Abstract:

目的:探讨成人骶前肿瘤的手术入路及技巧。方法:回顾性分析2009年至2011年之间诊治的10例成人骶前肿瘤患者资料,并结合文献分析。结果:10例肿瘤均获完整切除,5例经骶尾部切除,4例经腹入路切除,1例经腹膜外入路切除。无围手术期死亡,无排便异常、大出血等并发症。经随访2~4年,术后仅1例粘液性脂肪肉瘤患者局部复发。结论:对骶3平面以下、直肠指捡可触及肿瘤1半以上者可经骶尾部切除,位置较高、肿瘤较大者宜行经腹入路。术前准备及术中手术技巧对于获得满意的手术效果具有重要意义。

To explore surgical approaches and skills about adult anterior sacral tumor. Methods: 10 adult sacral tumor patients during 2009-2011 had been retrospectively analyzed, combined with literature study. Results: All of the cases accepted complete resection, 5 by sacrococcygeal approach, 4 by transabdominal approach, 1 by extra-peritoneal approach. There is no complication like perioperative mortality or abnormal defecation and bleeding. Only one mucinous liposarcoma recurrence has been detected during a 2 - 4 years follow up. Conclusion: tumors below 3th sacral plane especially more than half of which could be reached by digital rectal examination are suitable for the sacrococcygeal approach. Those higher and larger are adapting the abdominal approach. Preoperational preparation and operative skills are also of great importance to obtain satisfactory therapeutic result.

Abstract:
大连理工大学每年有大量的公示材料,涉及到职称评审、升职考核、竞聘材料等等,有些公示材料只能查看不允许下载,或者需要对公示材料设置查看和下载的权限。设计与实现符合大连理工大学需要的校内公示系统,既要保证教师公示材料的安全可靠,同时又要满足公示材料全校范围内的分享阅读。校内公示系统基于FlexPaper技术设计实现方案,将office文件等转换成pdf文件,再将pdf文件转换为swf文件,在校内门户页面使用FlexPaper插件播放公示文件,该技术方案成熟可靠并被广泛使用。系统架构设计采用业界领先的基于领域驱动的开发方式,分为表现层、系统应用层、应用支撑层、数据资源层及基础平台层,业务逻辑集中在领域层,系统采用我校统一的信息安全体系和标准规范,使系统具有高可用性、高可靠性及高性能。
Every year, Dalian University of Technology produces a huge amount of publicity material related to human resource management work, such as the professional title evaluation, promotion evaluation, competitive selection etc. Some of these publicity documents are restricted to read only, and no downloading is allowed, or different reading/downloading permissions are set to different documents. Considering designing a document sharing system corresponded with the actual needs of the university, it is important to guarantee both the security and the school-wide sharing me-chanism of the publicity documents. Document Sharing System is based on the FlexPaper technical proposal. After converting Microsoft office files to pdf files, swf tools can be used to change pdf files to swf files, then these documents can be loaded on the university portal website using FlexPaper plugin which is reliable and widely used by many companies. The system architecture, based on the industry-leading Domain Driven Design approach, is divided into presentation layer, system appli-cation layer, application support layer, data source layer and basic platform layer. Business logic is concentrated in the domain layer and the cluster-based load balancing and cache make the system with high availability, high reliability and high performance.

Abstract:
随着我校发展战略的实施和推进,不断扩大人才引进和人才交流,适时推出周转教师公寓较好的解决了教师的后顾之忧,但供需矛盾很突出,给管理带来了很大的困难。无论是校内教师、短期交流人才,还是管理部门,均迫切需要建立适合于我校的教师公寓管理系统。通过建设基于数字化校园的功能齐全的教师公寓管理系统,简化了教师的办事流程,公开透明租房规则和结果,避免教师与管理部门的矛盾,减轻管理部门的工作量,提高公寓的利用率和教师的满意度。
With the incessant implementation and promotion of our university’s development strategy, talent introduction and personnel exchanges are expanding. A timely introduction of temporary teacher-apartments becomes the way to liberate teachers from accommodation worries. However, the contradiction between supply and demand is very prominent that puts more stress on man-agement. Whether the school teachers, short-term exchange personnel or administrative depart-ments are in urgent need of establishing a teacher’s apartment management system which is suit-able for our university. An all-round teachers apartment management system can helps to simplify teachers’ service procedure, open and transparentize the apartment renting rules and results, avoid conflicts between teachers and administrative departments, reduce the management work-load and can improve the utilization rate of apartment and teachers’ satisfaction degree.

Abstract: 为了探讨添加植酸酶后家禽日粮中植酸含量与营养物质代谢的关系,选用爱拔益加成年公鸡24只,随机分为6组,每组4个重复,设计日粮的植酸含量分别为0,4,6,8,10和12g/kg,以日粮中未添加植酸酶作为对照组,研究日粮中添加植酸酶(处理组)对磷平均真消化率、粗蛋白(cp)和赖氨酸表观消化率及表观代谢能的影响。结果表明,日粮的植酸含量为4,6,8,10,12g/kg时,处理组与对照组相比,磷(p)的平均真消化率分别提高了3.03%,10.12%(p<0.05),16.90%(p<0.05),37.71%(p<0.05)和28.14%(p<0.05);表观代谢能(ame)分别提高了0.018,0.078,0.191,0.309和0.217mj/kg;粗蛋白(cp)表观消化率分别提高了0.24%,2.26%,3.60%,4.00%和1.85%;赖氨酸(lys)表观消化率分别提高了1.01%,1.70%,3.05%,4.82%和1.89%。磷真消化率、ame、cp和lys表观消化率分别与日粮的植酸含量呈负线性关系。由试验结果可知当日粮植酸含量为10g/kg时,营养物质利用率提高幅度最大。

Abstract:
目的: 研究肛管减压对于预防直肠癌前切除术后吻合口瘘的作用。方法: 纳入20101月至20126月期间在华西医院胃肠外科中心同一手术组行直肠癌前切除术的患者,收集其基本人口学资料、肿瘤相关临床指标、合并症、肿瘤距肛缘距离、是否安置肛管、是否发生吻合口瘘等资料。使用SPSS17.0软件进行统计分析。结果: 共纳入患者432人,其中肛管减压组207人,对照组225人。两组基线水平无差别。肛管减压组吻合口瘘的发生率为1.45% (3/207),低于对照组4.89% (11/225),差异有统计学意义(P = 0.044)。行logistic回归分析显示糖尿病、BMI > 25 kg/m2、肿瘤下缘距肛门<7 cm为直肠癌前切除术后吻合口瘘的独立危险因素(P < 0.001, = 0.001, 0.002)结论:

Abstract:

目的:本研究通过测量不同T、N分期直肠癌患者直肠系膜的平均CT衰减值,以寻求直肠癌CT术前T、N分期新的参考指征。方法:纳入2010年9月至2012年9月在四川大学华西医院胃肠外科行手术治疗的直肠中下段腺癌病人123例,术前均采用64排MSCT行全腹部及盆部增强扫描。在每例患者的CT上选取3个癌肿平面,每个平面的直肠系膜上选取6个椭圆形ROI测量CT衰减值,并计算出直肠系膜的平均CT衰减值,然后将不同T、N分期的直肠系膜平均CT衰减值进行相关分析及对比。结果:直肠系膜的平均CT衰减值与直肠癌T分期正相关(rs = 0.439,P < 0.001),但是除T4期高于T1-3期并有统计学意义外(P均 < 0.05),T1、T2、T3期两两间的差异没有统计学意义(P均 > 0.05);直肠系膜的平均CT衰减值与N分期没有相关关系(rs = 0.030, P = 0.740),N0、N1、N2期两两间的差异没有统计学意义(P均 > 0.05)。结论:直肠系膜CT衰减值可为鉴别中下段直肠癌是否侵出直肠系膜提供重要的辅助指标。 

To find a new method for preoperative CT staging in rectal cancer by measuring the mean CT value of mesorectum in patients with different T, N stages. Methods: 123 patients who were diagnosed with middle or lower rectal adenocarcinoma and accepted surgery during September 2010 to September 2012 in Department of Gastrointestinal Surgery, West China Hospital, Sichuan University were enrolled. Contrast-enhanced 64-slice spiral CT examination of the abdomen and pelvis was performed before operation. In every patient, 3 planes of tumor were selected on CT. On each plane, 6 elliptical ROIs were selected within the mesorectum and the CT value of each ROI was measured. Then the mean CT value of mesorectum was calculated. The correlation analysis between the mean CT value and T, N stage was conducted and the mean CT value of mesorectum of different T, N stages was compared. Results: The mean CT value of mesorectum and the T stage of rectal cancer were positively correlated (rs = 0.439, P < 0.001). The mean CT value of T4 was significantly higher than T1-3(all P < 0.05), but there was no statistical difference between each pair of T1, T2 and T3 (all P > 0.05). There was no statistical correlation between the mean CT value and N stage of rectal cancer (rs = 0.030, P = 0.740). The mean CT value of mesorectum had no statistically difference between each pair of N0, N1, N2 (all P > 0.05). Conclusion: The CT value of mesorectum can be a useful index to help identify whether the tumor has invaded out of the mesorectum or not in the middle and lower rectal cancer.

Abstract: A novel method was proposed for the simultaneous separation and determination of six food additives, benzoic acid, sorbic acid, saccharin sodium, acesulfame potassium, ponceau 4R and allura red AC, by high performance liquid chromatography (HPLC). After optimized the separation conditions of HPLC, the separation can be completed within 18 min by using a ZORBAX Eclipse Plus C18 column (150 mm×4.6 mm, 5 μm) with 20 mmol/L ammonium acetate (pH 6.9) and methanol as the mobile phases. The gradient elution was performed by 8% methanol (0~2 min), 8%~50% methanol (2~3 min), 50% methanol (3~9 min), 50%~8% methanol (9~12 min) and 8% methanol (12~18 min). The detection wavelength was set at 235 nm. This method has been successfully applied to the analysis of meat products and the average recoveries ranged from 80.7% to 94.4% at high and low spiked levels. The relative standard deviations (RSDs, n=3) were between 2.0% and 7.1%. The method is simple, rapid, accurate and suitable for the simultaneous determination of the six food additives in meat products.
