A life-threatening bleeding prediction model for immune thrombocytopenia based on personalized machine learning: a nationwide prospective cohort study.

Rare but critical bleeding events in primary immune thrombocytopenia (ITP) present life-threatening complications in patients with ITP, which severely affect their prognosis, quality of life, and treatment decisions. Although several studies have investigated the risk factors related to critical bleeding in ITP, large sample size data, consistent definitions, large-scale multicenter findings, and prediction models for critical bleeding events in patients with ITP are unavailable. For the first time, in this study, we applied the newly proposed critical ITP bleeding criteria by the International Society on Thrombosis and Hemostasis for large sample size data and developed the first machine learning (ML)-based online application for predict critical ITP bleeding.

Development and validation of a prediction model (AHC) for early identification of refractory thrombotic thrombocytopenic purpura using nationally representative data.

Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare and life-threatening haematological emergency. Although therapeutic plasma exchange together with corticosteroids achieve successful outcomes, a considerable number of patients remain refractory to this treatment and require early initiation of intensive therapy. However, a method for the early identification of refractory iTTP is not available.

To compare outcomes, patients with ICC were enrolled and categorized into the following adjuvant treatment modality groups: group 1, concurrent chemoradiotherapy (CCRT); group 2, sequential chemotherapy (CT) and radiotherapy (RT); and group 3, CT alone.

Chinese guidelines for treatment of adult primary immune thrombocytopenia.

Primary immune thrombocytopenia (ITP) is a bleeding disorder commonly encountered in clinical practice. The International Working Group (IWG) on ITP has published several landmark papers on terminology, definitions, outcome criteria, bleeding assessment, diagnosis, and management of ITP. The Chinese consensus reports for diagnosis and management of adult ITP have been updated to the 4th edition.

Overexpression of CD39 in hepatocellular carcinoma is an independent indicator of poor outcome after radical resection.

Nucleoside triphosphate diphosphohydrolase-1 (ENTPD1/CD39) is the rate-limiting enzyme in a cascade leading to the generation of immunosuppressive adenosine and plays an important role in tumor progression. This study aimed to evaluate the expression of CD39 and CD39Foxp3 regulatory T cells (Tregs) and to determine their prognostic role in patients with hepatocellular carcinoma (HCC) after radical resection.Immunohistochemistry (IHC) and double IHC were used to analyze CD39 expression or the expression of CD39 and Foxp3 in a cohort of 324 HCC patients who underwent curative resection.

Prognostic Value of the Modified Glasgow Prognostic Score in Patients Undergoing Radical Surgery for Hepatocellular Carcinoma.

Clinical significance and gene expression study of human hepatic stellate cells in HBV related-hepatocellular carcinoma.

Background: Peritumoral activated hepatic stellate cells (HSCs) are versatile myofibroblast-like cells closely related with hepatocellular carcinoma (HCC) progression. So far, comprehensive comparison of gene expression of human HSCs during hepatocarcinogenesis is scanty. Therefore, we identified the phenotypic and genomic characteristics of peritumoral HSCs to explore the valuable information on the prognosis and therapeutic targets of HBV related HCC.

Intratumoral regulatory T cells with higher prevalence and more suppressive activity in hepatocellular carcinoma patients.

Regulatory T cells (Treg) play a vital role in immunosuppressive crosstalk; however, Tregs from different locations lead to different clinical outcomes. Our aim was, therefore, to compare the prevalences and suppressive phenotypes of Tregs in the peripheral blood, peritumor, and intratumor of patients with hepatocellular carcinoma (HCC). METHODS : The frequencies and phenotypes of CD4(+) CD25(+) CD127(low/-) CD49d(-) Tregs in the periphery, peritumor, and intratumor of 78 HCC patients and 12 healthy controls were evaluated by flow cytometry.

[Impaired interleukin-10 secretion by CD5(+) B cells in patients with primary immune thrombocytopenia].

Objective: To investigate the number of peripheral blood CD5(+) B cells and their ability of secreting IL-10 in patients with immune thrombocytopenia (ITP).

Methods: Peripheral blood lymphocytes were isolated from 57 pre-treated, 40 post-treated ITP patients and 25 controls using Ficoll-Hypaque density centrifugation and then stained with PE-CD5/FITC-CD19 for flow cytometric analysis. After 24-hour culture, lymphocytes were stained with APC-IL-10 for intracellular cytokine detection.

High expression of IL-17 and IL-17RE associate with poor prognosis of hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is a typical malignancy in a background of chronic inflammation. Th17 cells (a major source of IL-17) constitute crucial components of infiltrating inflammatory/immune cells in HCC and can amplify inflammatory response via binding to interleukin-17 receptor (IL-17R). Thus, we investigated the expression and clinical significance of IL-17 and IL-17 receptor family cytokines in HCC.

The functional impairment of HCC-infiltrating γδ T cells, partially mediated by regulatory T cells in a TGFβ- and IL-10-dependent manner.

Background & Aims: The immunosuppressive network within the tumor microenvironment is one of the major obstacles to the success of cancer immunotherapy. γδ T cells are attractive effectors for cancer immunotherapy. Nevertheless, the promising anti-tumor effect in vitro is partially if not totally mitigated in vivo.

Interferon regulatory factor (IRF)-1 and IRF-2 are associated with prognosis and tumor invasion in HCC.

Background: Interferon regulatory factor (IRF)-1 and IRF-2 are transcriptional factors that mediate interferons functions; the loss of IRF-1 expression and gain of IRF-2 expression were associated with malignant phenotype in multiple cancers. However, their roles in the progression of hepatocellular carcinoma (HCC) remain poorly described.

Methods: Immunohistochemistry was used to analyze the nuclear expression of IRF-1/2 in a cohort of 332 HCC patients.

Background And Aim: The high expression of the galectin-1 predicts poor patient outcome in several tumors. The aim of this study was to investigate its prognostic value in patients with hepatocellular carcinoma (HCC) after resection.

Methods: Galectin-1 and tumor-infiltrating FoxP3(+) regulatory T cells (Tregs) were validated by tissue microarrays from HCC patients (n = 386) and statistically assessed for correlations with the clinical profiles and the prognosis of the patients.

Expression of TREM-1 in hepatic stellate cells and prognostic value in hepatitis B-related hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a typical inflammation-related malignancy characterized by high postoperative recurrence and metastasis. Although several inflammatory cells and inflammatory signatures have been linked to poor prognosis, the inflammation-associated molecular mechanisms of HCC development and progression are largely unknown. Here we show that triggering receptor expressed in myeloid cells (TREM)-1, a transmembrane receptor expressing in myeloid cells, was also expressed in tumor-activated hepatic stellate cells (HSCs) and associated with the aggressive behavior of HCC cells.

Polymorphisms in the promoter region of the CASP8 gene are not associated with non-Hodgkin's lymphoma in Chinese patients.

Caspase-8 (CASP8) involved in apoptosis plays an important role in mediating the normal regulation of cell proliferation, differentiation, inflammation, and homeostasis of multicellular organisms. Genetic polymorphisms, rs3834129 (-/CTTACT) and rs3769821 (T/C), in the promoter region of different CASP8 transcripts, were reported to be associated with genetic susceptibility of multiple cancers and non-Hodgkin's lymphoma (NHL), respectively. To investigate whether these two genetic variants, together with rs113686495 (-/CTGTCATT) which is 50 bp downstream of rs3769821, were associated with NHL in Chinese patients, we genotyped two cohorts of case and control samples from Kunming (case n = 64, control n = 133) and Shanghai (case n = 75, control n = 107).

[Conventional dose of prednisone regulates Th-associated gene expression in de novo ITP patients].

This study was aimed to investigate the T cell (helper T cells) immune status in ITP patients and its relation with therapeutic response. 20 de novo ITP patients were enrolled (8 males, 12 females) with a median age of 41 (20 to 81). Real-time RT-PCR method was used to measure the gene expression of Th cells including T-bet, IFN-γ, GATA-3, TGF-β, Foxp3, IL-2, IL-4 in PBMNC of ITP patients before and after conventional dose of prednisone therapy [1 mg/(kg·d)] and in PBMNC of 20 normal controls.

IDH1 and IDH2 mutations are frequent in Chinese patients with acute myeloid leukemia but rare in other types of hematological disorders.

Frequent mutations in the isocitrate dehydrogenase 1 and 2 genes (IDH1 and IDH2) have been identified in gliomas and acute myeloid leukemia (AML). Our aim is to assess whether IDH mutations were presented in Chinese patients with various hematological disorders. In this study, we screened the IDH1 and IDH2 mutations in a cohort of 456 Chinese patients with various hematological malignancies and disorders.
