[The Mechanism of Artesunate Combined with Cytarabine and/or Daunorubicin on the Apoptosis of MV4-11 MLL-rearranged Acute Myeloid Leukemia Cell Line].

Objective: To investigate the effect and mechanism of artesunate (ARTS) combined with cytarabine(Ara-C) and/or daunorubicin (DNR) on the proliferation and apoptosis of MV4-11 human mixed-lineage leukemia rearranged（MLL-r） acute myeloid leukemia (AML) cell line.

Methods: CCK-8 assay was used to detect the proliferation effect of individual or in combination of ARTS, DNR, Ara-C on MV4-11 cells. The IC of ARTS, DNR and Ara-C was calculated separately.

A flow injection fluorescence "turn-on" sensor for the determination of metformin hydrochloride based on the inner filter effect of nitrogen-doped carbon dots/gold nanoparticles double-probe.

In this paper, an ultrasensitive and rapid "turn-on" fluorescence sensor, integrating flow-injection (FI) with nitrogen-doped carbon dots/gold nanoparticles (N-CDs/AuNPs) double-probe is established for the determination of metformin hydrochloride (MET) in biological fluids. The sensing strategy involves the weak inner filter effect between AuNPs and N-CDs due to aggregation products of MET with AuNPs. Unfortunately, the degree of AuNPs aggregation is difficult to control through manual assays, resulting in intolerable measurement error that limits further applications.

[Clinical Efficacy of R-EDOCH Protocol in the Treatment of Newly Diagnosed Double Expression Lymphoma].

Objective: To investigate the clinical efficacy of R-EDOCH protocol in the treatment of newly diagnosed double expression lymphoma.

Methods: The clinical data of 51 patients with newly diagnosed double expression lymphoma treated by R-EDOCH protocol were retrospectively analyzed in the period from May 2012 to October 2017, then overall remission rate (ORR), disease control rate (DCR), progression-free survival (PFS) rate and total survival (OS) rate were evaluated; moreover the patients were grouped according to IPI score and whether accepting hematopoietic stem cell transplantation(HSCT) and the clinical efficacy was compared.

Results: The ORR was 96.

Increased BMR in overweight and obese patients with type 2 diabetes may result from an increased fat-free mass.

The study aimed to determine the relationships between the basal metabolic rate (BMR) and body composition of overweight and obese Chinese adults with type 2 diabetes mellitus (DM). This cross-sectional clinical study enrolled 193 Chinese adults with type 2 DM who were overweight (24 kg/m(2)=BMI≤28 kg/m(2), n=99), or obese (BMI ≥28 kg/m(2), n=94). Ninety-seven adults with normal BMIs, including 50 DM patients and 47 healthy adults, were recruited as a control group.

[Pathogenic Genes of A Hereditary Hemorrhagic Telangiectasia Pedigree].

Objective: To identify the mutation of ENG and ALK1 genes in a hereditary hemorrhagic telangiectasia pedigree.

Methods: 14 exons of ENG gene and 9 exons of ALK1 gene in 11 menbers of this pedigree 4 generation were amplified by reverse transcription-polymerase chain reaction (RT-PCR), the PCR products were screened by direct sequencing.

Results: A nonsense mutation c.
