Acute lung injury (ALI) is a common clinical condition that badly influences people’s health. Recent studies indicated that Aster tataricus (RA) had potential effects on ALI, but the effective components and their mechanism is not clear. In this study, we found that the Fraction-75 eluted from RA extract could significantly protect the lipopolysaccharide (LPS)-induced ALI in mice, including alleviating the severity of lung pathology, attenuating the pulmonary edema, and reducing the release of inflammatory cells. Further ingredient analyses demonstrated that there were mainly 16 components in it, among which 10 components were collected according to their relative peak area and oral bioavailability. Next, the components-disease targets network suggested that the candidate components had extensive associations with 49 known therapeutic targets of ALI, among which 31 targets could be regulated by more than one component. Herein, GO functional and pathway analysis revealed that the common targets were associated with four biological processes, including the inflammatory response to stimulus, cellular process, chemokine biosynthetic process and immune system process. Furthermore, the ELISA validation indicated that the candidate components in RA extract may protect the LPS-induced ALI mainly through inhibiting the release of inflammatory cytokines and promoting the repair of vascular endothelial.

The dried root and rhizome of Aster tataricus (RA), is a traditional Chinese medicine has been used for more than 2000 years with the function of antitussive, expectorant and antiasthmatic. Ancient books and modern pharmacological researches demonstrated that RA may have the function of moistening intestines and relieving constipation, but there was a lack of systematic evidence. The aim of this study was to comprehensively evaluate the efficacy and possible mechanisms of ethanol extract of Aster tataricus (ATE) in treating constipation from in vivo to in vitro. In vivo, the ATE was studied in loperamide-induced constipation of mice. In vitro, different concentrations of ATE was tested separately or cumulatively on spontaneous and agonists-induced contractions of isolated rat duodenum strips. In vivo, at doses of 0.16, 0.8 g/mL, ATE showed significantly promotion of the small intestinal charcoal transit, decrease of the amount of remnant fecal, and increase of the content of fecal water in colon. In addition, ATE could effectively relieve colonic pathological damage caused by loperamide as well. In vitro, with the cumulative concentration increase of ATE from 0.8 to 6.4 mg/mL, it could significantly decrease the contraction caused by KCl or Ach, and gradually restore to near base tension value.Meanwhile, it could also partially but significantly inhibit the contractions induced by Ach and CaCl₂ on rat duodenum in a concentration related manner. Taking all these findings together, it could be speculated that ATE may attenuate constipation mainly through antagonizing the binding of acetylcholine to muscarinic receptor, inhibiting Ca²⁺ influx and anti-inflammation.

Anthocyanins from red cabbage are of great importance for their applications in the food industry as natural colorants and their beneficial effects on human wellness as natural antioxidants. This study aimed to develop an effective method for the isolation of anthocyanins with the help of a combination of alternate recycling and direct recycling preparative liquid chromatography. Ten major components of anthocyanins from red cabbage were isolated and their structures were identified by HPLC-MS/MS. Meanwhile, the stability of the isolated anthocyanins under various light conditions was also investigated so as to provide data for their storage. In sum, the results showed that twin column recycling preparative chromatography is an effective method for the isolation of anthocyanin monomers with similar structures. Besides, the stability of various anthocyanins from red cabbage was related to the number of acylated groups and mainly affected by illumination.

Background: Chronic heart failure (CHF) is a common clinical syndrome characterized by reduced exercise capacity, diminished quality of life (QoL), and unfavorable cardiovascular outcomes. Conventional cardiac rehabilitation often requires moderate-to-high-intensity exercise, which may be tolerated poorly by many CHF patients. Low-intensity mind–body interventions, such as traditional Chinese exercises (TCEs), are potentially more suitable; however, the evidence from existing studies is fragmented and sometimes inconsistent. Thus, this study aimed to conduct an umbrella review of systematic reviews (SRs) and meta-analyses (MAs) to evaluate the effectiveness of TCEs in improving exercise capacity, QoL, and cardiovascular function in patients with CHF. Methods: An umbrella review of SRs/MAs was conducted by searching English and Chinese databases without language limits and focusing on randomized controlled trials (RCTs) that assessed the additional benefit of TCEs in individuals with CHF. Methodological quality was appraised using the A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) checklist and the Risk of Bias in Systematic Reviews (ROBIS) instrument. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was utilized to quantify the certainty of evidence. Individual trial data were retrieved, and re-meta-analyses were performed using standard statistical procedures, with publication bias assessed via Egger's test. Results: A total of 15 SRs/MAs were included, encompassing 65 original trials. Our re-meta-analysis indicated that TCEs were associated with substantially longer 6-minute walk test (6-MWT) values, improved QoL measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ), higher left ventricular ejection fraction (LVEF), reduced B-type natriuretic peptide (BNP) levels, and enhanced maximal oxygen consumption (VO2max). Baduanjin exhibited a particularly robust effect on lowering N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations, while Yijinjing yielded comparatively greater improvements in VO2max. Nonetheless, limitations such as suboptimal methodological quality and overlapping study samples require cautious interpretation. Conclusions: TCEs may serve as a beneficial adjunct to standard care for CHF, improving exercise capacity, QoL, and key cardiac markers. Large, rigorous RCTs with extended follow-up are needed to confirm the durability of TCEs and further define the role of these exercises in comprehensive CHF rehabilitation.
