Objective To evaluate and compare the different result in hypertrophy of remained live lobe after double and single embolization. Methods Combined hepatic arterial embolization(HAE) with portal venous emboliza tion(PVE), HAE and sham operation were carried on the median and left lobes of the livers in normal and cirrhotic rats respectively. Three days later, the volume of the right lobe of the liver and its mitotic index and GPT content per gram protein were measured. Results In hormel rats, the indications mentioned increased significantly in experimen tal rats compared to control rats. The indications mentioned above also increased significantly in HAE+PVE group compared to HAE group. However, they increased more slightly in cirrhotic rats than in normal rats. Enlargement of the nonembolized part of the liver after double embolization is a result of hypertrophy, which enhanced the reserve function of the liver. Considering various degree of hypertrophy of liver cell and enhancement of reserve function, double embolization is more excellent than single embolization when the same volume liver is embolized.

Objective To study the outcomes of Lennox-Gastaut syndrome (LGS) with single-stage total corpus callosotomy combined with different resective surgeries. Methods Nine LGS patients, admitted to our hospital from May 2010 to May 2014, were chosen in our study. Their clinical data were retrospectively analyzed. According to the results of anatomy, electrophysiology and clinical comprehensive evaluation, all the 9 children received single-stage total corpus callosotomy combined with different resective operations. The differences of epileptic seizures of these children before and after surgery were compared. Results The 9 LGS children were followed up for 2 years;5 achieved Engel grade I, 3 achieved Engel grade II, and one achieved Engel grade III. The surgical effective rate was 88.9％ (8/9). The frequencies of drop seizures, convulsive seizures, tonic seizures and tonic-clonic seizures were decreased of different degrees, with drop seizures enjoying the best control. Three patients had transient silence, remarkable relief one week after surgery and total recovery half year after surgery. Conclusion Early single-stage total corpus callosotomy combined with different resective operations can help to control seizures in children with intractable LGS.
