[Protective effect of Tripterygium glycosides on ulcerative colitis rats based on ERK/p38 MAPK signaling pathway].

This study explored the effect of Tripterygium glycosides(TG) on ulcerative colitis in rats and examined the regulatory role of the extracellular signal-regulated kinase/p38 mitogen-activated protein kinase(ERK/p38 MAPK) signaling pathway. Seventy male Wistar rats were selected and randomly divided into control, model, low-dose TG, medium-dose TG, high-dose TG, positive control, and pathway inhibitor groups. The disease activity index(DAI) score, macroscopic damage score, and microscopic colonic injury score were observed in each group.

[Mechanism of Puerariae Thomsonii Radix in treatment of mild dyslipidemia: based on clinical metabolomics and proteomics].

This study aims to explore the potential metabolic pathways and targets of Puerariae Thomsonii Radix in the clinical treatment of mild dyslipidemia. UPLC-Q-TOF-MS and EASY-nLC-timsTOF-Pro2 were employed to perform metabolomic and proteomic analyses of the plasma samples collected from the patients with mild dyslipidemia at baseline and after 12 weeks of treatment with Puerariae Thomsonii Radix. The multivariate statistical analysis was carried out for comparison between groups, and the correlation analysis was performed for the metabolites and proteins closely related to mild dyslipidemia with the blood lipid indexes.

[Effects of maltodextrin on water adsorption and thermodynamic properties of Codonopsis Radix spray-dried powder].

This study aims to reveal the effects of maltodextrin(MD) on the water adsorption and thermodynamic properties of Codonopsis Radix(DS) spray-dried powder by determining the moisture and energy changes of the powder in the process of moisture absorption. The static weighing method was used to obtain the isothermal water adsorption data of the spray-dried powder in 6 saturated salt solutions(KAc, MgCl_2·6H_2O, K_2CO_3, NaBr, NaCl, and KCl) at 3 temperatures(25, 35, and 45 ℃). Six models were used for fitting of the water adsorption process, and the most suitable model was selected based on the model performance.

Correction: Nitric oxide/paclitaxel micelles enhance anti-liver cancer effects and paclitaxel sensitivity by inducing ferroptosis, endoplasmic reticulum stress and pyroptosis.

[This corrects the article DOI: 10.1039/D3RA04861F.].

Nitric oxide/paclitaxel micelles enhance anti-liver cancer effects and paclitaxel sensitivity by inducing ferroptosis, endoplasmic reticulum stress and pyroptosis.

The objective of this study was to investigate the anticancer activities of biodegradable polymeric micelles composed of monomethoxy poly(ethylene glycol), polylactic acid, and nitric oxide (mPEG-PLA-NO) loaded with paclitaxel (PTX) as a nanomedicine delivery system. We aimed to compare the anticancer effects of these NO/PTX micelles with PTX alone and elucidate their mechanism of action. We evaluated the impact of NO/PTX and PTX on cell viability using Cell Counting Kit-8 (CCK8) assays conducted on the Bel-7402 liver cancer cell line.

[Bletilla striata polysaccharide improves toxic and side effects induced by 5-FU: an untargeted metabolomics study].

This study aimed to analyze the effect of Bletilla striata polysaccharide(BSP) on endogenous metabolites in serum of tumor-bearing mice treated with 5-fluorouracil(5-FU) by untargeted metabolomics techniques and explore the mechanism of BSP in alleviating the toxic and side effects induced by 5-FU. Male BALB/C mice were randomly divided into a normal group, a model group, a 5-FU group, and a 5-FU + BSP group, with eight mice in each group. Mouse colon cancer cells(CT26) were transplanted into the mice except for those in the normal group to construct the tumor-bearing mouse model by subcutaneous injection, and 5-FU chemotherapy and BSP treatment were carried out from the second day of modeling.

[Effect of Zhenwu Decoction on electrical remodeling of cardiomyocytes in heart failure via I_(to)/Kv channels].

This study aimed to investigate the underlying mechanism of Zhenwu Decoction in the treatment of heart failure by regulating electrical remodeling through the transient outward potassium current(I_(to))/voltage-gated potassium(Kv) channels. Five normal SD rats were intragastrically administered with Zhenwu Decoction granules to prepare drug-containing serum, and another seven normal SD rats received an equal amount of distilled water to prepare blank serum. H9c2 cardiomyocytes underwent conventional passage and were treated with angiotensin Ⅱ(AngⅡ) for 24 h.

[Anemoside B4 regulates fatty acid metabolism reprogramming in mice with colitis-associated cancer].

The study aimed to investigate the effect of anemoside B4(B4) on fatty acid metabolism in mice with colitis-associated cancer(CAC). The CAC model was established by azoxymethane(AOM)/dextran sodium sulfate(DSS) in mice. Mice were randomly divided into a normal group, a model group, and low-, medium-, and high-dose anemoside B4 groups.

[Slicing specifications in general rule of processing in Chinese Pharmacopoeia from slicing development of Chinese materia medica processed product and thinking and suggestion on slicing techniques].

Slicing is critical in the processing of Chinese materia medica(CMM) processed product and the specification(thickness) is closely related to the quality of the decoction. On the basis of clarifying the concept and evolution of slicing of CMM processed product by reviewing the Chinese herbal classics of the past dynasties and general rules of local processing standards, this study discussed the development history of slicing specifications in general rules of Chinese Pharmacopoeia(2020 edition), analyzed the current situation and key problems, and proposed the thinking and suggestion on promoting the sound development of slicing of CMM processed product. Since 2000, the slicing thickness of CMM processed product in the general rules of local CMM processed product processing specifications newly revised and issued by 27 provinces, autonomous regions, and municipalities has been consistent with that in the general rules of the Chinese Pharmacopoeia(2020 edition).

[Comparative analysis of powder and piece decocting processes of Yinqiao Powder based on determination of multiple primary components].

The present study established specific chromatograms and a method for determining multiple primary components in Yinqiao Powder decoctions and compared the change rules of chemical composition in powder and piece decocting processes of Yinqiao Powder to provide a scientific basis for the modern research of preparations of Yinqiao Powder. Powder and piece decoctions of Yinqiao Powder were prepared. The specific chromatograms were determined and the content of 17 primary components was measured by high-performance liquid chromatography(HPLC), including adoxosidic acid, neochlorogenic acid, forsythoside E, loganic acid, chlorogenic acid, cryptochlorogenic acid, sweroside, forsythoside Ⅰ, forsythoside H, forsythoside A, isochlorogenic acid B, E-aldosecologanin, hesperidin, phillyrin, arctiin, liquiritigenin, and dipotassium glycyrrhizinate.
