Hello Yan,

The approach I would take to this problem is to first create a "Custom Track" 
of your regions of interest, and then intersect existing annotation tracks with 
that Custom Track.  

Here is some information on custom tracks,
http://genome.ucsc.edu/cgi-bin/hgCustom
http://genome.ucsc.edu/goldenPath/help/customTrack.html

Or if you'd like to download data and write your own scripts to search through 
it, here is our downloads page for hg18 (sometimes takes awhile to load):
http://hgdownload.cse.ucsc.edu/goldenPath/hg18/database/

Please note that the Galaxy website has some kind intersection tools as well:
http://main.g2.bx.psu.edu/

I hope some of these tools will be useful to you.  Please don't hesitate to 
contact us again if you require further assistance.
