<qa>  How many samples were from the Tao-Yuan Psychiatric Hospital?---A Sample for Preliminary Pharmacogenetic Studies: We plan to examine a collection of DNAs in which 292 samples were from the Tao-Yuan Psychiatric Hospital and 393 samples were from the Yu-Li hospital. The samples were evaluated with the same clinical procedures and physical measurements described above. However, leptin was not measured and the HbA1C was only evaluated once. Furthermore, the rest of the biochemistries were only measured twice at the 1st month and 6th month. Nevertheless, this sample collection is worth being explored in a preliminary study.
