Straw return is an effective management practice. It not only utilizes agricultural waste but also introduces dissolved organic matter(DOM) into the soil. Selenium(Se) is an essential trace element in the human diet and contributes to the popularity of Se-enriched agricultural products in the Chinese market. Moreover, there are still some Se-enriched agricultural products that have yet to be utilized. This study investigated whether Se addition in soil caused component changes in the DOM extracted from rape straw. DOM extracted from rape straw grown in soil with four Se levels(0, 0.1, 0.5 and 1.0 mg Se kg-1 soil) was characterized by UV-Visible spectroscopy, fluorescence spectroscopy and FTIR spectroscopy. The UVvisible spectra revealed that 0.1 mg Se kg-1 soil reduced the molecular weight of DOM and caused the presence of more irreplaceable aromatic structures in the substituent groups of the DOM, while 0.5 and 1.0 mg Se kg-1 soil only reduced the DOM molecular weight. Fluorescence spectroscopy indicated that Se improved the humification degree but reduced the aromaticity of DOM. FTIR spectra proved that Se altered the contents of carboxylic acids, amino acids, alcohols and aromatic heterocycles in DOM, which were maximized in the 0.5 and 1.0 mg Se kg-1 treatment groups. We concluded that Se application could change the composition of DOM extracted from rape straw, potentially impacting the nutrient bioavailability in soil. This study provides basic data on Se-enriched rape straw utilization for eco-agriculture.

Recycle Adsorption of Cu2＋ on Amine-functionalized Mesoporous Silica Monolithic

引用

Chemical Research in Chinese Universities 2013年第4期29卷 793-797页

作者： ZHAO Da-zhou JING Shu-bo xu jia-ning yang Hong ZHENG Wei SONG Tian-you ZHANG Ping State Key Laboratory of Inorganic Synthesis and Preparative Chemistry College of Chemistry Jilin University Changchun 130012 P. R. China

3-Aminopropyltriethoxysilane functionalized worm-like mesoporous silica monolithic（WMSM-NH2） was prepared and used as a new regenerable adsorbent for the removal of Cu2＋ ions. The analysis results show that the WMSM-NH2 monolithic had a high efficiency value of 99.3% for Cu2＋ remediation when the Cu2＋ solution was at an initial concentration of 10.32 mg/L. The regeneration study of the WMSM-NH2 monolithic presented that the adsorp- tion efficiency of 89.0% was remained and a mass of 92.0% was left after seven adsorption-desorption cycles were executed. The monolithic material with high resistance to the acid and good mechanical stability can facilitate the operations of adsorption and regeneration of the adsorbent.

AIM： TO investigate the safety of adult-to-adult living donor liver transplantation （A-A LDLT） in both donors and recipients. METHODS： From January 2002 to July 2006, 50 cases of A-A LDLT were performed at West China Hospital, Sichuan University, consisting of 47 cases using right lobe graft without middle hepatic vein （HHV）, and 3 cases using dual grafts （one case using two left lobe, 2 using one right lobe and one left lobe）. The most common diagnoses were hepatitis B liver cirrosis, 30 （60%） cases; and hepatocellular carcinoma, 15 （30%） cases in adult recipients. Among them, 10 cases had the model of end-stage liver disease （HELD） with a score of more than 25. Donor screening consisted of reconstruction of the hepatic blood vessels and biliary system with 3-dimension computed tomography and volumetry of whole liver and right liver volume. Various improved surgical techniques were adopted in the procedures for both donors and recipients. RESULTS： Forty-nine right lobes and 3 left lobes （2 left lobe grafts for 1 recipient, 1 left lobe graft for 1 recipient who had received right lobe graft donated by relative living donor） were obtained from 52 living donors. The 49 right lobe grafts, without HHV, weighed 400 g-850 g （media 550 g）, and the ratio of graft volume to recipient standard liver volume （GV/SLV） ranged from 31.74% to 71.68% （mean 45.35%）. All donors＇ remnant liver volume was over 35% of the whole liver volume. There was no donor mortality. With a follow- up of 2-52 mo （media 9 too）, among 50 adult recipients, complications occurred in 13 （26%） cases and 4 （8%） died postoperatively within 3 mo. Their 1-year actual survival rate was 92%.CONCLUSION： When preoperative CT volumetry shows volume of remnant liver is more than 350, the ratio of right lobe graft to recipients standard liver volume exceeding 40%, A-A LDLT using right lobe graft without MHV should be a very safe procedure for both donors and recipients, otherwise dual grafts liver transplantation

减重代谢手术减轻体重、改善代谢的长期效果已得到全球专家的广泛认可。临床已观察到减重代谢手术对肥胖相关2型糖尿病、高血压病、多囊卵巢综合征、代谢相关脂肪性肝病、远期心脑血管病等代谢紊乱的显著疗效。但现行指南推荐手术治疗2型糖尿病的BMI切点相对保守;且新的代谢手术方式如单吻合口十二指肠回肠吻合术,也展现出现极佳的减重降糖的临床效果,何种术式最适合肥胖合并2型糖尿病等代谢疾病患者仍无定论,需要更多包含中国人群的高质量临床证据加以验证并付诸临床。文章根据同济大学附属上海第十人民医院内分泌代谢中心基础及临床研究结果和文献综述,对上述减重代谢手术治肥胖相关代谢疾病的若干问题做一探讨。

Effects of Substitution of Sm for Bi in BiFeO3 Thin Films Prepared by the Sol-Gel Method

引用

Chinese Physics Letters 2010年第2期27卷 281-284页

作者：黄宁湘赵立峰许加阳陈吉利赵勇 Key Laboratory of Advanced Materials (Ministry of Education) Superconductivity R&D Center (SRDC) Southwest Jiaotong University Chengdu 610031 School of Materials Science and Engineering University of New South Wale Sydney 2052 NSW Australia

Bi1-xSmxFeO3 films with x= 0, 0.03, 0.05, 0.07 and 0.10 are prepared on LaNiO3/Si（100） substrates by the sol-gel method. X-ray diffraction patterns reveal that pure phase films with random orientations are fabricated. The results of SEM indicate that films with denser surfaces are obtained by Sm substitution. At the doping level of x=0.05, remnant polarization Pr increases to 3.19 μC/cm2 from 1.12 μC/cm2 of the un-substituted BiFeO3 film and shows enhanced ferroelectricity at room temperature. Because of the low leakage current density in the high electric field region, a polarization hysteresis loop with remanent polarization of 5.15 μC/cm2 is observed in the 0.10 Sm-substituted BiFeO3 films at the applied electric field of 226 kV/cm. Through the substitution of Sm, the leakage current density is reduced for the films with x= 0.07-0.10.

Posttraumatic stress disorder after liver transplantation

引用

Hepatobiliary & Pancreatic Diseases International 2012年第1期11卷 28-33页

作者： Shu-Guang Jin, Lu-Nan Yan, Bo Xiang, Bo Li, Tian-Fu Wen, Ji-Chun Zhao, Ming-Qing xu and jia-Ying yang Department of Pediatric Surgery and Department of Liver and Vascular Surgery , West China Hospital, Sichuan University, Chengdu 610041, China Department of Pediatrie Surgery West China Hospital Sichuan University Chengdu 610041 Chengdu China Department of Liver and Vascular Surgery West China Hospital Sichuan University Chengdu 610041 Chengdu China

BACKGROUND: Liver transplantation can lead to the development of posttraumatic stress disorder (PTSD), but the risk factors associated with this progression are not well understood. To study this syndrome in adult liver transplant recipients, a cross-sectional investigation of 296 recipients at our hospital was carried out between January and June 2010. METHODS: Study participants completed two questionnaires [a PTSD self-rating scale (PTSD-SS) and a validated Chinese version of the Medical Outcomes Study Short Form-36 (SF-36)]. Clinical and demographic data were collected from the records of the Chinese Liver Transplant Registry and via questionnaires. RESULTS: The prevalence of full PTSD and partial PTSD (that met the criteria for 2 of the 3 symptom clusters) was 3.7% and 5.4%, respectively, for all transplant recipients. Significant differences between the recipients with no PTSD, partial PTSD, and full PTSD were found in all SF-36 domains except for physical functioning (P=0.466). In general, domain scores were the highest in the recipients who did not meet the criteria for PTSD and the lowest in the recipients who met the criteria for full PTSD. Greater severity of posttraumatic stress symptoms was correlated with poorer quality of life, especially in the bodily pain (P=0.004), social functioning (P=0.001), role-emotional (P=0.048), and mental health (P<0.001) domains. The model for end-stage liver disease (MELD) scores, complications, and educational status were identified by multiple regression analysis as risk factors for developing PTSD. CONCLUSIONS: PTSD occurred after liver transplantation and was significantly associated with decreased quality of life. Higher MELD scores and complications after transplantation were risk factors that contributed to PTSD, and higher education was a protective factor.
