Huashi baidu granule alleviates inflammation and lung edema by suppressing the NLRP3/caspase-1/GSDMD-N pathway and promoting fluid clearance in a porcine reproductive and respiratory syndrome (PRRS) model.

Ethnopharmacological Relevance: Huashi Baidu Granule (HSBDG), a traditional Chinese medicine (TCM), is used for treating coronavirus disease 2019 (COVID-19). Porcine reproductive and respiratory syndrome (PRRS) is considered the "COVID-19" for swine. According to the TCM theory, "dampness" is the main pathogenic factor in COVID-19 and PRRS, and "Huashi" means that this formula is good at removing "dampness".

[Synergistic effect of Coptidis Rhizoma processed with Euodiae Fructus on ulcerative colitis through energy metabolism].

Based on the differences in targeted energy metabolomics, intestinal barrier protein expression, and glucose transport,the synergistic mechanism of Coptidis Rhizoma(CR) processed with Euodiae Fructus(ECR) on ulcerative colitis(UC) was explored.Mice were administered 4% dextran sulfate sodium to induce UC model, and then randomly divided into a model group, a CR group,and an ECR group. After 14 days of treatment, the therapeutic effect of processing on UC was assessed through histopathology of colon tissue and inflammatory indexes.

[Excretion of three alkaloids from Simiao Pills in urine, feces, and bile between normal and type 2 diabetic rats].

This study investigated the differences in excretion kinetics of three alkaloids and their four metabolites from Simiao Pills in normal and type 2 diabetic rats. The diabetes model was established in rats by injection of streptozotocin, and the alkaloids in urine, feces, and bile of normal and diabetic rats were detected by LC-MS/MS to explore the effect of diabetes on alkaloid excretion of Simiao Pills. The results showed that 72 h after intragastric administration of the extract of Simiao Pills, feces were the main excretion route of alkaloids from Simiao Pills.

Coptidis Rhizoma processed with Evodia Rutaecarpa improves the effect on ulcerative colitis by increasing intestinal energy metabolites alpha-ketoglutarate and Lactobacillus reuteri.

Background: Evodia Rutaecarpa-processed Coptidis Rhizoma (ECR) is a traditional Chinese medicine for the treatment of ulcerative colitis (UC) in China. However, the mechanisms underlying the ECR processing are not elucidated.

Purpose: Coptidis Rhizoma (CR) regulates the gut microbiota in the treatment of gastrointestinal diseases.

Simiao Wan and its ingredients alleviate type 2 diabetes mellitus IRS1/AKT2/FOXO1/GLUT2 signaling.

Background: Type 2 diabetes mellitus (T2DM) is a metabolic disease. Simiao Wan (SMW) is a commonly used clinical drug for hyperuricemia treatment. SMW has been confirmed to improve insulin resistance and is expected to be a novel hypoglycemic agent.

Network Pharmacology Integrated with Transcriptomics Analysis Reveals Ermiao Wan Alleviates Atopic Dermatitis via Suppressing MAPK and Activating the EGFR/AKT Signaling.

Background: Ermiao Wan (EMW) is commonly used to treat atopic dermatitis (AD) in China. However, the pharmacological mechanisms underlying the action of EMW against AD remain unclear.

Purpose: We aimed to determine the mechanisms underlying the effectiveness of EMW in the treatment of AD.

Xianglian pill modulates gut microbial production of succinate and induces regulatory T cells to alleviate ulcerative colitis in rats.

Ethnopharmacological Relevance: Xianglian pill (XLP), a traditional Chinese formula, is widely used as treatment for ulcerative colitis (UC) in China. However, the mechanism of its therapeutic effect is still unclear.

Aim Of The Study: Our previous studies showed a low oral bioavailability and a predominant distribution of major XLP ingredients in the gut.

[Comparative analysis of pharmacokinetics and intestinal absorption of six alkaloids between Sanmiao Pills and Simiao Pills in rats].

The present study investigated the differences in pharmacokinetics and intestinal absorption of six alkaloids in Sanmiao Pills and Simiao Pills in rats and explored the different efficacies of the two formulae. After oral administration of Sanmiao Pills and Simiao Pills in rats, blood samples were collected at different time points. Samples were prepared for the determination of six alkaloids in plasma by UPLC-MS/MS.

Coix seed polysaccharides alleviate type 2 diabetes mellitus via gut microbiota-derived short-chain fatty acids activation of IGF1/PI3K/AKT signaling.

Type 2 diabetes mellitus (T2DM) has become a worldwide concern in recent years. Coix seed (CS) as a homologous substance of traditional Chinese medicine and food, its polysaccharides can improve the symptoms of patients with metabolic disorders. Since most plant polysaccharides are difficult to digest and absorb, we hypothesized that Coix seed polysaccharides (CSP) exert hypoglycemic effects through the gut.

Comparative pharmacokinetics, intestinal absorption and urinary excretion of six alkaloids from herb pair Phellodendri Chinensis cortex-Atractylodis Rhizoma.

Phellodendri Chinensis Cortex (PCC) and Atractylodis Rhizoma (AR) are frequently used as herb pair to treat eczema and gout owing to their synergistic effects. Alkaloids are the major ingredients from PCC and the effect of their combination on the in vivo processing of alkaloids remains unclear. In this study, a simple and reliable UPLC-MS/MS method for simultaneous determination of six alkaloids in rat plasma was developed.

Network pharmacology and pharmacokinetics integrated strategy to investigate the pharmacological mechanism of Xianglian pill on ulcerative colitis.

Background: Ulcerative colitis (UC) is a chronic inflammatory bowel disease with high morbidity, which leads to poor quality of life. The Xianglian pill (XLP) is a classical Chinese patent medicine and has been clinically proven to be an effective treatment for UC.

Purpose: The pharmacological mechanism of the key bioactive ingredients of XLP for the treatment of UC was investigated by a network pharmacology and pharmacokinetics integrated strategy.
