[Expression of Kindlins and angiopoietins in acute myeloid leukemia].

This study was purposed to explore the expression of Ang-1, Ang-2, Tie-2, Kindlin-2, Kindlin-3 in different leukemia cell lines and bone marrow of acute myeloid leukemia (AML) patients and its clinical significance. The levels of Ang-1, Ang-2, Tie-2, Kindlin-2, Kindlin-3 in bone marrow of AML patients and nontumorous control group as well as leukemia cell lines (K562, KG-1a, U937, HL-60 and Jurkat) were detected by RQ-PCR. The difference of positive rate and expression level between AML patients and controls was analyzed.

[Dynamic monitoring of minimal residual disease in acute lymphoid leukemia].

The aim of this study was to establish a method for quantitative detection of immunoglobulin heavy chain (IgH) gene rearrangements and to explore its clinical application in monitoring minimal residual disease (MRD) of acute lymphoid leukemia (ALL). Clonal IgH gene rearrangements in 51 patients with ALL at diagnosis were identified by multiplex PCR assay. PCR products were sequenced and pairwise in IMGT data base.
