Blood glucose mediated the effects of cognitive function impairment related to aluminum exposure in Chinese aluminum smelting workers.

Object: To explore the effects of occupational aluminum exposure on workers' cognitive function and blood glucose concentration, and to analyze whether blood glucose concentration can mediate the cognitive changes caused by aluminum.

Method: Our study recruited 375 workers from an aluminum factory in northern China. We collected the fasting elbow venous blood of the workers, measured their fasting blood glucose concentration (FBG), and used ICP-MS to determine plasma aluminum concentration (P-Al) as an indicator of internal exposure.

Cirsilineol attenuates LPS-induced inflammation in both in vivo and in vitro models via inhibiting TLR-4/NFkB/IKK signaling pathway.

The anti-inflammatory activity of cirsilineol in in vivo condition was assessed by measuring the relative organ weight, lung dry/wet weight ratio, protein concentration, and infiltration of inflammatory cells in bronchoalveolar lavage fluid. We estimated the myeloperoxidase activity and levels of cytokines, chemokines, and inflammatory markers to analyze the efficacy of cirsilineol against lipopolysaccharide (LPS)-induced lung inflammation. Furthermore, we quantified the gene expression of NFkB/IKK signaling molecules in cirsilineol-treated and untreated acute lung injury mice to confirm the anti-inflammatory property of cirsilineol.

Accurate diagnosis of colorectal cancer based on histopathology images using artificial intelligence.

Background: Accurate and robust pathological image analysis for colorectal cancer (CRC) diagnosis is time-consuming and knowledge-intensive, but is essential for CRC patients' treatment. The current heavy workload of pathologists in clinics/hospitals may easily lead to unconscious misdiagnosis of CRC based on daily image analyses.

Methods: Based on a state-of-the-art transfer-learned deep convolutional neural network in artificial intelligence (AI), we proposed a novel patch aggregation strategy for clinic CRC diagnosis using weakly labeled pathological whole-slide image (WSI) patches.

Stink bean () empty pod: a potent natural antidiabetic agent for the prevention of pancreatic and hepatorenal dysfunction in high fat diet/streptozotocin-induced type 2 diabetes in rats.

Downregulation of cytokeratin 18 enhances BCRP-mediated multidrug resistance through induction of epithelial-mesenchymal transition and predicts poor prognosis in breast cancer.

Multiple drug resistance (MDR) and metastasis have been identified as the two major causes of the poor prognosis of patients with breast cancer. However, the relationship between MDR and metastasis has not been characterized. Epithelial‑mesenchymal transition (EMT), a process known to promote metastasis in cancer, has been shown to be associated with the MDR phenotype of many tumor types.

Definitive Radiation Therapy Versus Postoperative Radiation Therapy for Patients With Maxillary Sinus Cancer Invading the Upper Jaw.

Maxillectomy following radiation therapy has the strongest local control over maxillary sinus cancer. However, in the advanced stage, complete resection is difficult with adequate margin and has the risk of functional disabilities after surgeries. The objective of the study was to determine the optimal treatment strategy for patients with maxillary sinus cancer invades the upper jaw.

Assessment of cholestasis in drug-induced liver injury by different methods.

Cholestasis in drug-induced liver injury (DILI) can be assessed by biochemical and pathologic methods, but the agreement between the 2 methods remains unclear.The aim of this study was to identify the accurate method for assessment of cholestasis in DILI.The DILI standard established and revised by the Council for International Organizations of Medical Sciences (CIOMS) (R values were calculated by liver function at different time points), cholestatic liver disease guideline (European Association for the Study of the Liver, EASL), and liver pathology were used to assess, compare, and analyze the cholestasis in 133 patients with DILI.

Intervertebral disc degeneration induced by long-segment in-situ immobilization: a macro, micro, and nanoscale analysis.

Background: Cervical spine fixation or immobilization has become a routine treatment for spinal fracture, dislocation, subluxation injuries, or spondylosis. The effects of immobilization of intervertebral discs of the cervical spine is unclear. The goal of this study was to evaluate the effects of long-segment in-situ immobilization of intervertebral discs of the caudal vertebra, thereby simulating human cervical spine immobilization.

Baicalein attenuates monocrotaline-induced pulmonary arterial hypertension by inhibiting endothelial-to-mesenchymal transition.

Aims: Endothelial-to-mesenchymal transition (EndoMT) was shown to lead to endothelial cell (EC) dysfunction in pulmonary arterial hypertension (PAH). Baicalein was reported to inhibit epithelial-to-mesenchymal transition (EMT), a biological process that has many regulatory pathways in common with EndoMT. Whether it can attenuate PAH by inhibiting EndoMT remains obscure.

[Research Advances of IDH2 Gene Mutation in Acute Myeloid Leukemia].

Acute myeloid leukemia (AML) is a malignant clonal hematologic disease from hematopoietic stem and progenitor cells. The isocitrate dehychogenase 2 (IDH2) gene mutation has been recently found, which may be associated with the course of AML. The incidence of IDH2 gene mutation in the patients with acute myeloid leukemia is high, especially in the AML patients with normal karyotype.

[Research advances on caspase-independent cell death of K562 cells].

Caspase independent cell death (CICD) is defined as death that ensues when a signal that normally induces apoptosis fails to activate caspases,it can be activated by PARP-1, Calpains, Bax and AIF, possessing distinctive biologic characteristic differed from apoptosis and necrosis. Recent researchs have found that the molecular mechanisms governing CICD of K562 is opposite from that of the traditional medicine killing leukemia cells, which may have the potential pharmaceutical point for new drugs. This article reviews the newly acquaintance of molecular mechanisms for CICD and recent studies concerning the induction death of K562 cells via CICD, so as to provide some reference for the research of new drug point.

[Th17 cells and aplastic anemia].

During the past few years, a novel family of CD4⁺T cell lineage was detected and named as Th17 cells because of its unique ability expressing IL-17, which also can produce IL-17A, IL-17F, IL-21, IL-22 and IL-26. Some cytokines, such as TGF-β, IL-6, L-23 may promote the differentiation of Th17 subset, whereas some cytokines, such as IL-21, IL-2, IFN-γ, may have inhibitory effects. Th17 cells serving as immune effectors play an important role in autoimmune diseases caused by chronic inflammation injury.

Preparation and application of collagen scaffold-encapsulated silver nanoparticles and bone morphogenetic protein 2 for enhancing the repair of infected bone.

The healing of contaminated/infected bone defects is a significant clinical challenge. Here, a novel collagen scaffold composite encapsulating silver nanoparticles (AgNP) and bone morphogenetic protein 2 (BMP-2) was prepared to enhance the healing of infected bone defects.
