BACKGROUND: Pancreatic adenocarcinoma remains the fourth leading cause of cancer-related death and is one of the most aggressive human tumors. At present, surgical resection is the only potentially curative treatment. Early neck division is inadequate when invasion of the superior mesenteric artery (SMA) is suspected or in cases of replaced or accessory right hepatic artery. Malignant periampullary tumors often invade retroperitoneal peripancreatic tissues and a positive resection margin is associated with a poor long-term survival. DATA SOURCES: English-language medical databases, PubMed, ELSEVIER and SPRINGERLINK, were searched for articles on 'posterior approach pancreaticoduodenectomy', 'superior mesenteric artery first approach', 'retroperitoneal tissue', 'hanging maneuver', and related topics. RESULTS: The modification allowed the surgeon to early identify the nonresectability of a replaced right hepatic artery if present, enabling complete dissection of the right side of the SMA and portal vein as well as complete excision of the retroportal pancreatic lamina. CONCLUSION: Pancreaticoduodenectomy with early retropancreatic dissection is a useful and safe technical variant, which is indicated for the improvement of the safety and curative effect of the procedure.

The single-electron tunneling processes in optically excited coupled quantum dots can be divided into two parts:the electron and the hole parts,which are analytically obtained in the framework of the Keldysh *** tunneling process is selective tunneling,which results in dark tunneling *** tunneling currents are co-determined by the resonance energies and probability distributions of the particular quantum channels defined by the electron-hole complex resonant states.

BACKGROUND: Since the widespread adoption of laparoscopic cholecystectomy (LC) in the late 1980s, a rise in common bile duct (CBD) injury has been reported. We analyzed the factors contributing to a record of zero CBD injuries in 10 000 consecutive LCs. METHODS: The retrospective investigation included 10 000 patients who underwent LC from July 1992 to June 2007. LC was performed by 4 teams of surgeons. The chief main surgeon of each team has had over 10 years of experience in hepatobiliary surgery. Calot's triangle was carefully dissected, and the relationship of the cystic duct to the CBD and common hepatic duct was clearly identified. A clip was applied to the cystic duct at the neck of the gallbladder and the duct was incised with scissors proximal to the clip. The cystic artery was dissected by the same method. Then, the gallbladder was dissected from its liver bed. A drain was routinely left at the gallbladder bed for 1-2 days postoperatively. RESULTS: No CBD injuries occurred in 10 000 consecutive LCs, and there were 16 duct leaks (0.16%). Among these there were 10 Luschka duct leaks (0.1%) and 6 cystic duct leaks (0.06%). Four hundred thirty cases were converted to open cholecystectomy (OC), giving a conversion rate of 4.3%. After a mean follow-up of 17.5 months (range 6-24 months), no postoperative death due to LC occurred, and good results were observed in 95% of the patients. CONCLUSIONS: In our 10 000 LCs with zero CBD injuries, the techniques used and practices at our department have been successful. Surgeon's expertise in biliary surgery, preoperative imaging, precise operative procedures, and conversion from LC to OC when needed are important measures to prevent CBD injuries.

儒家"以教化政"思想跨越知识、伦理道德和政治等领域,目的在将政治道德化,但知识和道德的评价标准往往掌握在权势者手中;传统政治伦理在很大程度上依靠的是家族-宗法伦理,这种情况难以完全摆脱宗法伦理的深刻影响,因而也就难以彻底克服其限制性;在当今多元价值并存的时代,传统伦理作为传统价值系统不能不同时被当做既定的事实,为了政治上平等、文明的要求不能不在政治伦理上做出对宗法或泛宗法伦理的限制性要求,政治服从文明发展程度所决定的伦理,才有社会长久的稳定与和谐。

在批评前人天人观缺失的基础上,荀悦基于其独特的"三术"和"三势"说阐释历史过程中的主体性原则,总结汉代儒家伦理实践的新认识,提出了贯穿于"天命"和"人事"、"天道"和"人道"、"性命"和"人情"诸范畴的天人互动关系论,以形成其儒家伦理的哲学基础,不仅提供了理解儒家伦理的新视角,而且奠定了后儒的致思路径与生活内容。

儒学的根本在工夫。《学》《庸》工夫论从主张修身之必要到一切人皆以修身为本的变化,说明工夫既是道德也是政治伦理的内容。诚之既包括主体对善的自觉,也包括明善之后诚身的实践;诚意虽内在地包含着慎独和毋自欺,但它还不仅包括传统儒家理解的意向的真切不妄,而且包括往往被忽略的意识的真实可靠。中庸之道和大学之道虽各有自己的结构和内容,而它们本质上仍是以近道为工夫论的基本特点。三纲领八条目作为无穷尽的工夫过程是"近道"思想的根据。近道思想是儒者自我反思和自我批判的表现。

局部复发是进展期胃癌行D2治愈性切除后预后不良的主要原因。我们发现，在胃癌胃系膜中存在着一类新的转移．其与原发灶、淋巴结或血管不相连接．而胃系膜被同有筋膜完整地包绕着。表面部分被脏层腹膜所覆盖，这类转移（第五转移）有可能是胃癌术后局部复发的重要原凶。因此，我们建议在行D2手术时，除了进行彻底的原发灶切除和系统的淋巴结清扫外，还应该增加第三根治原则，即完整的胃系膜切除，以免第五转移散落在手术野．遭致局部复发。
