The velocity of a particle detector in granular flow can be regarded as the combination of rolling and sliding *** study of the contribution of rolling velocity and sliding velocity provides a new explanation to the relative motion between the detector and the local granular *** this study,a spherical detector using embedded inertial navigation technology is placed in the chute granular flow to study the movement of the detector relative to the granular *** is shown by particle image velocimetry(PIV)that the velocity of chute granular flow conforms to Silbert’s *** the velocity of the detector is greater than that of the granular flow around *** decomposing the velocity into sliding and rolling velocity,it is indicated that the movement of the detector relative to the granular flow is mainly caused by *** rolling detail shown by DEM simulation leads to two potential mechanisms based on the position and drive of the detector.

In normal condition, intestine mucosa possesses barrier function. When the barrier function of intestine mucosa was damaged, intestinal bacteria, endotoxin, or other substances would enter blood. It is generally accepted that biliary bacteria origins from the intestine either via duodenal papilla or intestinal mucosa. In this study, we aimed to investigate the intestinal permeability changes of cholelithiasis patients to elucidate the possible pathogenesis of cholelithiasis.

AIM: To review the application of nutrition support in patients after surgery for colorectal cancer, and to propose appropriate nutrition strategies. METHODS: A total of 202 consecutive surgical patients admitted to our hospital with a diagnosis of colon cancer or rectal cancer from January 2010 to July 2010, meeting the requirements of Nutrition Risk Screening 2002, were enrolled in our study. Laboratory tests were performed to analyze the nutrition status of each patient, and the clinical outcome variables, including postoperative complications, hospital stay, cost of hospitalization and postoperative outcome, were analyzed. RESULTS: The "non-risk" patients who did not receive postoperative nutrition support had a higher rate of postoperative complications than patients who received postoperative nutrition support (2.40 ± 1.51 vs 1.23 ± 0.60, P = 0.000), and had a longer postoperative hospital stay (23.00 ± 15.84 d vs 15.27 ± 5.89 d, P = 0.009). There was higher cost of hospitalization for patients who received preoperative total parenteral nutrition (TPN)than for patients who did not receive preoperative TPN (62 713.50 ± 5070.66 RMB Yuan vs 43178.00 ± 3596.68 RMB Yuan, P = 0.014). Applying postoperative enteral nutrition significantly shortened postoperative fasting time (5.16 ± 1.21 d vs 6.40 ± 1.84 d, P = 0.001) and postoperative hospital stay (11.92 ± 4.34 d vs 15.77 ± 6.03 d, P = 0.002). The patients who received postoperative TPN for no less than 7 d had increased serum glucose levels (7.59 ± 3.57 mmol/L vs 6.48 ± 1.32 mmol/L, P = 0.006) and cost of hospitalization (47 724.14 ± 16 945.17 Yuan vs 38 598.73 ± 8349.79 Yuan, P = 0.000). The patients who received postoperative omega-3 fatty acids had a higher rate of postoperative complications than the patients who did not (1.33 ± 0.64 vs 1.13 ± 0.49, P = 0.041). High level of serum glucose was associated with a high risk of postoperative complications of infection. CONCLUSION: Appropriate and moderate nutrition

Ⅰ型糖尿病最显著的特征是?细胞的减少缺失,因此带来一系列的并发症,越来越多的患者深受其害.?细胞作为自身免疫靶点,最终在炎性介质的诱导下被巨噬细胞和T细胞所损害.由于这种特性,临床上一般应用5类抗体即胰岛细胞抗体、胰岛素抗体、G A D65及I A-2和I A-2b来诊断及评价.除了H L A基因相关因素外,环境因素例如感染及饮食和生理心理均为该病的可疑病因.目前Ⅰ型糖尿病有多种治疗途径,临床目标定位在控制血糖,阻止?细胞的进一步损伤凋亡及控制自身免疫反应.1992年,胰岛素的发现,使得致命性的糖尿病变成慢性疾病,在一定程度上延缓了微血管并发症的进展,然而这并不能够延缓病情的进展.?细胞移植是目前唯一的一种能够合理自行调控血糖控制疾病相关并发症发展的微创手段.全胰腺移植虽然在某种程度上可以达到预期相当的效果,然而他却伴随着更高的发病率及死亡率,以及终身强制性的免疫抑制.骨髓间充质干细胞联合移植,脂多糖(lipopolysaccharides,LPS)对骨髓间充质干细胞预处理及胰岛细胞Exendin-4液体保存减轻热缺血时间损害等最新研究为胰岛细胞移植提供新的价值.
