Methods: 201 type 2 diabetics, 4 idiopathic type 1 diabetics and 100 control subjects were included in the study.Two exons of IPF-1(including the coding and flanking regions) were amplified using PCR.

• 方法：选择2型糖尿病201例、特发性1型糖尿病4例及正常对照组100例作为研究对象，对IPF-1基因的两个外显子序列（包括编码区及侧翼区）进行PCR扩增，PCR产物经纯化后，经ABI 377 DNA 全自动测序仪对所有PCR产物直接测序。
