With increasing life expectancy， neurodegenerative diseases have become one of the leading causes of ill-health in the elderly. Preventive strategies include following healthy diets， such as the Mediterranean diet， which is particularly rich in polyphenols， bioactive compounds with neuroprotective properties. The aim of this study was to assess the association of microbial phenolic metabolites (MPM) with cognition. This cross-sectional analysis was performed with 200 participants of the PREDIMED trial (Barcelona-Clinic recruitment center). A novel method based on liquid chromatography coupled to mass spectrometry was used to identify urinary MPM (protocatechuic acid， enterodiol glucuronide， enterolactone glucuronide， urolithin B glucuronide， and vanillic acid glucuronide)， and cognitive function was evaluated with neuropsychological tests. Multivariable-adjusted ordinary least squares regression was used to assess the associations between cognitive function and MPM， and a score was calculated as the weighted sum of MPM. A higher MPM score was associated with better frontal lobe function. Among individual metabolites， vanillic acid glucuronide was correlated with frontal cognitive performance. Participants with higher concentrations of vanillic acid glucuronide and urolithin B glucuronide obtained better scores in the Color Trail Test part 2. A higher score for urinary multi-MPM was associated with better frontal cognitive performance in an older Mediterranean population.

Objective: Pharmacopoeias regulate the manufacture of potentised pharmaceutical preparations used in different branches of complementary and integrative medicine.

Empowering sonic hedgehog to rescue brain cells after ischemic stroke

Neural Regeneration Research 2015年第3期10卷 360-362页

作者： olga v.Chechneva Wenbin Deng Department of Biochemistry and Molecular Medicine University of California Institute for Pediatric Regenerative Medicine Shriners Hospitals for Children

Ischemic stroke occurs when blood supply to the brain is interrupted. This can cause irreversible injury to the cen- tral nervous system （CNS） tissue. Each year in the United States almost 800,000 people experience a new or recur- rent stroke. 15% of stroke patients die shortly after insult and only 10% recover completely, leaving the majority of surviving stroke patients with disabilities. Tissue-type plasminogen activator （tPA） is the only available therapy for stroke but its clinical use is limited because of associ- ated danger of intracranial hemorrhage. Therefore, there is an emergent need for stroke therapeutics that are safe and effective when administered at a later time point after insult.
