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.

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.

Objective To study the effect of family intervention on treatment compliance and social function for patients with schizophrenia.Methods 76 patients with schizophrenia were randomly divided into the intervention group and the control group with 38 cases in each group.The patients in both groups were treated with antipsychotics,the control group was only given general hygiene education,while the intervention group was given targeted systematic family intervention for 1 year.The Nurse-Brief Psychiatric Rating Scale (N-BPRS),Social Disability Screening scale (SDSS),Insight and Treatment Attitudes Questionnaire (ITAQ),medication adherence questionnaire were used before and after the intervention and then the recurrence rate within 1 year was calculated.Results At the end of 1 year the total scores of NBPRS,SDSS,medication adherence questionnaire significantly decreased in the intervention group and were signif-icantly lower than those of the control group at the same period,while the total score of ITAQ significantly increased in the intervention group and was significantly higher than those of the control group at the same period.The recurrence rate of the intervention group was significantly lower than the control group.Conclusions The family interventions contribute to promote insight recovery of the patients with schizophrenia ef-fectively and improve their treatment compliance,reduce recurrence and to promote the recovery of its so-cial function.

Objective To evaluate the changes of the upper airway of the patients with obstructive sleep apnea syndrome (OSAS) before and after operations and to know the effects of operations by MSCT. Methods The upper airway dimensions of 26 patients with OSAS were measured on multiplanar reformatted (MPR), curved-planar reformatted (CPR), volume rendering(VR) images of 16-slice spiral CT. The measurements include the anteroposterior calibres and the areas on the reformatted axial images on the pharyngeal cavity levels, the calibres and the minimum areas in retropalatal and retroglossal regions, the areas of the soft palate and uvula on the reformatted sagittal view with maximum thickness, the maximum wall thickness of the right and left the upper airway on the coronary images, the volume of the upper airway before and after the operations. The measurements were correlated with the polysomnography (PSG) records. The data were analyzed paired-samples t-test and Pearson correlations. Results By comparison, the anteroposterior calibres and the cross-sectional areas on the reformatted axial view of the lower retropalatal region (slice 4) of the upper airway increased significantly after operations. The anteroposterior diameter increased from 5. 9 mm before operations to 12.8 mm after operations, where t = - 5.506, P < 0.05. The areas increased from 51.0 mm~2 before operations to 275.0 mm~2 after operations, where t = -5.011, P <0.05. In the higher retropalatal region (shce 2) of the upper airway, the anteroposterior diameter decresased from 14.8 mm before operations to 9.2 mm after operations, where t = 2.867, P < 0.05. The areas decreased from 241.0 mm~2 before operations to 128.0 mm~2 after operations, where t = 3.087, P < 0.05. The anteroposterior calibres of retroglossal region (slice 7) decreased from 12.7 mm before operations to 10.3 mm after operations,where t = 3.718, P <0.05. The L-R calibres and the minimum areas of of retropalatal increased significantly from 6.4 mm, 33.0 mm~2 before operation to 10.9 mm, 76. 0 mm~2 after operation, where t = -3.413, -2. 216, respectively and P < 0.05. Of the 9 cases whose apnea and hypopnea index (AHI) ≤5 events/hour after operations, the minimum areas of retropalatal region, the anterio-posterior diameter, L-R calibres increased significantly. The areas increased from 41.0 mm2 before operations to 76.0 mm~2 after operations, were t = -4. 932, P <0.05. The anteroposterior calibres increased from 4.6 mm before operations to 6.6 mm after operations, where t = - 7. 308, P < 0.05. The L-R calibres increased from 8.3 mm before operations to 13.6 mm after operations, where t = - 4.320, P < 0.05. Conclusions MPR、CPR、VR of MSCT can evaluate the not only the morphology but the function changes of the upper airways on the OSAS patients. The increasing of the minimum cross-sectional area may be one of the important indications for evaluating operations. The narrowing of the higher retropalatal region of the upper airway after operations should be an alert to the clinicians.

Objective To analyze the risk factors that affect severe infection following flexible ureteroscope Holmium laser lithotripsy for upper urinary tract calculus,and to construct the regression model and nomogram for predicting the probability of postoperative SIRS.Methods We retrospectively analyzed the clinical data from 457 cases (male 302 and female 155) of upper urinary calculi treated by flexible ureteroscopy from January 2014 to May 2016,with mean age of 49.9 (ranged 20-76) years.The mean maximum size of stones was (16.5 ± 3.0) mm (ranged 12-22rmm).There were 51 cases (11.2％) with a recent infectious febrile history related to stones.The patients were divided into two groups as patients developing SIRS or not.Univariate and multivariate statistical analyses were performed to determine factors affecting the development of postoperative SIRS,and then a nomogram was built based on regression coefficients.Results The incidence of SIRS after flexible ureteroscopic lithtripsy was 5.9％ (27/457).Multivariable logistic regression analysis identified febrile history related to urinary stones (OR =1.5569,P =0.009),without preoperative placement of ureteral stent (OR =1.4004,P =0.004),small-caliber (F 13-14) ureteral access sheath (OR =1.1120,P =0.016),endoscopic signs of infection (OR =2.0176,P =0.000) and infectious stones (OR =1.0981,P =0.013) as independent risk factors for postoperative SIRS.The concordance index was 0.845 in the nomogram model sample and 0.79 in the validation sample.Conclusions Febrile history related to urinary stones,without preoperative placement of ureteral stent,small-caliber ureteral access sheath,endoscopic signs of infection and infectious stones would be independent risk factors to predict SIRS after flexible ureteroscope holmium laser lithtripsy.A nomogram based on perioperative clinical factors could be used to predict the risk of SIRS.

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.
