Objective: To explore the effects of quercetin and quercetin in combination with cisplatin on adhesion, migration and invasion of HeLa cells.
Methods: Adhesion, migration and invasion of HeLa cells treated with quercetin and quercetin in combination with cisplatin were measured by adhesion assay, wound healing assay, and transwell chamber method respectively.
Results: The results showed that quercetin and quercetin in combination with cisplatin could inhibit adhesion, migration and invasion of HeLa cells. The adhesive ratio, migration rate and the invasiveness were negatively proportional to concentration of quercetin and quercetin in combination with cisplatin. With increasing concentration of quercetin from 20 to 80 micromol/L, the adhesive ratio decreased from (82.2 +/- 1.5)% to (48.4 +/- 1.1)%; the migration rate decreased from (7.26 +/- 0.20) microm/h to (3.78 +/- 0.64) microm/h; the invasiveness decreased from (124.3 +/- 1.5) piece to (90.7 +/- 2.1) piece (P < 0.05). In quercetin and quercetin in combination with 10 micromol/L cisplatin treatment group, with quercetin concentration increasing from 20 to 80 micromol/L, the adhesive ratio decreased from (42.6 +/- 1.2)% to (27.5 +/- 1.7)%, the migration rate decreased from (2.20 +/- 0.33) microm/h to (0.72 +/- 0.19) microm/h and the invasiveness decreased from (78.7 +/- 2.5) piece to (44.0 +/- 4.0) piece (P < 0.05). Compared with the quercetin groups, quercetin in combination with cisplatin groups had significantly higher inhibitory effects (P < 0.05).
Conclusions: Quercetin and quercetin in combination with cisplatin can inhibit adhesion and migration and invasion of HeLa cells. Quercetin can enhance the inhibitory effect of cisplatin on HeLa cell adhesion, migration and invasion.

Unlabelled: This study investigates the optimization of bioactive components in thermosonicated black carrot juice using response surface methodology (RSM) and gradient boosting (GB) modeling techniques. Thermosonication, a combination of ultrasound and heat, was applied to enhance the nutritional quality of black carrot juice, which is rich in anthocyanins, phenolic compounds, and antioxidants. The study examined the effects of temperature, processing time, and ultrasonic amplitude on total carotenoid content (TCC), total anthocyanin content (TAC), ferric reducing antioxidant power (FRAP), and total phenolic content.

Introduction: As a widely used Chinese herbal medicine, Mume Fructus pulp (MFP) has rich nutritional value and biological activity, but its quality control research is relatively scarce.
Objectives: The objective of the study was to evaluate the quality difference between MFPs from different origins and its adulterant apricot pulp (APP), and to identify potential quality markers.
Methods: The chemical compositions were identified by untargeted metabolomics analysis based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry combined with feature-based molecular networking.
