2原发性颅内淋巴瘤分型及治疗显示文摘 原发性脑淋巴瘤(primary lymphoma of the brain,PLB)是一种较罕见的中枢神经系统恶性肿瘤,约占颅内原发性肿瘤0.3%~1.5%,占全身淋巴瘤1%以下,不向中枢神经系统轴以外播散,生物学行为具有侵袭性,病理形态存在异质性.李明洙 罗力 高乃康 富春雨 窦长武 王涛 李云霞 2006中华神经外科杂志2006,22,4:30
3New ultrasound techniques for lymph node evaluation显示文摘Conventional ultrasound(US)is the recommended imaging method for lymph node(LN)diseases with the advantages of high resolution,real time evaluation and relative low costs.Current indications of transcutaneous ultrasound and endoscopic ultrasound include the detection and characterization of lymph nodes and the guidance for LN biopsy.Recent advances in US technology,such as contrast enhanced ultrasound(CEUS),contrast enhanced endoscopic ultrasound(CE-EUS),and real time elastography show potential to improve the accuracy of US for the differential diagnosis of benign and malignant lymph nodes.In addition,CEUS and CE-EUS have been also used for the guidance of fine needle aspiration and assessment of treatment response.Complementary to size criteria,CEUS could also be used to evaluate response of tumor angiogenesis to anti-angiogenic therapies.In this paper we review current literature regarding evaluation of lymphadenopathy by new and innovative US techniques.Xin-Wu Cui Christian Jenssen Adrian Saftoiu Andre Ignee Christoph F Dietrich 2013World Journal of Gastroenterology2013,19,30:25
4Impaired PI3K/Akt signal pathway and hepatocellular injury in high-fat fed rats显示文摘AIM:To determine whether mitochondrial dysfunction resulting from high-fat diet is related to impairment of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt,also known as PKB) pathway. METHODS:Rat models of nonalcoholic fatty liver were established by high-fat diet feeding. The expression of total and phosphorylated P13K and Akt proteins in hepatocytes was determined by Western blotting. Degree of fat accumulation in liver was measured by hepatic triglyceride. Mitochondrial number and size were determined using quantitative morphometric analysis under transmission electron microscope. The permeability of the outer mitochondrial membrane was assessed by determining the potential gradient across this membrane.RESULTS:After Wistar rats were fed with high-fat diet for 16 wk,their hepatocytes displayed an accumulation of fat (103.1 ± 12.6 vs 421.5 ± 19.7,P < 0.01),deformed mitochondria (9.0% ± 4.3% vs 83.0% ± 10.9%,P < 0.05),and a reduction in the mitochondrial membrane potential (389.385% ± 18.612% vs 249.121% ± 13.526%,P < 0.05). In addition,the expression of the phosphorylated P13K and Akt proteins in hepatocytes was reduced,as was the expression of the anti-apoptotic protein Bcl-2,while expression of the pro-apoptotic protein caspase-3 was increased. When animals were treated with pharmacological inhibitors of P13K or Akt,instead of high-fat diet,a similar pattern of hepatocellular fat accumulation,mitochondrial impairment,and change in the levels of PI3K,Akt,Bcl-2 was observed. CONCLUSION:High-fat diet appears to inhibit the PI3K/Akt signaling pathway,which may lead to hepa-tocellular injury through activation of the mitochondrial membrane pathway of apoptosis.Ji-Wu Han,Department of Gastroenterology,The 4th Hospital of Harbin Medical University,Harbin 150001,Heilongjiang Province,China Xiao-Rong Zhan,Xin-Yu Li,Bing Xia,Yue-Ying Wang,Jing Zhang,Department of Endocrinology,First Hospital of Harbin Medical University,Harbin 150001,Heilongjiang Province,China Bao-Xin Li,Department of Pharmacology,State Key Laboratory of Biomedicine and Pharmacology,Harbin Medical University,Harbin 150001,Heilongjiang Province,China 2010World Journal of Gastroenterology2010,16,48:22
5Gastric low-grade mucosal-associated lymphoid tissue-lymphoma: Helicobacter pylori and beyond显示文摘The stomach is the most frequently involved site for extranodal lymphomas,accounting for nearly two-thirds of all gastrointestinal cases.It is widely accepted that gastric B-cell,low-grade mucosal-associated lymphoid tissue(MALT)-lymphoma is caused by Helicobacter pylori(H.pylori)infection.MALT-lymphomas may engender different clinical and endoscopic patterns.Often,diagnosis is confirmed in patients with only vague dyspeptic symptoms and without macroscopic lesions on gastric mucosa.H.pylori eradication leads to lymphoma remission in a large number of patients when treatment occurs at an early stage(Ⅰ-Ⅱ1).Neoplasia confined to the submucosa,localized in the antral region of the stomach,and without API2-MALT1 translocation,shows a high probability of remission following H.pylori eradication.When both bacterial infection and lymphoma recur,further eradication therapy is generally effective.Radiotherapy,chemotherapy and,in selected cases,surgery are the available therapeutic options with a high success rate for those patients who fail to achieve remission,while data on immunotherapy with monoclonal antibodies (rituximab)are still scarce.The 5-year survival rate is higher than 90%,but careful,long-term follow-up is required in these patients since lymphoma recurrence has been reported in some cases.Angelo Zullo Cesare Hassan Francesca Cristofari Francesco Perri Sergio Morini 2010World Journal of Gastrointestinal Oncology2010,2,4:21

10Primary colorectal lymphoma:An overview显示文摘Lymphomas represent common hematological malignancies with increasing incidence in recent years.The major site of extranodal non-Hodgkin lymphoma is the gastrointestinal tract.Involvement of the large intestine is rare in comparison to the stomach or small bowel.The disease appears later in life,predominantly in the male population.Complaints are nonspecific,requiring a high index of suspicion in order to establish the diagnosis.The treatment varies from chemotherapy alone to multimodal therapies combining surgery,chemotherapy and radiotherapy.The small number of patients with various histological subtypes and different stage at presentation results in unclear protocol for the treatment of primary colorectal lymphoma.The purpose of this paper is to review current data on primary lymphoma of the colon and rectum while analyzing reported case series and published material on the subject.Goran Z Stanojevic Milica D Nestorovic Branko R Brankovic Miroslav P Stojanovic Milan M Jovanovic Milan D Radojkovic 2011World Journal of Gastrointestinal Oncology2011,3,1:15

13Laparoscopic splenectomy:Current concepts显示文摘Since early 1990's,when it was inaugurally introduced,laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications.Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen.However some contraindications still apply.The evolution of the technology has allowed though,cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches.Moreover,the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications.Today,laparoscopic splenectomy is considered safe,with better outcomes in comparison to open splenectomy,and the increased experience of surgeons allows operative times comparable to those of an open splenectomy.In this review we discuss the indications and the contraindications of laparoscopic splenectomy.Moreover we analyze the standard and modified surgical approaches,and we evaluate the short-term and long-term outcomes.Evangelos P Misiakos George Bagias Theodore Liakakos Anastasios Machairas 2017World Journal of Gastrointestinal Endoscopy2017,9,9:14

16Review of the current targeted therapies for non-small-cell lung cancer显示文摘The last decade has witnessed the development of oncogene-directed targeted therapies that have significantly changed the treatment of non-small-cell lung cancer(NSCLC). In this paper we review the data demonstrating efficacy of gefitinib, erlotinib, and afatinib, which target the epidermal growth factor receptor(EGFR), and crizotinib which targets anaplastic lymphoma kinase(ALK). We discuss the challenge of acquired resistance to these small-molecular tyrosine kinase inhibitors and review promising agents which may overcome resistance, including the EGFR T790 Mtargeted agents CO-1686 and AZD9291, and the ALKtargeted agents ceritinib(LDK378), AP26113, alectinib(CH/RO5424802), and others. Emerging therapies directed against other driver oncogenes in NSCLC including ROS1, HER2, and BRAF are covered as well. The identification of specific molecular targets in a significant fraction of NSCLC has led to the personalized deployment of many effective targeted therapies, with more to come.Kim-Son H Nguyen Joel W Neal Heather Wakelee 2014World Journal of Clinical Oncology2014,5,4:13

18Expression and clinical value of programmed cell death-ligand 1(PD-L1)in diffuse large B cell lymphoma:a retrospective study显示文摘Background: The programmed cell death-1(PD-1)/programmed cell death-ligand 1(PD-L1) pathway inhibits the activation of T cells and plays a crucial role in the negative regulation of cellular and humoral immune responses.Diffuse large B-cell lymphoma(DLBCL) is the most common lymphoid malignancy in adults. In the present study, we aimed to detect the expression of PD-L1 in DLBCL and to analyze its relationship with prognosis.Methods: We reviewed medical records of 204 newly diagnosed DLBCL patients in Sun Yat-sen University Cancer Center between October 2005 and August 2012. The expression of PD-L1 in tumor tissues from these 204 patients was detected using immunohistochemical(IHC) assay. The expression of anaplastic lymphoma kinase(ALK), CD5,CD30, and C-Myc in tumor specimens from 109 patients was detected using IHC, and Epstein-Barr virus(EBV)-encoded RNAs(EBERs) were detected using fluorescence in situ hybridization. The Spearman method was used for correlation analysis. The Kaplan-Meier method with log-rank test was used for univariate analysis. Cox proportional hazards model was used for multivariate analysis.Results: Of the 204 patients, 100(49.0%) were PD-L1-positive in tumor cells and 44(21.6%) were PD-L1-positive in tumor microenvironment. PD-L1 expression in tumor cells and tumor microenvironment were more common in the non-germinal center B-cell-like(GCB) subtype than in the GCB subtype(P = 0.02 and P= 0.04). Patients with PD-L1 expression in tumor microenvironment were more likely to be resistant to first-line chemotherapy when compared with the patients without PD-L1 expression in tumor microenvironment(P = 0.03). PD-L1 expression in tumor microenvironment was negatively correlated with C-Myc expression(r =-0.20, P = 0.04). No correlations were detected between PD-L1 expression and the expression of ALK, CD5, and CD30 as well as EBERs. The 5-year overall survival(OS)rates were 50.0% and 67.3% in patients with and without PD-L1 expression in tumor cells(P = 0.02). PD-L1 expression in tumor cells was an independent risk predictor for OS(P < 0.01).Conclusions: PD-L1 expression is more common in the non-GCB subtype than in the GCB subtype. PD-L1 expression in tumor microenvironment has a negative correlation with C-Myc. PD-L1 positivity predicts short survival in DLBCL patients. For patients with PD-L1 expression, more strategy such as anti-PD-L1 antibody treatment should be recommended.Li-Yang Hu Xiao-Lu Xu Hui-Lan Rao Jie Chen Ren-Chun Lai Hui-Qiang Huang Wen-Qi Jiang Tong-Yu Lin Zhong-Jun Xia Qing-Qing Cai 2017Chinese Journal of Cancer2017,36,12:12
