As efex correctly pointed out, you need to include parental info to be eligible for school-based aid, though NOT for federal loans, which you're entitled to regardless. Up to you to decide whether it's worth it.
There are some (few) schools that are will to consider you independent after a certain age. Duke does this, as does Stanford.

Given their lack of income and assets, including your parents financial information would likely not affect your situation one way or the other (though you'd have to include it to be eligible for school-based aid). However, you will be required to report both your and your husband's information for medical schools, and that's where they'll get you. So to speak.
