| 1 | Endoscopic Palliative Treatment for Malignant Obstructive Jaundice: A Report of 929 Cases显示文摘Objective:To review the experience with endoscopic palliative treatment for malignant obstructive jaundice (MOJ) in 929 patients. Methods:929 patients (598 males and 331 females) underwent 1215 endoscopic palliative drainages for MOJ in our hospital. Tumor obstruetion oeeurred in the distal common bile duet(CBD)(263 patients), the middle CBD (43),and the hilum(909).The mean bilirubin level was 284.3 μmol/L(range 26-810). Of the 1215 drainages, 599 were performed by stenting with plastic endoprosthesis, 385 by naso-biliary eatheterization, 167 by expandable metal stents,39 by combined drainage method,19 by tumor sphincterotomy and 6 by endoseopie fistulostomy. Results:The successful rate of endoscopic procedure was 94.3%. The jaundice symptom was improved in 81.8% of the patients with a significant reduetion of serum bilirubin in 64.7%. The complication after treatment occurred in 23 eases (2.6%), including eholangitis(23 eases), panereatitis (8 eases), and bleeding (one ease), and 3 eases were dead (0.2%).The median survival time of all patients was 14 months and life time analysis showed a life expectancy of 75.9%, 44.0% and 25.2% at 1, 2 and 3 years respectively. Conclusion:In the patients with MOJ seeondary to panereatobiliary malignancy, sueeessful endoscopic drainage provides adequate relief of biliary obstruetion and is associated with low morbidity and mortality. Enduseopie interventional treatment may be considered as an alternative of palliative biliary operation for the late stage of pancreatic and biliary malignaneies. | HU Bing, ZHOU Daiyun, GONG Biao, WANG Shuzhi, WU Mengchao Eastern Hepatohiliary Surgery Hospital, Second Military Medical University Shanghai 200438, China | 2002 | The Chinese-German Journal of Clinical Oncology2002，1，1： | 15 |

| 3 | Viologen-Decorated TEMPO for Neutral Aqueous Organic Redox Flow Batteries显示文摘A novel electroactive organic molecule,viz.,1-(1-oxyl-2,2,6,6-tetramethylpiperidin-4-yl)-1′-(3-(trimethylammonio)propyl)-4,4′-bipyridinium trichloride((TPABPy)Cl3),is synthesized by decorating 2,2,6,6-tetramethylpiperidin-1-oxyl(TEMPO)with viologen,which is used as the positive electrolyte in neutral aqueous redox flow battery(ARFB).Extensive characterizations are performed to investigate the composition/structure and the electrochemical behavior,revealing the favorable effect of introducing the cationic viologen group on the electroactive TEMPO.Salient findings are as follows.First,the redox potential is elevated from+0.745V for TEMPO to+0.967V for decorated TEMPO,favoring its use as the positive electrolyte.Such an elevation originates from the electron-withdrawing effect of the viologen unit,as evidenced by the nuclear magnetic resonance and single crystal structure analysis.Second,linear sweep voltammetry reveals that the diffusion coefficient is 2:97×10^(−6) cm^(2) s^(−1),and the rate constant of the one-electron transfer process is 7:50×10^(−2) cm s^(−1).The two values are sufficiently high as to ensure low concentration and kinetics polarization losses during the battery operation.Third,the permeability through anion-exchange membrane is as low as 1:80×10^(−11) cm^(2) s^(−1).It is understandable as the positive-charged viologen unit prevents the molecule from permeating through the anion exchange membrane by the Donnan effect.Fourth,the ionic nature features a decent conductivity and thus eliminates the use of additional supporting electrolyte.Finally,a flow battery is operated with 1.50M(TPABPy)Cl3 as the positive electrolyte,which affords a high energy density of 19.0WhL-1 and a stable cycling performance with capacity retention of 99.98%per cycle. | Shuzhi Hu Liwen Wang Xianzhi Yuan Zhipeng Xiang Mingbao Huang Peng Luo Yufeng Liu Zhiyong Fu Zhenxing Liang | 2021 | Energy Material Advances2021，，1： | 1 |
| 4 | Refractive Index and Extinction Coefficient of Hg_(1-x)Cd_(x)Te at 77 and 300K显示文摘We measured refractive index and extinction coefficient of n type Hg1-xCdxTe with the null ellipsometric spectrum method over the visible light region at 77 and 300K,and the dispersion relation at different temperature is discussed.The value of refractive index at 77K is smaller than that at 300K,and the changes of the extinction coefficient curve at 77K is also smaller than that at 300K. | JIANG Runqing ZHANG Shuzhi WU Feifei HU Xierong FANG Jiaxiong SHEN Jie XU Guosen | 1994 | Chinese Physics Letters1994，11，5： | 0 |
| 5 | Two Proton Interferometry in 46.7 MeV/u ^(12)C Induced Reactions显示文摘The particle-particle(P-P)correlation functions are investigated in 46.7MeV/u^(12)C induced reactions,the correlation functions are greatly enhanced at q~20 MeV/c when the sum of the energies of two correlated protons are high and almost independent on the targets.On the contrast,a strongly target dependent effect is observed for the P-P correlation functions when the sum energies are low. | XI Hongfei ZHAN Wenglong ZHU Yongtai GUO Zhongyan HU Xiaoqing LIU Guanhua ZHOU Jianqun YIN Shuzhi ZHAO Youxiong WEZhiyong FAN Enjie | 1992 | Chinese Physics Letters1992，9，8： | 0 |
