BACKGROUND: Nuclear factor kappa B (NF-κB) is possibly related to regulation of various cell signals that are derived from aqueous uveoscleral outflow pathway.OBJECTIVE: To explore effect of travoprost on the expression of NF-κB and inhibitor-κB (I-κB) in human ciliary muscle cells cultured in vitro. DESIGN, TIME AND SETTING: A contrast study, which was performed in the Laboratory of Zhongshan Ophthalmology Center from March 2005 to November 2006.MATERIALS: Eyeballs were obtained from the youth who died due to other diseases except eye disease no more than one hour. The relatives voluntarily provided the informed consent.METHODS: Travoprost (1 μmol/L) was added in human ciliary muscle cell culture medium, and then the samples were divided into four groups according to culture time, including 0-hour (control group), 6-hour, 12-hour, and 24-hour experimental groups. MAIN OUTCOME MEASURES: Expression of mRNA and protein of NF-κB p65 and I-κBα in the four groups by using real-time RT-PCR, immunofluorescence relative quantitative analysis and enzyme linked immunosorbent assay (ELISA) techniques. RESULTS: As compared to control group, mRNA expression of NF-κB p65 in the 6-hour, 12-hour, and 24-hour experimental groups was decreased (F=17.068, P=0.001); while mRNA expression of I-κBα was not changed remarkably in the 6-hour and 12-hour experimental groups (P > 0.05), but the expression was significantly higher than that in the 24-hour experimental group (F=32.742, P=0.000). Immunofluorescence relative quantitative analysis showed that the fluorescence intensity of NF-κB p65 in the 6-hour, 12-hour, and 24-hour experimental groups were weaker than that in the 0-hour control group (F=17.216, P=0.000); additionally, as compared to 0-hour control group, fluorescence intensity of I-κBα in the 6-hour experimental group was not changed remarkably (P=0.134), that in the 12-hour experimental group was weakened (P=0.032), and that in the 24-hour experimental group was strengthened (F=17.346, P=0.001). ELISA revealed that expression of phosphorylated NF-κB p65 was decreased gradually by the time of being induced by travoprost (F=15.4, P=0.001). CONCLUSION: Travoprost can down-regulate mRNA expression of NF-κB p65, inhibit nuclear translocation, and up-regulate mRNA expression of I-κBα in human ciliary muscle cells.

A rapid method was developed for the determination of 5 common fatty acids, palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid in industrial oleic acid based on ultra_performance convergence chromatography_mass spectrometry ( UPC_MS) . The sample was dissolved by n_hexane, followed by clean_up of extract using 0. 22 μm organic phase filter. The fatty acids were separated in 3 min on the column of Acquity UPC2 BEH 2_EP by gradient elution with carbon dioxide and methanol/acetonitrile (1∶1, V/V) system, and finally detected by MS detector in ESI- mode. Through the optimization of UPC2_MS condition, the reasonable linearity was achieved for all the analytes over the range of 0. 5-100 mg/L with the correlation coefficients ( R2 ) greater than 0. 9985. The recoveries for five fatty acids at three spiked levels were in the range from 89 . 3% to 106 . 67% with relative standard deviations of 0 . 8%-3 . 0%. The limits of detection for target compounds in the method ranged from 0. 07 mg/L to 0. 26 mg/L. The real sample analysis showed that this method was simple,fast and had a good separation effect. There was no need of derivatization for fatty acid samples. This work would provide a fast and effective detection method for UPC2 technology in oil related research field.
