ABSTRACT
<p><b>OBJECTIVE</b>To prepare anticancer nanoparticles for targeting therapy for oral cancer lymph node metastasis.</p><p><b>METHODS</b>The activated carbon nanoparticles (CH-NP) were prepared for drug carrier. Pingyangmycin (PYM), a high sensitive anticancer drug for oral squamous cell carcinoma, were selected as model drug. The activated carbon nanoparticles and PYM were mixed with saline and shaken 20 minutes so that PYM was absorbed on activated carbon enough, resulting in a new formulation of PYM (PYM-CH-NP). The absorbency of PYM on activated carbon nanoparticles was evaluated.</p><p><b>RESULTS</b>The diameter distribution for CH-NP ranged form 136 nm, to 540 nm, the average diameter was 176 nm. The proportion of CH-NP to PYM was increased and more absorbency of PYM on activated carbon nanoparticles was achieved.</p><p><b>CONCLUSION</b>The activated carbon nanoparticles has high absorbency of PYM. The new formulation PYM-CH-NP can be used as targeting therapy of cervical lymph node metastasis by peri-cancer submucosal injection.</p>
