Abstract:

In order to study hydrogen-rich saline protects effects against liver ischemia-reperfusion injury and hepatectomy by inhibiting endoplasmic reticulum stress in miniature pig,18 3 to 4 months old and 20 to 30 kg body weight healthy miniature pigs were chosen and randomly divided into three groups:Sham group,model group and HRS group.Sham group only flipped the liver and maintained pneumoperitoneum for 3 h.Laparoscopic technique was employed to establish the model of hepatic ischemia-reperfusion combined with partial hepatectomy in model group.The surgical model was established in HRS group,and 10 mL/kg HRS was injected into the portal vein at 10 min before per-fusion and 1,2,3 d after surgery.Liver tissue samples were collected before operation,immediately after reperfusion,surgery,1 d after surgery and 3 d after surgery.HE staining and the mRNA expression of ERS-related parameters (PERK,IRE1,ATF6, GRP78,ATF4 and CHOP) in the liver were detected.The results showed that pathological changes of liver tissue in model group and HRS group were more serious than that in sham operation group,and ERS-related parameters mRNA level were increased in the model group and HRS group when compared with the sham group.In addition,the liver pathological damage in HRS group was significantly lighter than that in the model group,and all ERS-related parameters of mRNA levels were decreased in HRS group compared with the model group.Those results indicated that ischemia-reperfusion could induce liver ERS and injury,HRS could protect the liver from IRI by inhibiting ERS.

Key words: miniature pig; hydrogen-rich saline (HRS); hepatic ischemia-reperfusion; endoplasmic reticulum stress (ERS)
