Objective: To assess the prevalence of folate, vitamin B12, and iron deficiencies and their associations with anemia among women of childbearing age in northern China, an area with a reported high incidence of neural tube defects. Methods: Plasma folate, vitamin B12, ferritin, and hemoglobin levels were measured among 1,671 non-pregnant women of childbearing age from Xianghe County, Hebei Province, China in June 2004. Results: Geometric means [95 % confidence interval (CI)] of plasma concentrations were 9.3 (4.0, 21.6) nmol/L for folate, 213.1 (82.4, 550.9) pmol/L for vitamin B12, 17.4 (1.1, 278.6) µg/L for ferritin, and 129.9 (104.6, 161.4) g/L for hemoglobin (Hb). Approximately 24 % of women had biochemical evidence of folate deficiency (<6.8 nmol/L), 21.4 % were deficient (<148 pmol/L) in vitamin B12, 30.2 % had iron depletion (<15 μg/L), and anemia (Hb < 120 g/L) was detected among 15.4 % of women. Of the three nutrients, only iron depletion (ferritin < 15 μg/L) was independently associated with anemia (adjusted odds ratio = 6.4, 95 % CI 4.8, 8.6). Conclusions: Although there were substantial proportions of folate and vitamin B12deficiencies among women of childbearing age in northern China, iron deficiency was the most important contributor to anemia.
English AbstractMagic Flute is Mozart¡¦s last work of opera, and also the peak of Singspiel. This opera integrates the composing styles of German, French, and Italian operas and demonstrates the roundedness and refinement characteristic of Mozart¡¦s later works. The original libretto of Magic Flute, written by Schikaneder, has a lot to share with the ideology of Freemasonry. Therefore, besides the entertaining effects common in Singspiel , this opera is ethically instructive.Papageno is the comic character in Magic Flute and the soul of it, too. He functions to carry on the plot and takes on the task of amusing the audience. His performance, including the musical essence, the singing skills, and the action, holds the key to the success of the opera.This research is divided into seven sections:1. Mozart¡¦s life and his creation of operas2. The creation process of Magic Flute3. Introduction to the roles in Magic Flute4. The characteristics of the role of Papageno5. Discussion about the singing of Papageno6. Some suggestions about the action of Papageno7. Conclusion
