[Method] Three application modes （leaf application, root application and leaf/root application） of brassinosteroid for cotton under NaCI stress were de- signed to understand the effects of brassinosteroid on Na＋ and CI- accumulation, osmotic adjustment substance （proline） and biomass accumulation of cotton under NaCI stress. [Result] NaCI inhibited the growth of cotton seedlings. Compared with the control group, the biomass of cotton seedlings was decreased, Na＋ and CI- contents, MDA content and proline content were increased in cotton under NaCI stress. Under the NaCI stress, three application modes of brassinosteroid significant- ly improved the biomass, chlorophyll content in leaves, root activity and proline content; while Na~ and CI- content, MDA content were decreased. The enhancement of root activity and root physiological functions were more marked in root application and leaf/root application treatments than in leaf/root application treatment. [Conclu- sion] Three application modes of brassinosteroid all could alleviate the NaCI injuries on cotton, but root application and root/leaf application modes of brassinosteroid for cotton under NaCI stress are superior to the leaf application.展开更多

An appli- cation is proposed for IFPOC by combining the onboard hybrid aero-engine model with sequential quadratic pro- gramming （SQP）. Firstly, a steady-state hybrid aero-engine model is designed in the whole flight envelope with a dramatic enhancement of real-time capability. Secondly, the aero-engine performance seeking control including the maximum thrust mode and the minimum fuel-consumption mode is performed by SQP. Finally, digital simu- lations for cruise and accelerating flight are carried out. Results show that the proposed method improves real- time capability considerably with satisfactory effectiveness of optimization.展开更多

Methods A prospective controlled trial was conducted with 165 cases receiving pancreati- coduodenectomy in the Department of Hepatopancreatobiliary Surgery from January 2010 to May 2012. The patients were divided into Group A （end-to-end/end-to-side invaginated anastomosis, n=52）, Group B （end-to-side mucosal anastomosis, n=48）, and Group C （SPDJCS, n=65）. The preoperative data, intra- operative data, and operative outcomes （incidence of pancreatic fistula, operation time, intraoperative blood loss, peritoneal drainage, peritoneal hemorrhage, peritoneal abscess, delayed gastric emptying, pulmonary infection, postoperative infection, blood transfusion, and perioperative mortality） were com- pared among the 3 groups. Results The total incidence of pancreatic fistula was 13.9% （23/165） in all the 165 patients. The inci- dence in Group A and Group B was 23.1% （12/52） and 18.8% （9/48）, both higher than that in Group C [3.1% （2/65）, both P〈0.05]. Group C showed significantly better outcomes than group A and B in terms of the opera- tion time （5.5±1.2 hours vs. 6.1±1.1 hours, 5.5±1.2 hours vs. 6.3±1.5 hours）, volume of blood loss （412.0±205.0 mL vs. 525.0±217.0 mL, 412.0±205.0 mL vs. 514.0±217.0 mL）, and postoperative drainage amount of plasma tubes （175.0±65.0 mE vs. 275.0±80.0 mL, 175.0±65.0 mL vs. 255.0±75.0 mL） （all P〈0.05）, while Group A and Group B displayed no difference in these aspects （P〉0.05）. As complications other than pancreatic fistula were concerned, the three groups were not different from each other （P〉0.05）. Conclusions SPDJCS may have the effect of reducing the incidence of pancreatic fistula after pan- creaticoduodenectomy. It could be safe, practical and convenient technique of anastomosis for pancreaticoje- junostomy.展开更多
