2聚合酶链反应检测乙型肝炎患者肝外组织中的乙型肝炎病毒DNA显示文摘应用巢式聚合酶链(PCR)技术对18例石蜡包埋的胆囊、肾、脾、肾上腺、心、睾丸、胰腺及肝脏组织的乙型肝炎病毒(HBV)DNA进行了检测,并与其免疫组化及原位杂交方法作比较。二组引物检测的结果表明:肝组织中均有HBV感染,其中5例有HBV的复制。肝外组织中HBV检出率分别为胆囊85.7%、75.0%、肾72.7%、肾上腺66.7%、心脏55.6%、睾丸55.6%和胰腺54.5%,但均未检测出HBV的复制,PCR检测发现与免疫组化及原位杂交结果基本一致。HBV可以感染肝外组织但并不在这些组织中复制的发现可以解释受感染的肝外组织可以作为肝外感染源,但并不引起这些脏器出现明显的病理变化。郎振为 闫惠平 黄德在 王健 吴和 Zhang JL Perry A Byrne SK Stiver GH 1994中华内科杂志1994,33,4:33
3Vasculogenic mimicry is a prognostic factor for postoperative survival in patients with glioblastoma显示文摘A previous report has confirmed the existence and clinical significance of vasculogenic mimicry(VM)in glioma.However,its conclusions about the negative clinical significance of VM in glioblastoma are based on a small group of patients and,thus,might be unconvincing.The aim of the present study was to reevaluate the clinical significance of VM in glioblastoma.Patients were classified as VM-positive orWang SY Ke YQ Lu GH Song ZH Yu L Xiao S Sun XL Jiang XD Yang ZL Hu CC 2013中国神经肿瘤杂志2013,11,3:22
4改良乳房下真皮乳腺单蒂瓣巨乳缩小术显示文摘目的为了进一步保证巨乳缩小术后乳头乳晕的血供和感觉,减少手术并发症。方法设计应用乳房下真皮单蒂瓣,并保留部分乳腺组织的垂直乳腺蒂,及切除的乳腺组织位于乳房下方两侧的巨乳缩小术,自1994年1月至1995年11月,为67例(132侧)巨乳患者在法国斯德拉斯堡欧洲美容整形诊所进行治疗。结果术后全部患者无乳头乳晕并发症,感觉正常。结论结合乳腺垂直蒂和乳房下真皮单蒂瓣的改良巨乳缩小术,不但可以确保乳头乳晕的血供,且可减少感觉损伤,降低手术并发症,及提供良好形态。马海欢 Muller GH 1998中华整形烧伤外科杂志1998,14,1:20
5聚合酶链反应检测乙型肝炎患者心肌组织中 HBV DNA显示文摘应用巢式聚台酶链反应(PCR)技术检测了18例乙型肝炎(乙肝)患者石蜡包埋心、肝组织中的HBVDNA,并与其免疫组化及原位杂交结果作了比较。二组引物检测的结果表明:在肝组织中均有HBV感染,其中5例有HBV复制。心肌组织HBVDNA的检出率为55.6%,不存在HBV的复制。心脏病理检查可见一些非特异性改变,如脂变、水肿和纤维素样坏死等。病理变化与心电图、临床症状、体征及PCR检测结果无相关件。以上结果提示:乙肝患者心脏出现的一些病变可能是由于沉积于心肌内的免疫复合物介导损伤的结果。郎振为 阎惠平 李俊强 Zhang JL Perry A Byrne SK Stiver GH 1994中华传染病杂志1994,12,1:19
6Prediction of uniaxial compressive strength and modulus of elasticity for Travertine samples using regression and artificial neural networks显示文摘Uniaxial Compressive Strength (UCS) and modulus of elasticity (E) are the most important rock parameters required and determined for rock mechanical studies in most civil and mining projects. In this study, two mathematical methods, regression analysis and Artificial Neural Networks (ANNs), were used to predict the uniaxial compressive strength and modulus of elasticity. The P-wave velocity, the point load index, the Schmidt hammer rebound number and porosity were used as inputs for both meth-ods. The regression equations show that the relationship between P-wave velocity, point load index, Schmidt hammer rebound number and the porosity input sets with uniaxial compressive strength and modulus of elasticity under conditions of linear rela-tions obtained coefficients of determination of (R2) of 0.64 and 0.56, respectively. ANNs were used to improve the regression re-sults. The generalized regression and feed forward neural networks with two outputs (UCS and E) improved the coefficients of determination to more acceptable levels of 0.86 and 0.92 for UCS and to 0.77 and 0.82 for E. The results show that the proposed ANN methods could be applied as a new acceptable method for the prediction of uniaxial compressive strength and modulus of elasticity of intact rocks.DEHGHAN S SATTARI Gh CHEHREH CHELGANI S ALIABADI M A 2010Mining Science and Technology2010,20,1:18
7Ehealth:Low FODMAP diet vs Lactobacillus rhamnosus GG in irritable bowel syndrome显示文摘AIM:To investigate the effects of a low fermentable,oligosaccharides,disaccharides,monosaccharides and polyols diet(LFD)and the probiotic Lactobacillus rhamnosus GG(LGG)in irritable bowel syndrome(IBS).METHODS:Randomised,unblinded controlled trial on the effect of 6-wk treatment with LFD,LGG or a normal Danish/Western diet(ND)in patients with IBS fulfilling Rome III diagnostic criteria,recruited betweenNovember 2009 and April 2013.Patients were required to complete on a weekly basis the IBS severity score system(IBS-SSS)and IBS quality of life(IBS-QOL)questionnaires in a specially developed IBS web selfmonitoring application.We investigated whether LFD or LGG could reduce IBS-SSS and improve QOL in IBS patients.RESULTS:One hundred twenty-three(median age 37years,range:18-74 years),90(73%)females were randomised:42 to LFD,41 to LGG and 40 to ND.A significant reduction in mean±SD of IBS-SSS from baseline to week 6 between LFD vs LGG vs ND was revealed:133±122 vs 68±107,133±122 vs 34±95,P<0.01.Adjusted changes of IBS-SSS for baseline covariates showed statistically significant reduction of IBS-SSS in LFD group compared to ND(IBS-SSS score75;95%CI:24-126,P<0.01),but not in LGG compared to ND(IBS-SSS score 32;95%CI:18-80,P=0.20).IBS-QOL was not altered significantly in any of the three groups:mean±SD in LFD 8±18 vs LGG 7±17,LFD 8±18 vs ND 0.1±15,P=0.13.CONCLUSION:LFD is efficacious for patients with IBS.Natalia Pedersen Nynne Nyboe Andersen Zsuzsanna Végh Lisbeth Jensen Dorit Vedel Ankersen Maria Felding Mette Hestetun Simonsen Johan Burisch Pia Munkholm 2014World Journal of Gastroenterology2014,20,43:16
8Low-FODMAP diet reduces irritable bowel symptoms in patients with inflammatory bowel disease显示文摘AIM To investigate the effect of a low-FODMAP diet on irritable bowel syndrome(IBS)-like symptoms in patients with inflammatory bowel disease(IBD).METHODS This was a randomised controlled open-label trial of patients with IBD in remission or with mild-to-moderate disease and coexisting IBS-like symptoms(Rome III) randomly assigned to a Low-FODMAP diet(LFD) or a normal diet(ND) for 6 wk between June 2012 andDecember 2013. Patients completed the IBS symptom severity system(IBS-SSS) and short IBD quality of life questionnaire(SIBDQ) at weeks 0 and 6. The primary end-point was response rates(at least 50-point reduction) in IBS-SSS at week 6 between groups; secondary end-point was the impact on quality of life. RESULTS Eighty-nine patients, 67(75%) women, median age 40, range 20-70 years were randomised: 44 to LFD group and 45 to ND, from which 78 patients completed the study period and were included in the final analysis(37 LFD and 41 ND). There was a significantly larger proportion of responders in the LFD group(n = 30, 81%) than in the ND group(n = 19, 46%);(OR = 5.30; 95%CI: 1.81-15.55, P < 0.01). At week 6, the LFD group showed a significantly lower median IBSSSS(median 115; inter-quartile range [IQR] 33-169) than ND group(median 170, IQR 91-288), P = 0.02. Furthermore, the LFD group had a significantly greater increase in SIBDQ(median 60, IQR 51-65) than the ND group(median 50, IQR 39-60), P < 0.01.CONCLUSION In a prospective study, a low-FODMAP diet reduced IBS-like symptoms and increased quality of life in patients with IBD in remission.Natalia Pedersen Dorit Vedel Ankersen Maria Felding Henrik Wachmann Zsuzsanna Végh Line Molzen Johan Burisch Jens Rikardt Andersen Pia Munkholm 2017World Journal of Gastroenterology2017,23,18:15

10Cyclooxygenase-2 polymorphisms and the risk of esophageal adeno-or squamous cell carcinoma显示文摘AIM:To determine whether-1195 A→G and/or-765 G→C polymorphisms in Cyclooxygenase-2(COX-2 ) may have a risk modifying effect on the development of esophageal carcinoma in a Dutch Caucasian population.METHODS:Two study groups were recruited, 252 patients with esophageal carcinoma and 240 healthy controls, matched for race, age, gender and recruiting area.DNA was isolated from whole blood and used for genotyping.PCR products were digested with restriction enzymes and products were analyzed by agarose gel electrophoresis.Odds ratios(OR) and 95% confldence intervals(CI) were estimated.RESULTS:The distribution of the-1195 A→G polymorphism was signif icantly different in esophageal cancer patients compared to controls.The-1195 GG genotype resulted in a higher risk of developing esophageal adenocarcinoma(OR = 3.85, 95% CI:1.45-10.3) compared with the-1195 AA genotype as a reference.The-765 G→C genotype distribution was not different between the two groups.The GG/ GG haplotype was present more often in esophageal adenocarcinoma patients than in controls(OR = 3.45, 95% CI:1.24-9.58;with AG/AG as a reference).The same trends were observed in patients with squamous cell carcinomas, however, the results did not reach statistical signif icance.CONCLUSION:Presence of the COX-2-1195 GG genotype and of the GG/GG haplotype may result in a higher risk of developing esophageal carcinoma.Jón O Kristinsson Paul van Westerveld Rene HM te Morsche Hennie MJ Roelofs T Wobbes Ben JM Witteman Adriaan CITL Tan Martijn GH van Oijen Jan BMJ Jansen Wilbert HM Peters 2009World Journal of Gastroenterology2009,15,28:11
11Follow-up of patients with functional bowel symptoms treated with a low FODMAP diet显示文摘AIM: To investigate patient-reported outcomes from, and adherence to, a low FODMAP diet among patients suffering from irritable bowel syndrome and inflammatory bowel disease.METHODS: Consecutive patients with irritable bowel syndrome(IBS) or inflammatory bowel disease(IBD) and co-existing IBS fulfilling the ROME Ⅲ criteria, who previously attended an outpatient clinic for low FODMAP diet(LFD) dietary management and assessment by a gastroenterologist, were invited to participate in a retrospective questionnaire analysis. The questionnaires were sent and returned by regular mail and gathered information on recall of dietarytreatment, efficacy, symptoms, adherence, satisfaction, change in disease course and stool type, and quality of life. Before study enrolment all patients had to sign an informed written consent.RESULTS: One hundred and eighty patients were included, 131(73%) IBS and 49(27%) IBD patients. Median age was 43 years(range: 18-85) and 147(82%) were females. Median follow-up time was 16 mo(range: 2-80). Eighty-six percent reported either partial(54%) or full(32%) efficacy with greatest improvement of bloating(82%) and abdominal pain(71%). The proportion of patients with full efficacy tended to be greater in the IBD group than in the IBS group(42% vs 29%, P = 0.08). There was a significant reduction in patients with a chronic continuous disease course in both the IBS group(25%, P < 0.001) and IBD group(23%, P = 0.002) along with a significant increase in patients with a mild indolent disease course of 37%(P < 0.001) and 23%(P = 0.002), respectively. The proportion of patients having normal stools increased with 41% in the IBS group(P < 0.001) and 66% in the IBD group(P < 0.001). One-third of patients adhered to the diet and high adherence was associated with longer duration of dietary course(P < 0.001). Satisfaction with dietary management was seen in 83(70%) IBS patients and 24(55%) IBD patients. Eightyfour percent of patients lived on a modified LFD, where some foods rich in FODMAPs were reintroduced, and 16% followed the LFD by the book without deviations. Wheat, dairy products, and onions were the foods most often not reintroduced by patients.CONCLUSION: These data suggest that a diet low in FODMAPs is an efficacious treatment solution in the management of functional bowel symptoms for IBS and IBD patients.Louise Maagaard Dorit V Ankersen Zsuzsanna Végh Johan Burisch Lisbeth Jensen Natalia Pedersen Pia Munkholm 2016World Journal of Gastroenterology2016,22,15:8

16Split-dose or hybrid nonsteroidal anti-inflammatory drugs and Nacetylcysteine therapy for prevention of post-retrograde cholangiopancreatography pancreatitis显示文摘BACKGROUND Despite significant technical and training improvements, the incidence of postendoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP) has not significantly dropped. Although many studies have evaluated the efficacy of various agents, e.g. nonsteroidal anti-inflammatory drugs, octreotide,antioxidants, administered via various dosages, routes(oral, intrarectal or parenteral), and schedules(before or after the procedure), the results have been conflicting.AIM To evaluate efficacy of three pharmacologic prophylactic methods for prevention of PEP.METHODS In this prospective, single-center randomized trial, patients who underwent firsttime ERCP for choledocholithiasis were randomly assigned to three groups. The first group received 600 mg N-acetylcysteine 15 min prior to ERCP, and perrectum administration of 50 mg indomethacin both prior to and after completion of the ERCP. The second group was administered only the 50 mg indomethacin per-rectum both prior to and after the ERCP. The third group was administeredper-rectum 100 mg indomethacin only after the ERCP, representing the control group given the guideline-recommended regimen. The primary end-point was PEP prevention.RESULTS Among the total 211 patients evaluated during the study, 186 fulfilled the inclusion criteria and completed the protocol. The percentages of patients who developed PEP in each of the three groups were not significantly different(χ2 =2.793, P = 0.247). Among the acute PEP cases, for all groups, 14 patients developed mild pancreatitis(77.77%) and 4 moderate. No severe cases of PEP occurred, and in all PEP cases the resolution was favorable. No adverse events related to the medications(digestive hemorrhage, rectal irritation, or allergies)occurred.CONCLUSION The efficacies of split-dose indomethacin and combined administration(Nacetylcysteine with indomethacin) for preventing PEP were similar to that of the standard regimen.Laura Pavel Gheorghe Gh Balan Alexandra Nicorescu Georgiana Emmanuela Gilca-Blanariu Catalin Sfarti Stefan Chiriac Smaranda Diaconescu Vasile Liviu Drug Gheorghe Balan Gabriela Stefanescu 2019World Journal of Clinical Cases2019,7,3:3
