Objective: To examine the impact of different intestinal microbiota conditions on the absorption of couplet medicines (dried toad skin and radix clematidis) into the bloodstream, and to evaluate the therapeutic effects of drug-containing plasma, produced under different intestinal microbiota conditions, on colorectal cancer HT-29 cells.
Methods: In Experiment I, after the pseudo-sterile rat model was established, intragastric administration was performed. Explore the influence of different states of intestinal bacteria on rat organ coefficients, intestine bacteria, plasma metabolites, and so on. In Experiment II, the HT-29 cells of colon cancer were given to each group of drug-containing plasma for intervention to explore the intervention effect of HT-29-cell plasma produced under the influence of different states of intestinal bacteria.
Results: Pseudo-sterile conditions can affect the body weight, organ coefficients, and immune cell ratios of rats, leading to dysbiosis in various segments of their intestinal microbiota. After administering traditional Chinese medicine under pseudo-sterile conditions, the immune cell ratios in rats returned to normal, and the dysbiosis in the intestinal microbiota improved. There were 271 differential metabolites in the plasma between the groups. Cellular experiments indicate that plasma containing drugs obtained under normal gut microbiota conditions can significantly inhibit the proliferation and migration of HT-29 cells (p < 0.01), while the inhibitory effect of plasma containing drugs obtained under dysbiotic gut microbiota conditions is reduced (p < 0.05).
Conclusion: There is a bidirectional regulatory effect between the gut microbiota and the core medicinal pair. On one hand, dysbiosis weakens the efficacy of the medication. Dysbiosis can affect the blood components of the core medicinal pair. Compared to the drug-containing plasma produced under normal gut microbiota conditions, the drug-containing plasma produced under dysbiosis conditions has a reduced inhibitory effect on the proliferation of HT-29 cells. On the other hand, the drug repairs certain functions of the microbiota. After the drug enters the intestine, it exerts a positive regulatory effect on the dysbiosis of the intestinal microbiota in rats, partially improving the dysbiosis caused by antibiotics, restoring the balance of CD3+, CD4+, and CD8 + ratios in rats, and partially restoring the anticancer activity of drug-containing plasma.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Background: Breast milk represents the optimal feeding strategy for newborns, supporting not only nutrition but also the establishment of a unique microbiota. The bacterial composition and diversity of this microbiota are shaped by various maternal and infant-related factors.
Objectives: This single-center prospective study aimed to examine the breast milk microbiota and determine the maternal and infant-related factors influencing its composition and diversity over the time.

Environmental and nutritional factors are critical in modulating the immune system of Penaeus vannamei, particularly under viral threats such as white spot syndrome virus (WSSV). This study evaluated the effects of two Amazonian plant-based feed additives, buriti (Mauritia flexuosa) and pracaxi (Pentaclethra macroloba) brans, on shrimp immunocompetence, oxidative balance, and resistance to WSSV. Shrimp were fed diets supplemented with 4% or 8% of each ingredient.

Introduction: The increasing use of biodegradable plastics has led to the inevitable human consumption of biodegradable microplastics (MPs). These MPs can be degraded and absorbed into various organs and tissues via the gastrointestinal tract, with the liver being the primary target for digestion and absorption.
Objectives: This study aimed to investigate the toxic effects and mechanisms of biodegradable MPs on the liver following gastrointestinal degradation.

Ethnopharmacological Relevance: Corus officinalis Siebold & Zucc belongs to the genus Cornus in the Cornaceae family, and was first recorded in the "Shennong Herbal Classic", now has been included in "according to the tradition of both food and Chinese herbal medicines", consist of kidney and liver tonifying, antioxidant substances including cycloid glycosides, flavonoids, polyphenols, organic acids, etc. AIM OF THE STUDY: This study was aimed at discovering the mechanism underlying the anti-hyperemia effect of Cor in rats, particularly its protective effect against liver and kidney dysfunction caused by HUA.
Materials And Methods: In this study, the effect of Cor extract against HUA was verified in rats, subsequently, network pharmacology combined with non-targeted metabolomic were performed to investigate its composition characteristics, and further multi-omics studies and molecular validation were performed to reveal molecular mechanism both in vivo and in vitro.
