Antioxidant and anti-inflammatory function of Eupatorium adenophora Spreng leaves (EASL) on human intestinal Caco-2 cells treated with tert-butyl hydroperoxide.

Chronic non-communicable diseases (CNCDs) pose a significant public health challenge. Addressing this issue, there has been a notable breakthrough in the prevention and mitigation of NCDs through the use of antioxidants and anti-inflammatory agents. In this study, we aim to explore the effectiveness of Eupatorium adenophora Spreng leaves (EASL) as an antioxidant and anti-inflammatory agent, and its potential applications. To construct a cellular model of oxidative damage and inflammation, Caco-2 cells were treated with tert-butyl hydroperoxide (t-BHP). The biocompatibility of EASL-AE with Caco-2 cells was assessed using the MTT assay, while compatibility was further verified by measuring LDH release and the protective effect against oxidative damage was also assessed using the MTT assay. Additionally, we measured intracellular oxidative stress indicators such as ROS and 8-OHdG, as well as inflammatory pathway signalling protein NFκB and inflammatory factors TNF-α and IL-1ß using ELISA, to evaluate the antioxidant and anti-inflammatory capacity of EASL-AE. The scavenging capacity of EASL-AE against free radicals was determined through the DPPH Assay and ABTS Assay. Furthermore, we measured the total phenolic, total flavonoid, and total polysaccharide contents using common chemical methods. The chemical composition of EASL-AE was analyzed using the LC-MS/MS technique. Our findings demonstrate that EASL-AE is biocompatible with Caco-2 cells and non-toxic at experimental levels. Moreover, EASL-AE exhibits a significant protective effect on Caco-2 cells subjected to oxidative damage. The antioxidant effect of EASL-AE involves the scavenging of intracellular ROS, while its anti-inflammatory effect is achieved by down-regulation of the NFκB pathway. Which in turn reduces the release of inflammatory factors TNF-α and IL-1ß. Through LC-MS/MS analysis, we identified 222 compounds in EASL-AE, among which gentianic acid, procaine and L-tyrosine were the compounds with high antioxidant capacity and may be the effective constituent for EASL-AE with antioxidant activity. These results suggest that EASL-AE is a natural and high-quality antioxidant and anti-inflammatory biomaterial that warrants further investigation. It holds great potential for applications in healthcare and other related fields.

Antioxidant, anti-inflammatory, and anticancer function of Engleromyces goetzei Henn aqueous extract on human intestinal Caco-2 cells treated with t-BHP.

High body mass index (high BMI, obesity) is a serious public health problem, and "obesity-induced oxidative stress, inflammation, and cancer" have become modern epidemic diseases. We carried out this study to explore a functional beverage that may protect against obesity-induced diseases. The Engleromyces goetzei Henn herbal tea is such a candidate. For this study, we carried out LC-MS analysis of E. goetzei Henn aqueous extract (EgH-AE); then used the Caco-2 cell line for the model cells and treated the cells with t-BHP to form an oxidative stress system. An MTT assay was used for testing the biocompatibility and cytoprotective effects; reactive oxygen species and malondialdehyde determination was used for evaluating the antioxidative stress effect; TNF-α and IL-1ß were used for observing the anti-inflammatory effect, and 8-OHdG for monitoring anticancer activity. The results of this study demonstrate that the EgH-AE has very good biocompatibility with the Caco-2 cell line and has good cytoprotective, antioxidant, anti-inflammatory, and anticancer properties. It is clear that EgH-AE, a kind of ancient herbal tea, may be used to develop a functional beverage that can be given to people with a high BMI to protect against obesity-induced diseases.

Effects of different gastrointestinal reconstruction techniques on nutrition, anemia, and quality of life in laparoscopic distal gastrectomy for gastric cancer.

PURPOSE: To explore the effect of different gastrointestinal reconstruction techniques on laparoscopic distal gastrectomy of gastric cancer on the nutritional and anemia status, and quality of life (QoL) of patients. METHODS: Eligible patients were randomly divided into three groups (n=36/group): Billroth I anastomosis group, Billroth II combined with Braun anastomosis group, and Roux-en-Y anastomosis group. Related indicators were compared and analyzed. RESULTS: The general data were comparable among the three groups (all P>0.05). Among the surgical-related indicators and postoperative recovery indicators, only the comparison of the operation time was statistically significant (P=0.004). The follow-up time was 5~36 months (average 27.9 months). In terms of nutritional and anemia indicators, only the differences in the levels of prealbumin, hemoglobin and serum ferritin in 24 months after operation showed significant differences (P=0.015, P=0.003, P=0.005, respectively). There were no significant differences in hospital readmission rate, overall survival, and QoL among the three groups (all P>0.05). CONCLUSIONS: In laparoscopic gastrectomy for stage II~III distal gastric cancer, Billroth I anastomosis has shorter operation time than Billroth II combined with Braun anastomosis and Roux-en-Y anastomosis and advantages in the improvement of nutritional status and anemia recovery.
