Toward Understanding Non-coding RNA Roles in Intracranial Aneurysms and Subarachnoid Hemorrhage.

Subarachnoid hemorrhage (SAH) is a common and frequently life-threatening cerebrovascular disease, which is mostly related with a ruptured intracranial aneurysm. Its complications include rebleeding, early brain injury, cerebral vasospasm, delayed cerebral ischemia, chronic hydrocephalus, and also non neurological problems. Non-coding RNAs (ncRNAs), comprising of microRNAs (miRNAs), small interfering RNAs (siRNAs) and long non-coding RNAs (lncRNAs), play an important role in intracranial aneurysms and SAH.

miRNA profiling in autism spectrum disorder in China.

Autism spectrum disorder (ASD) is a clinically complex and heterogeneous disorder. It is characterized by impaired social abilities, disordered language, isolated areas of interest, and repetitive behaviors. Evidence suggested that the neuropathology of ASD is widely distributed, involving epigenetic regulation in the brain.

Hepatic encephalopathy coexists with acquired chronic hepatocerebral degeneration.

Hyperkinetic extrapyramidal syndrome is the typical clinical characteristic of acquired hepatocerebral degeneration (AHD), but is usually not observed with hepatic encephalopathy (HE). We present a case of AHD coexisting with HE. Both conditions were secondary to liver cirrhosis and hepatitis C virus infection.
