| 1 | Acute upper gastrointestinal bleeding in operated stomach: Outcome of 105 cases显示文摘AIM: To compare the causes and clinical outcome of patients with acute upper gastrointestinal bleeding (AUGB) and a history of gastric surgery to those with AUGB but without a history of gastric surgery in the past.METHODS: The causes and clinical outcome were compared between 105 patients with AUGB and a history of gastric surgery, and 608 patients with AUGB but without a history of gastric surgery.RESULTS: Patients who underwent gastric surgery in the past were older (mean age: 68.1±11.7 years vs 62.8±17.8 years, P= 0.001), and the most common cause of bleeding was marginal ulcer in 63 patients (60%). No identifiable source of bleeding could be found in 22 patients (20.9%) compared to 42/608 (6.9%) in patients without a history of gastric surgery (P = 0.003). Endoscopic hemostasis was permanently successful in 26 out of 35 patients (74.3%) with peptic ulcers and active bleeding or non-bleeding visible vessel. Nine patients (8.6%) were operated due to continuing or recurrent bleeding,compared to 23/608 (3.8%) in the group of patients without gastric surgery in the past (P= 0.028). Especially in peptic ulcer bleeding patients, emergency surgery was more common in the group of patients with gastric surgery in the past [9/73 (12.3%) vs 19/360 (5.3%), P = 0.025].Moreover surgically treated patients in the past required more blood transfusion (3.3±4.0 vs 1.5±1.7, P = 0.0001) and longer hospitalization time (8.6±4.0 vs 6.9±4.9 d,P = 0.001) than patients without a history of gastric surgery. Mortality was not different between the two groups [4/105 (3.8%) vs 19/608 (3.1%)].CONCLUSION: Upper gastrointestinal bleeding seems to be more severe in surgically treated patients than in non-operated patients. | Vassiliki N Nikolopoulou Konstantinos C Thomopoulos George I Theocharis Vassiliki A Arvaniti Constantine E Vagianos | 2005 | World Journal of Gastroenterology2005，11，29： | 9 |
| 2 | Effects of Thermomagnetic Treatment on Microstructure and Mechanical Properties of Rolling Bearing Steel显示文摘The influence of the thermomagnetic treatment on metallurgical and mechanical properties of the rolling bearing steel was investigated.The heating and/or cooling and tempering processes of the samples occurred in a magnetic field having certain strengths.The X-ray diffraction (XRD) patterns of the rolling bearing (RUL 1) steel samples exhibited a beneficial effect of the magnetic field on the structure,phase transformation,and tension state.An increased fatigue reliability was found for the rolling tribomodel made from thermomagnetically treated steel. | Constantin Gheorghies Ioan I Stefanescu | 2010 | Journal of Iron and Steel Research(International)2010，17，9： | 4 |
