Methods One hundred and twelve patients with unresectable HCC were randomly divided into two groups (A and B) to receive superselective TACE. Low-dose anticancer drugs including mitomycin C (MMC) 2 ～ 8 mg,epirubicin (EPI) 5 ～ 10 mg and carboplatin (CBP) 100 mg were used in group A (n = 52),and conventional-dose of anticancer drugs (MMC 10 mg,EPI 40 mg and CBP 300 mg)for patients in group B(n = 60). Lipiodol-anticancer drugs emulsion was injected into the feeding arteries of tumor and then followed by embolization of gelatin sponge (GS) or polyvinyl alcohol (PVA) particles. Laboratory examination of the liver function including Child-Pugh scores,total bilirubin (TBIL),albumin (ALB) and alanine aminotransferase (ALT) were evaluated respectively before TACE and at third day,one week and four weeks after this procedure. Results In both groups,TBIL,ALT,and Child-Pugh scores increased (P < 0.001 or P < 0.05) and ALB decreased (P < 0.001 or P < 0.01) at three days and one week after TACE. Four weeks after-procedure,all the parameters described above showed no significant difference than those before the procedure in group A (P > 0.05). On the contrary in group B,a significant difference (P < 0.05) was found in the comparison of these parameters (except ALT). Conclusion Superselective TACE with low-dose anticancer drugs may induce transient impairment of liver function in the patients with HCC,but those patients used conventional-dose of anticancer drugs frequently cause lasting and more serious worsening of liver function.

A total of 48 male Wistar rats （4 weeks old） were randomly divided into four groups： experimental groups were orally exposed to 64.18, 128.36, 256.72 mg. kg^-1 body weight aluminum trichloride （AlCl3） in drinking water, and the control group with distilled water. The experiment lasted for 120 days. The activities of superoxide dismutase （SOD） and glutathione peroxidase （GSH-PX）, the concentration of malondialdehyde （MDA） in serum and liver, and alanine transarninase （ALT） and aspartate aminotransferase （AST） activities in serum were detected in all groups. The results showed that the activities of ALT, AST in serum and the concentrations of MDA in liver in the Al-treated groups significantly increased compared with the control group; the activities of GSH-PX and SOD in high-dose Al-treated group were significantly lower than those in control group. Our findings indicated that subchronic AI exposure could result in injures of lipid peroxidation and function in liver.展开更多
