| 1 | Bleeding Dieulafoy's-like lesions of the gut identified by capsule endoscopy显示文摘Dieulafoy's-like lesions (DLs-like) represent a cause of obscure gastrointestinal bleeding, enteroscopy being the main diagnostic and therapeutic procedure. Frequently, more than one enteroscopy is needed to identify the bleeding vessel. In our practice, video capsule endoscopy (VCE) identified and guided therapy in four cases of DLs-like; three of them were localized on the small bowel. We report, for the first time, a diagnosis of colonic DL-like performed by colon capsule endoscopy. Two patients presented with severe cardiovascular disorders, being hemodynamically unstable during VCE examination. Based on the VCE findings, only one invasive therapeutic procedure per patient was necessary to achieve hemostasis. VCE and enteroscopy may be regarded as complementary procedures in patients with gut DLs-like. | Lidia Ciobanu Oliviu Pascu Brindusa Diaconu Daniela Matei Cristina Pojoga Marcel Tantu | 2013 | World Journal of Gastroenterology2013，19，29： | 8 |
| 2 | Effects of soil warming history on the performances of congeneric temperate and boreal herbaceous plant species and their associations with soil biota显示文摘Aims Climate warming raises the probability of range expansions of warm-adapted temperate species into areas currently dominated by cold-adapted boreal species.Warming-induced plant range expansions could partly depend on how warming modifies relationships with soil biota that promote plant growth,such as by mineralizing nutri-ents.Here,we grew two pairs of congeneric herbaceous plants spe-cies together in soil with a 5-year warming history(ambient,+1.7℃,+3.4℃)and related their performances to plant-beneficial soil biota.Methods Each plant pair belonged to either the mid-latitude temperate climate or the higher latitude southern boreal climate.Warmed soils were extracted from a chamberless heating experiment at two field sites in the temperate-boreal ecotone of North America.To isolate poten-tial effects of different soil warming histories,air temperature for the greenhouse experiment was identical across soils.We hypothesized that soil with a 5-year warming history in the field would enhance the performance of temperate plant species more than boreal plant species and expected improved plant performances to have positive associations with plant growth-promoting soil biota(microbial-feeding nematodes and arbuscular mycorrhizal fungi).Important Findings Our main hypothesis was partly confirmed as only one temperate spe-cies performed better in soil with warming history than in soil with his-tory of ambient temperature.Further,this effect was restricted to the site with higher soil water content in the growing season of the sampling year(prior to soil collection).One of the boreal species performed con-sistently worse in previously warmed soil,whereas the other species showed neutral responses to soil warming history.We found a positive correlation between the density of microbial-feeding nematodes and the performance of one of the temperate species in previously wetter soils,but this correlation was negative at the site with previously drier soil.We found no significant correlations between the performance of the other temperate species as well as the two boreal species and any of the studied soil biota.Our results indicate that soil warming can modify the relation between certain plant species and microbial-feeding nematodes in given soil edaphic conditions,which might be important for plant performance in the temperate-boreal ecotone. | Madhav P.Thakur Peter B.Reich Cameron Wagg Nicholas A.Fisichelli Marcel Ciobanu Sarah E.Hobbie Roy L.Rich Artur Stefanski Nico Eisenhauer | 2017 | Journal of Plant Ecology2017，10，4： | 0 |
| 3 | Prognostic factors of response to endoscopic treatment in painful chronic pancreatitis显示文摘AIM To evaluate the endoscopic treatment efficacy and prognostic factors of long-term response to treatment for painful chronic pancreatitis.METHODS This retrospective analysis identified 168 patients with painful chronic pancreatitis hospitalized during January 2010-January 2015 in a Romanian tertiary referral center. Data on demographics, medical history, alcohol consumption, smoking habit, clinical parameters, type and number of endoscopic procedures and hospital admissions number were collected from the medical charts and analyzed. The absence or substantial reduction of pain(mild pain) at the end of the follow-up associated with the technical success of endotherapy was considered as clinical success. RESULTS Among the 168 patients with painful chronic pancreatitis admitted to our department during the study period, 39(23.21%) had optimal response to the medical therapy. One hundred and twenty-nine patients required endoscopic treatment. The median follow-up period was 15 mo(range, 0-60 mo). Overall, technical success of endotherapy was achieved in 105 patients(81.39%). More than two-thirds of patients(82.78%) had substantial improvement of pain after the endoscopic treatment, including frequency and severity of the pain attacks. Patients younger than 40 years had significantly more successful endoscopic procedures(P = 0.041). Clinical success was higher in non-smoking patients(P = 0.003). The hospital admission rate was higher in patients with recognized alcohol consumption(P = 0.03) and in smokers(P = 0.027). The number and location of pancreatic stones and locations of strictures did not significantly influence the technical success(P > 0.05) or the clinical success(P > 0.05).CONCLUSION Younger age than 40 years can be considered an important factor positively influencing endoscopic treatment outcome in patients with painful chronic pancreatitis. | Alina Tantau Alina Mandrutiu Daniel-Corneliu Leucuta Lidia Ciobanu Marcel Tantau | 2017 | World Journal of Gastroenterology2017，23，37： | 0 |
