1中国精神卫生服务及其政策:对1949-2009年的回顾与未来10年的展望显示文摘目的:对中国1949-2009年精神卫生服务提供模式和相关政策进行了系统回顾,分析不同发展阶段的特征,为我国精神卫生改革提供借鉴。方法:通过检索电子期刊数据库和我国卫生部官方网站等数据库并配合相应的手工检索,纳入收集整理与精神疾病流行病学、精神卫生服务提供、精神卫生服务利用、精神卫生政策和规划高度相关的资料。访谈国内外从事精神卫生服务工作的多名知名专家和主管领导,对其访谈内容记录、录音,进行归纳、分析、总结。结果:共纳入216篇文献,213人参与访谈。研究显示,60年来中国精神卫生资源和服务模式的演变经历了快速发展、稳步发展和改革等三个阶段;中国精神卫生服务体系在60年间发生了巨变化,但仍存在资源短缺、精神病治疗率较低、普通人群和医务人员精神卫生知识匮乏、社会对精神病人的偏见严重等现状;60年间,中国精神卫生服务政策也经历了巨大的变化,正向着建立以社区精神卫生服务为主的综合服务网络方向前进。结论:我国应继续强化社区卫生服务,提高精神卫生服务的公平性和可及性。栗克清 孙秀丽 张勇 石光 Arnulf KOLSTAD 2012中国心理卫生杂志2012,26,5:38
2Deep Learning-Based Numerical Methods for High-Dimensional Parabolic Partial Differential Equations and Backward Stochastic Differential Equations显示文摘We study a new algorithm for solvingparabolic partial differential equations(PDEs)and backward stochastic differential equations(BSDEs)in high dimension,which is based on an analogy between the BSDE and reinforcement learning with the gradient of the solution playing the role of the policy function,and the loss function given by the error between the prescribed terminal condition and the solution of the BSDE.The policy function is then approximated by a neural network,as is done in deep reinforcement learning.Numerical results using TensorFlow illustrate the efficiency and accuracy of the studied algorithm for several 100-dimensional nonlinear PDEs from physics and finance such as the Allen–Cahn equation,the Hamilton–Jacobi–Bellman equation,and a nonlinear pricing model for financial derivatives.Weinan E Jiequn Han Arnulf Jentzen 2017Communications in Mathematics and Statistics2017,5,4:20
3Co-expression of CDX2 and MUC2 in gastric carcinomas: Correlations with clinico-pathological parameters and prognosis显示文摘AIM: To evaluate the role of CDX2 homeobox protein as a predictor for cancer progression and prognosis as well as its correlation with MUC2 expression. CDX2 represents a transcription factor for various intestinal genes (including MUC2) and thus an important regulator of intestinal differentiation, which could previously be identified in gastric carcinomas and intestinal metaplasia.METHODS: Formalin-fixed and paraffin-embedded tissues from 190 gastric carcinoma patients were stained with monodonal antibodies recognizing CDX2 and MUC2, respectively. Immunoreactivity was evaluated semiquantitatively and statistical analyses including χ2 tests, uni- and multi-variate survival analyses were performed.RESULTS: CDX2 was mostly expressed in a nuclear or supranuclear pattern, whereas MUC2 showed an almost exclusive supranuclear reactivity. Both antigens were present in >80% of areas exhibiting intestinal metaplasia. An immunoreactivity in >5% of the tumor area was observed in 57% (CDX2) or in 21% (MUC2) of the carcinomas. The presence of both molecules did not correlate with WHO,significantly stronger vlUC2 expression in mucinous tumors). CDX2 correlated with a lower pT and pN stage in the subgroups of intestinal and stage I cancers and was associated with MUC2 positivity. A prognostic impact of CDX2 or MUC2 was not observed. CONCLUSION: CDX2 and MUC2 play an important role in the differentiation of normal, inflamed, and neoplastic gastric tissues. According to our results, loss of CDX2 may represent a marker of tumor progression in early gastric cancer and carcinomas with an intestinal phenotype.Kristina Roessler Stefan P.M(o|¨)nig Paul M.Schneider Franz-Georg Hanisch Stephanie Landsberg Juergen Thiele Arnulf H.H(o|¨)lscher Hans P.Dienes Stephan E.Baldus 2005World Journal of Gastroenterology2005,11,21:15
4Treatment of early gastric cancer in the Western World显示文摘The incidence rate of gastric cancer is much higher in Asia than in the Western industrial nations.According to the different screening programs in Japan and Korea about fifty percent of treated patients had an early tumor stage.In contrast,European and American patients with gastric cancer had an advanced tumor stage.Therefore,the experience for the various therapeutic options for gastric cancer may be different between these regions.In this review we tried to point out the treatment modalities in Western industrial countries for early gastric cancer.Elfriede Bollschweiler Felix Berlth Christoph Baltin Stefan Mnig Arnulf H Hlscher 2014World Journal of Gastroenterology2014,20,19:8
5Regional lymphadenectomy strongly recommended in T1b gallbladder cancer显示文摘This article discusses the adequate treatment of early gallbladder cancer(T1a,T1b) and is based on published studies extending over nearly 3 decades.Randomized studies and meta analyses comparing different surgical treatments do not exist.The literature shows that in up to 20% of patients lymph node metastasis are found in T1b gallbladder cancer.Due to high malignancy with early angiolymphatic spread and resistance to chemotherapy and radiation on the one hand,and the relative low operative risk of extended cholecystectomy(cholecystectomy and regional lymphadenectomy) on the other hand,we believe that this procedure is mandatory in early gallbladder cancer.Ulrich Klaus Fetzner Arnulf H Hlscher Dirk L Stippel 2011World Journal of Gastroenterology2011,17,38:8
6Pathohistological classification systems in gastric cancer:Diagnostic relevance and prognostic value显示文摘Several pathohistological classification systems exist for the diagnosis of gastric cancer.Many studies have investigated the correlation between the pathohistological characteristics in gastric cancer and patient characteristics,disease specific criteria and overall outcome.It is still controversial as to which classification system imparts the most reliable information,and therefore,the choice of system may vary in clinical routine.In addition to the most common classification systems,such as the Laurén and the World Health Organization(WHO)classifications,other authors have tried to characterize and classify gastric cancer based on the microscopic morphology and in reference to the clinical outcome of the patients.In more than 50 years of systematic classification of the pathohistological characteristics of gastric cancer,there is no sole classification system that is consistently used worldwide in diagnostics and research.However,several national guidelines for the treatment of gastric cancer refer to the Laurén or the WHO classifications regarding therapeutic decision-making,which underlines the importance of a reliable classification system for gastric cancer.The latest results from gastric cancer studies indicate that it might be useful to integrate DNA-and RNA-based features of gastric cancer into the classification systems to establish prognostic relevance.This article reviews the diagnostic relevance and the prognostic value of different pathohistological classification systems in gastric cancer.Felix Berlth Elfriede Bollschweiler Uta Drebber Arnulf H Hoelscher Stefan Moenig 2014World Journal of Gastroenterology2014,20,19:6

9Neoadjuvant treatment for advanced esophageal cancer: response assessment before surgery and how to predict response to chemoradiation before starting treatment显示文摘Patients with advanced esophageal cancer(T3-4, N) have a poor prognosis. Chemoradiation or chemotherapy before esophagectomy with adequate lymphadenectomy is the standard treatment for patients with resectable advanced esophageal carcinoma. However, only patients with major histopathologic response(regression to less than 10% of the primary tumor) after preoperative treatment will have a prognostic benefit of preoperative chemoradiation. Using current therapy regimens about 40% to 50% of the patients show major histopathological response. The remaining cohort does not benefit from this neoadjuvant approach but might benefit from earlier surgical resection. Therefore, it is an aim to develop tools for response prediction before starting the treatment and for early response assessment identifying responders. The current review discusses the different imaging techniques and the most recent studies about molecular markers for early response prediction. The results show that [18F]-fluorodeoxyglucose-positron emission tomography(FDGPET) has a good sensitivity but the specificity is not robust enough for routine clinical use. Newer positron emission tomography detector technology, the combination of FDG-PET with computed tomography, additional evaluation criteria and standardization of evaluation may improve the predictive value. There exist a great number of retrospective studies using molecular markers for prediction of response. Until now the clinical use is missing. But the results of first prospective studies are promising. A future perspective may be the combination of imaging technics and special molecular markers for individualized therapy. Another aspect is the response assessment after finishing neoadjuvant treatment protocol. The different clinical methods are discussed. The results show that until now no non-invasive method is valid enough to assess complete histopathological response.Elfriede Bollschweiler Arnulf H.Hlscher Matthias Schmidt Ute Warnecke-Eberz 2015Chinese Journal of Cancer Research2015,27,3:3

11Association 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

14Simultaneous occurrence of a hepatocellular carcinoma and a hepatic non-Hodgkin's lymphoma infi ltration显示文摘To investigate the simultaneous occurrence of hepatocellular carcinoma and non-Hodgkin's lymphoma, we report the case of a 70 year old patient with a primary diagnosis of non-Hodgkin's lymphoma in 2002. In a routine follow up investigation of his chronic lymphocytic leukemia a newly detected mass in the Couinaud's segments 2 and 3 was found. No hepatitis C virus or hepatitis B virus infection or cirrhosis was evident. After laparoscopic segmentectomy the histological examination revealed a hepatocellular carcinoma. While the relation between liver parenchyma damages and hepatocellular carcinoma or non-Hodgkin's lymphoma is well known, only a few publications have focused on the coexistence of hepatocellular carcinoma and non-Hodgkin's lymphoma. With this case we demonstrate the coexistence of these diseases without having a pre- damaged liver parenchyma.Sabine Heidecke Dirk L Stippel Arnulf H Hoelscher Inga Wedemeyer Hans-Peter Dienes Uta Drebber 2010World Journal of Hepatology2010,2,6:2
