Zinc oxide nanoparticles reduce the chemoresistance of gastric cancer by inhibiting autophagy.

Background: Gastric cancer (GC) is a common malignancy that results in a high rate of cancer-related mortality. Cisplatin (DDP)-based chemotherapy is the first-line clinical treatment for GC therapy, but chemotherapy resistance remains a severe clinical challenge. Zinc oxide nanoparticle (ZnO-NP) has been identified as a promising anti-cancer agent, but the function of ZnO-NP in GC development is still unclear.

Combing oncolytic adenovirus expressing Beclin-1 with chemotherapy agent doxorubicin synergistically enhances cytotoxicity in human CML cells in vitro.

Cancer virotherapy provides a new strategy to treat cancer that can directly kill cancer cells by oncolysis. Insertion of therapeutic genes into the genome of a modified adenovirus, thereby creating a so-called gene-virotherapy that shares the advantages of gene therapy and virotherapy. In this study we investigated whether a strategy that combines the oncolytic effects of an adenoviral vector with the simultaneous expression of the autophagy gene Beclin-1 offered a therapeutic advantage for chronic myeloid leukemia (CML) cells with resistance to chemotherapy and evaluated the synergistic effects of SG511-BECN and doxorubicin (Dox) in human CML cells in vitro.

Impact of Chemotherapy Delay on Overall Survival for AML with IDH1/2 Mutations: A Study in Adult Chinese Patients.

The effect of time from diagnosis to treatment (TDT) on overall survival of patients with acute myeloid leukemia (AML) remains obscure. Furthermore, whether chemotherapy delay impacts overall survival (OS) of patients with a special molecular subtype has not been investigated. Here, we enrolled 364 cases of AML to assess the effect of TDT on OS by fractional polynomial regression in the context of clinical parameters and genes of FLT3ITD, NPM1, CEBPA, DNMT3a, and IDH1/2 mutations.

Epigenetic priming with decitabine followed by low-dose idarubicin/cytarabine has an increased anti-leukemic effect compared to traditional chemotherapy in high-risk myeloid neoplasms.

Decitabine (DAC) is commonly used for the treatment of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Previous studies have indicated DAC sequentially combined with idarubicin was an effective treatment for myeloid neoplasms. Therefore, a clinical study was conducted of the sequential combination of DAC followed by low-dose idarubicin/cytarabine in high-risk myeloid neoplasms.

Hemolytic anemia as first presentation of Wilson's disease with uncommon ATP7B mutation.

Wilson's disease (WD) is a rare inherited disorder of copper metabolism and the main manifestations are liver and brain disorders. Hemolytic anemia is an unusual complication of WD. We describe a 15-year-old girl who developed hemolytic anemia as the first manifestation of Wilson's disease.

[Apoptosis of acute myeloid leukemia HL-60 cells induced by CDK inhibitor SNS-032 and its molecular mechanisms].

Objective: To investigate the effects of cycle-dependent kinase (CDK) inhibitor SNS-032 on apoptosis in human acute myeloid leukemia (AML) HL-60 cells and its molecular mechanisms.

Methods: Cultured AML HL-60 cells were treated with various concentrations of SNS-032. Cell apoptosis was determined with flow cytometry;cell viability was measured by MTT assay; the profiles of microRNA expression of HL-60 cells were analyzed by microRNA microarray;the protein expressions of JAK2/STAT3 pathway were detected by Western blotting.

[Optimal nighttime temperature for tomato plant in greenhouse in autumn and winter].

In order to investigate the effect of nighttime temperature (NT) on adult stage tomato plants in greenhouse, an experiment was conducted by using natural light growth chamber. Tomato plants were treated with 4 nighttime temperature as natural NT (CK), 14, 16, and 18 degrees C, on condition of the same daytime temperature (DT). Actual NT of CK, 14, 16, and 18 degrees C treatments were 13.

[Relationship between clinical characteristics and myelodysplastic syndrome patients with isocitrate dehydrogenase gene mutations].

Objective: To assess the prevalence and clinical characteristics of isocitrate dehydrogenase 1 and 2 (IDH 1 and IDH2) gene mutations in myelodysplastic syndrome (MDS) patients.

Methods: Pretreatment bone marrow specimens were enriched for mononuclear cells in 108 adult patients with de novo MDS from January 2006 to August 2012. Genomic DNA was extracted from mononuclear cells.

Clinical analysis of 240 patients with HLA-B27 associated acute anterior uveitis.

Purpose: To analyze the prevalence of HLA-B27 associated acute anterior uveitis and to identify its clinical features.

Methods: A total of 240 patients with HLA-B27 associated acute anterior uveitis, who were admitted to Zhejiang Ophthalmologic Hospital between December 2006 and October 2012, were retrospectively analyzed. The age of onset, sex, affected eyes, HLA-B27 antigen detection, recurrence, joint involvement, and surgical complications were investigated.

[The efficacy and safety of HAA regimen as induction chemotherapy in 150 newly diagnosed acute myeloid leukemia].

Objective: To explore the efficacy and safety of HAA regimen (homoharringtonine, cytarabine and aclarubicin) in the treatment of 150 newly diagnosed adult acute myeloid leukemia (AML).

Methods: All patients entered the study from May 1999 to June 2008 were treated with HAA regimen. Cox-survival analysis was used to estimate the survival rate and differences between M(1)/M(2) and M(4)/M(5) were compared with 2-sided log-rank test.

Novel influenza A (H1N1) in patients with hematologic disease.

Patients with hematologic disease are likely to be at increased risk for infection with influenza. We retrospectively analyzed 11 cases of patients with hematologic disease who were infected with pandemic H1N1 virus in our department, including their clinical manifestations, laboratory and imaging findings, outcomes of antiviral therapy, and factors associated with mortality. Notably, nine patients had lower respiratory tract disease.

FLT3 and NPM1 mutations in Chinese patients with acute myeloid leukemia and normal cytogenetics.

Mutations of fms-like tyrosine kinase 3 (FLT3) and nucleophosmin (NPM1) exon 12 genes are the most common abnormalities in adult acute myeloid leukemia (AML) with normal cytogenetics. To assess the prognostic impact of the two gene mutations in Chinese AML patients, we used multiplex polymerase chain reaction (PCR) and capillary electrophoresis to screen 76 AML patients with normal cytogenetics for mutations in FLT3 internal tandem duplication (FLT3/ITD) and exon 12 of the NPM1 gene. FLT3/ITD mutation was detected in 15 (19.
