Objective To optimize the extraction technology of perilla seeds oil from the oil cake of perilla seeds (OCPS) by using the contents of active fatty acids as evaluation standard. Methods The fatty acids were extracted from OCPS,the residue of perilla seeds after cold-press, by smashing tissue extraction (STE), the new technology selected through comparing with classical leaching extraction (LE), Soxhlet extraction (SE), ultrasonic extraction (UE), and supercritical-CO2 fluid extraction (SFE). For optimized condition of STE, orthogonal test was designed and completed. The contents of five fatty acids in extracted oil and OCPS were determined by GC. Results The optimized extraction parameters were smashing for 1.5 min under extraction power of 150 W and 1:6 of the material/solvent ratio. The contents of five fatty acids in the oils extracted by five techniques from OCPS and determined by GC were as follows:a-linolenic acid (41.12%-51.81%), linoleic acid (15.38%-16.43%), oleic acid (18.93%-27.28010), stearic acid (2.56%-4.01%), and palmitic acid (7.38%-10.77%). Conclusion The results show that STE is the most efficient technology with the highest yield (LE:0.57%; SE:1.03%; UE:0.61%; SFE:0.8(r; STE:1.17%) and shortest time (LE:720 min; SE:360 min; UE:30 min; SFE:120 min; STE:1.5 min) among five tested extraction technologies. It is fast reported using STE to extract herbal oil enriched with active fatty acids.

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.

Background and purpose:More and more evidence has showed that Grb2 binding protein-2 (Gab2) is associated with tumor invasion and metastasis. However, the relationship between Gab2 and epithelial-mesenchymal transition (EMT) in breast cancer is not clear. The aim of this study is to investigate the effect of Gab2 on EMT markers and the mechanism of Gab2 on breast cancer invasion and metastasis.Methods:Immunohistochemical methods were used to detect the expressions of Gab2, E-cadherin and vimentin in 80 cases of breast cancer tissues, and the correlations between them were analyzed. Western blot was used to detect the expression of Gab2 in breast tissues. After MDA-MB-231 cells were transfected with siRNA plasmid, wound healing assay was used to detect the invasive ability of transfected cells induced by epithelial growth factor (EGF) in vitro. Then Western blot was used to analyze the protein expressions of E-cadherin, vimentin, phosphorylated GSK-3β (p-GSK-3β) and nuclear Snail.Results:Gab2 was negatively correlated with the expression of E-cadherin and positively correlated with the expression of vimentin in breast cancer tissues (P<0.05). The expression of Gab2 in breast cancer tissues was higher than that in normal breast tissues adjacent to breast cancer. In vitro, Gab2 expression was significantly knocked down in MDA-MB-231 cells transfected with Gab2 siRNA plasmid (SiGab2/MDA-MB-231cells). Meanwhile, the invasive ability of SiGab2/MDA-MB-231cells was decreased with EGF stimulation. The expression of E-cadherin was increased in SiGab2/MDA-MB-231cells. However, the expressions of vimentin, p-GSK-3β and nuclear Snail were decreased in SiGab2/MDA-MB-231cells.Conclusion:Gab2 can promote the invasion and metastasis of breast cancer by EMT through GSK-3β/Snail signaling pathway.

Objective To assess the efficacy and safety of flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy in the treatment of upper urinary tract calculi.Methods The flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy was performed on 26 patients from Jul 2005 to Jan 2007. Among these patients, 8 had bilateral renal calculi and ureteral calculi, 5 had multiple renal calculi, 4 had renal calyx calculi and 9 had ureteral calculi. The average diameter of the calculus was 2.2 cm (range from 1.0-3.2 cm). Four patients had mild hydronephrosis, others had moderate or severe hydronephrosis. Insufficient renal function was noted in 13 cases. The procedure was performed via a single tract through the middle calyx under the ultrasonic guidance in all cases.Results Twenty-two cases achieved stone free at primary procedure, secondary procedure was needed in 4 cases. A 18 F tract was used in 18 cases and 24 F tract was used in the left 8 cases. The average operation time was 72 min, stone-free rate was 96.2%(25/26),and there was no blood transfusion. One patient had fever after the procedure and recovered 2 days after the administration of antibiotics. No other complication was recorded. In an average 11 month follow-up in 22 patients, hydronephrosis reduction was significant observed by ultrasound scan. No calculus relapse was found.Conclusions Flexible cystoscope conducted holmium laser lithotripsy via percutaneous nephrostomy is an effective and minimally invasive technique for the treatment of upper urinary tract calculus. It has the advantages in dealing with the calyx and ureteral calculus located in the proximal or middle segment as well.
