Seven-years post allogeneic hematopoietic stem cell transplantation pure red cell aplastic anemia cured with daratumumab: A case report and review of literature.

Background: Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) is currently the only viable method of curing patients with acute myeloid leukaemia. In 30% to 50% of patients, donors and recipients have some level of ABO blood group incompatibility. ABO blood group incompatibility can cause antibodies against the donor's red blood cells to persist in the recipient's body, resulting in a delay of several months in the recovery of red blood cells.

[Progress and Trend of CAR-T and PD-1 Blockade in the Treatment of Acute Myeloid Leukemia--Review].

Abstract　　Acute myeloid leukemia (AML) is a malignant clonal proliferative hematological tumor that originates from hematopoietic stem progenitor cells. Traditional chemotherapy can achieve complete remission in most patients, but so far, only allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only way to cure AML. Recurrence, drug resistance, and transplant-related deaths remain a key issue for AML treatment.

[Potential Value of Cancer-Associated Fibroblasts in Hematological Malignancies--Review].

Cancer-associated fibroblasts (CAF), as one of the most important components of tumor microenvironment, which plays important role in tumorigenesis, development, infiltration and metastasis of cancers. In a variety of solid tumors, CAF can even determine the fate of tumor cells. In view of its pivotal role in promoting tumor progression, CAF has recently become a therapeutic target for a variety of tumors.

Three-year Follow-up on the Safety and Effectiveness of Rituximab Plus Chemotherapy as First-Line Treatment of Diffuse Large B-Cell Lymphoma and Follicular Lymphoma in Real-World Clinical Settings in China: A Prospective, Multicenter, Noninterventional Study.

Background: Prospective real-life data on the safety and effectiveness of rituximab in Chinese patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) are limited. This real-world study aimed to evaluate long-term safety and effectiveness outcomes of rituximab plus chemotherapy (R-chemo) as first-line treatment in Chinese patients with DLBCL or FL. Hepatitis B virus (HBV) reactivation management was also investigated.

AMPK signaling in the nucleus accumbens core mediates cue-induced reinstatement of cocaine seeking.

Relapse to drug seeking can be caused by exposure to drug-associated cues, provoking drug craving even after prolonged abstinence. Recent studies demonstrated that AMP-activated protein kinase (AMPK) regulates neuronal morphology and membrane excitability in neurons. Here, we investigated the role of AMPK activity in the nucleus accumbens (NAc) in relapse to cocaine seeking.

A phase 2 study of methotrexate, etoposide, dexamethasone, and pegaspargase chemotherapy for newly diagnosed, relapsed, or refractory extranodal natural killer/T-cell lymphoma, nasal type: a multicenter trial in Northwest China.

The nasal type of extranodal natural killer/T-cell lymphoma is a rare aggressive lymphoma with poor prognosis. To discover a successful treatment, we investigated the efficacy and safety of chemotherapy with methotrexate, etoposide, dexamethasone, and polyethylene glycol-asparaginase (MESA). Three cycles of MESA were administered to 46 patients with new or relapsed/refractory natural killer/T-cell lymphoma.

[Effect of Decitabine on DKK1 Gene Demethylation in Leukemia Cells].

Objective: To explore the effect of decitabine on Dickkopf-1 (DKK1) gene expression level and its downstream Wnt signaling pathway in acute myeloid leukemia (AML) cell line HL-60.

Methods: Flow cytometry and DNA ladder analysis were performed to detect apoptosis in HL-60 cell treated with different concentration of decitabine. Methylation-specific polymerase chain reaction (MS-PCR) was used to examine the methylation status of DKK1 gene.

AMPK Signaling in the Dorsal Hippocampus Negatively Regulates Contextual Fear Memory Formation.

Both the formation of long-term memory (LTM) and dendritic spine growth that serves as a physical basis for the long-term storage of information require de novo protein synthesis. Memory formation also critically depends on transcription. Adenosine monophosphate-activated protein kinase (AMPK) is a transcriptional regulator that has emerged as a major energy sensor that maintains cellular energy homeostasis.

[Research Progress on DKK1 Gene in Leukemia].

A number of studies have demonstrated that the methylation of Dickkopf-1 (DKK1) gene promoter is related with the occurrence and development of many neoplastic diseases. By means of binding with corresponding receptors, DKK1 blocks the transduction pathway of Wnt/β-catenin/TCF and inhibits the proliferation and invasion of tumor cells, inducing apoptosis. Leukemia is a hyperplastic disease of hematopoietic stem cell malignant clone.

Role of hippocampal β-adrenergic and glucocorticoid receptors in the novelty-induced enhancement of fear extinction.

Fear extinction forms a new memory but does not erase the original fear memory. Exposure to novelty facilitates transfer of short-term extinction memory to long-lasting memory. However, the underlying cellular and molecular mechanisms are still unclear.

Delayed noradrenergic activation in the dorsal hippocampus promotes the long-term persistence of extinguished fear.

Fear extinction has been extensively studied, but little is known about the molecular processes that underlie the persistence of extinction long-term memory (LTM). We found that microinfusion of norepinephrine (NE) into the CA1 area of the dorsal hippocampus during the early phase (0 h) after extinction enhanced extinction LTM at 2 and 14 days after extinction. Intra-CA1 infusion of NE during the late phase (12 h) after extinction selectively promoted extinction LTM at 14 days after extinction that was blocked by the β-receptor antagonist propranolol, protein kinase A (PKA) inhibitor Rp-cAMPS, and protein synthesis inhibitors anisomycin and emetine.

Stress within a restricted time window selectively affects the persistence of long-term memory.

The effects of stress on emotional memory are distinct and depend on the stages of memory. Memory undergoes consolidation and reconsolidation after acquisition and retrieval, respectively. Stress facilitates the consolidation but disrupts the reconsolidation of emotional memory.
