| 1 | Colonoscopic yield of colorectal neoplasia in daily clinical practice显示文摘AIM:To assess the prevalence and location of ad-vanced neoplasia in patients undergoing colonoscopy,and to compare the yield per indication.METHODS:In a multicenter colonoscopy survey (n = 18 hospitals) in the Amsterdam area (Northern Holland),data of all colonoscopies performed during a three month period in 2005 were analyzed. The location and the histological features of all colonic neoplasia were recorded. The prevalence and the distribution ofadvanced colorectal neoplasia and differences in yield between indication clusters were evaluated. Advanced neoplasm was defi ned as adenoma > 10 mm in size,with > 25% villous features or with high-grade dyspla-sia or cancer.RESULTS:A total of 4623 eligible patients underwent a total colonoscopy. The prevalence of advanced neo-plasia was 13%,with 281 (6%) adenocarcinomas and 342 (7%) advanced adenomas. Sixty-seven percent and 33% of advanced neoplasia were located in the distal and proximal colon,respectively. Of all patients with right-sided advanced neoplasia (n = 228),51% had a normal distal colon,whereas 27% had a syn-chronous distal adenoma. Ten percent of all colono-scopies were performed in asymptomatic patients,7% of whom had advanced neoplasia. In the respective procedure indication clusters,the prevalence of right-sided advanced neoplasia ranged from 11%-57%. CONCLUSION:One out of every 7-8 colonoscopies yielded an advanced colorectal neoplasm. Colonoscopy is warranted for the evaluation of both symptomatic and asymptomatic patients. | Jochim S Terhaar sive Droste Mike E Craanen Rene WM van der Hulst Joep F Bartelsman Dick P Bezemer Kim R Cappendijk Gerrit A Meijer Linde M Morsink Pleun Snel Hans ARE Tuynman Roy LJ van Wanrooy Eric IC Wesdorp Chris JJ Mulder | 2009 | World Journal of Gastroenterology2009，15，9： | 6 |
| 2 | Utilization of Thermally Treated Flue Gas Desulfurization (FGD) Gypsum and Class-C Fly Ash (CFA) to Prepare CFA-Based Geopolymer显示文摘The feasibility of utilization of flue gas desulfurization (FGD) gypsum and Class-C fly ash (CFA) to prepare CFA-based geopolymer were studied. The results showed that geopolymer made from 90% CFA and 10% FGD gypsum (FGDG) which was thermally treated at 800 ℃ for 1 h obtained the better compressive strength of 37.0 MPa. The micro characteristics and structures of the geopolymer samples of CFA and CFA-FGDG were tested by XRD, FT-IR, and SEM-EDXA after these samples cured at 75 ℃ for 8 h followed by 23 ℃ for 28 d. Both the geopolymer samples of CFA and CFA-FGDG have significant asymmetric stretching of Al-O/Si-O bonds and Si-O-Si / Si-O-Al bending band. In geopolymer sample of CFA-FGDG, a small quantity of lathy products probably being the ettringite wrapped over the spherical fly ash particle, and the concentration of sulfur is much more than that in geopolymer sample of CFA. It is indicated that FGD gypsum may react during alkali-activated and geopolymeric process. | 郭晓潞 施惠生 Warren A Dick | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，1： | 3 |

| 4 | Misdiagnosis of tuberculosis and the clinical relevance of nontuberculous mycobacteria in Zambia显示文摘Objective:To determine the accuracy of TB diagnosis of TB in Zambia in the era of increasing HIV prevalence.Methods:Sputum of the clinically diagnosed TB cases was additionally subjected to liquid culture and molecular identification.This study distinguished between TB cases confirmed by positive Mycobacterium tuberculosis(M.tuberculosis) cultures and mycobacterial disease caused by non-tuberculous mycobacteria(NTM).Results:Only 49% of the 173 presumptively diagnosed TB cases was M.tuberculosis cultured,while in 13% (22) cases,a combination of M.tuberculosis and NTM was found.In 18% of the patients only NTM were cultured.In 28% ,no mycobacteria was cultivable.HIV positive status was correlated with the isolation of NTM(P<0.05).Conclusions:The diagnosis of tuberculosis based on symptoms, sputum smear and/or chest X-ray leads to significant numbers of false-positive TB cases in Zambia,most likely due to the increased prevalence of HIV.The role of NTM in tuberculosislike disease also seems relevant to the false diagnosis of TB in Zambia. | Patricia CAM Buijtels Michael D Iseman Shelagh Parkinson Cas S de Graaff Henri A Verbrugh Pieter LC Petit Dick van Soolingen | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，5： | 2 |
| 5 | D-MELD risk capping improves post-transplant and overall mortality under markov microsimulation显示文摘AIM: To hypothesize that the product of calculated Model for End-Stage Liver Disease score excluding exception points and donor age(D-MELD) risk capping ± Rule 14 could improve post liver transplant and overall survival after listing.METHODS: Probabilities derived from the United Network for Organ Sharing database between 2002 and 2004 were used to simulate potential outcomes for all patients listed for transplantation. The Markov simula-tion was then modified by screening matches using a 1200 or 1600 D-MELD risk cap ± allowing transplants for Model for End-Stage Liver Disease(MELD) ≤ 14(Rule 14). The differential impact of the rule changes was assessed.RESULTS: The Markov simulation accurately reproduced overall and post transplant survival. A 1200 D-MELD risk cap improved post-transplant survival. Both the 1200 and 1600 risk caps improved overall survival for waitlisted patients. The addition of Rule 14 further improved post transplant and overall survival by redistribution of donor livers to recipients in higher MELD subgroups. The mechanism for improved overall and post-transplant survival after listing was due to shifting a larger percentage of transplants to the moderate MELD score subgroup(MELD 15-29) while also ensuring that high MELD recipients have livers of high quality to achieve excellent post transplant survival.CONCLUSION: A 1200 D-MELD risk cap + Rule 14 provided the greatest overall benefit primarily by focusing liver transplantation towards the moderate MELD recipient. | Jeffrey B Halldorson Robert L Carithers Jr Renuka Bhattacharya Ramasamy Bakthavatsalam Iris W Liou Andre A Dick Jorge D Reyes James D Perkins | 2014 | World Journal of Transplantation2014，4，3： | 2 |
