Objective:To establish a headspace capillary GC method for the determination of residual solvents in bromfenac sodi-um. Methods:A headspace GC was used to separate the residual solvents on an HP-5 capillary column with an FID detector. The car-rier gas was nitrogen at the flow rate of 0. 8 ml·min-1 . The temperature of the injector was 200 ℃ and that of the FID was 250 ℃. The programmed column temperature was set as follows:maintained at 40℃ for 10 min, and then raised to 150℃ at the rate of 30℃·min-1 and maintained for 5 min. The containers of headspace injector were in equilibrium at 100 ℃ for 20 min. Dimethyl sulfoxide was used as the solvent. The amount of the residual solvents, such as methylbenzene, isopropanol, dichloromethane, methanol and iso-propyl ether was calculated by an external standard method. Results:All the solvents could be completely separated with good linear relationship. The average recovery of the five solvents was 98. 9%( RSD =2. 01%),99. 2% ( RSD =1. 95%),99. 6% ( RSD =1. 65%),100. 5%(RSD=1. 38%)and 100. 8%(RSD=1. 36%)(n=9),respectively. Conclusion:The method is simple and accu-rate in the determination of the five residual solvents in bromfenac sodium.

Background and purpose: Bladder cancer is the most common urological malignancy in our country which seriously threatens human health, and its incidence increased year by year. This study aimed to investigate the effects of hinokitiol on the proliferation, apoptosis and autophagy in human bladder cancer cell lines. Methods:CCK-8 assays were performed to analyze the effects of hinokitiol on the proliferation of J82 cells. Apoptosis rate was determined by lfow cytometry. Cleaved caspase 3, LC3 and P62 protein expression was determined using Western blot. EGFP-LC3 microscopy assay was performed to assess autophagy. Results: Hinokitiol significantly inhibited the proliferation of J82 cells and induced cell apoptosis via caspase pathway. The apoptosis effect of hinokitiol could be partially antagonized by Z-VAD-FMK. Hinokitiol induced autophagy of J82 cells, increased LC3 expression and down-regulated P62 expression. 3-MA is able to rescue Tet-induced cell death. Conclusion:Hinokitiol can inhibit the proliferation of J82 cells and induce cell apoptosis via autophagy activation.
