Berberine, palmatine, physcion, rhein, calycosin-7-O-glucoside, and ferulic acid are six major active consituents that are present in Gushen Jiedu capsule (GSJD) extracts. The aim of this study was to determine the pharmacokinetics of the six active consituents in vivo by a rapid, sensitive, and precise UPLC-MS/MS method, which were compared between normal and diabetic nephropathy (DN) rats. Good separation of the target analytes and internal standards (ketoprofen and puerarin) was obtained on a Waters BEH C UPLC column with a mobile phase of 0.

Rapid and simple monitoring of vancomycin (VAN) concentration in blood is a vital strategy for maximizing therapeutic efficacy, minimizing toxicity and developing a personalized treatment plan. In this work, a simple multicolor immunosensor is proposed to enable rapid monitoring of VAN concentration in serum, without using any expensive and bulky instrument. The multicolor immunosensor platform is a system that works based on the principle that the product of cetyltrimethylammonium bromide-blue oxide of 3,3',5,5'-tetramethylbenzidine interaction (CTAB/TMB) and TMB increases simultaneously with the decrease in VAN concentration, whereas AuNBPs are insensitive to VAN.

Ferroptosis, a form of regulated cell death, has been widely explored as a novel target for the treatment of diseases. The failure of the antioxidant system can induce ferroptosis. Epigallocatechin-3-Gallate (EGCG) is a natural antioxidant in tea; however, whether EGCG can regulate ferroptosis in the treatment of liver oxidative damage, as well as the exact molecular mechanism, is unknown.

Medulloblastoma is a malignancy of the central nervous system that occurs most frequently in childhood and is often difficult to diagnose due to its similarities to conventional imaging findings for other pediatric intracranial tumors such as astrocytomas and ependymomas. The purpose of this study was to identify new metabolites and differential metabolic pathways by analyzing the significantly different metabolites present in the plasma of children with medulloblastoma in comparison with those with other intracranial tumors. Plasma was collected from 37 children with medulloblastoma and 34 children with other intracranial tumors.

The effect of intestinal flora changes on the pharmacokinetics of astragaloside Ⅳ in rats with type 2 diabetes mellitus was explored in this study. The rat model in preliminary experiment was established by high-sugar and high-fat diet combined with the intraperitoneal injection of low-dose streptozotocin(STZ). Rats were divided into model group, astragaloside Ⅳ group, berberine group and combination group(five rats in each group).

Matrine (MT) is a naturally occurring alkaloid and an bioactive component of Chinese herbs, such as and Radix . Emerging evidence suggests that MT possesses anti-cancer, anti-inflammatory, anti-oxidant, antiviral, antimicrobial, anti-fibrotic, anti-allergic, antinociceptive, hepatoprotective, cardioprotective, and neuroprotective properties. These pharmacological properties form the foundation for its application in the treatment of various diseases, such as multiple types of cancers, hepatitis, skin diseases, allergic asthma, diabetic cardiomyopathy, pain, Alzheimer's disease (AD), Parkinson's disease (PD), and central nervous system (CNS) inflammation.

Owing to the potential health benefits, anthocyanin-rich teas (Camellia sinensis) have attracted interest over the past decade. Previously, we developed the cultivar 'Ziyan,' which has dark-purple leaves because of the accumulation of a high amount of anthocyanins. In this study, we performed a genetic analysis of this anthocyanin-rich tea cultivar and 176 of its naturally pollinated offspring.

Sustained-release preparation is a hot spot in antitumor drug research, where the first task is to select suitable drug carriers. Research has revealed that carboxylic acid iron metal⁻organic frameworks (MOFs), constructed from iron (Fe) ions and terephthalic acid, are nontoxic and biocompatible. Due to the breathing effect, the skeleton of this mesoporous material is flexible and can reversibly adapt its pore size through drug adsorption.
