Efficacy and Safety of AbobotulinumtoxinA for Treatment of Moderate-to-Severe Glabellar Lines: A Meta-Analysis.

PURPOSE: This meta-analysis aimed to evaluate the safety and efficacy of abobotulinumtoxinA (ABO) and ABO solution for injection (ASI) for treating moderate-to-severe glabellar lines. METHODS: The EMBASE, PubMed, and web of science databases were systematically searched. Methodological quality was checked using the Cochrane Risk of Bias tool. We also performed statistical analyses using Stata software to examine the efficacy and safety of ABO. RESULTS: Nine randomized controlled trials were included in the meta-analysis. The results showed that at maximum frown, the proportion of responders as measured by the investigator's live assessment and subject's self-assessment of moderate-to-severe glabellar lines were significantly higher in the ABO and ASI treatment groups than in the placebo group. In addition, from baseline to maximum frown, the ≥1-grade improvement rate in moderate-to-severe glabellar lines severity was also significantly higher in the ABO and ASI treatment groups than in the placebo group. No significant differences in adverse events were found between ABO, ASI and placebo groups, indicating that ABO and ASI have good safety. CONCLUSIONS: ABO and ASI are effective and safe options for the treatment of moderate-to-severe glabellar lines. More high-quality studies are needed to verify these conclusions.

Ononin Shows Anticancer Activity Against Laryngeal Cancer via the Inhibition of ERK/JNK/p38 Signaling Pathway.

Background: Laryngeal cancer is a type of head and neck tumor with a poor prognosis and survival rate. The new cases of laryngeal cancer increased rapidly with a higher mortality rate around the world. Objective: The current research work was focused to unveil the in vitro antitumor effects of ononin against the laryngeal cancer Hep-2 cells. Methodology: The cytotoxic effects of ononin against the laryngeal cancer Hep-2 cells and normal HuLa-PC laryngeal cells were studied using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. The intracellular Reactive Oxygen Species (ROS) generation, apoptotic cell death, Mitochondrial Membrane Potential (MMP), and cell adhesion on the 25 and 50 µM ononin-treated Hep-2 cells were detected using respective staining assays. The levels of TBARS and antioxidants were assayed using specific kits. The expressions of c-Jun N-terminal kinase 1/2 (JNK1/2), Extracellular Signal-regulated Kinase 1/2 (ERK1/2), p38, Phosphatidylinositol-3 Kinase 1/2 (PI3K1/2), and protein kinase-B (Akt) in the ononin-treated Hep-2 cells were investigated using Reverse Transcription-Polymerase Chain Reaction (RT-PCR) assay. Results: The ononin treatment effectively inhibited the Hep-2 cell viability but did not affect the viability of HuLa-PC cells. Furthermore, the ononin treatment effectively improved the intracellular ROS accumulation, depleted the MMP, and triggered apoptosis in Hep-2 cells. The Thiobarbituric acid reactive substances (TBARS) were improved, and Glutathione (GSH) levels and Superoxide dismutase (SOD) were depleted in the ononin-administered Hep-2 cells. The ononin treatment substantially inhibited the JNK/ERK/p38 axis in the Hep-2 cells. Conclusion: Together, the outcomes of this exploration proved that the ononin has remarkable antitumor activity against laryngeal cancer Hep-2 cells.
