The serum content of pepsinogen I (PGI) and serum pepsinogen II (PGII) was tested for each of the subjects using time\u2010resolved fluorescence immunoassay, which is characterised by high sensitivity and a wide measuring range.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The serum PGI and PGII levels were found to increase with age, becoming stable and similar to those of adults at the age of 16.

However, if the normal reference range for individual age groups is known, it may still serve as a useful diagnosis system as well as a detecting indicator during the course of PU treatment. There are significant differences in PGI expression in children with PU before and after PU is cured, whereas other indicators show no differences before and after treatment.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jpc.14365","type":"journal-article","created":{"date-parts":[[2019,1,19]],"date-time":"2019-01-19T19:51:17Z","timestamp":1547927477000},"page":"1103-1106","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Changes
