Perhaps you should try some spelling variations:
done using » line using, move using
human gene » human genome, human gender, human bone
using dbs » using dcs, using ddms, using dits
dbs human » das human, des human, does human
yang jie » yang jin, yang jui, yang xi
ying jin » yang jin, jing ji
tong hui » wang hui
yan jiu » yang jin, pang jiu

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "done using dbs human gene ((yan jiu) OR (((yang di) OR (((yang jie) OR (ying jin)))))) tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: done using dbs human gene ((yan jiu) OR (((yang di) OR (((yang jie) OR (ying jin)))))) tong hui ;*.
