Hmm imo the only thing you can do with that is try and clone the top.
Cut it about 10cm long, trim the bottom fan leaves off, and then clip the top ones so the leaf area is smaller. Do not remove them just clip the ends of the leaves.
Get some cloning gel or powder and stick in rock wool if you got it. Some seedling soil would prob work.
Put under a low wattage bulb for 18/6 - 24/0 hours and anywhere in between.
Roots would take anywhere from 4 to 14 days. Possibly more.
I would also add you should do a bit of basic reading up on growing rather than just posting and taking one persons advice. There is an excellent FAQ which can be found at the top of all RUI pages, i think. (top right corner next to tools). Check it out.
