Struggles in An Ancient City is a modern national opera of counter-Japanese war adapted from the novel of the same name written by Li Yingru. It is one of the most influential operas in the original opera of China in recent years. To commemorate the 60th anniversary of victory of Chinese counter-Japanese war and the world’s anti-fascist war in 2005, general administration opera creates and rehearse the opera. It is adapted from the main plot of the novel to show a story of struggle of our Party in the counter-Japanese war in an ancient city in the north. The paper is based on the VCD version of Struggle in An Ancient City. Through the reference study, analysis and conclusion, the female character in the opera, Jin Huan, is starting point to have a study with the samples of important singing part of Jin Huan, from the creation background to the music features of singing (including analysis of language, phonetics and singing). As to conclusion, there is a brief carding of the thread of the article to explain that factors such as emotion, mood, language are combined with female character’s performance of phonetic form in the Struggle in An Ancient City. Hope that the paper could make vocal enthusiasts to have a more comprehensive knowledge to Jin Huan in the opera. At the same time, the paper will carefully describe the singing analysis and singing processing of the analysis of song, so it may be reference for the vocal learning enthusiasts.

The ruminant digestive system harbors a complex gut microbiome, which is poorly understood in the case of the four stomach compartments of yak. High-throughput sequencing and quantitative PCR were used to analyse microbial communities in the rumen, reticulum, omasum, and abomasum of six domesticated yak. The diversity of prokaryotes was higher in reticulum and omasum than in rumen and abomasum. Bacteroidetes predominated in the four stomach compartments, with abundance gradually decreasing in the trend rumen > reticulum > omasum > abomasum. Microorganism composition was different among the four compartments, all of which contained high levels of bacteria, methanogens, protozoa and anaerobic fungi. Some prokaryotic genera were associated with volatile fatty acids and pH. This study provides the first insights into the microorganism composition of four stomach compartments in yak, and may provide a foundation for future studies in this area.

Purpose The purpose of this study was to identify novel plasma biomarkers for distinguishing nasopharyngeal carcinoma (NPC) patients from healthy individuals who have positive Epstein-Barr virus (EBV) viral capsid antigen (VCA-IgA). Materials and Methods One hundred seventy-four plasma cytokines were analyzed by a Cytokine Array in eight healthy individuals with positive EBV VCA-IgA and eight patients with NPC. Real-time polymerase chain reaction, Western blotting, enzyme-linked immunosorbent assay (ELISA), and immunohistochemistry were employed to detect the expression levels of macrophage migration inhibitory factor (MIF) and CC chemokine ligand 3 (CCL3) in NPC cell lines and tumor tissues. Plasma MIF and CCL3 were measured by ELISA in 138 NPC patients, 127 EBV VCA-IgA negative (VN) and 100 EBV VCA-IgA positive healthy donors (VP). Plasma EBV VCA-IgA was determined by immunoenzymatic techniques. Results Thirty-four of the 174 cytokines varied significantly between the VP and NPC group. Plasma MIF and CCL3 were significantly elevated in NPC patients compared with VN and VP. Combination of MIF and CCL3 could be used for the differential diagnosis of NPC from VN cohort (area under the curve [AUC], 0.913; sensitivity, 90.00%; specificity, 80.30%), and combination of MIF, CCL3, and VCA-IgA could be used for the differential diagnosis of NPC from VP cohort (AUC, 0.920; sensitivity, 90.00%; specificity, 84.00%), from (VN+VP) cohort (AUC, 0.961; sensitivity, 90.00%; specificity, 92.00%). Overexpressions of MIF and CCL3 were observed in NPC plasma, NPC cell lines and NPC tissues. Conclusion Plasma MIF, CCL3, and VCA-IgA combination significantly improves the diagnostic specificity of NPC in high-risk individuals.

A New Unsymmetrical Zinc Phthalocyanine as Photosensitizers for Dye-sensitized Solar Cells
Dan Zhang,Xue-Jun Zhang,Lei Zhang,Li-Jun Mao 대한화학회 2012 Bulletin of the Korean Chemical Society Vol.33 No.4
A new unsymmetrical zinc phthalocyanine has been designed and synthesized based on the ‘push-pull’ and extended π-conjugation concept for the dye-sensitized solar cells. Three tert-butoxy groups, which act as electron releasing (‘push’), enhance the solubility of phthalocyanine in common organic solvents and reduce the aggregation. Hydroxy substituted 9,10-anthraquinones act as electron acceptors (‘pull’) for the study of photoinduced electron transfer processes as well as grafting onto nanocrystalline TiO2. The new unsymmetrical zinc phthalocyanine was fully characterized by FTIR, UV-vis, 1H NMR, cyclic voltammetry and differential pulse voltammetry. The new sensitizer was tested in dye-sensitized solar cells, and gave a better performance.

Background/Aims: Older adults are vulnerable to central obesity, while the association of changes in central fatness with risk of diabetes and metabolic control has not been investigated among this particular population. This study was aimed to address these issues. Methods: A total of 1,815 adults aged ≥ 60 years without diabetes at baseline were followed for 4 years. Incident diabetes was ascertained based on plasma glucose, hemoglobin A1c, medical history, and/or the use of anti-diabetic drugs. Central fatness was assessed by waist circumference (WC), waist-height ratio (WHtR), and body roundness index (BRI). Logistic re gression analyses were used to assess the association of changes in central fatness with risk of diabetes, along with dose-re sponse and mediation analyses. Results: During the 4-year follow-up, 177 participants developed diabetes. The risk of diabetes was increased by 42%, 41%, and 40% per 1 standard deviation increases in WC, WHtR, and BRI, respectively, in multivariable-adjusted models (all p < 0.01). Moreover, these relationships were all linearly-shaped (all p<sub>nonlinearity</sub> ≥ 0.11). Increases in WC, WHtR, and BRI correlat ed with increases in hemoglobin A1c, triglycerides-and-glucose index, triglycerides, white blood cell, and C-reactive protein (all p ≤ 0.04). Yet only changes in hemoglobin A1c and triglycerides-and-glucose index were identified as the possible mediators for risk of diabetes, with their mediating effect being about 35% and 21%, respectively. Conclusions: Increases in central fatness were related to elevated risk of diabetes, and this association might be partly ex plained by the worsening of glycemic control and insulin resistance in older adults.

Ulcerative colitis (UC) is characterized by a low redox potential in the colon. Targeting redox-responsivestrategies are highly desirable due to the capacity of improving the treatment efficiency of drugs againstUC. Resveratrol (Res), a natural ingredient, possesses prominent anti-inflammatory activity. However, thelimited bioavailability and poor water-solubility severely hinder its clinical translation. Herein, we fabricatean oral delivery carrier of Res-encapsulated tetrasulfide-containing organosilica nanoparticles(DSMSNs), functionalized by targeting component chondroitin sulfate (CS). Benefiting from smart‘‘switch” and targeted ‘‘guider”, CS shell enables high internalization and promotes selective accumulationin colon epithelial cells and macrophages through CD44-mediated pathway; meanwhile, glutathione(GSH) response-mediated rapid disassembly exhibits targeted Res release and efficient biodegradation,consequently achieving enhanced intracellular delivery of Res, improved Res-enabled treatment andrecovered gut microbial diversity in the colitis model to mitigate colonic inflammation. These findingsthus bring fresh insights into the potential of MONs in UC treatment as an oral delivery platform.

Experimental and numerical studies on mechanical behavior of buried pipelines crossing faults
Dan F. Zhang,Xue M. Bie,Xi. Zeng,Zhen. Lei,Guo F. Du 국제구조공학회 2020 Structural Engineering and Mechanics, An Int'l Jou Vol.75 No.1
This paper presents a study on the mechanical behavior of buried pipelines crossing faults using experimental and numerical methods. A self-made soil-box was used to simulate normal fault, strike-slip fault and oblique slip fault. The effects of some important parameters, including the displacement and type of fault, the buried depth and the diameter of pipe, on the deformation modes and axial strain distribution of the buried pipelines crossing faults was studied in the experiment. Furthermore, a finite element analysis (FEA) model of spring boundary was developed to investigate the performance of the buried pipelines crossing faults, and FEA results were compared with experimental results. It is found that the axial strain distribution of those buried pipelines crossing the normal fault and the oblique fault is asymmetrical along the fault plane and that of buried pipelines crossing the strike-slip fault is approximately symmetrical. Additionally, the axial peak strain appears near both sides of the fault and increases with increasing fault displacement. Moreover, the axial strain of the pipeline decreases with decreasing buried depth or increasing ratios of pipe diameter to pipe wall thickness. Compared with the normal fault and the strike-slip fault, the oblique fault is the most harmful to pipelines. Based on the accuracy of the model, the regression equations of the axial distance from the peak axial strain position of the pipeline to the fault under the effects of buried depth, pipe diameter, wall thickness and fault displacement were given.

<P>A magnetorheological (MR) fluid, composed of soft magnetic carbonyl iron (CI) particles dispersed in a nonmagnetic carrier fluid, was prepared with an additive of nanoporous Fe-MCM-22 particles. Fe-MCM-22 was synthesized by a hydrothermal method and was used to prevent fast settling of the CI particles in the MR fluid system. Two MR fluids comprised of the same CI particles in 25% volume fraction were prepared, but one having additional 5 wt% Fe-MCM-22 according to the carrier fluid weight. Performance of these MR fluids, including shear stress, shear viscosity and yield stress, were measured using a rotational parallel disk rheometer in a steady flow. Suspension stability and magnetic properties were also examined by a Turbiscan apparatus and a vibrating sample magnetometer, respectively. The addition of Fe-MCM-22 into the CI suspension was found to improve not only MR properties including field dependent yield stress, but also dispersion stability of the suspension.</P>
