Thirty-eight patients were included. The incidences of abnormal ocular VEMP (oVEMP) and cervical VEMP (cVEMP) were 65.79% and 80.26% at the time of completion of radiotherapy, and 61.84% and 71.05% at 3 months after radiotherapy. The mean and maximum radiation doses to the inner ears were both significantly associated with abnormal oVEMP and cVEMP (p < 0.05, all), but the correlations were all mild. The serum levels of IL-6 and IL-17 were both significantly associated with abnormal oVEMP and cVEMP after irradiation (p < 0.05, all).

A sequence of Til-,Al,N films has been prepared by rf reactive magnetron sputtering. The optical and electric properties versus aluminum content x have been studied. Values suitable for magneto-optic protective layers have been achieved in Til-,Al,N thin films with aluminum content x > 0.75. X-ray diffraction results show that Til-,Al,N thin films in this study are a bcc structure u p to x = 0.75, further increase in the aluminum content gives a wurtzite structure. All of the results show that the optical and electric properties of Til-,Al,N films might be related to the crystal structure.

We report on a case of Waldenström’s macroglobulinemia (WM) treated with splenic re-irradiation. To the best of our knowledge this has not been reported before. A 69-year-old Asian female patient with WM received a three-dimensional conformal radiotherapy, with 24 Gy in 12 treatment fractions in the first stage. She tolerated the treatment well, with a 37% reduction of the monoclonal immunoglobulin, an impalpable spleen, and improved hematological laboratory tests for 4 months. She was then treated with splenic re-irradiation up to 24 Gy for tumor progression. She showed no evidence of progression one year after re-irradiation, with a 55% reduction of the monoclonal immunoglobulin. Our experience demonstrates that splenic irradiation is an effective treatment to control the progression of WM.
