Objective: Cervical squamous intraepithelial lesion(SIL) and cervical cancer are major threats to females' health and life in China, and we aimed to estimate the economic burden associated with their diagnosis and ***: A nationwide multicenter, cross-sectional, hospital-based survey was conducted in 26 qualified hospitals across seven administrative regions of China. We investigated females who had been pathologically diagnosed with SIL and cervical cancer, and included five disease courses(“diagnosis”, “initial treatment”,“chemoradiotherapy”, “follow-up” and “recurrence/progression/metastasis”) to estimate the total costs. The median and interquartile range(IQR) of total costs(including direct medical, direct non-medical, and indirect costs), reimbursement rate by medical insurance, and catastrophic health expenditures in every clinical stage were ***: A total of 3,471 patients in different clinical stages were analyzed, including low-grade SIL(LSIL)(n=549), high-grade SIL(HSIL)(n=803), cervical cancer stage ⅠA(n=226), ⅠB(n=610), ⅡA(n=487), ⅡB(n=282), Ⅲ(n=452) and Ⅳ(n=62). In urban areas, the estimated total costs of LSIL and HSIL were $1,637.7(IQR:$956.4-$2,669.2) and $2,467.1(IQR:$1,579.1-$3,762.3), while in rural areas the costs were $459.0(IQR:$167.7-$1,330.3) and $1,230.5(IQR:$560.6-$2,104.5), respectively. For patients with cervical cancer stage ⅠA,ⅠB, ⅡA, ⅡB, and Ⅲ-Ⅳ, the total costs were $15,034.9(IQR:$11,083.4-$21,632.4), $19,438.6(IQR:$14,060.0-$26,505.9), $22,968.8(IQR:$16,068.8-$34,615.9), $26,936.0(IQR:$18,176.6-$41,386.0) and $27,332.6(IQR:$17,538.7-$44,897.0), respectively. Medical insurance covered 43%-55% of direct medical costs for cervical cancer patients, while the coverage for SIL patients was 19%-43%. For most cervical cancer patients, the expense was catastrophic, and the extent of catastrophic health expenditure was about twice large for rural patients than that for urban patients in each ***: The e

成像技术的迅速发展使科学家和临床医生能够准确地了解癌症的发病机制和病理过程,并根据患者的情况制定个性化的治疗策略.将各种成像与治疗试剂整合为一体的癌症诊疗平台,可以同时用于癌症的诊断和治疗,受到了广泛的关注.金属-有机框架材料(MOFs)是由有机配体和金属离子/离子簇自组装而成的一种有趣而独特的多孔有机-无机杂化材料.由于其易于后修饰、孔隙和结构可设计、功能可调等特点,已被证明具有成为癌症诊疗药物负载平台的巨大潜力.本文介绍了将诊疗药物负载到MOFs中的策略,并综合评述了在磁共振成像、计算机断层扫描成像、正电子发射断层扫描成像、光学成像和光声成像等多种成像技术指导下,MOFs作为癌症诊断和治疗平台的发展概况.此外,还讨论了MOFs在癌症诊疗和临床转化方面当前面临的挑战和发展前景.

多功能混合体绘制光照模型是传统体绘制的扩展,它不仅可以绘制离散点的光照效果,而且也可以很好地绘制同质区域点的集合效果。但是,这种混合以后的光照模型不仅会在光照效果上有所减弱,而且需要调整的参数数量过大,必须通过手动调节多个参数才可以进行光照的增强。针对混合体绘制光照模型中光照减弱和调整参数过多问题,提出一种细节增强的多功能混合体绘制光照模型,在混合体绘制光照模型中引入曲率的概念,根据曲率与光照强度的对应关系对混合体绘制光照模型中的Phong光照模型进行改进,以提高绘制效果。通过几组体数据的实验结果表明,该方法不仅可以很好地提高多功能混合体绘制光照模型的细节表达,更好地辨别物体的形状特征,而且减少了手动调节参数的操作。

民国民间艺术的“重新发现”既是民间艺术本体发展的必然诉求,也是民国社会转型的重要文化现象。面对传统国民道德与现代共和政体的结构性矛盾,民间艺术被国家权力与知识阶层视为重建国民道德的本土化精神资源与理性工具,两者之间具有密不可分的话语空间。在发扬民间艺术德育传统的基础上,知识阶层对民间艺术道德启蒙功能予以现代性的理论建构,使之从个人道德修养与社会伦理关系两方面重建国民道德,既与“人性化”和“世俗化”的现代文明特征相契合,又体现出民国社会的“文明”转向。
