This study evaluated the efficacy of computed tomography (CT)-based three-dimensional (3D) dose-volume parameters ofthe rectum and urinary bladder as predictor for late complication in cervical cancer patients treated with radiotherapy.Forty-two patients treated with a combination of external radiotherapy and high-dose-rate intracavitary brachytherapy betweenJanuary 2002 and December 2008 were retrospectively analyzed. Brachytherapy was prescribed with standard 2D planning.Patients underwent pelvic CT at every brachytherapy. The external rectal wall and bladder wall were contoured on the CTimages, and the minimum doses delivered to 0.1 cc, 1 cc, 2 cc and 5 cc of the most irradiated rectal and bladder volumes werecalculated with dose-volume histograms. Total dose (external radiotherapy plus brachytherapy) to the rectum and the urinarybladder was transformed to the biologically equivalent dose in 2 Gy fractions with / of 3 Gy (D0.1cc, D1cc, D2cc andD5cc). The relationships between these dosimetric parameters and the incidence of late rectal complication (LRC) wereanalyzed. The values of D0.1cc, D1cc, and D2cc were significantly higher in patients with LRC than in those without (p <0.05), but the difference in the values of D5cc was not statistically significant (p = 0.092). The rate of LRC is increasedsignificantly with rectal D1cc higher than 90 GyEQD2 (p = 0.010). This study has suggested that CT-based 3D dose- volumeparameters of the rectum may be effective for predicting LRC

Electrochemical Impedance Spectroscopic Studies of the First Lithiation of Si/C Composite Electrode

采用球磨法制备了SI/C复合材料,X射线衍射(Xrd)和扫描电子显微镜(SEM)测试结果显示SI/C复合材料中硅保持着良好的晶体结构且均匀的分散于炭黑基体中.充放电测试结果表明SI/C复合材料首次放电容量高达3393 MAH/g,4周之后可逆容量均保持在1000 MAH/g左右,表现出较好的循环性能.电化学阻抗谱测试结果显示,SI/C复合材料电极在首次嵌锂过程中分别出现了代表接触阻抗、固体电解质相界面界面膜(SEI膜)阻抗、电荷传递阻抗和相变阻抗的圆弧,并详细分析了它们的变化规律.The Si/C composite materials were prepared by ball milling method,and characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM).The result displayed that Si in the Si/C com-posite materials still maintained a good crystal structure and uniformly dispersed in carbon black matrix.The first discharge capacity was 3393 mAh/g,and 4 cycles later still retained 1000 mAh/g,showing better charge-discharge cycle performance.Electrochemical impedance spectroscopy test indicated that there ap-peared three semicircles respectively representing the impedance of contact problems,solid electrolyte in-terface film(SEI film),charge transfer and phase transformation in the first lithiation,and their evolutive principles were also investigated.中央高校基本科研业务费专项资金(Nos.2010LKHX03;2010QNB04;2010QNB05);中国矿业大学科技攀登计划(No.ON090237);江苏省普通高校研究生科研创新计划(No.CX10B_153Z)资助项
