The fulllength heparanase gene is isolated. The functional heparanase is expressed within COS7 and CHO cells and few heparanse is secreted into medium. The positive CHO cells expressing active heparanase is screened, which will help explore its function and screen its antibody and antagonists from a variety of sources.

本分离出人HPA编码基因全序列；在真核细胞内成功表达出有活性的人HPA，发现此酶在COS7和CHO细胞中表达在细胞内，很少分泌到细胞外；筛选出其恒定表达细胞株，为进一步研究HPA结构功能、开发其抗体及抑制剂提供了有力的工具。

It took Cockcroft and Walton five years to build a machine that worked. Finally, in April 1932, they had a machine that produced a steady stream of hydrogen nuclei with an energy of about half a million volts. They were carefully measuring the quality of the stream, in no hurry to begin doing nuclear experiments. On the morning of April 13, Rutherford came into their room, saw what they were doing, and lost his temper. He told them to stop wasting their time and do some science. The next day, Cockcroft was occupied with other business. Walton was alone in the laboratory, ready to do the first experiment, using his hydrogen nuclei to bombard a target made of the light metal lithium. The result was spectacular. The lithium nuclei were split in two and fell apart into pairs of helium nuclei.

用了五年时间，考克饶夫和华尔顿建造出了第一台能运行的加速器，最终，在1932年，他们制造出了能够提供稳定氢粒子流的加速器，粒子能量大约为50万伏特，他们并没有急着做核试验，而是精心测量了粒子流的性质，4月13日清晨，卢瑟福来到他们的房间，看到他们还在测量，大发雷霆，告诉他们停止浪费时间，开始科学研究，第二天，考克饶夫就被安排了其他事情，只剩华尔顿一个人在实验室里，准备做第一次实验，用他的氢粒子流轰击用轻质金属锂作的标靶，结果极为壮观，锂原子被分裂成两半形成一对氦原子，氦原子释放出的能量比氢原子注入的多达三十倍！
