Objective To investigate the expression of c-FLIPL in leukemia and explore its clinical significance. Methods The expression level of c-FLIPL mRNA in bone marrow mononuclear cells was determined by real-time polymerase chain reaction(PCR)in 103 leukemia patients with different types of leukemia,including 54 cases of acute lymphocytic leukemia(ALL)with 37 newly diagnosed,5 relapsed,and 12 complete remis-sion,38 cases of acute myeloid leukemia(AML)with 24 newly diagnosed,6 relapsed,and 8 complete remission,newly diagnosed 2 cases of acute undifferentiated leukemia(AUL),6 cases of chronic myelocytic leukemia(CML),and 3 cases of chronic myelomonocytic leukemia(CM-ML). The immunophenotype of patients were detected by flow cytometry. Results Expression level of c-FLIPL mRNA was higher in newly diag-nosed and relapsed leukemia patients. There was no significant difference between newly diagnosed and relapsed leukemia patients(P>0.05). Ex-pression level of c-FLIPL mRNA of AUL and CML was higher than that in other patients ,but there was no significant difference(P>0.05). Ex-pression level of c-FLIPL mRNA of all newly diagnosed and relapsed leukemia patients was significantly higher than that in control group and com-plete remission group(P<0.05). The expression level of c-FLIPL mRNA was correlated with risk stratification ,white blood cell(WBC),lactate dehydrogenase(LDH),hydroxybutyrate dehydrogenase(HBDH),CD45 and TEL-AML1,but was not associated with age,sex,fibrinogen and chromosome abnormality. Conclusion c-FLIPL mRNA is highly expressed in leukemia patients ,and is closely related with risk stratification , WBC,LDH,HBDH and prognosis.

Osteosarcoma ( OS) is the most common primary malignant bone tumor in children and adolescents. Currently, the combination of surgical resection and chemotherapy is the main method of treatment for OS in the clinic.Al-though, the survival rate has been greatly improved in OS patients with localized disease, the 5-year survival rate has re-mained <20%.It is very important to understand the cause of disease, to develop novel drugs or therapeutics, and to learn the disease through animal models.This review will introduce the progress of animal models of osteosarcoma over the last years.

Objective To further explore the pathogenesis of disturbed adaptive immune response in infants with sepsis. Methods Forty-eight infants with sepsis and 26 age-matched healthy infants were enrolled in this study. The HLA-DR expression of CD14~+ monocyte, the proportion of CD4~+ CD25~+ Foxp3~(high) Tr cells and the proportion of Thl7 cells were measured by flow cytometry. Cytokines (IL-1β, IL-6, TNF-α, IL-10, TGF-β and IL-17A) were measured by ELISA. Real-time PCR were used to evaluate the mRNA levels of Foxp3, ROR-γt in CD4-positive cells and IL-17A. Forty-eight infants with sepsis were divided into two groups according to HLA-DR expression of CD14~+ monocyte: DR-H group ( > 30% ) and DR-L group ( < 30% ). Results The ratio of IL-10/TNF-α in DR-L group was higher than that in healthy control or DR-H group(P <0.05). The proportion of CD4~+ CD25~+ Foxp3~(high) Tr cells and mRNA expression of transcription factor Foxp3 in DR-L group was found to be significantly higher than that in healthy control or DR-H group(P<0.05). The proportion of Thl7 cells, Serum concentration of IL-17A, the mRNA expression of IL-17A and transcription factor ROR-γt were significantly increased in DR-H group and DR-L group (P < 0.05) , while there is no significant difference between DR-H and DR-L group( P >0.05). Serum levels of Th17-inducing cytokine such as IL-1β, IL-6 were significantly elevated in DR-H group and DR-L group (P<0.05), while there is no significant difference between DR-H and DR-L group( P>0.05). Serum level of CD4~+ CD25~+ Foxp3~(high) Tr-inducing cytokine TGF-p in DR-L group was higher than that in DR-H or healthy control group(P<0. 05). Conclusion Over-activation of Th17 cells may be one of the factors causing aberrant increase of pro-inflammatory cytokine/chemotatic factor in infant with sepsis. The imbalance of CD4~+ CD25~+ Foxp3~(high) Tr cells/Th17 cells may be contributed to the pathogenic mechanism of mixed antagonist response syndrome ( MARS) in infant with sepsis. The changes of cytokine environment in infants with sepsis may be one of the factors causing the imbalance of CD4~+ CD25~+ Foxp3~(high) Tr cells/Th17 cells.
