Nineteen patients had a family history of CF. The median age at diagnosis was 8.7 years. Among Chinese CF patients, 70.8% had bronchiectasis, 9.7% had a hemoptysis history, 33.6% had clubbed fingers, 17.7% had allergic bronchopulmonary aspergillosis, and 29.2% had chronic diarrhea; the incidence of malnutrition was 52.2%. Five patients had jaundice, 26 patients had hepatomegaly, and 9 patients had meconium ileus in the neonatal period, and the incidence of liver cirrhosis was 5.3%. The predominant organism in airways was <jats:italic>Pseudomonas aeruginosa<\/jats:italic>, followed by <jats:italic>Staphylococcus aureus<\/jats:italic>. Seventy\u2010nine patients underwent the sweat test, and all of them were positive, with an average chloride ion level of 122.2\u2009mmol\/L. Eighty\u2010eight Chinese CF patients underwent genetic testing, and 74 CF transmembrane conductance regulator (CFTR) gene mutations were reported. The most common gene mutation was c.2909G\u2192A.
