[Multicenter Prospective Study of Different Induction Regimens of Azacytidine in Treatment of Elderly Patients with Acute Myeloid Leukemia].

Objective: To observe the efficacy and safety of different induction regimens of same total dosage of azacitidine (Aza), including standard dose (standard dose group) and low-dose long-term (adjusted dose group), in the treatment of elderly acute myeloid leukemia (AML).

Methods: A total of 103 elderly patients with AML (non-acute promyelocytic leukemia) from January 2020 to June 2021 were enrolled. Aza was administered at the standard dose of 75 mg/(m·d) for 7 days in the standard dose group (50 cases), while at 100 mg/d for 7-12 days in the adjusted dose group (53 cases).

Catalyst-free photo-reductions of aromatic olefins and carbonyl compounds.

We describe herein a catalyst-free, traditional reductant-free strategy for the direct photoinduced hydrogenation or deuteration of aromatic olefins, ketones, and aldehydes with simple bases as the only additives. A broad range of substrates were demonstrated with high yields and deuterium incorporations. Mechanistic experiments indicate a radical mechanism.

Apatinib enhances chemosensitivity of acute myeloid leukemia hl60 cells to cytarabine by inducing apoptosis.

Purpose: To investigate the effect of apatinib combined with cytarabine on acute myeloid leukemia (AML) HL60 cells and its relevant mechanisms.

Methods: HL60 cells were treated with control, apatinib alone, cytarabine alone and apatinib combined with cytarabine. Cell proliferation in each group was detected via methy thiazolyl tetrazolium (MTT) assay, changes in the cell cycle and mitochondrial transmembrane potential in each group after treatment were detected via flow cytometry, and apoptosis was detected via Annexin V-PI double labeling.

High-dose dexamethasone vs prednisone for treatment of adult immune thrombocytopenia: a prospective multicenter randomized trial.

This study compared the efficacy and safety of high-dose dexamethasone (HD-DXM) and conventional prednisone (PDN) on the largest cohort to date as first-line strategies for newly diagnosed adult primary immune thrombocytopenia (ITP). Patients enrolled were randomized to receive DXM 40 mg/d for 4 days (n = 95, nonresponders received an additional 4-day course of DXM) or prednisone 1.0 mg/kg daily for 4 weeks and then tapered (n = 97).

Fish oil-supplemented parenteral nutrition could alleviate acute lung injury, modulate immunity, and reduce inflammation in rats with abdominal sepsis.

The objectives were to confirm that intravenous fish oil (FO) emulsions could alleviate acute lung injury, modulate immunity, and reduce inflammation in rats with abdominal sepsis and to explore the mechanisms of these effects. Thirty-six adult male Sprague-Dawley rats were divided into 4 groups randomly. Two days after central venous catheterization, rats were subjected to cecal ligation and puncture to produce abdominal sepsis.

[Prospective multicentre study of chemotherapeutic regimen containing pirarubicin on the treatment of relapsed or refractory acute myeloid leukemia in adults].

Objective: To compare the efficacy and toxicity of the chemotherapeutic regimen containing pirarubicin and mitoxantrone on the treatment of relapsed or refractory acute myeloid leukemia (AML) in adults.

Methods: In this open prospective multicentre study, we randomly assigned patients with relapsed or refractory AML to receive TAE regimen (pirarubicin+cytarabine+etoposide) versus MAE regimen (mitoxantrone + cytarabine + etoposide). The efficacy and toxicity were compared between the two groups.
