BACKGROUND： At the time of diagnosis, most patients with gallbladder cancer are in advanced stage and the cancer is unresectable. Long-term survivors are usually seen in a small number of patients with incidental gallbladder cancer. This study aimed to identify preoperative predictors of incidental gallbladder cancer in elderly ***： A total of 4014 patients of more than 44 years old who had undergone cholecystectomy at our department from January 2000 to December 2010 were retrospectively reviewed Univariate and multivariate modalities were used to identify the predictive factors of incidental gallbladder ***： Twenty-nine of the 4014 patients who had under gone cholecystectomy for benign gallbladder diseases were histologically diagnosed as having incidental gallbladder can cer. Multivariate analysis identified that elevated carbohydrate antigen 19-9 combined with carcinoembryonic antigen and/or carbohydrate antigen 125 （P=0.045）, a gallbladder polyp greater than or equal to 1.2 cm （P=0.043） and focal gallblad der wall thickening of more than or equal to 5 mm （P=0.002）were predictive factors of incidental gallbladder ***： Cholecystectomy is suggested for patients with these predictive factors and intraoperative frozen section should be considered to rule out carcinoma.

Primary leiomyosarcoma of the inferior vena cava(IVC)is a rare disease,accounting for 0.5%of soft tissue sarcomas in adults[1].A diversity of therapeutic methods have been applied to treat this type of *** average survival time of patients who are not treated is merely 3-4 months[2].The effect of radiotherapy and chemotherapy remains unclear and controversial[3].On the other hand,the en-bloc resection with negative margins may be the only potentially curative treatment and therefore,can contribute to the long-term survival of the patients[4].During the operation,a reconstruction graft for the defected IVC needs to be chosen[5]as the graft-related complications are the surgeons’major concern,which include graft thrombosis and infection[6].Growing evidence has suggested that an allogeneic vein from donation after brain death or cardiac death is a better choice to avoid these complications[7].An allogeneic vein has been reported to be safely used in patients with pancreatic cancer in case of the portal vein and/or superior mesenteric vein invasion[8].A cryopreserved allograft can even be applied in the management of native and prosthetic aortic infections[7].Herein,we present a case of resection of a retrohepatic leiomyosarcoma of the IVC combined with partial caudate lobectomy and reconstruction with an allogeneic vein.

Budd–Chiari syndrome(BCS)is an infrequent clinical disease resulting from obstruction of the hepatic venous outflow tract anywhere from small hepatic veins to the inferior vena cava(IVC)[1].Currently,step-wise treatment strategy has been proposed and widely adopted based on the patient's status,which contains anticoagulation,thrombolysis,percutaneous recanalization,transjugular intrahepatic portosystemic shunt(TIPS)and surgical shunt[2].

BACKGROUND: Stricture formation at the bilioenteric anastomosis is a rare but important postoperative complication. However, information on this complication is lacking in the literature. In the present study, we aimed to assess its prevalence and predictive factors, and report our experience in managing bilioenteric anastomotic strictures over a ten-year period. METHODS: A total of 420 patients who had undergone bilioenteric anastomosis due to benign or malignant tumors between February 2001 and December 2011 were retrospectively reviewed. Univariate and multivariate modalities were used to identify predictive factors for anastomotic stricture occurrence. Furthermore, the treatment of anastomotic stricture was analyzed. RESULTS: Twenty-one patients (5.0%) were diagnosed with bilioenteric anastomotic stricture. There were 12 males and 9 females with a mean age of 61.6 years. The median time after operation to anastomotic stricture was 13.6 months (range, 1 month to 5 years). Multivariate analysis identified that surgeon volume (6 mm) (odds ratio: 2.871; P=0.0002) had a negative association. Balloon dilation was performed in 18 patients, biliary stenting in 6 patients, and reoperation in 4 patients. Five patients died of tumor recurrence, and one of heart disease. CONCLUSIONS: Bilioenteric anastomotic stricture is an uncommon complication that can be treated primarily by interventional procedures. Bilioenteric anastomosis may be performed by a surgeon in his earlier training period under the guidance of an experienced surgeon. Bile duct size >6 mm may play a protective role.

针对轧机普遍存在的轧辊偏心问题,结合偏心信号的特点及补偿控制方法,将一种在工业机器人重复性控制领域广泛使用的迭代学习控制方法应用在轧辊偏心补偿控制中。基于对周期误差数据不断学习,轧机偏心控制系统的压下控制调整更加精准。对构造的轧辊偏心信号进行测试,其相比于快速傅里叶变换补偿方法,迭代学习10~50次后的补偿精度提高20.1%~56.4%;经过迭代学习律参数的优化,迭代学习后补偿精度达到50%以上的同时,收敛速度大幅增加。考虑到在轧机加减速状态时偏心信号频率发生改变,通过迭代学习控制对变频信号进行补偿,经过10次的快速学习补偿,误差评价函数值达到最初的13.6%。利用冷连轧一道次的生产线实际数据进行测试,结果表明迭代学习补偿控制能够在学习过后有效提升偏心补偿精度。研究基于迭代学习控制方法,为轧辊偏心的补偿控制提供一定的参考。

Dear editor,Privacy-preserving distributed set intersection and union(PPSI, PPSU) have received much attention in recent years because of their wide applications. Most of existing solutions [1, 2] utilize secure multiparty computation protocols(SMCP) [3, 4] to settle the problem, but the SMCP methods are expensive in computation and communication. Even worse, most SMCP methods hardly continue to work if some participants disconnect.
