Ischemic stroke is currently the second leading cause of mortality worldwide, with limited treatment options available. As resident immune cells, microglia promptly respond to cerebral ischemic injury, influencing neuroinflammatory damage and neurorepair. Studies suggest that microglia undergo metabolic reprogramming from mitochondrial oxidative phosphorylation to glycolysis in response to ischemia, significantly impacting their function during ischemic stroke.

The cognitive decline associated with chronic metabolic disease diabetes has garnered extensive scrutiny, yet its pathogenesis remains incompletely understood, and the advancement of targeted therapeutics has posed a persistent challenge. Ferroptosis, a novel form of cell death characterized by intracellular lipid peroxidation and iron overload, has recently emerged as a significant factor. Numerous contemporary studies have corroborated that ferroptosis within the neurovascular unit is intimately associated with the onset of diabetes-induced cognitive impairment.

Article Synopsis
  • Diarrheal irritable bowel syndrome (IBS-D) causes diarrhea and stomach pain due to various reasons, and a natural remedy called Sishen Wan (SSW) seems to help, but we don't know exactly how it works.
  • Researchers tested SSW on mice with IBS-D and found it helped their symptoms by improving bowel movements, reducing stomach sensitivity, and promoting mucus production in the intestines.
  • SSW also changed the mix of good bacteria in the gut, making it healthier, by supporting certain processes in the body that help keep the intestines strong.

The interaction of iron and intestinal flora, both of which play crucial roles in many physiologic processes, is involved in the development of Metabolic syndrome (MetS). MetS is a pathologic condition represented by insulin resistance, obesity, dyslipidemia, and hypertension. MetS-related comorbidities including type 2 diabetes mellitus (T2DM), obesity, metabolism-related fatty liver (MAFLD), hypertension polycystic ovary syndrome (PCOS), and so forth.

Background: Shenxiang Suhe Pill (SXSHP), a Chinese medicine formula, is widely used in clinic to treat coronary heart disease (CHD). However, due to the complex composition of SXSHP, its underlying mechanisms and pharmacodynamic properties are still unknown. In this paper, we try to define the compounds of SXSHP by dual-screening the active ingredients with anti-inflammation and antioxidant effects and predict its multi-target-pathway in CHD therapy using network pharmacology.
