Quercetin Inhibits the Migration and Invasion of HCCLM3 Cells by Suppressing the Expression of p-Akt1, Matrix Metalloproteinase (MMP) MMP-2, and MMP-9.

BACKGROUND Quercetin is a natural bioactive flavonoid that is present in a wide variety of vegetables and fruits and exhibits a promising anti-metastasis property in various human cancer cells. However, the effect of quercetin on human HCCLM3 cells is unclear. MATERIAL AND METHODS In the current study, a wound-healing assay was performed using quercetin-treated HCCLM3 cells to further explore whether quercetin affects the motility of human HCCLM3 cells.

[Effect of Echinococcus multilocularis Infection on the Activities of Drug-metabolizing Enzymes in Gerbil Liver].

Objective: To study the effect of Echinococcus multilocularis infection on the activities of drug-metabolizing enzymes in gerbil liver.

Methods: Ten gerbils （Meriones unguiculatus） were randomly divided into 2 groups, the experimental group in which each animal was intraperitoneally injected with 300 μl E. multilocularis cyst homogenates （containing about 600 protoscoleces）, and the control group in which each animal received 300 μl saline（i.

Immune cell inflammatory cytokine responses differ between central and systemic compartments in response to acute exercise in mice.

Background: Exhaustive exercise induces apoptosis and oxidative stress in systemic organs and tissues and is associated with increased levels of pro-inflammatory cytokines. The effects of acute exercise on cytokine expression and apoptosis of immune cells in the central nervous system (CNS) have not been well characterized.

Purpose: We investigated the effects of a single bout of strenuous exercise on the expression of TNF-alpha, IL-6, and IL-beta, as well as the apoptotic status of cells in the hippocampus of healthy mice.

A systematic meta-analysis of randomized controlled trials of adjuvant chemotherapy for localized resectable soft-tissue sarcoma.

Background: The use of adjuvant chemotherapy to treat adults with localized resectable soft-tissue sarcoma remains controversial. The objective of this systematic review was to update the 1997 meta-analysis of randomized controlled trials (RCTs) to reassess the efficacy of doxorubicin-based chemotherapy with respect to recurrence and survival.

Methods: A comprehensive literature search was performed to identify RCTs of adjuvant chemotherapy for adult patients diagnosed with localized resectable soft-tissue sarcoma.
