| 1 | Endoclips vs large or small-volume epinephrine in peptic ulcer recurrent bleeding显示文摘AIM:To compare the recurrent bleeding after endoscopic injection of different epinephrine volumes with hemoclips in patients with bleeding peptic ulcer.METHODS:Between January 2005 and December 2009,150 patients with gastric or duodenal bleeding ulcer with major stigmata of hemorrhage and nonbleeding visible vessel in an ulcer bed(Forrest Ⅱa) were included in the study.Patients were randomized to receive a small-volume epinephrine group(15 to 25 mL injection group;Group 1,n = 50),a large-volume epinephrine group(30 to 40 mL injection group;Group 2,n = 50) and a hemoclip group(Group 3,n = 50).The rate of recurrent bleeding,as the primary outcome,was compared between the groups of patients included in the study.Secondary outcomes compared between the groups were primary hemostasis rate,permanent hemostasis,need for emergency surgery,30 d mortality,bleeding-related deaths,length of hospital stay and transfusion requirements.RESULTS:Initial hemostasis was obtained in all patients.The rate of early recurrent bleeding was 30%(15/50) in the small-volume epinephrine group(Group 1) and 16%(8/50) in the large-volume epinephrine group(Group 2)(P = 0.09).The rate of recurrent bleeding was 4%(2/50) in the hemoclip group(Group 3);the difference was statistically significant with regard to patients treated with either small-volume or large-volume epinephrine solution(P = 0.0005 and P = 0.045,respectively).Duration of hospital stay was significantly shorter among patients treated with hemoclips than among patients treated with epinephrine whereas there were no differences in transfusion requirement or even 30 d mortality between the groups.CONCLUSION:Endoclip is superior to both small and large volume injection of epinephrine in the prevention of recurrent bleeding in patients with peptic ulcer. | Neven Ljubicic Ivan Budimir Alen Biscanin Marko Nikolic Vladimir Supanc Davor Hrabar Tajana Pavic | 2012 | World Journal of Gastroenterology2012，18，18： | 11 |
| 2 | Mitotic crossover- an evolutionary rudiment which promotes carcinogenesis of colorectal carcinoma显示文摘Mitotic crossover is a natural mechanism that is a main source of the genetic variability of primitive organisms.In complex organisms such as mammals,it represents an evolutionary rudiment which persisted as one of the numerous DNA repair mechanisms,and results in the production of homozygous allele combinations in all heterozygous genes located on the chromosome arm distal to the crossover.This event is familiar as loss of heterozygosity,which is one of the key mechanisms responsible for the development and progression of almost all cancers.We propose the hypothesis in which mitotic crossover is a principal source of the increased loss of heterozygosity that leads to the initiation and progression of colorectal carcinoma.The hypothesis could be tested by in vitro inhibition of Rad51 protein,orthotopic grafting of human colon cancer tissue into the gut of mice,and treatment with potential inhibitors.After these procedures,the frequency of mitotic crossover would be estimated.The development of selective inhibitors of mitotic crossover could stop further carcinogenesis of colorectal carcinoma,as well as many other neoplastic events.Loss of heterozygosity is an event responsible for carcinogenesis,its reduction by selective inhibitors of mitotic crossover could have a positive effect on cancer chemoprevention,as well as on growth reduction and a cessation in the progression of earlier developed tumors. | Branislav Rovcanin Ivan Ivanovski Olivera Djuric Dimitrije Nikolic Jelena Petrovic Petar Ivanovski | 2014 | World Journal of Gastroenterology2014，20，35： | 2 |
| 3 | Expression of cytokeratins in Helicobacter pylori-associated chronic gastritis of adult patients infected with cagA+strains:An immunohistochemical study显示文摘瞄准:为了与长期的胃炎在成年病人的胃的上皮调查不同 cytokeratins (CK ) 的表示,与 Helicobacter pylori (H pylori ) 感染了 cagA+ 紧张。方法:CK 7 的表示, 8, 18, 19 和 20 在 84 个病人的窦的胃的活体检视组织化学地是学习免疫。所有 CK 是在 cagA+H pylori 胃炎(57 个案例) 染色的免疫, non-H pylori 胃炎(17 个案例) 和正常胃粘膜(10 个案例) 。结果:在 cagA+ H pylori 胃炎, CK8 从表面上皮可比较地被表示到正常的窦粘膜到深腺。CK18 和 CK 19 的分发是未改变的,即表示的 transmucosal,而是紧张在与正常相比的小凹的区域是不同的胃粘膜。Cytokeratin 18 免疫反应在与 H pylori 否定的胃炎和控制相比的 H pylori 积极的胃炎的小凹的上皮是显著地更高的。相反,在 CK19 免疫反应的减少发生在 H pylori 积极的胃炎的小凹的上皮。在没有 H pylori 感染的正常、煽动的窦粘膜, CK20 在表面上皮和上面的小凹的区域强烈 / 中等并且同类地被表示,但是在 H, pylori 导致了胃炎在小凹的区域的表示的重要减少被注意。通常,在正常窦的粘膜和 H pylori 否定的胃炎,, CK7 的表示没被观察在关于半 cagA+ , H 感染 pylori 的病人,节制颈的焦点的 CK7 免疫反应,卷的腺区域被登记,特别在区域与更严重煽动性渗入。结论:在 CK 7 的表示的改变, 18, 19 和 20 在感染 cagA+ 紧张的成年病人和 CK8 的正常表示发生在 H 联系 pylori 的长期的胃炎的窦粘膜。在不同 cytokeratins 表示力量的改变贡献在 H 感染 pylori 的胃粘膜观察的上皮的紧密的连接变弱。 | Vera Todorovic Neda Drndarevic Olivera Mitrovic Institutefor MedicalResearch Aleksandra Sokic-Milutinovic Tomica Milosavljevic Marjan Micev Ivan Nikolic Thomas Wex Peter Malfertheiner | 2006 | World Journal of Gastroenterology2006，12，12： | 2 |

| 8 | Immunotherapy in the treatment of lymphoma显示文摘Relapsed or refractory non-Hodgkin’s lymphomas,especially diffuse large B-cell lymphoma as well as relapsed or refractory Hodgkin lymphomas are hard-to-treat diseases.Patients who do not respond to initial therapy or experience relapse are treated with salvage regimens,and if eligible for aggressive therapy,treatment is continued with high-dose chemotherapy and autologous stem cell transplantation.Current therapy options can cure substantial numbers of patients,however for some it is still an uncurable disease.Numerous new drugs and cell therapies are being investigated for the treatment of relapsed or refractory lymphomas.Different types of immunotherapy options have shown promising results,and some have already become the standard of care.Here,we review immunotherapy options for the treatment of lymphoma and discuss the results,positions,practical aspects,and future directions of different drugs and cellular therapies for the treatment of this disease. | Lazar S Popovic Gorana Matovina-Brko Maja Popovic Milica Popovic Ana Cvetanovic Ivan Nikolic Biljana Kukic Dragana Petrovic | 2021 | World Journal of Stem Cells2021，13，6： | 0 |
| 9 | Effect of special types of bread with select herbal components on postprandial glucose levels in diabetic patients显示文摘BACKGROUND Nutrition recommendations in patients with type 2 diabetes mellitus(T2DM)are to consume rye or integral bread instead of white bread.A positive effect on glucoregulation has been achieved by enriching food with various biologically active substances of herbal origin,so we formulated an herbal mixture that can be used as a supplement for a special type of bread(STB)to achieve better effects on postprandial glucose and insulin levels in patients with T2DM.AIM To compare organoleptic characteristics and effects of two types of bread on postprandial glucose and insulin levels in T2DM patients.METHODS This trial included 97 patients with T2DM.A parallel group of 16 healthy subjects was also investigated.All participants were given 50 g of rye bread and the same amount of a STB with an herbal mixture on 2 consecutive days.Postprandial blood glucose and insulin levels were compared at the 30^(th),60^(th),90^(th) and 120th min.A questionnaire was used for subjective estimation of the organoleptic and satiety features of the two types of bread.RESULTS Compared to patients who consumed rye bread,significantly lower postprandial blood glucose and insulin concentrations were found in T2DM patients who consumed STB.No relevant differences were found among the healthy subjects.Subjectively estimated organoleptic and satiety characteristics are better for STB than for rye bread.CONCLUSION STB have better effects than rye bread on postprandial glucoregulation in T2DM patients.Subjectively estimated organoleptic and satiety characteristics are better for STB than for rye bread.Therefore,STB can be recommended for nutrition in T2DM patients. | Drasko M Gostiljac Srdjan S Popovic Vesna Dimitrijevic-Sreckovic Sasa M Ilic Jelena A Jevtovic Dragan M Nikolic Ivan A Soldatovic | 2024 | World Journal of Diabetes2024，15，4： | 0 |
