总结分析手术创伤导致乳糜胸的发病原因、诊断及治疗;5例病例均行剖胸探查胸导管结扎术;4例食管癌术后乳糜胸病例均经一次开胸结扎胸导管手术后治愈,1例贲门癌术后乳糜胸病例经第一次开胸结扎胸导管手术后仍复发行第二次开胸再次结扎后治愈。随访6-12个月,手术效果良好;手术创伤导致乳糜胸,首先明确诊断,同时考虑及早消除乳糜胸液,以减少身体的脂肪、蛋白质、电解质和血浆等消耗。若经反复穿刺或胸腔引流,辅以低脂肪、高蛋白、高碳水化合物饮食或完全性静脉营养方法3—4周仍然无效;或引流量大,24h超过1500ml连续5d以上者。应早日争取手术治疗。由于及时进行开胸结扎胸导管的手术治疗,乳糜胸的死亡率显著下降。  相似文献

Nurse plants are those that facilitate the growth and development of other plant species (target species) beneath their canopy because they offer benign microhabitats that are more favorable for seed germination and/or seedling recruitment than their surrounding environment. Nurse plants have been mainly used to restore vegetation in arid and sub-arid zones in recent years. Based on summarizing the definition of nurse plant and target plant, we review the nursing effect mechanisms, ecological factors that influence nursing effect, relationships between nurse plant and ecological restoration. This review also brings forward possible pairs of nurse and target species at lower subtropical areas. Furthermore, we provide the potential tendency in nurse plant research and application.  相似文献

Based on the model of grassland climate ecological productivity, the process of grassland degradation and its restoration mechanism in northern Tibetan Plateau were discussed by the model of food-chain in which the environmental and human factors were corrected. The results of case study in Nierong County showed that: ① the climate trend of becoming warmer, more droughts and gales were conflicted with the restoration of grassland degradation, even under level of perfect management the climate ecological productivity was declined from 89. 3 kg/m^2 of 1983 to 71.8 kg/m^2 of 2003; ② from 1983 to 2003, the population increased fast, while the variation of livestock on hand was little, and the cost of its maintaining is rapid grassland degradation; ③ on the present condition of overgrazing, the livestock on hand can be maintained on the level of theoretical carrying capacity in 2033 by applying the mechanism of food-chain in grassland ecological system controlled with expected coefficients, so that to realize the policy of determining the quantity of livestock according to grass growth.  相似文献

This paper concluded the vegetation restoration technique system in the arid-hot valleys and studied the anti-erosion function, environmental function and biological diversity effects of vegetation restoration on the ecosystem in the arid-hot valleys. The results showed that the soil erodibility decreased significantly after the vegetation restoration. The climate environment of the small watershed had a great improvement after the vegetation restoration, of which the temperature decreased, the humidity increased, the harsh environment of dry and hot in this region changed. The studies of the ecosystem biodiversity were mainly on the analysis of the relations between biodiversity and ecological function of the artificial ecological forest pattern and the natural enclosed treatment mode on the severely of degraded land. It could conclude that the natural enclosed treatment mode is helpful to the biodiversity of the ecosystem and the improvement and stability of the ecosystem, and Leucaena artificial forest restoration pattern reduced the species diversity but optimized the ecological function. Therefore, as to the severely and extremely severely degraded ecosystem in the arid-hot valleys, Leucaena pattern of gully control and natural enclosed treatment mode are the relatively optimal choices.  相似文献

丽娃河受损退化生态系统的近自然恢复工程及效果分析   总被引:4,自引:1,他引:3  
以丽娃河为例,针对其富营养化现状及河道特征,在传统环境工程治理基础上,构建立体植物群落和动物群落,实施近自然恢复工程,通过比较丽娃河在工程前后的水质和动植物群落的变化来验证近自然恢复工程的效果.研究表明,近自然恢复工程实施一年后,总氮和总磷分别降至0.41mg/L和0.03mg/L;叶绿素a降至7.86μg/L,水质从原来的Ⅴ类降至Ⅱ类标准(GB3838-2002),水质在很大程度上得以改善.除此之外,近自然恢复工程通过直接引入滤食藻类的底栖动物和鲢鱼鳙鱼,在调控藻类生物量的同时也在一定程度上增加了动物群落的生物多样性.实践证明,近自然恢复工程在丽娃河案例中是行之有效的,且耗资少,可以在城市生态系统近自然恢复实践中推广.  相似文献
