Objective: To evaluate the efficacy and safety of tigecycline in treating secondary infections of patients with hematological diseases.

Methods: A total of 85 cases of hematological patients with secondary infections were classified into empirical and targeted therapy groups. Empirical therapy group was composed of patients receiving tigecycline as an alternative due to ineffective anti-infection treatment for 3-5 days in the absence of microbiological evidence while those taking tigecycline based on microbiological evidence belonged to targeted therapy group.

Baffles are a key component of an airlift membrane bioreactor (MBR), which could enhance membrane surface shear for fouling control. In order to obtain an optimal hydraulic condition of the reactor, the effects of baffle location and size were systematically explored in this study. Computational fluid dynamics (CFD) was used to investigate the hydrodynamics in a bench-scale airlift flat sheet MBR with various baffle locations and sizes.

This study compared the efficacy of iodine-125 seed brachytherapy versus the conventional radiotherapy in patients with non-resectable stage III/IV non-small cell lung cancer. A total of 71 patients with inoperable advanced stages of lung cancer with tumor size ranging 5-10 cm were randomly assigned into two groups: Group A received the regional iodine-125 implantation (n = 35), and Group B received the conventional radiotherapy (n = 36). The isodose curves were obtained by the treatment planning system for patients in Group A.

When a globule with a complete symmetry (such as simple spherical droplets and concentric double emulsions) is transiting in a constriction tube, there is only one pattern of the transition. However, for a multiple-emulsion globule with asymmetric internal structures, there are many possible patterns with different pressure drops Δp due to various initial orientations of the inner droplets. In this paper, a boundary integral method developed recently is employed to investigate numerically the possible oriented transition of a globule with two unequal inner droplets in an axisymmetric microfluidic constriction.

The low butanol concentration of acetone-butanol-ethanol fermentation causes uneconomical product recovery. In this work, the effect of small molecule non-ionic surfactants on butanol fermentation was evaluated, using laboratory stocks of Clostridium acetobutylicum ATCC 824. Non-ionic surfactants substantially increased butanol production when additive amount was higher than 1% (W/W).

Autosomal dominant non-syndromic hearing loss (ADNSHL) is highly heterogeneous, among them, KCNQ4 is one of the most frequent disease-causing genes. More than twenty KCNQ4 mutations have been reported, but none of them were detected in Chinese mainland families. In this study, we identified a novel KCNQ4 mutation in a five generation Chinese family with 84 members and a known KCNQ4 mutation in a six generation Chinese family with 66 members.

In differential evolution (DE) studies, there are many parameter adaptation methods, aiming at tuning the mutation factor F and the crossover probability CR . However, these methods still cannot resolve the issues of population premature convergence and population stagnation. To address these issues, in this paper, we investigate the population adaptation regarding population diversity at the dimensional level and propose a mechanism named auto-enhanced population diversity (AEPD) to automatically enhance population diversity.

Objective: To investigate the changes of relative telomere length (RTL) of peripheral blood (PB) CD3⁺, CD3⁺CD4⁺, CD3⁺CD8⁺T lymphocytes, CD19⁺B lymphocytes and bone marrow (BM) CD34⁺ cells and its association with disease severity in untreated patients with immuno-related pancytopenia (IRP).

Methods: The PB CD3⁺ , CD3⁺ CD4⁺ , CD3⁺ CD8⁺ T lymphocytes, CD19⁺ B lymphocytes, and BM CD34⁺ cells were purified by magnetic activated cell sorting (MACS), and RTL were measured with flow-fluorescence in situ hybridization (FLOW-FISH).

Results: The RTL of CD3⁺, CD3⁺CD4⁺ , and CD3⁺CD8⁺T lymphocytes in untreated IRP patients were (27.

Objective: To explore the pathogenesis of abnormal WT1 expression in paroxysmal nocturnal hemoglobinuria (PNH).

Methods: The expression of WT1 mRNA in CD59⁻ and CD59⁺ bone marrow mononuclear cells (BMMNC) were measured by semi-quantitative reverse transcription PCR. After WT1 gene silence by RNA interference (RNAi) technology, biological characteristics of BMMNC were investigated by flow cytometry.

This study was purposed to detect the quantity and function of bone marrow (BM) T follicular helper (Tfh) cells of patients with immune thrombocytopenia, and to explore the role of Tfh cells in the pathogenesis of ITP. Twenty-one newly diagnosed ITP patients, twenty ITP patients in recovery stage and eighteen normal controls were enrolled in this study. The percentages of Tfh cells, Tfh-related molecules ICOS, CD40L, IL-21 in BM were detected by flow cytometry (FCM), and the mRNA expression of BCL-6 in BMMNC was determined by semi-quantitive RT-PCR.

TIM3, as a negative regulator of anti-tumor immunity, is highly expressed on LSCs, but not on normal HSCs. TIM3 on HSCs in MDS patients has not been clarified. Here, both the percentage of TIM3 on HSCs and the MFI of TIM3+ HSCs were higher in untreated MDS than control and were closed to AML, and excessive TIM3+ HSCs was closely related to clinical parameters: WPSS score, karyotype analysis, morphologic blasts, the number of cytopenia involving hematopoietic lineages, anemia and granulocytopenia.

A new method for imaging the tumor human vascular endothelial growth factor 165 (VEGF 165) is presented. A magnetic resonance imaging (MRI) probe was prepared by crosslinking ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles to the aptamer for tumor vascular endothelial growth factor 165 (VEGF165-aptamer). The molecular probe was evaluated for its in vitro and in vivo activities toward VEGF165.

Objective: Severe aplastic anemia (SAA) is a rare immune-regulated disease characterized by severe pancytopenia and bone marrow failure, caused by destruction of hematopoietic cells by the activated T lymphocytes. Linker for activation of T cells (LAT), a transmembrane adaptor protein, plays a key role in T-cell and mast cell functions. However, it remains unclear how LAT may change in patients with SAA.
