Moreover, our study indicated that after intervention, the Hb, ALB, and PA levels in the OG were higher than those in the CG, and the IgA, IgG, and IgM levels in the OG were higher than those in the CG, suggesting that early enteral nutrition combined with fine nursing could promote the nutritional status and immune function of patients with intracranial aneurysms undergoing minimally invasive surgery, which was similar to previous reports (28, 29). The gene discussed is GSTM1; the disease is Dilatation of the cerebral artery.
