1Primary gastric mucosa associated lymphoid tissue lymphoma: Clinical data predicted treatment outcome显示文摘AIM: To determine clinical characteristics and treatment outcome of gastric lymphoma after chemotherapy and immuno-chemotherapy. METHODS: Thirty four patients with primary gastric mucosa associated lymphoid tissue (MALT) lymphoma (Ann Arbor stages Ⅰ to Ⅳ) were enrolled. All had upper gastric endoscopy, abdominal ultrasonography, CT and H pylori status assessment (histology and serology). After anti-H pylori treatment and initial chemotherapy, patients were re-examined every 4 mo. RESULTS: Histological regression of the lymphoma was complete in 22/34 (64.7%) and partial in 9 (26.5%) patients. Median follow up time for these 31 responders was 60 mo (range 48-120). No regression was noted in 3 patients. Among the 25 (73.5%) H pylori positive patients, the eradication rate was 100%.CONCLUSION: Using univariate analysis, predictive factors for overall survival were international prognostic index (IPI) score, hemoglobin level, erythrocyte sedimentation rate (ESR), and platelet numbers (P < 0.005). In addition to this, Cox proportion hazard model differentiate IPI score, ESR, and platelets as predictors of survival.Milena Todorovic Bela Balint Miodrag Jevtic Nada Suvajdzic Amela Ceric Dragana Stamatovic Olivera Markovic Maja Perunicic Slobodan Marjanovic Miodrag Krstic 2008World Journal of Gastroenterology2008,14,15:10
2Preventive effect of a pectic polysaccharide of the common cranberry Vaccinium oxycoccos L. on acetic acid-induced colitis in mice显示文摘AIM: To study isolation and chemical characterization of pectin derived from the common cranberry Vaccinium oxycoccos L. (oxycoccusan OP) and the testing of its preventive effect on experimental colitis.METHODS: Mice were administrated orally with OP two days prior to a rectal injection of 5% acetic acid and examined for colonic damage 24 h later. Colonic inflammation was characterized by macroscopical injury and enhanced levels of myeloperoxidase activity measured spectrophotometrically with o-phenylene diamine as the substrate. The mucus contents of the colon were determined by the Alcian blue dye binding method. Vascular permeability was estimated using 4% Evans blue passage after i.p. injection of 0.05 mol/L acetic acid. RESULTS: In the mice treated with OP, colonic macroscopic scores (1.1 ± 0.4 vs 2.7, P < 0.01) and the total square area of damage (10 ± 2 vs 21 ± 7, P < 0.01) were significantly reduced when compared with the vehicle-treated colitis group. OP was shown to decrease the tissue myeloperoxidase activity in colons (42 ± 11 vs 112 ± 40, P < 0.01) and enhance the amount of mucus of colitis mice (0.9 ± 0.1 vs 0.4 ± 0.1, P < 0.01). The level of colonic malondialdehyde was noted to decrease in OP-pretreated mice (3.6 ± 0.7 vs 5.1 ± 0.8, P < 0.01). OP was found to decrease the inflammatory status of mice as was determined by reduction of vascular permeability (161 ± 34 vs 241 ± 21, P < 0.01). Adhesionof peritoneal neutrophils and macrophages was also shown to decrease after administration of OP (141 ± 50 vs 235 ± 37, P < 0.05).CONCLUSION: Thus, a preventive effect of pectin from the common cranberry, namely oxycoccusan OP, on acetic acid-induced colitis in mice was detected. A reduction of neutrophil infiltration and antioxidant action may be implicated in the protective effect of oxycoccusan.Sergey V Popov Pavel A Markov Ida R Nikitina Sergey Petrishev Vasily Smirnov Yury S Ovodov 2006World Journal of Gastroenterology2006,12,41:9
3羟基磷灰石陶瓷诱导成骨细胞的研究显示文摘通过定量检测在羟基磷灰石(HA)表面生长的成骨细胞骨涎蛋白和骨钙蛋白的表达,研究了羟基磷灰石陶瓷对成骨细胞的影响.研究结果表明,随着成骨细胞培养时间的延长,在羟基磷灰石表面生长的成骨细胞骨钙蛋白和骨涎蛋白的表达量相对于对照组有显著增加.由于骨钙蛋白和骨涎蛋白是成骨细胞分化晚期高度表达的两种标志性蛋白质,因此其表达量的显著提高意味着羟基磷灰石陶瓷可以诱导成骨细胞的成熟.这一结果可进一步为理解HA陶瓷的生物相容性和生物活性提供分子生物学依据.王朝元 段友容 Boban Markovic C.

4现有防疫通风措施及基于先进气流组织的源头控制技术应用显示文摘新冠疫情暴发后,如何应对呼吸道传染病的传播这一难题再次摆在了人们面前.通风是最重要的工程防疫措施,ASHRAE、REHVA、SHASE以及中国的相关机构、学会就如何利用暖通空调系统有效防控COVID-19的传播相继出台了指导性文件.总结和分析系列指导性文件中有关通风量和气流组织方面的内容,发现现有工程防疫措施尚存在诸多需改进之处.传统的全空间通风在疫情期间表现出通风量不足、对近距离短期暴露事件效率低下、能耗高等缺陷,而基于先进气流组织的源头控制技术具有控制效率高、个性化可调、响应快速且节能潜力大等优势,恰好可弥补全空间通风的不足.在此基础上,系统地总结了基于先进气流组织的源头控制措施在呼吸道传染病传播控制方面的技术类型,并考虑到后疫情时代通风系统设计面临以“平疫结合”为导向的发展趋势,探讨了在“平疫结合”中应用源头控制技术的优势,以及在一些高风险场景应用源头控制从而实现“平疫结合”的技术路线,并分析了为落实“平疫结合”设计理念所需进一步探索的技术方向.所做探索预期为后续指南的编撰提供参考,为未来防疫通风设计带来新思路和新启示.艾正涛 叶金军 MELIKOV A K MARKOV D G 2022湖南大学学报(自然科学版)2022,49,5:6
5Metabolic syndrome attenuates ulcerative colitis: Correlation with interleukin-10 and galectin-3 expression显示文摘BACKGROUND Ulcerative colitis(UC)is a chronic disease characterized by inflammation of intestinal epithelium,primarily of the colon.An increasing prevalence of metabolic syndrome(MetS)in patients with UC has been documented recently.Still,there is no evidence that MetS alters the course of the UC.AIM To test the influence of the MetS on the severity of UC and the local and systemic immune status.METHODS Eighty nine patients with de novo histologically confirmed UC were divided in two groups,according to ATP III criteria:Group without MetS(no MetS)and group with MetS.RESULTS Clinically and histologically milder disease with higher serum level of immunosuppressive cytokine interleukin-10(IL-10)and fecal content of Galectin-3(Gal-3)was observed in subjects with UC and MetS,compared to subjects suffering from UC only.This was accompanied with predomination of IL-10 over pro-inflammatory cytokines tumor necrosis factorα(TNF-α),interleukin-6(IL-6),and interleukin-17(IL-17)in the sera as well as Gal-3 over TNF-αand IL-17 in feces of UC patients with MetS.Further,the patients with both conditions(UC and MetS)had higher percentage of IL-10 producing and Gal-3 expressing innate and acquired immune cells in lamina propria.CONCLUSION Local dominance of Gal-3 and IL-10 over pro-inflammatory mediators in patients with MetS may present a mechanism for limiting the inflammatory process and subsequent tissue damage in UC.Marina Jovanovic Bojana Simovic Markovic Nevena Gajovic Milena Jurisevic Aleksandar Djukic Ivan Jovanovic Nebojsa Arsenijevic Aleksandra Lukic Natasa Zdravkovic 2019World Journal of Gastroenterology2019,25,43:5
6Pyridine Nucleotide Cycling and Control of Intracellular Redox State in Relation to Poly (ADP-Ribose) Polymerase Activity and Nuclear Localization of Glutathione during Exponential Growth of Arabidopsis Cells in Culture显示文摘Pyridine 核苷酸, ascorbate 和谷胱甘肽是在植物房间的主要氧化还原作用代谢物,与在细胞的氧化还原作用动态平衡和房间周期的规定的特定的角色。然而,代谢物在指数的生长期间分享的这些的规定和他们在细胞周期的精确功能尚待被描绘。在在文化的 Arabidopsis 房间的指数的生长期间的许多 ascorbate,谷胱甘肽,和 pyridine 核苷酸的现在的分析为每这些氧化还原作用水池的微分规定提供证据。Ascorbate 早很充满生长周期,但是谷胱甘肽在这个点是低的。到 dehydroascorbate 的细胞的 ascorbate 和到谷胱甘肽二硫化物比率的减少的谷胱甘肽(GSH ) 高、不变,但是 pyridine 核苷酸分享大部分在指数的生长的时期上被氧化并且一旦生长停止了,仅仅变得更多减少。谷胱甘肽水池增加了与同时 poly (自动数据处理核糖) 聚合酶(PARP ) 活动并且一次由 transcriptome 信息是的高房间周期活动随许多 PARP1 和 PARP2 mRNAs 的增加显示了。在在细胞质和原子核之间的 GSH 的细胞内部的划分的显著变化被观察。由冲淡的指数的生长阶段的扩展或改变导致的媒介在谷胱甘肽和菸碱腺嘌 dinucleotide 增加,氧化形式( NAD ) -plus-nicotinamide 腺嘌 dinucleotide ,减少的形式( NADH )水池并且到更高的 NAD/NADH 比率但是菸碱腺嘌 dinucleotide 磷酸盐,氧化形式( NADP ) -plus-nicotinamide 腺嘌 dinucleotide 磷酸盐,减少的形式( NADPH )水池尺寸,和 NAPD/NADPH 比率是影响的少得多。在指数的生长阶段结束了以前, ascorbate,谷胱甘肽,和 pyridine 核苷酸水池和 PARP 活动减少了。我们断定在生长周期期间处于细胞内部的氧化还原作用状态有显著变化,但是氧化还原作用动态平衡被主要氧化还原作用 pyridine 核苷酸,谷胱甘肽,和 ascorbate 水池的相互影响维持。在 PARP 表示和活动和 GSH 累积并且发现那 GSH 能被招募到原子核之间的关联建议在氧化还原作用规定和原子酶活动之间的一种关系。Till K.

9Adenosquamous carcinoma arising within a retrorectal tailgut cyst: Report of a case显示文摘Retrorectal, developmental tail gut cysts, include dermoid cysts, rectal duplication cysts and retrorectal cyst-hamartomas. Retrorectal cyst-hamartomas (RCH) are derived from remnants of the tail gut, the most caudal part of the embryonic hind gut, which normally involutes by the 8th wk of embryonic development (3-8 mm stage). They have specific radiological and histopathological features that distinguish them from other similar formations (dermoid cysts, enteric duplication cysts and teratomas). We report a patient with adenosquamous carcinoma arising within RCH, who underwent complete resection of the cyst through anterior laparotomy, and reached complete (recurrencefree for 14 mo, so far) functional recovery. The cyst was incidentally discovered during hysterectomy 12 years ago.Diagnostic, therapeutic and histopathological aspects of this rare case are discussed. The mentioned period between diagnosis and surgical treatment suggests that RCH, given enough time, can develop malignant degeneration, and should be resected at the time of diagnosis.Zoran Krivokapic Ivan Dimitrijevic Goran Barisic Velimir Markovic Miodrag Krstic 2005World Journal of Gastroenterology2005,11,39:2
