Like the modern look and the colors of Entry 7. Love the small shadow under the boxes in 7. Like the font although would be interested in seeing lower case too. Entry 8 looks a bit too much like Microsoft logo but I like the direction you were going in that one.
I still really like 31 and 32 because they are so clean. I don't think the new ones (112, 113, 114) give the same clean look but I would still like to see a the symbol having more of a clinical message. Maybe a thin medical cross in the middle of the two squares... Or a play on the caduceus (I know before I mentioned not to use it but if it is suggestive of it, that might be ok) or a heart beat tracing. But I really like the clean look you have going...
