Anticancer Activity of Mukonal Against Human Laryngeal Cancer Cells Involves Apoptosis, Cell Cycle Arrest, and Inhibition of PI3K/AKT and MEK/ERK Signalling Pathways.

BACKGROUND Laryngeal cancer is one of the major malignancies of the neck and head and is responsible for considerable mortality across the globe. The treatments for laryngeal cancer mainly involve surgical interventions followed by chemotherapy. However, due to unsatisfactory results, constant relapses and the adverse effects associated with the currently used drugs, there is pressing need to develop effective drug options for treatment of laryngeal cancer. Therefore, this study was undertaken to investigate the anticancer effects of a plant-derived alkaloid, Mukonal, against human AMC-HN-8 laryngeal cancer cells. MATERIAL AND METHODS The WST-1 and clonogenic assays were employed to determine the cell viability. Apoptosis was detected by Hoechst and AO/EB staining. Cell migration and cell cycle analysis was performed by Transwell assay and flow cytometry, respectively. Protein expression was examined by Western blotting. RESULTS The results revealed that Mukonal reduced the viability of laryngeal cancer cells dose-dependently. The IC50 of Mukonal was found to be 10 µM. However, the effects of Mukonal on the normal HuLa-PC cells was found to be 140 µM. The decrease in the viability of the AMC-HN-8 laryngeal cancer cells was found to be due to the induction of apoptosis and G2/M cell cycle arrest. Mukonal also suppressed the cell migration and of the AMC-HN-8 laryngeal cancer cells. Mukonal could also inhibit the PI3K/AKT and MEK/ERK signalling pathways in a concentration-dependent manner. CONCLUSIONS Taken together, we conclude that Mukonal could prove a beneficial lead molecule for the treatment of laryngeal cancer.

The value of three-dimensional medical imaging guided ultrasound in the treatment of huge hepatic hemangioma / 中华医学超声杂志（电子版）

Objective To evaluate the clinical application value of three-dimensional medical image guided ultrasound in the chemotherapy of huge hepatic hemangioma.Methods Seventy-six cases were enrolled in a randomized control study.All cases were randomly divided into two groups (group A and group B).In group A,all cases underwent treatment based on the traditional two-dimensional medical images.Under the assistance of three-dimensional medical image information,preoperative treatment planning was performed in group B.After puncture treatment,therapeutic efficacy was evaluated by color ultrasound during follow-up.Results For treating huge hepatic hemangioma (tumor diameter ≥ 10.0 cm),the insertion number and pingyangmycin dosage in the group B were less than those in the group A [(6.2± 0.5)times vs (9.3±0.6) times,t=24.467,P=0.035;(99.2±8.0) mg vs (148.8±9.6) mg,t=34.613,P=0.029].The success rate of first treatment in the group B was higher than that in group A [73.6％(28/38) vs 100％(38/38),x2=131.91,P=0.032].Conclusion For huge hepatic hemangioma,the three-dimensional medical image information can be applied to reduce the insertion number and anesthetics dosage,improving the success rate of first treatment and therapeutic effect.
