作者： jiong qiu Aoao Xu Department of Astronomy Nanjing Unversity Nanjing China

During the post_flare phase of an eruptive two_ribbon flare on February 4, 1995, the Soft X_ray Telescope (SXT) on board Yohkoh observed the rapid brightening of a set of large scale coronal loops (150-200 Mm in length). Simultaneously, coordinated ground_based observations reveal a co_incident H α surge event. To our knowledge, no H α surge event coincident with the large scale coronal brightening observed by Yohkoh has been reported. The possible mechanisms for the concurrent cool plasma ejection and the filling of the hot coronal loops are discussed. It is found that magnetic reconnection between a magnetic arcade and an overlying large scale coronal structure may account for the coincident events. Big amount of magnetic energy was converted into both mechanic energy (about 10 22 J) in the mass ejection and thermal radiation (10 23 J) contained in the large SXR loops.

AIM: To investigate the association between nutrient intakes and high incidence rate of gastric cancer among residents in Zhoushan ***: A frequency-matched design of case-control study was used during the survey on dietary factors and gastric cancer in Zhoushan Islands, China. A total of 103 cases of gastric cancer diagnosed in 2001 were included in the study and 133 controls were randomly selected from the residents in Zhoushan Islands. A food frequency questionnaire was specifically designed for the Chinese dietary pattern to collect information on dietary intake. A computerized database of the dietary and other relative information of each participant was completed. Total calories and 15 nutrients were calculated according to the food composition table and their adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by gender using unconditional logistic regression ***: High intakes of protein, saturated fat, and cholesterol were observed with the increased risk of gastric cancer particularly among males (ORQ4 vsQ1 were 10.3, 3.24, 2.76 respectively). While carbohydrate was a significant high-risk nutrient (ORQ4 vsQ1 = 14.8; Pfor linear trend = 0.024) among females. Regardless of their gender, the cases reported significantly higher daily intake of sodium mainly from salts. As to the nutrients of vitamins A and C, an inversed association with the risk of GC was found. Baseline characteristics of participants were briefly ***: The findings from this study confirm the role of diet-related exposure in the etiology of gastric cancer from the point of view of epidemiology. An increased risk of gastric cancer is associated with high intakes of protein, saturated fat, cholesterol and sodium,while consumption of polyunsaturated fat, vitamin A and ascorbic acid may have a protective effect against gastric cancer.
