1AGNP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
2Autoimmune hepatitis,one disease with many faces:Etiopathogenetic,clinico-laboratory and histological characteristics显示文摘Autoimmune hepatitis(AIH) is an unresolving progressive liver disease of unknown etiology characterized byhypergammaglobulinemia,autoantibodies detection and interface hepatitis.Due to the absence of specific diagnostic markers and the large heterogeneity of its clinical,laboratory and histological features,AIH diagnosis may be potentially difficult.Therefore,in this in-depth review we summarize the substantial progress on etiopathogenesis,clinical,serological and histological phenotypes of AIH.AIH has a global distribution affecting any age,both sexes and all ethnic groups.Clinical manifestations vary from asymptomatic to severe or rarely fulminant hepatitis.Hypergammaglobulinemia with selective elevation of IgG is found in most cases.Autoimmune attack is perpetuated,possibly via molecular mimicry,and favored by the impaired control of T-regulatory cells.Histology(interface hepatitis,emperipolesis and hepatic rosette formation) and autoantibodies detection although not pathognomonic,are still the hallmark for a timely diagnosis.AIH remains a major diagnostic challenge.AIH should be considered in every case in the absence of viral,metabolic,genetic and toxic etiology of chronic or acute hepatitis.Laboratory personnel,hepato-pathologists and clinicians need to become more familiar with disease expressions and the interpretation of liver histology and autoimmune serology to derive maximum benefit for the patient.Nikolaos K Gatselis Kalliopi Zachou George K Koukoulis George N Dalekos 2015World Journal of Gastroenterology2015,21,1:36

6Advancedendoscopicsubmucosaldissectionwithtraction显示文摘Endoscopic submucosal dissection (ESD) has been established as a standard treatment for early stage gastric cancer (EGC) in Japan and has spread worldwide. ESD has been used not only for EGC but also for early esophageal and colonic cancers. However, ESD is as-sociated with several adverse events, such as bleeding and perforation, which requires more skill. Adequate tissue tension and clear visibility of the tissue to be dissected are important for effective and safe dissection. Many ESD methods using traction have been devel-oped, such as clip-with-line method, percutaneous trac-tion method, sinker-assisted method, magnetic anchor method, external forceps method, internal-traction method, double-channel-scope method, outerroute method, double-scope method, endoscopic-surgical-platform, and robot-assisted method. Each method has both advantages and disadvantages. Robotic endos-copy, enabling ESD with a traction method, will become more common due to advances in technology. In thenear future, simple, noninvasive, and effective ESD us-ing traction is expected to be developed and become established as a worldwide standard treatment for superficial gastrointestinal neoplasias.Imaeda H Hosoe N Kashiwagi K Ohmori T Yahagi N Kanai T Ogata H 2014World Journal of Gastrointestinal Endoscopy2014,6,7:24

8Golgi protein-73:A biomarker for assessing cirrhosis and prognosis of liver disease patients显示文摘BACKGROUND Reliable biomarkers of cirrhosis,hepatocellular carcinoma(HCC),or progression of chronic liver diseases are missing.In this context,Golgi protein-73(GP73)also called Golgi phosphoprotein-2,was originally defined as a resident Golgi type II transmembrane protein expressed in epithelial cells.As a result,GP73 expression was found primarily in biliary epithelial cells,with only slight detection in hepatocytes.However,in patients with acute or chronic liver diseases and especially in HCC,the expression of GP73 is significantly up-regulated in hepatocytes.So far,few studies have assessed GP73 as a diagnostic or prognostic marker of liver fibrosis and disease progression.AIM To assess serum GP73 efficacy as a diagnostic marker of cirrhosis and/or HCC or as predictor of liver disease progression.METHODS GP73 serum levels were retrospectively determined by a novel GP73 ELISA(QUANTA Lite®GP73,Inova Diagnostics,Inc.,Research Use Only)in a large cohort of 632 consecutive patients with chronic viral and non-viral liver diseases collected from two tertiary Academic centers in Larissa,Greece(n=366)and Debrecen,Hungary(n=266).Aspartate aminotransferase(AST)/Platelets(PLT)ratio index(APRI)was also calculated at the relevant time points in all patients.Two hundred and three patients had chronic hepatitis B,183 chronic hepatitis C,198 alcoholic liver disease,28 autoimmune cholestatic liver diseases,15 autoimmune hepatitis,and 5 with other liver-related disorders.The duration of follow-up was 50(57)mo[median(interquartile range)].The development of cirrhosis,liver decompensation and/or HCC during follow-up were assessed according to internationally accepted guidelines.In particular,the surveillance for the development of HCC was performed regularly with ultrasound imaging and alpha-fetoprotein(AFP)determination every 6 mo in cirrhotic and every 12 mo in non-cirrhotic patients.RESULTS Increased serum levels of GP73(>20 units)were detected at initial evaluation in 277 out of 632 patients(43.8%).GP73-seropositivity correlated at baseline with the presence of cirrhosis(96.4%vs 51.5%,P<0.001),decompensation of cirrhosis(60.3%vs 35.5%,P<0.001),presence of HCC(18.4%vs 7.9%,P<0.001)and advanced HCC stage(52.9%vs 14.8%,P=0.002).GP73 had higher diagnostic accuracy for the presence of cirrhosis compared to APRI score[Area under the curve(AUC)(95%CI):0.909(0.885-0.934)vs 0.849(0.813-0.886),P=0.003].Combination of GP73 with APRI improved further the accuracy(AUC:0.925)compared to GP73(AUC:0.909,P=0.005)or APRI alone(AUC:0.849,P<0.001).GP73 levels were significantly higher in HCC patients compared to non-HCC[22.5(29.2)vs 16(20.3)units,P<0.001)and positively associated with BCLC stage[stage 0:13.9(10.8);stage A:17.1(16.8);stage B:19.6(22.3);stage C:32.2(30.8);stage D:45.3(86.6)units,P<0.001]and tumor dimensions[very early:13.9(10.8);intermediate:19.6(18.4);advanced:29.1(33.6)units,P=0.004].However,the discriminative ability for HCC diagnosis was relatively low[AUC(95%CI):0.623(0.570-0.675)].Kaplan-Meier analysis showed that the detection of GP73 in patients with compensated cirrhosis at baseline,was prognostic of higher rates of decompensation(P=0.036),HCC development(P=0.08),and liver-related deaths(P<0.001)during follow-up.CONCLUSION GP73 alone appears efficient for detecting cirrhosis and superior to APRI determination.In combination with APRI,its diagnostic performance can be further improved.Most importantly,the simple GP73 measurement proved promising for predicting a worse outcome of patients with both viral and nonviral chronic liver diseases.Nikolaos K Gatselis Tamás Tornai Zakera Shums Kalliopi Zachou Asterios Saitis Stella Gabeta Roger Albesa Gary L Norman Mária Papp George N Dalekos 2020World Journal of Gastroenterology2020,26,34:21
9世界卫生组织(WHO)造血与淋巴组织肿瘤分类方案:临床顾问委员会会议报告显示文摘引言 :从 1995年开始 ,欧洲病理学工作者协会和血液病理学会一直致力于制定一个新的世界卫生组织 (WHO)血液恶性肿瘤分类方案 ,该分类方案包括淋巴系肿瘤、髓系肿瘤、组织细胞肿瘤和肥大细胞肿瘤。 材料与方法 :此项 WHO计划共组成十个病理学工作者委员会 ,负责确定病种和作出定义。另外还成立一个由国际血液学家和肿瘤学家组成的临床顾问委员会 (CAC)以保证该分类的临床实用性。 1997年 11月召开会议讨论了与该分类有关的临床问题。 结果 :WHO采纳了 1994年国际淋巴瘤研究组 (IL SG)报告的修订欧美淋巴系肿瘤分类 (REAL)方案作为淋巴系肿瘤的分类方案。该方案的分类方法遵循以下原则 :分类应是联合应用形态学、免疫表型、遗传特征及临床特征能够清楚界定的“真实存在”(“real”)病种的名录 ,上述各项特征的相对重要性因病种不同而异 ,不存在任何“金标准”。 WHO将 REAL分类原则延用于髓系肿瘤和组织细胞肿瘤 ,髓系肿瘤的分类包括联合应用细胞形态学和细胞遗传学异常能够界定的各个病种。围绕一系列临床问题召集的这次 CAC会议 ,就提交的大多数问题达成共识 ,这些问题及共识将详述于下。对于另外一些问题 ,CAC认为淋巴系肿瘤临床分组既无必要也不必需 ,患者的治疗取决于淋巴瘤的具体类型 ,如有?N L Harris E S Jaffe J Diebold G Flandrin H K Muller-Hermelink J Vardiman T A Lister C D Bloomfield 张凤奎 郝玉书 2001白血病.淋巴瘤2001,10,3:20
10Larvicidal and repellent potential of Moringa oleifera against malarial vector,Anopheles stephensi Liston(Insecta:Diptera:Culicidae)显示文摘Objective:To evaluate the larvicidal and pupicidal potential of the methanolic extracts from Moringa oleifera(M.oleifera) plant seeds against malarial vector Anopheles stephensi(A.stephensi) mosquitoes at different concentrations(20,40,60,80 and 100 ppm).Methods:M.oleifera was collected from the area of around Bharathiar University,Coimbatore.The dried plant materials were powdered by an electrical blender.From each sample,100 g of the plant material were extracted with 300 mL of methanol for 8 h in a Soxhlet apparatus.The extracts were evaporated to dryness in rotary vacuum evaporator to yield 122 mg and 110 mg of dark greenish material(residue) from Arcang amara and Ocimum basilicum,respectively.One gram of the each plant residue was dissolved separately in 100 mL of acetone(stock solution) from which different concentrations, i.e.,20,40,60,80 and 100 ppm were prepared.Results:Larvicidal activity of M.oleifera exhibited in the first to fourth instar larvae of the A.stephensi,and the LC_(50) and LC_(90) values were 57.79 ppm and 125.93 ppm for the first instar,63.90 ppm and 133.07 ppm for the second inslar,72.45 ppm and 139.82 ppm for the third instar,78.93 ppm and 143.20 ppm for the fourth instar,respectively. During the pupal stage the methanolic extract of M.oleifera showed that the LC_(50),and LC_(90) values were 67.77 ppm and 141.00 ppm,respectively.Conclusions:The present study indicates that the phytochemicals derived from M.oleifera seeds extracts are effective mosquito vector control agents and the plant extracts may be used for further integrated pest management programs.Prabhu K Murugan K Nareshkumar A Ramasubramanian N Bragadeeswaran S 2011Asian Pacific Journal of Tropical Biomedicine2011,1,2:19

12时效对SnAgCu/SnAgCu-TiO_2焊点界面与性能影响显示文摘研究了SnAgCu与SnAgCu-TiO2两种无铅钎料与铜基板之间的界面反应,研究其在140℃时效过程中的生长行为及力学性能变化.结果表明,焊后两种钎料对应界面层为Cu6Sn5相,经过140℃时效,界面层厚度随着时效时间的增加而增加.发现金属间化合物层厚度和时效时间的平方根成正比例关系.当时效时间为300 h时,界面层出现Cu3Sn相,发现纳米TiO2颗粒对界面金属间化合物层厚度有明显的抑制作用.同时对焊点力学性能分析,在时效过程中焊点平均拉伸力明显下降,SnAgCu-TiO2焊点的力学性能明显优于SnAgCu焊点.张亮 Tu K N 郭永环 何成文 张剑 2013焊接学报2013,34,8:17
13Intrahepatic biliary cystic neoplasms:Surgical results of 9 patients and literature review显示文摘AIM: To investigate the eligible management of the cystic neplasms of the liver. METHODS: The charts of 9 patients who underwent surgery for intrahepatic biliary cystic liver neoplasms between 2003 and 2008 were reviewed retrospectively. Informed consent was obtained from the patients and approval was obtained from the designated review board of the institution. RESULTS: All patients were female with a median (range) age of 49 (27-60 years). The most frequent symptom was abdominal pain in 6 of the patients. Four patients had undergone previous laparotomy (with other diagnoses) which resulted in incomplete surgery or recurrences. Liver resection (n = 6) or enucleation (n = 3) was performed. The final diagnosis was intrahepaticbiliary cystadenoma in 8 patients and cystadenocarcinoma in 1 patient. All symptoms resolved after surgery. There has been no recurrence during a median (range) 31 (7-72) mo of follow up. CONCLUSION: In spite of the improvement in imaging modalities and increasing recognition of biliary cystadenoma and cystadenocarcinoma, accurate preoperative diagnosis may be difficult. Complete surgical removal (liver resection or enucleation) of these lesions yields satisfying long-term results.Ali Emre Kür■at Rahmi Serin Ilgin zden Yaman Tekant Orhan Bilge Ayd■n Alper Mine Güllüoglu Koray Güven 2011World Journal of Gastroenterology2011,17,3:15
14Pulmonary involvement in inflammatory bowel disease显示文摘AIM:To determine the relationship of pulmonary abnormalities and bowel disease activity in inflammatory bowel disease(IBD).METHODS:Thirty ulcerative colitis(UC)and nine Crohn's disease patients,and 20 control subjects were enrolled in this prospective study.Detailed clinical information was obtained.Extent and activity of the bowel disease were established endoscopically.Each patient underwent pulmonary function tests and high-resolution computed tomography(HRCT).Blood samples for measurement of C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),angiotensin converting enzyme and total IgE were delivered by the patients.RESULTS:Ten(25.6%)patients had respiratory symptoms.A pulmonary function abnormality was present in 22 of 39 patients.Among all patients,the most prevalent abnormalities in lung functions were a decrease in forced expiratory volume in 1 s(FEV1),FEV1/forced vital capacity(FVC),forced expiratory flow(FEF)25%-75%,transfer coefficient for carbon monoxide(DLCO),DLCO/alveolar volume.Increased respiratory symptoms score was associated with high endoscopic activity index in UC patients.Endoscopic and clinical activities in UC patients were correlated with FEV1,FEV1/FVC,and FEF 25%-75%.Smoking status,duration of disease and medication were not correlated with pulmonary physiological test results,HRCT abnormalities,clinical/endoscopic disease activity,CRP,ESR or total IgE level or body mass index.CONCLUSION:It is important that respiratory manifestations are recognized and treated early in IBD.Otherwise,they can lead to destructive and irreversible changes in the airway wall.Aydin Yilmaz Nilgün Yilmaz Demirci Derya Hosgün Enver ner Yurdanur Erdogan Atila Gkek Atalay aglar 2010World Journal of Gastroenterology2010,16,39:15

20Factors associated with time to laparoscopic cholecystectomy for acute cholecystitis显示文摘AIM: To determine patient and process of care factors associated with performance of timely laparoscopic cholecystectomy for acute cholecystitis. METHODS: A retrospective medical record review of 88 consecutive patients with acute cholecystitis was conducted. Data collected included demographic data, co-morbidities, symptoms and physical findings at presentation, laboratory and radiological investigations, length of stay, complications, and admission service (medical or surgical). Patients not undergoing cholecystectomy during this hospitalization were excluded from analysis. Hierarchical generalized linear models were constructed to assess the association of pre-operative diagnostic procedures, presenting signs, and admitting service with time to surgery.RESULTS: Seventy cases met inclusion and exclusion criteria, among which 12 were admitted to the medical service and 58 to the surgical service. Mean ± SD time to surgery was 39.3 ± 43 h, with 87% of operations performed within 72 h of hospital arrival. In the adjusted models, longer time to surgery was associated with number of diagnostic studies and endoscopic retrograde cholangio-pancreatography (ERCP, P = 0.01) as well with admission to medical service without adjustment for ERCP (P < 0.05). Patients undergoing both magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT) scans experienced the longest waits for surgery. Patients admitted to the surgical versus medical service underwent surgery earlier (30.4 ± 34.9 vs 82.7 ± 55.1 h, P < 0.01), had less post-operative complications (12% vs 58%, P < 0.01), and shorter length of stay (4.3 ± 3.4 vs 8.1 ± 5.2 d, P < 0.01).CONCLUSION: Admission to the medical service and performance of numerous diagnostic procedures, ERCP, or MRCP combined with CT scan were associated with longer time to surgery. Expeditious performance of ERCP and MRCP and admission of medically stable patients with suspected cholecystitis to the surgical service to speed up time to surgery should be considered.Chris N Daniak David Peretz Jonathan M Fine Yun Wang Alan K Meinke William B Hale 2008World Journal of Gastroenterology2008,14,7:13
