ABSTRACT
The aim of this study was to observe the protective effect of ademetionine 1, 4-butanedisulfonate on liver injury caused by chemotherapy in patients with leukemia. The clinical data of protective effect were analyzed retrospectively from January 2010 to April 2012. A total of 62 acute leukemia patients were divided into A group (27 cases) and B group (35 cases), the polyene phosphatidyl choline combined with ademetionine or combined with compound glycyrrhizin were given in A and B group, respectively. The changes of liver function were observed after 2 weeks, 5 patients in B group suffered from acute liver injury were treated by ademetionine as rescue therapy. Liver function was compared before and after treatment. The results showed that ALT and AST levels were significantly reduced in A group (P < 0.05), none of the patients (0/27) suffered from acute liver injury, but 14.29% (5/35) patients in B group suffered from acute liver injury, and liver function could be recovered by substitution treatment of ademetionine (the median time is 8 days, 5-14 days). It is concluded that the protective and therapeutic effect of ademetionine against liver injury caused by chemotherapy in patients with leukemia is better than that of compound glycyrrhizin.

The aim of this study was to investigate the clinical characteristics and prognosis of acute erythroleukemia (AEL, AML-M6). The clinical features and results of morphologic, immunophenotypic, cytogenetic and molecular biologic detections were retrospectively analyzed in 13 cases of AEL from 305 acute leukemia patients hospitalized between October 2007 and October 2012. The results showed that the expression of erythroid and non-erythroid cells increased at the same time. The myeloid antigens mainly expressed CD13/CD33/CD117/CD34, while the erythroid antigens expressed Gly and CD71. The karyotypic detection indicated that there were 1 case with normal karyotype, 3 cases with simple karyotypic abnormality and 2 cases with complex karyotypic abnormality, the other cases were not detected. The molecular biological detection found that the poor prognosis gene existed in 5 cases [38.5% (5/13)], including 3 cases with MLL-MLL fusion gene, 1 case with MLL mutation, and 1 cases with NRAS gene mutation, the abnormal genes were not detected in remainder 8 cases. After chemotherapy with decitabine, the complete remission (CR) rate achieved 53.5% (7/13), partial remission (DR) rate achieved 15.4% (2/13). Finally, 8 patients received allo-HSCT, the median overall survival (OS) was 20.7 months, 3 year survival rate was 79%, 3 year disease-free survival rate was 78%. It is concluded that the acute erythroleukemia is a rare subtype of AML, which is transformed from MDS and has harmful genes and poor prognosis. Allo-HSCT and treatment with decitabine may enhance the survival rate of AEL.
