Methods Balb/c mice were inoculated with CVB3m(Nancy strain). The expression of lysosome cathepsin B in myocardium samples were determined by immunohistochemical staining and RT-PCR on the 3rd day, 7th day , 15th day, 30th day post-infection.

• 方法 采用免疫组织化学技术和RT-PCR技术检测Balb/c小鼠感染和未感染CVB3m(Nancy株)病毒后心肌组织中d3、d7、d15、d30溶酶体组织蛋白酶B表达。
