Article Abstract
The project was launched to analyze the effects of sulfur-fumigated Ophiopogonis Radix on endogenous metabolites in rats by metabonomics. The preparation method of sulfur-fumigated Ophiopogonis Radix in laboratory was established. Then the blood samples of SD rats in blank group,Ophiopogonis Radix extract group and sulfur-fumigated Ophiopogonis Radix extract group were investigated by UHPLC-Q-Exactive. The differential metabolites were screened and identified by PCA(principal component analysis),OPLSDA(orthogonal partial least squares discriminant analysis) and variable importance projection(VIP),and the metabolic pathways were analyzed. Finally,a total of 15 potential biomarkers were identified. Compared with the samples of Ophiopogonis Radix extract group,sulfur-fumigated Ophiopogonis Radix mainly affected the biosynthesis and metabolism of amino acids in normal rats. Its mechanism may be related to the biosynthesis of phenylalanine,tyrosine,tryptophan and aminoacyl-tRNA as well as the metabolism of phenylalanine and tryptophan. Based on UHPLC-HRMS metabonomics,this paper discussed the effects of sulfur-fumigated Ophiopogonis Radix on endogenous metabolites in rats,which provided an idea for the metabolic study of other sulfur-fumigated traditional Chinese medicines.

Background: Colorectal cancer, being 1 of the most significant malignant tumors globally, poses a substantial risk to human health. Unfortunately, its 5-year survival rate stands at a mere 65%. There remains an urgent need for the development of novel treatments to combat this detrimental malignancy effectively.

Shengmai San (SMS) is a traditional Chinese medicine formula used for supplementing and and can mitigate symptoms related to malignant arrhythmia and heart failure. This systematic review aimed at exploring the effectiveness and safety of SMS for viral myocarditis (VMC). Eight databases from their inception to June 2023 were searched to identified randomized controlled trials (RCTs) focusing on SMS for VMC.

Ophiopogonis Radix, a well-known Chinese herb, is dominantly cultivated in Zhejiang and Sichuan provinces, with the Zhejiang Ophiopogonis Radix acting as one of the eight Zhejiang-based traditional medical materials. Phytochemical studies have shown that Ophiopogonis Radix is rich in steroidal saponins, homoisoflavonoids, terpenoids, and polysaccharides, which collectively confer it with cardiovascular protection, anti-inflammation, anticancer, antioxidation, and immune regulation activities. Studies also show that Ophiopogonis Radix originated from Zhejiang and Sichuan is discriminated in both chemical components and clinical efficacy, while the existing reviews of Ophiopogonis Radix appear to pose a particular focus on Sichuan species, but not for Zhejiang origin.

This study examines the therapeutic effects of Shengmai Powder (SMP) on both in vitro and in vivo models of chronic obstructive pulmonary disease (COPD) and the underlying mechanisms. Cigarette smoke and cigarette extracts were used to create in vitro and in vivo models of COPD. ELISA was used to measure the levels of pro-inflammatory factors (IL-6, TNF-α, and IL-1β) in mouse lung tissue and alveolar macrophages.
