Two hundred and nine patients(121 male and 88 female,aged 25-69 years,mean 48.3 ± 12.5 years) with complete clinical data were recruited. We evaluated the safety of the procedure(procedurerelated death and serious complications),change of portal vein pressure before and after TIPS,symptom relief [e.g.,ascites,hydrothorax,esophageal gastricfundus variceal bleeding(EGVB)],cumulative rates of survival,and distributary channel restenosis. The characteristics of the patients surviving ≥ 5 and < 5 years were also analyzed.RESULTS: The portosystemic pressure was decreased from 29.0 ± 4.1 mm Hg before TIPS to 18.1 ± 2.9 mm Hg after TIPS(t = 69.32,P < 0.05). Portosystemic pressure was decreased and portal hypertension symptoms were ameliorated. During the 5 year followup,the total recurrence rate of resistant ascites or hydrothorax was 7.2%(15/209); 36.8%(77/209) for EGVB; and 39.2%(82/209) for hepatic encephalopathy. The cumulative rates of distributary channel restenosis at 1,2,3,4,and 5 years were 17.2%(36/209),29.7%(62/209),36.8%(77/209),45.5%(95/209) and 58.4%(122/209),respectively. No procedure-related deaths and serious complications(e.g.,abdominal bleeding,hepatic failure,and distant metastasis) occurred. Moreover,Child-Pugh score,portal vein tumor thrombosis,lesion diameter,hepatic arterio-portal fistulas,HCC diagnosed before or after TIPS,stent type,hepatic encephalopathy,and type of other interventional treatments were related to 5 year survival after comparing patient characteristics.CONCLUSION: TIPS combined with other interventional treatments seems to be safe and efficacious in patients with HCC and portal hypertension.展开更多

Modifying and designing the feeding system has become more convenient with the help of the casting software, Inte CAST. A common method of designing a feeding system is to first design the initial systems, run simulations with casting software, analyze the feedback, and then redesign. In this work, genetic, fruit fly, and interior point optimizer(IPOPT) algorithms were introduced to guide the optimal riser design for the feeding system. The results calculated by the three optimal algorithms indicate that the riser volume has a weak relationship with the modulus constraint; while it has a close relationship with the volume constraint. Based on the convergence rate, the fruit fly algorithm was obviously faster than the genetic algorithm. The optimized riser was also applied during casting, and was simulated using Inte CAST. The numerical simulation results reveal that with the same riser volume, the riser optimized by the genetic and fruit fly algorithms has a similar improvement on casting shrinkage. The IPOPT algorithm has the advantage of causing the smallest shrinkage porosities, compared to those of the genetic and fruit fly algorithms, which were almost the same.展开更多
