Despite the advance of diagnostic modalities, carcinoma in the body and tail of the pancreas are commonly presented at a late stage. With unresectable lesions, long-term survival is extremely rare, and surgery remains the only curative option for pancreatic cancer. An aggressive approach by applying extended distal pancreatectomy with the resection of the celiac axis may increase the resectability and analgesic effect but great care must be taken with the arterial blood supply to the liver and stomach. Sometimes, accidental injury to the pancreatoduodenal artery compromises collateral blood flow and leads to fatal complications. Therefore, knowledge of any alternative restoration of the compromised collateral flow before surgery is essential. The present case report shows a patient with a pancreatic body cancer in whom the splenic, celiac, and common hepatic arteries were involved with the tumor, which extended almost to the root of the gastroduodenal artery. We modified the procedure by reanastomosis between the proper hepatic artery and middle colic artery without vascular graft. The postoperative course was uneventful, and the patient was discharged on post-operative day 19. The patient was immediately free of epigastric and back pain.

引言长期以来,笔者注意到,自己对美学的思考方法具有某种倾向性,究竟是为什么却不太清楚。例如,对尼采关于灵感的以下论述我会无条件地赞同,以前如此,现在还是如此。——关于往昔英勇强悍时代的诗人们称之为灵感的东西,在19世纪末的今天还有谁明确知晓?倘若谁都不知道,那么就让我来叙述一下吧。——如果我有一丝一毫的迷信观念,大概不会抵御这样的想法:我不过是某种绝对威力的化身、喉舌和媒介。

Adsorption of diehtyl dithiophosphate on chalcopyrite has been studied using UV-visible spectroscopy at pH values of 4, 6, and 9. It was found that the adsorption of diethyl dithiophosphate decreased with the increasing pH treatments. The inhibition of diethyl dithiophosphate adsorption was found prominent in higher pH as a result of metal hydroxide species formation onto chalcopyrite surface. First order kinetic has been proposed and represented the adsorption mechanism. Flotation test using Hallimond tube has also been conducted and the results were consistent with the proposed mechanism. Furthermore, the morphological changes of the treated chalcopyrite were observed using Atomic Force Microscopy (AFM) showing the propensity of growth of islands, the new surfaces as products of the reaction. The hydrophobicity was measured in the form of force of adhesion. The results resembled with the approached mechanism.

为探讨煤气化反应过程中合成气CO和碳氢化合物(HCs)的产量,以及水对煤气化反应活性的影响,应用自制的CO2激光束以200℃/s的急速加热系统在CO2富集环境中(O2浓度≤10%),通过改变实验的升温速率、氧气浓度及煤样润湿度等条件,进行了煤的气化与燃烧特性实验。实验结果表明:在煤的气化与燃烧过程中,随着加热温度的升高,煤样的质量损失与合成气的产量不断增加,且煤样的质量损失与转化气体环境之间的关系为Air>富CO2>富N2;在富CO2气体环境中,随着加热温度的升高,O2浓度5%环境的CO气体和HCs气体的产量相对较大;此外发现CO气体生成量相对降低,而HCs生成量相对增加,这一结果表明煤在CO2富集气体环境的气化燃烧过程中,CO气体的生成主要依赖于O2浓度,而HCs的生成则主要依赖于H2O。

目的研究下颌逐步前伸过程中上气道形状的变化规律,了解藉改变颌位而改善通气的疗法的机制。方法对14例无鼾成年男性,使用特制口腔装置将下颌依次前伸,从初始咬合位0(F0),前伸50%(F50)、75%(F75),至前伸最大量100%(F100)。在此4个位置上行上气道磁共振扫描。测量和分析上气道各段轴截面矢向径/横向径的比值、矢向径和横向径相对于初始位置的改变百分率。结果随下颌逐步前伸,上气道轴截面矢向径/横向径的比值依次减小(P=00001),横向径变化率逐步增加(P=00023),而矢向径变化率的变化无统计学意义。结论在下颌逐步前伸过程中,上气道形状有更加横向扁圆的倾向,说明下颌前伸主要横向扩张上气道。
