This is extra that I don't need "#.T-Ctq4RVPTI.twitter" the link should just be : http://bj-qr.com/a_asset_info_B395DV
It's doing the same for my Facebook shares as well.
That code is added to do our click tracking, which gives you information about the people who return to your site from shared links. If they're causing trouble you can disable them by setting the data_track_clickback option to false like this:
<script type="text/javascript">
var addthis_config = addthis_config||{};
addthis_config.data_track_clickback = false;
</script>
