PROBLEM To investigate possible roles of the natural killer (NK) cell receptor killer immunoglobulin-like receptor (KIR)2DL4 expressed on uterine NK (uNK) cells during pregnancy, we investigated KIR2DL4 expression on uNK cells isolated from patients with early recurrent spontaneous abortion (RSA) and normal early pregnancy women, and functions of KIR2DL4(More)
To investigate the changes of platelet activated state and platelet activated function by trace whole blood flow cytometry (FCM), and to explore the mechanism of hemorrhage and infiltration in adults with acute leukemia, the expression percentage and changes of these expressions of CD62p and PAC-1 on platelet surface were determined by FCM of trace whole(More)
BACKGROUND Obesity has a complicated metabolic pathology, and defining the underlying mechanisms of obesity requires integrative studies with molecular end points. Real-time quantitative PCR (RT-qPCR) is a powerful tool that has been widely utilized. However, the importance of using carefully validated reference genes in RT-qPCR seems to have been(More)
OBJECTIVE To investigate the effects of anti-CD44 mAb A3D8 on the cell proliferation of human acute monocytic leukemia cell line THP-1 and its mechanism. METHODS Cell proliferation was assayed with MTT method, the expression of CD33, CD15, CD11b, CD14, Annexin-V, caspase-3 and cell cycle with flow cytometry, and the expression of p-Akt, p-ERK, bcl-2 and(More)
The aim of this study was to investigate the effect of rapamycin on cell growth and apoptosis in the myelodysplastic syndrome (MDS) cell line MUTZ-1 and possible mechanism. MUTZ-1 cells were treated with rapamycin, cell proliferation capability was determined with MTT, protein expression including Annexin V/PI, caspase 3, PTEN, p-Akt, p-mTOR and the cell(More)
OBJECTIVE To investigate the relationship between PTEN gene expression and Akt phosphorylation (p-Akt) in myelodysplastic syndrome (MDS) and to explore the progression of MDS and the mechanism of high risk transformation to acute myeloid leukemia. METHODS RT-PCR was used to detect the PTEN mRNA expression in leukemia cell lines K562 (as negative control)(More)
Herein we describe a rare fatal case of a novel bunyavirus-associated hemophagocytic lymphohistiocytosis (HLH) in a 62-year-old female patient. The novel bunyavirus infects patients with or without HLH who have similar clinical features such as fever, thrombocytopenia, and leukocytopenia. Therefore, the diagnosis of HLH can be easily missed. When HLH(More)
To evaluate the sensitivity and specificity analysis of the lineage related antibodies in acute leukemia immunophenotyping by flow cytometry (FCM), immunophenotyping in 184 patients with acute leukemia was performed by FCM analysis. The results showed that in the lineage-related antibodies of acute myelocytic leukemia (AML), the sensitivity of CD13 and CD33(More)
OBJECTIVE To investigate the expression of CD123 and its significance in lymphocytic leukemia. METHODS CD123 expression in 139 lymphocytic leukemia patients and in lymphocytes from 10 normal bone marrows (BM) was analyzed by multi-parameter flow cytometry. Cytogenetic and minimal residual disease (MRD) analysis were performed in acute B-lymphocytic(More)
