Objective To assess the risk factors for the occurrence of hypokalemia in patients with hepatic cancer after transcatheter arterial chemoembolizaion (TACE) therapy,and to discuss the corresponding nursing countermeasures.Methods The clinical data of 214 patients with hepatic cancer,who received TACE during the period from August 2014 to February 2015,were retrospectively analyzed.The risk factors causing hypokalemia were analyzed.Results Among the 214 patients,post-TACE hypokalemia occurred in 23 (10.7%).The main risk factors that could cause hypokalemia included anorexia,hydration,vomiting,ascites drainage,sweating.After actively symptomatic treatment,the serum potassium level returned to normal in 22 patients.One patient developed hepatic encephalopathy coma complicated by hepatorenal syndrome,the patient's family members gave up treatment and,according to family members' will the patient left hospital.Conclusion anorexia,vomiting,hydration,ascites drainage,sweating are the risk factors that can cause hypokalemia in patients with hepatic cancer after TACE therapy.The use of low potassium risk scale is helpful for the formulation of nursing countermeasures.

Aim To investigate the effects of harpagide on cerebral ischemia and the mitochondria mediated Caspase dependent apoptotic signaling pathway in mice.Methods The MCAO was employed to establish MCAO model.When the models were established, the mice were given harpagide (4, 8, 12 mg·kg-1) and edaravone (3.2 mg·kg-1) [0.1 ml·(10 g)-1] by tail vein injection after MCAO immediately.And the model and control mice were given equivalent normal saline by the same way.After MCAO for 6 h, the behavior, volume of cerebral ischemia and pathological changes in the brain were observed.Westernblot was employed to determine the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Results Compared with the model group, harpagide (4, 8, 12 mg·kg-1) could significantly decrease the increased nerve functional score, brain index, brain water content and volume of cerebral ischemia induced by cerebral ischemia.Harpagide (4, 8, 12 mg·kg-1) could reduce the contents of Cyt C in mitochondrion and pro-caspase-3 in endochylema.Conclusion Harpagide may have protective effect on the cerebral ischemia injury in mice, which might be related to the inhibition of the cerebral mitochondria mediated Caspase dependent apoptotic signaling pathway.
