It doesn't hurt to include it on your CV if you have lots of other publications there as well. As the above post said, NIW will only be considered based on your qualifications on the date of original I-140 submission, and any publications afterwards will not boost your case (although will still be useful if, after I-140 approval, the USCIS wants to see evidence that you are still publishing in your line of work before final approval of your I-485, especially if I-485 takes too long).
However, if your application is depending on this publication to boost your record, then as the above post said, it won't do you much good.
