The selection criteria to offer one strategy over the other as well as a stepwise patient selection for initial treatment are described. Selecting the best strategy of treatment in newly diagnosed advanced stage ovarian cancer patients is a multifactorial and multidisciplinary decision. Several factors should be taken into consideration:(1) the disease factor, related to the extension and localization of the disease as well as tumor biology;(2) the patient factor, associated with patient age, poor performance status, and co-morbidities; and(3) institutional infrastructure factor, related to the lack of prolonged operative time, an appropriate surgical armamentarium, as well as well-equipped intensive care units with well-trained personnel.展开更多

This process coincides with the late stage of China's industrialization, which international experience suggests is often frauht with twists and challenges. Among these challenges, great attention must be paid to overcapacity industrial restructuring and upgrades, and the "reindustrialization" of developed countries. As China enters the late stage of its industrialization, particularly during the 13th Five-Year Plan period from 2016 to 2020, the promotion of industrial development is of strategic significance for China to successfully complete industrialization and its economy to adapt to the "new normal ". In the face of these new challenges regarding industrial development, policymakers must strive to increase the dynamism of growth for industrial economy. In this new era, the momentum of industrial growth derives from the integration of the supply impetus of industrialization and the pull of demand caused by urbanization, while, the comprehensive deepening of refom provides the key source of momentum.展开更多

This process coincides with the late stage of China's industrialization, which international experience suggests is often frauht with twists and challenges. Among these challenges, great attention must be paid to overcapacity industrial restructuring and upgrades, and the "reindustrialization" of developed countries. As China enters the late stage of its industrialization, particularly during the 13th Five-Year Plan period from 2016 to 2020, the promotion of industrial development is of strategic significance for China to successfully complete industrialization and its economy to adapt to the "new normal ". In the face of these new challenges regarding industrial development, policymakers must strive to increase the dynamism of growth for industrial economy. In this new era, the momentum of industrial growth derives from the integration of the supply impetus of industrialization and the pull of demand caused by urbanization, while, the comprehensive deepening of refom provides the key source of momentum.
文摘Boehmeria nivea var.strigosa Zeng Y.Wu&Y.Zhao,a new variety of B.nivea(Urticaceae)from Southwest China,is here described based on evidence from morphology and molecular phylogeny.This new variety is mainly characterized by its green abaxial leaf blade,partly connate stipules,and densely patent strigose hairs on stems and potioles.The phylogenetic analysis based on rbc L,nrDNA and rbc L+nrDNA datasets,revealed that all individuals of B.nivea var.strigosa formed a monophyletic group.The conservation status of B.nivea var.strigosa is assessed as“Near Threatened”(NT)according to IUCN evaluation criteria.The discovery of this new variety is not only crucial for the taxonomy of ramie,but also provides reference for the exploration and utilization of ramie.
