A primary pediatric acute myelomonocytic leukemia with t(3;21)(q26;q22): A case report.

Rationale: The rare t(3;21)(q26;q22) translocation results in gene fusion and generates multiple fusion transcripts, which are typically associated with therapy-related myelodysplastic syndrome, acute myeloid leukemia, and chronic myelogenous leukemia. Here, we report a rare case of de novo acute myelomonocytic leukemia in a young child with t(3;21)(q26;q22).

Patient Concerns: A 2-and-a-half-year-old female patient presented with abdominal pain, cough, paleness, and fever for 3 weeks, without any history of malignant diseases.

Two novel species and three new records of Torulaceae from Yunnan Province, China.

While investigating the diversity of lignicolous fungi in Yunnan Province, China, six fresh collections of Torulaceae were collected and identified based on morphological examination and phylogenetic analyses of combined LSU, ITS, SSU, , and sequence data. Two new species, and , and three new records, (new freshwater habitat record), (new host record), and (new freshwater habitat record) are reported. Detailed descriptions, illustrations, and a phylogenetic tree to show the placement of these species are provided.

How does patient-centered hospital culture affect clinical physicians' medical professional attitudes and behaviours in chinese public hospitals: a cross-sectional study?

Background: An increasing number of studies on physicians' professionalism have been done since the 2002 publication of Medical Professionalism in the New Millennium: A Physician Charter. The Charter proposed three fundamental principles and ten responsibilities. However, most studies were done in developed countries, and few have been done in China.

The prevalence and characteristics of alexithymia in patients with type 2 diabetes mellitus: A systematic review and meta-analysis.

Background: Alexithymia is common in patients with type 2 diabetes mellitus (T2DM). Although the estimated prevalence of alexithymia in patients with T2DM is widely reported, these results have not been synthesized.

Aim: To systematically assess the prevalence and characteristics of alexithymia in patients with T2DM.

Multisite Pseudomonas aeruginosa Infections Detected by Metagenomic Next-Generation Sequencing in a Child with Aplastic Anemia: A Case Report.

Microbial cultivation is the current gold standard for the clinical diagnosis of bacterial infections. However, this method sometimes produces false negative results. We present a case study of multisite Pseudomonas aeruginosa infections detected by metagenomic next-generation sequencing in a child with aplastic anemia, highlighting the rapid and accurate advantages of this technique.

CXCR4 protects bone marrow-derived endothelial progenitor cells against hypoxia through the PI3K/Akt signaling pathway.

The present study aimed to investigate the regulatory mechanism of chemokine (C-X-C motif) receptor 4 (CXCR4) on endothelial progenitor cells (EPCs) through the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway under hypoxic conditions. Mononuclear cells were isolated from the bone marrow (BM) of young Sprague-Dawley (SD) rats. Bone marrow-derived endothelial progenitor cells (BM-EPCs) were characterized by using Dil-labeled acetylated low-density lipoprotein (Dil-ac-LDL) and fluorescein isothiocyanate-labeled UEA (FITC-UEA-1).

Low expression of NTF3 is associated with unfavorable prognosis in hepatocellular carcinoma.

Neurotrophin 3 (NTF3) is a member of the nerve growth factor (NGF) family involved in cancer progression, including medulloblastoma and breast cancer. However, the expression and prognostic value of NTF3 has not been reported in human hepatocellular carcinoma (HCC). Here, we first performed an mRNA expression analysis of the NTF family using the TCGA database and found that NTF3 was significantly downregulated in patients with HCC.

Quality Management Model for Phase I Clinical Drug Trials: A Structural Equation Model.

This study aimed to construct a quality management model for phase I clinical drug trials. A cross-sectional survey was conducted and data were collected from 604 respondents at 69 institutions in China engaged in phase I clinical drug trials. Exploratory and confirmatory factor analyses were used to develop the survey tool.

Association of body composition with survival and inflammatory responses in patients with non-metastatic nasopharyngeal cancer.

Objectives: It is unknown whether or not the body composition is correlated with the prognosis and inflammatory response in patients with nasopharyngeal cancer (NPC).

Materials And Methods: This cohort included 1767 patients with NPC. Visceral, subcutaneous and intra muscular adipose tissues (VAT, SAT and IMAT), and skeletal muscle index were quantified with computed tomography.

Anticancer-Active N-Heteroaryl Amines Syntheses: Nucleophilic Amination of N-Heteroaryl Alkyl Ethers with Amines.

A mild amination protocol of N-heteroaryl alkyl ethers with various amines is described. This transformation is achieved by utilizing simple and readily available base as promoter via C-O bond cleavage, offering a new amination strategy to access several anticancer-active compounds. This work is highlighted by the excellent functional group compatibility, scalability, wide substrate scope, and easy derivatization of a variety of drugs.

PBK overexpression promotes metastasis of hepatocellular carcinoma via activating ETV4-uPAR signaling pathway.

Invasion and metastasis are the predominant causes of lethal outcomes in patients with hepatocellular carcinoma (HCC). However, the molecular mechanism underlying the invasive or metastatic process are still insufficiently understood. Here, we first integrated several public databases and identified a novel protein kinase, PDZ-binding kinase (PBK) that was frequently upregulated and correlated with poor prognosis in patients with HCC.

Association of low skeletal muscle index with increased systematic inflammatory responses and interferon γ-induced protein 10 levels in patients with colon cancer.

Background: Skeletal muscle depletion is a prognostic factor in patients with cancer. Here, we evaluated the association between the skeletal muscle index (SMI) and local and systemic responses in patients with colon cancer.

Patients And Methods: We analyzed the relationships of the SMI with neutrophil, lymphocyte, monocyte, and platelet counts; the neutrophil-to-lymphocyte ratio; albumin levels; and C-reactive protein levels in a cohort of 561 patients, and with the circulating levels of 39 cytokines in a cohort of 125 patients.

Solid neuroendocrine breast carcinoma: mammographic and sonographic features in thirteen cases.

This study aimed to determine and quantitate the mammographic and sonographic characteristics in 13 cases of solid neuroendocrine breast carcinoma (NEBC) and to analyze the association of radiological findings with the clinical and histopathologic findings. The clinical data and imaging findings of 13 female patients with histologically confirmed solid NEBC were reviewed. Imaging data were evaluated by two radiologists for a consensual diagnosis.

[Inhibition of intracellular Ca(2+)-chelating agent on Hela cell apoptosis induced by HSV-1].

Aim: To explore the variation of intracellular free-Ca (2+) concentration during Hela cell apoptosis induced by HSV-1 and inhibition of Ca(2+)-chelating agent on the apoptosis.

Methods: Apoptosis of the Hela cells infected by HSV-1 was observed under scanning electron microscope (SEM) and transmission electron microscope (TEM), and the variation of intracellular free-Ca (2+) concentration, labeled with fluorescent probe was observed under fluorescence-microscope at a series of timepoints.

Results: The Hela cells infected by HSV-1 showed typical apoptotic morphological changes.
