Gold nanoparticles ( AuNPs) have been widely used in biomedicine due to their unique physical and chemical properties as well as good biocompatibility. Current research in this field has been focused on AuNP radiosensitization in radiotherapy for cancer. Extensive studies in vivo and in vitro have showed the radiosensitization effect of AuNPs. However, the mechanism of radiosensitization by AuNPs still requires further studies. Right now, the radiation?insensitive phase ( G0+G1 phase) to radiation?sensitive phase ( G2+M phase ) transition of tumor cells by AuNPs is widely considered as the main cause of radiosensitization. There are many influencing factors for AuNP radiosensitization such as particle size, surface modification, microscopic distribution, radiation energy, radiation dose, and type of tumor cells. Moreover, safety should also be taken into account in AuNP radiosensitization. Clinical trials of AuNPs have been carried out right now. More studies on AuNP radiosensitization are needed to achieve real clinical transformation.

Objective To evaluate the effect of small-dose Lorazepam on residual dizziness in elderly patients with benign paroxysmal positional vertigo (BPPV) after successful particle repositioning maneuver (PRM).Methods A total of 268 patients aged 60 years and over, who were diagnosed as BPPV and underwent successful treatment of PRM, were randomly assigned to medication group and control group.The patients in the medication group were prescribed low-dose lorazepam for 1 week (0.25 mg/time, 3 times/d), whereas the patients in the control group were not prescribed any medication.Hamilton Anxiety Scale (HAMA) was employed to evaluate the anxiety status of patients before and after PRM, and the effect of small-dose lorazepam on residual dizziness was accessed by using the Dizziness Handicap Inventory (DHI) scale and the Activities-specific Balance Confidence (ABC) scale in elderly BPPV patients after PRM.Results No difference in HAMA scores was found between the two groups (t=-0.316, P=0.753) before PRM.The medication group (t=19.931, P=0.000) and the control group (t=26.930, P=0.000) showed a significant improvement in HAMA scores after PRM versus before PRM.However, HAMA scores after PRM was lower in the medication group than in the control group (t=14.967, P=0.000).The medication group had significant improvements after PRM versus before PRM in the following: DHI scores (t=43.661, P=0.000), functional (t=32.326, P=0.000981), emotional (t=31.981, P=0.000), physical (t=14.330, P=0.000) subscale scores, as well as in the ABC scores (t=-23.248, P=0.000).The improvements were also found in the control group in DHI scores (t=46.282, P=0.000), functional (t=32.117, P=0.000), emotional (t=34.563, P=0.000),physical (t=13.182, P=0.000) subscale scores, as well as in the ABC scores(t=-24.536, P=0.000)after PRM versus before PRM.However, after PRM the total DHI score, functional,emotional and physical subscale scores were lower in medication group than in control group (t=5.994, 3.206, 4.757 and 2.851, respectively, P=0.009, 0.002, 0.000 and 0.005).The ABC scores were higher in medication group than in control group (t=2.678, P=0.008) after PRM.Conclusions The elderly patients with BPPV are often accompanied by symptoms of anxiety.The small-dose Lorazepam can alleviate residual dizziness in elderly BPPV patients after successful PRM.
