care patient » care patients, safe patient, cancer patient
patient pca » patient a, patient co, patient care
among neue » among eu, among new
pca among » era among
tying up » taking up, tying _
yang jui » yang judy, yang di, yang xi
wang » wing, wan, lang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yanling ((tying up) OR (((yang jui) OR (yang (judy OR july))))) care patient pca among neue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((tying up) or (((yang jui) or (yang (judy OR july))))) care patient pca among neue ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((tying up) or (((yang jui) or (yang (judy OR july))))) care patient pca among neue ;*.
