Purpose:The aim of the study was to examine the influence of the surgical approach for robot-assisted laparoscopic prostatectomy(RALP)on long-term urinary continence status in the era of self-reported functional status measures using the Expanded Prostate Can-cer Index Composite 26.Materials and methods:This is a prospective evaluation of 232 patients undergoing RALP between September,2019 and September,*** continence status and postoperative incontinence(pad usage)were evaluated 12 months after RALP using Expanded Prostate Cancer Index Composite 26 *** were categorized according to their surgical approach and outcome into the following groups:successful nerve sparing(NS),primarily without nerve sparing(***),and no nerve sparing by secondary resection(NNS by SR).The median levels of their questionnaire outcomes were evaluated and compared using the Wilcoxon rank sum test with continuity correction.Results:Urinary continence status 12 months after RALP differed significantly between the NS and ***(p=0.0071)and the NS and NNS by SR(p=0.0076)*** was no significant difference between the *** and NNS by SR(p=0.53)*** usage 12 months after RALP had no significant difference with regard to SR of the neurovascular bundle(p=0.14).Conclusions:Patient-reported outcomes of long-term urinary continence status seem to show no difference in postoperative conti-nence,regardless of whether a non-nerve-sparing result was planned or reached through ***,preservation of neurovascular bundle seems to lead to better long-term continence rates.

【目的】本研究利用双孢菇(Agaricus bisporus)gpdII启动子,实现了碱性真菌漆酶PIE5(CcPIE5)在灰盖鬼伞(Coprinopsis cinerea)FA2222中的同源过表达。【方法】在mKjalke液体培养基中37℃培养7 d,漆酶活力达到(24.2±1.1)U/mL。纯化的CcPIE5在pH 8.0和60℃下表现出最佳催化活性。【结果】与已经研究报道的真菌漆酶不同,CcPIE5能耐受高浓度NaCl,当NaCl浓度从0升至1.5 mol/L时,CcPIE5的k_(cat)和K_(m)均呈下降趋势,表示CcPIE5在纺织印染废水脱色中有潜在应用价值。进一步在染料废水脱色应用中,以丁香酸作为介体,CcPIE5在pH 8.5和60℃条件下可高效降解(92.9±2.3)%的靛蓝胭脂红。通过LC-MS分析确认,Isatin 5-sulfonic acid(ISA)是靛蓝胭脂红降解的主要副产物。【结论】CcPIE5在高温、碱性和含盐条件下高效脱色染料,是处理环境和工业特定应用的理想选择。

Patients without hepatocellular carcinoma progression after transarterial chemoembolization benefit from liver transplantation

引用

World Journal of Gastroenterology 2007年第5期13卷 761-767页

作者： Aiman Obed Alexander Beham Kerstin Püllmann Heinz Becker Hans J Schlitt Thomas Lorf Department of Surgery University of Regensburg Regensburg 93053Germany 不详 Department of Surgery University of Goettingen Goettingen 37073 Germany

AIM： To assess the outcome of patients, who underwent transarterial chemoembolization （TACE） for hepatocellular carcinoma （HCC） and subsequently liver transplantation （OLT） irrespective of tumor size when no tumor progression was observed. METHODS： Records, imaging studies and pathology of 84 patients with HCC were reviewed. Ten patients were not treated at all, 67 patients had TACE and 35 of them were listed for OLT. Tumor progression was monitored by ultrasound and AFP level every 6 wk. Fifteen patients showed signs of tumor progression without transplantation. The remaining 20 patients underwent OLT. Further records of 7 patients with HCC seen in histological examination after OLT were included. RESULTS： The patients after TACE without tumor progression underwent transplantation and had a median survival of 92.3 too. Patients, who did not qualify for liver transplantation or had signs of tumor progression had a median survival of 8.4 mo. The patients without treatment had a median survival of 3.8 mo. Independent of International Union Against Cancer （UICC） stages, the patients without tumor progression and subsequent OLT had longer median survival. No significant difference was seen in the OLT treated patients if they did not fulfill the Milan criteria. CONCLUSION： Selection of patients for OLT based on tumor progression results in good survival. The evaluation of HCC patients should not only be based on tumor size and number of foci but also on tumor progression and growth behavior under therapy.

Malware homology identification based on a gene perspective

引用

Frontiers of Information Technology & Electronic Engineering 2019年第6期20卷 801-815页

作者： Bing-lin ZHAO Zheng SHAN Fu-dong LIU Bo ZHAO Yi-hang CHEN Wen-jie SUN State Key Laboratory of Mathematical Engineering and Advanced Computing Zhengzhou 450001 China Georg-August-university of goettingen Goettingen 37077 Germany

Malware homology identification is important in attacking event tracing, emergency response scheme generation, and event trend prediction. Current malware homology identification methods still rely on manual analysis, which is inefficient and cannot respond quickly to the outbreak of attack events. In response to these problems, we propose a new malware homology identification method from a gene perspective. A malware gene is represented by the subgraph, which can describe the homology of malware families. We extract the key subgraph from the function dependency graph as the malware gene by selecting the key application programming interface(API) and using the community partition algorithm. Then, we encode the gene and design a frequent subgraph mining algorithm to find the common genes between malware families. Finally, we use the family genes to guide the identification of malware based on homology. We evaluate our method with a public dataset, and the experiment results show that the accuracy of malware classification reaches 97% with high efficiency.

Low-Temperature Plasticity of Naturally Deformed Calcite Rocks

Optical, cathodoluminescence and transmission electron microscope (TEM)analyses were conducted on four groups of calcite fault rocks, a cataclastic limestone, cataclasticcoarse-grained marbles from two fault zones, and a fractured mylonite. These fault rocks showsimilar microstructural characteristics and give clues to similar processes of rock *** are characterized by the structural contrast between macroscopic cataclastic (brittle) andmicroscopic mylonitic (ductile) microstructures. Intragranular deformation microstructures (*** twins, kink bands and microfractures) are well preserved in the deformed grains inclasts or in primary rocks. The matrix materials are of extremely fine grains with diffusivefeatures. Dislocation microstructures for co-existing brittle deformation and crystalline plasticitywere revealed using TEM. Tangled dislocations are often preserved at the cores of highly deformedclasts, while dislocation walls form in the transitions to the fine-grained matrix materials andfree dislocations, dislocation loops and dislocation dipoles are observed both in the deformedclasts and in the fine-grained matrix materials. Dynamic recrystallization grains from subgrainrotation recrystallization and subsequent grain boundary migration constitute the major parts of thematrix materials. Statistical measurements of densities of free dislocations, grain sizes ofsubgrains and dynamically recrystallized grains suggest an unsteady state of the rock *** and cathodoluminescence analyses prove that fluid activity is one of the major partsof faulting processes. Low-temperature plasticity, and thereby induced co-existence of macroscopicbrittle and microscopic ductile microstructures are attributed to hydrolytic weakening due to theinvolvement of fluid phases in deformation and subsequent variation of rock rheology. Duringhydrolytic weakening, fluid phases, e.g. water, enhance the rate of dislocation slip and climb, andincrea

Application of cold drawn lamellar microstructure for developing ultra-high strength wires

引用

中国有色金属学会会刊：英文版 2007年第6期17卷 1129-1138页

作者： S. Goto R. Kirchheim T . Al-Kassab C. Borchers Faculty of Engineering and Resource Science Akita University Tegata Gakuencho Akita 010-8502 Japan Institute fuer Materialphysik University of Goettingen Friedrich-Hund-Platz 1 D-37077 Goettingen Germany

Composite materials having lamellar structure are known to have a good combination of high strength and ductility. They are widely used in the fields of automobiles, civil engineering and construction, machines and many other industries. An application of lamellar microstructure for developing ultra-high strength steel wires was studied and discussed. Based on the experimental results, the relationships between the strength increase and microstructure development during the cold wire drawing were studied to reveal the strengthening mechanism. As cold drawing proceeds, the wire strength extremely increases, the microstructure changes from large single crystal lamellar structure to very fine polycrystalline lamellar one which has nano-sized grains, high dislocation density and amorphous regions. From the results obtained, it is concluded that heavy cold drawing technique is an effective method for lamellar composite to get high strength wires. Furthermore, formation process of the best microstructure for producing the ultra-high strength wires was also discussed.
