Xpert MTB/RIF Assay for the Diagnosis of Lymph Node Tuberculosis in Children: A Systematic Review and Meta-Analysis.

: Lymph node tuberculosis (LNTB) is the leading type of extrapulmonary tuberculosis (EPTB) causing death in children. The Xpert MTB/RIF assay is a novel rapid test for the diagnosis of LNTB. Although previous evidence suggests that Xpert is reliably accurate in diagnosing EPTB in children, information is lacking for the specific type of LNTB in children.

Case Report: Niraparib-Related Pulmonary Embolism During the Treatment of Mutant Advanced Ovarian Cancer.

Niraparib, an oral, potent, highly selective poly (ADP-ribose) polymerase (PARP) inhibitor, has promising clinical benefit for maintenance treatment of patients with ovarian cancer in partial response to platinum-based chemotherapy, especially in patients with mutation. In publicly available niraparib treatment-related adverse events, gastrointestinal disorders and hematological toxicities were most commonly reported with manageable safety profile. Herein, we first describe a severe and never-reported pulmonary embolism (PE) associated with the use of niraparib in a patient with mutation advanced high-grade serous ovarian cancer and received anticoagulant therapy after PE.

Overexpression of miR-1290 contributes to cell proliferation and invasion of non small cell lung cancer by targeting interferon regulatory factor 2.

MicroRNAs are small endogenous non-coding RNAs, which can frequently emerge as regulators in many cancer types. MiR-1290 was found to be abnormally elevated in non small cell lung cancer (NSCLC). However, the underlying molecular mechanism still needs to be investigated.

Metformin is associated with survival benefit in pancreatic cancer patients with diabetes: a systematic review and meta-analysis.

Background: Pancreatic cancer is a highly lethal disease with a poor prognosis while metformin has been associated with a decreased risk of pancreatic cancer. Although the benefit of metformin was observed for pancreatic cancer prevention, it is not clear whether it can also affect the survival of pancreatic cancer patients with type 2 diabetes mellitus. A systematic review and meta-analysis was conducted to assess the effect of metformin on the survival of pancreatic cancer patients with type 2 diabetes mellitus.

β-adrenoreceptor Inverse Agonist Down-regulates Muscarine Cholinergic Subtype-3 Receptor and Its Downstream Signal Pathways in Airway Smooth Muscle Cells in vitro.

Mechanisms underlying β-adrenoreceptor (βAR) inverse agonist mediated bronchoprotectiveness remain unknown. We incubated ICI118,551, formoterol, budesonide, and formoterol plus budesonide, as well as ICI118,551 or pindolol plus formoterol, ICI118,551 plus forskolin, SQ22,536 or H89 plus formoterol in ASMCs to detect expressions of MR, PLCβ and IP. The level of MR in the presence of 10 mmol/L ICI118,551 were significantly decreased at 12 h, 24 h and 48 h (P < 0.

The preventive effects of hyperoside on lung cancer in vitro by inducing apoptosis and inhibiting proliferation through Caspase-3 and P53 signaling pathway.

Though advanced surgical operation and chemotherapy have been under taken, lung cancer remains one of the most aggressive and fatal human malignancies with a low survival rate. Thus, novel therapeutic strategies for prevention and remedy are urgently needed in lung cancer. Hyperoside, known as quercetin-3-O-β-d-galactopyranoside, is a natural flavonol glycoside discovered in plants of genera Hypericum, displaying anti-oxidant, anticancer, and anti-inflammatory properties.

MicroRNA-524-5p suppresses the growth and invasive abilities of gastric cancer cells.

Previous studies have demonstrated that microRNAs (miRNAs) are associated with tumor development and progression. miRNA-524-5p (miR-524-5p) has been reported to be involved in the development and progression of several types of cancer, but its role in gastric cancer has not been fully elucidated to date. Therefore, the aim of the present study was to investigate the expression levels and function of miR-524-5p in human gastric cancer.

Exome sequencing identifies somatic mutations of DDX3X in natural killer/T-cell lymphoma.

Natural killer/T-cell lymphoma (NKTCL) is a malignant proliferation of CD56(+) and cytoCD3(+) lymphocytes with aggressive clinical course, which is prevalent in Asian and South American populations. The molecular pathogenesis of NKTCL has largely remained elusive. We identified somatic gene mutations in 25 people with NKTCL by whole-exome sequencing and confirmed them in an extended validation group of 80 people by targeted sequencing.

A long-acting β2-adrenergic agonist increases the expression of muscarine cholinergic subtype‑3 receptors by activating the β2-adrenoceptor cyclic adenosine monophosphate signaling pathway in airway smooth muscle cells.

The persistent administration of β2‑adrenergic (β2AR) agonists has been demonstrated to increase the risk of severe asthma, partly due to the induction of tolerance to bronchoprotection via undefined mechanisms. The present study investigated the potential effect of the long‑acting β2‑adrenergic agonist, formoterol, on the expression of muscarinic M3 receptor (M3R) in rat airway smooth muscle cells (ASMCs). Primary rat ASMCs were isolated and characterized following immunostaining with anti‑α‑smooth muscle actin antibodies.

A simple kinetic model for myeloma cell culture with consideration of lysine limitation.

A simple kinetic model is developed to describe the dynamic behavior of myeloma cell growth and cell metabolism. Glucose, glutamine as well as lysine are considered as growth limiting substrates. The cell growth was restricted as soon as the extracellular lysine is exhausted and then intracellular lysine becomes a growth limiting substrate.

The study was aimed to investigate the BCL-XL expression and mutation, and its clinical significance in non-Hodgkin's lymphoma. Lymphoma cells were selectively isolated by laser microdissection. BCL-XL expression from lymphoma tissue and microdissected lymphoma cells was measured by using real-time quantitative reverse transcription-polymerase chain reaction.

Specific tissue expression and cellular localization of human apolipoprotein M as determined by in situ hybridization.

Apolipoprotein M (apoM) is a recently discovered human apolipoprotein predominantly present in high-density lipoprotein (HDL), and in minor proportion in triglyceride-rich lipoprotein (TGRLP) and low-density lipoprotein (LDL). The gene coding for apoM has been detected in all mammal genomes. The function of apoM is unknown yet.
