2012年计算机应用与系统建模国际会议

作者： Zhuo Li wang Ting HaoJian Zhong wang shuling Department of Fundametal Course Xu Zhou Air Force College

We demonstrate 3R-regeneration method based on XPM in PCF. The most important part of this system is a MZI Optical Switch which have one high-Nonlinear PCF arm. By adjusting the length of the PCF, we can make the centre of the optical pulse obtain a phase shift about π, this optical pulse transmitted through the PCF interfere with the optical pulse transmitted through the other arm, the degraded data signal get regeneration . The experiment is simulated with Optisystem.

Journal of Nanjing Medical University 2006年第6期20卷 355-359页

作者： Gang Yang Chao Chang YuQing wang Yibo Feng shuling Rong Department of Cardiology Union hospital Tong ji Medical College of Huazhong University of Science and Technology Wuhan 430022 China

Objective： To investigate the inhibitory effect of caffeic acid phenethyl ester（CAPE） on the proliferation of vascular smooth muscle cells （VSMC） activated by lipopolysaccharide （LPS） and to clarify its mechanism. Methods： VSMC activated by LPS （1 mg-L^-1） were treated with CAPE at different concentrations. The inhibitory effecfs of CAPE on the proliferation of VSMC were determined by methabenzthiazuron（MTT） colorimetry. The effects of CAPE on the expression of proliferating cell nuclear antigen （PCNA） and Survivin protein in VSMC were evaluated by immunocytochemistry staining technique （SABC method）. Cell cycle was analyzed by flow cytometry（FCM） with propidiumiodide （PI） labeling method. The relative expression level of Survivin mRNA was measured with real-time quantified RT-PCR technique. Results. CAPE exerted significant inhibitory effects on. proliferation of VSMC at concentrations ranging from 5 mg·L^-1 to 80 mg·L^-1, decreased the rate of cells positive for PCNA and Survivin protein and repressed the expressioh of Survivin mRNA in a dose- and time-dependent manner （P 〈 0.05）. FCM analysis displayed that CAPE up-regulated the ratio of G0/G1 stages and reduced the percentage of VSMC in S stage （P 〈 0.05）. Conclusion： CAPE can significantly inhibit the proliferation of VSMC activated by LPS in a dose- and time-dependent manner, which may be carded out through regulating cell cycle and repressing the expression of PCNA and Survivin.

目的探讨子宫颈高级别鳞状上皮内病变(HSIL)及子宫颈癌阴道镜检查漏诊的影响因素。方法回顾性分析2017年1月至2022年6月于山西医科大学第二医院行阴道镜检查并经组织病理诊断确诊为HSIL及子宫颈癌的957例患者的临床资料,采用logistic回归分析阴道镜检查漏诊HSIL及子宫颈癌的影响因素。结果单因素分析结果显示,HSIL及子宫颈癌阴道镜检查漏诊与是否绝经、有无同房出血、有无不规则出血、液基薄层细胞学(TCT)结果、子宫颈形态、醋酸白试验结果、碘试验结果、有无腺体白环、有无镶嵌、有无点状血管、转化区是否完全可见、转化区类型及病变是否累及腺体均有关(均P0.05)。多因素logistic回归分析结果显示,不规则出血(OR=4.279,95%CI 2.170~8.441,P<0.001)、TCT结果为非典型鳞状上皮细胞意义不明确(ASC-US)(OR=0.415,95%CI 0.226~0.761,P=0.004)、TCT结果为不典型鳞状上皮细胞不除外高级别鳞状上皮内病变(ASC-H)/HSIL(OR=0.389,95%CI 0.206~0.735,P=0.004)、醋酸白试验结果为厚醋酸白上皮(OR=0.015,95%CI 0.004~0.055,P<0.001)及点状血管(OR=0.327,95%CI 0.173~0.616,P=0.001)是HSIL及子宫颈癌阴道镜检查漏诊HSIL及子宫颈癌的独立影响因素。结论有不规则出血史是阴道镜检查漏诊子宫颈HSIL及子宫颈癌的危险因素,而TCT结果为ASC-US、ASC-H/HSIL及阴道镜下见厚醋酸白上皮、点状血管可降低漏诊发生风险。
