Acute stress induces an inflammation dominated by innate immunity represented by neutrophils in mice.

It is well known that psychological stress could affect the immune system and then regulate the disease process. Previous studies mostly focused on the effects of chronic stress on diseases and immune cells. How acute stress affects the immune system remains poorly understood.

LncRNA ANRIL promotes cell growth, migration and invasion of hepatocellular carcinoma cells via sponging miR-144.

Antisense non-coding RNA in the INK4A locus (ANRIL) has been recognized as a cancer-related lncRNA in hepatocellular carcinoma previously. This study aimed to reveal the functional effects and mechanisms of ANRIL on hepatocellular carcinoma cells in vitro. The expression of ANRIL in hepatocellular carcinoma cell lines (MHCC97 and Li-7) and non-tumourigenic liver cell line THLE-3 was detected by qRT-PCR.

Silence of lncRNA HEIH suppressed liver cancer cell growth and metastasis through miR-199a-3p/mTOR axis.

Background/aims: High expression in hepatocellular carcinoma (HEIH) is an long noncoding RNA (lncRNA) which is highly expressed in hepatocellular carcinoma (HCC). Aberrant expression of HEIH is implicated in regulating HCC cells growth and metastasis. This study attempted to illustrate the effects of HEIH on HCC cell lines.

MicroRNA-494 regulates Gli3 expression and inhibits pancreatic cancer cells growth and migration.

MicroRNA (miR)-494 has been identified as a predictor and inhibitor in pancreatic cancer. This study aimed to explore the role of miR-494 in pancreatic cancer cells, and the regulation of glioma-associated oncogene 3 (Gli3) by miR-494. The mRNA level of Gli3 in 99 pairs of pancreatic cancer and correspondingly adjacent tissues was monitored by qRT-PCR.

A distinct clinicopathological variant of focal cortical dysplasia IIId characterized by loss of layer 4 in the occipital lobe in 12 children with remote hypoxic-ischemic injury.

Objective: In 2011, the International League Against Epilepsy (ILAE) proposed a consensus classification system of focal cortical dysplasia (FCD) to distinguish clinicopathological subtypes, for example, "isolated" FCD type Ia-c and IIa-b, versus "associated" FCD type IIIa-d. The histopathological differentiation of FCD type I and III variants remains, however, a challenging issue in everyday practice. We present a unique histopathological pattern in patients with difficult-to-diagnose FCD, which highlights this dilemma, but also helps to refine the current ILAE classification scheme of FCD.

Cerebellar hemangioblastoma mimicking an aneurysm: A case report and literature review.

Hemangioblastomas (HBMs) are highly vascular tumors of the central nervous system. Sporadic HBMs are nearly always solitary, and solitary HBMs are similar to intracranial arteriovenous malformations due to their highly vascular characteristics. However, to the best of our knowledge, cases of HBM in the cerebellum mimicking an aneurysm have never been reported in the literature.

Extraventricular neurocytoma in the left temporal lobe: A case report and review of the literature.

Central neurocytoma (CNC) often develops in the ventricular system adjacent to the interventricular foramen and septum pellucidum. According to the World Health Organization, CNCs are classified as grade II tumors, and in recent years it has been reported that CNCs have occasionally occurred in rare areas of the central nervous system. The current study describes a rare case of CNC located in the left temporal lobe of a 49-year-old man, who had been experiencing headaches for 3 weeks.

Macrophages transfer antigens to dendritic cells by releasing exosomes containing dead-cell-associated antigens partially through a ceramide-dependent pathway to enhance CD4(+) T-cell responses.

Defects in rapid clearance of apoptotic cells lead to an accumulation of dead cells (late apoptotic or secondary necrotic cells), which results in an aberrant immune response. However, little is known about whether and how macrophages (Mφs) cooperate with dendritic cells (DCs) in the presentation of dead-cell-associated antigens in this process. By transferring high numbers of dead cells to mimic a failure of apoptotic cell clearance in vivo, we found that Mφs and neutrophils were the predominant phagocytes in the uptake of dead cells in the spleen.

Adenovirus with p16 gene exerts antitumor effect on laryngeal carcinoma Hep2 cells.

Laryngeal cancer is an uncommon form of cancer. The tumor suppressor P16, known to be mutated or deleted in various types of human tumor, including laryngeal carcinoma, is involved in the formation and development of laryngeal carcinoma. It has been previously reported that the inactivation or loss of P16 is associated with the acquisition of malignant characteristics.

NK cells promote neutrophil recruitment in the brain during sepsis-induced neuroinflammation.

Sepsis could affect the central nervous system and thus induces neuroinflammation, which subsequently leads to brain damage or dysfunction. However, the mechanisms of generation of neuroinflammation during sepsis remain poorly understood. By administration of lipopolysaccharides (LPS) in mice to mimic sepsis, we found that shortly after opening the blood-brain barrier, conventional CD11b(+)CD27(+) NK subset migrated into the brain followed by subsequent neutrophil infiltration.

Programmed Death Ligand-1 on Microglia Regulates Th1 Differentiation via Nitric Oxide in Experimental Autoimmune Encephalomyelitis.

Microglia are considered to be potential antigen-presenting cells and have the ability to present antigen under pathological conditions. Nevertheless, whether and how microglia are involved in immune regulation are largely unknown. Here, we investigated the suppressive activity of microglia during experimental autoimmune encephalomyelitis (EAE) induced by myelin oligodendrocyte glycoprotein, with the goal of understanding their role in regulating the T cell reaction.

Sturge-Weber Syndrome Is Associated with Cortical Dysplasia ILAE Type IIIc and Excessive Hypertrophic Pyramidal Neurons in Brain Resections for Intractable Epilepsy.

Sturge-Weber syndrome (SWS) is a rare syndrome characterized by capillary-venous malformations involving skin and brain. Many patients with SWS also suffer from drug-resistant epilepsy. We retrospectively studied a series of six SWS patients with epilepsy and extensive neurosurgical resections.

Peroxiredoxin 3 is a novel marker for cell proliferation in cervical cancer.

Although peroxiredoxin 3 (Prx3) has been reported to be involved in cervical cancer (CC) carcinogenesis, the significance of Prx3 in CC progression remains unclear. The present study was conducted to investigate the expression features of Prx3 to better understand the mechanism of tumor growth and invasion. Sixty-eight patients with invasive squamous cervical cancer were included in the present study.

[Pathologic features of ulegyria in refractory epilepsy by modified anatomic hemispherectomy: a clinicopathologic study of 39 cases].

Objective: To investigate the clinicopathologic features of the brain tissue diagnosed as ulegyria from modified anatomic hemispherectomy for refractory epilepsy.

Methods: The clinical and pathologic findings were reviewed in 39 patients who underwent modified anatomic hemispherectomy and diagnosed as ulegyria in the Epilepsy Center of Tsinghua University Yuquan Hospital from 2007 to 2011.

Results: All patients including 30 males and 9 females had medically intractable seizures, and the mean age of seizure onset and disease duration were 4.

[Inhibitory effect of tripeptide compound tyroservaltide on invasion and metastasis of mouse melanoma cell line B16-F10].

Background & Objective: Tripeptide compound tyroservaltide (YSV) has obvious inhibitory effect on experimental liver cancer. This study was to evaluate the inhibitory effect of YSV on the invasion and metastasis of mouse melanoma cell line B16-F10.
