Article Synopsis
  • Xuefu Zhuyu decoction (XFZYD) is traditionally used to treat traumatic brain injury (TBI), but its active ingredients and mechanisms were previously unclear.
  • This study outlines a three-step methodology to identify the bioactive compounds in XFZYD and their pharmacological effects, including metabolomics analysis, ingredient screening, and in vivo validation of the top compound.
  • The results indicated that hydroxysafflor yellow A (HSYA) significantly improved neurological functions and reduced neuronal damage in TBI mice by enhancing blood vessel activity.

Ethnopharmacological Relevance: The repairment of myelin sheaths is crucial for mitigating neurological impairments of intracerebral hemorrhage (ICH). However, the current research on remyelination processes in ICH remains limited. A representative traditional Chinese medicine, Buyang Huanwu decoction (BYHWD), shows a promising therapeutic strategy for ICH treatment.

Article Synopsis
  • * In a study using a mouse model, mice were divided into sham, OA, and calycosin treatment groups; results showed that calycosin significantly increased cartilage synthesis markers and decreased markers indicating cartilage damage.
  • * The findings also involved network pharmacology and molecular docking to confirm that calycosin treatment likely improved cartilage damage by restoring the balance between cartilage synthesis and degradation.

Ethnopharmacological Relevance: Buyang Huanwu Decoction (BYHWD), as a traditional Chinese medical prescription, has been used to treat intracerebral hemorrhage (ICH) for hundreds of years, but the antiapoptotic properties have not yet been studied.

Aim Of The Study: This study aims to elucidate the antiapoptotic mechanism of BYHWD in ICH.

Materials And Methods: The therapeutic effect of BYHWD on ICH was assessed by modified neurological severity scores (mNSS), foot fault, and histopathological staining.

Context: Hydroxysafflor yellow A (HSYA) is the main bioactive ingredient of safflower ( L., [Asteraceae]) for traumatic brain injury (TBI) treatment.

Objective: To explore the therapeutic effects and underlying mechanisms of HSYA on post-TBI neurogenesis and axon regeneration.

A series of polyethyleneimine (PEI) incorporated MIL-101 adsorbents with different PEI loadings were reported for the first time in the present work. Although the surface area and pore volume of MIL-101 decreased significantly after loading PEI, all the resulting composites exhibited dramatically enhanced CO2 adsorption capacity at low pressures. At 100 wt% PEI loading, the CO2 adsorption capacity at 0.
