This paper takes Wuxi Opera, a precious cultural treasure in Jiangsu province, China, for example. We will discuss the difficulties in spreading Wuxi Opera globally and learn the successful globalizing experience from other operas, such as Peking Opera, Kunqu Opera and Sichuan Opera. Considering the important status and rich resources of Peking Opera, we will analyze Peking Opera thoroughly and the most important aspects of Sichuan Opera and Kunqu Opera. By analyzing their translations and globalization process, we believe that Wuxi Opera should make efforts especially in four aspects to make progress in its globalizing campaign.展开更多

Methods A repeat HIV testing within 12 months was recorded if individuals had their first test with negative results, during 2013-2014 and retested within 12 months. An incident HIV diagnosis was recorded if individuals had their first test with negative results, during 2013-2015 and had a subsequent positive result at any point by the end of 2015. Data on HIV testing and diagnosis among individuals attending 32 VCT clinics from 2013 to 2015 and HIV diagnosis from other clinical services in Wuxi, China, were retrieved. A multivariate logistic regression model was used to analyze factors associated with repeat HIV testing. Cox regression was used to evaluate factors associated with incident HIV diagnosis. Results From 2013 to 2014, 11,504 individuals tested HIV negative at their first recorded test, with 655 （5.7%） retesting within 12 months. Higher repeat HIV testing within 12 months was associated with male gender [adjusted odds ratio （a OR） = 1.7, 95% confidence interval （CI）： 1.4-2.2], risk behaviors [commercial heterosexual behaviors （a OR = 1.4, CI： 1.1-1.6）, male-male sexual behaviors （a OR = 3.7, CI： 2.7-4.9）], injection drug use （a OR = 9.9, CI： 6.5-15.1）, and having taken HIV tests previously （a OR = 2.0, CI： 1.6-2.4）. From 2013 to 2015, 1,088 individuals tested negative on HIV test at their visit and at ≥ 2 subsequent tests; of them 30 had incident HIV diagnosis. The overall rate of incident HIV diagnosis among all VCT individuals was 1.6 （95% CI： 1.1-2.1） per 100 person-years. Incident HIV diagnosis was associated with male gender [adjusted hazard ratio （a HR） = 8.5, 95% CI： 1.9-38.1], attending hospital-based VCT clinics （a HR = 7.8, 95% CI： 1.1-58.3）, and male-male sexual behavior （a HR = 8.4, 95% CI： 1.5-46.7）. Individuals diagnosed at VCT clinics had higher CD4＋ T cell count compared with those diagnosed at other clinical services （median 407 vs. 326 copies/mm3, P = 0.003）. Conclusion VCT individuals in Wuxi, China, had a low repeat HIV testing rate and high HIV incidence. VCT-clinic-based interventions aimed at increasing repeat HIV testing are needed to detect more cases at an earlier stage, especially among individuals at high risk for HIV infection such as men who have sex with men.展开更多

Meanwhile, combined with mcteorological conditions and results of systemic inves-tigation, the study especially analyzed meteorological conditions, outbreak and prevalence regularity of TMV and control efficacy of chemical reagents against TMV. The results showed that climatic conditions were the main conditions affecting TMV. There were three occurrence peaks of TMV in 2011, as a result of meteorologi-cal conditions of the months from April to June. The peaks were concerned with a wide range of rainfall about half a month before, low temperature, high humidity and scant sunshine and temperature jump after rain. The results of control effects showed that the chemical reagents could obviously prevent TMV, but once tobacco plants were infected, spraying chemical reagents would not have effective control effect against TMV.展开更多
