| 1 | 煤灰沉积的传热过程模型及其数值研究显示文摘计算流体力学(CFD)方法的应用在锅炉设计或燃烧设备的改造过程中有着十分重要的作用.本文研究了实际燃烧过程中普遍存在的煤灰沉积现象对数值计算结果的影响,提出了描述煤灰沉积的新型传热模型,比较了新模型采用前后数值计算结果与实测数据的差异,从而验证了该模型的合理性,提高了对炉内积灰、结渣过程数值描述的精度. | 徐明厚 郑楚光 HE X G AZEVEDO J L T CARVALHO M G | 2002 | 工程热物理学报2002，23，1： | 10 |
| 2 | Therapeutic and prophylactic thalidomide in TNBS-induced colitis: Synergistic effects on TNF-α, IL-12 and VEGF production显示文摘AIM: To evaluated the therapeutic and prophylactic effect of thalidomide on 2, 4, 6-trinitrobenzene sulfonic acid (TNBS)-induced colitis. Thalidomide has been reported to downregulate the expression of tumor necrosis factor a (TNF-α), IL-12, and vascular endothelial growth factor (VEGF), hallmarks of intestinal inflammation in Crohn's disease (CD). METHODS: Male Wistar rats were divided in five groups of ten animals each. Four groups received a rectal infusion of TNBS in ethanol. The first group was sacrificed 7 d after colitis induction. The second and third groups received either thalidomide or placebo by gavage and were sacrificed at 14 d. The fourth group received thalidomide 6 h before TNBS administration, and was sacrificed 7 d after induction. The fifth group acted as the control group and colitis was not induced. Histological inflammatory scores of the colon were performed and lamina propria CD4+ T cells, macrophages, and VEGF+ cells were detected by immunohistochemistry. TNF-a and IL-12 were quantified in the supernatant of organ cultures by ELISA. RESULTS: Significant reduction in the inflammatory score and in the percentage of VEGF+ cells was observed in the group treated with thalidomide compared with animals not treated with thalidomide. Both TNF-αand IL-12 levels were significantly reduced among TNBS induced colitis animals treated with thalidomide compared with animals that did not receive thalidomide. TNF-αlevels were also significantly reduced among the animals receiving thalidomide prophylaxis compared with untreated animals with TNBS-induced colitis. Intestinal levels of TNF-αand IL-12 were significantly correlated with the inflammatory score and the number of VEGF+ cells. CONCLUSION: Thalidomide significantly attenuates TNBS-induced colitis by inhibiting the intestinal production of TNF-α, IL-12, and VEGF. This effect may support the use of thalidomide as an alternate approach in selected patients with CD. | Ana Teresa Carvalho Heitor Souza Antonio Jose Carneiro Morgana Castelo-Branco Kalil Madi Alberto Schanaider Flavia Silva Fernando Antonio Pereira Júnior Márcia G Pereira Cláudio Tortori Ilana Dines Jane Carvalho Eduardo Rocha Celeste Elia | 2007 | World Journal of Gastroenterology2007，13，15： | 6 |
