AIM： To compare the effect of percutaneous transhepatic portal vein embolization （PTPE） and unilateral portal vein ligation （PVL） on hepatic hemodynamics and right hepatic lobe （RHL） atrophy.METHODS： Between March 2005 and March 2009, 13 cases were selected for PTPE （n = 9） and PVL （n = 4） in the RHL. The PTPE group included hilar bile duct carcinoma （n = 2）, intrahepatic cholangiocarcinoma （n = 2）, hepatocellular carcinoma （n = 2） and liver metastasis （n = 3）. The PVL group included hepatocellular carcinoma （n = 2） and liver metastasis （n = 2）. In addition, observation of postoperative hepatic hemodynamics obtained from computed tomography and Doppler ultrasonography was compared between the two groups.RESULTS： Mean ages in the two groups were 58.9 ± 2.9 years （PVL group） vs 69.7 ±3.2 years （PTPE group）, which was a significant difference （P = 0.0002）. Among the indicators of liver function, including serum albumin, serum bilirubin, aspartate aminotransferase, alanine aminotransferase, platelets and indocyanine green retention rate at 15 min, no significant differ- ences were observed between the two groups. Preop-erative RHL volumes in the PTPE and PVL groups were estimated to be 804.9 ±181.1 mL and 813.3 4±129.7 mL, respectively, with volume rates of 68.9% ± 2.8% and 69.2% ±4.2%, respectively. There were no significant differences in RHL volumes （P = 0.83） and RHL volume rates （P = 0.94）, respectively. At 1 mo after PTPE or PVL, postoperative RHL volumes in the PTPE and PVL groups were estimated to be 638.4±153.6 mL and 749.8 ± 121.9 mL, respectively, with no significant difference （P = 0.14）. Postoperative RHL volume rates in the PTPE and PVL groups were estimated to be 54.6% ± 4.2% and 63.7% ± 3.9%, respectively, which was a significant difference （P = 0.0056）. At 1 mo after the operation, the liver volume atrophy rate was 14.3% ± 2.3% in the PTPE group and 5.4%± 1.6% in the PVL group, which was a significant difference （P = 0.0061）.CONCLUSION： PTPE is a

A water-soluble polyhydroxylated fullerene, i.e., a fullerenol, with 44 hydroxyl groups and 8 secondary bound water molecules, C60（OH）44·8H2O （estimated average structure）, has been synthesized in a facile one step reaction from pristine C60 by hydroxylation with hydrogen peroxide in the presence of a phase-transfer catalyst, tetra-n-butylammonium hydroxide （TBAH）, under organic/aqueous bilayer conditions. The fullerenol exhibited high water solubility, up to 64.9 mg/mL, under neutral （pH = 7） conditions. Dynamic light-scattering （DES） analysis showed a narrow particle size distribution, of 1-2 nm, indicating that the fullerenol had high dispersion properties in water. The results of particle size analyses, which botll focused on a single nanoregion and were conducted using a novel induced grating （IG） method and a scanning probe microscope （SPM）, were consistent with the DES results. A plausible reaction mechanism, which includes fullerene oxide intermediates detected by liquid chromatography-mass spectrometry （LC-MS）, has been proposed.

Complex hydride materials have been widely investigated as potential solid electrolytes because they have good compatibility with the lithium metal anodes used in all-solid-state batteries. However, the development of all-solid-state batteries utilizing complex hydrides has been difficult as these cells tend to have short cycle lives. This study investigated the capacity fading mechanism of all-solid-state lithium–sulfur(Li–S) batteries using Li4(BH4)3I solid electrolytes by analyzing the cathode microstructure. Crosssectional scanning electron microscopy observations after 100 discharge–charge cycles revealed crack formation in the Li4(BH4)3I electrolyte and an increased cathode thickness. Raman spectroscopy indicated that decomposition of the Li4(BH4)3I solid electrolyte occurred at a constant rate during the cycling *** combat these effects, the cycle life of Li–S batteries was improved by increasing the amount of solid electrolyte in the cathode.
