This study, from the perspective of environmental ethics, duly proposed the brand-new concept of 'appropriate garden of primitive ecology', proceeded from the orientation, form, value, theoretical basis, realistic significance, culture and consumption psychology of 'garden of primitive ecology', fully developed outstanding ecological wisdoms and morals in traditional Chinese garden culture, boosted garden designs to the environmental ethics level of eco-justice, to seek for the approach to 'garden of primitive ecology' with indigenous Chinese environmental ethic characteristics.展开更多

Multiple data sources, including socioeconomic interviews with 302 households, focus group discussions, and informal interviews with pastoralists were used to capture various aspects of drought and drought adaptation and coping practices.Standardized precipitation index derived from long-term rainfall data obtained from the Kenya Meteorological Service was used to quantify different degrees of drought intensity between 1950 and 2012. Results revealed that extreme drought events were increasingly frequent, and have impacted negatively on pastoral livelihoods. In order to adapt to or cope with climatic anomalies, households are using a variety of strategies. In addition to the traditional short-term coping mechanisms, the long-term adaptation strategies used include diversification of livelihood sources; livestock mobility to track forage and water resources;diversification of herd composition to benefit from the varied drought and disease tolerance, as well as fecundity of diverse livestock species; and sending children to school for formal education as a long term investment expected to pay back through income from employment. Policies anddevelopment interventions that reduce risks, diminish livelihood constraints, and expand opportunities for increased household resilience to drought are critical complements to the existing pastoral strategies.展开更多

Methods: From January 2006 to October 2010, 27 anastomosed arteries in 27 replanted digits were included in the study. The patients included nine males and four females. The patients received DSA at 48 to 96 h after digital replantation. Based on DSA image, the blood flow was classified into normal, slow-running, and flow-stopping types. The patients with normal digital blood flow were given continuous routine treatments; the patients with slow-running flow were given the conservative treatments, such as release of the tight dressings, removal of stitches, keeping warm, the use of massage, and the use of anticoagulants and anti-inflammatory drugs; the patients with flow-stopping received immediate surgical re-exploration. Results: In this series, 23 digits in 11 patients showed a normal blood flow, and these digits all survived. In one of 13 patients, two digits which displayed slow-running flow also survived after conservative treatments. In two of 13 patients, two digits showed flow stopping, with one surviving and one failing after re-exploration and arterial revision. Conclusions: The DSA can be used to assess the blood flow of the proper digital artery in the early stage after replantation. It provides essential information for salvaging the replanted finger.展开更多
