T-cell lymphoma-associated hemophagocytic syndrome (T-LAHS) has been frequently reported in Asian countries and is considered with extremely poor prognosis. To summarize its clinical characteristics and explore its early diagnosis and treatment, we retrospectively analyzed the records of 113 patients with aggressive T cell lymphoma, of which 28 were(More)
Mesenchymal stem cells (MSCs) are multipotent stem cells that can generate various microenvironment components in bone marrow, ensuring a precise control over self-renewal and multilineage differentiation of hematopoietic stem cells. Nevertheless, their spatiotemporal correlation with embryonic hematopoiesis remains rudimentary, particularly in relation to(More)
We aimed to evaluate the association between 25-hydroxyvitamin D [25(OH) D] levels and both clinical severity at admission and outcome at discharge in patients with acute ischemic stroke (AIS). From June 2012 to October 2013, consecutive first-ever AIS patients admitted to the Department of Emergency of The Fourth Affiliated Hospital of Harbin Medical(More)
Meningiomas are the second most common intracranial tumours. Most meningiomas grow slowly; however, atypical and anaplastic meningiomas show an aggressive biological behaviour. Overexpression of growth factors is considered to be a cause of carcinogenesis. Midkine and pleiotrophin are heparin-binding growth factors that promote growth, survival, migration(More)
β-Thalassemia is one of the most common genetic blood diseases and is caused by either point mutations or deletions in the β-globin (HBB) gene. The generation of patient-specific induced pluripotent stem cells (iPSCs) and subsequent correction of the disease-causing mutations may be a potential therapeutic strategy for this disease. Due to the low(More)
More than 50% of human tumors contain a mutation in p53. Over 90% of tumors are solid tumors. Solid tumors have low oxygenated regions, called hypoxic regions where the tumor cells are more resistant to radio- and chemo-therapy than their well-oxygenated counterparts. In this study, we constructed a cell-permeable p53 fusion protein with selective stability(More)
Apoptosis plays a key role in many biological processes, including homeostasis within the immune system. A family of cysteine proteases, the caspases, constitutes the core of the apoptotic machinery. We have characterized the first bivalve caspase-8 ortholog from the Hong Kong oyster Crassostrea hongkongensis (designated ChCaspase-8). The full-length cDNA(More)
Oct4 protein encoded by POU5F1 plays a pivotal role in maintaining the self‑renewal of pluripotent stem cells; however, its presence in cancer cells remains controversial. In the present study, we provided evidence that the transcripts of authentic OCT4 gene (OCT4A) and its multiple pseudogenes were detected in a variety of cancer cell lines. A few major(More)
A hairpin molecular beacon tagged with carboxyfluorescein in combination with graphene oxide as a quencher reagent was used to detect the DNA damage by chemical reagents. The fluorescence of molecular beacon was quenched sharply by graphene oxide; while in the presence of its complementary DNA the quenching efficiency decreased because their hybridization(More)
