Background and Objective Pseudohypertrophic muscular dystrophy is a kind of lethal X-chain recessive inherited disease. The etiological factor is mainly due to gene mutation of Xp21 which induce the structural and functional abnormality of a kind of cell skeleton protein: dystrophin.

背景和目的假肥大型肌营养不良症(pseudohypertrophic muscular dystrophy，PMD)是一种常见的致死性X-连锁隐性遗传病，病因主要是由于X染色体短臂2区1带(Xp21)的基因突变而导致一种细胞骨架蛋白——抗肌萎缩蛋白的结构和功能异常所致。

The two groups were compared for outcomes, including death, retransplant, nonfatal major adverse cardiac event, cardiac function, morbidity, and development of confirmed allograft vasculopathy.

The enzyme activity of cotton bollworm was indicated; after 144 hours teated with the subthal dose (LC50) of the pesticiedes, the difference was detected in the GSTs activities when compared with contrast.

酶动力学研究表明：用4种药剂的亚致死浓度LC50剂量处理棉铃虫3龄幼虫，在药剂处理后的144h内，幼虫GSTs活性发育变化规律与对照有一定的差异。

The effects of the dynamic electron beam irradiation on insects as Sitophilas Oryzae Linnaeus, Rhizopertha dominica Fabricius and Tribolium Herbst hidden in stored bulk wheat and the quality of irradiated wheat were investigated.

利用电子束动态辐照的方法对我国南方主要储粮害虫米象、谷蠹、赤拟谷盗等的辐照感应性及致死剂量进行了研究，同时对辐照后小麦的品质进行了分析。

Results Human complement can be activated by unsensitized EL-4 cell through the first pathway.

结果 未致敏EL-4细胞可直接以Ca2+、Mg2+离子依赖的第一途径活化人血清补体系统，在细胞数为1×104～2×104时，1：200稀释的人血清补体为EL-4细胞的非致死剂量。

In clean diluent condition, the median lethal concentration (MLC50) of CIO2 against bacteria and yeast was 9.4 and 8.4 ppm, respectively.
