Background: Immune thrombocytopenia (ITP) is a common autoimmune disease characterized by loss of immune tolerance to platelet autoantigens leading to excessive destruction and insufficient production of platelets.
Method: Quantitative liquid chromatography tandem mass spectrometry (LC-MS/MS) was performed to detect the differentially expressed proteins in bone marrow samples from active ITP patients and normal controls.
Result: Our bioinformatic analysis identified two upregulated proteins (ORM1 and vWF) and two downregulated proteins (PPBP and SPARC) related to immune function.
Introduction: Adequate bowel preparation is key to a successful colonoscopy, which is necessary for detecting adenomas and preventing colorectal cancer. We developed an artificial intelligence (AI) platform using a convolutional neural network (CNN) model (AI-CNN model) to evaluate the quality of bowel preparation before colonoscopy.
Methods: This was a colonoscopist-blinded, randomized study.
Objective: To explore the diagnostic performance of blood urea nitrogen-to-creatinine (BUN/Cr) ratio in differentiating the site of gastrointestinal bleeding, and to assess the predictive value of early elevated BUN/Cr ratio for clinical outcomes in patients with acute nonvariceal upper gastrointestinal bleeding (ANVUGIB).
Methods: The adult patients diagnosed with gastrointestinal bleeding who were hospitalized in the Department of Gastroenterology, Zhongshan Hospital, Xiamen University between May 2020 and May 2021 were retrospectively enrolled. According to the site of gastrointestinal bleeding, the patients were divided into the upper gastrointestinal tract group, the proximal small intestinal bleeding group, and the distal small intestinal and colonic bleeding group.
Background: Although deubiquitinating enzymes (DUBs) such as CYLD, A20 and OTULIN are expressed in multiple tissues and thought to be linked with inflammatory diseases, their expression in periodontal tissues remains to be determined. This research was designed to assess the expression of CYLD, A20 and OTULIN in human gingiva, and to evaluate the regulation of these DUBs in human gingival fibroblasts (HGFs) upon different stimuli.
Methods: Immunohistochemistry assay was conducted to determine the expression of CYLD, A20 and OTULIN in human gingiva.
Background: Glioma is a type of tumor that usually occurs in the adult central nervous system. Protein kinases have become important targets for oncotherapy since they are closely correlated with signal transduction. The role of the casein kinase 1 (CK1) gene in glioma remains to be fully elucidated.
View Article and Find Full Text PDFT-cell lymphoma (TCL) is a group of heterogeneous disorders with a poor response to conventional treatment. In order to identify novel therapeutic targets, the present study investigated the effect of leptin and its receptor on glucose metabolism in TCL. The expression of the leptin receptor (ObR), and glucose transporter (Glut)1 and 4 was detected in TCL and reactive lymphoid hyperplasia (RLH) tissues by immunohistochemical analysis.

Methods: Mouse osteoblast-like (MC3T3-E1) cells were inoculated with a cell density of 70%. According to the grouping experimental design, Western blot and monodansylcadaverine (MDC) detection were conducted after dosing for 24 h.
Objective: Many studies suggest that high-fat diets are linked to the etiology of non-Hodgkin's lymphoma (NHL). However, the findings are inconsistent and therefore the association between fat and non-Hodgkin's lymphoma remains unclear. In this study, we aim to quantitatively assess the association between fat consumption and the risk for NHL.

The purpose of this study was to perform a meta-analysis examining the association of isocitrate dehydrogenase (IDH)1/2 mutations with overall survival (OS) and progression-free survival (PFS) in patients with glioblastomas. Medline, Cochrane, EMBASE, and Google Scholar were searched from inception to January 28, 2015, using combinations of the following keywords: IDH mutation, brain tumor, glioma, glioblastoma, oligodendroglioma, prognosis. Randomized controlled trials, and prospective and retrospective studies of patients with glioblastomas that provided IDH mutation and survival data were included.

Background: Numerous studies have confirmed that hyperbaric oxygen (HBO) in combination with radiotherapy or chemotherapy may increase the efficacy of radiotherapy or chemotherapy in patients with glioma. However, whether HBO therapy alone may inhibit or promote the growth of malignant tumors remains controversial. This study aimed to investigate the effect of HBO on the growth of glioma in rats, and the impact of HBO on the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1-alpha (HIF-1α), angiogenesis, and apoptosis of glioma cells.

Material And Methods: We randomly assigned 109 patients with hyperlipidemia and chronic periodontitis into group 1 (n = 55) and group 2 (n = 54). Patients in group 1 underwent a standard cycle of supragingival mechanical scaling and polishing.
Objective: This review was to evaluate the efficacy and toxicity of radiation therapy (RT) administered immediately after hyperbaric oxygen (HBO) therapy in patients with high grade gliomas.
Research Design And Methods: PubMed, Embase, ISI Web of Knowledge, and Cochrane databases were searched using combinations of the following search terms: radiotherapy, hyperbaric oxygenation, chemotherapy, glioma, brain tumor. Selection was limited to prospective studies involving patients given HBO followed by RT for high-grade gliomas.
Aim: To investigate biological mechanisms underlying pyruvate kinase M2 isoform (PKM2) regulation of cell migration and invasion in hepatocellular carcinoma cells.
Methods: HepG2 and Huh-7 hepatocellular carcinoma cell lines were stably transfected and cultured in DMEM (HyClone, Logan, UT, United States). To investigate the effects of PKM2 on cellular proliferation, hepatocellular carcinoma cells were subjected to the Cell Counting Kit-8 (Dojindo, Kamimashiki-gun, Kumamoto, Japan).

Objective: This study was aimed to investigate the risk factors of renal impairment and the predictive factors of renal function recovery so as to provide basis for its prevention and treatment.
Methods: Medical records of 161 patients with MM firstly diagnosed from January 2007 to April 2013 were analyzed retrospectively. Among them 58 cases accompanied with renal insufficiency (group A, others belong to group B) and 39 of them regain normal renal function after some treatment.
Previous studies have highlighted the role of genetic predispositions in disease, and several genes had been identified as important in Crohn's disease (CD). However, many of these genes are likely rare and not associated with susceptibility in Chinese CD patients. We found 294 shared identical variants in the CD patients of which 26 were validated by Sanger sequencing.

Ginkgolide B (GB) has been shown to exert neuroprotective effects against cerebral ischemia/reperfusion (I/R) injury. However, the underlying mechanism by which GB prevents ischemic cell death remains unclear. Lysosomal proteases, including cathepsins B and L, have been implicated in ischemic cell death following reperfusion.
