Excel is a poor choice when doing more than basic analysis. If you Google "doing statistical analysis in excel" you will find plenty of examples demonstrating major discrepancies between Excel and a real statistical package.
Your best option would be to ask a biostatistician in your department to help you with your choice of test and software.

Hi Jiang,
If your data is not complicated, you could do the t-test in Excel. Google
"excel two-tailed t-test" and you'll get a lot of hits. Many statistics
tests are already built in Excel, whereas other are not hard to be done as
long as you understand how their equations work and have some basic
knowledge in Excel's built-in functions.
