1Transarterial chemoembolization using degradable starch microspheres and iodized oil in the treatment of advanced hepatocellular carcinoma: evaluation of tumor response, toxicity, and survival显示文摘BACKGROUND: In a multidisciplinary conference patients with advanced non-resectable hepatocellular carcinoma (HCC) were stratified according to their clinical status and tumor extent to different regional modalities or to best supportive care. The present study evaluated all patients who were stratified to repeated transarterial chemoembolization (TACE) from 1999 until 2003 in terms of tumor response, toxicity, and survival. A moderate embolizing approach was chosen using a combination of degradable starch microspheres (DSM) and iodized oil (Lipiodol) in order to combine anti-tumoral efficiency and low toxicity. METHODS: Fourty-seven patients were followed up prospectively. TACE treatment consisted of cisplatin (50 mg/m2), doxorubicin (50 mg/m2), 450-900 mg DSM, and 5-30 ml Lipiodol. DSM and Lipiodol were administered according to tumor vascularization. Patient characteristics,toxicity, and complications were outlined. In multivariate regression analyses of pre-treatment variables from a prospective database, predictors for tumor response and survival after TACE were determined. RESULTS: 112 TACE courses were performed (2.4±1.5 courses per patient). Mean maximum tumor size was 75 (± 43) mm, in 68% there was bilobar disease. Best response to TACE treatment was: progressive disease (PD) 9%, stable disease (SD) 55%, partial remission (PR) 36%, and complete remission (CR) 0%. Multivariate regression analyses identified tumor size ≤75 mm, tumor number ≤5, and tumor hypervascularization as predictors for PR. The overall 1-, 2-, and 3-year-survival rates were 75%, 59%, and 41%, respectively, and the median survival was 26 months. Low α-fetoprotein levels (<400 ng/ml) (Odds ratio=3.3) and PR as best response to TACE (Odds ratio=6.7) were significantly associated with long term survival (>30 months, R2=36%). Grade 3 toxicity occurred in 7.1% (n=8), and grade 4 toxicity in 3.6% (n=4) of all courses in terms of reversible leukopenia and thrombocytopenia. The incidence of major complications was 5.4% (n=6). All complications were managed conservatively. The mortality within 6 weeks after TACE was 2.1% (one patient). CONCLUSIONS: DSM and Lipiodol were combined successfully in the palliative TACE treatment of advanced HCC resulting in high rates of tumor response and survival at limited toxicity. Favourable tumor response was associated with tumor extent and vascularization. TACE using DSM and Lipiodol can be considered a suitable palliative measure in patients who might not tolerate long acting embolizing agents.Timm D Kirchhoff Joerg S Bleck Arne Dettmer Ajay Chavan Herbert Rosenthal Sonja Merkesdal Bernd Frericks Lars Zender Nisar P Malek Tim F Greten Stefan Kubicka Michael P Manns Michael Galanski 2007Hepatobiliary & Pancreatic Diseases International2007,6,3:15
2Combination of repeated single-session percutaneous ethanol injection and transarterial chemoembolisation compared to repeated single-session percutaneous ethanol injection in patients with non-resectable hepatocellular carcinoma显示文摘瞄准:为病人评估经皮的乙醇注射(PEI ) 的治疗效果与先进, non-resectable HCC 与 transarterial chemoembolisation 的联合相比(不作声) 并且重复单个会议的 PEI,独自重复了单个会议的 PEI,重复不作声独自一个,或最好的支持的照顾。方法:在学习时期期间接受了 PEI 治疗的所有病人根据物理地位和肿瘤程度被包括并且成层到下列治疗形式之一:联合不作声并且重复单个会议的 PEI,独自重复了单个会议的 PEI,重复不作声独自一个,或最好的支持的照顾。包括Okuda分类,门静脉血栓的存在,腹水的存在,肿瘤的数字,最大的肿瘤直径,和假胆硷酯酶( CHE )的临床的参数的预示的价值,以及孩子呸上演, alpha-fetoprotein (法新社),发烧,复杂并发症的发生在这些组之间被估计并且比较。幸存用 Kaplan-Meier 被决定,多,变量回归分析。结果:所有病人的 1 年、 3 年的幸存是 73% 和 47% 。在亚群分析,联合不作声, PEI (1 ) 与更长的幸存被联系(1- , 3- , 5 年的幸存:90% , 52% ,和 43%) 与 PEI 治疗相比独自一个(2 )(1- , 3- , 5 年的幸存:65% , 50% ,和 37%) 。(3 ) 在起始的层化以后的第二等的 PEI 产出可比较的结果不作声(1- , 3- , 5 年的幸存:91% , 40% ,和 30%) 当在到最好的支持的照顾(4 ) 的层化以后的 PEI 与减少的幸存被联系时(1- , 3- , 5 年的幸存:50% , 23% , 12%) 。除了选择治疗形式,为更好的幸存的预言者是肿瘤数字(n < 5 ) ,肿瘤尺寸(< 5 厘米) ,在 PEI 前的没有腹水,和在 PEI 以后的稳定的假胆硷酯酶(P < 0.05 ) 。在在 PEI 以后的 2 wk 以内的死亡是 2.8%(n = 3 ) 。有 24 (8.9%) 主修在包括部分肝梗塞,焦点的肝坏死,和肝脓肿的 PEI 以后的复杂并发症。所有复杂并发症能非通过手术被管理。结论:重复单个会议的 PEI 在有以可接受、可管理的复杂并发症率的先进 HCC 的病人是有效的。病人们成层到联合不作声, PEI 能比那些独自成层到重复 PEI 期望更长的幸存。而且,有在好临床的地位的大或多重的肿瘤的病人可以也从联合获利不作声并且为第二等的 PEI 的再考虑。Arne Dettmer Timm D Kirchhoff Michael Gebel Lars Zender Nisar P Malek Bernhard Panning Ajay Chavan Herbert Rosenthal Stefan Kubicka Susanne Krusche Sonja Merkesdal Michael Galanski Michael P Manns Joerg S Bleck 2006World Journal of Gastroenterology2006,12,23:14
3Are there new approaches for diagnosis, therapy guidance and outcome prediction of sepsis?显示文摘Beside many efforts to improve outcome, sepsis is still one of the most frequent causes of death in critically ill patients. It is the most common condition with high mortality in intensive care units. The complexity of the septic syndrome comprises immunological aspects- i.e.,sepsis induced immunosuppression- but is not restricted to this fact in modern concepts. So far, exact mechanisms and variables determining outcome and mortality stay unclear. Since there is no typical risk profile, early diagnosis and risk stratification remain difficult, which hinders rapid and effective treatment initiation. Due to the heterogeneous nature of sepsis, potential therapy options should be adapted to the individual. Biomarkers like C-reactive protein and procalcitonin are routinely used as complementary tools in clinical decision-making. Beyond the acute phase proteins, a wide bunch of promising substances and non-laboratory tools with potential diagnostic and prognostic value is under intensive investigation. So far, clinical decision just based on biomarker assessment is not yet feasible. However, biomarkers should be considered as a complementary approach.Dubravka Kojic Benedikt H Siegler Florian Uhle Christoph Lichtenstern Peter P Nawroth Markus A Weigand Stefan Hofer Thorsten Brenner 2015World Journal of Experimental Medicine2015,5,2:14
4FibroSURE^(TM) and FibroScan~ in relation to treatment response in chronic hepatitis C virus显示文摘AIM:To compare histological endpoint assessment using noninvasive alternatives to biopsy during treatment in a chronic hepatitis C virus(HCV)cohort.METHODS:Patients with chronic HCV were randomized to receive interferon-based therapy for 24(genotypes 2/3)or 48(genotype 1)wk.FibroSURE~TM(FS)was assessed at baseline and at week-12 post-treatment follow-up.Baseline biopsy for METAVIR was assessed by a single pathologist.FibroScan~ transient elastogra-phy(TE)was performed during treatment in a patient subset.RESULTS:Two thousand and sixty patients(n = 253 in Asia)were classif ied as METAVIR F0-1(n = 1682)or F2-4(n = 378).For F2-4,FS(n = 2055)had sensitiv-ity and specif icity of 0.87 and 0.61,respectively,with area under the receiver-operating curve of 0.82;corre-sponding values for TE(n = 214)and combined FS/TE(n = 209)were 0.77,0.88 and 0.88,and 0.93,0.68 and 0.88.Overall FS/TE agreement for F2-4 was 71%(κ = 0.41)and higher in Asians vs non-Asians(κ = 0.86 vs 0.35;P < 0.001).Combined FS/TE had 97% accuracy in Asians(n = 33).Baseline FS(0.38 vs 0.51,P < 0.001)and TE(8.0 kPa vs 11.9 kPa,P = 0.006)scores were lower in patients with sustained virological response than in nonresponders,and were maintained through follow-up.CONCLUSION:FS and TE may reliably differentiate mild from moderate-advanced disease,with a potential for high diagnostic accuracy in Asians with chronic HCV.Keyur Patel Mireen Friedrich-Rust Yoav Lurie Mircea Grigorescu Carol Stanciu Chuan-Mo Lee Eugene R Schiff Dieter Hussinger Michael P Manns Guido Gerken Isabelle Colle Michael Torbenson Erik Pulkstenis G Mani Subramanian John G McHutchison Stefan Zeuzem 2011World Journal of Gastroenterology2011,17,41:4
5Prevalence of H pylori associated 'high risk gastritis' for development of gastric cancer in patients with normal endoscopic findings显示文摘AIM: To investigate the prevalence of H pylori associated corpus-predominant gastritis (CPG) or pangastritis, severe atrophy, and intestinal metaplasia (IM) in patients without any signifi cant abnormal fi ndings during upper- GI endoscopy. METHODS: Gastric biopsies from 3548 patients were obtained during upper GI-endoscopy in a 4-year period. Two biopsies from antrum and corpus were histologically assessed according to the updated Sydney-System. Eight hundred and forty-fi ve patients (mean age 54.8 ± 2.8 years) with H pylori infection and no peptic ulcer or abnormal gross fi ndings in the stomach were identifi ed and analyzed according to gastritis phenotypes using different scoring systems. RESULTS: The prevalence of severe H pylori associated changes like pangastritis, CPG, IM, and severe atrophy increased with age, reaching a level of 20% in patients of the age group over 45 years. No differences in frequencies between genders were observed. The prevalence of IM had the highest increase, being 4-fold higher at the age of 65 years versus in individuals less than 45 years. CONCLUSION: The prevalence of gastritis featuring at risk for cancer development increases with age. These findings reinforce the necessity for the histological assessment, even in subjects with normal endoscopic appearance. The age-dependent increase in prevalence of severe histopathological changes in gastric mucosa, however, does not allow estimating the individual risk forgastric cancer development-only a proper follow-up can provide this information.Andreas Leodolter Matthias P Ebert Ulrich Peitz Kathlen Wolle Stefan Kahl Michael Vieth Peter Malfertheiner 2006World Journal of Gastroenterology2006,12,34:4
6慢性继发性头痛或口面部疼痛显示文摘本文介绍了世界卫生组织(WHO)国际疾病分类-11(international classification of diseases-11,ICD-11)中有关慢性继发性头痛和慢性口面部疼痛的诊断标准,该标准主要参考国际头痛学会(InternationalHeadache Society,HIS)发布的第3版国际头痛分类标准(ICHD-3,ICD-11的神经系统疾病章节)。ICHD-3将头痛分为三大类:原发性头痛(特发性头痛)、继发性头痛(症状性头痛)和口面部疼痛(包括颅神经痛)。头痛或口面部疼痛在3个月或更长时间内有一半以上的天数发作,每天持续时间超过2个小时,应诊断为慢性头痛或慢性口面部疼痛。慢性原发性头痛和慢性原发性口面部疼痛属于慢性原发性疼痛综合征,在之前的文章中已有描述,本文仅涉及慢性继发性头痛和慢性继发性口面部疼痛。ICHD-3慢性继发性口面部疼痛次级分类中增加了颞下颌关节紊乱诊断标准和慢性牙痛的疾病分类,以及国际疼痛学会(International Association for the Study of Pain,IASP)口面部疼痛和头痛兴趣小组的贡献。本文描述的ICD-11编码将与基础疾病的编码联合使用,以识别需要疼痛管理的病人。此外,这些编码将提高此类疾病在疾病统计中的可见性,并促进对其机制的研究。于生元(编译) 何绵旺(编译) 袁文茜(编译) 曹伯旭(编译) 袁慧娟(编译) 江姣锦(编译) 别智(编译) 那伟楠(编译) 赵赫(编译) 宋学军(审校) 刘小立(审校) 万有(审校) 樊碧发(审校) 韩济生(审校) Benoliela R Svenssonb P Stefan Evers S 2021中国疼痛医学杂志2021,27,8:4
7Association of the GNAS1 T393C polymorphism with tumor stage and survival in gastric cancer显示文摘AIM:To analyze the impact of the GNAS1 T393C polymorphism on prognosis and histopathology of gastric cancer.METHODS:Genomic DNA was extracted from paraffinembedded tissues of 122 patients with primary gastric carcinoma and from the blood of 820 healthy white individuals.Allelic discrimination was performed by quantitative real-time polymerase chain reaction.Genotyping was correlated with histopathologic parameters and with overall survival according to the Kaplan-Meier approach and with multivariate analysis by multiple stepwise regression.RESULTS:Thirty-nine(32%) patients displayed a CC genotype,57(46.7%) a CT genotype and 26(21.3%) a TT genotype.The frequency of the C allele(fC) in the patient group was 0.55,which was not signif icantly different from that of healthy blood donors.The distribution was compatible with the Hardy-Weinberg equilibrium.Analysis of clinicopathological parameters did not show any signif icant correlation of the T393C genotype with gender(P=0.50),differentiation(P=0.29),pT-category(P=0.19),pN-category(P=0.30),pM-category(P=0.25),R-category(P=0.95),the classifications according to WHO(P=0.34),Laurén(P=0.16),Goseki(P=1.00) and Ming(P=0.74).Dichotomization between C+(CC+CT) and C-genotypes(TT),however,revealed signif icantly more advanced tumor stages(P=0.023) and lower survival rates(P=0.043) for C allele carriers.CONCLUSION:The present study provides strong evidence to suggest that the GNAS1 T393C allele carrier status influences tumor progression and survival in gastric cancer with higher tumor stages and a worse outcome for C allele carriers.Hakan Alakus Stefan P Mnig Ute Warnecke-Eberz Gül Alakus Günther Winde Uta Drebber Klaus J Schmitz Kurt W Schmid Kathrin Riemann Winfried Siffert Elfriede Bollschweiler Arnulf H Hlscher Ralf Metzger 2009World Journal of Gastroenterology2009,15,48:3

9Profound neutralization evasion and augmented host cell entry are hallmarks of the fast-spreading SARS-CoV-2 lineage XBB.1.5显示文摘Since late 2022, the share of infections caused by the SARS-CoV2 lineage XBB.1.5 has gradually increased in the United States,resulting in XBB.1.5 becoming the dominating SARS-CoV-2lineage in the United States and a similar trend is likely to soontake place also in European countries. However, information onthe virological properties of XBB.1.5 is scarce.

10Preparation of stable micropatterns of gold on cell-adhesion-resistant hydrogels assisted by a hetero-bifunctional macromonomer linker显示文摘Surface patterning is very useful in biomaterial studies, yet it is not easy to prepare a micropattern with cell-adhesion contrast that is stable in a wet environment. Recently, a platform technique of transfer photolithography was invented to fabricate stable metal microarrays on the surface of a cell-adhesion resistant and mechanically biomimetic poly(ethylene glycol) hydrogel; the linker is the key chemical in such a transfer strategy. This article reports the design and synthesis of a hetero-bifunctional macromonomer linker with a thiol group at one end and an acryloyl group at the other end. The bifunctional linker was characterized by GPC and 1H NMR, and the average number of thiol groups in the bifunctional linker was detected by Ellman's reagent. The regent stability under wet conditions was also confirmed by the model reactants. The resultant micropatterned surfaces are meaningful for future studies of cell behaviors on mechanically biomimetic matrixes.SUN JianGuo GRAETER Stefan V TANG Jian HUANG JingHuan LIU Peng LAI YuXiao YU Lin MAJER Günter SPATZ Joachim P DING JianDong 2014Science China Chemistry2014,57,4:2
