ABSTRACT
In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe3O4@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe3O4@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe3O4@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T2 magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe3O4@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.
ABSTRACT
Chinese traditional culture is the soil for the survival and development of traditional Chinese medi-cine,among them,the concept of A thing is valued if it is rare portal factions and master has influenced the development,communication and popularization of traditional Chinese medicine.But the spirit and thinking of harmony unity of heaven and man comparative state benevolence and self-cultivation and self-re-straint has played an active role in the development of traditional Chinese medicine.Thus this paper put forward the suggestions and opinions of strengthening the cultivation of humanistic spirit of higher traditional Chinese medi-cine talents:establishing a comprehensive evaluation standards of higher traditional Chinese medicine talents,es-tablishing scientific development concept to treat the inheritance and innovation of traditional Chinese medicine cul-ture,perfecting the curriculum provision of relevant professions,creating the conducive environment for the trans-mission of traditional Chinese medicine culture,hoping to provide a reference for the explanation of the relationship between traditional culture and traditional Chinese medicine.
