It was found that SOD was positively correlated with BMI, and FBG was positively correlated with course of disease and course of treatment in the SCH group (Table 3), whereas age was positively correlated with venous pH and negatively correlated with PvCO2 and SOD, education was negatively correlated with K+, and height was positively correlated with PvCO2 in the control group (Table 4). The gene discussed is SOD1; the disease is spindle cell hemangioma.
