The Interplay between Mitochondrial Dysfunction and Ferroptosis during Ischemia-Associated Central Nervous System Diseases.

Cerebral ischemia, a leading cause of disability and mortality worldwide, triggers a cascade of molecular and cellular pathologies linked to several central nervous system (CNS) disorders. These disorders primarily encompass ischemic stroke, Alzheimer's disease (AD), Parkinson's disease (PD), epilepsy, and other CNS conditions. Despite substantial progress in understanding and treating the underlying pathological processes in various neurological diseases, there is still a notable absence of effective therapeutic approaches aimed specifically at mitigating the damage caused by these illnesses.

[Effect on Danggui Shaoyao Powder on mitophagy in rat model of Alzheimer's disease based on PINK1-Parkin pathway].

This study investigated the mechanism of Danggui Shaoyao Powder(DSP) against mitophagy in rat model of Alzheimer's disease(AD) induced by streptozotocin(STZ) based on PTEN induced putative kinase 1(PINK1)-Parkin signaling pathway. The AD rat model was established by injecting STZ into the lateral ventricle, and the rats were divided into normal group, model group, DSP low-dose group(12 g·kg~(-1)·d~(-1)), DSP medium-dose group(24 g·kg~(-1)·d~(-1)), and DSP high-dose group(36 g·kg~(-1)·d~(-1)). Morris water maze test was used to detect the learning and memory function of the rats, and transmission electron microscopy and immunofluorescence were employed to detect mitophagy.

[Baicalin inhibits LPS/IFN-γ-induced inflammation via TREM2/TLR4/NF-κB pathway in BV2 cells].

This study investigated the mechanism of baicalin on lipopolysaccharide(LPS)/interferon γ(IFN-γ)-induced inflammatory microglia based on the triggering receptor expressed on myeloid cells 2(TREM2)/Toll-like receptor 4(TLR4)/nuclear factor kappaB(NF-κB) pathway. Specifically, LPS and IFN-γ were used to induce inflammation in mouse microglia BV2 cells. Then the normal group, model group, low-dose(5 μmol·L~(-1)) baicalin group, medium-dose(10 μmol·L~(-1)) baicalin group, high-dose(20 μmol·L~(-1)) baicalin group, and minocycline(10 μmol·L~(-1)) group were designed.

Curcumin Acetylsalicylate Extends the Lifespan of .

Aspirin and curcumin have been reported to be beneficial to anti-aging in a variety of biological models. Here, we synthesized a novel compound, curcumin acetylsalicylate (CA), by combining aspirin and curcumin. We characterized how CA affects the lifespan of () worms.

Heilaohuguosus A-S from the fruits of Kadsura coccinea and their hepatoprotective activity.

Phytochemical investigations on the fresh fruits of Kadsura coccinea (Lem.) A. C.

Extract of Naotaifang, a compound Chinese herbal medicine, protects neuron ferroptosis induced by acute cerebral ischemia in rats.

Objective: Our previous research showed that Naotaifang (a compound traditional Chinese herbal medicine) extract (NTE) has clinically beneficial effects on neurological improvement of patients with acute cerebral ischemia. In this study, we investigated whether NTE protected acute brain injury in rats and whether its effects on ferroptosis could be linked to the dysfunction of glutathione peroxidase 4 (GPX4) and iron metabolism.

Methods: We established an acute brain injury model of middle cerebral artery occlusion (MCAO) in rats, in which we could observe the accumulation of iron in neurons, as detected by Perl's staining.

[Analysis on medication rules for treatment of dementia by ancient physicians based on data mining methods].

To analyze the medication features and regularity of prescriptions of Chinese medicine in treating patients with dementia based on ancient medical records. In the article, we retrieved the ancient medical records related to the treatment of dementia (from the Han Dynasty to the late Qing period) in Chinese Medical Classics, Chinese Ancient Medical Books and digital library, and then set up a medical records normalized database. The medication features and prescription rules for dementia were analyzed by frequency statistics and association rules (Apriori algorithm, improved mutual information algorithm and complex system entropy clustering).

Resolving neuroinflammation, the therapeutic potential of the anti-malaria drug family of artemisinin.

Artemisinin (Qinghaosu) and its semi-synthetic derivatives have been demonstrated to alleviate neuroinflammatory response in the central nerve system (CNS). In this review, we summarized that artemisinins are capable to treat neuroinflammtion-related CNS diseases in both direct (via regulating inflammatory process in the CNS, exerting anti-oxidative stress and neuroprotective effect, and preventing Aβ accumulation) and indirect (via maintaining BBB integrity, suppressing systemic inflammation and alleviating intestinal inflammtion) manner. However, the precise mechanism of their anti-neuroinflammatory effects and potential neurotoxicity, which hindered further progress in these aspects, remains unclear.

Effects of the aqueous extract of the Chinese medicine Danggui-Shaoyao-San on rat pineal melatonin synthesis.

Objectives: The purpose of this study is to investigate if the aqueous extract of the Chinese medicine Danggui-Shaoyao-San (DSS) can increase the plasma level of melatonin and enhance the function of the pineal gland of naturally aged rats.

Methods: The rats were treated with DSS at doses of 3ml or same volume of distilled water by oral administration at 11 p.m.
