What are some different types of insulin therapy - long acting, nph, ultra short acting?

Different insulins. Long acting insulin=nph/levemir/glargine. These help control sugars when one is not eating since the liver keeps making sugar in between meals. Ultra short acting=rapid analogs=glulisine/lispro/aspart=help control sugars that rise after meals. They are the closest we have in timing profile to natural Insulin action in non-diabetics.
