BACKGROUND Live attenuated hepatitis A vaccine (H2 strain) is widely applied in prevention of hepatitis A epidemic in China and other countries now. It is essential to observe and confirm the vaccine immune efficacy, population antibody level and its persistent efficacy after mass immunization. METHODS A total of 220 children with negative anti-HAV(More)
This study was purposed to explore the relationship between asparagine synthetase (AsnS) mRNA expression level and the sensitivity of leukemic cell lines to L-asparaginase. The AsnS mRNA expression level in 8 cell lines (Jurkat, HL-60, U937, NB4, THP-1, Namalwa, Karpas299 and K562) was determined by real-time quantitative PCR (RQ-PCR) based on fluorescence(More)
Confined etchant layer technique (CELT) is an electro-and/ or photo- chemically induced chemical etching method for micromanufacture originated by our research group, which is distinguished from the LIGA and EFAB. To obtain the micro-/nano- meter precision, there are three strategies of CELT: (1) electro- and/or photo- chemical generation of etchant on the(More)
OBJECTIVE Early response to therapy is one of the most important prognostic factors in childhood acute lymphoblastic leukemia (ALL). This study aimed to assess the prognostic value of morphological assessment of bone marrow blasts during remission induction and determination of minimal residual disease (MRD) after remission induction. METHODS From January(More)
Premium power park (PPP) provides corresponding power supply for different levels of load using multiple PQDs, which is an effective measures to solve power quality problem. Existing international and regional or national power quality standards was given firstly. Then according to Premium Power Park user's feature, from the power supply capacity,(More)
OBJECTIVE To assess the prognostic value of both morphological persistent disease on day 19, on complete remission (CR) and minimal residual disease (MRD) in the bone marrow (BM) after multiagent remission induction therapy. METHODS From January 1998 to May 2003, 193 patients with newly diagnosed ALL were enrolled on protocol of ALL-XH-99. BM blast counts(More)
OBJECTIVE Minimal residual disease (MRD) is one of the most important prognostic factors in childhood acute lymphoblastic leukemia (ALL). Flow cytometry and PCR are two common techniques for examining MRD in ALL. This study aimed to identify MRD targets by tandem application of both techniques in children with ALL. METHODS From September 2001 to October(More)
The use of nonlinear power electronic loads and new energy power generations make harmonic injection to the grid inevitable, lead to transmission line more additional harmonic losses and significant economic losses. Based on the mechanism of harmonic losses, this paper derived current density distribution formula for transmission line, a more precise(More)
OBJECTIVE To assess the prognostic value of minimal residual disease (MRD) in childhood B-cell acute lymphoblastic leukemia (ALL) after induction chemotherapy. METHODS From September 2001 to October 2004, 102 patients with newly diagnosed B-ALL were enrolled in protocol ALL-XH-99. MRD after induction therapy, before high-dose methotrexate and early(More)
To explore the effects of tetra-arsenic tetra-sulfide (As(4)S(4)) in treatment of human chronic myelogenous leukemia K562 cells and its mechanism, trypan blue staining and microculture MTS assay were used to measure the effects of As(4)S(4) on growth inhibition of K562 cells; the morphologic change was determined by Wright's staining assay. The apoptosis(More)
