We also compared the changes in the contents of serum iron, ferritin, Tf and CP in patients with (IVH) or without intraventricular hemorrhage (No-IVH), larger (≥30 ml) or smaller (<30 ml) hematoma volume, having received surgery (Surg-P) or conservative treatments (Cons-P). The gene discussed is CP; the disease is Intraventricular hemorrhage.
