This study also tested the oxidative stress and inflammatory responses and found that DIPC and RIPC both significantly increased the antioxidant enzyme SOD and decreased inflammatory factors TNF-α and IL-1β 24 hours after surgery, further confirming that ischemic preconditioning could protect liver function through preventing the progression of oxidative stress and inflammatory responses in ischemia reperfusion injury. The gene discussed is TNF; the disease is ischemia.
