[Establishment and evaluation of a premenstrual syndrome rat model induced by progesterone-withdrawal and emotional-stimulation].

Premenstrual syndrome(PMS) lacks a highly consistent and feasible animal model that aligns with diagnostic and therapeutic standards in both traditional Chinese medicine(TCM) and western medicine, resulting in a lack of reliable experimental carriers for studying its pathogenesis and pharmacological effects. This study aims to systematically analyze the biological implications of PMS from the perspective of the "disease-syndrome-symptom" correlation and establish preparation and evaluation methods for an improved animal model of this disease. Firstly, clinical symptom gene sets related to the Qi stagnation syndromes due to liver depression and blood stasis in PMS in both modern medicine and TCM diagnostic standards were collected through GeneCards, DisGeNET, Mala-Cards, and the System of Foundational Diagnostic Association(SoFDA) database, as well as published literature.

Study on the chemical constituents and mechanism of Kai-Xin-San based on UPLC-Q-Exactive MS and network pharmacology.

Ethnopharmacological Relevance: Vascular disease (VD) is a kind of common disease harmful to the health of the middle-aged and elderly, which has the characteristics of long treatment cycle and high recurrence rate, and without effective method to treat so far. Traditional Chinese medicine (TCM) has the characteristics of multi-components and multi-targets to treat diseases. Kai-Xin-San is a TCM formula applied for treating psychiatric diseases such as depression in China for thousands of years, and it has been used in clinical treatment of VD.

Chuanxiong improves angiogenesis via the PI3K/AKT/Ras/MAPK pathway based on network pharmacology and DESI-MSI metabolomics.

Chuanxiong, a traditional Chinese medicine, has been proved to treat a variety of cardiovascular and cerebrovascular diseases by promoting angiogenesis. However, the mechanisms of Chuanxiong's pro-angiogenesis is currently unknown. This study aimed to uncover the effect and mechanisms of Chuanxiong promoting angiogenesis and .

Spatial metabolomics reveal mechanisms of dexamethasone against pediatric pneumonia.

Currently, drugs are limited to treating pediatric pneumonia in clinical practice. It is urgent to find one new precise prevention and control therapy. The dynamically changing biomarkers during the development of pediatric pneumonia could help diagnose this disease, determine its severity, assess the risk of future events, and guide its treatment.

Synthesis and biological activity evaluation of podophyllotoxin-linked bile acid derivatives as potential anti-liver cancer agents.

Podophyllotoxin's undifferentiated cytotoxicity and poor selectivity limit its clinical application. To improve above disadvantages, conjugation of bile acids with podophyllotoxin could improve cell line selectivity of liver cancer to achieve clinical translation further. Enlightened by the bile acids' moiety magic characters, thirty podophyllotoxin-linked bile acid derivatives had been designed and synthesized.

Systems pharmacology and GC-MS metabolomics reveal the efficacy and mechanisms of zedoary oil on acute liver injury induced by oxidative stress.

Background: Zedoray oil (ZO) is the main component of Curcuma zedoaria, one traditional herb used for dispersing stasis clinically in China. Previously, the potential of ZO was discovered against lethal and acute liver injury (ALI) mice with little impact on the immune, which deserved further study.

Methods: An approach combined systems pharmacology with GC-MS metabolomics was applied for predicting pathways affected by ZO.

Synergistic Combination of Facile Thiol-Maleimide Derivatization and Supramolecular Solvent-Based Microextraction for UHPLC-HRMS Analysis of Glutathione in Biofluids.

Glutathione (GSH) is the most abundant non-protein thiol in biofluids, enabling diverse physiological functions. Among the proposed methods for GSH detection, ultra-high-performance liquid chromatography (UHPLC) coupled with high-resolution mass spectrometry (HRMS) has the advantages of high sensitivity and efficiency. In this study, a novel analytical method was developed for the determination of GSH using supramolecular solvent (SUPRAS)-based dispersive liquid-liquid microextraction (DLLME) and UHPLC-HRMS.

Tetrahydropalmatine triggers angiogenesis via regulation of arginine biosynthesis.

Over a short span of two decades, the central role of angiogenesis in the treatment of wound healing, diverse cancers, nerve defect, vascular injury and several ophthalmic diseases has become evident. Tetrahydropalmatine, as the index component of Corydalis yanhusuo W. T.
