BACKGROUND: Molecular adsorbents recirculating sys- tem (MARS) liver support therapy is the development of albumin dialysis. This study was to assess the successful ap- plication of MARS artificial liver support therapy as a bridge to re-transplantation in two cases of long anhepatic duration. METHODS: MARS therapy was given after failure plasma- exchange ( PE) treatment, which resulted in circulatory de- rangement and acute renal dysfunction in a 36-year-old male patient. Finally his uncontrolled anhepatic condition led to a successful re-transplantation. In another 48-year- old man who was diagnosed as having primary nonfunction (PNF) during the liver transplantation, 10-hour MARS treatment contributed to smooth bridging of his anhepatic phase. RESULTS: The two anhepatic patients were bridged for 26 and 17 hours respectively to re-transplantation with MARS therapy. CONCLUSION: Our experience proves that MARS artifi- cial liver can be an effective support for long time bridging PNF until re-transplantation is available.

Single phase Fe 5C 2 intermetallic compound was prepared by mechanical alloying method. The phase and crystal structure of sample were analyzed with X ray differaction spectrum. The decomposing temperature of the Fe 5C 2 compound is 596.4℃ determined by the DSC curve. It is further shown that the size of nanometer crystal grain is an important condition for carrying out the solid state reaction at room temperature and normal pressure.

土壤盐渍化严重制约农业生产发展,通过提高植物耐盐性进行盐碱地综合利用,对于保障粮食安全,提升农业生产效率具有重要意义。脂质转移蛋白是一类在高等植物中广泛存在的小分子蛋白质,能够参与植株生长、信号转导以及多种生物和非生物胁迫过程。前期本课题组克隆到一个谷子中编码脂质转移蛋白的基因SiLTP1,本研究通过构建其原核表达载体和植物双元过表达载体,获得了该基因的原核表达蛋白及同源转化过表达阳性植株,经进一步筛选获得4个纯合株系。体外耐盐性试验显示, SiLTP1的原核表达蛋白具有一定耐盐性;转基因植株苗期耐盐生理指标测定显示,SiLTP1过表达植株在遭受盐胁迫时,植株体内MDA积累减少,抗氧化酶含量升高,可积累更少的过氧化氢,从而降低胁迫对植株的氧化损伤,显示基因过表达植株具有更好的耐盐性。本研究结果初步揭示, SiLTP1可正向调控谷子的耐盐性,其在谷子耐盐抗逆方面具有潜在功能,为耐盐谷子品种改良及新品种培育提供了理论基础和候选基因资源。
