Background： The aim of this study was to assess the performance of apparent diffusion coefficient （ADC） measurement obtained with diffusion-weighted magnetic resonance imaging （DW-MRI） to distinguish renal cell carcinomas （RCCs） from small benign solid renal tumors （〈4 cm）. Methods： In this cross-sectional study, 49 consecutive patients with histopathologically confirmed small solid renal tumors, and seven healthy volunteers were imaged using nonenhanced MRI and DW-MRI. The ADC map was calculated using the b values of 0, 50, 400, and 600 s/ mm2 and values compared via the Kruskal-Wallis and Mann-Whitney tests. The utility of ADC for differentiating RCCs and benign lesions was assessed using a receiver operating characteristic curve. Multiple nonenhanced MRI features were analyzed by Logistic regression. Results： The tumors consisted of 33 cases of clear-cell RCCs （ccRCCs） and 16 cases of benign tumors, including 14 cases of minimal fat angiomyolipomas and 2 cases ofoncocytomas. The ADCs showed significant differences among benign tumors （[0.90 ±0.52] x 10 x mm2/s）, ccRCCs （[1.53 ± 0.31 ] x 10 ^3 mm2/s） and the normal renal parenchyma （[2.22 ± 0.12]x 10^-3 mmVs）（P 〈 0.001）. Moreover, there was statistically significant difference between high and low-grade ccRCCs （P = 0.004）. Using a cut-offADC of 1.36± 10 3 mm2/s, DW-MRI resulted in an area under the curve （AUC）, sensitivity, and specificity equal to 0.839, 75.8%, and 87.5%, respectively. Nonenhanced MRI alone and the combination of imaging methods led to an AUC, sensitivity and specificity equal to 0.919, 93.9%, and 81.2%, 0.998, 97%, and 100%, respectively. The Logistic regression showed that the location of the center of the tumor （inside the contour of the kidney） and appearance of stiffblood vessel were significantly helpful for diagnosing ccRCCs. Conclusions： DW-MRI has potential in distinguishing ccRCCs from benign lesions in human small solid renal tumors （〈4 cm）, and in increasing the accuracy for diagnosi

目的:评估2011—2020年四川省结核病防治经费投入产生的社会效益,为制定新时期中长期发展规划提供参考依据。方法:采用回顾性研究方法,从“结核病管理信息系统”和“传染病监测”系统中收集四川省2011—2020年(“十二五”和“十三五”期间)涂阳肺结核患者治疗转归情况和肺结核患者劳动人口比例,结合四川省统计年鉴和全国结核病防治规划终期评估规划自评调查表等获取经费资料和人均国内生产总值(GDP),采用卫生经济学中常用的成本-效果、成本-效用、成本-效益等3种分析方法估算10年间结核病防治经费投入的社会效果、社会效用和社会效益,并对比分析“十二五”和“十三五”期间的估算结果。结果:2011—2020年,四川省共投入结核病防治经费76032.60万元,成功治疗涂阳肺结核患者160167例,避免了696899名健康人受到传染,挽救了1155277个伤残调整寿命年(disability adjusted life year,DALY),为社会节约医疗费用6.05亿元,挽回社会经济损失约370.32亿元。每投入1091.01元即可避免1名健康人被传染,每投入658.13元即可挽回1个DALY,每投入1元即可产生49.50元的社会经济效益。“十三五”期间带来的总社会效益(209.22亿元)较“十二五”期间(167.14亿元)增长了25.18%[(209.22-167.14)/167.14],但政府每投入1元的结核病防治经费产生的社会效益(47.56元)较“十二五”期间(52.17元)减少了4.61元。结论:2011—2020年间各级政府和国际项目对四川省结核病防控工作投入的经费产生了较好的社会效果、效用和效益。建议在保持目前经费投入力度的基础上,各级政府进一步加大投入,尤其对病原学阳性肺结核患者的发现和治疗管理力度,以期产生更高的社会效益。

Lithium-sulfur batteries have attracted attention because of their high energy ***,the "shuttle effect" caused by the dissolving of polysulfide in the electrolyte has greatly hindered the widespread commercial use of lithiumsulfur *** this paper,a novel two-dimensional TiS2/graphene heterostructure is theoretically designed as the anchoring material for lithium-sulfur batteries to suppress the shuttle *** heterostructure formed by the stacking of graphene and TiS2 monolayer is the van der Waals type,which retains the intrinsic metallic electronic structure of graphene and TiS2 *** improves the electronic conductivity of the sulfur cathode,and the transferred electrons from graphene enhance the polarity of the TiS2 *** of the polysulfide adsorption show that the TiS2/graphene hetero structure can maintain good metallic properties and the appropriate adsorption energies of 0.98-3.72 eV,which can effectively anchor *** transfer analysis suggests that further enhancement of polarity is beneficial to reduce the high proportion of van der Waals(vdW) force in the adsorption energy,thereby further enhancing the anchoring *** Li2 S decomposition barrier and Li-ion migration barrier imply that the heterostructure has the ability to catalyze fast electrochemical kinetic ***,TiS2/graphene heterostructure could be an important candidate for ideal anchoring materials of lithium-sulfur batteries.
