Background: The potential toxicity of Chinese herbal medicine has attracted more attention in recent years. Jueyin granules (JYG), a polyherbal formula, have been proven to be an effective agent for treating psoriasis in both animal models and clinical research. However, little is known about the possible acute and chronic toxicity of JYG.

Purification of Bone Marrow Clonal Cells from Patients with Myelodysplastic Syndrome via IGF-IR.

Malignant clonal cells purification can greatly benefit basic and clinical studies in myelodysplastic syndrome (MDS). In this study, we investigated the potential of using type 1 insulin-like growth factor receptor (IGF-IR) as a marker for purification of malignant bone marrow clonal cells from patients with MDS. The average percentage of IGF-IR expression in CD34+ bone marrow cells among 15 normal controls was 4.

Clinical outcome of treatment with a combined regimen of decitabine and aclacinomycin/cytarabine for patients with refractory acute myeloid leukemia.

We conducted a clinical trial of low-dose decitabine plus aclacinomycin/cytarabine (AA) treatment (DAA) for 20 patients with refractory/relapsed de novo acute myeloid leukemia (AML) or AML transformed from myelodysplastic syndrome (MDS/AML) in order to examine its efficacy and tolerability. Additionally, P15(ink4b) methylation status was analyzed (for 15 patients) pre- and post-DAA treatment, and in vitro drug sensitivity tests were performed for seven patients (AA or AA + decitabine) to explore the role of decitabine in this combination treatment regimen. A total of 11 patients (55.
