1Laparoscopic Partial Nephrectomy With Segmental Renal Artery Clamping:Technique and Clinical Outcomes显示文摘Background:Warm ischemic injury is one of the most important factors affecting renal function in partial nephrectomy(PN).The technique of segmental renal artery clamping emerges as an alternative to conventional renal artery clamping for renal hilar control.Objective:To evaluate the feasibility and efficiency of laparoscopic PN(LPN) with segmental renal artery clamping in comparison with the conventional technique.Design,setting,and participants:A total of 75 patients underwent LPN from June 2007 to November 2009.All patients had T1a or T1b tumor in one kidney and a normal contralateral kidney.Thirty-seven patients underwent surgeries with main renal artery clamping,and 38 underwent surgeries with segmental artery clamping.Intervention:All procedures were performed by the same laparoscopic surgeon.Measurements:Blood loss,operation time,warm ischemia(WI) time,and complications affected renal function before and after operation were recorded.Results and limitations:All LPNs were completed without conversion to open surgery or nephrectomy.The novel technique slightly increased WI time(p < 0.001) and intraoperative blood loss(p = 0.006),while it provided better postoperative affected renal function(p < 0.001) compared with the conventional technique.The total complication rate was 12%.Among the 38 cases where segmental renal artery clamping was performed,7 had to convert to the conventional method.Tumor size and location influenced the number of clamped segmental arteries.Long-term postoperative renal function is still awaited.Conclusions:LPN with segmental artery clamping is safe and feasible in clinical practice.It minimizes the intraoperative WI injury and improves early postoperative affected renal function compared with main renal artery clamping.(C) 2010 European Association of Urology.Published by Elsevier B.V.All rights reserved.Shao,P.F.

4Role of antispasmodics in the treatment of irritable bowel syndrome显示文摘Irritable bowel syndrome(IBS)is a long-lasting,relapsing disorder characterized by abdominal pain/discomfort and altered bowel habits.Intestinal motility impairment and visceral hypersensitivity are the key factors among its multifactorial pathogenesis,both of which require effective treatment.Voltage-gated calcium channels mediate smooth muscle contraction and endocrine secretion and play important roles in neuronal transmission.Antispasmodics are a group of drugs that have been used in the treatment of IBS for decades.Alverine citrate,a spasmolytic,decreases the sensitivity of smooth muscle contractile proteins to calcium,and it is a selective 5-HT1A receptor antagonist.Alverine,in combination with simethicone,has been demonstrated to effectively reduce abdominal pain and discomfort in a large placebo-controlled trial.Mebeverine is a musculotropic agent that potently blocks intestinal peristalsis.Non-placebo-controlled trials have shown positive effects of mebeverine in IBS regarding symptom control;nevertheless,in recent placebo-controlled studies,mebeverine did not exhibit superiority over placebo.Otilonium bromide is poorly absorbed from the GI tract,where it acts locally as an L-type calcium channel blocker,an antimuscarinic and a tachykinin NK2receptor antagonist.Otilonium has effectively reduced pain and improved defecation alterations in placebocontrolled trials in IBS patients.Pinaverium bromide is also an L-type calcium channel blocker that acts locally in the GI tract.Pinaverium improves motility disorders and consequently reduces stool problems in IBS patients.Phloroglucinol and trimethylphloroglucinol are non-specific antispasmodics that reduced pain in IBS patients in a placebo-controlled trial.Antispasmodics have excellent safety profiles.T-type calcium channel blockers can abolish visceral hypersensitivity in animal models,which makes them potential candidates for the development of novel therapeutic agents in the treatment of IBS.Anita Annaházi Richárd Róka András Rosztóczy Tibor Wittmann 2014World Journal of Gastroenterology2014,20,20:15

7^(207)Pb/^(206)Pb Zircon Dating of the Huangtuling Hypersthene-Garnet-Biotite Gneiss from the Dabie Mountains, Luotian County, Hubei Province, China: New Evidence for Early Precambrian Evolution显示文摘The Huangtuling hypersthene-garnet-biotite gneiss at Luotian County, Hubei Provine, is a typicalgranulite-facies rock of the Dabie Group Complex in the Dabie orogenic belt. Investigations on the morphology andoccurrence of zircons and their internal structures shown in the thin sections lead to the recognition of three types ofzircons, which are in good agreement with the types identified on the basis of morphology, colour and external fea-tures from the related zircon concentrates. The observation of zircons in the rock reveals that part of type 1 zirconsshow signs of a double-layered structure. The interval part existed in the protolith prior to the granulite-facies meta-morphism. Type 2, the prismatic zircons which mainly occur in garnet and hypersthene are metamorphic minerals ofthe granulite-facies metamorphism. Type 3, the round multifaceted zircons in felsic minerals and biotite, are proba-bly attributed to a later geological event related to migmatization. The 207Pb/206Pb zircon dating by direct evaporationon (thermal evaporation ion mass spectrometer) yields ages ranging from 2814 Ma to 1992 Ma. The age discrepancyamong these different zircon types is conspicuous. The yellow-brown(type 1) zircons give ages of 2814±29 Ma to2527±6 Ma, the prismatic euhedral zircons (type 2), 2456±7 Ma to 2254±4 Ma, and the round multifaceted zircons(type 3), 1992±10 Ma. The results are geologically interpreted in consideration of the complicated behaviours of zir-cons during Precambrian geological evolution of the Dabie area. (1) If the protolith of the gneiss is a sedimentaryrock, then type 1 zircons are clastic ones and the ages 2814±29 Ma and 2811±27 Ma may reflect the minimum age ofthe rocks of its source region. also the first geological event in the area. Sedimentation of the protolith occurred be-tween 2814 Ma and 2527 Ma, probably close to 2814 Ma. If the protolith is a volcanic rock, then the formation age ofthe supracrustal rocks of the Dabie Group Complex is around 2814 Ma. The age 2456±7 Ma reflects the time whenthe granulite-facies metamorphism took place. The later migmatization event is dated at aboat 1992±10 Ma, and isprobably the latest early Precambrian event in the area. The present work provides geochronological evidence for the existence of the Dabie Archaean craton, whichhad probably experienced 3 or 4 geological events during its early Precambrian evolution.JIAN Ping YANG Weiran and ZHANG Zichao Institute of Geology,CAGS,26 Baiwanzhuang Rd, Beijing 100037 China University of Geosciences, Wuhan, Hubei 430074 Yichang Institute of Geology and Mineral Resources, CAGS, Yichang, Hubei 443003 1999Acta Geologica Sinica(English Edition)1999,73,1:12
8Early detection and prevention of pancreatic cancer:Is it really possible today?显示文摘Pancreatic cancer is the 4th leading cause of cancerrelated death in Western countries.Considering the low incidence of pancreatic cancer,population-based screening is not feasible.However,the existence of a group of individuals with an increased risk to develop pancreatic cancer has been well established.In particular,individuals suffering from a somatic or genetic condition associated with an increased relative risk of more than 5-to 10-fold seem to be suitable for enrollment in a surveillance program for prevention or early detection of pancreatic cancer.The aim of such a program is to reduce pancreatic cancer mortality through early or preemptive surgery.Considering the risk associated with pancreatic surgery,the concept of preemptive surgery cannot consist of a prophylactic removal of the pancreas in high-risk healthy individuals,but must instead aim at treating precancerous lesions such as intraductal papillary mucinous neoplasms or pancreatic intraepithelial neoplasms,or early cancer.Currently,results from clinical trials do not convincingly demonstrate the efficacy of this approach in terms of identification of precancerous lesions,nor do they define the outcome of the surgical treatment of these lesions.For this reason,surveillance programs for individuals at risk of pancreatic cancer are thus far generally limited to the setting of a clinical trial.However,the acquisition of a deeper understanding of this complex area,together with the increasing request for screening and treatment by individuals at risk,will usher pancreatologists into a new era of preemptive pancreatic surgery.Along with the growing demand to treat individuals with precancerous lesions,the need for low-risk investigation,lowmorbidity operation and a minimally invasive approach becomes increasingly pressing.All of these considerations are reasons for preemptive pancreatic surgery programs to be undertaken in specialized centers only.Marco Del Chiaro Ralf Segersvrd Matthias Lohr Caroline Verbeke 2014World Journal of Gastroenterology2014,20,34:11
9用油酸钠对赤铁矿进行剪切絮凝和浮选的研究(一)显示文摘对采用油酸钠作为选择性絮凝剂使超细(<10μm)的赤铁矿与石英分离进行了研究。影响赤铁矿絮凝物粒度的主要因素是油酸浓度、pH值、剪切速度和搅拌时间。只有当溶液中油酸的溶解度过饱和时,才能产生絮凝作用。如果在矿物颗粒周围产生油酸液滴,就会发现絮凝速度和絮凝物粒度增加。产生的赤铁矿絮凝物在300/s~2200/s的剪切速度范围内有抗破裂作用。其强度归因于碳氢链连接和疏水性的相互作用产生的引力。用油酸钠形成的疏水性絮凝物用浮选法很容易回收。含Fe15%的赤铁矿和石英混合给矿经粗选回收率达到94%,精矿品位为46%Fe。超细矿物在浮选之前进行剪切絮凝,为显著提高矿物回收率,提供了一种可能的方法。RD帕斯科 E多尔蒂 田召会 张光烈 1999国外金属矿山1999,24,1:10
10Serum positive cagA in patients with non-ulcer dyspepsia and peptic ulcer disease from two centers in different regions of Turkey显示文摘AIM: To investigate and compare frequencies of serum positive cagA in patients from two separate regions of Turkey who were grouped according to the presence of peptic ulcer disease or non-ulcer dyspepsia.METHODS: One hundred and eighty Helicobacter pyloripositive patients with peptic ulcer disease or non-ulcer dyspepsia were included in the study. One hundred and fourteen patients had non-ulcer dyspepsia and 66 had peptic ulcer disease (32 with gastric ulcers and/or erosions and 34with duodenal ulcers). Each patient was tested for serum antibody to H. pylori cagA protein by enzyme immunoassay.RESULTS: The total frequency of serum positive cagA in the study group was 97.2 %. The rates in the patients with peptic ulcers and in those with non-ulcer dyspepsia were 100% and 95.6%, respectively. These results were similar to those reported in Asian studies, but higher than those that have been noted in other studies from Turkey and Western countries.CONCLUSION: The high rates of serum positive cagA in these patients with peptic ulcer disease and non-ulcer dyspepsia were similar to results reported in Asia. The fact that there was high seroum prevalence regardless of ulcer status suggests that factors other than cagA might be responsible for ulceration or other types of severe pathology in H. pylori-positive individuals.Ender Serin Uur Yilmaz Ganiye Künefeci Birol zer Yüksel Gümürdülü Mustafa Gülü Fazilet Kayaseluk Sedat Boyaciolu 2003World Journal of Gastroenterology2003,9,4:10

16中国的寄生性杜鹃及其宿主多样性(英文)显示文摘通过多年的调查资料、观鸟爱好者所提供的图片和文献整理,我们对多杜鹃寄生系统下的中国寄生性杜鹃及其宿主的多样性进行了系统研究。在中国分布的17种寄生性杜鹃中,迄今已发现11种杜鹃的宿主达55种,均为雀形目鸟类,隶属于15科,其中莺科、鸫科和画眉科分别占到寄生记录总数的 22.6%、20.8% 和 17.0%。大杜鹃(Cuculus canorus)的宿主种类最多(45.5%),是中国最常见、宿主多样性最丰富的寄生性杜鹃。不同种类的寄生性杜鹃的卵色不同,而且杜鹃与其宿主之间均呈现明显的卵色多态性,为典型的卵色协同进化。基于人眼观察,大杜鹃、小杜鹃(C. poliocephalus)和八声杜鹃(Cacomantis merulinus)的卵色均与其宿主高度模拟,而鹰鹃(Cuculus sparverioides)、中杜鹃(C. saturatus)和翠金鹃(Chrysococcyx maculatus)则产非模拟的卵。目前仍有6种寄生性杜鹃的宿主不详,亟待加强研究。杨灿朝 梁伟 Anton ANTONOV 蔡燕 Brd G.STOKKE Frode FOSSφY Arne MOKSNES Eivin RφSKAFT 2012Chinese Birds2012,,1:5
17Epidemiologic characteristics of Helicobacter pylori infection in southeast Hungary显示文摘BACKGROUND Epidemiologic studies have revealed a decrease in the prevalence of Helicobacter pylori(H.pylori)infection in Western Europe.AIM To obtain data regarding the prevalence of H.pylori in Csongrád and Békés Counties in Hungary,evaluate the differences in its prevalence between urban and rural areas,and establish factors associated with positive seroprevalence.METHODS One-thousand and one healthy blood donors[male/female:501/500,mean age:40(19–65)years]were enrolled in this study.Subjects were tested for H.pylori IgG antibody positivity via enzyme-linked immunosorbent assay.Subgroup analysis by age,gender,smoking habits,alcohol consumption,and urban vs nonurban residence was also performed.RESULTS The overall seropositivity of H.pylori was 32%.It was higher in males(34.93%vs 29.2%,P=0.0521)and in rural areas(36.2%vs 27.94%,P=0.0051).Agricultural/industrial workers were more likely to be positive for infection than office workers(38.35%vs 30.11%,P=0.0095)and rural subjects in Békés County than those in Csongrád County(43.36%vs 33.33%,P=0.0015).CONCLUSION Although the prevalence of H.pylori infection decreased in recent decades in Southeast Hungary,it remains high in middle-aged rural populations.Generally accepted risk factors for H.pylori positivity appeared to be valid for the studied population.Lenke Bálint Andrea Tiszai Gábor Kozák Ilona Dóczi Veronika Szekeres Orsolya Inczefi Georgina Ollé Krisztina Helle Richárd Róka András Rosztóczy 2019World Journal of Gastroenterology2019,25,42:5
