The authors have advised the captions for Figures 4–6 on pages 3447-3449, respectively were published in the wrong order. The correct captions are as follows.
Figure 4 The effects of DXM, Ara-C and NAD+ on hair cells: (A) Positive control group (B) DXM group (C) Ara-C group (D) DXM+Ara-C group (E) NAD+ group. No significant difference was detected in OHC or IHC number among groups. Hair cells are stained with phalloidin (red).
Figure 5 The effects of DXM, Ara-C and NAD+ on stria vascularis: (A) Positive control group (B) DXM group (C) Ara-C group (D) DXM+Ara-C group (E) NAD+ group. No significant difference was observed among groups. Stria vascularis are stained with phalloidin (red) and DAPI (blue).
Figure 6 Effects of DXM, Ara-C, NAD+ on the survival of spiral ganglion neurons (SGNs): (A) Positive control group (B) DXM group (C) Ara-C group (D) DXM+Ara-C group (E) NAD+ group (F) Average of the SGN density in each cochlear region after 90 days of different groups. There was a significantly greater density of SGNs in DXM and/or Ara-C group compared to the control, but no significant difference was detected between NAD+ group and control group. SGNs are stained with a neuronal marker (NF200: green) and a nucleus marker (DAPI: blue). (**p < 0.01).
