Since then, the suicide rate has been dropping, with much smaller increases at the end of Franklin D. Roosevelt's New Deal (1937-38), the oil crisis (1973-75) and the Double-Dip Recession (1980-82).

之后，在罗斯福新政时期（1937-38），石油危机时期（1973-75）和双底衰退时期（1980-82），自杀率开始下降。

Results Double and single suicide gene transfer were both stably expressed in GLC-82 cells. The cytotoxic effects of co-expressed TK-CD genes were superior than that of the single gene.

结果单、双自杀基因均在GLC - 82细胞中稳定表达，双基因转染组对细胞增殖的杀伤及旁杀伤效应高于单基因组。
