AIM： TO evaluate quality of life （QOL） following Ivor Lewis, left transthoracic, and combined thoracoscopic/ laparoscopic esophagectomy in patients with esopha- geal cancer. METHODS： Ninety patients with esophageal cancer were assigned to Ivor Lewis （/7 = 30）, combined thora- coscopic/laparoscopic （n = 30）, and left transthoracic （n = 30） esophagectomy groups. The QOL-core 30 questionnaire and the supplemental QOL-esophageal module 18 questionnaire for patients with esophageal cancer, both developed by the European Organization for Research and Treatment of Cancer, were used to evaluate patients＇ QOL from 1 wk before to 24 wk after surgery. RESULTS： A total of 324 questionnaires were collect- ed from 90 patients, 36 postoperative questionnaires were not completed because patients could not be contacted for follow-up visits. QOL declined markedly in all patients at 1 wk postoperatively： preoperative and 1-wk postoperative global QOL scores in the Ivor Lewis, combined thoracoscopic/laparoscopic, and left transthoracic groups were 80.8 ± 9.3 vs 32.0 ± 16.1 （P 〈 0.001）, 81.1±9.0 vs 53.3 ± 11.5 （P 〈 0.001）, and 83.6 ± 11.2 vs 46.4 ± 11.3 （P 〈 0.001）, respectively. Thereafter, QOL recovered gradually in all patients. Patients who underwent Ivor Lewis esophagectomy showed the most pronounced decline in QOL; global scores were lower in this group than in the combined thoracoscopic/laparoscopic （P 〈 0.001） and left trans- thoracic （P 〈 0.001） groups at 1 wk postoperatively and was not restored to the preoperative level at 24 wk postoperatively. QOL declined least in patients under- going combined thoracoscopic/laparoscopic esopha- gectomy, and most indices had recovered to preopera- tive levels at 24 wk postoperatively. In the Ivor Lewis and combined thoracoscopic/laparoscopic groups, pain and physical function scores were 78.9 ± 18.5 vs 57.8 ± 19.9 （P 〈 0.001） and 59.3 ± 16.1 vs 70.2 ± 19.2 （P = 0.02）, respectively, at 1 wk postoperatively and 26.1 ± 28.6 vs 9.5 ± 15.6 （P =

Quantifying biochemical variables of corn by hyperspectral reflectance at leaf scale

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2008年第5期9卷 378-384页

作者： Qiu-xiang YI Jing-feng HUANG Fu-min WANG Xiu-zhen WANG Institute of Remote Sensing and lnformation Technology Zhejiang University Hangzhou 310029 China Institute of Zhejiang Meteorology Hangzhou 310004 China

To further develop the methods to remotely sense the biochemical content of plant canopies,we report the results of an experiment to estimate the concentrations of three biochemical variables of corn,i.e.,nitrogen(N),crude fat(EE) and crude fiber(CF) concentrations,by spectral reflectance and the first derivative reflectance at fresh leaf scale. The correlations between spectral reflectance and the first derivative transformation and three biochemical variables were analyzed,and a set of estimation models were established using curve-fitting analyses. Coefficient of determination(R2),root mean square error(RMSE) and relative error of prediction(REP) of estimation models were calculated for the model quality evaluations,and the possible opti-mum estimation models of three biochemical variables were proposed,with R2 being 0.891,0.698 and 0.480 for the estimation models of N,EE and CF concentrations,respectively. The results also indicate that using the first derivative reflectance was better than using raw spectral reflectance for all three biochemical variables estimation,and that the first derivative reflectances at 759 nm,1954 nm and 2370 nm were most suitable to develop the estimation models of N,EE and CF concentrations,respectively. In addition,the high correlation coefficients of the theoretical and the measured biochemical parameters were obtained,especially for nitrogen(r=0.948).

Adsorption of Iminodiacetic Acid Resin for Lutetium

引用

Journal of Rare Earths 2004年第5期22卷 640-643页

作者：熊春华姚彩萍王惠君 College of Food Science Biotechnology and Environmental Engineering Zhejiang Gongshang University Hangzhou 310035 China College of Marine Science and Technology Zhejiang Ocean University zhoushan zhejiang 310004 China

The adsorption behavior and mechanism of a novel chelate resin, iminodiacetic acid resin (IDAAR) for Lu(Ⅲ) were investigated. The statically saturated adsorption capacity is 210.8 mg·g^(-1) at 298 K in HAc-NaAc medium. The Lu(Ⅲ) adsorbed on IDAAR can be eluted by 0.5 mol·L^(-1) HCl and the elution percentage reaches 96.5%. The resin can be regenerated and reused without obvious decrease in adsorption capacity. The apparent adsorption rate constant is k_(298)=2.0×10^(-5) s^(-1). The adsorption behavior of IDAAR for Lu(Ⅲ) obeys the Freundlich isotherm. The thermodynamic adsorption parameters, enthalpy change ΔH, free energy change ΔG and entropy change ΔS of IDAAR for Lu(Ⅲ) are 13.1 kJ·mol^(-1), -1.37 kJ·mol^(-1) and 48.4 J·mol^(-1)·K^(-1), respectively. The apparent activation energy is E_a=31.3 kJ·mol^(-1). The molar coordination ratio of the functional group of IDAAR to Lu(Ⅲ) is about 3∶1. The adsorption mechanism of IDAAR for Lu(Ⅲ) was examined by chemical method and IR spectrometry.
