title: [Application of fluorescence in situ hybridization and flow cytometry in the measurement of telomere length in Chinese patients with bone marrow failure syndrome].
abstract: OBJECTIVE
  To measure the telomere length in patients with bone marrow failure syndrome (BMF) using fluorescence in situ hybridization and flow cytometry (Flow-FISH).
  
  
  METHODS
  Blood samples were collected from 8 patients with BMF. Telomere lengths of mononuclear cells from 8 BMF patients and granulocytes from 3 of these 8 BMF patients (all these 3 patients were suffered from aplastic anemia) were measured using Flow-FISH, and the results were compared with those of normal controls. Telomere lengths were measured by Southern blot in 3 patients, and the results were compared with those obtained from Flow-FISH.
  
  
  RESULTS
  Among these 8 BMF patients, 5 have decreased telomere length in their mononuclear cells. However, different white cell subgroups, specifically mononucleated cells and granulocytes, have different degree of telomere shortening. In 3 BMF patients who underwent both Flow-FISH and Southern blot, 2 patients had consistent measurement results.
  
  
  CONCLUSIONS
  Flow-FISH can be used for the measurement of telomere length in Chinese patients with BMF.
