1研发投资决策下的现金股利分配:抑制还是迎合——兼论“半强制分红政策”的监管悖论显示文摘研发和股利分配同属于财务分配的范畴,二者存在现金流竞争。基于2007—2015年沪深A股上市公司数据的实证研究表明:研发投资对现金分红决策具有正向影响,现金流竞争强化了研发投资对现金分红的正向效应;证监会的“半强制分红政策”是导致上市公司“边研发、边分红”这一“研发一分红”关系悖论的原因,而“研发一分红”悖论会带来负面的财务效应;中国上市公司出现“研发一分红”关系悖论这一财务现象,说明证监会实施的“半强制分红政策”存在不足。杨宝 万伟 Daisy Chow 2018山西财经大学学报2018,40,3:18
2Aneuploidy of chromosome 8 in circulating tumor cells correlates with prognosis in patients with advanced gastric cancer显示文摘Objective: Previous work indicated that aneuploidy of chromosome 8 in circulating tumor cells(CTCs)correlated with therapeutic efficacy for advanced gastric cancer(AGC) patients. In this follow-up study performed on the same population of AGC patients, we investigated whether and how aneuploidy of chromosome 8 in CTCs correlates with patients' clinical prognosis.Methods: The prospective study was performed on 31 patients with newly diagnosed AGC. Previously established integrated subtraction enrichment(SE) and immunostaining-fluorescence in situ hybridization(i FISH)platform was applied to identify, enumerate and characterize CTCs. Quantification of CTCs and analysis of their aneuploidy of chromosome 8 were performed on patients before and after therapy.Results: CTCs were measured in 93.5% of AGC patients, and two CTC subtypes with diverse threshold values were identified, multiploid CTCs with the threshold of ≥2 per 7.5 m L and multiploid plus triploid CTCs with the threshold of ≥4, which were found to significantly correlate with poor progression-free survival(PFS) and overall survival(OS). In particular, patients with ≥10% increased multiploid CTCs after an initial 6 weeks of therapy had poor PFS and OS, whereas improved PFS and OS were observed on those who had ≥10% decreased multiploid CTCs. After adjusting for clinically significant factors, ≥10% increased post-therapy multiploid CTCs was the only independent predictor of PFS and OS.Conclusions: Aneuploidy of CTCs correlates with prognosis of AGC patients. Quantitative comparison monitoring multiploid CTCs before and after therapy may help predict improved or inferior prognosis and chemoresistance.Yilin Li Xiaotian Zhang Jifang Gong Qiyue Zhang Jing Gao Yanshuo Cao Daisy Dandan Wang Peter Ping Lin Lin Shen 2016Chinese Journal of Cancer Research2016,28,6:7
3The applications of hypervalent iodine(Ⅲ) reagents in the constructions of heterocyclic compounds through oxidative coupling reactions显示文摘Hypervalent iodine(Ⅲ)reagents have been vastly used in many useful organic transformations.In this review article,we highlight the strategies that used the common hypervalent iodine(Ⅲ)reagents as oxidants to synthesize the heterocyclic compounds,based on the patterns of bond formation during the construction of the heterocyclic backbones.ZHENG ZiSheng ZHANG-NEGRERIE Daisy DU YunFei ZHAO Kang 2014Science China Chemistry2014,57,2:6

7Relationship between head and neck cancer therapy and some genetic endpoints显示文摘Head and neck cancer(HNC) is the sixth most common human malignancy worldwide. The main forms of treat ment for HNC are surgery, radiotherapy(RT) and che motherapy(CT). However, the choice of therapy de pends on the tumor staging and approaches, which are aimed at organ preservation. Because of systemic RT and CT genotoxicity, one of the important side effects is a secondary cancer that can result from the activity of radiation and antineoplastic drugs on healthy cells Ionizing radiation can affect the DNA, causing single and double-strand breaks, DNA-protein crosslinks and oxidative damage. The severity of radiotoxicity can be directly associated with the radiation dosimetry and the dose-volume differences. Regarding CT, cisplatin is stil the standard protocol for the treatment of squamous cell carcinoma, the most common cancer located in theoral cavity. However, simultaneous treatment with cisplatin, bleomycin and 5-fluorouracil or treatment with paclitaxel and cisplatin are also used. These drugs can interact with the DNA, causing DNA crosslinks, double and single-strand breaks and changes in gene expression. Currently, the late effects of therapy have become a recurring problem, mainly due to the increased survival of HNC patients. Herein, we present an update of the systemic activity of RT and CT for HNC, with a focus on their toxicogenetic and toxicogenomic effects.Eliana Maria Minicucci Glenda Nicioli da Silva Daisy Maria Fávero Salvadori 2014World Journal of Clinical Oncology2014,5,2:2
8Investigation of combined Brillouin gain and loss in a birefringent fiber with applications in sensing显示文摘The most general model of elliptical birefringence in an optical fiber is extended to describe a transient Brillouin interaction including both gain and loss. The effects of elliptical birefringence cause a Brillouin spectral shape distortion, which is detrimental for fiber sensing techniques. The model investigates the effects of birefringence and the corresponding evolution of spectral distortion effects along the fiber, and also investigates regimes where this distortion is minimal.Daisy Williams Xiaoyi Bao Liang Chen 2014Chinese Optics Letters2014,12,12:2

10Effects of polarization on stimulated Brillouin scattering in a birefringent optical fiber显示文摘The most general model of elliptical birefringence in an optical fiber has been developed for a steady-state and transient stimulated Brillouin scattering interaction.The impact of the elliptical birefringence is to induce a Brillouin frequency shift and distort the Brillouin spectrum—which varies with different light polarizations and pulsewidths.The model investigates the effects of birefringence and the corresponding evolution of spectral distortion effects along the fiber,providing a valuable prediction tool for distributed sensing applications.Daisy Williams Xiaoyi Bao Liang Chen 2014Photonics Research2014,2,5:2
