缺陷病毒(HIV)神经病以外的各种病因中疗效相当,A级证据支持下列药物用于治疗神经病理性痛:三环类抗抑郁剂(TCA)、普瑞巴林、加巴喷丁、曲马多和阿片类(在不同情况下)、度洛西汀、文拉法辛、局部利多卡因和辣椒素贴剂(在限定的情况下)。联合用药有效仅见于TCA与加巴喷丁、加巴喷丁与阿片类(A级证据)。结论目前仍然缺乏大型的对比研究。我们建议今后的研究使用标准化工具对共病情况、生活质量、临床症状和体征进行评估,并致力于更好地确定对特定药物治疗的反应情况。李建萍 李颖 林智 李焰生 Attal N Cruccua G Barona R Haanpa M Hanssona P Jensena S Nurmikk T 2012神经病学与神经康复学杂志2012,9,1:14
