Abstract
BACKGROUND To compare the efficiency and safety of uterine artery embolization (UAE) combined with local infusion of methotrexate (MTX) or MTX and 5-fluorouracil (5-FU) in the treatment of ectopic pregnancy (EP). METHODS One hundred women with EP were prospectively enrolled from December 2012 to February 2015 and randomly allocated into 2 groups. One group was treated with UAE combined MTX, and the other with UAE combined with MTX and 5-FU. Local MTX was administrated at a dose of 80 to 120 mg, based on the initial β-human chorionic gonadotropin (β-HCG) levels, and 5-FU was given intra-arterially at a uniform dose of 0.5 g. RESULTS Bilateral UAE was successfully performed in all 100 patients, 88 of whom were clinically successfully treated, 45 (91.8%) in the MTX group, and 43 (87.8%) in the MTX + 5-FU group; 89% of the patients achieved normalization of β-HCG below 70,000 mIU/mL within 14 to 21 days postoperatively. The time to successful β-HCG resolution was 26.74 ± 5.57 days for patients receiving MTX + UAE treatment, and 27.57 ± 5.08 days for those treated with additional 5-FU. Six patients had subsequent intramuscular injections of MTX and 6 had a unilateral salpingectomy after the treatment failure. Mild immediate side effects accounted for 24.5% in the sole MTX and 58.3% in MTX + 5-FU group. CONCLUSION A combination of UAE and intrauterine infusion of MTX showed comparable efficiency to UAE combined with a local infusion of MTX and 5-FU in treating EP patients with the intention to preserve fertility.

Abstract
OBJECTIVE To investigate the impact of all-trans retinoic acid (ATRA) on chemosensitivity to esophageal squamous cell carcinoma EC9706 cells in vitro and its mechanism. METHODS EC9706 cells were routinely cultured as the control group. The experimental group was divided into three groups. The ATRA group with ATRA in final concentration of 1 µmol/L; the 5-Fu group with 5-Fu in final concentration of 50 mg/L; the combined treatment group with ATRA in final concentration of 1 µmol/L and 5-Fu 50 mg/L. The cell apoptosis was detected by terminal deoxynucleotidy transferase mediated dUTP nick end labelling (TUNEL). The cell cycle and apoptosis were detected by flow cytometry. RESULTS The results of TUNEL showed that in the combined treatment group appeared a large number of apoptotic cells, and their nuclei were stained brown, with a positive rate of 89.7%. There was a significant difference in the comparison with the ATRA group (38.3%) and 5-Fu group (40.3%) (P < 0.05). The flow cytometry showed that the ATRA + 5-Fu group had a significantly higher apoptosis rate (76.9% ± 2.7%) than that in the ATRA group (38.2% ± 2.6%) and 5-Fu group (45.2% ± 2.3%) (P < 0.05). The ratio of cells in G(1) phase increased in the ATRA + 5-Fu group (83.4% ± 3.0%), significantly higher than (48.2% ± 2.5%) in the ATRA group and (53.2% ± 2.6%) in the 5-Fu group (P < 0.05). The ratio of cells in S + G(2)/M phase was decreased in the ATRA + 5-Fu group, with a significant difference (P < 0.05) when compared with other groups. There was no significant difference between the ATRA group and 5-Fu group (P > 0.05) in the apoptosis rate and the proportion of cells at different phases. CONCLUSION ATRA can induce apoptosis of esophageal carcinoma EC9706 cells in vitro. The combination of ATRA and 5-Fu may enhance the chemotherapeutic efficacy.
