AIM:To compare survival between bile duct segmental resection(BDSR)and pancreaticoduodenectomy(PD) for treating distal bile duct cancers. METHODS:Retrospective analysis was conducted for 45 patients in a BDSR group and for 149 patients in a PD group. RESULTS:The T-stage(P<0.001),lymph node invasion (P=0.010)and tumor differentiation(P=0.005)were significant prognostic factors in the BDSR group.The 3-and 5-year overall survival rates for the BDSR group and PD group were 51.7%and 36.6%,respectively and 46.0%and 38.1%,respectively(P=0.099).The BDSR group and PD group did not show any significant difference in survival when this was adjusted for the TNM stage.The 3-and 5-year survival rates were: stageⅠa[BDSR(100.0%and 100.0%)vs PD(76.9% and 68.4%)(P=0.226)];stageⅠb[BDSR(55.8% and 32.6%)vs PD(59.3%and 59.3%)(P=0.942)]; stageⅡb[BDSR(19.2%and 19.2%)vs PD(31.9%and 14.2%)(P=0.669)]. CONCLUSION:BDSR can be justified as an alternative radical operation for patients with middle bile duct inselected patients with no adjacent organ invasion and resection margin is negative.

目的为了有效对抗针对彩色图像的隐写方案,提出一种新的基于RGB格式的彩色图像隐写分析方法。方法该方法中的特征包括通道内特征和通道间特征,首先从通道内差分平面上提取共生矩阵特征构成通道内特征集合,通道内特征可以有效捕捉到每一个颜色通道内差分系数之间的相关性;然后对通道与通道相互之间的二次差分平面上提取共生矩阵特征构成通道间特征集合,通道间特征可以捕捉到两两通道之间的相关性。在分类阶段利用遗传算法对多
