Background: Previous study confirmed that both TaohongSiwu decoction (THSWD) and improved hypertension-induced endothelial dysfunction. However, the mechanism of THSWD combined with remains unclear.
Purpos: e: We aimed to investigate the microecological mechanism underlying the THSWD combined with for the prevention of hypertensive vascular endothelial dysfunction.
Methods: Eight percent high-salt diet was applied to induce hypertension in a mouse model for 4 weeks. THSWD, and THSWD combined with were used to intervene in the model mice to observe the changes of systolic blood pressure (SBP), body weight, blood routine, endothelial function, gut contents microbiota and bile acid metabolites.
Results: Results revealed that THSWD combined with significantly restored blood pressure and regulated body weight, and markedly downregulating serum and vascular levels of endothelin-1 (ET-1), thrombin regulatory protein (TM), vascular hemophilia factor (vWF) and vascular endothelial growth factor (VEGF), and upregulating nitric oxide (NO) levels compared with the model group. Notably, It altered the diversity and community structure of gut contents microbiota in mice. and was enormously up-regulated at the genus level. Serum bile acid differential metabolites cholic acid and chenodeoxycholic acid were markedly altered. Futhermore, there was a close relationship between and endothelial function indexes in mice.
Conclusion: and play important roles in the prevention of vascular endothelial dysfunction in hypertension during the THSWD combined with .

Background And Aims: Taohong Siwu Decoction (THSWD) is a traditional Chinese herbal prescription that is effective for ischemic stroke, Whether THSWD regulates the CCL2/CCR2 axis and thus reduces the inflammatory response induced by ischemic stroke is not known. The aim of this study was to elucidate the mechanism of action of THSWD in the treatment of ischemic stroke using bioinformatics combined with and experiments.
Methods: R language was used to analyze middle cerebral artery occlusion/reperfusion (MCAO/R) rat transcriptome data and to identify differential gene expression following THSWD treatment.

Article Synopsis
- The study explores the effects of Tao Hong Si Wu Decoction (THSWD) on cognitive impairment specifically related to diabetes-associated cognitive dysfunction (DACD) in rat models.
- THSWD was administered to DACD rats, and measurements showed improvements in memory and learning, as indicated by reduced escape latency in the Morris water maze test, along with decreased markers of neuron damage and better blood sugar and lipid levels.
- The findings suggest that THSWD can enhance cognitive function in DACD by inhibiting advanced glycation end products (AGEs) and related pathways, highlighting the potential clinical use of THSWD in treating cognitive issues linked to diabetes.

Methods: According to the predefined inclusion criteria, we conducted a comprehensive search for randomized controlled trials (RCTs) examining the efficacy of THSWD combined with LMWH or THSWD compared to LMWH in patients with hip fractures or undergoing replacement surgery. The search was performed across multiple databases including China National Knowledge Internet, WanFang, Sinomed, Duxiu, PubMed, Embase, Google Scholar, Cochrane, and Web of Science from their inception until December 2023.
