1胃癌:诊断和治疗方案的选择显示文摘胃癌是消化系统最常见的恶性肿瘤之一,是世界上第四高发肿瘤,也是我国目前第二高发肿瘤。据统计,在2013年全球胃癌新增的952000例患者中,中国占47%,其发病率远高于欧美等国家。广泛的癌细胞转移使我国每年有352300人死于胃癌,死亡率位居第三。由于早期症状不典型且胃镜常规检查未普及,我国60%~80%的胃癌患者就诊时已到晚期。加上现有治疗手段获益有限,预后差,晚期胃癌患者5年生存率不超过20%。因此,如何及早发现胃癌,进而预防和治疗胃癌是广大医师关注的热点问题。为使广大医师对胃癌有深入了解,本期“专题研究”栏目对胃癌转移的机制进行了分析,发现锌指蛋白139(ZNF139)可调控胃癌肿瘤细胞凋亡、随肿瘤转移而表达增强,成为导致肿瘤进展的可能因素之一。同时,为使广大医师及时了解胃癌治疗的新动向,本期又从胃癌根治术中纳米炭淋巴示踪剂的作用以及胃癌微创治疗进展方面进行了探讨与论述,为临床今后胃癌治疗的研究提供了理论依据和方向。John C.

4Platelet thromboxane(11-dehydro-Thromboxane B_2) and aspirin response in patients with diabetes and coronary artery disease显示文摘Aspirin(ASA) irreversibly inhibits platelet cyclooxygenase-1(COX-1) leading to decreased thromboxane-mediated platelet activation. The effect of ASA ingestion on thromboxane generation was evaluated in patients with diabetes(DM) and cardiovascular disease. Thromboxane inhibition was assessed by measuring the urinary excretion of 11-dehydro-thromboxane B2(11dhTxB2), a stable metabolite of thromboxane A2. The mean baseline urinary 11dhTxB2 of DM was 69.6% higher than healthy controls(P = 0.024): female subjects(DM and controls) had 50.9% higher baseline 11dhTxB2 than males(P = 0.0004), while age or disease duration had no influence. Daily ASA ingestion inhibited urinary 11dhTxB2 in both DM(71.7%) and controls(75.1%, P < 0.0001). Using a pre-established cut-off of 1500 pg/mg of urinary 11dhTxB2, there were twice as many ASA poor responders(ASA 'resistant') in DM than in controls(14.8% and 8.4%, respectively). The rate of ASA poor responders in two populations of acute coronary syndrome(ACS) patients was 28.6 and 28.7%, in spite of a significant(81.6%) inhibition of urinary 11dhTxB2(P < 0.0001). Both baseline 11dhTxB2 levels and rate of poor ASA responders were significantly higher in DM and ACS compared to controls. Underlying systemic oxidative inflammation may maintain platelet function in atherosclerotic cardiovascular disease irrespective of COX-1 pathway inhibition and/or increase systemic generation of thromboxane from non-platelet sources.Luis R Lopez Kirk E Guyer Ignacio Garcia De La Torre Kelly R Pitts Eiji Matsuura Paul RJ Ames 2014World Journal of Diabetes2014,5,2:13
5以区域医疗中心为主导的护联体的构建与实施显示文摘目的带领社区医护人员为居家患者提供有偿优质护理服务。方法构建以基层医疗为中心,以区域医疗中心为主导的护联体平台;实行患者线上下单,区域医疗中心护士与社区护士联合上门居家护理服务的方式。实施1年后评价效果。结果护联体运行以来,107名医疗中心护士带领社区护士共提供上门更换胃管、PICC维护、更换尿管、伤口造口护理、压疮护理等14个项目的护理服务;其中更换胃管(73例次)堵管率、PICC维护(97例次)静脉炎发生率显著低于返院维护组(护联体平台运行前,返院更换胃管53例次、PICC维护80例次)(均P<0.05);患者满意度评分显著高于返院组(P<0.01);两种护理模式均未发生护理不良事件与纠纷。结论基于护联体模式的“互联网+护理服务”,可一定程度上满足居家患者的护理需求,护患双方均有较好的安全保障。谭江红 田艳珍 王浪 孙亭亭 黄红斌 包正军 Rodrigo Lopez 2021护理学杂志2021,36,12:13
6Disassembly of the fruit cell wall by the ripening-associated polygalacturonase and expansin influences tomato cracking显示文摘Fruit cracking is an important problem in horticultural crop production.Polygalacturonase(SlPG)and expansin(SlEXP1)proteins cooperatively disassemble the polysaccharide network of tomato fruit cell walls during ripening and thereby,enable softening.A Golden 2-like(GLK2)transcription factor,SlGLK2 regulates unripe fruit chloroplast development and results in elevated soluble solids and carotenoids in ripe fruit.To determine whether SlPG,SlEXP1,or SlGLK2 influence the rate of tomato fruit cracking,the incidence of fruit epidermal cracking was compared between wild-type,Ailsa Craig(WT)and fruit with suppressed SlPG and SlEXP1 expression(pg/exp)or expressing a truncated nonfunctional Slglk2(glk2).Treating plants with exogenous ABA increases xylemic flow into fruit.Our results showed that ABA treatment of tomato plants greatly increased cracking of fruit from WT and glk2 mutant,but not from pg/exp genotypes.The pg/exp fruit were firmer,had higher total soluble solids,denser cell walls and thicker cuticles than fruit of the other genotypes.Fruit from the ABA treated pg/exp fruit had cell walls with less water-soluble and more ionically and covalently-bound pectins than fruit from the other lines,demonstrating that ripening-related disassembly of the fruit cell wall,but not elimination of SlGLK2,influences cracking.Cracking incidence was significantly correlated with cell wall and wax thickness,and the content of cell wall protopectin and cellulose,but not with Ca^(2+)content.Fangling Jiang Alfonso Lopez Shinjae Jeon Sergio Tonetto de Freitas Qinghui Yu Zhen Wu John M.Labavitch Shengke Tian Ann L.T.Powell Elizabeth Mitcham 2019Horticulture Research2019,6,1:13

9源于近端股骨间充质干细胞免疫抑制作用的研究显示文摘目的探讨源于成人近端股骨的间充质干细胞(MSC)是否具有免疫抑制功能,为临床移植物抗宿主病的防治寻找理想的细胞储备库。方法从全髋关节置换术患者的近端股骨中分离并培养MSC,将不同数量的细胞直接或以Transwell法加入混合淋巴细胞反应(MLR)中,检测MSC对外周血淋巴细胞(PBL)增殖水平的影响。以ELISA法及抗体中和法探讨细胞因子TGFβ1在MSC免疫调节中的作用。结果3×103、1×104、3×104、1×105个源于近端股骨的MSC对PBL增殖的抑制率分别为62%±18%、38%±4%、31%±16%、28%±12%,与采自髂骨骨髓穿刺物MSC的抑制作用相比差异无统计学意义(均P>0.05),后者对PBL的增殖抑制率为58%±12%、37%±8%、28%±6%、27%±6%;以0.2μm的微孔膜对MSC与MLR进行分隔,3×104及1×104个MSC对PBL的增殖抑制率为36%±8%和53%±12%;在ELISA实验中,MSC单独培养,MSC与MLR直接接触,或经Transwell共培养的这3种上清中转化生长因子(TGF)β1的表达水平差异无统计学意义,加入浓度递增的TGFβ1抗体不能逆转MSC对PBL增殖的抑制作用。结论源于近端股骨的MSC具有一定的免疫抑制功能,除TGFβ1外其他可溶性因子可能介导这一作用。张翼鷟 Loic Fouillard Alain Chapel Morad Bensidhoum Christelle Mazurier Aish Nasef Sandrine Bouchet Manuel Lopez Dominique Thierry Norbert Cclaucle Gorin 达万明 2005中华医学杂志2005,85,39:11
10Borderline resectable pancreatic cancer: Definitions and management显示文摘Pancreatic cancer is the fourth leading cause of cancer death in the United States. While surgical resection remains the only curative option, more than 80% of patients present with unresectable disease. Unfortunately, even among those who undergo resection, the reported median survival is 15-23 mo, with a 5-year survival of approximately 20%. Disappointingly, over the past several decades, despite improvements in diagnostic imaging, surgical technique and chemotherapeutic options, only modest improvements in survival have been realized. Nevertheless, it remains clear that surgical resection is a prerequisite for achieving longterm survival and cure. There is now emerging consensus that a subgroup of patients, previously considered poor candidates for resection because of the relationship of their primary tumor to surrounding vasculature, may benefit from resection, particularly when preceded by neoadjuvant therapy. This stage of disease, termed borderline resectable pancreatic cancer, has become of increasing interest and is now the focus of a multiinstitutional clinical trial. Here we outline the history, progress, current treatment recommendations, and future directions for research in borderline resectable pancreatic cancer.Nicole E Lopez Cristina Prendergast Andrew M Lowy 2014World Journal of Gastroenterology2014,20,31:11
11Identification of colorectal cancer metastasis markers by an angiogenesis-related cytokine-antibody array显示文摘AIM:To investigate the angiogenesis-related protein expression profile characterizing metastatic colorectal cancer (mCRC) with the aim of identifying prognostic markers.METHODS:The expression of 44 angiogenesissecreted factors was measured by a novel cytokine antibody array methodology.The study evaluated vascular endothelial growth factor (VEGF) and its soluble vascular endothelial growth factor receptor (sVEGFR)-1 protein levels by enzyme immunoassay (EIA) in a panel of 16 CRC cell lines.mRNA VEGF and VEGF-A isoforms were quantified by quantitative reverse-transcription polymerase chain reaction (Q-RT-PCR) and vascular endothelial growth factor receptor (VEGFR)-2 expression was analyzed by flow cytometry.RESULTS:Metastasis-derived CRC cell lines expressed a distinctive molecular profile as compared with those isolated from a primary tumor site.Metastatic CRC cell lines were characterized by higher expression of angiogenin-2 (Ang-2),macrophage chemoattractant proteins-3/4 (MCP-3/4),matrix metalloproteinase-1 (MMP-1),and the chemokines interferon γ inducible T cell α chemoattractant protein (I-TAC),monocyte chemoattractant protein I-309,and interleukins interleukin (IL)-2 and IL-1α,as compared to primary tumor cell lines.In contrast,primary CRC cell lines expressed higher levels of interferon γ (IFN-γ),insulin-like growth factor-1 (IGF-1),IL-6,leptin,epidermal growth factor (EGF),placental growth factor (PlGF),thrombopoietin,transforming growth factor β1 (TGF-β1) and VEGF-D,as compared with the metastatic cell lines.VEGF expression does not significantly differ according to the CRC cellular origin in normoxia.Severe hypoxia induced VEGF expression up-regulation but contrary to expectations,metastatic CRC cell lines did not respond as much as primary cell lines to the hypoxic stimulus.In CRC primary-derived cell lines,we observed a twofold increase in VEGF expression between normoxia and hypoxia as compared to metastatic cell lines.CRC cell lines express a similar pattern of VEGF isoforms (VEGF 121,VEGF 165 and VEGF 189) despite variability in VEGF expression,where the major transcript was VEGF 121.No relevant expression of VEGFR-2 was found in CRC cell lines,as compared to that of human umbilical vein endothelial cells and sVEGFR-1 expression did not depend on the CRC cellular origin.CONCLUSION:A distinct angiogenesis-related expression pattern characterizes metastatic CRC cell lines.Factors other than VEGF appear as prognostic markers and intervention targets in the metastatic CRC setting.Ana Abajo Nerea Bitarte Ruth Zarate Valentina Boni Ines Lopez Marisol Gonzalez-Huarriz Javier Rodriguez Eva Bandres Jesus Garcia-Foncillas 2012World Journal of Gastroenterology2012,18,7:8
12Over-expression of fibroblast growth factor receptor 3 in human hepatocellular carcinoma显示文摘AIM: To describe the significant over-expression of fibroblast growth factor receptor 3 (FGFR3), which is a signal transduction and cell proliferation related gene in hepatocellular carcinoma (HCC).METHODS: Following DNA microarray, Northern blot and quantitative real-time PCR were employed to confirm FGFR3 expression difference in HCC tissues and surrounding non-neoplastic liver tissue. FGFR3 expression levels were further determined by immunohistochemical study in 43 cases of HCC.RESULTS: Northern blot results showed the significant over-expression of FGFR3 in HCC tissues, which was consistent with that from DNA microarray. Quantitative real-time PCR demonstrated that the mean ratio of FGFR3 mRNA to glyceraldehyde-3-phosphate dehydrogenase (GADPH) mRNA in HCC tissue was 0.250, whereas the ratio in non-neoplastic liver tissue was 0.014. Statistical analyses of 43 cases of HCC revealed that HCC scored higher than the matched non-neoplastic liver tissues.Examination of clinicopathological features revealed a strong correlation of over-expression of FGFR3 with poor tumor differentiation and high nuclear grade.CONCLUSION: Over-expression of FGFR3 may play an important role in liver carcinogenesis. FGFR3 may be an ideal candidate as a molecular marker in the diagnosis of HCC and a potential therapeutic target.Wei-Hua Qiu Bing-Sen Zhou Peiguo G.

15Efficacy of peroral endoscopic myotomy vs other achalasia treatments in improving esophageal function显示文摘AIM: To assess and compare the esophageal function after peroral endoscopic myotomy(POEM) vs other conventional treatments in achalasia.METHODS: Chart review of all achalasia patients who underwent POEM, laparoscopic Heller myotomy(LHM) or pneumatic dilation(PD) at our institution between January 2012 and March 2015 was performed. Patient demographics, type of achalasia, prior treatments, pre- and post-treatment timed barium swallow(TBE) and high-resolution esophageal manometry(HREM) findings were compared between the three treatment groups. Patients who had both pre- and 2 mo posttreatment TBE or HREM were included in the final analysis. TBE parameters compared were barium column height, width and volume of barium remaining at 1 and 5 min. HREM parameters compared were basal lower esophageal sphincter(LES) pressures and LES-integrated relaxation pressures(IRP). Data are presented as mean ± SD, median [25th, 75 th percentiles] or frequency(percent). Analysis of variance, KruskalWallis test, Pearsons χ~2 test and Fishers Exact tests were used for analysis.RESULTS: A total of 200 achalasia patients were included of which 36 underwent POEM, 22 underwent PD and 142 underwent LHM. POEM patients were older(55.4 ± 16.8 years vs 46.5 ± 15.7 years, P = 0.013) and had higher BMI than LHM(29.1 ± 5.9 kg/m^2 vs 26 ± 5.1 kg/m^2, P = 0.012). More number of patients in POEM and PD groups had undergone prior treatments compared to LHM group(72.2% vs 68.2% vs 44.3% respectively, P = 0.003). At 2 mo post-treatment, all TBE parameters including barium column height, width and volume remaining at 1 and 5 min improved significantly in all three treatment groups(P = 0.01 to P < 0.001) except the column height at 1 min in PD group(P = 0.11). At 2 mo post-treatment, there was significant improvement in basal LES pressure and LES-IRP in both LHM(40.5 mm Hg vs 14.5 mm Hg and 24 mm Hg vs 7.1 mm Hg respectively, P < 0.001) and POEM groups(38.7 mm Hg vs 11.4 mm Hg and 23.6 mm Hg vs 6.6 mm Hg respectively, P < 0.001). However, when the efficacy of three treatments were compared to each other in terms of improvement in TBE or HREM parameters at 2 mo, there was no significant difference(P > 0.05).CONCLUSION: POEM, PD and LHM were all effective in improving esophageal function in achalasia at shortterm. There was no difference in efficacy between the three treatments.Madhusudhan R Sanaka Umar Hayat Prashanthi N Thota Ramprasad Jegadeesan Monica Ray Scott L Gabbard Neha Wadhwa Rocio Lopez Mark E Baker Sudish Murthy Siva Raja 2016World Journal of Gastroenterology2016,22,20:7
16非诺贝特治疗与2型糖尿病患者长期心血管病风险的关系显示文摘2型糖尿病患者心血管病风险高,部分原因在于高三酰甘油和低高密度脂蛋白胆固醇血症。而在他汀类药物治疗基础上,加强降低三酰甘油治疗,能否降低这种风险尚不清楚。该研究的目的是在使用他汀类药物治疗的2型糖尿病患者中,确定非诺贝特能否降低心血管病风险。刘莉 叶鹏 Elam MB Ginsberg HN Lovato LC Corson M Largay J Leiter LA Lopez C O'Connor PJ Sweeney ME Weiss D Friedewald WT Buse JB Gerstein HC Probstfield J Grimm R Ismail-Beigi F Goff DC Jr Fleg JL Rosenberg Y Byington RP ACCORDION study investigators 2017中华高血压杂志2017,25,6:7

19Role of aldehyde dehydrogenase 2 in ischemia reperfusion injury:An update显示文摘Aldehyde dehydrogenase 2(ALDH2) is best known for its critical detoxifying role in liver alcohol metabolism. However, ALDH2 dysfunction is also involved in a wide range of human pathophysiological situations and is associated with complications such as cardiovascular diseases, diabetes mellitus, neurodegenerative diseases and aging. A growing body of research has shown that ALDH2 provides important protection against oxidative stress and the subsequent loading of toxic aldehydes such as 4-hydroxy-2-nonenal and adducts that occur in human diseases, including ischemia reperfusion injury(IRI). There is increasing evidence of its role in IRI pathophysiology in organs such as heart, brain, small intestine and kidney; however, surprisingly few studies have been carried out in the liver, where ALDH2 is found in abundance. This study reviews the role of ALDH2 in modulating the pathways involved in the pathophysiology of IRI associated with oxidative stress, autophagy and apoptosis. Special emphasis is placed on the role of ALDH2 in different organs, on therapeutic 'preconditioning' strategies, and on the use of ALDH2 agonists such as Alda-1, which may become a useful therapeutic tool for preventing the deleterious effects of IRI in organ transplantation.Arnau Panisello-Roselló Alexandre Lopez Emma Folch-Puy Teresa Carbonell Anabela Rolo Carlos Palmeira René Adam Marc Net Joan Roselló-Catafau 2018World Journal of Gastroenterology2018,24,27:6
