There were no significant differences in age, M/F ratio, systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine (CR), blood urea nitrogen (BUN), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) among the cerebral infarction, cerebral hemorrhage and healthy control groups (P > 0.05), indicating that they were comparable (Table 1). The gene discussed is GPT; the disease is brain infarction.
