Have your image open. Now go to 'Filter > Noise > Reduce Noise'.
Match your 'reduce noise' setting's to mine. Then press OK.
Now go to 'Image > Adjustments > Brightness/Contrast'.
This part is more trial and error. Try setting the setting's to mine but if you feel the image looks too bright or has to much contrast applied then lower/increase the settings depending on your preference, then press OK.
Now go to 'Filter > Sharpen > Sharpen'..
Here's my result.
