One certainty in software development is that requirements always evolve. To effectively handle requirements evolution, determining the impact of requirements evolution from quantitative perspectives is a breakthrough. This paper first defines labelled requirements and requirements models by array, which is simple and effective to express requirements or(More)
OBJECTIVE To investigate the efficacy and safety of temozolomide (TMZ) and lomustine (CCNU) in malignant brain gliomas. METHODS In this multicenter, randomized, double-blind, positive-controlled study, patients with malignant glioma of a histological grade III/IV were randomly divided into two groups. In experiment group, TMZ capsule 150 mg/m2 was given(More)
Wurtzite CdS and CdSe nanostructures with complex morphologies such as urchin-like CdS nanoflowers, branched nanowires, and fractal nanotrees can be produced via a facile solvothermal approach in a mixed solution made of diethylenetriamine (DETA) and deionized water (DIW). The morphologies of CdS and CdSe nanocrystals can be easily controlled via tuning the(More)
A bioactive ingredient in an ethanol extract from the branch bark of cultivated mulberry Husang-32 (Morus multicaulis Perr.) was isolated using a macroporous resin column. The primary component, which was purified by semi-preparative high-performance liquid chromatography diode array detection (HPLC-DAD), was identified as mulberroside A (MA) by liquid(More)
Selective synthesis of uniform single crystalline silver molybdate/tungstate nanorods/nanowires in large scale can be easily realized by a facile hydrothermal recrystallization technique. The synthesis is strongly dependent on the pH conditions, temperature, and reaction time. The phase transformation was examined in details. Pure Ag(2)MoO(4) and(More)
OBJECTIVE To analyze the outcome and prognosis of autologous hematopoietic stem cell transplantation (AHSCT) combined with high dose radiotherapy/chemotherapy in 22 patients with nasal NK/T cell lymphoma. METHODS From July 1992 to December 2005, 22 patients with nasal NK/T cell lymphoma were diagnosed pathologically. Immunophenotyping was performed in 13(More)
OBJECTIVE To investigate the effect of epirubicin on soluble CD25 (sCD25) secretion by CD4+CD25+ regulatory T (Treg) cells isolated from diffuse large B-cell lymphoma (DLBCL) patients. METHODS Treg cells were isolated from the peripheral blood mononuclear cells isolated from the newly diagnosed DBLCL patients. The concentration of sCD25 in the supernatant(More)
A microfluidic chip was designed to assess the toxicity of pollutants in a high-throughput way by using marine phytoplankton motility as a sensor signal. In this chip, multiple gradient generators (CGGs) with diffusible chambers enable large scale of dose-response bioassays to be performed in a simple way. Two mobile marine phytoplankton cells were confined(More)
Novel cage-like and electromagnetic functional polyaniline (PANI)/CoFe2O4 composite nanostructures, in which the self-assembled PANI nanofibers (approximately 15 nm in diameter) entwined around the octahedral CoFe2O4 magnet acting as the nucleation site or template, were successfully prepared by FeCl3 as either oxidant and dopant via a self-assembly(More)
OBJECTIVE To evaluate the role of nimotuzumab in combination with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC). METHODS The clinical data of 37 NSCLC patients who received nimotuzumab in combination with chemotherapy in Tianjin Medical University Cancer Hospital from January 2009 to October 2010 were retrospectively reviewed.(More)
