1Clinical outcome and predictors of survival after TIPS insertion in patients with liver cirrhosis显示文摘AIM:To determine the clinical outcome and predictors of survival after transjugular intrahepatic portosystemic stent shunt (TIPS) implantation in cirrhotic patients. METHODS:Eighty-one patients with liver cirrhosis and consequential portal hypertension had TIPS implantation (bare metal) for either refractory ascites (RA) (n= 27) or variceal bleeding (VB) (n = 54). Endpoints for the study were:technical success, stent occlusion and stent stenosis, rebleeding, RA and mortality. Clinical records of patients were collected and analysed. Baseline characteristics [e.g., age, sex, CHILD score and the model for end-stage liver disease score (MELD score), underlying disease] were retrieved. The Kaplan-Meier method was employed to calculate survival from the time of TIPS implantation and comparisons were made by log rank test. A multivariate analysis of factors influencing survival was carried out using the Cox proportional hazards regression model. Results were expressed as medians and ranges. Comparisons between groups were performed by using the Mann-Whitney Utest and the χ 2 test as appropriate. RESULTS:No difference could be seen in terms of age, sex, underlying disease or degree of portal pressure gradient (PPG) reduction between the ascites and the bleeding group. The PPG significantly decreased from 23.4 ± 5.3 mmHg (VB) vs 22.1 ± 5.5 mmHg (RA) before TIPS to 11.8 ± 4.0 vs 11.7 ± 4.2 after TIPS implantation (P = 0.001 within each group). There was a tendency towards more patients with stage CHILD A in the bleeding group compared to the ascites group (24 vs 6, P = 0.052). The median survival for the ascites group was 29 mo compared to > 60 mo for the bleeding group (P = 0.009). The number of radiological controls for stent patency was 6.3 for bleeders and 3.8 for ascites patients (P = 0.029). Kaplan-Meier calculation indicated that stent occlusion at first control (P = 0.027), ascites prior to TIPS implantation (P = 0.009), CHILD stage (P = 0.013), MELD score (P = 0.001) and those patients not having undergone liver transplantation (P = 0.024) were significant predictors of survival. In the Cox regression model, stent occlusion (P = 0.022), RA (P = 0.043), CHILD stage (P = 0.015) and MELD score (P = 0.004) turned out to be independent prognostic factors of survival. The anticoagulation management (P = 0.097), the porto-systemic pressure gradient (P= 0.460) and rebleeding episodes (P = 0.765) had no significant effect on the overall survival. CONCLUSION:RA, stent occlusion, initial CHILD stage and MELD score are independent predictors of survival in patients with TIPS, speaking for a close follow-up in these circumstances.Hauke S Heinzow Philipp Lenz Michael Khler Frank Reinecke Hansjrg Ullerich Wolfram Domschke Dirk Domagk Tobias Meister 2012World Journal of Gastroenterology2012,18,37:17

4Transcutaneous perianal sonography:A sensitive method for the detection of perianal inflammatory lesions in Crohn's disease显示文摘AIM: Pelvic magnetic resonance imaging (MRI) and endoanalultrasound which are established imaging methods forperianal inflammatory lesions in patients with Crohn'sdisease require expensive specialized equipments andexpertise. We investigated the feasibility and sensitivity oftranscutaneous perianal ultrasound (PAUS) using regularultrasound probes in the imaging of perianal inflammatorylesions. The sonographic findings were correlated to pelvicMRI-scans.METHODS: We performed PAUS in 25 patients with Crohn'sdisease and clinical signs of perianal inflammatory disease.VCChin a median of 10 d (range 0-75) these patients underwentMRI of the pelvis. Regular convex and linear high resolutionprobes were used for PAUS. The sonographic findings werecorrelated to the MRI findings by blinded investigators.RESULTS: The sonographic investigations were welltolerated by all patients. Fistulae typically presented ashypoechoic tracks. Twenty-nine fistulae were detected in22 patients. Abscesses were detected in 7 patients andpresented as hypo- or anechoic formations. Twenty-six of29 fistulae and 6 of 7 abscesses could be confirmed byMRI. Kappa statistics showed an excellent agreement(kappa>0.83) between the two imaging methods.CONCLUSION: PAUS is a simple, painless, feasible, real-time method that can be performed without specific patientpreparation which is comparable in its sensitivity to pelvicMRI in the detection of perianal fistulae and/or abscesses.PAUS can especially be recommended as a screening toolin acute perianal disorders such as perianal abscess andfor follow-up studies of perianal inflammatory disease.Jochen Wedemeyer Timm Kirchhoff Gernot Sellge Oliver Bachmann Joachim Lotz Michael Galanski Michael P.Manns Michael J.Gebel Jrg S.Bleck 2004World Journal of Gastroenterology2004,10,19:8

6Effects of sleep bruxism on functional and occlusal parameters:a prospective controlled investigation显示文摘This study was conducted to verify the results of a preceding retrospective pilot study by means of a prospective controlled investigation including a larger sample size.Therefore,the aim of this clinical investigation was to analyze the relationship between sleep bruxism and several functional and occlusal parameters.The null hypothesis of this study was that there would be no differences among sleep bruxism subjects and non-sleep bruxism controls regarding several functional and occlusal parameters.Fifty-eight sleep bruxism subjects and 31 controls participated in this study.The diagnosis sleep bruxism was based on clinical criteria of the American Academy of Sleep Medicine.Sixteen functional and occlusal parameters were recorded clinically or from dental study casts.Similar to the recently published retrospective pilot study,with a mean slide of 0.77 mm(s.d.,0.69 mm) in the sleep bruxism group and a mean slide of 0.4 mm(s.d.,0.57 mm) in the control group,the evaluation of the mean comparison between the two groups demonstrated a larger slide from centric occlusion to maximum intercuspation in sleep bruxism subjects(Mann-Whitney U-test;P50.008).However,following Bonferroni adjustment,none of the 16 occlusal and functional variables differed significantly between the sleep bruxism subjects and the non-sleep bruxism controls.The present study shows that the occlusal and functional parameters evaluated do not differ between sleep bruxism subjects and non-sleep bruxism subjects.However,as the literature reveals a possible association between bruxism and certain subgroups of temporomandibular disorders,it appears advisable to incorporate the individual adaptive capacity of the stomatognathic system into future investigations.Michelle Alicia Ommerborn Maria Giraki Christine Schneider Lars Michael Fuck Jrg Handschel Matthias Franz Wolfgang Hans-Michael Raab Ralf Schfer 2012International Journal of Oral Science2012,4,3:4

10National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales.Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser 2021Forest Ecosystems2021,8,1:2
11Bifunctional chimeric SuperCD suicide gene -YCD: YUPRT fusion is highly effective in a rat hepatoma model显示文摘AIM: To investigate the effects of catalytically superior gene-directed enzyme prodrug therapy systems on a rat hepatoma model.METHODS: To increase hepatoma cell chemosensitivity for the prodrug 5-fluorocytosine (5-FC), we generated a chimeric bifunctional SuperCD suicide gene, a fusion of the yeast cytosine deaminase (YCD) and the yeast uracil phosphoribosyltransferase (YUPRT) gene.RESULTS: In vitro stably transduced Morris rat hepatoma cells (MH) expressing the bifunctional SuperCD suicide gene (MH SuperCD) showed a clearly marked enhancement in cell killing when incubated with 5-FC as compared with MH ceils stably expressing YCD solely (MH YCD) or the cytosine deaminase gene of bacterial origin(MH BCD), respectively. In vivo, MH SuperCD tumors implanted both subcutaneously as well as orthotopically into the livers of syngeneic ACI rats demonstrated significant tumor regressions (P<0.01) under both high dose as well as low dose systemic 5-FC application,whereas MH tumors without transgene expression (MH naive) showed rapid progression. For the first time, an order of in vivo suicide gene effectiveness (SuperCD>>YCD > > BCD > > > negative control) was defi ned as a result of a directin vivo comparison of all three suicide genes.CONCLUSION: Bifunctional SuperCD suicide gene expression is highly effective in a rat hepatoma model,thereby significantly improving both the therapeutic index and the efficacy of hepatocellular carcinoma killing by fluorocytosine.Florian Graepler Marie-Luise Lemken Wolfgang A Wybranietz Ulrike Schmidt Irina Smirnow Christine D GroB Martin Spiegel Andrea Schenk Schenk Hansj(o|¨)rg Graf Ulrike A Lauer Reinhard Vonthein Michael Gregor Sorin Armeanu Michael Bitzer Ulrich M.Lauer 2005World Journal of Gastroenterology2005,11,44:2
