Pulsatilla powder (PP), a herbal formulation composed of Pulsatilla, Rhizoma Coptidis, Phellodendron Bark, and Fraxini Cortex, has proven to be an effective treatment for DHD. Although the pentose phosphate pathway (PPP) has been associated with its therapeutic effects, the exact mechanism of action remains unclear. In this study, the DHD model in piglets was established to evaluate clinical symptoms, organ index, serum index, histological changes, colonic metabolites, and molecular mechanisms using techniques such as QPCR, ELISA, WB and metabolomics. PP improved intestinal health by restoring spleen and lung index, increasing LDL-C and HDL-C levels (HDL-C: p &lt; 0.05), decreasing mRNA expression levels of IFN-\u03b3 and TNF-\u03b1 mRNA (p &lt; 0.01), and increasing MUC1 and MUC2 expression. Metabolomics analysis has identified 44 pathways, including pentose phosphate and glutathione pathways, and 132 differential metabolites have involved in DHD treatment. PP significantly reduced G6PD (p &lt; 0.01), inhibited the pentose phosphate pathway, reduced NOX production (p &lt; 0.01), and suppressed ROS production (p &lt; 0.01). These effects alleviated oxidative stress and intestinal damage, demonstrating PP\u2019s effectiveness in treating DHD by targeting critical enzymes and ROS levels.<\/jats:p>","DOI":"10.3390\/vetsci12050403","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T06:10:13Z","timestamp":1745561413000},"page":"403","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Pulsatilla Powder Ameliorates Damp-Heat Diarrhea in Piglets Through the Regulation of Intestinal Mucosal Barrier and the Pentose Phosphate Pathway Involving G6PD and NOX"],"prefix":"10.3390","volume":"12","author":[{"given":"Yunqi","family":"Qu","sequence":"first","affiliation":[{"name":"Department of Traditional Chinese Veterinary Medicine, College of Veterinary Medicine, Southwest University, Chongqing 402460, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0814-1751","authenticated-orcid":false,"given":"Qi","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Veterinary Medicine, College of Veterinary Medicine, Southwest University, Chongqing 402460, China"},{"name":"Institute of Traditional Chinese Veterinary Medicine, Southwest University, Chongqing 402460, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenying","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Veterinary Medicine, College of Veterinary Medicine, Southwest University, Chongqing 402460, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lifang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Veterinary Medicine, College of Veterinary Medicine, Southwest University, Chongqing 402460, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haolian","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Veterinary Medicine, College of Veterinary Medicine, Southwest University, Chongqing 402460, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siyue","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Veterinary Medicine, College of Veterinary Medicine, Southwest University, Chongqing 402460, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"297","DOI":"10.1016\/j.aninu.2024.03.006","article-title":"Nutrition strategies to control post-weaning diarrhea of piglets: From the perspective of feeds","volume":"17","author":"Tang","year":"2024","journal-title":"Anim.
