Objective: Cerebral microbleeds (CMBs) are punctate hemorrhagic lesions within the brain parenchyma and are a classic manifestation of cerebral small vessel disease (CSVD). The primary objective of this study is to investigate the potential role of miR-4685-3p and underlying mechanisms by which miR-4685-3p modulates matrix metalloproteinase-9 (MMP9) in cerebral microvascular endothelial cell injury.
Methods: We employed high-throughput sequencing to screen for differentially expressed miRNAs in the peripheral blood of patients with CMBs and healthy controls.
Ischemic stroke is a serious threat to human life and health, which is often accompanied by cerebral ischemia-reperfusion (I/R) injury in clinic. Ischemic postconditioning (IPostC) is a short period of mild non-fatal ischemia in the early stage of cerebral I/R injury. However, there are few reports about the protective effect of IPostC.

Objectives: Previous studies have reached different conclusions regarding an association between apolipoprotein E (APOE) polymorphisms and depression. This meta-analysis was designed to clarify these controversies.
Materials And Methods: Literatures were identified reviewing the national and international databases.
Aim: To evaluate the safety and efficacy of sorafenib plus transarterial chemoembolization (TACE) treatment for intermediate hepatocellular carcinoma (HCC).
Methods: Sixty-seven patients with intermediate-stage [Barcelona Clinic liver cancer stage B (BCLC-B)] HCC who were treated with sorafenib plus TACE or TACE alone between 2009 and 2011 were included in the study. Follow-up was until 2014 or patient death.
Objectives: Scutellarin, a flavonoid extracted from the medicinal herb Erigeron breviscapus Hand-Mazz, protects neurons from damage and inhibits glial activation. Here we examined whether scutellarin may also protect neurons from hypoxia-induced damage.
Materials And Methods: Mice were exposed to hypoxia for 7 days and then administered scutellarin (50 mg/kg/d) or vehicle for 30 days Cognitive impairment in the two groups was assessed using the Morris water maze test, cell proliferation in the hippocampus was compared using 5-bromo-2-deoxyuridine (BrdU) immunohistochemistry, and hippocampal levels of nestin and neuronal class III β-tubulin (Tuj-1) were measured using Western blotting.
Histidine triad nucleotide-binding protein 1 (Hint1) is a haploinsufficient tumor suppressor gene. Its role in cancer cell migration has not been previously speculated. In the current study, we examined the expression of Hint1 in metastatic and non-metastatic lymph nodes of hepatocellular carcinoma (HCC) patients and further elucidated the effect of Hint1 expression on girdin expression and phosphorylation of AKT and ERK1/2 and on the migration of HCC cells in vitro.

However, the mechanism underlying this attenuation remains to be elucidated. It was hypothesized that alterations in microRNA (miRNA) expression in the cerebral cortex and hippocampus of mice following I/R is associated with the functional improvement induced by IPostC.

Since neural stem cells (NSCs) could differentiate into myelin-producing oligodendrocytes, we speculate that scutellarin could also be used to treat multiple sclerosis (MS). In the current study, we examined potential effects of scutellarin using a mouse model of MS.

In the present study, we explored the possible role of miR21 involved in the cognitive improvement following voluntary RW in TBI mice. Firstly, in situ hybridization and quantitative real-time PCR (qRT-PCR) were employed to determine the hippocampal expression and location of miR21 in TBI mice with or without spontaneous RW.

Both of human research and animal studies demonstrate that spontaneous exercise can facilitate neuronal plasticity and improve cognitive function in normal or TBI rodent models. However, the possible mechanisms underlying are still not well known.
