Background: Hemorrhage lesions may lead to bilateral hypertrophic olivary degeneration (HOD) through interruption of the dentato-rubral-olivary pathway. The pathological features of HOD are unusual neuronal trans-synaptic degenerative changes.
Case Summary: A 56-year-old female was admitted to our hospital because her lower extremities and left upper ones were unable to move for 3 mo, and the swelling of her right lower extremities became worse 3 days ago. She had a hypertension history. Her characteristic clinical manifestations are palatal myoclonus and nystagmus. The patient's magnetic resonance imaging (MRI) results showed that she had bilateral HOD after an acute pontine hemorrhage. She was given symptomatic and supportive treatment. The gabapentin, the memantine and the trihexyphenidyl were taken twice a day each. The rehabilitation and psychotherapy were implemented. After 3 months of treatment, her eye symptoms improved.
Conclusion: Bilateral HOD is a rare phenomenon after pontine hemorrhage. The key to diagnosis lies in the clinical manifestations and MRI results.

Stroke is the second leading cause of death worldwide, according to the latest report by the World Health Organization (WHO). Intracerebral hemorrhage comprises 20-25% of the stroke in the young, with incidence rates of three to six in 100,000 people per year. One of the most common and important causes of hemorrhagic stroke in the general population is hypertension.

Rationale: Cerebellar pontine angle lipomas with trigeminal neuralgia are rare. The treatment choice is influenced by whether the pain is caused by the lipoma or the compression of blood vessels. Herein, we aimed to report a case of the disease and provide a reference for its treatment.

Increased pro-SFTPB in HDL promotes the pro-inflammatory transition of HDL and represents a sign of poor prognosis in ARDS patients.

Background: Acute respiratory distress syndrome (ARDS) is causatively associated with excessive alveolar inflammation involving deregulated pro-inflammatory macrophage polarization. High-density lipoprotein (HDL) showed critical anti-inflammatory roles by modulating macrophage function, and its adverse transition to pro-inflammation has an important role in the pathogenesis of ARDS. However, the relationship between HDL protein constituents and functional remodeling is unknown in ARDS.

Background: Traumatic injury leads to gut dysbiosis with changes in microbiome diversity and conversion toward a "pathobiome" signature characterized by a selective overabundance of pathogenic bacteria. The use of non-selective beta antagonism in trauma patients has been established as a useful adjunct to reduce systemic inflammation. We sought to investigate whether beta-adrenergic blockade following trauma would prevent the conversion of microbiome to a "pathobiome" phenotype.
