Dark Agouti rat donor hind limbs were orthotopically transplanted into Lewis rat recipients to verify the effects of bone marrow mesenchymal stem cells on neural regeneration and functional recovery of allotransplanted limbs in the microenvironment of immunotolerance, bone marrow mesenchymal stem cells were intramuscularly （gluteus maximus） injected with FK506 （tacrolimus） daily, and were transplanted to the injured nerves. Results indicated that the allograft group not receiving therapy showed severe rejection, with transplanted limbs detaching at 10 days after transplantation with complete necrosis. The number of myelinated axons and Schwann cells in the FK506 and FK506 ＋ bone marrow mesenchymal stem cells groups were significantly increased. We observed a lesser degree of gastrocnemius muscle degeneration, and increased polymorphic fibers along with other pathological changes in the FK506 ＋ bone marrow mesenchymal stem cells group. The FK506 ＋ bone marrow mesenchymal stem cells group showed significantly better recovery than the autograft and FK506 groups. The results demonstrated that FK506 improved the immune microenvironment. FK506 combined with bone marrow mesenchymal stem cells significantly promoted sciatic nerve regeneration, and improved sensory recovery and motor function in hind limb allotransplant.

工程结构的绿色设计和绿色评价存在共性,在已建立的可持续发展工程结构全寿命周期设计理论体系基础上,参考国内外的绿色建筑评价体系,根据其共性构建了工程结构全寿命设计的绿色指标体系。该体系包含了三个指标,即以所处环境为对象的＂环境评价指标＂、以人为对象的＂用户及社会满意度指标＂和以区域和全球生态系统为对象的＂可持续发展指标＂。工程结构的全寿命设计传统指标是对现行设计方法的扩展和延伸,而绿色指标则是独立于传统设计方法体系之外的新体系,体现了全寿命设计方法的人文关怀和对自然的责任。为了将工程结构全寿命活动的环境和生态影响控制到最低水平,并使相关人群的利益最大化,通过指标分层、指标分类和权重分析,建立了建筑结构全寿命绿色设计指标体系。针对沿海高速公路桥梁结构的结构形式、用途和所处环境,构建了其全寿命设计绿色指标体系框架。
