AIM To benchmar. sever.ty of complications using the Accor.ion Sever.ty Gr.ding System(ASGS) in patients under.oing oper.tion for.sever. pancr.atic injur.es. METhODS A pr.spective institutional database of 461 patients with pancr.atic injur.es tr.ated fr.m 1990 to 2015 was r.viewed. One hundr.d and thir.y patients with AAST gr.de 3, 4 or.5 pancr.atic injur.es under.ent r.section(pancr.atoduodenectomy, n = 20, distal pancr.atectomy, n = 110), including 30 who had an initial damage contr.llapar.tomy(DCL) and later.definitive sur.er.. AAST injur. gr.des, type of pancr.atic r.section, need for.DCL and incidence and ASGS sever.ty of complications wer. assessed. Uni-and multivar.ate logistic r.gr.ssion analysis was applied. r.SULTS Over.ll 238 complications occur.ed in 95(73%) patients of which 73% wer. ASGS gr.des 3-6. Nineteen patients(14.6%) died. Patients mor. likely to have complications after.pancr.atic r.section wer. older. had a r.vised tr.uma scor.(r.S) r. shocked on admission, had gr.de 5 injur.es of the head and neck of the pancr.as with associated vascular.and duodenal injur.es, r.quir.d a DCL, r.ceived a lar.er.blood tr.nsfusion, had a pancr.atoduodenectomy(PD) and r.peat lapar.tomies. Applying univar.ate logistic r.gr.ssion analysis, mechanism of injur., r.S hock on admission, DCL, incr.asing AAST gr.de and type of pancr.atic r.section wer. significant var.ables for.complications. Multivar.ate logistic r.gr.ssion analysis however.showed that only age and type of pancr.atic r.section(PD) wer. significant. CONCLUSION This ASGS-based study benchmar.4}d postoper.tive mor.idity after.pancr.atic r.section for.tr.uma.

Chinese Jour.al of Aer.nautics 2019年第9期32卷 2037-2046页

The coaxial compound helicopter.has two possible str.tegies for.heading contr.l: collective differ.ntial and r.dder.deflection. A flight dynamics model is developed to assess the effect of differ.nt heading contr.l str.tegies. This includes the tr.m char.cter.stics, steady flight per.or.ance,contr.llability, and manoeuvr.bility. The tr.m study demonstr.tes that heading contr.l str.tegies ar. less influential on tr.m r.sults, and the steady flight per.or.ance is also not significantly affected by the heading contr.l str.tegy adopted. The contr.llability analysis shows although heading bandwidth and phase delay r.sults at var.ous speeds with differ.nt heading contr.l str.tegies ar. all satisfied, the contr.l der.vative of the collective differ.ntial decr.ases as speed incr.ases, and its heading aggr.ssive agility is degr.ded into Level 3 in high-speed flight. In addition, using collective differ.ntial would lead to sever. heading-r.lling coupling as for.ar. speed incr.ases. On the contr.r., the contr.l der.vative and aggr.ssive agility of the r.dder.deflection is impr.ved with for.ar. speed, and ther. is no evidence of heading-r.lling coupling. Finally, the tr.nsient tur. MissionTask-Element(MTE) is utilized to investigate the heading manoeuvr. char.cter.stics in differ.nt heading contr.l str.tegies, which indicates that the collective differ.ntial would add the amplitude of contr.l input and the power.consumption dur.ng this MTE.
