3Improving the outcomes in gastric cancer surgery显示文摘Gastric cancer remains a significant health problem worldwide and surgery is currently the only potentially curative treatment option. Gastric cancer surgery is generally considered to be high risk surgery and fiveyear survival rates are poor,therefore a continuous strive to improve outcomes for these patients is warranted. Fortunately,in the last decades several potential advances have been introduced that intervene at various stages of the treatment process. This review provides an overview of methods implemented in pre-,intra- and postoperative stage of gastric cancer surgery to improve outcome. Better preoperative risk assessment using comorbidity index(e.g.,Charlson comorbidity index),assessment of nutritional status(e.g.,short nutritional assessment questionnaire,nutritional risk screening- 2002) and frailty assessment(Groningen frailty indicator,Edmonton frail scale,Hopkins frailty) was introduced. Also preoperative optimization of patients using prehabilitation has future potential.Implementation of fast-track or enhanced recovery after surgery programs is showing promising results,although future studies have to determine what the exact optimal strategy is.Introduction of laparoscopic surgery has shown improvement of results as well as optimization of lymph node dissection.Hyperthermic intraperitoneal chemotherapy has not shown to be beneficial in peritoneal metastatic disease thus far.Advances in postoperative care include optimal timing of oral diet,which has been shown to reduce hospital stay.In general,hospital volume,i.e.,centralization,and clinical audits might further improve the outcome in gastric cancer surgery.In conclusion,progress has been made in improving the surgical treatment of gastric cancer.However,gastric cancer treatment is high risk surgery and many areas for future research remain.Juul JW Tegels Michiel FG De Maat Karel WE Hulsewé Anton GM Hoofwijk Jan HMB Stoot 2014World Journal of Gastroenterology2014,20,38:16

5Tumor size as a prognostic factor in patients with advanced gastric cancer in the lower third of the stomach显示文摘AIM: To explore the impact of tumor size on outcomes in patients with advanced gastric cancer in the lower third of the stomach. METHODS: We retrospectively analyzed the clinical records of 430 patients with advanced gastric cancer in the lower third of the stomach who underwent distal subtotal gastrectomy and D2 lymphadenectomy in our hospital from January 1998 to June 2004. Receiver-operating characteristic (ROC) curve analysis was used to determine the appropriate cutoff value for tumor size, which was measured as maximum tumor diameter. Based on this cutoff value, patients were divided into two groups: those with large-sized tumors (LSTs) and those with small-sized tumors (SSTs). The correlations between other clinicopathologic factors and tumor size were investigated, and the 5-year overall survival (OS) rate was compared between the two groups. Potential prognostic factors were evaluated by univariate KaplanMeier survival analysis and multivariate Cox's propor-tional hazard model analysis. The 5-year OS rates in the two groups were compared according to pT stage and pN stage. RESULTS: The 5-year OS rate in the 430 patients with advanced gastric cancer in the lower third of the stomach was 53.7%. The mean ± SD tumor size was 4.9 ± 1.9 cm, and the median tumor size was 5.0 cm. ROC analysis indicated that the sensitivity and specificity results for the appropriate tumor size cutoff value of 4.8 cm were 80.0% and 68.2%, respectively (AUC=0.795, 95%CI: 0.751-0.839, P=0.000). Using this cutoff value, 222 patients (51.6%) had LSTs (tumor size ≥ 4.8 cm) and 208 (48.4%) had SSTs (tumor size<4.8 cm). Tumor size was significantly correlated with histological type (P=0.039), Borrmann type (P=0.000), depth of tumor invasion (P=0.000), lymph node metastasis (P=0.000), tumor-nodes metastasis stage (P=0.000), mean number of metastatic lymph nodes (P=0.000) and metastatic lymph node ratio (P=0.000). Patients with LSTs had a significantly lower 5-year OS rate than those with SSTs (37.1% vs 63.3%, P=0.000). Univariate analysis showed that depth of tumor invasion (c 2=69.581, P=0.000), lymph node metastasis (c 2=138.815, P=0.000), tumor size (c 2=78.184, P=0.000) and metastatic lymph node ratio (c 2=139.034, P=0.000) were significantly associated with 5-year OS rate. Multivariate analysis revealed that depth of tumor invasion (P=0.000), lymph node metastasis (P=0.019) and tumor size (P=0.000) were independent prognostic factors. Gastric cancers were divided into 12 subgroups: pT2N0; pT2N1; pT2N2; pT2N3; pT3N0; pT3N1; pT3N2; pT3N3; pT4aN0; pT4aN1; pT4aN2; and pT4aN3. In patients with pT2-3N3 stage tumors and patients with pT4a stage tumors, 5-year OS rates were significantly lower for LSTs than for SSTs (P<0.05 each), but there were no significant differences in the 5-year OS rates in LST and SST patients with pT23N0-2 stage tumors (P > 0.05). CONCLUSION: Using a tumor size cutoff value of 4.8cm, tumor size is a prognostic factor in patients with pN3 stage or pT4a stage advanced gastric cancer located in the lower third of the stomach.Hong-Mei Wang, Chang-Ming Huang, Chao-Hui Zheng, Ping Li, Jian-Wei Xie, Jia-Bin Wang, Jian-Xian Lin, Jun Lu, Department of Gastric Surgery, Affiliated Union Hospital of Fujian Medical University, Fuzhou 350001, Fujian Province, China Author contributions: Wang HM and Huang CM conceived of the study, analyzed the data, and drafted the manuscript Zheng CH, Li P and Xie JW helped revise the manuscript critically for important intellectual content Wang JB, Lin JX and Lu J helped collect data and design the study and all authors read and approved the final manuscript. 2012World Journal of Gastroenterology2012,18,38:15
6Portal vein embolization by fine needle ethanol injection :experimental and clinicalstudies显示文摘AIM To improve the technique of intraportal embolization (PVE) therapy, a new embolic method, was devised and the safety, effectiveness and feasibility were evaluated. METHODS PVE with intraportal ethanol injection via a fine needle was performed in 28 normal dogs, 22 SD rats, and 24 cirrhotic SD rats. After PVE, portography, histological and functional alteration of the liver were evaluated in dogs and rats, and the changes in portal hemodynamics as well as hepatic anatomy were observed in rats. In the clinical study, PVE by ethanol injection was performed in 61 patients with hepatocellular carcinoma under the guidance of portoechography with intraportal injection of CO 2. The effect of PVE was evaluated by ultrasonography and laparotomy. RESULTS The effectiveness and toxicity were dependent on the dose of ethanol. In the dogs, 0 25*!mg/*!kg of ethanol caused incomplete embolization with least liver damage, while 1 0*!mg/*!kg induced complete embolization with a high mortality of 57 1% (4/*!7) due to respiratory arrest. The dose of 0 5*!mg/*!kg resulted in complete embolization with slight toxicity to the liver. In the rats, the survival rate was 100% in normal group but 40 9% in cirrhotic models after ethanol injection by dose of 0 05*!mg/*!100*!g . PVE for cirrhotic rats with 0 03*!mg/*!100*!g of ethanol induced satisfactory embolization with significant hypertrophy in nonembolized lobes, and only slight damage to the hepatic parenchyma, and transient alteration in liver function, portal pressure and portal flow. In the clinical study, 12 cases with reverse portal flow were excluded judged by portoechography. Satisfactory embolization was gained in 90 2% (55/*!61) of the remaining patients determined by ultrasonography and surgery. All cases ran an uneventful postembolization course with no aberrant embolization. CONCLUSION PVE with intraportal ethanol injection of appropriate dosage via a fine needle is safe and effective and has several advantages comparing with transcatheter method. Portoechography is a mandatory approach for the prevention of aberrant embolization.Lu MD Chen JW Xie XY Liang LJ Huang JF 1999World Journal of Gastroenterology1999,5,6:15
7Role of matrix metalloproteinase,tissue inhibitor of metalloproteinase and tumor necrosis factor-α single nucleotide gene polymorphisms in inflammatory bowel disease显示文摘AIM:To study the (functional) relevance of single nucleotide polymorphisms (SNPs) in genes encoding matrix metalloproteinases (MMP)-1,-2,-3,-9,tissue inhibitors of metalloproteinases (TIMP)-1,-2 and tumor necrosis factor (TNF)-α in the etiopathogenesis of inflammatory bowel diseases (IBD),that may enhance susceptibility and/or disease severity. METHODS:Genomic DNA from 134 Crohn's disease (CD),111 ulcerative colitis (UC) patients and 248 control subjects was isolated from resected intestinal tissue or blood. Allelic composition at SNP loci was determined by PCR-RFLP or tetra primer ARMS PCR. RESULTS:The TIMP-1 genotype TT in women and T in men at SNP +372 T/C was found to increase CD susceptibility (39% vs 23.8%,P=0.018 and 67.9% vs 51.6%,P=0.055,respectively),while women with this genotype were less prone to development of fistulae during follow-up (41.4% vs 68.3%,P=0.025). Male IBD or CD patients carrying the TIMP-1 +372 T-allele expressed lower levels of TIMP-1 in surgically resected macroscopically inflamed tissue (0.065 < P < 0.01). The 5T5T genotype at MMP-3 SNP -1613 5T/6T increased the chance of stenotic complications in CD during follow-up (91.2% vs 71.8%,P = 0.022) but seemed to protect against colonic involvement of this disease at first endoscopic/radiologic examination (35.3% vs 59.5%,P=0.017). CONCLUSION:Allelic composition at the examinedSNPs in genes coding for TIMP-1 and MMP-3 affect CD susceptibility and/or phenotype,i.e.,fistulizing disease,stricture pathogenesis and first disease localisation. These findings reinforce the important role of these proteins in IBD.Martin JW Meijer Marij AC Mieremet-Ooms Ruud A van Hogezand Cornelis BHW Lamers Daniel W Hommes Hein W Verspaget 2007World Journal of Gastroenterology2007,13,21:15
8Expression of perforin and granzyme B mRNA in judgement of immunosuppressive effect in rat liver transplantation显示文摘AIM To explore the expression of perform andgranzyme B genes mRNA to judge the effect ofimmunosuppression in acute rejection of livertransplantation.METHODS The expression of perform andgranzyme B genes mRNA was examined byreverse transcriptase-polymerase chain reaction(RT--PCR) in hamster to rat liver grafts under theimmunosuppression of cyclosporine or/andsplenectomy. Histological findings were studiedcomparatively.RESULTS Cyclosporine could obviouslydecrease the cellular infiltration, and completelyrepress the expression of mRNA for perform andgranzyme B, but could not change severehepatocyte necrosis and hemorrhage.SPlenectomy could significantly lightenhepatocyte necrosis, and completely eliminatehemorrhage, but not atfect the cellularinfiltration and the expression of perform andgranzyme B genes mRNA. Cyclosporine orsplenectomy alone could not prolong theSurvival time, however, their combination couldcompletely repress the rejection of liver grafts.The survival time of animals were significantlyprolonged (37.1 days ). The architecture ofhepatic lobules was preserved. There was slightcellular infiltration in the portal tracts and noexpression of perform and granzyme B genesmRNA could be seen in three weeks aftertransplantation.CONCLUSION Perform and granzyme B genesare valuable in judging the effect ofimmunosuppression in liver transplantation.Zhang SG Wu MC Tan JW Chen H Yang JM Qian QJ 1999World Journal of Gastroenterology1999,5,3:15
9急性脊髓损伤患者治疗的临床操作指南:关于MRI基线在临床治疗决策与结果预测中作用的几点建议(英文)显示文摘The objective of this guideline is to outline the role of magnetic resonance imaging(MRI) in clinical decision making and outcome prediction in patients with traumatic spinal cord injury(SCI).Methods A systematic review of the literature was conducted to address key questions related to the use of MRI in patients with traumatic SCI.This review focused on longitudinal studies that controlled for baseline neurologic status.A multidisciplinary Guideline Development Group(GDG) used this information,their clinical expertise,and patient input to develop recommendations on the use of MRI for SCI patients.Based on GRADE(Grading of Recommendation,Assessment,Development and Evaluation),a strong recommendation is worded as ' we recommend,' whereas a weaker recommendation is indicated by 'we suggest.' Results Based on the limited available evidence and the clinical expertise of the GDG,our recommendations were:(1) 'We suggest that MRI be performed in adult patients with acute SCI prior to surgical intervention,when feasible,to facilitate improved clinical decision-making'(quality of evidence,very low) and(2) 'We suggest that MRI should be performed in adult patients in the acute period following SCI,before or after surgical intervention,to improve prediction of neurologic outcome '(quality of evidence,low).Conclusions These guidelines should be implemented into clinical practice to improve outcomes and prognostication for patients with SCI.Fehlings MG Martin AR Tetreault LA Aarabi B Anderson P Arnold PM Brodke D Burns AS Chiba K Dettori JR Furlan JC Hawryluk G Holly LT Howley S Jeji T Kalsi-Ryan S Kotter M Kurpad S Kwon BK Marino RJ Massicotte E Merli G Middleton JW Nakashima H Nagoshi N Palmieri K Singh A Skelly AC Tsai EC Vaccaro A Wilson JR Yee A Harrop JS 2017中华神经外科疾病研究杂志2017,16,6:8

11m TOR signaling in liver regeneration: Rapamycin combined with growth factor treatment显示文摘AIM: To investigate the effects of mammalian target of rapamycin(mT OR) inhibition on liver regeneration and autophagy in a surgical resection model.METHODS: C57BL/6 mice were subjected to a 70% partial hepatectomy(PH) and treated intraperitoneally every 24 h with a combination of the m TOR inhibitor rapamycin(2.5 mg/kg per day) and the steroid dexamethasone(2.0 mg/kg per day) in phosphate bufferedsaline(PBS) or with PBS alone as vehicle control. In the immunosuppressant group, part of the group was treated subcutaneously 4 h prior to and 24 h after PH with a combination of human recombinant interleukin 6(IL-6; 500 μg/kg per day) and hepatocyte growth factor(HGF; 100 μg/kg per day) in PBS. Animals were sacrificed 2, 3 or 5 d after PH and liver tissue and blood were collected for further analysis. Immunohistochemical staining for 5-Bromo-2'-deoxyuridine(Brd U) was used to quantify hepatocyte proliferation. Western blotting was used to detect hepatic microtubule-associated protein 1 light chain 3(LC3)-Ⅱ protein expression as a marker for autophagy. Hepatic gene expression levels of proliferation-, inflammation- and angiogenesisrelated genes were examined by real-time reverse transcription-polymerase chain reaction and serum bilirubin and transaminase levels were analyzed at the clinical chemical core facility of the Erasmus MC-University Medical Center.RESULTS: m TOR inhibition significantly suppressed regeneration, shown by decreased hepatocyte proliferation(2% vs 12% Brd U positive hepatocyte nuclei at day 2, P < 0.01; 0.8% vs 1.4% at day 5, P = 0.02) and liver weight reconstitution(63% vs 76% of initial total liver weight at day 3, P = 0.04), and furthermore increased serum transaminase levels(aspartate aminotransferase 641 U/L vs 185 U/L at day 2, P = 0.02). Expression of the autophagy marker LC3-Ⅱ, which was reduced during normal liver regeneration, increased after mT OR inhibition(46% increase at day 2, P = 0.04). Hepatic gene expression showed an increased inflammation-related response [tumor necrosis factor(TNF)-α 3.2-fold upregulation at day 2, P = 0.03; IL-1Ra 6.0-fold upregulation at day 2 and 42.3-fold upregulation at day 5, P < 0.01] and a reduced expression of cell cycle progression and angiogenesis-related factors(HGF 40% reduction at day 2; vascular endothelial growth factor receptor 2 50% reduction at days 2 and 5; angiopoietin 1 60% reduction at day 2, all P ≤ 0.01). Treatmentwith the regeneration stimulating cytokine IL-6 and growth factor HGF could overcome the inhibitory effect on liver weight(75% of initial total liver weight at day 3, P = 0.02 vs immunosuppression alone and P = 0.90 vs controls) and partially reversed gene expression changes caused by rapamycin(TNF-α and IL-1Ra levels at day 2 were restored to control levels). However, no significant changes in hepatocyte proliferation, serum injury markers or autophagy were found.CONCLUSION: mT OR inhibition severely impairs liver regeneration and increases autophagy after PH. These effects are partly reversed by stimulation of the IL-6 and HGF pathways.Suomi MG Fouraschen Petra E de Ruiter Jaap Kwekkeboom Ron WF de Bruin Geert Kazemier Herold J Metselaar Hugo W Tilanus Luc JW van der Laan Jeroen de Jonge 2013World Journal of Transplantation2013,3,3:6

13Tumour suppressor HLJ1: A potential diagnostic, preventive and therapeutic target in non-small cell lung cancer显示文摘Lung cancer is the leading cause of cancer-related mortality throughout the world. Non-small cell lung cancer(NSCLC) accounts for 85% of all diagnosed lung cancers. Despite considerable progress in the diagnosis and treatment of the disease, the overall 5-year survival rate of NSCLC patients remains lower than 15%. The most common causes of death in lung cancer patients are treatment failure and metastasis. Therefore, developing novel strategies that target both tumour growth and metastasis is an important and urgent mission for the next generation of anticancer therapy research. Heat shock proteins(HSPs), which are involved in the fundamental defence mechanism for maintaining cellular viability, are markedly activated during environmen-tal or pathogenic stress. HSPs facilitate rapid cell division, metastasis, and the evasion of apoptosis in cancer development. These proteins are essential players in the development of cancer and are prime therapeutic targets. In this review, we focus on the current understanding of the molecular mechanisms responsible for HLJ1's role in lung cancer carcinogenesis and progression. HLJ1, a member of the human HSP 40 family, has been characterised as a tumour suppressor. Research studies have also reported that HLJ1 shows promising dual anticancer effects, inhibiting both tumour growth and metastasis in NSCLC. The accumulated evidence suggests that HLJ1 is a potential biomarker and treatment target for NSCLC.Meng-Feng Tsai Chi-Chung Wang Jeremy JW Chen 2014World Journal of Clinical Oncology2014,5,5:6

15New therapeutic opportunities for Hepatitis C based on small RNA显示文摘Hepatitis C virus (HCV) infection is one of the major causes of chronic liver disease, including cirrhosis and liver cancer and is therefore, the most common indication for liver transplantation. Conventional antiviral drugs such as pegylated interferon-alpha, taken in combination with ribavirin, represent a milestone in the therapy of this disease. However, due to different viral and host factors, clinical success can be achieved only in approximately half of patients, making urgent the requirement of exploiting alternative approaches for HCV therapy. Fortunately, recent advances in the understanding of HCV viral replication and host cell interactions have opened new possibilities for therapeutic intervention. The most recent technologies, such as small interference RNA mediated gene-silencing, anti-sense oligonucleotides (ASO), or viral vector based gene delivery systems, have paved the way to develop novel therapeutic modalities for HCV. In this review, we outline the application of these technologies in the context of HCV therapy. In particular, we will focus on the newly defined role of cellular microRNA (miR-122) in viral replication and discuss its potential for HCV molecular therapy.Qiu-wei Pan Scot D Henry Bob J Scholte Hugo W Tilanus Harry LA Janssen Luc JW van der Laan 2007World Journal of Gastroenterology2007,13,33:4
16血栓素(thromboxane)合成酶抑制剂——Dazmegrel(UK38,485)对烧伤皮肤血流灌注的影响显示文摘近十年来,血栓素(thromboxane)被认为在烧伤后真皮进行性缺血过程中起重要作用,有报导前列腺素、血栓素抑制剂可改善局部血循环,从而促进深Ⅱ度烧伤刨而愈合。本实验以啄鼠深Ⅱ度烧伤模型,肌注血栓素合成酶抑制剂Dazmegrel(UK38,485或uk)3.4mg/kg/天(UK3.4mg)、10mE/kg/天(UK10mg)、或30mg/kg/天(UK30mg),使用印度墨汁灌注及UK-133(氙-133)清除试验,未发现Dazfilegrel能改善烧伤局部血流。这与有的实验结论不同,肌注Dazmegrel 3.4rag/kg/天的促进烧伤创面愈合作用,不是由于该药改善局部血流量所致。此外,Xe-133清除试验示伤后7小时深Ⅱ度烧伤皮肤血流量有一明显下降过程,伤后24小时则有一明显增加过程,如何认识及应用这一'先低后高。现象,对促进深Ⅱ度烧伤创面愈合显然是有意义的。汪仕良 黎鳌 Alexander JW Silberstein EB Robb E Lukes S Trocki O Ogle DK 邹万忠 1989中华整形烧伤外科杂志1989,5,3:3
